Punishment for errors and visual-discrimination learning by monkeys with inferotemporal cortex lesions.

Abstract

Trained 3 normal monkeys and 6 monkeys with bilateral lesions of inferotemporal or foveal prestriate cortex on a series of 8 simultaneous visual discriminations. Training was accomplished (a) solely with positive reinforcers, or (b) with positive reinforcers and electric-shock punishment for errors. With training a, lesioned Ss made significantly more errors than normal Ss, the foveal prestriates being slightly more impaired than the inferotemporals. With training b, the inferotemporals were indistinguishable from the normals, whereas the foveal prestraite Ss made significantly more errors than either of the other groups.
