本研究通过系统地考察任务无关特征对视觉工作记忆选择性编码的干扰，探讨了视觉工作记忆选择性编码的机制。刺激是由三个特征（颜色，形状和位置）定义的物体，在延迟期间，任何特征都可以在两个物体之间切换。此外，单探针和全探针试验在实验区内随机化，以研究记忆提取的影响。一系列的相关特征开关检测任务，其中一个功能是任务无关的，表明来自任务无关的功能的干扰，只观察到在颜色-形状任务，这表明颜色和形状信息可以成功地过滤掉，但位置信息不能，即使位置是一个任务无关的功能。因此，尽管位置信息以相对自动的方式独立于任务需求被添加到对象表示，但是其他特征（例如，颜色、形状）可以灵活地添加到对象表示。
The current study examined selective encoding in visual working memory by systematically investigating interference from task-irrelevant features. The stimuli were objects defined by three features (color, shape, and location), and during a delay period, any of the features could switch between two objects. Additionally, single- and whole-probe trials were randomized within experimental blocks to investigate effects of memory retrieval. A series of relevant-feature switch detection tasks, where one feature was task-irrelevant, showed that interference from the task-irrelevant feature was only observed in the color-shape task, suggesting that color and shape information could be successfully filtered out, but location information could not, even when location was a task-irrelevant feature. Therefore, although location information is added to object representations independent of task demands in a relatively automatic manner, other features (e.g., color, shape) can be flexibly added to object representations.
