Observer bias in scoring boys' and girls' aggression

In order to examine the possibility that the attribution of more aggression to boys may be in part a function of observer bias, 40 adults were asked in Study 1 to record the degree of aggression in a series of line drawings that showed children interacting. It was found that a significant subset of both males and females recorded more aggression for boys than for girls when they scanned scenes that showed numerous children interacting. When they rated a series of drawings of two children interacting, males rated boys as significantly more aggressive than girls. Study 2 examined 48 adults' responses under one of three instruction conditions. The findings of Study 1 were replicated. Additionally, it was found that some forms of instruction eliminate sex-typed biases while others yield significant biases among both male and female untrained observers. These results are interpreted in light of the literature on schematic processing. Implications pertaining to the socialization of aggression and to research on sex differences in aggression are discussed.     

Teacher and peer reactions to boys' and girls' play styles

Seventy children (35 boys and 35 girls) aged 24 to 30 months were observed in play groups consisting of 12–15 2- and 3-year-old children and two teachers. The social interaction was coded using an observation schedule which allowed for coding the children's behaviors and reactions to that behavior by others in the environment. The behavior scores were factor analyzed, using the complete sample of 180 children with six factors (play styles) resulting. Children who were high and low on each factor were examined to see if play style influenced the type of social reaction received. Children who preferred to work at tasks quietly received positive teacher feedback, but there was no change in peer interaction; children who engaged in active motor play received positive peer feedback, but negative teacher reactions. Children who were passive received less peer reaction and played alone significantly more than other children. Sex differences in reactions did not appear except when the child was engaged in male- and female-typical behaviors when examining scores on one factor only. When combinations of factors are examined (e.g., activity level and task performance), then different patterns of responses start to appear for boys and girls. The implications for differing patterns of social reactions to different play styles are discussed.Data analyses were supported by BRSG Grant RR07980 awarded by the Biomedical Research Support Grant Program, Division of Research Resources, National Institutes of Health. The final write-up was completed on a postdoctoral fellowship (Grant No. 1 T32 MH 16955-01) through the Oregon Social Learning Center.     

The impact of pressured information management on boys' and girls' psychological functioning

This study involving 463 adolescents examined the impact of pressured information management with mothers on boys' and girls' subsequent psychological functioning. This novel concept of pressured information management involved both pressured secrecy and disclosure and was defined as the degree to which adolescents feel they have no choice but to engage in these strategies. While pressured secrecy was especially aversive for girls, yielding associations with both depression and anxiety, it was related to stress only in boys. Pressured disclosure was less detrimental, and in fact, had a positive influence on girls' anxiety over time. Alternate models for these effects were considered but not supported by the data. Together, these findings highlight the importance of considering teens' reasons for engaging in different information management strategies and suggest adolescents who feel they have no choice but to keep secrets or disclose information to mothers may experience psychological consequences that are gender-specific.     

Genetic and environmental influences on girls' and boys' gender-typed and gender-neutral values

In this first investigation of genetic and environmental influences on children's values, 271 German twin pairs (50.2% boys) reported their values at ages 7-11 years using the Portrait Values Questionnaire (Schwartz & Rubel, 2005). We distinguished between gender-neutral (conservation vs. openness to change) and gender-typed (self-transcendence vs. self-enhancement) values. Boys differed from girls in the importance given to gender-typed benevolence, achievement, and power values. Gender-neutral values showed moderate (.34) and gender-typed values showed higher (.49) heritability, with nonshared environment and error accounting for the remaining variance. For both sexes, substantial genetic effects accounted for the importance children gave to their respective gender-stereotypical end of the self-transcendence versus self-enhancement dimension. However, dramatic sex differences emerged in the gender-atypical end of the distribution. For girls, low self-transcendence (high gender-atypical values) showed a large (.76) group heritability. For boys, gender-atypical values (high self-transcendence) showed no heritability and a modest (.10) shared environment effect.     

Sex differences in the effects of interest on boys' and girls' reading comprehension

This study compared the reading comprehension of groups of boys and girls (aged 10–11) on two tests, one of which was about the evacuation of children during the Second World War and the other of which was about spiders. These were the actual year 6 SATS reading tests administered in the UK in 1998 and 1999. The majority of the boys said that they would prefer to read the text about spiders, and the majority of the girls said they would prefer to read the text about leaving home in wartime. These patterns of preference were reflected in the children's performance on the actual tests. However, whereas the boys' comprehension was significantly affected by the content of the tests (they showed better performance on the test about spiders) the girls' performance was relatively little influenced by the content of the test. The implications of these results for testing reading, and for encouraging reading more generally, are discussed.     

