大多数注意理论认为，我们在视觉工作记忆中保持注意模板，以控制信息的选择。在本研究中，我们直接测试这一建议，通过测量人类事件相关电位（ERP）在视觉搜索任务中，目标是线索在每次审判的对侧延迟活动（CDA）。在这里，我们表明，CDA可以用来衡量的注意模板在视觉工作记忆的维护，而处理复杂的视觉场景。此外，这种方法使我们能够直接观察到从工作记忆到长期记忆表征的转变，这些记忆表征控制着学习过程中的注意力，并且随着寻找同一目标对象的经验积累而增加。我们的研究结果提供了明确的支持，在注意力，学习和自动性理论的几个关键建议。
Most theories of attention propose that we maintain attentional templates in visual working memory to control what information is selected. In the present study, we directly tested this proposal by measuring the contralateral-delay activity (CDA) of human event-related potentials (ERPs) during visual search tasks in which the target is cued on each trial. Here we show that the CDA can be used to measure the maintenance of attentional templates in visual working memory while processing complex visual scenes. In addition, this method allowed us to directly observe the shift from working memory to long-term memory representations controlling attention as learning occurred and experience accrued searching for the same target object. Our findings provide definitive support for several critical proposals made in theories of attention, learning, and automaticity.
