Compares a group of 32 toddlers with employed mothers with a matched group of 38 toddlers with nonemployed mothers in order to examine the effect of maternal employment on the development of the child. While no differences were found between the two groups in language development and emotional adjustment, children of employed mothers were more…

Parental agreement was found to be more implicative for the psychological functioning of boys than girls and was positively related to the development of ego control in boys but negatively related to the development of ego control in girls. (Author/MP)

Employs an aggregate longitudinal approach to test the hypothesis that undesirable economic change leads to increased child maltreatment. Cross-correlational data over a 30-month period reveal that increases in child abuse are preceded by periods of high job loss. (Author/MP)

The dyadic interaction of popular and unpopular children was compared. Analysis revealed that unpopular children were more disagreeable and less likely to provide a general reason or rule for their disagreement or to suggest a constructive alternative when criticizing a peer. (Author/MP)

This 16-month longitudinal study examined effects of time, classroom program, and child gender on play behaviors of preschoolers attending a formal education program or a discovery program. Analysis revealed that dramatic interactive play and transformational behavior increased, while constructive play decreased. Boys in discovery classroom…

Teacher behaviors toward hyperactive boys on methylphenidate (ritalin), toward hyperactive boys on placebo, and toward normal comparison peers were compared. Teachers were more intense and controlling toward hyperactive boys on placebo, but no differences emerged between comparison and medicated groups. Need for broader monitoring of treatment…

Studied two factors hypothesized to be related to sex differences in participation in mathematics courses -- teachers' evaluative feedback and students' success expectations. No sex differences were found in patterns of teachers' evaluative feedback or students' success expectations on familiar mathematics tasks; however, girls had lower success…

Development of gender understanding in preschool age children was studied over eight months. Understanding appeared to follow an orderly sequence according to the person referred to: first, when the self was the referent; second, when a same-sex other; third, when an opposite-sex other.

Examined the relation between the spontaneous occurrence in play of simple two-part action sequences and the frequency of these sequences and their components following modeling at 12, 15, and 19 months of age. Play following modeling was typically more advanced but only 19-month-old children generally were able to imitate complete sequences.…

Modeling and direct instruction were used to train children to cooperate rather than compete. Children in treatment conditions showed significantly more cooperation than did control groups after immediate assessment. Seven weeks later age but not treatment differences were observed in generalization of training. (Author/DB)

Tested whether intrinsic motivation depends on matching cognitive level and task demands and assessed effects of rewards and praise on intrinsic motivation. Children preferred tasks just beyond their ability levels. Praise had mixed effects: rewards decreased intrinsic motivation among highly motivated children but did not influence intrinsic…

Examined judgments of intolerance given by children, adolescents, and adults toward disagreeing others. The evidence suggested that intolerance may be a lower level of reasoning in a social cognitive developmental progression. (Author/DB)

This longitudinal study (1) replicated research findings that there is a sex difference in the relationship between early mother responsiveness to children's requests for attention and later assessments of children's agentic behavior, and (2) reassessed differences in maternal responsiveness to boys versus girls. (Author/DB)

Studied effects of strategies used by mothers to prepare a two-year-old child to be left with a stranger. Strategies differed, as did outcomes. Among the results, children given brief preparations remained with the stranger longer and played with more toys. (Author/DB)

The distressed vocalizations of six-month-old infants interacting with peers in a playroom were statistically independent of the peer's vocalizations of distress. Absence of toys reliably predicted the extent of the infant's distress, whereas psychomotor development and sex did not. (Author/ DB)
