Best of luck to all and hope these help. Learning: the process by which experiences change our nervous system and therefore our behavior. Memory are these changes in our nervous system; alterations in neural circuits that participate in perceiving, performing, thinking, and planning. Four types of learning : perceptual learning: learning to recognize a particular stimulus that has been perceived before. Primary function: the ability to identify and categorize objects and situations. Each sensory system is capable of perceptual learning. Accomplished primarily by changes in the sensory association cortex: stimulus-response learning: learning to automatically make a particular response in the presence of a particular stimulus. Involves establishing connections between circuits involved in perception and in movement. Can be either an automatic response like a defensive reflex or a complicated sequence of movements. Two major categories: classical conditioning: a learning procedure in which an unimportant stimulus acquires the properties of an important one.
