Strengths of WMM

• Case studies: KF had brain damage and could only remember 2 auditory digits but visual memory worked normally in STM
• Paulesu et al. (1993): Used PET scan, Broca’s area activated during subvocal rehearsal task to remember words and supramarginal gyrus active when phonological store was used; supports idea phonological store and articulatory rehearsal system are separate things within the phonological loop slave system
• Lab experiments show participants struggle with simultaneous verbal and visual tasks, aiding in identifying deficits in their WM and strategies to overcome these Baddeley
• Baddeley and Hitch (1976): Dual-Task Procedure: Completed two tasks simultaneously using the same or different memory stores; tasks involved tracking a moving light on a screen whilst imagining the letter F, performance was not impaired when performing one visual task and a verbal task simultaneously, as the visuospatial sketchpad was used for one task and the phonological loop for the other
