Fig 1. Task and experimental stimuli.

(A) The 6 screen pictures represent the different stages of the task. (B) Stimuli: examples of the four possible conditions. In this example, the participants were asked to feed the orange animals (i.e, orange animals were Go trials and blue animals were Nogo trials). (1) Go Congruent (GC); (2) Go Incongruent (GI); (3) Nogo Congruent (NGC) and (4) Nogo Incongruent (NGI). The cue was presented in the top or in the bottom half of the screen. Four different animals for each color were used.
