Not sure if there is a cultural difference. In our family it is considered normal to frighten the child so that he behaves the way we want.
Example-
Parent: Eat that quickly or the God will punish you!
Parent: Don't go on the stairs. The ghost is hiding there and it'll catch you!
Parent: Be quiet or the police will grab you!
Does this kind of behavior from the parent's side has any abnormal effects on the baby in the longer run? Can this behavior be accepted as normal?
Has any research been done on this aspect?
