注视方向是人类和其他灵长类动物重要的社会信号。在这项研究中，我们使用的适应范式，探讨在人类注视知觉的功能组织。适应一致的凝视或凝视产生了一种强大的错觉，几乎消除了观察者对适应方向的凝视的感知;凝视那一边被视为指向正前方，尽管对另一边的凝视感知没有受到影响。即使当适应和测试刺激之间的视网膜定位映射被大小或头部方向的变化破坏时，这种显著的分离仍然存在，这表明我们的研究结果并不反映对低水平视觉特性的适应。此外，适应转移视线并不影响判断线平分，说明我们的研究结果并不反映一般的空间偏见。我们的研究结果提供了证据，证明人类有不同的神经元群体，这些神经元对特定的注视方向有选择性地做出反应。
Gaze direction is an important social signal in humans and other primates. In this study, we used an adaptation paradigm to investigate the functional organization of gaze perception in humans. Adaptation to consistent leftward or rightward gaze produced a powerful illusion that virtually eliminated observers' perception of gaze in the adapted direction; gaze to that side was seen as pointing straight ahead, though perception of gaze to the opposite side was unimpaired. This striking dissociation held even when retinotopic mapping between adaptation and test stimuli was disrupted by changes in size or head orientation, suggesting that our findings do not reflect adaptation to low-level visual properties. Moreover, adaptation to averted gaze did not affect judgments of line bisection, illustrating that our findings do not reflect a general spatial bias. Our findings provide evidence that humans have distinct populations of neurons that are selectively responsive to particular directions of seen gaze.
