Upon a detailed psychological analysis of Thorndike's 'Law of Effect' under Connectionism, Pavlov's 'Stimulus Generalization' in Classical Conditioning, and Skinner's concepts of 'Cumulative Learning' and 'Shaping' in Operant Conditioning, which of the following statements most authentically explains the foundational and functional differences among these theories?

According to Thorndike's connectionism, learning occurs through the establishment of a bond between a stimulus and a response, where the 'Law of Effect' determines that satisfying outcomes strengthen the bond. In Ivan Pavlov's classical conditioning, stimulus substitution and stimulus generalization play major roles. In contrast, B.F. Skinner's operant conditioning focuses on voluntary behaviors where desired complex behavior is achieved through 'shaping' and schedules of reinforcement via successive approximations.
