title: [Visual tracking disorders in schizophrenia. Review of the literature and methodological considerations].
abstract: Since Holzman expressed the hypothesis that eye-tracking dysfunctions might be a genetic indicator of schizophrenia, the researches on the performances of schizophrenics in eye-tacking tasks have been numerous. The correlation between the results of all these researches leaves little doubt on the existence of eye-tacking dysfunctions in schizophrenics. But these distrubances must be precised. Up to now, the studies have used tests that were too complex in their interpretation (pendulum test) and they have been limited to a global appreciation of eye-tacking. To take into account the psychological parameters that may interfere with success in this type of tests, the coming researches should focus on elementary eye-motor activities.
