EU: emotion rating on unpleasant pictures, EP: emotion rating on pleasant pictures, FU: frequency rating on unpleasant pictures, FP: frequency rating on pleasant pictures. Responses < 500 ms were excluded from RT analysis as they most likely reflected carried-over late responses to previous trials. Two-way repeated measures ANOVA of reaction time using the factors task and valence revealed a significant main effect of task (F (1, 14) = 36.5, p < 0.001).
