When conducting a comparative study of the interrelationships between Thorndike's 'Law of Readiness' and Pavlov's 'Classical Conditioning Theory' alongside Skinner's 'Operant Conditioning', which of the following statements most subtly and accurately outlines the conceptual and philosophical difference between Thorndike's 'Law of Effect' and Skinner's 'Reinforcement Theory'?

According to Edward Thorndike's laws of learning, Thorndike's 'Law of Effect' states that responses followed by satisfying consequences are strengthened. Inspired by this, B.F. Skinner developed the concept of reinforcement in his 'Operant Conditioning', which increases the future probability of that behavior (response rate) through consequences received after the response. Thorndike's theory is based on S-R (Stimulus-Response), whereas Skinner's theory focuses more on R-S or operant behavior.
