Perspectives on prosopagnosia and models of face recognition.
The two papers by Bobes et al. (2003, this issue) and by Sperber and Spinnler (2003, this issue) add to the large body of literature demonstrating covert face recognition in prosopagnosia. This viewpoint will offer some perspectives on this interesting phenomenon. First, a re-analysis of the empirical literature will indicate an important misconception concerning the preserved abilities of prosopagnosics. The second section will briefly assess the contribution of Bobes et al. (2003, this issue) and Sperber and Spinnler (2003, this issue) to the debate about the locus, in cognitive terms, of the underlying causal deficit in prosopagnosia with covert face recognition. Both papers make reference to the two main models seeking to explain this phenomenon: the model proposed by Burton and colleagues (Burton et al., 1991; Burton and Young, 1999; Young and Burton, 1999) and that proposed by Farah and colleagues (Farah et al., 1993; O'Reilly and Farah, 1999). Finally, an observation will be offered concerning representations of faces in the Burton et al. (1991) model.
