5 - intro to psych - memory

what is memory

storage of info

what is the process theory of memory

encoding - storage - retreival

can be studied through recall and recognition

what does the level of processing depend on

nature of the stimulus

time available for processing

what are the levels of processing

shallow - visual

medium - phonetic

deep - semantic

however no defition of what shallow and deep processing is

what is the duel store memory model

rehearsal of info means more likely to remember - strengthens

stort term memory boots out older info to replace w new

atkinson and shiffrin

what is the capacity duration and coding of stm

capacity - 7+-2

duration - less than 18 seconds

coding - a range

what is the serial position effect

youre more likely to remember irst and last bits of information more likley to forget middle

primary-recentcy effect

what ae the 2 types of ltm

procedural - implicit - often unconsious

declaritive - facts - episodic semantic - often conscious

what ae the two reasons for forgetting

availability - whether info has been stored

accessability - whether info can be retreived

what is decay theory

in ltm- memorys are structral changes in the brain

over time engams egrade without rehearsal

what is displacement theory

in stm - when new info comes in old is replaced

what is cue rependant forgetting and retreival failure theory

tip of the tongue phenomena

cant receive cues either interal or external

what is interference theory

when previous or later learning interferers with recall - either proactive or retroactive

how is sleep important in recall

decay cannot be based on time alone

other factors at play

memory is enhanced after a nights sleep

less impact on proceduaral memory
