To determine whether modeling of infant care by males would increase young boys' interest in babies, a study was conducted with up to 34 white, middle-class children who attended a university day care center and who ranged in age from 2 to 6 years. Procedures involved 3 days of pretest data collection, 4 weeks of treatment presentation, and 3 posttest observation days. Three white babies served as stimulus infants. Baseline data on children's attention to a playpen were gathered under three conditions (playpen empty, containing goldfish in a bowl, containing a baby). Modeling experiences were then implemented. A videotape showing a man caring for a baby was seen at least twice by boys over the age of 3.5. On three or four occasions, each older boy was shown a book depicting men interacting with and caring for babies. Younger boys and girls were also exposed to the videotape; however, girls and younger boys were not shown the book. To assess treatment effects, data were gathered with the playpen empty, with baby and children of all ages present, and with baby and only older children present. Results indicated that older boys' interest in a baby could be increased through modeling. (RH)
