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.
感知的方向、数量和面部身份都会被拉向之前见过的刺激。为了更好地理解串行依赖发生的大脑水平,本研究检查了它的空间调谐。在三个实验中,刺激在同一视网膜位置时会出现串行依赖。即使刺激在外部空间占据相同位置,远距离视网膜位置的刺激之间的串行依赖也较小。因此,串行依赖发生的空间窗口是视网膜特有的,但很宽,这表明串行依赖发生在视觉处理的后期阶段。
