In Skinner's view, what role does reinforcement play in learning?

B is the correct answer because, in Skinner's behavioral theory, reinforcement is a fundamental concept that is essential for encouraging and establishing desired behaviors in learners. Skinner proposed that when a behavior is followed by a reinforcing stimulus, such as a reward or positive outcome, the likelihood of that behavior being repeated in the future increases. This process is part of operant conditioning, which explains how behaviors can be shaped through reinforcement.

Reinforcement can be positive, where a desirable stimulus is presented following a behavior, or negative, where an undesirable stimulus is removed, both leading to an increase in the frequency of the desired behavior. This principle applies not only to learning in a broad educational context but also spans across various stages of development, reinforcing the idea that well-timed rewards can effectively motivate and instill positive behavior in individuals of all ages.

Understanding the significance of reinforcement can help educators create effective learning environments that encourage student engagement and participation, making it a key aspect of Skinner's contributions to educational psychology.
