Abstract
An Objective Test Battery composed of five objective tests was administered to seventy-nine testees. These seventy-nine testees consisted of twelve normal subjects and sixty-seven consecutive admissions to the Saskatchewan Hospital, North Battleford. On the results of the various tests a number of diagnostic criteria were selected and their predictive value examined. Differences between the mean criteria scores of the three groups, Normal, Neurotic and Schizophrenic were statistically significant at the .01 level. Differences between the mean criteria scores of the Other Psychotic group were not significantly differentiated from both Schizophrenics and Neurotics.
