Behaviorism

Behaviorism is a psychological approach that explains learning through observable behavior and the relationships between stimuli and responses. It includes two forms of conditioning:

• Classical conditioning: A stimulus becomes associated with a response.
• Operant conditioning: Responses become more or less likely depending on their consequences, such as reinforcement or punishment.

Key Researchers and Experiments

Ivan Pavlov: Classical Conditioning

In the “dog and bell” experiment, food naturally caused a dog to salivate. Food was the unconditioned stimulus, and salivation was the unconditioned response. A bell initially produced no response, making it a neutral stimulus.

Pavlov repeatedly rang the bell before presenting food. Eventually, the bell alone caused salivation. The bell had become a conditioned stimulus, and salivation in response to it was the conditioned response.

John B. Watson: Behaviorism and Classical Conditioning

Watson argued that people are born with some reflexes and emotional reactions, while much of what they learn develops through stimulus–response associations.

In the “Little Albert” experiment, a baby initially showed no fear of a white rat. A loud noise was then made whenever the rat was presented. Albert came to fear the rat even without the noise. The video says Watson later reduced the fear by repeatedly presenting the rat without the loud noise.

Watson is credited with coining the term behaviorism.

B. F. Skinner: Operant Conditioning

Skinner examined how consequences affect the likelihood that a behavior will recur:

• Positive reinforcement: Rewarding a response makes it more likely to happen again.
• Negative reinforcement: A response that helps an individual escape something painful or unpleasant is more likely to recur.
• Extinction: A response that is no longer reinforced becomes less likely.
• Punishment: An unwanted response is discouraged or eliminated.

In the “rat in a box” experiment, a hungry rat received a food pellet after pressing a lever. The pellet reinforced lever pressing. When pressing the lever no longer produced food, the behavior eventually declined.

Implications for Education

From a behaviorist perspective, teaching is a structured process for shaping student behavior:

• Provide positive stimuli or rewards when students respond correctly.
• Respond to incorrect behavior with negative stimuli or by withholding positive reinforcement.
• Repeat the process as needed until the desired responses are learned.
