即使1和相同事件的视觉和听觉信息通常不会同时到达感觉受体，由于模态的不同物理传输时间，大脑至少在一定范围内的感觉到达时间差内保持对事件的单一感知。这个“时间窗口的整合”（TWIN），其重新校准由于任务要求，注意力和其他变量的属性，最近被深入研究。然而，到目前为止，还没有一个统一的定义的“时间窗口”跨不同的范式来衡量其宽度。在这里，我们提出了这样一个定义的基础上，我们的TWIN模型（Colonius & Diederich，2004）。它适用于时间顺序（或时间性）的判断以及反应时间（RT）范式。通过将TWIN模型与两种范式的数据拟合，重新分析Megevand，Molholm，Nayak和Foxe（2013）的数据，我们证实了作者的假设，即RT任务中的时间窗口往往比时间顺序判断（TOJ）任务更宽。这是迈向双胞胎统一概念的第一步，应该是一个有价值的工具，可以指导对这个迄今为止有点难以捉摸的概念的神经和认知基础的研究。
Even though visual and auditory information of 1 and the same event often do not arrive at the sensory receptors at the same time, due to different physical transmission times of the modalities, the brain maintains a unitary perception of the event, at least within a certain range of sensory arrival time differences. The properties of this "temporal window of integration" (TWIN), its recalibration due to task requirements, attention, and other variables, have recently been investigated intensively. Up to now, however, there has been no consistent definition of "temporal window" across different paradigms for measuring its width. Here we propose such a definition based on our TWIN model (Colonius & Diederich, 2004). It applies to judgments of temporal order (or simultaneity) as well as to reaction time (RT) paradigms. Reanalyzing data from Megevand, Molholm, Nayak, & Foxe (2013) by fitting the TWIN model to data from both paradigms, we confirmed the authors' hypothesis that the temporal window in an RT task tends to be wider than in a temporal-order judgment (TOJ) task. This first step toward a unified concept of TWIN should be a valuable tool in guiding investigations of the neural and cognitive bases of this so-far-somewhat elusive concept.
