Another difference between the two forms of learning is that nonassociative learning is considered to be a more fundamental mechanism for behavior modification than those mechanisms involved in associative learning. This can easily be seen as we move through the animal kingdom. Habituation and sensitization are present in all animal groups, but classical and operant conditioning are not (Razran, 197 1 ) . In addition, the available evidence suggests that the behavioral and cellular mechanisms uncovered for nonassociative learning may serve as the building blocks for the type of complex behavior characteristic of associative learning (Groves & Thompson, 1970; Hawkins & Kandel, 1984; Razran, 1971).
2. T o discover at what stage of the learning process changes in these systems occur. 3. T o determine where in the brain (or nervous system) these neurochemical events occur. 4. T o establish the behavioral specificity of the changes. The methods employed by simple systems researchers are perhaps the most varied of the four strategies we have seen. In general, they focus less on behavior and emphasize the anatomical, electrophysiological, biochemical, and molecular techniques. T h e general approach is to study a behavior using the comparative method; to localize the site of the behavior using neuroanatomical techniques; and when the site(s) of behavioral change are located, to progress on to cellular and molecular analysis.
