Personality disorder: OCD
foot in the door
Persuasive technique involving making a small request before making a bigger one
mind control
Process by which freedom of choose and action, either as an individual or a group, is compromised to distort perception, motivation, cognition, and behavior. Ex. Jonestown, Milgram and Zimbardo.
naturalistic intelligence
The ability to work with biology and work with and around natural settings. Students have the ability to observe nature and see patterns
Triarchic Theory of Intelligence
View of intelligence; proponents argue that that intelligent behavior arises from a balance between analytical, creative, and practical abilities. Experiential intelligence- Componential intelligence- Contextual intelligence-
correlation coefficient

neurons that connect afferent and efferent neurons
Exchange-rational
refers to the theory that we are rational actors, who perform a cost-benefit analysis of our decisions
disorganized schizophrenia
type of schizophrenia characterized by severely disturbed thought processes, frequent incoherence, disorganized behavior, and inappropriate affect.
Componential intelligence
(also known as analytical intelligence) the traditional idea of intelligence. Includes ability to logically reason and think abstractly. Also includes the ability to communicate and think mathematically. This type of intelligence can be evaluated by standard tests of intelligence (e.g. IQ tests)
Experiential intelligence
(also known as creative intelligence) the ability to familiarize oneself with new circumstances and form new concepts. For example: If you move to a foreign country and you are able to learn the new language, you are exhibiting experiential intelligence.
Semantic networks
(also known as frame networks) are neural networks that signify lingual or logical relationships between ideas.
Contextual intelligence-
(also known as practical intelligence, or "street smarts") this is the ability to apply one's knowledge base to the world around them. Example: You have learned that UV rays from the sun can give you skin cancer, so when the sunlight becomes intense, you move to sit in the shade
Wernicke's aphasia
-parietal lobe damage part of the temporal lobe involved in understanding language, problems comprehending speech, expressing meaning
reduce cognitive dissonance
1) Modify our cognition: I don't smoke that much 2)Trivialize : make less important...oh its not that big of a deal 3)Add: adding more cognitions...if i exercise more smoking won't be that bad 4) Deny: Smoking and cancer are unrelated
convergence
A binocular cue for perceiving depth; the extent to which the eyes converge inward when looking at an object. The greater the inward strain, the closer the object.
undifferentiated schizophrenia
A catchall term used when schizophrenic symptoms either do not conform to the criteria of any one type of schizophrenia or conform to more than one type.
groupthink
A situation in which group members seek unanimous agreement despite their individual doubts
in group
A social group toward which a member feels respect and loyalty (shared interest and identity)
James-Lange
A theory of emotion that states that a stimulus results in physiological arousal, which then leads to a secondary response in which emotion is consciously experienced.
identity moratorium
An adolescent's choice of a socially acceptable way to postpone making identity-achievement decisions. Going to college is a common example.
rational choice
An approach that assumes people act rationally in their self-interest, seeking to maximize value.

counter attitudinal
Inconsistent attitude related to cognitive dissonance and talks about binge drinking on 21st birthday (the person binge drinking isn't someone who usually drinks) participants do boring task and tell a white lie about how enjoyable it was. Some were paid $1, others paid $20. Later, asked openly how much they had enjoyed the task. Those who were paid $20 said it was boring. Those who had been paid $1 rated the task as significantly more enjoyable.

Internal consistency
The extent to which all the items on an instrument are measuring the same attribut
Internal validity
The extent to which an experiment shows convincingly that chagnges in behavior are a functon of the independent variable and not a result of uncontrolled or unknown variables.
Attributional bias
The tendency to attribute one's own negative behavior to external causes and one's positive actions to internal states
fundamental attribution error
The tendency to attribute other people's behavior to dispositional (internal) causes rather than situational (external) causes. A good example would be if someone tripped you and you assumed that they had done it on purpose when in fact they happened to have put their leg out to stretch or lean back. Another example is if someone kicked a cat, and you assumed it was because they hated your cat when in fact it was because the cat was not visible to them. (Say it stepped in front of them suddenly.)