Criteria of personal, boys', and girls' popularity as ranked by Greek adolescents

This study examined what Greek adolescents believe are the most important criteria of personal, boys', and girls' popularity in their age group. Participants were 364 students aged between 12 and 15 years. Seven main criteria of popularity were identified: sport competence, physical appearance, academic ability, being a good friend, being sociable, having a good sense of humor, and having the 'right circle of friends'. With regard to personal popularity, being a good friend and being sociable were the two most highly ranked criteria for both boys and girls across all ages. Boys and girls perceived differently the most important criteria of boys' and girls' popularity. Specifically, for same-sex popularity, being a good friend was the most highly ranked criterion, whereas for other-sex popularity, physical attractiveness was the most highly ranked criterion. The findings imply that friendship and social affiliation are the most important criteria of popularity in Greek adolescents.     

Five-month-old girls' and boys' exploratory behaviors in the presence of familiar and unfamiliar toys.

The exploratory behaviors of 60 5-month-old girls and boys were observed as they played with three unfamiliar toys and one familiar toy of their own during a laboratory session. Infants were seated at a table on the lap of an assistant. Each toy was placed on the table and remained there for 2 min after the infant first touched it. Frequency and duration of visual fixation on the toy, hand contact with the toy, five categories of lateralization, and eight categories of handling behaviors were measured. On the whole, the exploratory behaviors of girls and boys were not markedly different. However, girls spent more time than boys did in simultaneous hand contact with and visual fixation on their own familiar toy, whereas boys made more frequent contact with the familiar toy without visual fixation. In addition, boys displayed, overall, more tapping behaviors, and girls, more pinching and object-displacement behaviors. Girls and boys did not differ in manual lateralization. Results are discussed in reference to infants' rate of development, motor activity level, and girls' and boys' reactions to novelty.     

Ten-year-old girls' and boys' body composition and peer victimization experiences: prospective associations with body satisfaction

This study examined prospective associations between 10-year-olds’ weight and height, their perception of shape and stature, frequent experiences of peer victimization, and different aspects of body esteem at age 13. Participants were 474 girls and 400 boys participating in a two-wave longitudinal questionnaire study. Main results were that whereas actually being heavier built at age 10 was associated with girls’ increments in body dissatisfaction, the mere perception of being too heavy was associated with boys’ poorer body satisfaction. Also, boys who believed that they were too short were more dissatisfied at follow-up. Whereas frequent peer victimization had long-term associations with girls’ weight-esteem, teasing targeted towards appearance was associated with boys’ more negative beliefs about what others think about their appearance. Finally, participants had become significantly more dissatisfied at age 13, suggesting that this is a time in life when both girls and boys risk becoming increasingly critical towards their appearance.     

Naturalistic assessment of children's compliance to teachers' requests and consequences for compliance

Naturally occurring levels of teacher commands, child compliance to those commands, and positive and negative teacher feedback were studied in 19 teachers and 130 children in kindergarten through third grade. Seventy-five of the children had been identified as "making a good social adjustment" to school (high-rated) and 55 children were identified as "not making a good social adjustment" to school (low-rated). Results of intensive observation over a 4-wk period showed that: (a) individual teachers differed significantly in their overall use of commands; however, they did not differentially respond to high- versus low-rated children; (b) high-rated children were more likely to comply with commands than were low-rated children; (c) although the overall level of positive social consequences was extremely low, there was some indication that high-rated children were more likely to receive positive feedback for compliance than were low-rated children; (d) low-rated children received significantly more positive feedback than high-rated children for noncompliance; (e) teachers gave negative feedback for noncompliance at an equal level to both groups of children; and (f) although repeated teacher commands following noncompliance were equal across groups, low-rated children were exposed to significantly higher levels of repeated commands following compliance than were high-rated youngsters.     

Relations between forms and functions of aggression and moral judgments of aggressive transgressions

The present study sought to examine the influence of aggressive behavior, psychopathy, and gender on moral judgments of aggressive transgressions. A two-dimensional conceptualization of aggression was used, such that proactive relational aggression, reactive relational aggression, proactive physical aggression, and reactive physical aggression were treated as distinct subtypes of aggression and also as distinct subtypes of moral judgments of aggression. Participants were 421 emerging adults (215 women). Self-report measures of aggression, psychopathy, and moral judgments were collected. Peer-reports of aggression and psychopathy were obtained from a randomly assigned subsample of 73 participants (46 women) for validity purposes. Unique associations were found between subtypes of aggression and corresponding moral judgments of the same subtypes.     

Fundamental dimensions of social judgment: understanding the relations between judgments of competence and warmth

In seems there are two dimensions that underlie most judgments of traits, people, groups, and cultures. Although the definitions vary, the first makes reference to attributes such as competence, agency, and individualism, and the second to warmth, communality, and collectivism. But the relationship between the two dimensions seems unclear. In trait and person judgment, they are often positively related; in group and cultural stereotypes, they are often negatively related. The authors report 4 studies that examine the dynamic relationship between these two dimensions, experimentally manipulating the location of a target of judgment on one and examining the consequences for the other. In general, the authors' data suggest a negative dynamic relationship between the two, moderated by factors the impact of which they explore.     

