Figure 4.

Reaction times during acquisition of visual discrimination (VD). Session-level analysis during the first 5–7 sessions of pairwise VD learning. Latencies to make (A) correct or (B) incorrect responses and (C) to collect rewards following a correct response are illustrated. Data are presented as the mean ± standard error of the mean per session. Significant main effect of genotype is indicated as: ^#p < 0.05. All original p values associated with the effects of genotype, session and genotype × compound session interaction were adjusted for multiple comparisons using the Holm–Šídák correction. ^+/− heterozygous, ^−/Y hemizygous, ^−/− homozygous, ^+/+ WT
