Introduction to Psychology, James W. Kalat, Combination of Chapter 2, 3, 6, 9, 11

ego depletion

a study by Roy Baumeister, a state, produced by acts of self-control, in which people lack the energy or resources to engage in further acts of self-control

Interpreter

gazzaniga (2000) infers that the left hemisphere has a function that he calls the interpreter.

standardization

the process of evaluating the questions, establishing rules for administering a test, and interpreting the scores. to determine the meaning of a test's scores, the authors of a test determine the mean and the distribution of scores for a random or representative sample of the population. IQ tests are revised periodically.

Motivation

the process that determines the reinforcement value of an outcome

Acquisition 取得

the process that establishes or strengthens a conditioned response

binding problem 拘束力のある問題

the question of how separate brain areas combine forces to produce a unified perception of a single object

adaptive testing

the range of items used is adapted to the performance of the individual.

Mental Processes (the mind) and brain activity are?

the same

Cognitive Psychology

the scientific study of all the mental activities associated with thinking, knowing, remembering, and communicating

Psychology

the scientific study of behavior and mental processes,

social psychology

the scientific study of how we think about, influence, and relate to one another

synapse シナプス

the specialized junction between one neuron and another, a neuron releases a chemical that either excites or inhibits the next neuron

Job design

The scientific-management approach emphasizes efforts to find the best, most efficient, safest way to do a job. according to the human-management approach, jobs should be made interesting enough to give workers a sense of achievement.

20. Suppose a father is red-green deficient and a mother has two genes for normal color vision. What sort of color vision will their children have?

The sons receive a gene for normal color vision from the mother, and a Y chromosome (irrelevant to color vision) from the father. They will have normal color vision. The daughters receive a gene for normal color vision from the mother and a gene for red-green color deficiency from the father. They will also have normal color vision, but they will be carriers who can pass the red-green deficiency gene to some of their children

14. How does stereotype threat affect the validity of a test?

14. because stereotype threat leads some people to per- form at a lower level than they would otherwise, it decreases the validity of the test.

15. What is an advantage of fMRI in comparison to PET scans?

15. An fMRI scan does not expose the body to radiation

15. Suppose that you score 80 on your first psychology test. The mean for the class is 70, and the standard deviation is 5. On the second test, you receive a score of 90. This time the mean for the class is also 70, but the standard deviation is 20. Compared to the other students in your class, did your performance improve, deteriorate, or stay the same?

15. Even though your score rose from 80 on the first test to 90 on the second, your performance actually deteriorated in comparison to other students' scores. A score of 80 on the first test was 2 standard deviations above the mean, better than 98 percent of all other students. A 90 on the second test was only 1 standard deviation above the mean, a score that beats only 84 percent of the other students.

15. Should we be more impressed with results when the 95 percent confidence intervals are large or small? Should we be more impressed if the p value is large or small?

15. In both cases, smaller. A small 95 percent confidence interval indicates high confidence in the results. A small p value indicates a low probability of getting such a large difference merely by chance.

15. Why did Kinsey's results differ from those of later surveys?

15. Kinsey interviewed a nonrandom, nonrepresentative sample of people.

15. What aspects of birdsong learning set it apart from classical and operant conditioning?

15. The most distinctive feature is that birdsong learning occurs when the learner makes no apparent response and receives no apparent reinforcement

What depletes our self control resources?

Decisions Resisting Temptation Paying Attention Comprehension Use of Self- Control

Monozygotic

Generally identical Twins

Origins of sexual orientation

Genetic influences and prenatal environment affect sexual orientation. on the average, heterosexual and homosexual men differ in the size of a structure in the hypothalamus that contributes to certain aspects of sexual behavior. less is known about the role of experience in the development of sexual orientation.

Intrinsic motivation

based on the pleasure that the act itself provides

prosocial behavior

behavior intended to benefit other people

Ineffectiveness of mental explanations

behaviorists prefer to describe what the individuals do instead of inferring what they are trying to do or what they are feeling while they do it

Self efficacy 自己効果

belief of being able to perform the task successfully Whether we imitate a behavior depends on whether we believe we are capable of duplicating it. 自分が行動することで結果が起きるという「結果予測」と、それがうまくできるかどうかという「効力予期（＝自己効力）」との兼ね合いから、「自分にもできる」とどれだけ思ってるかってこと。その自己効力感に関係する要因

Sterotype

belief that members of a group are distinguished by some set of shared characteristics, doesn't necessarily math reality.

Unconditioned reflexes (automatic connections)

between stimulus such as food and a response such as secreting digestive juices

Trust vs. Mistrust; Erikson's Stages of Socioemotional Development (socioemotional child development)

birth to 18 months; helpless baby's basic needs are met by responsible caregiver, fostering trust & establishing that world is a safe place to be independent agents

Endorphins エンドルフィン

blind to the opiate receptors

Reinforcement 強化

process of increasing the future probability of the most recent response Edward Thorndike defined reinforcement as the process of increasing the future probability of the preceding response. ひとたび条件付が成立した後で、無条件刺激と条件刺激を再び条件付すると、反射がより強くなることです。いわば、条件付の上乗せができる法則です。この法則は、スポーツやアートの達人が、素晴らしい反応を見せることをよく説明

Continuous reinforcement 固定強化

provide reinforcement for every correct response 行動をするたびに、必ず何かの行動を強化するものが与えられる お金を入れたら、自分の欲しいものが手に入るわけです。 その欲しいものを手に入れるための行動が、強化されること

Fixed ratio 固定比率

provides reinforcement only after a certain (fixed) number of correct responses

General Research Principles

psychological researchers use scientific methods, but they face problems (1) sampling: people might be unusual in some way (2) people who know they are in a research study often behave differently just because they know someone is watching

Applied behavior analysis (behavior modification) 応用行動分析

psychologist tries to remove the reinforcers for unwanted behaviors and provides reinforcers for more acceptable behaviors

clinical psychologist

psychologist who treats people serious psychological problems or conducts research into the causes of behavior

Skepticism about extrasensory perception.

psychologists care- fully scrutinize claims of extrasensory perception because the evidence reported so far has been unreplicable and because the scientific approach includes a search for parsimonious explanations.

