有很好的证据表明，生物感知系统利用了世界的时间连续性：当被要求再现或评价顺序呈现的刺激（几乎在任何维度上都不同）时，受试者通常会偏向前一个刺激，表现出所谓的“序列依赖”。在这个阶段，还不清楚串行依赖性是由感知系统内的平均值引起的，还是在以后的阶段。在这里，我们证明了强烈的串行依赖性发生在感知和决策过程中，很少有贡献的反应。使用一种技术来隔离纯感知效应（Fritsche，Mostert，de Lange，2017），我们在方向判断中表现出强烈的序列依赖性，在理论考虑预测效果最大的方向范围内。在第二个实验中，我们将反应与刺激分离，以表明序列依赖只发生在刺激之间，而不是反应之间。结果表明，串行依赖性是重要的感知，利用时间冗余，以提高感知效率。
There is good evidence that biological perceptual systems exploit the temporal continuity in the world: When asked to reproduce or rate sequentially presented stimuli (varying in almost any dimension), subjects typically err toward the previous stimulus, exhibiting socalled ''serial dependence.'' At this stage it is unclear whether the serial dependence results from averaging within the perceptual system, or at later stages. Here we demonstrate that strong serial dependencies occur within both perceptual and decision processes, with very little contribution from the response. Using a technique to isolate pure perceptual effects (Fritsche, Mostert, & de Lange, 2017), we show strong serial dependence in orientation judgements, over the range of orientations where theoretical considerations predict the effects to be maximal. In a second experiment we dissociate responses from stimuli to show that serial dependence occurs only between stimuli, not responses. The results show that serial dependence is important for perception, exploiting temporal redundancies to enhance perceptual efficiency.
