摘要：即使在执行一项简单、重复的任务时，人类的行为也会随时随地发生变化。错误之后通常会做出谨慎的反应，从而最大限度地减少后续的干扰。然而，关于最终正确的反应的执行变化如何影响随后的行为，我们知之甚少。我们要求参与者将手伸向呈现在分心物中的独特颜色的目标，并根据对运动轨迹的分析，创建了两个类别来描述参与者在正确试验中的反应；部分错误指的是观察者在重新定向运动并准确指向目标之前最初选择一个非目标进行行动的试验，而直接运动指的是直接选择目标进行行动的试验。我们发现，在部分错误后的试验中，启动手部运动的潜伏期比直接运动后的试验更短。此外，当目标和分心物体的颜色重复时，与直接运动相比，部分错误后的运动时间和朝向分心物体的到达运动曲率更大。最后，当颜色重复时，在部分错误试验后，部分错误比直接动作更频繁，在直接动作试验后，直接动作更频繁。后一种效应对重复任务情境的依赖表明，在一个整合的注意-行动系统中，较高水平的认知机制参与其中，在这个系统中，部分错误或直接运动反应的执行会影响记忆表征，从而在随后的实验中偏向于表现。总之，这些结果表明，是否选择一个非目标进行行动对随后的行为有可测量的影响。
Abstract:Abstract Humans exhibit variation in behavior from moment to moment even when performing a simple, repetitive task. Errors are typically followed by cautious responses, minimizing subsequent distractor interference. However, less is known about how variation in the execution of an ultimately correct response affects subsequent behavior. We asked participants to reach toward a uniquely colored target presented among distractors and created two categories to describe participants' responses in correct trials based on analyses of movement trajectories; partial errors referred to trials in which observers initially selected a nontarget for action before redirecting the movement and accurately pointing to the target, and direct movements referred to trials in which the target was directly selected for action. We found that latency to initiate a hand movement was shorter in trials following partial errors compared to trials following direct movements. Furthermore, when the target and distractor colors were repeated, movement time and reach movement curvature toward distractors were greater following partial errors compared to direct movements. Finally, when the colors were repeated, partial errors were more frequent than direct movements following partial-error trials, and direct movements were more frequent following direct-movement trials. The dependence of these latter effects on repeated-task context indicates the involvement of higher-level cognitive mechanisms in an integrated attention-action system in which execution of a partial-error or direct-movement response affects memory representations that bias performance in subsequent trials. Altogether, these results demonstrate that whether a nontarget is selected for action or not has a measurable impact on subsequent behavior.