Fluid and crystallized intelligence

psychologists distinguish between fluid intelligence (reasoning ability) and crystallized intelligence (acquired and practiced skills).

Charles Spearman

psychometric approach to intelligence, based on the measurement of individual differences in performance. 1904

Negative punishment

punishment by avoiding something good

scientific-management approach

you should experiment to find the best way to do the job, select appropriate workers, and train them well t do it the right way

Two key points

you use all of your brain, not some percentage of it. although most people take for granted that their mind is separate from the brain, the evidence points to the contrary: mind activity and brain activity are the same thing. to lose part of one is to lose part of the other.

Neurons

your brain consists of an enormous number of separate cells

physical changes in early adulthood (physical adult development)

- early adulthood characterized by ~30 years old - decline in strength/speed - decline in perceptual abilities like hearing and sight

7. The cerebellum is important for behaviors that require which of the following? (a) prolonged exertion (b) accurate timing (c) reflexive action (d) coordinating vision with hearing

7b,

Learning curve 学習曲線

a graph of the changes in behavior that occur over the course of learning

convenience sample,

a group chosen because of its ease of study. 多くの研究者が大学生の研究を使いすぎています。これはいくつかの目的には十分ですが、

set point

a level that the body works to maintain

y-chromosome y染色体

a male has one x-chromosome and one of these chromosomes

The Correlation Coefficient 相関係数

a mathematical estimate of the relationship between two variables. 相関の強さを測定するために、研究者は相関係数、すなわち2つの変数間の関係の数学的推定値を使用します。相関係数が0の場合は、一貫した関係がないことを示します。 11または21の係数は完全な関係を示します。 負の相関は、正の相関と同じくらい便利です。たとえば、ゴルフを練習する頻度が高いほど、ゴルフの得点が低くなるため、ゴルフの練習は得点と負の相関があります。人々がより多くの魚介類を食べる国では、うつ病はあまり一般的ではないので、魚介類の摂取はうつ病と負の相関があります

Standard deviation (SD),

a measurement of the amount of variation among scores in a normal distribution.

Spontaneous recovery 自発的回復

a temporary return of an extinguished response after a delay; requires no additional CS-UCS pairings if the conditioned stimulus is not presented at all for some time after extinction and is then presented again, the conditioned response may return. The return is called spontaneous recovery. 馴化によって一旦起こらなくなった反応は休憩をはさむと復活する

Entity theory

a theory that a person's level of intelligence is fixed and unchangeable

Unconditioned stimulus (UCS) 無条件刺激 学んでいない

an event that automatically elicits an unconditioned response 学ばなくても、特定の反応を引き出す刺激

Reinforcer 強化剤

an event that follows a response and increases the later probability or frequency of that response

Neurotransmitters and behavioral disorders

an excess or deficit of a particular neurotransmitter can lead to abnormal behavior, such as that exhibited by people with parkinson's disease.

Action potential

an excitation that travels along an axon at a constant strength, no matter how far it travels.

self-fulfilling prophecy

an expectation that causes you to act in ways that make that expectation come true. Which causes the other person who your acting onto react based on how you acted.

theory 科学理論

an explanation or model that fits many observations and makes accurate predictions. 複製可能なデータが何らかの仮説を支持するならば、結局研究者は理論を提案する。 科学理論は推測以上のものです。 それは多くの観測に適合し、正確な予測をする説明またはモデルです。

sex-linked genes 性関連遺伝子

genes located on the x or y chromosome

cerebellum 小脳

"little brain", part of the hindbrain, is important for any behavior that requires aim or timing, such as tapping out a rhythm, judging which of two visual stimuli is moving faster and judging whether one musical tempo is faster or slower than another

Parsimony and Degrees of Open-Mindedness

"perpetual motion machine," 「永久運動機械」 特許庁: closed-mind, so disagree to build 物理学者: open-mind, so agree to build it and search どんな仕事でもエネルギーを浪費するかなどが見たい

Different Psychology vs Science

(1) history: 科学はアマチュアの仕事から徐々に始まりました。何世紀にもわたり、医師やその他の職業に就いていた人々は、星や惑星の位置を記録したり、化学物質を混合したり、動物を見たりして結果を観察する. 初期の心理学の教授たちは、様々なことを教えた。 心理学は、自然科学の方法を哲学の問題のいくつかに適用して、新しい科学を始めるという意図的な試みとして始まる。初期の心理学の教授たちは、生物学者がすでに感覚器官について発見したこと以外は、率直に言って教えることはあまりありませんでした。 (2) ethics: 化学者は彼らが建物を爆破しない限り、化学薬品の瓶に彼らが望むほとんど何でもすることができます。人を扱う心理学者には厳しい制限があります

Terminal bouton ターミナルボタン

(presynaptic ending) a typical axon has several branches, each ending with a little bulge called ...

Correlation Coefficient

+1 = Means two values vary in same direction (perfectly) -1 = opposite direction (perfectly) 0 = Nothing vary's together

8. on average, old people who read more books are less likely to develop alzheimer's disease. What conclusion can we draw from this result? (a) reading books tends to prevent alzheimer's disease. (b) people who are already starting to develop alzheimer's disease don't read many books. (c) We can draw neither of these conclusion

, 8c,

Evaluation Erikson's Theory (socioemotional child development)

- Erikson's theory is based primarily on case studies, so some consider it an unfounded theory - idea of capturing each developmental stage in one concept limits other important developmental tasks (there's more than one aspect within each stage of development)

Intuition (5)

- Hunches or guesses like a gut feeling - Sometimes right / Sometimes wrong - Used when we lack knowledge - Substitute a different question, sometimes without realizing it - intuitive answers suffer overconfidence

Common Sense (3)

- Includes Ideas or knowledge we think "any sensible person" would have - Sometimes correct / Sometimes wrong - Can contradict itself

Piaget's Theory of Cognitive Development (cognitive child development)

- Jean Piaget (Swiss, 1896 - 1980) believed children actively construct their cognitive world as they go through a series of stages - basically, children create and use schemas to make sense of their surroundings, and these schemas developed by assimilation and accommodation - *theorized that humans go through four stages in understanding the world, and each stage involves qualitatively different ways of understanding the world*

