When processing sequences of rapidly varying stimuli, the visual system must satisfy two conflicting requirements. To maintain perceptual continuity, sequential stimuli must be integrated into a single, unified percept. On the other hand, to detect rapid changes, sequential stimuli must be segregated from each other. We propose that these conflicting demands are reconciled by a process that codes the temporal relationship between contiguous stimuli: Stimuli that are coded as co-extensive are integrated and those that are coded as disjoint are segregated. This approach represents a conceptual departure from the more traditional "intrinsic persistence" view of temporal integration. The approach provides a parsimonious account of the results of two temporal-integration tasks in which the durations of the leading and trailing displays were varied over a broad range. The data were accurately fit by a quantitative model in which temporal codes were determined by the correlation in time between the visual responses to the leading and trailing displays.

超越可见持久性:视觉处理中时间整合和分离的另一种解释
当处理快速变化的刺激序列时,视觉系统必须满足两个相互矛盾的要求。为了保持知觉的连续性,必须将连续的刺激整合成一个单一的、统一的知觉。另一方面,为了检测快速变化,必须将连续刺激彼此隔离。我们建议通过对连续刺激之间的时间关系进行编码的过程来调和这些相互冲突的需求:被编码为共同扩展的刺激被整合,被编码为不相交的刺激被隔离。这种方法代表了与更传统的“内在持久性”时间整合观点的概念背离。该方法提供了两个时间整合任务的结果的简洁说明,其中前导和尾随显示的持续时间在很宽的范围内变化。数据由定量模型精确拟合,其中时间代码由对前导和尾随显示的视觉响应之间的时间相关性确定。
