在反扫视任务中，参与者被要求在与周边视觉线索（PVC）相反的方向上扫视。这一范式常被用来研究反射反应的抑制以及自主反应的产生。然而，尚不清楚这一任务的不同版本在多大程度上探测相同的基本进程。在这里，我们探索了随机早期反应。抑制和迟动（SERIA）模型之间的延迟任务线索和PVC影响反应时（RT）和错误率（ER）时，正反突击试验随机交错。具体来说。我们将任务线索先于PVC出现的情况与PVC同时作为任务线索的情况进行了对比。摘要统计表明，ER和RT减少和上下文的影响很大程度上消除了任务之前，PVC出现的信号。SERIA模型在这两种情况下都考虑了RT和ER，并且比其他候选模型更好。建模表明，自愿亲和反突击频繁在这两种情况下。此外，早期任务提示呈现的结果在更好地控制反射眼跳，导致更少的快速反眼跳错误和更快速正确的正视。最后，highlatency错误被证明是普遍存在的两种情况。总之。SERIA提供了一个解释延迟和nondelayed antisaccade task.NEW & NOTEWORTHY在这篇文章中，我们使用一个计算模型来研究混合antisaccade任务的差异。我们对比两种情况下，任务线索提出之前或同时与扫视目标。建模提供了一个高度准确的帐户参与者的行为，并表明，大量的prosaccades是自愿的行动。此外，我们提供了一个详细的定量分析的类型的错误发生在赞成和反对accade试验。
In the antisaccade task participants are required to saccade in the opposite direction of a peripheral visual cue (PVC). This paradigm is often used to investigate inhibition of reflexive responses as well as voluntary response generation. however, it is not clear to what extent different versions of this task probe the same underlying processes. Here, we explored with the Stochastic Early Reaction. Inhibition, and late Action (SERIA) model how the delay between task cue and PVC affects reaction time (RT) and error rate (ER) when pro- and antisaccade trials are randomly interleaved. Specifically. we contrasted a condition in which the task cue was presented before the PVC with a condition in which the PVC served also as task cue. Summary statistics indicate that ERs and RTs are reduced and contextual effects largely removed when the task is signaled before the PVC appears. The SERIA model accounts for RT and ER in both conditions and better so than other candidate models. Modeling demonstrates that voluntary pro- and antisaccades are frequent in both conditions. Moreover, early task cue presentation results in better control of reflexive saccades, leading to fewer fast antisaccade errors and more rapid correct prosaccades. Finally, highlatency errors are shown to be prevalent in both conditions. In summary. SERIA provides an explanation for the differences in the delayed and nondelayed antisaccade task.NEW & NOTEWORTHY In this article, we use a computational model to study the mixed antisaccade task. We contrast two conditions in which the task cue is presented either before or concurrently with the saccadic target. Modeling provides a highly accurate account of participants' behavior and demonstrates that a significant number of prosaccades are voluntary actions. Moreover, we provide a detailed quantitative analysis of the types of error that occur in pro- and antisaccade trials.