Vygotsky's Sociocultural Cognitive Theory

- Lev Vygotsky (1962) recognized that cognitive development depends on cultural context - children are "apprentice thinkers" who develop as they interact with more knowledgable adults - these "expert thinkers" spur cognitive development by interacting with a child at a level just above what the child previously mastered; these interactions provide framework for thinking that is always at the level a child can strive to attain - **goal of cognitive development is to learn the skills needed to be competent in their particular culture**

Anecdotes (5)

- The story of a particular event - Can be heard / read / personal experience - Usually involves informal observations rather than careful systematic measurements - Sometimes very true / Sometimes very wrong - More persuasive than it should be

aging & the brain (physical adult development)

- adults can grow new brain cells - possible to slow effects of aging by exercising brain - brain has remarkable repair capabilities - lateralization means using both hemispheres to maintain mental abilities

Newborn/infant brain development (physical child development)

- at birth and early infancy, the brain's 100 billion neurons have minimal connections - during the first two years of life, dendrites branch out and neurons interconnect - synaptic connections increase dramatically during childhood - brain continually reorganizes and alters tissue organization; 3-6 years = rapid growth in frontal lobe; these brain changes are a result of both nature and nurture

parent & peer influences (socioemotional adolescent development)

- best parenting style is authoritative; parents must act as managers & effectively monitor - peer relationships teach adolescents how to have intimate relationships

Formal Operational Stage; Piaget's Stages of Cognitive Development (cognitive child development)

- develops at ~11 to ~15 years of age, continues through adulthood - characterized by more abstract and logical thinking than concrete operational stage's thinking i.e. more hypothetical thinking processes like making predictions and using logic to come up with hypotheses - idealistic thinking => comparing how things are to how they could be - hypothetical deductive reasoning => identification of the best path of reasoning rather than solving problems through trial and error

Sensorimotor Stage; Piaget's Stages of Cognitive Development (cognitive child development)

- lasts from birth to ~2 years - infants construct understanding of the world by coordination sensory experiences with motor actions in a trial and error system; transition from reflexive patterns to complex sensorimotor patterns; beginning of the use of symbols/patterns in thinking - object permanence develops, meaning infants develop the understanding that objects and events continue to exist even when they cannot directly be seen, heard, or touched

Preoperational Stage; Piaget's Stages of Cognitive Development (cognitive child development)

- lasts from ~2 to ~7 years - thought is characterized by *egocentrism* - decisions are *intuitive* rather than logical - characterized by *centration*, the tendency to focus on only one aspect of a situation at a time - children begin to represent their world SYMBOLICALLY using words/language, images, drawings, etc. - children cannot yet think about/perform operations i.e. they cannot comprehend that actions can be reversible and restored to original state

Concrete Operational Stage; Piaget's Stages of Cognitive Development (cognitive child development)

- lasts from ~7 to ~11 years - involves process of using operations to replace intuitive reasoning with logical reasoning *in concrete situations* - operations tend to be related to properties of certain objects i.e. understanding that actions can be reversible, understanding that even though play-doh changes its shape, it is still play-doh - characterized by classifying things into different sets/subsets and considering interrelations - **logical reasoning in ACTUAL scenarios, not hypothetical ones**

Research on Adult Socioemotional Development

- meaning comes not just from past but present as well socioemotional selective theory: narrowing of social contacts & increase in positive emotion; active satisfaction from present moment, not future

physical changes in middle/late adulthood (physical adult development)

- middle/late adulthood characterized by ~40-50 years old - wrinkles, age spots, hair thinning/graying, height loss, weight gain - women experience menopause - selective optimization with compensation (older adults match their goals with their current abilities and compensate for decline)

Newborn/infant motor & perceptual skills (physical child development)

- motor and perceptual skills develop together and mutually promote each other - experience influences the speed of motor development

research on moral development

- supportive parenting yields increased helping/comforting of others - children show a conscience at ~3 years old

Good Measurements tools need?

-Reliability -Validity Repeatable vs predictable

decision fatigue

a state of depleted willpower caused by making decisions, which can affect subsequent decisions by causing people to fail to think and choose carefully

Drive

a state of unrest or irritation that energizes on behavior after another until one of them removes the irritation.

Industry vs. Inferiority; Erikson's Stages of Socioemotional Development (socioemotional child development)

6 years to puberty; achieving industry means mastering knowledge and intellectual skills, and failure to master leads to feelings of inferiority

6. "I want my employees to enjoy their work and to feel pride in their achievements." Does that statement reflect a belief in the human-relations approach or the scientific-management approach?

6. It reflects the human-relations approach

1. The introduction to this chapter described people who stood in line to visit a foul-smelling flower. Would that action make sense in terms of drive-reduction, incentive, or homeostasis views of motivation?

1. The action is a response to an incentive, the opportunity for an unusual experience. It would be harder to explain in terms of drive-reduction or homeostasis.

11. After damage to the ventromedial hypothalamus, an animal's weight eventually reaches a higher than usual level and then fluctuates around that amount. What has happened to the set point?

1. The set point increased.

11. Identify each of the following examples using the terms in Table 6.1: (a). Your employer gives you bonus pay for working overtime. (b). You learn to stop drinking caffeinated beverages at night because they keep you awake. (c). You put on sunscreen to decrease the risk of skin cancer. (d). If you get a speeding ticket, you will temporarily lose the privilege of driving the family car.

11. a. positive reinforcement; b. punishment; c. avoidance learning or negative reinforcement; d. punishment

11. Under what condition does a person with full vision experience temporary motion blindness?

11. During and slightly before a voluntary eye movement

Five Benefits of Planning

1) Avoiding rather than resisting temptation 2) Using the power of pre-commitment 3) Preventing decision fatigue 4) Don't waste resources by holding that to do list in memory 5) Train your automaticity to be helpful

1. Which part of a neuron receives input from other neurons (ordinarily)? Which part sends messages to other neurons?

1. Dendrites receive input from other neurons. Axons send mess

1. You read about two explanations for g. What would each of them predict about whether something could impair intelligence in one way and spare it in another

1. If all intelligent abilities depend on a single underlying factor, then anything that impaired that factor (some type of brain damage, for example) would impair all the intelligent abilities. For analogy, an injury that impairs running would also impair jumping. However, if intelligent abilities correlate because they usually grow together, we can imagine something that impairs one ability much more than others—as in the case of Williams syndrome (discussed in Chapter 8). For analogy, amputating a finger does not harm the legs.

