Found that 75 percent of variance in children's first-grade achievement was predicted by measures of their achievement, object play, and peer interaction in kindergarten; and that aspects of first graders' personality disorders and aggressive behavior were predicted by their popularity in kindergarten.

Using an experimental design that avoided some methodological difficulties of earlier studies, this study found a relationship between harsh parental discipline and kindergarten children's aggression. This relationship was apparently not a result of confounding factors such as child temperament, SES, and marital violence. (BC)
