Psych/Soc Flashcards
Conditioned Response
the learned response to a neutral (or conditioned) stimulus
Unconditioned Stimulus
a biologically significant stimulus (food/pain) that elicits an unconditioned response
Aquisition
Process of pairing a neutral/conditioned stimulus with an unconditioned stimulus. The more often this happens, the stronger the conditioned response will be.
Extinction
When an animal no longer produces the conditioned response; occurs when you present the conditioned stimulus without the unconditioned stimulus
Discrimination
When only the conditioned stimulus can elicit the conditioned response and other stimuli cannot
Generalization
tendency to respond in a similar way to similar but different stimuli
Amygdala
Responsible for regulating our perceptions of and reactions to aggression and fear
Chronic stress alters the excitability of neurons in the amygdala, leading to more anger, fear, and anxiety.
Normative Organization
people join due to a shared ethical or ideal goal
Utilitarian Organizations
members are compensated for their involvement
Attributional Bias
a cognitive bias that refers to the systematic errors made when people evaluate or try to find reasons for their own and others’ behaviors– will not always reflect reality
fundamental attribution error.
describes the tendency for individuals to overemphasize internal characteristics, such as personality, in attempting to explain someone’s behavior at the expense of situational factors.
Underemphasizing situational and environmental explanations and overemphasizing dispositional and personality based expectations
Sensory Neurons
transmit info from periphery to CNS
Interneuron
found in the spinal cord
Motor Neurons
carry signals away from the spinal cord and toward the muscle
Construct Validity
whether or not measures actually assess the variables they are intended to assess
External Validity
the extent to which we can generalize results onto different experimental settings or real life situations
Projective Personality Assessments
require the participant to respond, and their response is assessed for meaning
Weber’s Law
There is a linear relationship between the intensity of a stimulus and its detection
Huntington’s disease
caused by an expanded CAG repeat in the gene on chromosome 4
Blocking reuptake of a hormone would
potentiate/ increase its effects

removes a pleasant factor to discourage a behavior
positive punishment
adds an unpleasant consequence to discourage a behavior
kinesthetic system
balance and sense of body in the world
groupthink
occurs when homogenous groups of people have a strong desire for harmony/conformity that they will make irrational decisions!!
Cross-sectional studies
investigate a population at a single point in time, looking for predictive relationships among variables.

Vygotsky’s social learning theory
stresses role of people and interactions in the acquisition of cognitive skills
cognition and language develop independently but are both influenced by social interaction: Cognition is the product of socialization, and language arises out of a necessity for social communication.
Chomsky’s language acquisition theory
People have an innate language acquisition capacity
Erikson’s 8 stages
0-1 : Trust vs. mistrust
1-3 : Autonomy vs. shame/doubt
3-6 : Initiative vs. guilt
6-12 : Industry vs. inferiority
12-20 : Identity vs. role confusion
20-40 : Intimacy vs. isolation
40-65 : Generativity vs. stagnation
65+ : Ego integrity vs. despair
Preconventional stage (Kohlberg)
stage of moral development characterized by more concern for rewards and punishments than social rules and laws
Postconventional stage (Kohlberg)
stage of moral development characterized by concern with morality and the good of society than social rules and laws
N1 sleep stage
Dominated by theta waves.
Strange sensations – hypnagonic hallucinations, hearing or seeing things that aren’t there.
N2 Sleep Stage
deeper stage of sleep. harder to awaken. more theta waves, as well as sleep spindles and K-complexes.
Sleep spindles help inhibit certain perceptions so we maintain a tranquil state during sleep
K-complexes supress cortical arousal and keep you asleep. Also help sleep-based memory consolidation.
N3 sleep stage
slow wave sleep. Characterized by delta waves. Where walking/talking/bedwetting in sleep happens
REM sleep
muscles paralyzed, dreams occur and memories are consolidated
Combination of alpha, beta, and desynchronous waves
Sometimes called paradoxical sleep, because brain is active and awake but body prevents it from doing anything.
Universal emotions
Happiness
Sadness
Contempt
Surprise
Anger
Disgust
Fear
Length of sleep cycle
90 minutes
moderating variable
changes the strength of the relationship between dependent and independent variables
mediating variable
explains the relationship between independent and dependent variables
Affect heuristic
making a judgment based on emotions that are evoked
the context effect
the influence of environmental characteristics on a person’s perception of a stimulus
Social cognitive perspective
emphasizes both thinking and social learning in personality development
ex. person sees violence have positive results and becomes prone to violent behaviors
sexual dimorphism
degree to which males and females resemble each other
high sexual dimorphism= very different, intense competition for mates
stimulus motive
a motive that appears to be unlearned but causes an increase in stimulation
a motive that is driven by external stimuli and the interaction with the environment. So like the idea of discovery and curiosity is a stimulus motive because its something intrinsic we have, we want to learn how the world around us works, but at the same time is not necessary for survival
Stanley Milgram
performed obedience experiment where he demonstrated that participants would follow orders of a superior if instructed to go against their conscience
Informative pressure
a type of conformity pressure; occurs when an individual conforms behavior to match that of the rest of a group because they believe the group is better informed
normative pressure
type of conformity pressure; individual knows the others are incorrect, but still feels pressure to not dissent
James Lange
“action before emotion”
emotions are the result of autonomic arousal
Cannon-Bard
“two bards with one stone”
physiological arousal and subjective experience occur simultaneously
Schachter-Singer
“Sensation (physiological response) and Solve (interpretation of cognition) = emotion
Emotions are based on a stimulus which the mind then puts into context; processing context of stimulus creates the emotion
similar to the James-Lange theory except for an additional component: cognitive interpretation of physiological response. In other words, anger, fear, and excitement might all produce similar elevations in heart rate, but the experience of each emotion is quite different because emotion is the result of two factors, physiological arousal and cognitive interpretation of the situation.
Lazarus
“Lazarus labels first”
Labeling recognition then physiological response and emotion
Limbic System
storage and retrieval of memories that pertain to emotion
HAT Hippo
Hypothalamus
Amygdala
Thalamus