1. How does a meta-analysis relate to replicability?

1. If some studies replicate an effect and others do not, a researcher may conduct a meta-analysis that combines all studies as if they were one large study.

1. Why do behaviorists reject explanations in terms of thoughts?

1. Previous events and current stimuli are responsible for thoughts, and therefore the events and stimuli are the real causes of behavior.

10. Suppose you want to reinforce a child for doing chores around the house, and you don't know what would be a good reinforcer. According to the disequilibrium principle, how should you proceed?

10. Begin by determining how the child ordinarily spends his or her time when given unlimited opportunities. Then find which of these activities the child has been deprived of recently. The opportunity to do one of those activities should be reinforcing.

10. Most students find that their scores on any standardized test increase the second time they take it. Does the improvement indicate that the test is unreliable?

10. Not necessarily. If most people's scores improve by about the same amount, then those who had the highest scores the first time still have the highest scores the second time.

10. Over the past few decades, the average age of starting puberty has become younger. What is one explanation, based on this chapter?

10. People have been gaining weight and therefore producing more leptin. Leptin facilitates the onset of pubertly

10. On average, the more medicines people take, the more likely they are to die young. Propose alternative explanations for this correlation.

10. Perhaps people get sick from complications caused by taking too many pills. Or maybe the people who take many medicines are those who already had serious illnesses.

10. How does cortical blindness differ from blindness caused by eye damage?

10. Someone with cortical blindness loses visual imagery, even in dreams. However, sun- light continues to regulate the person's wake-sleep cycle. Also, some people with cortical blindness have blindsight, in which they can indicate the location of a stimulus or other properties of the stimulus without conscious perception of it. Someone with total eye damage can continue to have visual imagery, but light does not drive the wake-sleep cycle, and blindsight cannot occur.

Mean IQ score

100, has changed throughout history but tests have been revised to make sure it stays at 100

10. an elementary school tests whether physical exercise influences children's performance. Children in each class are randomly assigned to physical exercise or movie watching for 30 minutes each afternoon. All children take the same tests, and the instructors compare their performances. The indepen- dent variable is _____, and the dependent variable is _____. (a) exercise versus movie watching . . . scores on tests (b) scores on tests . . . the number of students in each class (c) the number of students in each class . . . Exercise versus movie watching (d) scores on tests . . . exercise versus movie-watching

10a,

10. Which of the following defines the binding problem? (a) The question of how the brain creates a unified experience from sensations analyzed by separate brain areas (b) The question of how a person converts sensory information into motor output (c) The question of how the brain compares information in the left hemisphere to information in the right hemisphere (d) The question of how people coordinate movement of the left hand with movement of the right hand

10a.

11. On average, drug addicts who regularly attend counseling sessions are more likely to stay drug-free than those who drop out. Propose alternative expla- nations for this correlation.

11. Perhaps the counseling sessions are helpful to people who want to quit drugs. Or perhaps the people with the most serious addictions are the ones who quit.

11. Can a test have high reliability and low validity? Can a test have low reliability and high validity?

11. Yes, a test can have high reliability and low validity. A measure of intelligence determined by dividing head length by head width has high reliability (repeatability) but presumably no validity. A test with low reliability cannot have high validity, however. Low reliability means that the scores fluctuate randomly. If the test scores cannot even predict a later score on the same test, then they can hardly predict anything else.

11. a double-blind study helps alleviate the problems caused by which of the following? (a) falsifiability (b) independent variables (c) failure to replicate a study (d) demand characteristics

11d,

12. Parietal lobe damage interferes with which aspect of vision?

12. It interferes with identifying the object's locatio

12. What evidence indicates important nongenetic influences on eating and weight gain?

12. People eat more when in social groups than when eating alone. People's expectations about foods, based on such things as the name of the food, influence intake. People eat more when portion sizes are larger.

12. An instructor wants to find out whether the frequency of testing in an introductory psychology class influences students' final exam performance. The instructor gives weekly tests in one class, just three tests in a second class, and only a single midterm exam in the third class. All three classes take the same final exam, and the instructor then compares their performances. Identify the independent variable and the dependent variable in this experiment.

12. The independent variable is the frequency of tests during the semester. The dependent variable is the students' performance on the final exam

12. If physics graduate departments tried admitting some students with low quantitative scores on the GRE and English departments tried admit- ting some students with low verbal scores, what would happen to the predictive validity of the tests?

12. The predictive validity of the tests would increase. The predictive validity is low when most students have nearly the same score. It is higher when students' scores are highly variable.

12. Identify which schedule of reinforcement applies to each of the following examples: (a) You attend every new movie that appears at your local theater, although you enjoy about a quarter of them. (b) You are told that a company will soon announce a job opportunity, and you want to be one of the first to apply. You don't know when they will post the announcement, so you keep checking every hour or two. (c) You tune your television set to an all-news cable channel, and you look up from your studies to check the sports scores every 30 minutes.

12. a. variable ratio. (You will be reinforced for about a quarter of your entries to the theater but on an irregular basis.) b. variable interval. (Checking will be effective after some interval of time, but the length of that time is unpredictable.) c. fixed interval.

12. consider the following distribution of scores: 6, 4, 17, 1, 10, 4, 14, 4, 12. The mean is ____, the median is ____, and the mode is ____. (a) 8...6.. . 4 (b) 8 . . . 10 . . .4 (c) 6...8.. . 4 (d) 4...6..

12a,

13. A company hiring salespeople proposes to test applicants on their ability to speak Spanish. Is this policy biased against people who don't speak Spanish?

13. It depends. A test is biased if it underpredicts or over- predicts performance for a group of people. If the sales- people will be working in a neighborhood with many Spanish-speaking customers, this test will accurately predict success on the job, and it would therefore be unbiased. However, if the sales staff works in a neighborhood with no need to use Spanish, the test is biased.

