Evidence that children and adolescents have internal models of peer interactions that are gender differentiated.

This study examined whether children's internal representations reflect gender differences that have been found in peer interactions. The dimensions examined were (1) preferences for dyadic or group situations, (2) whether children who are friends with a given target child are likely to be friends with each other, and (3) perceptions of the probability of knowing information about friends. Participants from preschool; grades 2, 6, 8, and 10; and college (N = 278) were asked questions about typical girls and boys. Results indicate that both girls and boys (1) rate typical boys as preferring group interactions more than do typical girls, a difference present as early as preschool; (2) rate typical boys as more likely than typical girls to be friends with one another if they are friends with the same target boy or girl respectively; and (3) rate typical girls as more likely than typical boys to know certain types of information about friends. These results are consistent with the existence of internal models of social interactions that are at least partially gender specific.

The influence of group size on children's competitive behavior.

The present research was designed to test the hypothesis that children would compete more in tetrads than in dyads. Twenty-two pairs of male and 14 pairs of female target children (N = 72) played a competitive game in both tetrads and dyads. Consistent with the hypothesis, male target children competed more in tetrads than in dyads. This hypothesis was not supported for females, however. Analyses of the dynamics of tetrads and dyads further demonstrated that based on a global measure of smiling, the emotional atmosphere was less positive in tetrads than in dyads. The causes and consequences of interaction in different sized social groups are discussed.

Beyond intimacy: conceptualizing sex differences in same-sex friendships.

This study was designed to replicate and extend prior findings that same-sex friendships of women and men are equally important but that women's friendships are more intimate. A group of adolescents and a group of adults were asked to complete an anonymous questionnaire regarding the quality of their close friendships, the degree to which they would support a close friend in times of difficulty, and the degree to which they would celebrate with a friend in times of success. Results demonstrated that both females and males saw and spoke with their close friends and were equally willing to confront and trust their close friends. Females, however, reported more desire to spend time with a close friend in times of difficulty and to celebrate with a close friend who had just experienced a positive event. Results are discussed in terms of the differing functions of women's and men's same-sex friendships and women's greater general interest in and attention to transitions in the lives of other individuals.

Characteristics of children who interact in groups or in dyads.

Little research within the field of developmental or educational psychology has addressed teachers' perceptions of the characteristics of children who interact in different types of peer organizations. This study was designed to examine teachers' perceptions of the characteristics of boys and girls who interact in groups or in dyads. Participants (teachers and children) were recruited from 10 classes from all grade levels of 2 elementary schools. The children were asked to name those in their classes who played together frequently. On the basis of participants' responses, 2 categories of target children were identified: those who played with at least 3 other children (group) and those children who played with 1 other child (dyad). Two teachers then rated each target child on 6 characteristics. The results indicated that, compared with children who played in dyads, target children who played in groups were rated by teachers as being more competitive, receiving more attention from peers, valuing their friends more, and being more emotionally expressive. No differences were found between target children who played in groups or dyads in empathy or self-confidence. In addition, no interaction between sex and type of social organization was found for any of the measures. Results are discussed in terms of the relation between social organization and functions of peer relations.

Sex differences in neonates' cuddliness.

The authors undertook the present study to determine whether under ecologically valid, low-stress conditions, female and male neonates could be differentiated on cuddliness. Sixteen female and 15 male neonates were videotaped interacting briefly with both a female and a male adult who were blind to the sex of the neonate. Raters coded degree of cuddliness and activity level. Results showed that raters could discriminate the sex of the neonate on the basis of degree of cuddliness. Discussion focuses on the importance of theoretical and methodological considerations in assessing sex differences in behavioral characteristics of neonates.

Sex differences in children's investment in peers.

It is hypothesized from within an evolutionary framework that females should be less invested in peer relations than males. Investment was operationalized as enjoyment in Study 1 and as preference for interaction in Study 2. In the first study, four- and six-year-old children's enjoyment of peer interaction was observed in 26 groups of same-sex peers. Girls were rated as enjoying their interactions significantly less than boys. In the second study, six- and nine-year-old children were interviewed about the individuals with whom they spend time in their homes and neighborhoods and about the individuals who participate in their favorite activities. The proportion of individuals named by children who were peers was significantly lower for girls than boys both in children's neighborhoods and in children's favorite activities. Results strongly support the hypothesis that females and males have evolved differential preferences for interaction with peers.

Age and sex differences in dyadic and group interaction.

This study examined age and sex differences in dyadic and group interaction in a standardized setting. Seven classes of 4-year-old children and 6 classes of 6-year-old children participated. From these classes, 13 male playgroups and 13 female playgroups were formed. The playgroups were videotaped, and frequencies of dyadic and group interaction were tabulated. Results showed that boys and girls at both ages engaged in similar frequencies but different patterns of dyadic interaction. Only 6-year-old boys, however, interacted in groups. The discussion considers the etiology of these age and sex differences.

Greater preference among females than males for dyadic interaction in early childhood.

The present study was designed to examine sex differences in children's preferences for dyadic and group interaction in early childhood. In Study 1, a professional puppeteer interacted with 21 females and 20 males 4 and 5 years of age using 1 (dyad) and 3 (group) puppets in a within-subjects design. Enjoyment of the 2 conditions was assessed through frequency of smiling and eye contact. In addition, sociometric techniques were used to measure the size of children's play networks, and observations of naturally occurring dyadic and group interaction were conducted. Study 2 was a replication of the puppet play procedure used in Study 1 with 38 females and 37 males 3 and 4 years of age. In both studies, females were found to enjoy dyadic interaction more than males. In addition, some evidence suggests that males may enjoy group interaction more than females. Results are discussed in terms of theoretical explanations for sex differences in preferences for interaction with differing numbers of peers.

The development of trait explanations and self-evaluations in the academic and social domains.

The present study was designed to investigate the development of children's trait explanations and self-evaluations in the 2 domains. 144 white, middle-class children in kindergarten, first, second, and fourth grades (mean ages 5-8, 7-0, 7-9, and 10-0 years, respectively) were interviewed individually about their explanations for both academic and social outcomes and their evaluations of their own outcomes. Trait explanations emerged earlier in the social domain. In addition, trait explanations emerged earlier for success than for failure. Self-evaluations became less positive in both domains and less similar across domains with increasing grade level. An experiential theory of the development of understanding of a domain is presented.
