解释和预测他人行为的能力在人类中高度进化，并被认为在他们的认知行为中发挥着核心作用。然而，没有直接证据表明这种能力对感觉处理有明显的好处。我们的定量行为实验表明，人类代理的视觉歧视的影响，第二代理的存在。这种效应取决于两个代理是否以有意义的同步方式进行交互（通过战斗或跳舞），允许一个代理的动作作为另一个代理的预期动作的预测因子，即使同步与视觉辨别任务无关。我们的研究结果表明，动作理解对人类从其他人的动作中提取视觉信息的能力产生了广泛的影响，为其在性能方面的重要性提供了定量证据。
The ability to interpret and predict other people's actions is highly evolved in humans and is believed to play a central role in their cognitive behavior. However, there is no direct evidence that this ability confers a tangible benefit to sensory processing. Our quantitative behavioral experiments show that visual discrimination of a human agent is influenced by the presence of a second agent. This effect depended on whether the two agents interacted ( by fighting or dancing) in a meaningful synchronized fashion that allowed the actions of one agent to serve as predictors for the expected actions of the other agent, even though synchronization was irrelevant to the visual discrimination task. Our results demonstrate that action understanding has a pervasive impact on the human ability to extract visual information from the actions of other humans, providing quantitative evidence of its significance in performance.
