Phsych/Soc Review Flashcards
GABA
CNS inhibitory neurotransmitter. When agonized, would act as CNS depressant. Seizures and insomnia.
Acetylcholine
Primary neurotransmitter at neuromuscular junction
Dopamine
neurotransmitter associated with motivation and motor function, cocaine and amphetamine stimulate this
Glutamate
Primary excitatory neurotransmitter of CNS. Stimulant. Can be cause of increased anxiety and stress
Hippocampus
Regulates stress and anxiety.
Medulla
Basic biological functions like respiration and heart rate.
Pons
connects brain stem to cerebrum, may play part in sleep processes
Self selection bias
is related to the reality that certain groups of people may be more willing than others to participate in a study, and therefore the sample may not be an accurate reflection of the population
Stereotype threat
the self-confirming belief that one’s performance will support a negative stereotype about one’s own gender, race or other designation.
Histrionic personality disorder
usually attention seekers, are prone to dramatic displays, and actually want their antics to be witnessed by others.
intersectionality
various forms of oppression or discrimination, such as racism, sexism, or ageism, interact with one another to create a new, heightened form of oppression or discrimination that cannot be fully understood on the basis of its component parts.
Hypothalamus
interface between the nervous and endocrine systems.
cerebellum
involved in balance, coordinated movement, and the storage of non-declarative memory
Explicit memory
Requires conscious, intentional recall
Implicit memory
Automatic, UNCONSCIOUS recall, usually of skills, procedures, or conditioned responses.
Habituation
A decreased response to a stimulus after the stimulus has been presented multiple times, due to a shift of attention away from the stimulus.
Dishabituation
An increased response to a stimulus after habituation has already occurred. The old stimulus is suddenly reacted to as if it were new.
Sensitization
An increased response to a stimulus after the stimulus has been presented multiple times. Sensitization (NOT dishabituation) is the conceptual opposite of habituation.
hippocampus
The hippocampus is then responsible for analyzing these inputs and ultimately deciding if they will be committed to long-term memory. It acts as a kind of sorting centre where the new sensations are compared and associated with previously recorded ones.
Working memory
Working memory describes the form of memory we use to hold onto information temporarily. Working memory is used, for example, to keep track of where we are in the course of a complicated math problem, and what the relevant outcomes of prior steps in that problem are.
Retrospective memory
Retrospective memory is where the content to be remembered (people, words, events, etc) is in the past, i.e. the recollection of past episodes. It includes semantic, episodic and autobiographical memory, and declarative memory in general, although it can be either explicit or implicit.
Prospective memory
Prospective memory is where the content is to be remembered in the future, and may be defined as “remembering to remember” or remembering to perform an intended action. It may be either event-based or time-based, often triggered by a cue, such as going to the doctor (action) at 4pm (cue), or remembering to post a letter (action) after seeing a mailbox (cue)
Classical conditioning
involuntary response to a neutral stimuli
Operant conditioning
a consequence to a voluntary behavior
conditioned stimulus/conditioned response
can result from unconditioned and neutral stimuli to become conditioned, or “accustomed to” . Also known as when the association between the neutral stimuli and conditioned stimulus become acquired.
extinguish
Once an association has been acquired, it can be
extinguished by repeatedly presenting the conditioned stimulus without the unconditioned stimulus. Over time, the animal will stop exhibiting the conditioned response to the conditioned stimulus, and we say that extinction has occurred.
Spontaneous recovery
the animal is not simply forgetting the original association between the conditioned and unconditioned stimuli and will occasionally show a conditioned response to the conditioned stimulus even though the conditioned stimulus has been extinguished
shaping
describes the reinforcement of successive approximations for some target behavior
punishments
Punishments weaken the behavioral response, decrease its frequency, or stop it altogether
reinforcements
Reinforcement strengthen the behavioral response, or increase its frequency.
Escape learning (in response to negative reinforcement)
Subject adopts a behavior to reduce or end an unpleasant stimulus.
Avoidance learning
Subject adopts a behavior to avoid an unpleasant stimulus in the future.
Cones
Less sensitive than rods. Perceive color, used during day, located in fovea only, 20x less than rods
Rods