Symbolic interactionism
looks at micro level; how human behavior is the most impactful to society
people act based on meanings of cultural symbols derived from cultural interactions
studies how people interact by using a shared understanding of certain symbols (e.g., a “thumbs up” sign).
Cooley/Mead
Cultural Relativism
beliefs/health behaviors that should be understood within the context of culture
Social desirability bias
when people feel pressured to respond in a way that is socially acceptable within a study
Harlow
Monkey experiment; showed that infants would cling to cloth mother, even when wire mother was the only food provider
showed that contact comfort is crucial
monkeys paired with wire mother behaved abnormally; could not be corrected
anomie
when society feels fragmented and incohesive
Internal Validity
degree to which causal conclusions can be drawn from studies
the extent to which you can assume the intervention being studied caused the observed outcome
face validity
whether an assessment superficially appears to measure what it is supposed to measure.
external validity
how generalizable findings of a study are to the population as a whole
functional MRI
allows researchers to assess the operation of brain regions, as well as their structure
Measures blood oxygenation in the brain
High risk behaviors associated with
prefrontal cortex (nucleus accumbens, amygdala)
(also involved in critical thinking)
Also, chronic stress has been shown to decrease dendritic branching in areas associated with cognitive flexibility within prefrontal cortex, resulting in REDUCED COPING MECHANISMS. It also increases dendritic branching in areas associated with INCREASED HYPERVIGILANCE.
confounding variable
affects both independent and dependent variable, causing them to be related

different than role conflict which stems from two separate roles
role conflict
two roles coming into conflict
alzheimers
reduced acetylcholine
schizophrenia
increased dopamine
korsakoff
decreased thiamine (B1)
Hans Selye
Introduced general adaptation syndrome to describe responses to long and short term stress reactions:
- alarm reaction
- stage of resistance
- stage of exhaustion
an organism’s stress response always follows a similar course, regardless of the exact nature of the stressor
activation synthesis
has to do with differences in neuronal activity in brainstem during waking/resting sleep
theory of cognitive appraisal
explains mental processes that influence responses to stressors
stress as a two step process:
1. production of stressors by environment
2. response of an individual subjected to stressors
house money effect
people don’t think of newly gained money as one’s own and will assume more risk with it
the gambler’s fallacy
if something happens more frequently than normal for a period of time, it will happen less frequently in the future
prisoner’s dilemma
when individual decision makers act in a way that will cause less optimal outcomes for a group
ex. if one person confesses, the other will have better outcome; often neither confess
LGN
relays visual info
Hippocampus
plays a key role in forming new memories. Convert STM (Short term memory (from the past 20 seconds)) to LTM (long term memory). If destroyed, still have old memories intact, just can’t make new ones (anterograde amnesia).
frontal lobe
cognitive skills/judgment/development
Parietal lobe
spatial sense/navigation
General strain theory
individuals with negative experience may behave in negative ways
reciprocal determinism (Bandera)
behavior influences and is influenced by personal factors and environments

