有证据表明，人类系统处理面部表情的基础是两种类型的表达：一种依赖于身份，另一种独立于身份。我们最近提出的研究结果表明，身份依赖的表示编码使用原型参考方案，在一种方式，特别是类似于面部身份提出的。独立于身份的表征是否也是以这种方式编码的？我们调查了这一点，通过适应参与者的反表达，并要求他们分类的表达后效在原型探针是相同的（一致）或不同的（不一致）的身份适配器。为了区分编码方案，我们测量了后效幅度如何响应于适配器强度的变化而变化。增加后效应的幅度与适配器强度的原型参考编码的特点，观察到在两个一致的，至关重要的是，不一致的条件。我们的结论是，身份无关的表达表示确实使用原型参考方案编码。面部身份的编码和两种表达方式之间惊人的相似性提出了一种可能性，即原型参考编码可能是一种常见的方案，用于编码我们复杂的社会互动所需的多种类型的信息。
Evidence suggests that underlying the human system processing facial expressions are two types of representation of expression: one dependent on identity and the other independent of identity. We recently presented findings indicating that identity-dependent representations are encoded using a prototype-referenced scheme, in a manner notably similar to that proposed for facial identity. Could it be that identity-independent representations are encoded this way too? We investigated this by adapting participant to anti-expressions and asking them to categorize the expression aftereffect in a prototype probe that was either the same (congruent) or different (incongruent) identity to that of the adapter. To distinguish between encoding schemes, we measured how aftereffect magnitude changed in response to variations in the strength of adapters. The increase in aftereffect magnitude with adapter strength characteristic of prototype-referenced encoding was observed in both congruent and, crucially, incongruent conditions. We conclude that identity-independent representations of expression are indeed encoded using a prototype-referenced scheme. The striking similarity between the encoding of facial identity and both representations of expression raises the possibility that prototype-referenced encoding might be a common scheme for encoding the many types of information in faces needed to enable our complex social interactions.
