In positive punishment, you add an undesirable stimulus to decrease a behavior. … In negative punishment , you remove a pleasant stimulus to decrease a behavior. For example, when a child misbehaves, a parent can take away a favorite toy. In this case, a stimulus (the toy) is removed in order to decrease the behavior.
Positive punishment is when you add a consequence to unwanted behavior. You do this to make it less appealing. An example of positive punishment is adding more chores to the list when your child neglects their responsibilities.
Losing access to a toy, being grounded, and losing reward tokens are all examples of negative punishment. In each case, something good is being taken away as a result of the individual’s undesirable behavior.
The major similarity between the two is that both of them are types of the same concept of Operant Conditioning, Punishment. Also, both of these types work to decrease any undesired behavior from the individual.
