Abstract
This review puts into questions the possible role of cognitive vulnerability markers in prediction and prevention of schizophrenia. Until recently, none of the identified cognitive anomalies has been proved to be definitive. However, as new promising candidates are emerging (DS‐CPT, CPT‐IP, P suppression, Saccadic Eye Movements), the predictive value of these trait–type anomalies may be criticized regarding four issues, which are discussed: technical, metrological, theoritical, and clinical. As things stand, the existence of a cognitive vulnerability marker, which testify to a permanant pathological trait, does not constitute a suffisant factor to identify and treat subjects who are at risk for schizophenia. © 2002 Wiley‐Liss, Inc.
