注意力和工作记忆的限制对视觉表征设置了严格的限制，然而研究人员很少认识到这些限制是如何在持续的视觉引导行为中限制信息获取的。实验对象在虚拟环境中完成一项砖块分类任务。在大约10%的试验中，改变了砖块的一个特征。特征变化的变化检测率通常很低，并且依赖于特征与分类任务的提取和放下相关性。受试者的分类决策表明，由于未能更新已更改的功能，可能会错过更改。作者还探讨了手和眼的行为是如何在整个任务中协调视觉信息的战略性获取和存储的。
Attention and working memory limitations set strict limits on visual representations, yet researchers have little appreciation of how these limits constrain the acquisition of information in ongoing visually guided behavior. Subjects performed a brick sorting task in a virtual environment. A change was made to 1 of the features of the brick being held on about 10% of trials. Rates of change detection for feature changes were generally low and depended on the pick-up and put-down relevance of the feature to the sorting task. Subjects' sorting decision suggests that changes may be missed because of a failure to update the changed feature. The authors also explore how hand and eye behavior are coordinated for strategic acquisition and storage of visual information throughout the task.
