Chapter 3: Memory Flashcards
how does memory influence thinking?
- refer to prior knowledge when making decisions/predictions
- use it to solve problems
- use it to assess situations
- use heuristics
availability heuristic
- ppl generally make judgements & decisions on the basis of the relevant memories they retrieve
- easier to retrieve = more likely to based judgement on it
- most of the time it produces useful & correct evidence
representativeness heuristic
- cognitive shortcut to judge likelihood of event based on how similar it is to prototype in mind
memory function (3)
- encoding
- memory storage
- memory retrieval
working memory model - Baddely & Hitch (4)
- central executive
- visuospatial sketchpad
- episodic buffer
- phonological loop
sensory memory
- very short term memory for sensory information before any cognitive processing
short term memory
- refers to the memory that is active & conscious processing
task switching
- switching attention from one behaviour to another
long term memory
- memory that is stored w no particular limit on their duration
declarative memory
- memory that one can declare the existence of
2 kinds of declarative memory
- semantic memory
- episodic memory
semantic memory
- memory for known facts
episodic memory
- memory for events that are personally relevant
non-declarative memory
- memory for things that are difficult or impossible to declare the existence of
2 kinds of non-declarative memory
- procedural memory
- motor memory
procedural memory
- being able to recall how to write your name or how to ride a bike
motor memory
- form of memory in which the recall is correctly carrying out a motor action
shallow processing
- information is processed at sensory & surface level
deep processing
- information processed in terms of semantics & meaning
Schacter’s 7 sins of memory
- transience
- absent mindedness
- blocking
- misattribution
- suggestibility
- bias
- persistence
transience (7 sins of memory)
- everyday memory failures
- lose access to information over time
absent mindedness (7 sins of memory)
- everyday memory errors
- person fails to encode a memory b/c they were distracted
blocking (7 sins of memory)
- temporary retrieval failure
- can be due to spreading activation in semantic memory network
- tip-of-the-tongue
misattribution (7 sins of memory)
- arises from highly associated aspects of semantic networks
- you remember the facts correctly but NOT the source
suggestibility (7 sins of memory)
- arises from highly associated aspects of semantic networks
- incorporate information provided by others into your own recollection
bias (7 sins of memory)
- reflect our own intuitions about memories
- trust our memories & show bias towards them
persistence (7 sins of memory)
- reflect our own intuitions about memories
- memories that linger & persist to psychological detriment of person
eyewitness memory errors
- misinformation effect
- words used can influence their accounts of the events
DRM false memory test
- Ps are presented w list of words they are to remember
- ppl overestimated seeing ‘sleep’ in 1st list b/c it is highly associated w other words but not presented
