Event-related potential study of attention capture by affective sounds.

摘要: Affective pictures trigger attentional responses in humans but very little is known about the processing of affective environmental sounds. Here, we used an oddball event-related potential paradigm to determine saliency unpleasant sounds presented among affectively neutral Participants performed a one-back task while listening pseudo-randomized sound sequences comprising 70% sounds, 15% matched peak intensity, and louder Louder elicited larger N1 component significant P3a variation with central distribution. Unpleasant did not affect early components frontocentral modulation. We conclude that spontaneously capture human attention fail modulate perceptual when intensity controlled.
