- Working Memory Model (strengths and weaknesses)
- Weaknesses
- exact role played by the central executive remains slightly unclear
- other researchers have questioned whether it can be a single component or whether there are separate verbal and spatial working memory systems
- doesn't offer a complete understanding of how memory works
- exact role played by the central executive remains slightly unclear
- Strengths
- Explanatory power
- WMM explains a number of research findings that can't be explained by the MSM e.g. word length effect
- Baddeley and Hitch conducted a lab experiment
- demonstrated that performance was SLOWER when pp's were given a task involving the central executive and a second task involving both the central executive and articulatory loop, than the articulatory loop alone or no extra task
- evidence supporting phonological loop
- baddeley et al. conducted a lab experiment
- demonstrated that the phonological loop holds the amount of info that can be said in 2 secs
- however, word-length effect disappears if a person is given an articulatory suppression task
- demonstrated that the phonological loop holds the amount of info that can be said in 2 secs
- baddeley et al. conducted a lab experiment
- Explanatory power
- Weaknesses
