Final answer:
The correct option is B. the law of effect.
The law of effect states that behaviors followed by satisfying consequences are more likely to be repeated, while behaviors followed by unpleasant consequences are less likely to be repeated.
Step-by-step explanation:
The statement that when an action results in a pleasurable consequence, the probability of repeating that action increases best illustrates the law of effect.
The law of effect, first proposed by psychologist Edward Thorndike, states that behaviors that are followed by satisfying consequences are more likely to be repeated, while behaviors followed by unpleasant consequences are less likely to be repeated. This principle is based on the idea that learning is influenced by the positive or negative outcomes or consequences of our behavior.
For example, in the workplace, if we receive a positive outcome in the form of a paycheck for showing up to work, we are more likely to continue showing up. On the other hand, if we stop receiving a paycheck, we may be less motivated to continue working, even if we enjoy our job.
