Our laboratory at O.S.U. is unique because it has a sophisticated computer-controlled cognitive-motor test battery. O.S.U. is one of seven universities supported by NIMH as part of its network of Research Units on Pediatric Psychopharmacology ("RUPPs"). Recently, Dr. Mike Aman reviewed the available cognitive test systems on behalf of the Autism RUPP Group. From this exercise, it became quite clear to us that we maintain what is probably the world's best system for assessing the cognitive-motor effects of psychotropic drugs in children, especially children with developmental handicaps.
