摘要

我们的大脑有时会以偏差的方式呈现视觉信息。当我们感知或在视觉工作记忆(WM)中保持同时或顺序呈现的多个视觉特征时,它们可能会相互影响,从而产生报告偏差。目标定向注意如何影响目标表征,尤其是对分心物的注意是否会调节对目标的报告偏差,目前尚不完全清楚。我们的研究调查了在感知过程中,当目标与(1)一个被注意的分心物,(2)一个未被注意的分心物,以及(3)两种分心物同时出现时,目标的WM偏差。研究发现,目标 WM 被报告为排斥同时出现的分心物,无论是有分心物还是无分心物,这表明在感知过程中出现排斥偏差并不需要注意。此外,对分心物的目标定向注意会调节项目间相互作用的强度,发现当注意指向分心物时,排斥偏差比不指向分心物时更强。然而,与注意到的分心物相关的夸大排斥可能是由于与记忆任务的相关性增加以及(或)WM 负荷而非空间注意造成的。相反,对分心物的空间注意会增加将分心物误报为目标物的几率。

Repulsion bias is insensitive to spatial attention, yet expands during active working memory maintenance

Our brain sometimes represents visual information in a biased manner. Multiple visual features presented simultaneously or sequentially may interact with each other when we perceive them or maintain them in visual working memory (WM), giving rise to report bias. How goal-directed attention influences target representation is not fully understood, especially concerning whether attention towards distractors modulates report bias for the target. Our study investigated the WM biases of the target when it is concurrent with (1) one attended distractor only, (2) one unattended distractor only, and (3) both kinds of distractors during perception. It was found that the target WM is reported as being repelled away from concurrent distractors, attended or unattended, suggesting attention is not necessary for the occurrence of repulsion bias during perception. Furthermore, goal-directed attention towards the distractors modulates the strength of interitem interaction, and the repulsion bias was found to be stronger when attention was directed toward the distractor than when it was not. However, the exaggerated repulsion associated with the attended distractor is likely due to increased relevance to the memory task and (or) WM load instead of spatial attention. In contrast, spatial attention towards the distractor increases the chances of misreporting the distractor for the target.

期刊介绍: The journal Attention, Perception, & Psychophysics is an official journal of the Psychonomic Society. It spans all areas of research in sensory processes, perception, attention, and psychophysics. Most articles published are reports of experimental work; the journal also presents theoretical, integrative, and evaluative reviews. Commentary on issues of importance to researchers appears in a special section of the journal. Founded in 1966 as Perception & Psychophysics, the journal assumed its present name in 2009.
