Dr. Lonsbary is a cognitive psychologist who is curious about how mood affects memory. She recruited 60 high school students and divided them into three groups. Group A listened to a five-minute piece of music intended to make them feel happy (a song titled "Don't Worry, Be Happy"). Group B listened to a five-minute piece of music intended to make them feel sad (a song titled "Alone Again"). Group C listened to no music and instead was asked to sit quietly for five minutes (thought to make them feel neutral). When a participant would come to her laboratory, Dr. Lonsbary would greet the participant and then ask him or her to draw a card. Participants who drew a 1, 2, or 3 were assigned to Group A. Participants who drew a 4, 5, or 6, were assigned to Group B. Participants who drew a 7, 8, or 9, were assigned to Group C. The participants were then given an unlabeled CD to listen to based on their group assignment. The CD contained either the song selection or five minutes of silence. They were then escorted into a different room, where they were greeted by a research assistant who conducted the experiment. The research assistant sat the participants in front of a computer screen and told them that a list of 25 words would be displayed on the screen. They were instructed to listen to the CD with headphones while trying to memorize the list of words. All participants were given the same list of 25 words to remember. When five minutes had passed, the screen displayed a question asking them whether they felt happy, sad, or neutral. After the participant responded, a new screen was displayed asking them to type in all the words they could remember from the list of 25 words. All participants were given three minutes to type the words they remembered. Afterward, the participant was thanked and dismissed. In response to the mood question, a majority of Group A participants said they were happy, a majority of Group B participants said they were sad, and a majority of Group C participants said they were neutral in their mood. Dr. Lonsbary found the following results in response to the number of words remembered How many conditions/levels of the independent variable were in Dr. Lonsbary's study?

Todd is studying the effect of popularity on academic success for his research methods project. He decides to measure popularity by asking each elementary school student to tell him how many friends he or she has. He assumes that more friends means the student is more popular. Which of the following best describes this variable? A qualitative variable A categorical variable An other-report measure A ratio scale of measurement

A ratio scale of measurement

What is the difference between a ratio scale of measurement and an interval scale of measurement? A ratio scale of measurement has a zero value that actually means "nothing" or "the absence of something," but an interval scale does not. An interval scale of measurement is a type of measurement used for categorical measurements, but a ratio scale is used for quantitative measurements. A ratio scale of measurement cannot be used to compare people's scores, but interval scales can (e.g., Phillip is twice as fast). An interval scale has equal intervals, but a ratio scale does not.

A ratio scale of measurement has a zero value that actually means "nothing" or "the absence of something," but an interval scale does not.

Explain why we do not say that a single study proves a theory or that a single study disproves a theory. Be sure to include the following: weight of the evidence and research as probabilistic

A single study does not prove a theory because although a study today may find support for a theory, a study done tomorrow may not find support for that theory. A single study cannot disprove a theory because the single study may have been poorly conducted. Further, a disconfirming study may mean that the theory may need to be amended or altered, rather than completely dismissed. Rather than rely on just one study, we should look at the weight of the evidence to see what many different studies have found. This also lowers the risk of one study being an outlier (research is probabilistic).

Paul wakes up on Tuesday morning and none of the lights or the appliances in his apartment are working. What theory might explain why this is happening? What could Paul do to test your theory? How is this an example of the theory-data cycle in science

A theory as to why Pauls lights and appliances are not working in his apartment would be the transformer blew and there is a power outage in his entire apartment. To test my theory, Paul could observe other rooms in his building and ask his neighbors if they have power or not. This is an example of the theory-data cycle, because there is a theory that the power is out in Pauls apartment due to a transformer being blown, there are research questions that come from this theory are his neighbors appliances and lights working or not, there is a research design where Paul will ask his neighbors or observe the rooms around him to see if other members of the apartment have electricity or not, this leads to a hypothesis that since Pauls lights and appliances do not work, his neighbors appliances and lights must not work which leads to the data. If the data he collects does not support his theory that a transformer blew, he should redesign his study to have better research questions such as "did I pay my power bill" or revise his research design. If his theory is supported by the data, then he will be able to find a way to fix his power and understand why his appliances and lights do not work.

Although not all psychology majors become producers of research, they can still benefit from learning about how research is conducted. Name two benefits of learning how to become a producer of research.

By becoming a producer of research, you can share your findings with the rest of the world that can be beneficial for curing illnesses, increasing a person's happiness, and many other factors. Another reason why becoming a producer of research can be beneficial is while you may not be able to trust other people who produce research, you can trust yourself and will know the limitations and workings of your own study.

