What is a positive reinforcer?

A positive reinforcer is defined as a stimulus that is presented following a certain response, which then increases the likelihood of that behavior being repeated in the future. In the context of behavior modification, positive reinforcement is an effective strategy used in training animals; it encourages desirable behavior by providing a reward immediately after the desired action occurs.

For example, when training a dog, giving a treat or praise right after the dog sits on command serves as a positive reinforcer. The treat or praise strengthens the association between the action (sitting) and the positive outcome (receiving a reward), leading to an increased probability that the dog will sit when commanded in the future.

This understanding assists in behavior management within veterinary practice, where rewarding animals for calm behavior during examinations or procedures can lead to improved cooperative behaviors in the future.
