What type of conditioning occurs when a dog learns not to lunge forward due to the pain from a prong collar?

The scenario describes a situation in which a dog experiences pain from a prong collar when it lunges forward, leading to a learned behavior of refraining from lunging to avoid that unpleasant experience. This is an example of positive punishment, which refers to adding an aversive stimulus in order to decrease a behavior. In this case, the prong collar's pain serves as the aversive stimulus that discourages the lunging behavior.

Positive punishment does not involve the removal of a stimulus but rather introduces a stimulus that the dog finds uncomfortable or painful, which effectively teaches the dog to avoid the undesirable action of lunging. This technique is a form of corrective training used to modify behavior by associating it with an unpleasant outcome.
