ABSTRACT
Though they are closely related, sensation and perception are different. Sensory information may determine response in quite different ways. The information may be transmitted directly to muscle and gland, or it may be transmitted instead to the higher centers of the cortex and have its effect only by making changes in the activity that is going on at that cortical level. In the first case, the behavior is sense-dominated and does not depend on perception. In the second, the sensory information affects behavior only in conjunction with the concurrent cortical processes. Very often it has no immediate effect on behavior, but produces latent learning that may or may not have an effect at some later time.
