摘　　要：采用变化觉察范式,在工作记忆保持阶段插入客体特征辨别或视觉搜索次任务,探讨基于客体的注意和基于空间的注意对视觉工作记忆外部特征绑定表征的影响。结果发现,与单特征相比,两类次任务均对外部特征绑定的记忆成绩损耗更大。这表明视觉工作记忆中外部特征绑定的表征比单特征消耗更多基于客体的注意和更多基于空间的注意。Two experiments were designed to explore the role of object-based attention and space-based attention in retaining binding of extrinsic features in visual working memory.Participants performed a change-detection task with single probe while a secondary object-based feature report task or a space-based visual search task was inserted during the retention interval to consume object-based attention or space-based attention.Both experiments showed that bindings were more impared by a secondary task than features.These experimental results suggest that maintaining extrinsic feature binding in visual working memory requires more object-based attention and more space-based attention than maintaining features.

关 键 词：视觉工作记忆 外部特征绑定 基于客体的注意 基于空间的注意
