On the Intensity measure of the Grid Test acute and chronic thought disordered schizophrenics were significantly different from controls, and acute non-thought disordered schizophrenics significantly different from acute thought disordered schizophrenics. The difference between chronic thought disordered and non-thought disordered schizophrenics just failed to reach the 10% level of significance. On the Consistency measure results were variable. Only the acute non-thought disordered schizophrenics were significantly different from the acute and chronic thought disordered schizophrenics. The findings are discussed.
