The law of effect laid the foundation for:

- Garcia and Koelling's research on taste aversion.

- Pavlov's studies of conditioned salivation.

- Skinner's experiments on reinforcement.

- Watson and Rayner's findings on fear conditioning.

Answer: Skinner's experiments on reinforcement.

Explanation: The law of effect, formulated by Edward Thorndike, is a law on behavioral court behavior. According to this law, the responses that are followed (contiguous) with reinforcing consequences will be associated with the stimulus and will be more likely to occur when the stimulus reappears.

On the contrary, if the response to the stimulus is followed by an aversive consequence, the association will be weaker, so the probability of occurrence will be lower. However, he had to revise this theory since in practice, the aversive consequence did not fulfill the purpose of weakening the connection between stimulus and response but rather seemed to have some consequences of pleasure instead of manifesting the response for that purpose.
