Evaluation of WMM

Question 1

outline the research evidence for the WMM

Answer 1

• dual task performance > VSS and PL are separate
• case study > VSS and PL are separate
• biological evidence for the epsiodic buffer
• evidence for capacity of PL

Question 2

outline Baddeleys procedure for dual task performance

Answer 2

• Participants were asked to either perform two visual tasks at the same time or perform a visual and verbal task at the same time

Question 3

what conclusions can be drawn from Baddeleys dual task performance study and why

Answer 3

that the VSS and PL are two different subsystems because the particpants that did two visual tasks at the same time didn’t perform as well as the particpants completing two different tasks

Question 4

how does the case of KF prove that the PL and VSS are different stores

Answer 4

KF has issues with his verbal short term memory but his visual short term memory is unaffected

Question 5

what are the limitations of the WMM

Answer 5

• psychologists believe that this model is vague and doesn’t provide a full explanation of its function
• the research lacks external validity > not realistic
• the model relies on inferences / educated guesses
