Q

AIMS

A
  1. To investigate the effects of brain damage on semantic memory
  2. To test the relationship between semantic test scores and temporal lobe damage
  3. To determine if HM was unique in the way his brain damage affected his memory

Q

METHOD:

Sample

A

6 Ps with amnesia and various brain damage

> 2 patients with damage to only the hippocampus in the temporal lobe (least damage)

> 3 patients with damage to the medial temporal lobe and anterolateral temporal lobe (most damage)

> HM - damage to his medial and lateral temporal lobe

Control group
> 8 Ps
> Matched to brain damaged patients by age, sex & education (factors that could affect ability)
