  • Different attentional selection modes of object information in the encoding and maintenance stages of visual working memory

    Chao Pang, Yanzhang CHEN et al.ARTICLEActa Psychologica Sinica2023

    摘要: 视觉工作记忆不同加工阶段(编码、维持)对多特征客体信息的注意选择模式是否相同目前仍存在争议。本研究采用变化觉察范式, 引入前注意线索和后注意线索, 分别探测在视觉工作记忆编码和维持两个阶段中的注意选择模式。3个实验结果显示, 在前注意线索试次中, 被试对任务相关特征变化的觉察显著受到任务无关特征变化的干扰, 表现为任务无关特征变化条件相比于不变条件的反应更慢, 报告标准更低; 且该干扰效应并不受记忆负荷的影响。而在后注意线索试次中, 仅在低记忆负荷条件下(实验1a/1b)存在干扰效应, 当记忆负荷增大后(实验2/3)干扰效应消失。结果表明, 在视觉工作记忆编码阶段, 客体中任务相关与无关特征均被编码进视觉工作记忆并相互竞争注意资源; 而在维持阶段, 任务无关特征仅在低记忆负荷条件下得到加工。结果揭示, 在编码阶段的注意选择模式是基于客体的; 而维持阶段的注意选择模式是基于特征的, 且受到记忆负荷的调控

  • The effects of expectation on attention are dependent on whether expectation is on the target or on the distractor

    Open AccessZinuan Zhou, Yanzhang CHEN et al.ARTICLEActa Psychologica Sinica2022

    Both attention and expectation are important mechanisms to help the brain filter and process information in a complex environment. However, there is still no unified conclusion about whether they act interactively or additively on perception. Previous studies that used the spatial cueing paradigm to address this issue might have confounded attention and expectation. Recently, researchers have made efforts to define attention and expectation ortho…

  • The modulation of working memory load and perceptual load on attentional guidance from representations of working memory

    Bao Zhang, Zhang Bao et al.ARTICLEActa Psychologica Sinica2017

    摘要: 本研究采用4个眼动实验探讨不同知觉负载条件下的视觉搜索任务中工作记忆负载对基于工作记忆表征的注意引导效应的影响。实验1和实验3采用低知觉负载的视觉搜索任务, 结果在视觉工作记忆负载为1和2时观察到了显著的注意引导效应, 但当负载增加到4时注意引导效应消失了; 实验2和实验4采用高知觉负载的视觉搜索任务, 结果发现注意引导效应在工作记忆负载增加到2时就已经消失了。上述结果表明:工作记忆负载和知觉负载都能够通过调控认知资源的方式来影响工作记忆表征对注意的引导, 当认知资源充足时, 工作记忆能够同时保持多个记忆表征对视觉注意的引导
