In learning a black-white discrimination response, the efficiency of rhesus monkeys with lesions of the anterior frontal cortex varies inversely with the spatial separation of the discriminative stimuli from the places of response and reward. Though there is a similar relationship in intact animals, impairment of learning due to discontiguity is greater in the animals with brain lesions.
