Statistical learning of target selection and distractor suppression shape attentional priority according to different timeframes

Abstract Recent findings suggest that attentional and oculomotor control is heavily affected by past experience, giving rise to selection and suppression history effects, so that target selection is facilitated if they appear at frequently attended locations, and distractor filtering is facilitated...
