Question

the law of effect most clearly influenced: pavlovs studies of conditioned salivation. skinners experiments on reinforcement. garcia and koellings research on taste aversion. watson and rayners findings on fear conditioning.

Explanation:

The law of effect states that behaviors followed by positive outcomes are likely to be repeated. Skinner's operant conditioning (experiments on reinforcement) builds on this. Pavlov's work is classical conditioning (stimulus - response association without direct outcome - based reinforcement). Garcia and Koelling's taste aversion is a form of classical conditioning with biological constraints. Watson and Rayner's fear conditioning (Little Albert) is also classical conditioning. Skinner's work (reinforcement) is most directly influenced by the law of effect.

Answer:

Skinner's experiments on reinforcement.
