Recent studies on parental disciplinary practices focus on children's attributes that influence harshness of discipline. The present study examined the effects of facial babyishness on parents' recommendations regarding the discipline of 4- and 11-year-old children who had perpetrated an act of commission or of omission. It was predicted that the actions of babyfaced children would be perceived as less intentional, and that babyfaced children would be punished less harshly than their maturefaced counterparts. A total of 32 mothers and 32 fathers of 10- to 12-year-old children participated. Each parent read eight vignettes describing either 4- or 11-year-old children's misdeeds. Attached to each vignette was a black-and-white photograph of a child, who had been rated as either babyfaced or maturefaced by introductory psychology students. As predicted, the misdeeds of babyfaced children were perceived as less intentional than those of maturefaced children. The severity of punishment recommended revealed "an age X facial babyishness interaction." Less severe punishment was recommended for babyfaced than maturefaced 4-year-olds. However, babyfaced 11-year-olds were punished more harshly than maturefaced ones. It is concluded that the findings have implications for parents and parent education. (Author/RH)
