memory - p1 Flashcards
(11 cards)
peterson & peterson
duration of stm
lacks mundane realism
(constant trigram = artifical)
baddeley
coding of ltm
high control over extraneuous variables
miller
capacity of stm
high reliability - controlled environment
bahrick
duration of ltm
high in mundane realism (real life memories of classmates)
low control over extraneous variables (not controlled envirnoment = no cause and effect)
types of ltm
neuroimaging evidence to support diff types of ltm
^ scientific methods
real life evidence - clive wearning case study ( episodic damaged = cant rem musical education but episodic works = can play piano — therefore seperate parts of ltm)
^ low pop val
working memory model
rts - shallice and warrington - patient kf ( diff parts of stm - recall of stm digits poor (phonological loop) = read to , but good = read (visual spatial sketchpad))
^ low pop val
dual task performance studies
( baddeley found hard to do 2 visual tasks (pointer= moving light and mentally move ‘F’
but
easy when one task is verbal (repeat ‘the’)
interference forgetting
rts - mcGeoch & mcDonald ( list a+b, recall accuracy list b = synonyms (12%), antonyms (26%)
^high reliabilty - controlled lab
^lacks mundane realism - learning words = artificial
retrieval failure due to abscene of cues
Context dependent forgetting = rts - Godden & Baddeley (scuba divers list learning in and out of water and recall in same and opposite locations = 40& less accurate in oppsosite)
State dependent forgetting = rts - Goodwin (list learning sober/drunk then recall in same or opposite state 24 hours later
^lacks mundane realism
^prac app - cog interview use contect reinstatement - imagine at scene of crime for more int/ext cues to remmeber = more accurate eye witness testimony
post event discusiion
rts - skagerburg and wright (mugging brown/blonde hair = memory contamination - blend = medium brown haior)
demand characteristics - controlled envirnoemnt + unrealistic task
anxiety
rts - neg effect of anxiety - valentine & mesout (low and high anx in london dungeons and recall physical details of actors - high anx = low accuracy)
rtc - christian & hubinette (58 real witness of bank robbery - 75% more accurate but more accurate the higher anx)
yerkes dodson law - anx + accuracy of ewt is complex, diff levels of anx affect ewt, too much or too little = poor ewt, opitmum = high ewt , explaims diff in results in johnson + scott, ppt in christ = optimum, resolves contradictin and validates anx affect ewt)
cog interview (imp accuracy of ewt)
rts - Kohnken - meta analysis of 50 studies compare cog and standard interview , cog interview had 41% increase in correct info
^ 81% more info collected but often more incorrect info rem(61%) = flase imprisonments ans wasting time
^ neg affect on economy - false inprison, waste time and money, waste tax payer money
