All of the above seven processes, by which the inborn, hard-wired genetically programmed schema of social behavior is modified through the effects of experience, must involve some type of memory. In the first two processes, the conditional reflex and the image memory of approach and flight locomotion, the memory processes have received extensive study. The other five processes must also involve some type of memory. Olfactory memory (or imprinting) and the memory of object relations necessary for neophobia are still other memory processes which should be investigated more extensively. Memory of some type, although it has not yet been adequately characterized, must be involved in the learned aspects of taming and wildness; although the process may be related to habituation, it also possesses characteristics of imprinting and critical periods as well. Finally, the learning of multi-modal sensory systems for the releasing and directing of motor patterning mechanisms may represent a fundamental memory-like process which is basic to the functioning of the neocortex.

Most of the effects discussed here are located on the sensory or integrative side of the motivational systems of social behavior rather than on motor patterning mechanisms. In other words, most acquired aspects of offense and defense behaviors involve the modification of sensory filters, the formation of new projections, or the strengthening or inhibiting of previously existing projections of sensory filters, i. e., sensory analyzers.
