Recent neural evidence challenges the traditional view that face identity and facial expressions are processed by segregated neural pathways, showing that information about identity and expression are encoded within common brain regions. This article tests the hypothesis that integrated representations of identity and expression arise naturally within neural networks. Deep networks trained to recognize expression and deep networks trained to recognize identity spontaneously develop representations of identity and expression, respectively. These findings serve as a “proof-of-concept” that it is not necessary to discard task-irrelevant information for identity and expression recognition.