Status quo bias
The tendency to favor the "here and now" and to reject potential change.... many people eat the same thing for breakfast day after day, for example, or walk to work in exactly the same pattern, without variation, refusing to try new food while visiting a country
Framing bias
The two scenarios above are identical, but statistically people will make different decisions based upon how the information is portrayed. We generally respond better to positively portrayed information (98% survival) than to negatively portrayed information (2% mortality). An information-processing bias in which a person answers a question differently based on the way in which it is asked (framed).
Expectation bias
When we see what we want to see; we seek out confirming information and ignore disconfirming information confirmation bias ex. supporters of Bush and Kerry during the 2004 election were able to ignore contradictory statements made by their preferred candidate. Without any effort on their parts, their brains stepped in to protect their current beliefs.
differential association theoretical perspective
a theory that explains deviance as a learned behavior determined by the extent of a person's association with individuals who engage in such behavior
catatonic schizophrenia
a type of schizophrenia marked by striking motor disturbances, ranging from muscular rigidity to random motor activity
implicit attitudes
attitudes that influence a person's feelings and behavior at an unconscious level
explicit attitudes
attitudes that we consciously endorse and can easily report
Dementia
chronic disorder of mental processes, particularly the ability to recall. It can be caused by an injury or disease of the brain; it is not contagious. In addition to memory loss, other symptoms of dementia include changes in personality and cognitive abilities (e.g. reasoning).
Weber Fechner law
dI/ I= K
A scientist investigating the Weber-Fechner law detects a just-noticeable difference for a subject when shifting from a 5 kg to an 8 kg mass. When repeating the trial, how many kilograms must be added to a 15 kg mass to replicate the effect?
dI/I=K (8-5)/5 =x/15 15 X 3= 45 5x= 45 x=9 kg
referent power
derived from one's personal attraction
attitude polarization
describes changes in attitudes among people in groups - tendency to go to the extreme.
projective personality assessment
diagnostic personality test using unstructured stimuli to evoke responses that reflect aspects of an individual's personality. Two prominent examples of projective tests are the Rorschach Inkblot Test (Rorschach, 1921) and the Thematic Apperception Test (TAT) (Morgan & Murray, 1935). The former asks respondents to interpret symmetrical blots of ink, whereas the latter asks them to generate stories about a series of pictures.
Induce compliance
door in the face A smaller request after a bigger request does improve compliance.
informal social control
exercised by a society without stating any rules or laws. It is expressed through norms and customs. Social control is performed by informal agents on their own in an unofficial capacity. Traditional societies mostly embed informal social control culture to establish social order.
Huntington's disease
fatal genetic condition with no cure. Its symptoms include memory loss and dementia, as well as involuntary movements of the limbs. The disease is caused by neurons that are genetically programmed to degenerate over time. neuroleptics and benzodiazepines
Automation bias
favor suggestions from automated decision making systems and to ignore contradictory information made without automation, even if it is correct. This bias takes the form of errors of exclusion and inclusion: an automation bias of exclusion takes place when humans rely on an automated system that does not inform them of a problem error of inclusion arises when humans make choices based on incorrect suggestions relayed by automated systems.[2] Automation bias has been examined across many research fields.[1] Some factors leading to an over-reliance on automation include inexperience in a task lack of confidence in one's own abilities a reflexive trust of the automated system a lack of readily available alternative information, as a way of saving time and effort on complex
Decay Theory
if long-term memories are not recalled often, it will become harder and harder (if not impossible) to remember them. It is also theorized that our inability to remember certain pieces of information may be due to the natural physiological death of neurons, especially as we age.
conditioned stimulus
in classical conditioning, an originally irrelevant stimulus that, after association with an unconditioned stimulus, comes to trigger a conditioned response
Conditioned response
in classical conditioning, the learned response to a previously neutral stimulus
unconditioned response
in classical conditioning, the unlearned, naturally occurring response to the unconditioned stimulus, such as salivation when food is in the mouth
Egocentric bias
individuals recall the past in a self-enhancing manner; e.g. fishermen "remembering" catching bigger and bigger fish.
