- 1Baddely, Thomson and Buchanan (case study)-visual presentations of word lists
-brief exposures
-serial order
-CONDITION 1 -one syllable words
-CONDITION 2- polysyllabic words
-several trials
-shorter words were easier to recall
-word length affect
-repeated measures design - 2Shepard and Feng (case study)evidence for visuo-spatial sketchpad
box net experiment
imagine folding,- answer whether the arrows joined or not
time was same as if actually folded
visual images work in similar ways to real life perception - 3evidence for the central executiveBaddeley investigated selective attention and switching retrieval plans
participants had to generate random strings of digits
this was carried out simultaneously reciting the alphabet/counting/alternating between letters and numbers
generated string was less random in COND 3, random generation and alternation were competing for the same central executive resources - 4strengths of the working memory modelextremely influential
apply to previous research, digit span, acoustic confusion
Baddely- phonological loop not active in people with dyslexia
it can account for individual differences - Turner & Engle - 5weaknesses of the working memory modeldoes not offer a complete understanding of how memory works
Berz- fails to account for musical memory
Cowan-should have some long-term memory activation for text comprehension - 6What is an inference taska task that gets in the way of the processing necessary to do the task being tested
- 7What is subvocal repition?repeating something 'under your breath' or mentally so its not said out loud
- 8what is articulatory supression?a participant is given a task that would usually make use of the articulatory loop but they are asked to simultaneously repeat a meaningless chant e.g la-la-la
- 9What did Baddeley find about Articulatory Suppression?word length effect disappeared.
the advantage in recalling short over long words depends on having a verbal rehearsal system
if this is filled up with irrelevant material then short/long words are processed elsewhere - 10What is a dual task method?where participants are asked to carry out a primary task whilst also engaging in a secondary task.
Performance is then compared to when the tasks are done seperately
