Double Visual Learning in Split-Brain Monkeys

C. B. Trevarthen 1

1 Division of Biology, California Institute of Technology, Pasadena

Split-brain monkeys (with forebrain divided) were trained to perform two contradictory visual tasks simultaneously, one task being presented to each eye. Usually one cerebral hemisphere dominated, but in some cases the two halves of the brain learned simultaneously. Contradictory color discriminations showed interference or transfer of learning until mid-brain commissures were also sectioned. The more extensive surgery failed to prevent transfer of simple brightness discriminations.
