The aim of Experiment 1 was to investigate the effect of response inhibition to attended pictures on the emotional evaluation of these pictures. To this end, participants were required to complete a go/no-go task, followed by a preference-rating task. In the go/no-go task, participants were asked to press space key when the picture of a specified target category was presented (i.e., a go trial) and to suppress the key response when the picture did not belong to the target category (i.e., a no-go trial). Previous studies have demonstrated that the pictures presented as no-go stimuli were rated less positively in subsequent rating than images presented as go stimuli (Kiss et al., 2008; Doallo et al., 2012). Thus, if attention plays an important role in emotional devaluation through response inhibition, we should obtain the same results as reported in the previous studies (Kiss et al., 2008; Doallo et al., 2012).
