Grounding (discipline technique)
Grounding, or house arrest, is a general discipline technique throughout the Western world, particularly in the Anglosphere of the United States and Canada, which restricts children or adolescents at home from going out or pursuing their favorite activities, except for any obligations (school, doctor's appointments, church services, etc.). Moreover, any positive reinforcement and anything the parents may define as "privileges" (phone, computer (except for schoolwork), television, toys, dessert, etc.) are often revoked.
