Synopsis

The extent to which the second member of a pair of monotic clicks facilitates simple reaction time was examined for 35 psychiatric patients and 43 non-patient controls across 2 studies. Affective psychotic patients showed greater reaction time facilitation than did either schizophrenic patients or non-patient controls. Computer simulations of a ‘statistical facilitation’ model for these data are also presented.