Dr. Sheffield is a clinical psychologist who specializes in treating pathological gambling. Pathological gambling is defined as being unable to resist impulses to gamble. Bothered by not having a good measure that he can give to clients to determine whether they are suffering from this condition, he creates a new measure of pathological gambling. The measure has 15 questions, and it takes 20 minutes to complete. Dr. Sheffield gives his measure to his supervisor (also an expert in pathological gambling), who says that his measure appears to test all the components of pathological gambling, including feeling restless when attempting to stop gambling, jeopardizing jobs to keep gambling, and using gambling to escape from problems. This provides evidence that Dr. Sheffield's measure has which of the following? Criterion validity Content validity Predictive validity Discriminant validity

Question 1 reads, "I tend not to think about other people as much as I think about myself." Question 2 reads, "I do not have a high opinion of myself." Question 3 reads, "I think other people think I am really special." Dr. Valencia is concerned about the validity of the measure of narcissism recommended by her colleague. She sends a copy of the measure to her coauthors to look at and they all tell her it looks like it will measure narcissism. She now has evidence of which of the following? Content validity Face validity Discriminant validity Concurrent validity

Dr. Sheffield is a clinical psychologist who specializes in treating pathological gambling. Pathological gambling is defined as being unable to resist impulses to gamble. Bothered by not having a good measure that he can give to clients to determine whether they are suffering from this condition, he creates a new measure of pathological gambling. The measure has 15 questions, and it takes 20 minutes to complete. Dr. Sheffield has now decided that he wants to test his measure on some university students (who some estimates say have a 6% prevalence rate of compulsive gambling). He has a group of 100 university students complete his measure. He also has them complete two other measures (one that measures addictive behavior in general and one that measures general attitudes toward gambling). He finds that his new measure is positively associated with each of these other measures. This procedure has provided evidence for the ________ of Dr. Sheffield's measure. Discriminant validity Predictive validity Convergent validity Content validity

Dr. Katz is interested in studying self-esteem. He is especially curious as to whether people who have higher self-esteem say the words I and me more often than do those who have low self-esteem. He has decided to poll people and ask them how often they say these words during the day. Explain why you would advise him not to use this method and explain what alternative you would propose.

I would not advise Dr. Katz to use this method, because it would be very difficult, if not close to impossible that a person would be able to recall every single time a person used I and me. I and me could also be used without being related to self-esteem. For example, if I say I would like a sandwich, this does not relate to whether I have high or low self-esteem, It just means I am hungry. An alternative I would propose would be to create a survey with questions that are more detailed while regarding self-esteem and ask questions such as: I like my ideas better than the ideas of people around me- completely agree, somewhat agree, somewhat disagree, completely disagree. this is for self-esteem, how to measure other variable.

What does it mean that "reliability is necessary but not sufficient for validity"? Reliability and validity are the same concept. If a measure is reliable, it is also valid. Reliability and validity are unrelated concepts. If a measure is valid, it is also reliable.

If a measure is valid, it is also reliable.

Dr. Lonsbary is a cognitive psychologist who is curious about how mood affects memory. She recruited 60 high school students and divided them into three groups. Group A listened to a five-minute piece of music intended to make them feel happy (a song titled "Don't Worry, Be Happy"). Group B listened to a five-minute piece of music intended to make them feel sad (a song titled "Alone Again"). Group C listened to no music and instead was asked to sit quietly for five minutes (thought to make them feel neutral). When a participant would come to her laboratory, Dr. Lonsbary would greet the participant and then ask him or her to draw a card. Participants who drew a 1, 2, or 3 were assigned to Group A. Participants who drew a 4, 5, or 6, were assigned to Group B. Participants who drew a 7, 8, or 9, were assigned to Group C. The participants were then given an unlabeled CD to listen to based on their group assignment. The CD contained either the song selection or five minutes of silence. They were then escorted into a different room, where they were greeted by a research assistant who conducted the experiment. The research assistant sat the participants in front of a computer screen and told them that a list of 25 words would be displayed on the screen. They were instructed to listen to the CD with headphones while trying to memorize the list of words. All participants were given the same list of 25 words to remember. When five minutes had passed, the screen displayed a question asking them whether they felt happy, sad, or neutral. After the participant responded, a new screen was displayed asking them to type in all the words they could remember from the list of 25 words. All participants were given three minutes to type the words they remembered. Afterward, the participant was thanked and dismissed. In response to the mood question, a majority of Group A participants said they were happy, a majority of Group B participants said they were sad, and a majority of Group C participants said they were neutral in their mood. Dr. Lonsbary found the following results in response to the number of words remembered. What type of design did Dr. Lonsbary use in her study?