Relationship between students' self-assessment of their capabilities and their teachers' judgments of students' capabilities in mathematics problem-solving

The study examined the judgments made by four seventh-grade mathematics teachers of their 107 students' competence in solving mathematics problems. Simultaneously, the 107 students made self-efficacy judgments about their capability in solving mathematics problems. The two sets of judgments were tested for predicting students' mathematics performance. Also, students' prior mathematics achievement was studied for its influence on both teachers' and students' judgments and students' mathematics performance. Teachers were asked to make judgments of each student for every mathematics problem solved. Results were consistent with prior research indicating that students' mathematics self-efficacy beliefs were highly predictive of their performance. Path analysis indicated that the mathematics teachers' judgments were also highly predictive of students' performance and self-efficacy. In turn, these variables predicted students' postperformance judgments. Combining students' self-efficacy judgments and teachers' judgments of students increased predictiveness for students' mathematics performance. Educational implications were also discussed.     

Individual differences in boys' and girls' timing and tempo of puberty: modeling development with nonlinear growth models

Pubertal development is a nonlinear process progressing from prepubescent beginnings through biological, physical, and psychological changes to full sexual maturity. To tether theoretical concepts of puberty with sophisticated longitudinal, analytical models capable of articulating pubertal development more accurately, we used nonlinear mixed-effects models to describe both the timing and tempo of pubertal development in the sample of 364 White boys and 373 White girls measured across 6 years as part of the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development. Individual differences in timing and tempo were extracted with models of logistic growth. Differential relations emerged for how boys' and girls' timing and tempo of development were related to physical characteristics (body mass index, height, and weight) and psychological outcomes (internalizing problems, externalizing problems, and risky sexual behavior). Timing and tempo are associated in boys but not girls. Pubertal timing and tempo are particularly important for predicting psychological outcomes in girls but only sparsely related to boys' psychological outcomes. Results highlight the importance of considering the nonlinear nature of puberty and expand the repertoire of possibilities for examining important aspects of how and when pubertal processes contribute to development.     

Adolescent girls' and boys' weight-related health behaviors and cognitions: associations with reputation- and preference-based peer status.

In this study, the authors examined associations between preference- and reputation-based peer status and weight-related behaviors and cognitions for both adolescent boys and girls. Sociometric measures of peer like-ability and peer-perceived popularity, as well as self-reported measures of body size, dieting behavior, and weight-related cognitions were collected from a sample of 441 adolescents in Grades 11 and 12. Results revealed weight-related cognitions for girls (concerning obesity) and boys (concerning musculature/fitness). Peer-perceived popularity, but not like-ability, was significantly associated with both boys' and girls' body size and dieting. Lower levels of popularity were associated with heavier body shapes for girls and with both thin and heavier body shapes for boys. Findings suggest that peer status is an important source of social reinforcement associated with weight-related behaviors and cognitions.     

Relations between social and emotional competence and mental health: a construct validation study

Researchers working fairly independently of each other have created numerous measures of social and emotional competence (SEC). These measures tend to correlate (sometimes highly) with each other and with measures of stressful events, suggesting potential redundancy. We evaluated which, if any, SEC variables predicted unique variance in social and mental health after controlling for other SEC variables in the study and the impact of stressful events. Three-hundred and thirty-one university students participated in an anonymous, cross-sectional study. We measured stressful events, and a wide variety of SECs, including: social problem solving skill (effective problem orientation, automatic processing, and problem solving), alexithymia (difficulty identifying and describing emotions; minimising emotions), effective emotional control (low rumination, high impulse control, high aggression control, low defensive inhibiting of emotions), and level of emotional awareness. We also assessed a variety of aspects of social and mental health (e.g. depression, anxiety, hopelessness, suicidal ideation, life satisfaction, social support). Covariance analyses revealed that all SEC measures except minimising emotions had significant incremental value over the other measures and over stressful events in predicting social and mental health. The optimal set of predictors differed depending upon the type of health predicted. These findings have important implications for the design of social and emotional intervention programs.     

Children's social competence, academic competence, and aggressiveness as related to ability to make judgments of fairness.

The relationship of 102 fifth and sixth graders' judgments of fairness with their academic and social competence and aggressiveness was studied. Children were given self-report and peer-nomination inventories measuring academic competence, social competence, and aggressiveness at a single point in time at the public school they attended. These measures were related to children's prediction of fairness on a distributive justice measure. Children who saw themselves as academically and socially competent scored higher on the distributive justice measure. Children whose peers saw them as less academically competent and more aggressive scored lower on the distributive justice measure. Analyses showed an association between children's academic competence, social competence, and aggressiveness scores and their scores on judgments of fairness.
