AO3 - Working Memory Model

• The WMM provides an explanation for dual tasks/ processing.
• Shallice & Warrington (1970) reported that brain-damaged patient K.F could recall visual but not verbal information immediately after its presentation. This supports the WMM.
• The WMM was developed based on evidence from lab experiments, so variables could be carefully controlled to produce reliable results.
• WMM has been criticised for being too simplistic and vague, e.g. it is unclear what the central executive is, or its exact role in attention.
• Laboratory experiments researching the WMM have low ecological validity.
• Shallice & Warrington (1970) support the WMM and the existence of separate visual and acoustic stores.
• Much of the supporting evidence for the WMM was conducted by Baddeley himself, which is subjective.
• Baddeley (1975) offered support for the WMM using dual task experiments, showing when both tasks are visual or both are verbal, performance declines.
