1
Q
Who discovered the duration of Sensory memory? And when?
A
George sperling (1960) and Walsh and Thompson
2
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
What were the findings of Sperling’s experiment?

- When asked to recall the whole thing, participants on average only recalled 5/12 items (42%).
- In the partial report, participants recalled on average 3/4 items (75%).

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, however he could no longer form new LTM.
- However, he performed well on immediate tasks/tests showing his STM was still intact.
5
Q
What is the problem with the case study of HM?
A
It has poor population validity, it does not represent the wider population.
