title: Opposite responding in two sense modalities.
abstract: Monkeys were trained to respond in one way to a pair of solid objects when discrimination was by touch; in the opposite way, when by vision. These opposite habits are formed independently and can be used concurrently. The finding suggests that the neural systems responsible for tactile and visual learning are separate, even with a single pair of objects.