13. What evidence suggests that imitation produces mirror neurons as opposed to the idea that mirror neurons produce imitation?

13. It is possible to train neurons to respond to one kind of movement the person produces and a different movement the person watches. If people can learn to develop these "anti-mirror" neurons, then presumably, they could also learn to develop mirror neurons

13. What are the arguments against regarding anorexia as a result of emotional problems?

13. Most people with anorexia had no psychiatric problems before developing anorexia. Standard forms of psycho- therapy and drug therapies are not very effective with an- orexia. Also, a treatment based on increasing body warmth and avoiding excessive exercise has been reported to be highly effective.

13. Which of the following would an experimenter try to minimize or avoid? Falsifiability, independent variables, dependent variables, blind observers, or demand characteristics.

13. Of these, only demand characteristics are to be avoided. If you did not remember that falsifiability is a good feature of a theory, check page 29. Every experiment must have at least one independent variable (what the experimenter controls) and at least one dependent variable (what the experimenter measures). Blind observers provide an advantage.

13. Of the procedures characterized in Table 6.1, which one applies to supporting attempts at increased mobility? Which one applies to decreasing attention to inappropriate complaints?

13. Support for increased mobility is positive reinforcement. Decreasing attention for inappropriate complaints is punishment. Reinforcement increases a behavior and punishment decreases it

13. We should be more impressed with a result if the 95 percent confidence intervals are _____. We should be more im- pressed with a result if the p value is _____. (a) large . . . large (b) large . . . small (c) small . . . large (d) small . . . small

13d.

2. A lower level of need does not always take priority over one at a higher level. Maslow's hierarchy ignores parent- ing and overemphasizes self-actualization. Also, goals vary among cultures.

2. How did Loeb explain why certain animals turn toward the light?

2. According to Loeb, light from the side caused greater muscle tension on one side of the body. Therefore, muscles on one side or the other moved more vigorously than those on the other side. This imbalance of movement continued until the light stimulation on both sides was equal.

2. Suppose a new performer demonstrates what appears to be an amazing ability to read people's minds or predict the fu- ture. Before anyone investigates, why do scientists assume it is more likely to be a trick than a supernatural power?

2. Scientists prefer the more parsimonious explanation. They resist an extraordinary conclusion if they can find a simpler one.

2. If a mouse and a giraffe both get pinched on the toes at the same time, which will respond faster? Why?

2. The mouse will react faster because the action potentials have a shorter distance to travel in the mouse's nervous system than in the giraffe's

20. Most studies find that gay men have approximately the same levels of testosterone in their blood as heterosexual men of the same age. Do such results conflict with the suggestion that prenatal hormonal conditions can predispose certain men to homosexuality?

20. Not necessarily. The suggestion is that prenatal hormones can alter early brain development. In adulthood, hormone levels are normal, but certain aspects of brain development have already been determind

21. Why is it misleading to talk about "the gene" for some behavior or ability?

21. Almost every aspect of behavior depends on the combined influence of many genes and environmental influences. Also, any gene affects more than one outcome

22. What are the effects of acetyl and methyl groups on a gene?

22. Acetyl groups loosen a ball of DNA and expose the genes within it to greater expression. Methyl groups attach to a gene and inactivate it

24. Suppose someone studies adopted children who developed severe depression and finds that many of their biological parents had depression, whereas few of their adopting parents did.

6a.

6. Suppose some researcher reports a low correlation between stress and depression. One possible explanation is that stress had little to do with depression in that researcher's sample of the population. What is another possible explanation for these results? (a) The people varied widely in their level of stress. (b) The researcher made inaccurate measurements of either stress or depression. (c) people with great stress are likely to become depressed.

(b) Be confident of your ability to resist the temptation. (c) Watch what happens to other people who yield to temptation. (d) remind yourself of ethical norms.

6d,

6. suppose on some new IQ test tall people generally get higher scores than short people. Which of the following would be the strongest evidence that the test is biased against short people? (a) The fact that short people get lower scores is in itself strong evidence that the test is biased. (b) It would be strong evidence if short people believed the questions were unfair to them. (c) It would be strong evidence if it were revealed that most of the test's authors were tall. (d) It would be strong evidence if someone demonstrated that short people get better grades in school than the test scores predict.

6d,

7. What is meant by a "standardized" test?

7. A standardized test has clear rules for administering the test, and previous studies have established the norms to which a new score can be compared. In most cases, the authors of the test have taken care to remove or revise any unclear, poorly worded items.

7. What are some factors that con- tribute to high job satisfaction

7. Factors associated with high job satisfaction include high ability to perform the job, a happy personality, a perception that the pay scale is fair, and old age.

7. If classical conditioning depend- ed entirely on presenting the CS and UCS at nearly the same time, what result should the experimenters have obtained in Rescorla's experiment?

7. If classical conditioning depended entirely on presenting the CS and UCS at nearly the same time, the rats in both groups would have responded equally to the conditioned stimulus, regardless of how often they received the unconditioned stimulus at other times.

7. Some people with attention deficit disorder report that they experience benefits for the first few hours after taking methylphenidate pills but begin to deteriorate in the late afternoon and evening. Why?

7. Remember what happens after taking cocaine: Neurons release dopamine and other transmitters faster than they resynthesize them. Because cocaine blocks reuptake, the supply of transmitters dwindles, and the result is lethargy and mild depression. The same process occurs with methylphenidate but more slowly and to a smaller degree.

7. Which of the following is an example of a variable-ratio schedule? (a) stargazing in hopes of finding a comet (b) opening oysters in hopes of finding a pearl (c) Buying ice cream cones at a place that offers a free one after every 10 purchases (d) taking a test that is given in class once a week

(b) If you expect to do poorly on a test, you probably will. (c) on average, test scores are higher for some groups than for others. (d) people tend to stay away from others whom they consider dangerous.

7b.

7. research on rats suggests that bulimia nervosa resembles what other condition? (a) sleep apnea (b) drug addiction (c) Bipolar disorder (d) Phobia

7b.