Independent-groups design

Dr. Sheffield is a clinical psychologist who specializes in treating pathological gambling. Pathological gambling is defined as being unable to resist impulses to gamble. Bothered by not having a good measure that he can give to clients to determine whether they are suffering from this condition, he creates a new measure of pathological gambling. The measure has 15 questions, and it takes 20 minutes to complete. To test his measure, Dr. Sheffield gives his measure to a group of people in Gamblers Anonymous (GA) and another group of people in Alcoholics Anonymous (AA). He finds that people in the GA group have higher scores on his measure than people in the AA group. This procedure is known as a: Test-retest paradigm Known-groups paradigm Prediction paradigm Group evaluation paradigm

Dr. Uchida is a clinical psychologist who is curious about how people deal with natural disasters (e.g., hurricanes, tornados, earthquakes). His previous research suggests that there is a relationship between how much people feel their emotional well-being was affected by the natural disaster and their likelihood of developing posttraumatic stress disorder (PTSD) symptoms. However, he is curious as to whether the effect of emotional well-being goes through another variable, that of social support. He conducts a study in which he asks 174 men and women affected by the 2011 tsunami in Japan to report on how their well-being was affected by the tsunami, the social support felt after the storm, and the number of PTSD symptoms. Dr. Uchida finds support for his proposed relationship. However, in examining his data more closely, he finds that the relationship between emotional well-being and PTSD symptoms is stronger for men than for women. Dr. Uchida's finding that the relationship between emotional well-being and PTSD symptoms is stronger for men than for women suggests which of the following? Emotional well-being is a mediating variable. Dr. Uchida's study was conducted unethically. Dr. Uchida's study was conducted incorrectly. Participant sex is a moderating variable.

Imagine that you are trying to measure people's stress. Provide an example of measuring stress using a self-report measure, a physiological measure, and a behavioral measure.

Self-report- on a scale from 1-10, how stressed would you rate yourself? You ask the question and they tell you. Physiological measure- hook the person up to a machine that measures their heart-rate. put them in certain situations and watch their level of heart rate lower or rise. Look at biological factors Behavioral measure- observe the person and see if they look to be experiencing stress. For example, you could watch someone during a test. If they have calm posture and look to be content, you can assume they are not stressed. If they look frantic, are shaking, or showing other signs of stress, they are most likely stressed.

A sample is always ________ a population. Smaller than More interesting than More scientific than More expensive to measure than

Faking good is also known as: Acquiescence Fence sitting Socially desirable responding A response set

Socially desirable responding

Explain why socially desirable responding happens. Name one way to decrease the likelihood of its occurrence.

Socially desirable responding happens when people do not want to go against the "right" idea of something. They do not want their opinion to contradict what other people may think and someone may chose a socially desirable response to seem more politically correct or to refrain from judgement. One way to decrease the likelihood of this occurrence would be to inform participants at least once that there is no right or wrong answer to a question and that they will not be judged.

Stout, Dasgupta, and colleagues wanted to find out why women's outstanding performance on science and math tests in high school and college correlates so weakly with their eventual interest in pursuing careers in those fields. In high school and college, girls increasingly earn math and science grades equal to or better than the grades of their male peers. But when it comes to choosing a career, more men than women decide to pursue math or science careers. The psychologists asked female students studying biology, chemistry, and engineering to take a very tough math test. All the students were greeted by a senior math major who wore a T-shirt displaying Einstein's E = mc2 equation. For some volunteers, the math major was male. For others, the math major was female. This tiny tweak made a difference: Women attempted more questions on the tough math test (comprising 10 questions) when they were greeted by a female math major rather than a male math major. In the study described above, consider the measured variable. Provide both a conceptual definition and an operational definition for it

The conceptual definition is math effort, attraction to math, or math attempt. (Generally, the study was attempting to look at how female students approach math.) The operational definition is the number of math problems the students attempted to solve.

Which of the following is true? People are very good judges of the reasons for their behavior People are better able to remember vivid memories.

Anton and his friends are discussing a study he read about in his developmental psychology class. In the study, the researcher made the claim that a majority of middle school students who are bullied have low self-esteem. Clarissa questions the study, saying, "I am not sure that I am convinced—I am not sure you can really measure being bullied." Quinn also questions the study, saying, "Which middle school students did they study? I am curious if they included both private and public school students."

Deci and Ryan (1985, 2001) have proposed that there are three fundamental needs that are required for human growth and fulfillment: relatedness, autonomy, and competence. Susan predicts that students who have these needs met in their psychology class feel happier and more satisfied with the class. She collects data and finds that students who feel more related and competent do feel happier but that feeling more autonomous does not seem to matter. Susan thinks that maybe autonomy is only necessary when people are in situations in which they are not being evaluated. Susan's hypothesis was not completely supported by her data. What does this mean? The theory may need to be amended. The theory is completely wrong. Susan must have analyzed the data incorrectly. Susan must have collected the data incorrectly.