Feature detection
form, color, motion: Parvo-still Mavro-moving
Rod/cone process
Rod/cone-> bipolar cell-> retinal ganglion cell-> Optic nerve -> brain
Lateral Geniculate Nucleus (LGN)
= Part of the thalamus; think of it as a relay center between the optic nerve and the visual cortex of the occipital lobe.
Visual cortex
Part of the occipital lobe responsible for processing visual stimuli.
processing (parallel)
The visual system processes different aspects of the visual world in separate streams of
information. This is referred to as parallel processing. For instance, motion and color are
processed in different areas. Feature detection is distinguishing between these characteristics.

2) Vestibulocochlear nerve
3) Brain stem
4) Medial Geniculate Nucleus (MGN): Part of the thalamus

Somatosensation
Colloquially called “touch” = Includes touch, texture, pain, pressure, stretching, temperature, and vibration.
10 MOST-FREQUENTLY-CITED GPS: (Gestalt principles)
1) Closure-“When seeing a complex arrangement of elements, we tend to look for a single, recognizable pattern.”
2) Continuation-“Elements arranged on a line or curve are perceived as more related than elements not on the line or curve.”
3) Common Fate-“Elements that move in the same direction are perceived as more related than elements that are stationary or that move in different directions.”
4) Proximity-“Objects that are closer together are perceived as more related than objects that are further apart.”
5) Similarity-“Elements that share similar characteristics are perceived as more related than elements that don’t share those characteristics.”
7) Good Gestalt
8) Symmetry-“People tend to perceive objects as symmetrical shapes that form around their center.”
9) Past Experience-“Elements tend to be perceived according to an observer’s past experience.”
10) Convexity-Convex rather than concave patterns tend to be perceived as figures.

visuospatial sketchpad.
Things to know about neurons:
Remember that neurons:
1) Are frozen in G0 phase (unable to divide)
2) Depend entirely on glucose for energy
3) Don’t require insulin for glucose uptake
4) Have very low glycogen & oxygen storage capability and thus require high perfusion (blood flow)
Self serving bias:
when a person attributes personal successes to internal factors and personal failures to external factors.
Berkson’s fallacy:
the sampling bias that results from selecting both the observed and control population from a hospital setting.
Specific real area bias:
occurs when the sampling for a study occurs at one location, which results in the omission of other populations.

Social inequality:
the social structural condition wherein some people have significantly more resources (money, education, health, and power) than others in the same society.
Meritocracy:
social stratification based on personal merit (not social structural conditions such as social status or health).
Intra generational social mobility:

Dispositional attribution:
generally involve making assumptions about an individual’s personality or character as a way of explaining or accounting for their behavior.
Situational attribution:
involves explaining someone else’s behavior based on influences or circumstances in their environment or culture.
Structural functional theory:
sees social stratification as functionally necessary for society and its members by rewarding those who work the hardest or contribute the most to society.
Symbolic interaction theory:
sees stratification as one factor (out of many) that guides and shapes our interaction with others. It is a micro-level theory that doesn’t successfully explain macro-level phenomena such as social stratification
Social loafing:
exerting lower levels of effort towards achieving a goal in a group setting,
Social Facilitation:
the beneficial effect that being in the presence of others has on the performance of well-learned tasks.
adrenal medulla secretes:

Psychoanalysis:
focus on the unconscious mind in shaping personality.
Schachter-Singer theory of emotion
argues that emotion arises from physiological arousal that is cognitively labeled as a given emotional experience.
James-Lange theory of emotion
states that unique patterns give rise to emotional experiences.
Cannon-Bard theory of emotion
suggests that physiological arousal and emotion occur simultaneously.
Cognitive appraisal theory of emotion
argues that emotional experience depends on the appraisal of the situation in which one presently finds oneself.
availability heuristic
a cognitive strategy used to estimate the likelihood of some given event based on how many instances of such an event come to mind.
Gambler’s fallacy
refers to the erroneous assumption that the probabilities of independent events change because of a string of events that has previously occurred.
Somatic symptom disorder:
is a psychological disorder that involves an individual exhibiting symptoms of physical disease or injury in the absence of the actual disease or injury.

