17 normal and 17 psychotic subjects, including schizophrenic, depressive, and delusional patients, were given a modified Arc-Circle Matching Test of spatial perception. There was no significant difference between the performance of the psychotic group and that of the control group in left-hand, right-hand, and total scores in this tactile test of spatial ability. Differences between males and females and between dextrals and non-dextrals were nonsignificant. Nevertheless, for all subjects, the left-hand scores were significantly superior to right-hand scores.
