摘要/Abstract

摘要： Lavie的注意负载理论认为:靶任务的加工负载决定无关干扰子被加工的程度；当靶任务的注意负载增高时，外周干扰子被注意的程度会减弱。实验通过改变靶任务的负载、以及干扰子出现的时程，发现干扰子在低和高负载条件下同样可以产生刺激驱动的注意捕获：低负载在333ms左右；高负载在0~167ms左右。这说明在高负载条件下干扰子同样会吸引注意，只是在时程上与低负载不同。

Abstract: Lavie’s theory of attention load proposed that the processing load in a relevant target task determines the extent to which irrelevant distractors are processed. When perceptual load is high, the extent to which irrelevant distractors are processed decreases. We tested this theory by changing the perceptual load in target tasks and interstimulus intervals between target and distractor. We found that stimulus-driven attentional capture effect existed in both low- and high-load conditions: 333ms in low-load condition, 0~167ms in high-load condition. These results suggested that attentional capture can be observed in high-load condition at different time courses compared with that in the low-load condition.

Key words: stimulus-driven attentional capture, attention load, distractor
