Pavlov's Consideration of Such Phenomena as Generalization,differentiation,and Experimental Neurosis Led

Pavlov's consideration of such phenomena as generalization,differentiation,and experimental neurosis led him to conclude that:

A) learning is the result of excitatory processes in different specific locations in the brain.
B) learning is the result of separate excitatory and inhibitory processes which may interact in specific locations in the brain.
C) learning and memory must take place in just a very small part of the brain.
D) physiological explanations of learned behavior would have to be supported by purely psychological explanations and interpretations as well.
