Clinical Evidence to support WMM P: The KF Case Study supports the Working Memory Model. E: KF suffered brain damage from a motorcycle accident that damaged his short-term memory. E: KF's impairment was mainly for verbal information - his memory for visual information was largely unaffected. L: This shows that there are separate STM components for visual information (VSS) and verbal information (phonological loop), supporting the model that. However…

Lack of Clarity over the central executive P: Cognitive psychologists criticise the central executive, suggesting it doesn’t really explain anything. E: Baddeley said himself ‘the central executive is the most important but least understood component of working memory’ E: the central executive needs to be clearly specified, some psychologists claim that it may consist of separate components. L:This means the WMM hasn’t been fully explained.

A better insight into Memory than the MSM P: The working memory model has many strengths over the multi-store model. E: It describes short term memory as a collection of active processing mechanisms that work in two modalities (verbal and visual) rather than a single store that simply rehearses verbal information. E: This allows it to explain memory function in patients with impairments to one component of working memory but with normal function in the other components, such as KF. L: therefore increasing our understanding of memory as an active process rather than a passive process as the MSM suggests.
