‘Behavior of young children in a situation simulating entrapment in refrigerators was studied in order to develop standards for inside releasing devices, in accordance with Public Law 930 of the 84th Congress.
Using a specially designed enclosure, 201 children 2 to 5 years of age took part in tests in which six devices were used, including two developed in the course of this experiment as the result of observation of behavior.
Success in escaping was dependent on the device, a child’s age and size and his behavior. It was also influenced by the educational level of the parents, a higher rate of success being associated with fewer years of education attained by mother and father combined. Three major types of behavior were observed: (1) inaction, with no effort or only slight effort to get out (24%); (2) purposeful effort to escape (39%); (3) violent action both directed toward escape and undirected (37%).’
