ABSTRACT
Individuals with congenital or developmental prosopagnosia (CP/DP) find it hard to recognize faces. The severity of face and object recognition deficits appears to be correlated across individuals. The data reviewed by J. Geskin and M. Behrmann (G&B) come from behavioural tests of face and object recognition, and inferences drawn from such tests can always be challenged on methodological grounds. To demonstrate links or dissociations between face and object recognition deficits in CP, it is equally important to agree on an analogous set of test procedures for the assessment of object recognition abilities. In spite of the methodological caveats associated with interpreting behavioural data from face and object recognition tests, it is difficult to dispute G&B’s main conclusion that many CPs also have problems in recognizing non-face objects. The literature review conducted by G&B is certain to stimulate discussion about the profile of impairments that is typically found in CP, and about the modular versus domain-general nature of face and object recognition.
