This study investigated the recognition of affective images flashes of different stimuli modalities (faces and scenes) and emotional valences (pleasant, unpleasant and neutral). Results showed that the difference among stimuli's perceptual salience can overlap the effects of emotional valence. As the recognition between pleasant scenes and faces, unpleasant ones did not differ. On the other hand the emotional valences showed differences: pleasant images were recognized faster compared to unpleasant images and pleasant faces were more recognized than neutral faces. Taking into account literature these results suggest that unpleasant images rapidly presented weaken activation in the amygdala and intensify it in the prefrontal cortex, which takes longer to process information.