7. Which of the following is evidence against pavlov's explanation for classical conditioning? (a) conditioning always occurs if a cs repeatedly precedes the ucs. (b) other things being equal, longer cs-ucs delays lead to weaker evidence of conditioning. (c) in some cases the cr is different from the ucr.

7c,

(b) intrinsic motivation increases both quality and quantity of performance. (c) extrinsic motivation mainly increases quantity, and intrinsic motivation mainly increases quality. (d) extrinsic motivation mainly increases quality, and intrinsic motivation mainly increases quantity.

7c,

7. Suppose researchers find a 10.4 correlation between the number of vitamin pills people take and their mental health. Which conclusion, if any, can we draw from this result? (a) taking vitamin pills improves mental health. (b) Strong mental health improves people's probability of taking action to maintain health. (c) Wealthier people are more likely than average to take vitamin pills, and also to be mentally healthy. (d) We can draw none of these conclusions.

7d

8. What is the behavioral effect of anxiolytic drugs?

8. Anxiolytic drugs reduce anxiety and help people relax

8. What jobs are especially vulnerable to job burnout?

8. Job burnout is especially common in the helping professions, such as nursing or therapy.

8. The correlation between students' grades and their scores on a self-esteem questionnaire is very low, not much above 0. Why might that be?

8. One possibility is that grades are unrelated to self- esteem. Another possibility is that we used an inaccurate measurement of either self-esteem or grades or both. If anything is measured poorly, it cannot correlate strongly with anything els

8. Why is it unlikely that improved education accounts for much of the Flynn effect?

8. Why is it unlikely that improved education accounts for much of the Flynn effect?

8. Suppose you have already learned to flinch when you hear the sound of a dentist's drill. Now your dentist turns on some soothing back- ground music during the drilling. The back- ground music is paired with the pain just as much as the drill sound is. Will you learn to flinch at the sound of that background music?

8. You will not learn to flinch at the sound of the back- ground music. Because the drill sound already predicted the pain, the new stimulus is uninformative and will not be strongly associated with the pain.

8. What is a transformational leader? (a) someone who is seen as visionary and stimulating (b) someone who makes an organization more efficient by proper rewards (c) someone who is still learning how to be a leader (d) someone who has recently changed his or her style of leadership

8a.

8. Why do many cold remedies interfere with sleep? (a) They decrease sympathetic nervous system activity and increase parasympathetic activity. (b) They decrease parasympathetic nervous system activity and increase sympathetic activity. (c) They increase production of hormones, especially the sex hormones. (d) They decrease production of hormones, especially the sex hormones.

8b,

8. rats repeatedly received one stimulus followed by a ucs. Then they repeatedly received that stimulus and a second stimulus, followed by the same ucs. What happened, and what is this phenomenon called? (a) rats stopped responding to either of the two stimuli. This is the spontaneous recovery effect. (b) rats learned to respond equally to the first and second stimuli. This is the stimulus generalization effect. (c) rats started responding to the second stimulus instead of the first stimulus. This is the blocking effect. (d) rats showed little response to the second stimulus. This is the blocking effect.

8d.

9. Insulin levels fluctuate over the course of a day. Would they be higher in the middle of the day, when people tend to be hungry, or late at night, when most are less hungry

9. Insulin levels are higher in the middle of the day (LeMagnen, 1981). As a result, much of your meal is stored, and you become hungry again. At night, when insulin levels are lower, you draw from your supplies to make more glucose.

9. An overdose of opiates produces a life-threatening decrease in breathing and heart rate. Large doses of marijuana do not produce those effects. Why not?

9. Opiate receptors are abundant in the medulla, which controls heart rate and breathing. The medulla has few receptors sensitive to marijuana.

9. Suppose we find a 0.8 correlation between students' report- ed interest in psychology and their grades on a psychology test. What conclusion can we draw?

9. We can conclude only that if we know either someone's interest level or test score, we can predict the other with reasonably high accuracy. We cannot conclude that an interest in psychology will help someone learn the material or that doing well on psychology tests increases someone's interest in the material. Either conclusion might be true, of course, but neither conclusion follows from these results. A correlational study cannot demonstrate a cause-and-effect relationship.

9. Someone has just devised a new "intelligence test." It measures your intelligence by dividing the length of your head by its width and then multiplying by 100. Will the scores on this test be reliable?

9. Yes! To say that a test is "reliable" is simply to say that its scores are repeatable. This test will give useless scores, but they will be highly reliable (repeatable).

9. When a bell rings, an animal sits up on its hind legs and drools; then it receives food. Is the animal's behavior an example of classical conditioning or operant conditioning? So far, you do not have enough information to answer the question. What else do you need to know before you can answer

9. You need to know whether the bell always predicts food (classical conditioning) or whether the animal receives food only when it sits up (operant conditioning).

9. in what parts of the adult human brain, if any, can new neurons form? (a) in all parts of the brain (b) only in the cerebral cortex (c) only in the hippocampus and basal ganglia (d) in none of the brain

9c,

9. on average, students who attend class every day get better grades than those who frequently miss. Which conclusion, if any, can we draw from this result? (a) attending class helps people improve their grades. (b) Brighter students, who are likely to get good grades, are more likely than average to attend class conscientiously. (c) We can draw neither of these conclusions.

Case histories.

A case history is a detailed research study of a single individual, generally someone with unusual characteristics. 大きな制限がある

Inferring causation. 推論 因果関係

A correlational study cannot uncover cause-and-effect relationships, but an experiment can. Inferring causation. correlational≠causation 第一に、相関関係は私たちが予測をするのを助けます。第二に、相関研究は後の実験への道を開き、それが結論につながるかもしれません。たとえば、両親の半数にスパンキングをやめさせるように説得することができれば、子供の行動が改善するかどうかがわかります。

Correlations. 相関研究

A correlational study examines the relationship between variables that are outside the investigator's control. The strength of this relationship is measured by a correlation coefficient that ranges from 0 (no relationship) to plus or minus 1 (a perfect relationship). 相関研究では、研究者はどちらも制御せずに2つの変数間の関係を測定します。たとえば、人の身長と体重の間の相関関係、または外向性質問票の得点と誰かの友達の数の間の相関関係を測定する

mind-body problem

A fundamental psychological issue: Are mind and body separate and distinct, or is the mind simply the physical brain's subjective experience?

