Question

Quizplus · Accepted Answer

The law of effect states that behaviors that are followed by positive outcomes or reinforcement are strengthened and more likely to occur in the future. Conversely, behaviors that are followed by negative outcomes or punishment are weakened and less likely to occur in the future. Therefore, choice A is the best answer as it accurately describes the law of effect. Choice B is incorrect as the law of effect is related to operant conditioning, not classical conditioning (which involves the CS and CR). Choice C is partially true, but only describes the process of acquisition (when the CR is first learned), not extinction (when the CR disappears). Choice D is also incorrect as the rat will only press the lever if it is previously associated with some type of reinforcement.
