无关干扰在高感知负荷下的作用

Perceptual load theory is a key framework in visual attention research, demonstrating that under high-load conditions, fully irrelevant distractors are no longer processed and do not disrupt task performance. In our recent work (Manini et al., 2026), we replicated this effect. However, we also found that under high load, the distractor not only failed to impair performance but actually led to faster reaction times (RTs) in distractor-present trials. In the attentional capture literature, this reversed effect is typically considered to reflect distractor suppression. However, in the perceptual
