In the current study, we examined how short-term memory for location-identity feature bindings is influenced by subsequent cognitive and perceptual processing demands. Previous work has shown that memory performance for feature bindings can be disrupted by the presentation of subsequent visual information, particularly when this information is similar to that held in memory. The present study demonstrates that memory performance for feature bindings can be profoundly disrupted by also requiring a response to visual information presented subsequent to the visual memory array. Across five experiments, memory for a location-identity binding was substantially impaired following a localization response to a following item that matched the location but mismatched the identity of the memory target. The results point to an important role for action in the episodic integration processes that control short-term visual memory performance.
在当前研究中，我们考察了位置-身份特征绑定的短期记忆如何受到后续认知和感知加工需求的影响。先前的研究表明，特征绑定的记忆表现会受到后续视觉信息呈现的干扰，尤其是当这些信息与记忆中的信息相似时。本研究表明，对视觉记忆阵列之后呈现的视觉信息作出反应的要求，也会严重干扰特征绑定的记忆表现。在五个实验中，对与记忆目标位置匹配但身份不匹配的后续项目进行定位反应后，位置-身份绑定的记忆受到了显著损害。结果表明，行动在控制短期视觉记忆表现的情景整合过程中起着重要作用。