negative: something taken away
positive: something given
punishment: to stop a behavior
reinforcement: to promote a behavior
social cognitive theory
people learn by watching others
ideal bureaucracy
impersonal, written rules, hierarchical
Eysenck
We have 3 major dimensions of personality:
extroversion
neuroticism (emotional stability)
psychoticism (degree to which reality is distorted)
not all necessarily have psychoticism.
Allport
3 traits of personality:
cardinal (most important)
central
secondary
Adrenal cortex secretes…
aldosterone
Posterior pituitary secretes…
vasopressin (ADH) for fluid uptake in kidneys
oxytocin
adrenal medulla secretes…
epinephrine and norepinephrine
drive reduction theory
motivation arises from desire to eliminate drives (hunger/reproduction) and depression stems form a reduction in arousal
motivation is the result of a disruption in homeostasis, which produces a physiological need (eg, hunger), which leads to a drive (eg, desire to eat). Homeostasis is reestablished once the drive is reduced.
incidence
number of cases per year
prevalence
of people overall
Types of stress
distress: negative
neustress: neutral
eustress: positive
core components of emotion
physiological arousal (how your body reacts to emotions, emotional information or stimuli)
expressive displays(how you express your emotions)
subjective experiences (how you feel and interpret your emotions, which is extremely personal and subjective).
physiological
cognitive
behavioral
representative heuristic
reasoning about a probability based on a prototypical example/stereotype
availability heuristic
reasoning based on what most easily comes to mind
Asch
studied whether social pressure is likely to make someone conform
age stratification theories
age is a way of regulating a generation’s behavior
Activity Theory - looks at how older generation looks at themselves. Certain activities or jobs lost, those social interactions need to be replaced so elderly can be engaged.
Disengagement Theory – older adults and society separate, assumes they become more self-absorbed as they age. But considers elderly people still involved in society as not adjusting well, which is debatable.
Continuity Theory - people try to maintain same basic structure throughout their lives. As they age make decisions to adapt to external changes and internal changes of aging.
dependency ratio
the proportion of unproductive (ie, too old or too young to work) to productive (ie, working-age) members in a society
Malthusian theory
maintains that population growth is exponential but resource growth is linear.
When populations outgrow available resources, preventive checks decrease the birth rate and positive checks increase the death rate; Malthusian catastrophes are large-scale positive checks (war, disease epidemics).
Optimum population
a demographic theory regarding the ideal population size, which is the number of people yielding the highest per capita income given the country’s level of wealth, knowledge, and technical resources.
Binocular cues
Give sense of depth
Retinal disparity (eyes 2.5 inches apart, get slightly different views of objects)
Convergence- angular position of eyes as they focus (things far away, eyes relax; things close to us, eyes contract)
Monocular cues
depth cues that can be perceived using one eye only and often rely on comparisons between objects
Relative size (closer/bigger)
interposition (overlap)
relative height (things higher perceived to be further away)
shading and contour
motion parrallax (things farther away move slower)
Constancy- our perception doesn’t change even if the image cast on the retina is different (size, shape color)
Sensory adaptation- Inner ear muscle
will contract with prolonged higher noise
sensory adaptation- smell
desensitized to molecules
sensory adaptation- proprioception
sense of the position of the body in space
sensory adaptation- sight
down regulation: light adaptation; when it is bright pupils constrict and become desensitized
up regulation: dark regulation; when it is dark pupils dilate and synthesize light sensitive molecules
absolute threshold of sensation
minimum intensity needed to detect a stimulus 50% of the time
Neuron timing
Non-adapting: neuron consistency fires at a constant rate
Slow adapting: neuron fires at the beginning of a stimulus then calms down
Fast adapting: neuron fires as soon as stimulus starts, then stops
vestibular system
located in inner ear
the sensory system that contributes to balance and the sense of spatial orientation
canal filled with endolymph which detect direction of movement
otolithic organs help detect linear acceleration and head positioning
contains semicircular canals
signal detection theory
looks at how we make decisions under conditions of uncertainty
signals have noise distribution (background) and signal distribution peaks
- d’ is between two peaks
hit, miss, false alarm, correct rejection
d’ = strength
C= strategy (might be liberal or conservative)
if C=0 it is ideal
if C>1 conservative (says no unless positive, will get some misses)
if C <1 liberal ( says yes, will get false alarms)
bottom up processing
begins with stimulus, which influences what we perceive
data driven
top down processing
uses background knowledge and influences perception
theory driven; perception influenced by expectation
Gestalt principles
explains how we perceive things
- similarity: items similar to one another group together by the brain
- pragnanz: reality in its simplest form possible
- proximity: objects close together are grouped together in our minds
- continuity: assume lines follow smoothest path
- closure: objects group together seen as whole
- symmetry
law of common fate: objects functioning/moving in same direction perceived to belong together (flock of birds)
law of past experiences: ex. even if you see a new word for the first time, know that Li is two separate letters, not a U
conjunctiva

cornea
transparent, thick sheet of fibrous tissue; starts to bend light; first part that light hits
outermost layer of the front of the eye, in which it directly contacts the back of the eyelids
anterior chamber

pupil
modulates the amount of light able to enter the eyeball
iris
gives he eye color; constricts/relaxes to change size of pupil
lens
changes shape and uses suspensory ligaments to bend the light so it goes to the back of the eyeball; focuses light on the fovea of the retina
suspensory ligaments
attached to ciliary muscle to form ciliary body which secretes aqueous humor
posterior chamber
area behind the iris to the back of the lens; filled with aqueous humor
vitreous chamber
filled with vitreous humor; provides pressure and gives nutrients to eyeball
