Performance and reminiscence of brain-damaged, behavior-disordered, and normal children on four psychomotor and perceptual tests.

The hypotheses that normal children accumulate less reactive inhibition than brain-damaged and behavior-disordered 5s and that brain damage produces extraverted behavior were substantially supported by the results of 4 psychomotor and perceptual tests. 75 children (25 brain damaged, 25 behavior disordered, and 25 normals) of at least average intelligence (age range 11-15) were sampled. The results revealed normal Ss with less reminiscence effects, on 2 of the 4 tests, than the other Ss. Also, the normal 5s had better performance levels on all 4 tests. The brain-damaged 5s had performance and reminiscence effects similar to those of behavior-disordered 5s. A discriminate function analysis correctly classified 84% of the 5s.
