Negative Practice Overcorrection is a specific form of overcorrection a behavior reduction procedure In this technique following an undesirable behavior the individual is required to repeatedly perform the incorrect or undesirable behavior The rationale is often to make the behavior aversive through satiation increase response effort or disrupt the response chain thereby decreasing its future likelihood In this scenario Slash intentionally playing the wrong chord 15 times in a row directly fits the definition of negative practice because he is repeating the specific error he made Positive Practice Overcorrection would involve repeatedly performing the correct behavior eg playing the correct chord 15 times after playing the wrong one Restitutional Overcorrection requires the individual to restore the environment to a state that is better than it was before the misbehavior occurred eg if he had broken something he would fix it and perhaps clean other areas Negative Reinforcement involves the removal or avoidance of an aversive stimulus following a behavior which increases the future probability of that behavior It is a strengthening consequence not a punishment or overcorrection procedure designed to reduce behavior
