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
