Preference for novelty, as measured with an exploratory behavior paradigm, was compared in 8-month-old full-term and preterm infants of matched conceptional age. Subjects were 64 infants, 32 full term and 32 preterm, with 16 males and 16 females in each group. (Author/JH)

Eating rates (bites per interval) and other meal behaviors (number of chews, sips, talks with a neighbor, and chews per bite) were observed for 30 normal and 30 overweight white preschool children in their school cafeterias. The children ranged in age from 1 1/2 to 6 years. (JMB)

Two studies investigated two groups of young children at the ages of four and eight years, respectively. Subjects were required to solve a simple problem task by performing a response opposite to that demonstrated by an adult. Girls' performance was significantly worse than boys', regardless of the sex of the model. (Author/CI)

Examined connections between having a sister versus a brother and coming from a same-sex versus an opposite-sex sibling dyad, and sex-typing in adolescents' friendships. Findings suggested that sisters may learn control tactics from brothers that they apply in friendships. Boys were less likely to model emotional intimacy. Coming from opposite-sex…

When equated on level of maturity, preterm infants were indistinguishable from full-term infants in their rates of response decrement to stimulus repetition and their subsequent response to a novel stimulus. Responsiveness to auditory novelty at four months was a strong predictor of 18-month mental performance for females but not for males. (RH)

Play behaviors of 17 children enrolled in a discovery-based preschool program and 18 children in a formal program within a university center were observed over 11 weeks for 20 one-minute observations. (Author)

This study investigated the relative conformity of American and Brazilian students across ages from 9 to 21 years old. (Authors)

Results of cross-cultural comparisons of verbal responses indicate that social desirability has a higher value for Indian adolescents and activity has a greater value for American adolescents. Greater sex differences in self-perception occurred for Americans, and greater cultural differences for boys. (WY)

This study examined how children's play varied as function of child's sex, play partner's sex, and whether they played in dyads or groups. Observation data revealed that boys' same-sex play was more active-forceful, farther from presence of adults, and more stereotyped than girls', a pattern exaggerated in groups. Mixed-sex play was more likely…

Sex differences in responsiveness to infants were investigated by comparing the physiological responses of boys and girls in middle childhood and early adolescence with their overt behavioral reactions which were presumed to be more affected by societal norms. Results showed no sex differences on the psychophysiological measures but did reveal sex…

Using extensive, multifaceted observational and interview data from the Family Socialization and Developmental Competence Project (FSP), this paper examines the claims that androgynes, by comparison with sex-typed individuals, are more effective persons and parents. (Author/RH)

Examines the effect of three types of school environment (informal, intermediate, and formal) on changes in figural creativity over a school year for first- and second-grade children. (Author/RH)

Used prospective longitudinal design to examine peer rejection, aggressive behavior, and social withdrawal among 107 maltreated and 107 nonmaltreated children. Found that chronic maltreatment was associated with heightened risk of peer rejection from childhood to early adolescence. Aggression accounted largely for the association between chronic…

The verbal, performance, and full-scale IQs of the standardization sample for the Wechsler Intelligence Scale for Children--Revised (WISC-R) were analyzed according to sex, race, geographic region, parental occupation, and type of residence (urban or rural) and compared with corresponding data from a 1950 study of the WISC standardization sample.…

Mothers' ability to decode their children's nonverbal expressions of four affects (happiness, sadness, fear, and anger) was contrasted with the decoding ability of a matched group of nonmothers. Results indicate that mothers were accurately able to decode expressions of happiness but had relative difficulty with decoding expressions of sadness,…