The theory may need to be amended.

Dr. Oswald conducts a study examining the relationship between the number of friends one has and the experience of daily stress and life satisfaction. She randomly samples 1,500 elderly men and women in the Memphis, Tennessee, area in the southern United States. Below are her findings. < Life satisfaction and experience of daily stress: r = -.57 ( p = .01) < Number of friends one has and experience of daily stress: r = .09, not sig. < Number of friends one has and life satisfaction: r = .36 ( p = .04) Dr. Oswald creates a scatterplot of the relationship between the experience of daily stress and life satisfaction. In doing so, she realizes there are three scores that seem to be very extreme and are nowhere near the other points on the scatterplot. Specifically, it appears that three people report very high levels of daily stress and very low levels of life satisfaction. Which of the following statements is NOT true? A. These scores may have strengthened the correlation between these two variables. B. These scores are more likely to have an effect because of the large sample size. C. These scores may be considered outliers. D. These scores are more likely to have an effect because they are extreme on both variables

These scores are more likely to have an effect because of the large sample size.

Why are techniques like cluster and multistage sampling just as externally valid as simple random sampling? They all measure every member of the population of interest. They all rely on large samples. They all use lists of all population members They all contain elements of random selection.

Professor Kramer has decided to measure how happy his students are with his teaching this semester. He is teaching two classes this semester—Psychology and Law and Introduction to Neuroscience. Dr. Kramer plans to give his survey only to his Psychology and Law students because he sees them on Mondays, Wednesdays, and Fridays and he can spare the class time (unlike in his Introduction to Neuroscience class, which only meets on Tuesdays and Thursdays). Which of the following is true? This will lead to a biased sample because the Psychology and Law students have a lot of time to complete the survey. This will lead to a biased sample because the type of students who take Psychology and Law may be different from the type of students who take Introduction to Neuroscience. This will lead to a biased sample because of self-selection. The will lead to a sample that is representative of both of his classes.

This will lead to a biased sample because the type of students who take Psychology and Law may be different from the type of students who take Introduction to Neuroscience.

Dr. Li is interested in creating a measurement of religiosity. According to the dictionary, religiosity is "the quality of being religious; piety; devoutness." He creates a measure comprising 10 statements. People respond to each statement using the following scale (1 = strongly disagree, 3 = neither agree nor disagree, 5 = strongly agree). Some of the statements are below. Statement 1: "I believe in a religion." Statement 2: "Part of who I am stems from my religious beliefs." Statement 3: "I believe that religion is unnecessary." Name two types of reliability that apply to Dr. Li's measure and how each one could be established, given the above scenario.

Two types of reliability that apply to Dr. Li's measure are internal reliability and test-retest. We would test internal reliability (but score #3 as reverse) because participants should be answering in the same way. The participants should answer about the same no matter how the question is phrased. Test-retest reliability should be used to make sure answers are consistent.

Dr. Valencia is considering conducting a study examining whether narcissistic people have poorer social interactions than those who are not narcissistic. One of her first tasks is to determine which of her participants are narcissistic and which are not. She decides to use the scale created by a colleague, the Mayo scale. Question 1 reads, "I tend not to think about other people as much as I think about myself." Question 2 reads, "I do not have a high opinion of myself." Question 3 reads, "I think other people think I am really special." Dr. Valencia is concerned whether her measure will really measure narcissism or if it will measure some other related concept. She is concerned about the scale's ________. Operational definition Validity Reliability Convenience

Consider two variables: income and relationship satisfaction. Name and describe the three types of associations using these two variables

income and relationship satisfaction. People who make more money are less satisfied with their relationships since they are working more and spend less time with their partner. this is a negative association since income is up and satisfaction with their relationship is going down. the variables are moving away from each other people who make more money have more satisfication in their relationships since they are less worried =. positive association since both variables are going up. variables are helping each other. peoples income is not related to their satisfaction in their relationships- zero association since they are not related

Name and describe the three types of claims, including how someone can distinguish between them.

the three types of claims are frequency claims, causal claims, and association claims. Frequency claims only have one measured variable and an example of this would be 1/34 high school students commit suicide (not an actual statistic). association claims are when there are at least two measured variables in a study, and this needs a greater since of external validity, or can be generalized. causal claims have one measured variable and one manipulated variable. These are not as common as other claims and focus more on the internal validity of the study, or if there are confounds/alternative explanations. The language for these claims usually imply causation more than other types of claims.
