When should grown Ups stop fights? (1955)

Vassar College's Department of Child Study produced this training film for nursery school staff, one of a series on "Preschool Incidents." Unstaged playground scenes of two to five-year-olds in conflict are shown, then repeated for further analysis and discussion. We learn how to "size-up situations," differentiating between "playful attacks" the kids can adequately handle themselves and truly aggressive behavior (as when "a child has gone on a rampage") that requires immediate adult intervention.
