个人可以快速轻松地识别面部表情，这对社会感知和情绪调节至关重要。这种对即使是轻微的面部变化的敏感性也可能导致随着时间的推移对个人表情的不稳定感知。因此，视觉系统必须在准确性和保持感知稳定性之间取得平衡。然而，以前的研究集中在我们对变化的表达的敏感性上，表达稳定性背后的机制仍然是一个悬而未决的问题。最近的研究结果表明，对面部身份的感知系统地偏向于最近看到的视觉输入。这种积极的知觉拉力，或序列依赖，可能有助于稳定知觉表达。为了验证这一点，观察者判断随机的面部表情变化，从高兴到悲伤到愤怒。我们发现，只有当1-back和当前面孔具有相似的身份时，感知到的表情才会被拉向先前看到的表情。我们的研究结果与表达连续性场的存在是一致的，表达连续性场是一种促进情绪感知稳定性的专门机制，有助于促进社会互动和情绪调节。
Individuals can quickly and effortlessly recognize facial expressions, which is critical for social perception and emotion regulation. This sensitivity to even slight facial changes could result in unstable percepts of an individual's expression over time. The visual system must therefore balance accuracy with maintaining perceptual stability. However, previous research has focused on our sensitivity to changing expressions, and the mechanism behind expression stability remains an open question. Recent results demonstrate that perception of facial identity is systematically biased toward recently seen visual input. This positive perceptual pull, or serial dependence, may help stabilize perceived expression. To test this, observers judged random facial expression morphs ranging from happy to sad to angry. We found a pull in perceived expression toward previously seen expressions, but only when the 1-back and current face had similar identities. Our results are consistent with the existence of the continuity field for expression, a specialized mechanism that promotes the stability of emotion perception, which could help facilitate social interactions and emotion regulation.
