本研究探讨了视觉短时记忆中注意在维持特征绑定中的作用。在变化检测范式中，参与者试图检测多个对象的颜色和方向的变化;这些变化包括特征记忆条件下的新特征值和结合记忆条件下弓现有特征值的变化。在关键实验中，一个苛刻的视觉搜索任务，需要连续转移的空间注意力插入期间的延迟间隔的变化检测任务。如果注意力对于维持特征绑定比维持未绑定特征值更重要，那么需要注意力的搜索任务应该特别破坏绑定记忆任务的性能。与此建议相反，有人发现，记忆绑定和记忆功能同样受损的搜索任务。
This study examined the role of attention in maintaining feature bindings in visual short-term memory. In a change-detection paradigm, participants attempted to detect changes in the colors and orientations of multiple objects; the changes consisted of new feature values in a feature-memory condition and changes in bow existing feature values were combined in a binding-memory condition. In the critical experiment, a demanding visual search task requiring sequential shifts of spatial attention was interposed during the delay interval of the change-detection task. If attention is more important for the maintenance of feature bindings than for the maintenance of unbound feature values, the attention-requiring search task should specifically disrupt performance in the binding-memory task. Contrary to this proposal, it was found that memory for bindings and memory for features were equally impaired by the search task.
