Q

What was the procedure of Sperling’s experiment?

A
  • Participants saw a grid of digits and letters for 50 milliseconds (0.05 seconds).
  • They were asked to write down all 12 items or in the partial experiment they would hear a tone immediately after the exposure and be told to write down either the top, bottom or middle row.

Q

Who was HM?

A
  • HM (Henry molasain) underwent brain surgery to relieve his epilepsy
  • However, some of his hippocampus was accidently removed from both sides of his brain
  • HM was able to remember previous experiences from his childhood, however he could no longer form new LTM and was unable to recall past events from 11 years ago.
  • However, he performed well on immediate tasks/tests showing his STM was still intact.

What is the problem with the case study of HM?

A

It has poor population validity, it does not represent the wider population.

Q

How does clive wearing support the theory of the MSM?

A
  • Clive Wearing could still use his STM to remember things for about 20 seconds but then he would
    forget everything - he could not form new LTMs
  • The Multi Store Model can be applied to his case, because it suggests an inability to rehearse information into LTM.
