Exam 2 Flashcards
distal stimulus
physical object
proximal stimulus
optical image on the retina
absolute threshold
minimal stimulus detectable
difference threshold
minimal change in a stimulus detectable
Weber’s law
bigger stimulus = bigger change to be detectable
accomodation
ciliary muscles change thickness of the lens to adjust to see near/far
vestibular sense
body orientation relative to gravity
Gestalt Psychology
the whole is greater than the sum of it’s parts
bottom-up processing
perceptual analysis based on what you see
top-down processing
perceptual analysis based on previous knowledge
set
temporary readiness to perceive/react to a stimulus in a certain way
phonemic restoration
“hearing” what wasn’t actually heard when a part is obscured
law of proximity
group together what is close
law of similarity
group together what is similar
law of good continuation
lines are perceived as continuous
law of common fate
group together objects moving in the same direction
autonomic nervous system
prepares the body for emotional responses
sympathetic response
mild, bad
parasympathetic response
mild, good
James-Lange Theory of Emotion
stimulus > ANS > emotion
Cannon-Bard Theory of Emotion
stimulus > ANS & emotion
Cognitive Appraisal Theory of Emotion
stimulus > ANS & cognitive appraisal > emotion
positive mood (approach)
broadens focus, flexible, creative problem solving
negative mood (approach)
harsher judgment (less gullible), focus on critical information
hypothalamus
stress, controls ANS, activates pituitary gland, fight/flight
problem-directed coping
direct actions, problem-solving strategies
emotion-focused coping
make yourself feel better, focus on self not problem
stress inoculation
preparation > confrontation > coping > reinforcement
general adaptation syndrome
alarm recognition > resistance, exhaustion
type A personality
hostile traits, increased risk of illness
burnout
emotional exhaustion, depersonalization, reduced personal accomplishment
sensation seeking
more likely to engage in risky behaviors
explicit memory
takes a conscious effort
implicit memory
no conscious effort
declarative memory
facts and events
procedural memory
how things are done (muscle memory)
iconic memory
sensory memory, visual, brief
working memory
reasoning and language comprehension
phonological loop
rehearsing in your head
visuospatial sketchpad
forming a mental image
central executive
distributes attention to different aspects of a task
episodic buffer
retrieve information from long-term memory and combine it with information from the current context
episodic memory
long-term, autobiographical event and it’s context
semantic memory
generic, categorical, meaning of words and concepts
transfer-appropriate processing
memory is best when encoded and retrieved in the same way
proactive interference
past memories make encoding/retrieving new information difficult
retroactive interference
formation of new memories makes retrieving old ones more difficult
method of Loci
associate items with locations on a familiar path
distortions of reconstructive memory
leveling (simplifying), sharpening (overemphasizing), assimilating (changing details to “fit better”)
engram
physical memory representation
cerebellum
procedural memory, memories acquired by repetition
straitum
habit formation, stimulus response connections
cerebral cortex
sensory memory, sensory associations
hippocampus
declarative memory, consolidation of spatial memories
amygdala
formation/retrieval of memories, emotional connection
sensorimotor (Jean Piaget)
0-2, object permanence, starts symbolic thought
preoperational (Jean Piaget)
2-7, egocentrism and centration
concrete operations (Jean Piaget)
7-11, understanding of conservation, can reason with visual representations
formal operations (Jean Piaget)
11+, abstract reasoning, hypothetical thinking
Erik Erikson’s psychosocial stages
0-1: trust vs. mistrust 1-3: autonomy vs. self-doubt 3-6: initiative vs. guilt 6-adolescence: competence vs. inferiority adolescence: identity vs. role confusion young adult: intimacy vs. isolation adult: generativity vs. stagnation elderly: ego integrity vs. despair
John Bowlby attachment theory
humans are predisposed to form attachments
permissive parent
high response, low demand
uninvolved parent
low response, low demand
authoritarian parent
low response, high demand
authoritative parent
high response, high demand
