Positive Reinforcement Studies

Researchers study learning of a behavior through the use of operant conditioning. This type of learning involves associating the behavior with a consequence, which is a reward or punishment. If the consequence is a reward, it leads to reinforcement of the desired behavior. One type of reinforcement approach is positive reinforcement, where the behavior is rewarded with an artificial, natural, or social reinforcer. Studies using positive reinforcement as a tool can help tease out important details about neurological functioning associated with different behaviors.

This video reviews the concepts behind reinforcement studies by using an example of a man training a dog to sit. Following this, we look at a generalized procedure of positive reinforcement commonly used by behavioral researchers. This involves, training rodents to perform a behavior (lever press) to get a reward (food). Lastly, specific applications demonstrate how scientists use positive reinforcement to understand behavior.
