在RSVP范式中干扰物在知觉、辨别和反应阶段干扰目标加工

Distractors Interfere with Target Processing at Perceptual, Conceptual and Response Stage in RSVP Paradigm

干扰物在RSVP范式中的作用机制尚未十分明确。本研究利用单目标RSVP范式操纵紧跟目标的干扰物的有无及与目标类别和反应的一致性进行探究。结果表明,紧跟目标的干扰物在知觉、辨别及反应阶段均影响目标识别。当前结果说明,目标引起的注意增强是缓慢的过程,这一特性导致目标引起的注意增强也增强了紧随其后的干扰物,诱发注意控制进行调节。

The mechanism of distractors in the RSVP paradigm remains unclear. In this study, the sin-gle-target RSVP paradigm was used to manipulate the presence or absence of the distractor (D) that immediately follow the target and the congruency between the target and the distractor in category and response. The results show that distractors immediately following the target affect target recognition at the perception, category, and response stages. The current results suggest that target-evoked attention enhancement is a slow process, a property that causes target-evoked attention enhancement to also enhance closely following distractors, inducing attentional control for modulation.
