Abstract

Serial dependence (SD) is said to occur when the judgment of a current stimulus is drawn toward a no longer relevant stimulus from the recent past. Working memory (WM) contributes to the ability to discriminate between irrelevant and relevant sensory impressions. How WM contributes to SD in facial identity remains to be fully understood. In the present study, we used a WM task with varying load interleaved with a facial matching task to investigate the relations between SD in facial identity and WM. EEG was recorded to capture perceptual face processing and WM maintenance. Overall, statistically significant SD effects were obtained only at high WM load. In addition, individual differences in WM capacity predicted SD. Participants with low WM capacity showed significant SD effects regardless of changes in WM load, while participants with high WM capacity showed significant SD only at high WM load. EEG results showed significant differences in perceptual and WM processing for participants with high WM capacity, while no significant differences were obtained for participants with low WM capacity. Neural correlates of WM maintenance, and perceptual processing of a previous face were directly related to SD. The results suggest that WM capacity contributes to SD in facial identity, in terms of selective suppression of task-irrelevant and selective maintenance of task-relevant information.

工作记忆容量调节面部识别的序列依赖性：来自行为和脑电图数据的证据。

当对当前刺激的判断被最近的过去不再相关的刺激所吸引时，序列依赖（SD）就会发生。工作记忆（WM）有助于区分无关和相关的感觉印象的能力。WM对SD在面部识别中的作用机制还有待进一步研究。在本研究中，我们使用不同负荷的人脸识别任务与人脸匹配任务交叉，研究人脸识别的SD与人脸识别的关系。记录脑电图捕捉感知人脸处理和WM维持。总的来说，只有在高WM负荷下，SD效应才有统计学意义。此外，WM容量的个体差异预测了SD。低WM能力的被试无论在WM负荷下都表现出显著的SD效应，而高WM能力的被试仅在高WM负荷下表现出显著的SD效应。脑电结果显示，高脑机处理能力的被试在知觉和脑机加工上存在显著差异，而低脑机处理能力的被试在知觉和脑机加工上无显著差异。WM维持和前一张面孔知觉加工的神经相关与SD直接相关。结果表明，WM能力通过选择性地抑制任务无关信息和选择性地维持任务相关信息来促进面部识别的SD。

期刊介绍： Vision Research is a journal devoted to the functional aspects of human, vertebrate and invertebrate vision and publishes experimental and observational studies, reviews, and theoretical and computational analyses. Vision Research also publishes clinical studies relevant to normal visual function and basic research relevant to visual dysfunction or its clinical investigation. Functional aspects of vision is interpreted broadly, ranging from molecular and cellular function to perception and behavior. Detailed descriptions are encouraged but enough introductory background should be included for non-specialists. Theoretical and computational papers should give a sense of order to the facts or point to new verifiable observations. Papers dealing with questions in the history of vision science should stress the development of ideas in the field.
