WMM (BADDLEY AND HITCH)

What components does the WMM consist of

• the central executive= a limited capacity component for general processing and controls the two slave systems

• The phonological loop= a temporary storage component for verbal information

• The visuospatial sketchpad= a temporary storage component for spatial AND verbal information

The phonological loop can explain the phonological similarity effect how?

• because it’s more difficult to remember similar sounding that different sounding

• BUT THIS DOES NIT GO FOR SEMANTIC ENCODING (meaning similarity)

• This demonstrates that the phonological loop encodes acoustically

EVALUATION OF THE WMM

• strength= application to alzheimers

  Alzheimer’s has shown decrease functioning in the central executive, when BADDELEY did a experiment with dual tasks he tested it with Alzheimer’s patients as well, the Alzheimer’s group showed impairment when doing visual and verbal task together , coring to BADDELEY it’s because the central executive could not coordinate the two subsystems
