5 tests tapping speed of psychomotor performance and 4 tests tapping quality of ideational activity were administered to 25 Egyptian schizophrenics, 15 males and 10 females, before, during and right at the end of reserpine medication. Patients showed significant improvement on 4 of the psychomotor tests and on 2 of the ideational tests. The results did not show any consistent tendency for improvement to increase in direct proportion to the amount of drug administered.
