Upon a micro-analysis of the theoretical and functional systems of Edward Thorndike's 'Connectionism' or 'Trial and Error Theory', Ivan Pavlov's 'Classical Conditioning', and B.F. Skinner's 'Operant Conditioning' within the scope of educational psychology, which of the following statements is most authentic and scientifically true regarding Stimulus-Response (S-R) and Response-Stimulus (R-S) relationships?

Understanding Learning Paradigms

In learning theories, Edward Thorndike's Connectionism and Ivan Pavlov's Classical Conditioning primarily operate on the 'S-R' (Stimulus-Response) framework, where a specific stimulus elicits a specific response from the organism.

In contrast, B.F. Skinner's Operant Conditioning is based on the 'R-S' (Response-Stimulus) paradigm, where the organism emits a spontaneous response (operant), and the subsequent reinforcement determines the probability of that response's recurrence.

• Thorndike: S-R bond formation through trial and error.
• Pavlov: S-R pairing of conditioned and unconditioned stimuli.
• Skinner: R-S (Response followed by Reinforcement) mechanism.
