Many recent findings suggest that stimuli that are perceived to be the consequence of one's own actions are processed with priority. According to the preactivation account of intentional binding, predicted consequences are preactivated and hence receive a temporal advantage in processing. The implications of the preactivation account are important for theories of attention capture, as temporal advantage often translates to attention capture. Hence, action might modulate attention capture by feature singletons. Experiment 1 showed that a motion onset and color change captured attention only when it was preceded by an action. Experiment 2 showed that the capture occurs only with predictable, but not with unpredictable, consequences of action. Experiment 3 showed that even when half the display changed color at display transition, they were all prioritized. The results suggest that action modulates attentional control.
许多最新的发现表明,被感知为自身行为结果的刺激会被优先处理。根据意图绑定的预激活理论,预测的结果会被预先激活,因此在处理过程中会获得时间优势。预激活理论的意义对于注意捕获理论很重要,因为时间优势通常会转化为注意捕获。因此,动作可能会通过特征单一性来调节注意捕获。实验 1 表明,只有在动作之前出现运动起始和颜色变化时,注意力才会被捕获。实验 2 表明,只有可预测的、而不是不可预测的动作结果才会发生捕获。实验 3 表明,即使在显示转换时一半的显示颜色发生变化,它们也都被优先处理。结果表明,动作调节了注意力控制。
