Exam 3 Flashcards
Memory stages
encoding, consolidation, retrieval
encoding
code and put into memory, acoustic, visual, sematic
consolidation
maintain in memory
retrieval
recover from memory
sensory memory
briefly holds info for processing, large capacity, about 2 seconds (less for eyes, more for ears), attended STM
immediate memory
stores info for limited time or while manipulating info, 3-5 capacity (from 5-9 or 7 give or take 2), 12-30 seconds w/out rehearsal, attention/rehearsal LTM
working memory
part of STM, when you do thing to what is in your short-term memory
long term memory
what we usually think of as memory, stores information for very long periods of time, very larger storage
part of LTM
- semantic
- episodic
- procedural
a. explicit
b. implicit
semantic ltm
I know that (fact)
episodic ltm
I remember when (episode of life)
procedural ltm
I can do (skill)
- explicit = intentionally try to remember, consciously aware of doing
- implicit = unintentional recognition and influences, priming
rehearsal
The process of repeating information to yourself, helping you “re-hear” the information over again
chunking
A process of arranging information into compact meaningful “chunks” so that they can be more easily rehearsed in immediate memory
ways to improve memory
- rehearsal
- chunking
encoding strategies
massed practice, spacing effect, mnemonics
mnemonic
the study and development of systems for improving and assisting the memory
massed practice
repeated exposure to or study of to-be-remembered information over a very short period of time or without gaps between repetitions
spacing effect
learning is most robust when repeated exposure to or study of to-be-remembered material occurs over a longer timeframe
working memory model
Baddeley
•Specific model of immediate memory
•Central executive = attention
a.Phonological loop = inner voice, stores and manipulates verbal information
b.Episodic buffer = temporary store, link info of visual and verbal
c.Visuospatial sketchpad = inner eye
maintenance rehearsal
shallow, repetition, good for short term, not LTM
elaborative rehearsal
deep, relating new info to old info and memory, mnemonics
kay aspects of memory retrieval
- cues
- free recall
- cued recall
cues
pieces of information in the present that help us remember events from the past, and they are central to remembering
free recall
Remembering previously-learned information without any other context to aid in remembering
cued recall
Remembering previously-learned information with the aid of a clue or information that helps provide context
memory errors
- omission
- commision
- the seven sins of memory
omission
memory errors where info can’t be brought to mind
- Transience
- Absent-mindedness
- Blocking
transcience omission
memories fade, interference theory of forgetting
a. Retroactive interference = new replace olf
b. Proactive = old block new
absent-mindedness omission
not paying attention memory failure
blocking omission
failure to retrieve info available, not enough cues
misattribution commission
deja vu
suggestibility commision
misinformation effect
bias commission
use of schemas
persistence commission
PTSD
misinformation effects
Occurs when incorrect information obtained after an event contaminates our memory of that event
priming effect
introduction of one stimulus influences how people respond to a subsequent stimulus
amnesia
Memory loss due to physical damage or problems in the brain
anterograde amnesia
inability to encode new information into long-term memory
retrograde amnesia
loss of memories prior to a specific traumatic event
HM and the hippocampus
- Had both retrograde and anterograde amnesia
- Gave info of how memory systems organized
- Hippocampus was removed to treat seizures
- Could rehease to remember info
- Gave evidence between immediate and LTM and procedural and semantic
exercise influence on memory
increase B flow to brain, increase neurogenesis in hippocampus to support memory
contact sports influence on memory
harmful, temporary effect on memory
sleep influence on memroy
brain transfers memories from STM to LTM and new synaptic buds form
stress influence on memory
release cortisol impair hippocampus
attribution theory
• When making sense of other’s behavior, we can attribute their behavior to either internal or external causes
- dispositional
- situational
disposition causes
internal, trait-based causes (doesn’t care, usually for others)
situational causes
external, environmental/situational causes (traffic, usually for ourselves)
kelley’s covariation model
Factors help make judgement about behavior, takes time to form
factors of kelley’s covariation model
- consistency = how often
- distinctiveness = in what situations
- consensus = in relation to others
fundamental attribution error
overestimating the impact of internal attribution of an individual’s behavior
- others = things are internal
- us = self-serving bias
actor-observer bias
the actions of others are determined by internal
• Self external
• Others internal
self-serving bias
tendency to make internal or external attributions for one’s behavior in a way that benefits ourselves
• Success -> internal
• Failure -> external
first impressions
made quickly, enduring, seconds to minutes
primacy effect
remember things that come first, why it’s hard to change
confirmation bias
enforce first impression
- Info consistent with beliefs → attention to info that supports beliefs
- Info NOT consistent with beliefs → info is ignored
self-fulfilling prophecy
sociological term used to describe a prediction that causes itself to become true. Therefore, the process by which a person’s expectations about someone can lead to that someone behaving in ways which confirm the expectations
- Other’s beliefs about you -> cause -> other’s actions towards you → reinforce → your beliefs about yourself → influence → your actions → impact → other’s
- Circle
pygmalion effect
if someone expects you to behave in a certain way, you start acting like that
social norms
learned cultural rules, vary across context, culture, and time
social influence
how the presence of other people influence your behavior, feelings, and thoughts
3 levels of social influence
- obedience
- compliance
- conformity
obedience
changing behavior in response to a demand from an authority figure, most strength of social influence
compliance
change way we act/behave because someone asked us to
conformity
change behavior in response to real/imagined pressure from others, least strength of social influence
injuctive norms
how people SHOULD behave
descriptive norms
how people ACTUALLY behave
Asch’s conformity study
- 3 confederates that chose clearly wrong answers
- 35% participants conform with errors
- 75% conformed at least once
- Informational influence = think others know better than you, so you rely on their perceived accuracy to guide your own decisions
group think
psychological phenomenon that occurs within a group of people in which the desire for harmony or conformity in the group results in an irrational or dysfunctional decision-making outcome
3 factors contributing to group think
- Overestimating the group (perceived invulnerability, inherent morality)
- Close-mindedness (divergent thinking discouraged)
- Pressure for uniformity (challenger space)
milgram experiment
- The effects of punishment on memory
- Word pair memorization task
- Teacher gives shock for wrong answers, learner is confederate with heart condition
factors influencing milgram experiment outcomes
- Informational (think other’s know more) and normative influence (want to be liked)
- Responsibility and self-justification
- Procedural details (gradual increase)
how nazi germany inspired milgram study and results
- Wanted to see if “normal” people would give deadly shocks to innocent victims after orders
- Was a lot higher than expected/more people did it than they thought
stanford experiment
- Guards became controlling and fit into their roles in a short amount of time
- Prisoners became difficult, caused problems, and felt mistreated in a short amount of time
- Both prisoners and guards engaged in behaviors appropriate to their roles