normative social influence
influence resulting from a person's desire to gain approval or avoid disapproval ex. standing up for a standing ovation even if you didn't think the performance was great...because it would be awk if you didn't
informative social influence
influence resulting from one's willingness to accept others' opinions about reality. conformity that occurs because of the desire to be correct. In Asch's experiment, some of the participants stated that they believed they must be wrong since no one else agreed with them. They changed their answer so that they would be 'right.'
proactive interference
interference where older information learned interferes with the recall of the more recent information
linguistic intelligence
language skills
8 types of intelligence
linguistic, logical-mathematical, spatial, musical, bodily-kinesthetic, interpersonal, intrapersonal, and naturalistic
objective personality assessment
measures specific personality characteristics based on a set of discrete options, such as in the Meyers-Briggs personality assessment. Objective tests involve administering a standard set of items, each of which is answered using a limited set of response options (e.g., true or false; strongly disagree, slightly disagree, slightly agree, strongly agree). Responses to these items then are scored in a standardized, predetermined way. For example, self-ratings on items assessing talkativeness, assertiveness, sociability, adventurousness, and energy can be summed up to create an overall score on the personality trait of extraversion.
efferent neurons
neurons that take information from the brain to the rest of the body
afferent neurons
neurons that take information from the senses to the brain
Imagination inflation
occurs when certain memories are either constructed or exaggerated by the person's imagination. This is one way false memories can be created.
Retroactive interference
occurs when the learning of new information prevents someone from remembering information that was learned previously.
characteristics of creativity
openness to experience, new ideas, an internal locus of evaluation, an ability to toy with elements and concepts, perceiving freshly, concern with outside and inside worlds, ability to defer closure and judgment, and skilled performance of the traditional arts, among others.
schema
overall framework of how we remember something (structure and components of the situation, details, etc.). Schemas can skew information. An example of a schema skewing information: being asked to recall the doctor's examining room that you saw as a child. You may remember certain things that were there, but due to your idea of what a doctor's examining room should look like, you may remember things such as tongue depressors, cotton balls, alcohol, etc., regardless of whether or not they were actually there.
Effort justification
people's tendency to reduce dissonance by justifying the time, effort, or money they have devoted to something that has turned out to be unpleasant or disappointing

The Dissociation Theory
states that the hypnosis patient is experiencing a divided state of consciousness. It is thought that if the patient alters their focus and tunes-out their everyday state of consciousness, they will be able to focus on another more specific and directed state of consciousness.
subjective personality assessment
testers respond freely and give their own interpretations of stimuli Rorschach Inkblot Test, Thematic Apperception Test (TAT),The House-Tree-Person Test,
Post decisional conflict
the dissonance associated with behaving in a counter-attitudinal way. dissonance can be reduced by bringing the attitude into line with the behaviour
Fixation
the failure to see an issue from a new perspective. Sometimes fixation occurs because of a mental set.
Ecological validity
the idea that cognition should be measured in settings and conditions that are as realistic as possible and that the abilities measured should be those needed in real life
primary deviance
the initial act of rule breaking deviance involving occasional breaking of norms that is not a part of a person's lifestyle or self-concept
Regression to the mean
the mean is the phenomenon that if a variable is extreme on its first measurement, it will tend to be closer to the average on its second measurement—and if it is extreme on its second measurement, it will tend to have been closer to the average on its first. significant consideration in the design of experiments
Free choice paradigm
the more "free" choice one has in the decision making process, the more dissonance they will suffer
secondary deviance
the process that occurs when a person who has been labeled a deviant accepts that new identity and continues the deviant behavior
Cannon-Bard
the theory that an emotion-arousing stimulus simultaneously triggers physiological responses and the subjective experience of emotion I see a snake --> I am afraid, and I begin to tremble.
confabulation
the unintended false recollection of episodic memories ex. confusion of an event that happened to someone else with one that happened to you, or a belief that you remember something when it never actually happened
Strain theory
theory that deviance is more likely to occur when a gap exists between cultural goals and the ability to achieve these goals by legitimate means
