• Resumen

  • The aim of this study was to clarify the relationship between accessing the identity of a face and making decisions about its expression. Three experiments are reported in which undergraduate subjects made expression decisions about familiar and unfamiliar faces. The decision was slowed either by concealing the mouth region with a black rectangle (experiment 1) or by using a short presentation time (experiments 2 and 3). Results of experiment 1 showed that subjects recognized the displayed expression of celebrities better than those of unknown persons when information from the mouth was not available. Results of experiment 2 showed that they recognized the expression displayed by celebrities more easily when the presentation time was short. Experiment 3, using familiarized faces, replicated the results of experiments 1 and 2 and ruled out a possible explanation of these results by the use of some identity specific representations that are expressive. Implications for face recognition models are discussed.
