magnitude between two stimuli before one can perceive this difference
weber’s law states that
JND (just noticeable difference) for a stimulus is proportional to the magnitude of the stimulus
signal detection theory refers to the effects of
nonsensory factors such as experiences, motives and expectations on the perception of stimuli
accounts for response bias

proximity
similarity
continuity
closure
all governed by law of pragnanz
habituation is
becoming used to a stimulus
dishabituation occurs when a
second stimulus intervenes causing a resensitization of original stimulus
associative learning is the pairing together of
stimuli and responses/behaviors and consequences
operant condition is changing behavior through
use of consequences
reinforcement increases
likelihood of behavior
punishment decreases
likelihood of behavior
schedule of reinforcement can be based on
an amt of time or ration of behavior/reward
fixed or variable
positive response (does what) something
adds
negative response (does what) something
removes
extinction is when
a previously reinforced behavior disappears when no longer reinforced
shaping occurs when a behavior that is
closer and closer to the target behavior is reinforced
part of operant condition
with repetition, a neutral stimulus becomes a condition stimulus in
classical conditioning
conditioned response produced
observational learning is the
acquisition of behavior by watching others
encoding is the process of putting
new info into memory
can be automatic or deliberate
what type of encoding is strongest
semantic encoding > visual and acoustic encoding
memory that is transient and based on neurotransmitter activity
sensory and short term memory
working memory requires
short term memory, attention and executive function to manipulate info
long term memory requires elaborate rehearsal and is the result of
increased neuronal connectivity
explicit memory accounts for memories that we must
consciously recall w/ effort and focus
implicit memory accounts for
acquired skills and conditioned responses to circumstances/stimuli
semantic networks store
facts
concepts are linked together based on
similar meaning in semantic networks
certain triggers will
activate associated memories
in semantic networks
recognition of info is stronger than
recall
retrieval is based on
priming interconnected nodes of the semantic network
what causes alzheimer’s
linked to loss of acetylcholine in neurons that link to hippocampus
causes dementia and memory loss
korsakoff’s syndrome is caused by
thiamine deficiency in brain
retrograde and anterograde amnesia are caused
confabulation is the fabrication of
vivid but fake memories as part of a korsakoff’s syndrome
agnosia is the loss of
ability to recognize objects, people or sounds
what is agnosia usually caused by
physical damage
retroactive interference is when
new memories make you forget old ones
proactive interference is when
old memories interfere with making new ones

mesolimbic pathway
selective attention allows one to pay attention to
a particular stimulus while determining if additional stimuli in background require attention
divided attention uses
automatic processing to pay attention multiple activities at one time
purpose behind our actions is called
motivation
motivation can be
extrinsic and intrinsic
instincts are innate patterns of
behavior in response to stimuli
instinct theory is when people perform
certain behaviors b/c of evolutionarily programmed instincts
the state of being awake and reactive to stimuli is called
arousal
optimal arousal theory states that
optimal performance requires optimal arousal
arousal levels that are too low or high will
impede performance
internal states of tension that beget particular behaviors focused on goals is called
DRIVES
primary drives are related to
biological processes
secondary drives stem from
learning
drive reduction theory states that motivation arises from the desire to
eliminate drives, creating uncomfortable internal states
maslow’s hierarchy of needs
triangle that shows physiological needs make up base and self-actualization at the top
self-actualization is the
full realization of one’s talents and potential
self-determination theory emphasizes
three universal needs
autonomy, competence, relatedness
incentive theory explains motivation as the
desire to pursue rewards and avoid punishments
expectancy-value theory explains the amount of motivation for a task is based on
the expectation of success and value of that success
opponent-process theory explains motivation for drug use:
as drug use increases, body counteracts effects
opponent-process theory leads to
tolerance and uncomfortable withdrawal symptoms
house money effect states that
after a prior gain, people become more open to assuming risk
since new money is not treated as one’s own
gambler’s fallacy states that if something happens more frequently than normal…
i.t. will happen less frequently in the future or vice versa
prisoner’s dilemma states that two people act out of their own…
self-interest but if they had cooperated, result would be better
stress is the physiological and cognitive response to
challenges / life changes
primary appraisal is
classifying a potential stressor as irrelevant, benign-positive or stressful
secondary appraisal is the
evaluation if organism can cope w/ stress
anything that leads to a stress response is a
stressor
stressor can lead to
distress or eustress
3 stages of stress
alarm
resistance
exhaustion
involve both sympathetic NS and endocrine system
release of ACTH leads to
increased cortisol
emotion is a state of mind or feeling that is
subjectively experienced based on circumstances/mood/relationships

happiness
sadness
contempt
surprise
fear
disgust
anger
james-lange theory is when
behavioral and physiological actions lead to emotions
e.g. power posing
cannon-bard theory is when
emotional and physiological responses to a stimulus occur simultaneously
emotional and physiological responses arrive from
separate and independent areas of brain as a part of the cannon-bard theory
schacter-singer theory explains the
two factor emotion theory
physiological arousal and interpretation of context (or “cognitive label”) leads to emotion
limbic system is concerned with
insticnts and mood
self-concept is the sum of ways…
we describe ourselves
identities is the individual components of our
self concept related to the group to which we belong
self-esteem is how closer our ACTUAL self is
to our IDEAL self and our OUGHT self (who others want to be)
self-efficacy is the degree to which we see ourselves as
being capable at a given skill or situation
learned helplessness is a state of
hopelessness resulting from being able to avoid repeated negative stimuli
internal locus of control
we control our own success/failure
external locus of control
outside factors have more control
psychosexual stages of personality development is based on
tensions caused by the libido
failure at any stages of the psychosexual stages of personality development leads to
personality disorder
freud’s psychosexual stages of personal development
0 –> 1 ORAL
1 –> 3 ANAL
3 –> 6 PHALLIC
6 –> puberty LATENT
puberty –> adult GENITAL
erikson’s stages stem from
conflicts throughout life
erikson’s stages
0 –> 1 trust vs. mistrust
1 –> 3 autonomy vs shame
3 –> 6 initiative vs guilt
6 –> 12 industry vs inferiority
12 –> 20 indeitity vs role confusion
20 –> 40 intimacy vs isolation
40 –> 65 generativity vs stagnation
65 –> death integrity vs despair
kohlberg’s stages are based on
moral dilemma
6 stages in 3 phases

a child has not yet mastered and require a more knowledgeable other to accomplish
imitation and role-taking are the
common ways children learn from others
reference group is the group to which
we compare ourselves
psychoanalytic perspective are personality results from
unconscious urges and desires
freud, jung, adler, horney

base urges of survival and reproduction
part of freud’s theory
superego is the
idealist and perfectionist
part of freud’s theory
ego is the
mediator between the two and the conscious mind
part of freud’s theory
the ego uses what to reduce stress
defense mechanisms
id, superego, ego operate in the
unconscious
at least in part
jung states that the
collective unconscious links all humans together
personality is influenced by
archetypes
as per JUNG
adler and horney states that the unconscious is
motivated by social urges
humanistic perspective emphasizes the internal feelings of
healthy individuals as they strive for happiness and self-realization
what flow from the humanistic view of personality
maslow’s hierarchy of needs
rogers’s unconditional positive regard flow
type and trait theory states that personality can be
described by identifiable traits that carry characteristic behaviors
type theories include
ancient greek humors
sheldon’s somatotypes
divisions into type A and type B
Myer’s Brigg’s type inventory
