Answer:
Grounding Larry is an example of negative punishment.
Explanation:
In Operant Conditioning, punishments are used in order to decrease a specific conduct. These can be either negative (removing a pleasant stimulus) or positive (adding an aversive stimulus).

The grounding is used to decrease his behavior which does after a few times of being grounded.
