知觉后效表明，在成年人的身份表征和表达相互独立的程度上存在不对称性。他们的表达表征是身份依赖的；当适应刺激和测试刺激具有不同的同一性时，表达后效的幅度减小。相反，他们的身份表征是独立于表达的；认同后效的大小与适应刺激和测试刺激是否产生相同的表达无关。与成人一样，儿童的表达表征是身份依赖的（Vida & Mondloch, 2009）。在这里，我们调查了他们是否有表情依赖的面部身份表征。成年人和8岁儿童（每组20人）在观看了显示相同或不同情绪表达的适应性刺激后，将面孔分类为身份连续体（苏/珍）。两组都表现出不受面部表情影响的身份后遗症。我们的结论是，与成人一样，8岁儿童的身份表征是独立于表达的。
Perceptual aftereffects have indicated that there is an asymmetry in the extent to which adults' representations of identity and expression are independent of one another. Their representation of expression is identity-dependent; the magnitude of expression aftereffects is reduced when the adaptation and test stimuli have different identities. In contrast, their representation of identity is expression-independent; the magnitude of identity aftereffects is independent of whether the adaptation and test stimuli pose the same expressions. Like adults, children's representation of expression is identity-dependent (Vida & Mondloch, 2009). Here we investigated whether they have an expression-dependent representation of facial identity. Adults and 8-year-olds (n = 20 per group) categorized faces in an identity continuum (Sue/Jen) after viewing an adapting stimulus that displayed the same or a different emotional expression. Both groups showed identity aftereffects that were not influenced by facial expression. We conclude that, like adults, 8-year-old children's representation of identity is expression-independent.
