Answer:
B. Decreases
Step-by-step explanation:
According to differential reinforcement theory, one of the social learning theories, when behaviors are rewarded with the certain positive actions or positive outcomes then it is called positive enforcement. Positive enforcement increases the criminal actions. On the other hand, negative enforcement increases the actions which reduce the criminal activities.
According to theory explained above Studies have shown that viewing violent actions in the media decreases the inhibition against performing those actions when behavior is rewarded with the positive enforcement.