Steps in a scientific study.

A scientific study goes through the following sequence of steps: hypothesis, method, results, and interpretation. Because almost any study is subject to more than one possible interpretation, we base our conclusions on a pattern of results from many studies.

Surveys.

A survey is a report of people's answers on a questionnaire. It is easy to conduct a survey and, unfortunately, easy to get misleading results. A study of the prevalence of certain beliefs, attitudes, or behaviors based on people's responses to questions. 調査結果が有用または誤解を招く可能性がある方法もある 時折うそをつきます 質問がどのように表現されたか、またどのような選択肢が提供されたかを尋ねます。わずかに異なる表現でも、異なるパーセンテージを生み出す可能性 an organization words the questions of a survey to encourage the answers they hope to receive.

standardized test

A test with uniform procedures for administration and scoring. Many standardized tests allow a person's performance to be compared with the performance of other individuals.

Depressants うつ病

Alcohol, Benzodiazepines

Variability in Human Sexual Behavior

Alfred Kinsey, who conducted the first extensive survey of human sexual behavior, found that sexual activity varies more widely than most people realize.

Random assignment

An experimenter randomly assigns individuals to the experimental and control groups. All participants should have an equal probability of being chosen for the experimental group. The experimenter uses a chance procedure, such as drawing names out of a hat, to make sure that all participants have the same probability of being assigned to a given group.

Overcoming experimenter bias.

An experimenter's expectations influence the interpretations of behavior and the recording of data. To ensure objectivity, investigators use blind observers who do not know what results are expected. In a double-blind study, neither the observer nor the participants know the researcher's predictions. the tendency of an observer (unintentionally, as a rule) to misperceive the results. 実験者の偏見は、観察者が（意図せずに、一般に）結果を誤解する傾向

False Knowledge

Anecdotes, common sense, intuition, illusory correlations, confirmation bias, and good intentions are all inadequate as guides to fully and accurately understand ourselves and others, sometimes we see patterns that aren't there

Why does the desire to prove the stereotype wrong backfire?

Anxiety and Distraction have been shown to be among the causes -it requires a belief that others have lower expectations

Median

Arranging the results from small to big and finding the middle one arrange the scores in order from the high- est to the lowest. 2,5,10 then median is 5

conditioned taste aversion 味覚嫌悪

Associating a food with illness First documented by John Garcia and his colleagues (garcia, ervin, & Koelling, 1966). animals, including people, learn to avoid foods, especially unfamiliar ones, if they become ill afterward. This type of learning occurs reliably after a single pairing, even with a long delay between the food and the illness. illness is associated much more strongly with foods than with other stimuli.

Adding together changes of speed and direction elicited by various stimuli result in

Complex behavior

Acetylcholine アセチルコリン

increases brain arousal

Sampling.

Because psychologists hope to draw conclusions that apply to a large population, they try to select a sample that resembles the total population—either a representative sample or a random sample. To apply the results to people worldwide, they need a cross-cultural sample. getting a random or representative sample is important in any research, but especially with surveys. 2つの集団を比較するとき、研究者はそれらの集団の同様のサンプルを必要とします

Replicability.

Because researchers generally publish only the results that look impressive, an unknown number of the reported results may have arisen by accident. Psychologists are becoming more interested in trying to the replicate results.

Behaviorists' interest in learning.

Behaviorists' goal is to explain behavior without relying on terms such as idea or understanding. much of invertebrate behavior can be described in simple terms, but the greater challenge was to explain learning.

Anxiolytics

Benzodiazepines, widely used to relieve anxiety, can also relax muscles and promote sleep. anxiolytics and alcohol act by facilitating inhibitory synapses.

Illusory correlations. 錯覚的な相関関係

Beware of illusory correlations— relationships that people think they observe between variables after casual observation. 実際には存在しない相関関係があると思うことがあります。例えば、多くの人々は、砂糖を摂取すると子供たちが活動亢進すると信じています。しかしながら、広範な研究は活性レベルに対する糖の影響をほとんど見いださず、そしていくつかの研究は糖が挙動を落ち着かせることを見出した。。つまり、人々は自分たちが期待するものを見ているのです。 人々が2つの出来事（例えば、砂糖と活動レベル）の間の関係を見ることを期待するとき、彼らは関係を支持し例外を無視する事件を覚えています。 満月は人間の行動に影響を与えるという一般的な考えを考えます。しかし、データを注意深く見直しても、月の満ち欠けと犯罪または精神病との間に関係は見られない

Test bias

Bias means inaccuracy of measurement. psychologists try to remove from a test any item that tends to be easy for one group of people to answer but difficult for another group. They also try to evaluate whether the test as a whole makes equally accurate predictions for all groups

What influences Intelligence

IQ score Genes Environment

Distribution of IQ scores

IQ tests have a mean of 100 and a standard deviation of about 15 or 16, depending on the test. however, the mode (most frequent score) is higher than 100, and a bulge of lower scores exists.

Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) Wechsler Intelligence Scale for Children-Fifth Edition (WISC-V),

IQ tests originally devised by David Wechsler, and later modified by others,

23. If our society changed so that it provided an equally good environment for all children, would the heritability of behaviors increase or decrease

If all children had equally supportive environments, the total amount of variation in behavior would decrease, but whatever variation remained would have to depend largely on heredity (because differences in the environment have been minimized). Therefore heritability would increase.

nature of reinforcement

If someone has been deprived of the opportunity to engage in a behavior, then the opportunity to return to that behavior is reinforcing.

Entity theory in teachers

Defining intelligence

Intelligence is difficult to define. psychological researchers try to measure it, hoping to learn something from the measurements.

Elements to Student Success

Intelligence, Self-regulation, and Cognitive Strategies

Overcoming temptations

It is better to avoid tempting situations than to try to combat temptation. resisting a temptation helps people to later resist the same type of temptation, but it often weakens their ability to resist other types. seeing another person yield to temptation increases the risk of also yielding, unless one sees the other person as an outsider, different from oneself. a reminder about ethical norms decreases cheating in some situations

How does IQ measure Intelligence?

