evaluation of working memory mode

Question 1

one strength clinical evidence

Answer 1

CLINICAL EVIDENCE

• Shallic and Warrington found that a patient suffered from brain damage
• they found that the patient had poor STM ability for verbal information but could process visual information normally- CASE OF KF
• this suggests that only his phonological loop had been damaged which supports the existence of a separate visual and acoustic store

Question 2

one strength dual task performance

Answer 2

• supports evidence of separate existence of visuo-spatial sketchpad (therefore provided validity which MSM lacks)
• Baddeley showed participants had more difficulty doing two visual tasks then doing both a visual and verbal task at the same time
• this increased difficulty because both visual tasks were completed by the same slave system but when you are doing a verbal and visual tasks simultaneously there is no competition which means there must be a separate slave system that processes visual input

Question 3

weakness

Answer 3

• lack of clarity over the central executive
• Little is known about the central executive, it’s not clear how it works, what it does, it’s not just an attentional process therefore lacks integrity
• understanding of this is very vague and some psychologist believe that this may include multiple components- For example a researcher found a patient named EVR with central executive damage following a brain tumour being moved found had good verbal reasoning but poor decision-making skills

Question 4

limitation of BOTH WMM AND MSM

Answer 4

machine reductionism, doesn’t look at holistic factors and memory in everyday life
