Working memory model evaluation

Strength of dual tasks

Baddeley and hitch found that when two tracks requires the participants to use their phonological loop their ability to perform the tasks are impaired

However when one task requires the particpant to use their phonological loop, remembering a series of numbers,and the other requires their Visio-spatial sketch pad, copying a drawing, their ability was not impaired

This provides support to the model and to the e science of multiple components with =in our short term memory.

Support from patient KF

Motorbike accident

Could recall information stored in LTM but has issues with STM

He could remember visual information but unable to remember sounds

This suggests that there are at least two components within the short term memory system, one component for visual(visual-sketch pad) and another for auditory information (phonological loop). Supporting the WMM

Limitation is that it only focuses on short term memory

No information on the sensory register or long term memory so limits application to everyday human memory and is unable to explain how information arrives into our working memory and how it is stored in our LTM
