视觉感知系统地偏向于最近的输入：感知的方向，数字和面孔身份被拉向以前看到的刺激。为了更好地了解发生序列依赖的大脑水平，本研究考察了其空间调谐。在三个实验中，序列依赖性发生在占据相同视网膜位置的刺激之间。在遥远的视网膜位置的刺激之间的串行依赖性较小，即使当刺激在外部空间中占据相同的位置。因此，序列依赖发生的空间窗口是视网膜定位的，但很宽，这表明序列依赖发生在视觉处理的后期。
Visual perception is systematically biased towards input from the recent past: perceived orientation, numerosity, and face identity are pulled towards previously seen stimuli. To better understand the brain level at which serial dependence occurs, the present study examined its spatial tuning. In three experiments, serial dependence occurred between stimuli occupying the same retinal position. Serial dependence between stimuli at distant retinal locations was smaller, even when the stimuli occupied the same location in external space. The spatial window over which serial dependence occurs is thus retinotopic, but wide, suggesting that serial dependence occurs at late stages of visual processing.