children acquire both conservation and reasoning
Formal operational stage:
children acquire abstract logic.
The Yerkes-Dodson law of social facilitation:
social facilitation: perform better when being observed on simple tasks than complex ones
suggests that optimal performance is associated with an intermediate level of arousal.
Deindividualization:
involves a loss of one’s sense of themselves and personal responsibility when someone is a part of a larger group. This is often associated with a “mob mentality”
Bystander effect:
when help to a victim is withheld in situations in which
there are other people around
Social loafing:
people will exert less effort towards a common group task because others are also engaged in completing the task.
Solomon Asch’s (1952) famous experiment:
Conforming, it was obvious what the right answer was but when the rest of the group was saying the wrong one, the person being observed also said the wrong answer.
Internalization:
The process by which an individual accepts, as his or her own, a set of norms established by people or groups influential to that individual.
Identification:
The process of incorporating the characteristics of a parent or other influential person by adopting their appearance, attitudes, and behavior.
Diff between conformity, compliance, and obedience:
To conform is to passively change behavior based on influence of others, compliance is to change when asked or encouraged by others, and to obey is to change due to a command by some sort of authority figure.
Formal and Informal social control:
Formal: Laws, rules and sanctions enforced by authority figure.
Informal: disapproval such as shame, ridicule, sarcasm or criticism.
Group polarization:
Tendency of groups to make decisions that are more extreme (on either end of a continuum) than would individual members of that group acting alone.
Groupthink:
Tendency of groups to make decisions that are incorrect or illogical based on a desire to maximize group consensus and minimize group conflict.
Irving Janis’ Eight Symptoms of Groupthink:
A. Illusions of invulnerability: The group setting fosters a heightened sense of optimism that can lead to riskier behaviors.
B. Group’s inherent morality: The group setting fosters a belief that the group’s actions are above moral reproach.
C. Group rationalization: Group members do not question assumptions that are being made and ignore any warnings that might deter them from the present course of action.
D. Out-group stereotyping: Group members view those outside of the group as biased, ignorant, and/or morally inferior.
E. Suppression of dissension: Individuals in the group feel pressure not to voice disagreements with the group.
F. Self-censorship: Individuals who may doubt the group do not voice their concerns in the group setting.
G. Illusions of Unanimity: Group members believe that the view of the majority is held by everyone in the group.
H. Mindguards: Group members shield the group from any dissenting information.
Folkways:
rules for casual social interaction. We all have an understanding that we face the front of an elevator. Someone violating this folkway would face the opposite direction and look at the other passengers.
Mores:
are norms that have great moral significance and are widely observed by members of society.
Taboos:
are the most morally significant and even the thought of violation brings about a strong, negative response from members of society.
Sanctions:
are consequences, formal or informal, assigned by members of society as a result of norm violation.
Anomie:
Normlessness; A state of instability due to a lack of social norms, or the breakdown of social standards or values.
Deviance:
▪ Functional Theory: Deviance is not necessarily negative, and is in fact necessary for social
order. Deviance helps clarify the boundaries of social norms. It can also play a positive role in
initiating social change.
▪ Differential Association Theory: Through interaction with others, individuals learn the values,
attitudes, and techniques for deviant behavior, especially criminal behavior.
▪ Labeling Theory: Deviance and conformity result from how others respond to another person’s actions rather than what these others actually do. LABELS
▪ Strain Theory: Conformity, Innovation-reject society to achieve social goals, Ritualism-Reject culture goals but rigidly adhere to societal rules, Retreatism-rejects both, societal dropouts, Rebellion-rejects both but comes up with own versions of both (tea party activists).
Stigma:
extreme dislike or negativity toward a person or group (or some characteristic of that person or group) based on perceived deviance from social norms. For example,
psychologists frequently discuss “the stigma of mental illness.”
Diff between collectives and groups:
collectives are defined as an unplanned activity among a large number of people that may result in social change. It is often controversial. Groups: primary, fam and close friends have most influence. Secondary, EX: an intro college course, is temporary and likely will not be influenced by one another after class ends.
