Parents will probably be arguing from here to eternity over whether or not to spank misbehaving toddlers. But the age-old debate misses the point: It matters less whether you bare the rod or send Johnny to his room, says a Boys Town psychologist, than explaining why you're doing it. Even for preschool kids, it's reasoning that makes any punishment most effective.
Robert E. Larzelere, Ph.D., had 40 mothers keep a month-long record of all their toddlers' infractions, whether fighting with siblings or disobeying parents. The accuracy of the records was aided by recording devices placed (with consent) in their homes. Lafzelere and a colleague, William N. Schneider, Ph.D., calculated the time between bouts of misbehavior.
The results: Reasoning alone was equally as effective as punishment alone-whether time-out, revoking privileges, hand-slapping, or non-abusive spanking. Both kept fighting at bay for nine hours. But when reasoning was used with any kind of punishment, it more than doubled the delay between fighting episodes to 19.8 hours.
