Table 1 Behavioural performance (means and standard deviations) in the one-back visual working memory and odd-one-out tasks: data are split by condition and by APOE group.
APOE-ε4 carriers | Non-carriers | |
|---|---|---|
Task A : Visual working memory task | n = 15 | n = 15 |

Faces | 0.55 (0.19) | 0.52 (0.22) |
Objects | 0.78 (0.12) | 0.70 (0.23) |
Scrambled objects | 0.57 (0.23) | 0.56 (0.19) |
Task B : Odd-one-out task | n = 13 | n = 12 |