Examples of collective behavior:
Fads, mass hysteria, riots
Socialization:
A lifelong process, beginning in infancy, by which an individual acquires the habits, norms, and beliefs of society. Primary: influence from fam and close friends. Secondary: influence from groups, education, media, religion, etc.
4 Main agents of socialization: (in order)
o The Family
o Mass Media
o Peers
o Workplace
Attribution:
The tendency to infer that the behavior we observe in others can be attributed to specific causes. (Often inaccurate)
Dispositional: behavior attributed to disposition and way of being. (internal locus of control)
Situational: behavior attributed to situation in which it is expressed. (external locus of control).
Collectivist vs individualistic cultures:
Western Cultures = more individualistic = more prone to the Fundamental Attribution Error: (more likely to associate behavior with disposition than situation)
Non-Western Cultures = more collectivist = more prone to make situational attributions.
Social perception:
How we perceive other individuals or groups, form impressions of them, and make judgments about them. Our social perceptions are often inaccurate due to various forms of bias.
Self Serving BIas:
Focusing on strengths, downplaying weaknesses. Examples would include believing that we are more intelligent than we actually are or by blaming personal failures on others.
Confirmation bias:
we tend to overestimate how “right” we are about some particular belief and experience the confirmation bias by seeking out and attending to information that
agrees with our own perspective while ignoring information that would counter our beliefs.
The primacy effect:
is experienced when we recall the first few items in a list more readily than other items. Examples would include remembering the names of the first few people you met at a party better than others
The recency effect:
is experienced when we recall the most
recent items from a list of items better than others. Again, remembering the last few names or
words in a list would or using the most recent interactions to form an impression of a person
would serve as examples.
Just world hypothesis:
is the tendency to believe that people get
what they deserve.
The halo effect:
is a bias by which a positive appraisal in one area will automatically generate positive appraisals in other areas.
Reliance on central traits:
describes how our perceptions of others are affected by focusing on characteristics that are of particular interest to us. So for example, we may have
more positive perceptions of others that show key characteristics that we view positively and
more negative perceptions of people that show key characteristics that we view negatively.
Ethnocentrism:
judging another culture based solely on the values of one’s own culture.
Cultural relativism:
is judging another’s culture by its own standards.
Role conflict:
occurs when there is a clash between the roles associated with two or more statuses
Role strain:
refers to stresses among the roles associated with one particular status. For example, a parent may feel closer to one of their children more so than the others. In order to treat each child fairly, however, the parent must put those feelings aside.
Role exit:
Role exit refers to the process by which people disengage from important social roles
Ainsworth’s strange situation:
In this scenario, the infant is separated from and reunited with their caregivers. The infant’s reactions to each event are video recorded and scored to determine the degree to which the infant is securely attached to their caregiver.
What is umami responsible for detecting in taste?
Amino Acids, protien
Primary group:
long-lasting, close interactions, tight bonds, unlikely to dissolve
Secondary group:
short-lived, superficial, weak bonds, dissolve easily
What are in groups and out groups?
In-groups are those social groups that members feel an affinity for, aloyalty to and a respect for. In contrast, out-groups are those social groups that individuals feel
competition or conflict toward.
Dyad:
smallest possible group; tend to be emotional and unstable; by definition a dyad is dissolved if one person leaves the group; less likely to survive.
Triad:
addition of one person adds stability; disputes often mediated by the third member of the group; more likely to survive (even if becomes a dyad to do so).
Large group:
as group size increases, stability and longevity also increase, but intimacy, loyalty, bonding, sense of responsibility, level of individual contribution, and consensus all decline. Most stable group size.

The Cocktail party Effect:
a specific instance in which we may suddenly shift our attention to something that was previously ignored because of some cue that draws our attention.

Schemas:
are patterns of thought that we use to create categories of information or behavior and to understand the relationship that exists among those categories
