In operant conditioning, what effect does partial reinforcement have on responses compared to continuous reinforcement?

• A. Faster acquisition and quicker extinction
• B. Slower acquisition and more resistance to extinction
• C. Uniform response outcomes
• D. Higher response variability

Answer: (B)

Partial reinforcement refers to a reinforcement schedule in which not every response is followed by a reinforcement, as opposed to continuous reinforcement, where every response is reinforced. This difference influences the dynamics of learning and the durability of the learned behavior. When an organism experiences partial reinforcement, the acquisition of the desired behavior tends to be slower. This is because the inconsistency in reinforcement can create uncertainty, making the subject less likely to quickly learn the association between the behavior and the outcome. However, once the behavior has been established, the responses tend to be more resistant to extinction—meaning that when reinforcement is no longer provided, the behavior persists longer than it would under continuous reinforcement. This resistance to extinction arises because the lack of consistent reinforcement in partial schedules creates an expectation that the reinforcement could still occur, leading to a higher likelihood of the behavior continuing even when the reinforcement is removed. In contrast, with continuous reinforcement, once the reinforcement stops, the subject quickly realizes that the behavior will no longer be rewarded and tends to stop the behavior altogether. Therefore, the correct understanding of how partial reinforcement affects responses is that it leads to slower acquisition of the behavior initially but results in greater resistance to extinction once the behavior has been established.
