Working Memory Model - Evaluation Flashcards
What evidence supports the existence of separate systems in WMM from the case of amnesia patient K.F?
According to Shallice and Warrington, K.F had poor STM for verbal information but good STM for visual information
This suggests that the phonological loop was damaged while the visuo-spatial sketchpad remained intact.
What is the dual-task performance phenomenon in WMM as a strength of WMM?
Doing two tasks at the same time, supports the separate existence of visuo-spatial sketchpad
Two visual tasks are harder than one visual and one verbal task as it’s using one system instead of the two
What is the word length effect as suggested by Baddeley et al as a strength of WMM?
It is harder to remember a list of long words than short words
When given tasks that involve CE, participants use the left prefrontal cortex (PFC). As the task gets harder, activity in PFC increases.
What is a limitation of WMM in relation to the use of clinical cases?
Always handle them with caution
K.F could have had other cognitive impairments due to trauma of his accident which might have affected his performance
What is another limitation of WMM related to baddeley?
Baddeley himself isn’t satisfied with the explanation of CE
Describes it as the most important but least understood part of the model that needs to be researched further
