A strength of WMM is that the case of KF supports separate STM stores. |
SHALLICE & WARRINGTON (1970): studied case of KF who had poor STM ability for verbal information but could process visual information normally. THEREFORE, suggests separate visual and acoustic stores. HOWEVER, evidence from brain-damaged patients may be unreliable. |
|
|
A Strength is that dual task performance studies support the VSS. |
BEDDELEY et al (1975): found participants had more difficulty doing two visual tasks than doing a visual and verbal task at the same time. -both visual tasks compete for same limited resources THEREFORE, dual task performance activity provides evidence for existence of VSS (MSM can't explain this). |
|
|
A limitation of the WMM is a lack of clarity over the central executive, |
COGNITIVE PSYCHOLOGISTS: suggests CE is unsatisfactory, should be more clearly specified that just 'attention' THEREFORE, WMM hasn't been fully explained. |
|
|
A strength is that the word length effect supports the phonological loop. |
BADDELEY et al (1975): found people have mroe difficulty learning a long list of words than short words - limited space in articulatory process for rehearsal THEREFORE, word length disappears in a repetitive task, demonstrating process. |
|
|
A strength is support from brain scanning studies. |
BRAVER et al (1997): participants did tasks involving CE while having brain scan (showed activity in prefrontal cortex) - activity in PC increased as task got harder THEREFORE, study provides evidence that the CE may have a physical reality in the brain. |