It is controversial but not well -the definition of intelligence is disputed over -IQ scores have been misused in many ways

Hallucinogens 幻覚薬

LSD, MDMA("ecstasy"), Rohypnol and GHB, Phencyclidine(PCP or "angel dust") hallucinogens induce sensory distortions. lsd acts at one type of serotonin synapse. mdma produces stimulant effects at low doses and hallucinogenic effects at higher doses.

Characteristics of motivated behaviors

Motivated behaviors vary from time to time, from situation to situation, and from person to person. They persist until the individual reaches the goal.

Motivation as Incentive

Motivations are partly under the control of incentives—external stimuli that pull us toward certain actions. Both drives and incentives control most motivated behaviors.

Extrinsic and intrinsic motivations

Motivations include the possible rewards and the joy of the task itself.

Mean, median, and mode.

One way of presenting the central score of a distribution is via the mean, determined by adding all the scores and dividing by the number of individuals. Another way is the median, which is the middle score after all the scores have been arranged from highest to lowest. The mode is the score that occurs most frequently.

Basis for classical conditioning

Pavlov believed that conditioning occurred because presenting two stimuli close to each other in time developed a connection between their brain representations. Later research showed that animals do not treat the conditioned stimulus as if it were the unconditioned stimulus. also, being close in time is not enough. Learning occurs if the first stimulus predicts the second stimulus. csとucsの間の遅延が長ければ長いほど、コンディショニングは弱くなりますが、他のことは同じです。ただし、csとucsを時間内に近付けるだけでは不十分です。それらが離れて発生するよりも一緒に発生することが不可欠

Cognitive and social influences on eating

People eat more in groups than when eating alone. They eat more, drink more, and enjoy their meal more when they have high expectations for the meal, based on such things as the name of the food or the supposed location of the winery. They eat more when they are offered larger portions.

Motivation Conflict

People seldom do anything for just one reason. in general, biological needs take priority over other motivations, but not always.

Central and peripheral nervous systems

The central nervous system consists of the brain and the spinal cord. The peripheral nervous system consists of nerves that communicate between the central nervous system and the rest of the body.

The cerebral cortex

The cerebral cortex has four lobes: occipital lobe (vision), temporal lobe (hearing and some aspects of vision), parietal lobe (body sensations), and the frontal lobe (preparation for movement). damage in the cerebral cortex produces specialized behavioral deficits.

Leadership

The demands of leadership depend on the situation. organizations generally work best if many people can take a leadership role, depending on the situation. When an organization thrives, its leader is perceived as visionary. leaders perceived as using rewards to get employees to do their work efficiently are effective in situations when the business is stable.

the binding problem

Theoretically, it is problematic to understand how one brain area responsible for vision, another area responsible for hearing, and another area responsible for touch combine forces to yield a unified perception of an object. Binding different senses into one experience requires perceiving the various aspects as occurring in the same place at the same time.

Probability of chance results.

Traditionally, psychologists have used inferential statistics to calculate the probability that a given research result could have arisen by chance. That probability is low if the difference between the two groups is large, if the variability within each group is small, and if the number of individuals in each group is large. Currently, the trend is to present the means and 95 percent confidence intervals for each group and let readers see the size of the effect.

Extinction 絶滅

occurs if responses stop producing reinforcements to extinguish a classically conditioned response, repeatedly present the conditioned stimulus (CS) without the unconditioned stimulus (UCS). That is, the acquisition of a response occurs when the CS predicts the UCS; extinction occurs when the CS no longer predicts the UCS A conditioned response can be extinguished by repeatedly presenting the conditioned stimulus by itself in operant conditioning, a response is extinguished if it is no longer followed by reinforcement. 反応が強化を生み出さなくなると絶滅が起こる ＝＞以前は特定のビデオゲームを楽しんでいましたが、最後の数回は退屈に思えたので、ゲームをやめます。 古典的な条件では、絶滅は消滅を意味しません。絶滅は反応を抑制します 滅は忘れることと同じではありません。どちらも学習した反応を弱めるが、それらは異なる方法で発生する。あなたは、思い出させたり練習したりせずに長期間忘れます。絶滅は、無条件刺激なしで条件刺激を知覚するという特定の経験のために起こります。獲得が応答をすることを学んでいるならば、絶滅はそれを抑制

accommodation; Piaget's Theory of Cognitive Development (cognitive child development)

occurs when individuals adjust their schemas to new information i.e. *new experience promotes a new way of doing/understanding something*

Law of effect

of several responses made to the same situation, those which are accompanied or closely followed by satisfaction to the animal will, other things being equal, be more firmly connected with the situation, so that when it recurs, they will be more likely to recur. Hence, the animal becomes more likely to repeat the responses that led to favorable consequences even if it doesn't know why

Self reinforcement and self punishment

once people have decided to try to imitate a certain behavior, they set goals for themselves and may even provide their own reinforcement

Categories of reinforcement

positive, negative, punishment, and extinction. Positive Reinforcement. The examples above describe what is referred to as positive reinforcement. Think of it as adding something in order to increase a response. For example, adding a treat will increase the response of sitting; adding praise will increase the chances of your child cleaning his or her room. The most common types of positive reinforcement or praise and rewards, and most of us have experienced this as both the giver and receiver. Negative Reinforcement. Think of negative reinforcement as taking something negative away in order to increase a response. Imagine a teenager who is nagged by his mother to take out the garbage week after week. After complaining to his friends about the nagging, he finally one day performs the task and to his amazement, the nagging stops. The elimination of this negative stimulus is reinforcing and will likely increase the chances that he will take out the garbage next week. Punishment. Punishment refers to adding something aversive in order to decrease a behavior. The most common example of this is disciplining (e.g. spanking) a child for misbehaving. The reason we do this is because the child begins to associate being punished with the negative behavior. The punishment is not liked and therefore to avoid it, he or she will stop behaving in that manner. Extinction. When you remove something in order to decrease a behavior, this is called extinction. You are taking something away so that a response is decreased.
