The effects of sex differences and evaluation on task performance and aspiration

An investigation was conducted of how evaluation differentially affects the performance and aspiration for future performance of 118 high school boys and girls. Subjects were selected to fit into either a superior or average intelligence group. In the high evaluation condition, subjects were instructed that their intelligence was being evaluated in anagram and visual-motor tasks they performed, while those in the low evaluation condition were instructed that the two tasks were being correlated. It was hypothesized that on a highly evaluated task, girls, when compared to boys, would show greater performance debilitation and would have lower aspirations for future performance. Although sex differences were found in performance debilitation and aspiration for future performance, they were not all in the predicted directions. Girls were equally debilitated in anagram performance under both evaluation conditions, while boys were debilitated in anagram performance only under high evaluation. When both boys and girls demonstrated a performance debilitation on the anagram task, their performance declined approximately 10%. No sex differences in performance were found on the visual-motor task. On both tasks, girls' aspirations were significantly affected by evaluation condition. The girls averaged 89% choosing the more difficult task in the low evaluation condition. Evaluation condition had no significant effect on aspiration for boys on either task. Intelligence showed no significant relationships.     

Music and Video as Distractors for Boys with ADHD in the Classroom: Comparison with Controls,Individual Differences,and Medication Effects

This study examined the effects of music and video on the classroom behavior and performance of boys with and without attention deficit hyperactivity disorder (ADHD) and examined the effects of 0.3 mg/kg methylphenidate (MPH). In one study, 41 boys with ADHD and 26 controls worked in the presence of no distractor, music, or video. Video produced significant distraction, particularly for the boys with ADHD, and MPH improved the performance of boys with ADHD across distractor conditions.There were individual differences in response to the music such that some boys were adversely affected and others benefited relative to no-distractor.In a second study, music and MPH were assessed in an additional 86 boys with ADHD to examine further the music results. In the presence or absence of music, MPH improved performance relative to placebo. Similar individual differences were found as in Experiment 1.     

Attention-deficit hyperactivity disordered boys' evaluations of and attributions for task performance on medication versus placebo

The present study examined the effects of stimulant medication on the self-evaluations of and attributions for task performance of 26 attention-deficit hyperactivity disordered boys. Each boy performed a continuous performance task twice, once while on medication and once while on placebo. Immediately following the completion of the task, the boys were asked a series of questions concerning their self-evaluations of, and attributions for, their performance. Two findings of note were obtained. First, medication, compared with placebo, increased the correspondence between the boys' self-evaluations and their performance. Second, the boys did not use medication as a frequent explanation for their performance, as others have predicted. In fact, the boys picked medication as an explanation for their successes significantly less often than either effort or ability.     

Problem-solving performance of young boys and girls as a function of task appropriateness and sex identity

The problem-solving performance of young boys and girls was examined in three conditions in which good performance was indicated as being appropriate for boys, for girls, or for both boys and girls. The relations between task scores and five sex-role measures were also examined. As predicted, the boys performed significantly more poorly when the task was indicated as one that girls did better. The girls' performance was not affected by the conditions of the study. The girls' problem-solving scores did not differ significantly from the boys' scores. There was some relationship between the task scores and the sex-role measures for boys, but not for girls. Associations among the sex-role measures were not high.This research was supported by a DGES-FCAC research grant from the government of Quebec, Canada.     

The effects of a graduated stimulus change on the acquisition of a simple discrimination in severely retarded boys

Methods were compared for teaching severely retarded boys to discriminate the position of a 0.75-in. black square and to press the response key closest to it. Seven boys were given trial-and-error training; one learned the task. The six boys who did not learn were presented with a program of graduated stimulus changes. All but one acquired the performance, and he was under appropriate control during the program. When he reached the criterion stimuli, he reverted to a position-based response learned during trial-and-error training. Six similar subjects were presented with graduated stimulus training alone. All six learned the criterion discrimination with few or no errors. Both groups were tested for retention of the criterion performance 35 days after training was completed. Two boys who had near-perfect criterion discrimination performances showed no signs of retention after 35 days. These boys had a history of trial-and-error training.     

Cooperative learning and algebra performance of eighth grade students in United Arab Emirates

This study investigated the effect of cooperative learning on eighth grade students' performance in algebra. 54 boys and 57 girls in four middle-school mathematics classes of Grade 8 in the UAE participated. Over a 3-wk. period, two classes (57 students) were taught using a cooperative learning method, and the other two classes (54 students) were taught using the traditional lecture method. Analysis of covariance using pretest scores as a covariant showed no statistically significant increase in the algebra performance for students in the cooperative learning groups compared with the traditional groups. However, boys in the cooperative setting improved significantly on the performance test compared with boys in the traditional setting.     

Good-bye, Mr. Chips: Male Teacher Shortages and Boys’ Reading Achievement

One hundred seventy-five third- and fourth-grade boys who were identified as struggling readers participated in a 10-week intervention to determine the effect of the reading teachers’ sex on boys’ reading performance, self-perceptions as readers, and view of reading as a masculine, feminine, or gender-neutral activity. Findings indicated no main effects on reading performance, yet main effects of teacher’s sex on two sub-scales of reader self-perception emerged. Evidence of interactions showed that boys responded differentially to the intervention—they responded better to female teachers. Further analysis revealed that the boys’ responses varied as much as a response to individual male teachers as to the teacher’s sex.     

The effects of stimulant drugs on curiosity behaviors of hyperactive boys

The curiosity behaviors of 20 hyperactive boys, both on and off stimulant drugs, and in relation to 20 nonhyperactive boys, were assessed. Comparisons on object, manipulative, conceptual, perceptual, and reactive curiosity tasks indicated that stimulants reduced only the object curiosity task performance of hyperactive boys, although the level tended to remain above that of nonhyperactive boys. Also, hyperactive boys both on and off drugs tended to have lower conceptual curiosity scores than controls. Implications are discussed.     

Measurement Skills in Low-Income Elementary School Students: Exploring the Nature of Gender Differences

In this research, we examined overall performance and gender differences in measurement skills in elementary-school students from low-income families. In Study 1, accuracy and error patterns were analyzed in a large sample of fourth-graders; in Study 2 error patterns and strategy usage were examined with a smaller sample of fourth-graders. Study 1 showed no main effect of gender on students’ performance. Instead, as predicted, the direction of gender difference varied as a function of problem type: boys outperformed girls on spatial/conceptual measurement, whereas girls outperformed boys on formula-based measurement, as well as on a test of computation skills. Study 2 revealed both similarities and differences in the way boys and girls approached measurement problems. Girls appeared to have specific difficulty with spatial/conceptual problems where objects and measurement units were not pictorially presented. When recording their solutions, girls generally wrote down calculations while boys made drawings. Overall, the students performed poorly in measurement; strategy analysis allowed for examination of common weaknesses, indicating possible ways of improving performance of underserved groups.     

Salience and temporal sequencing of time-related actions in boys with attention deficit/hyperactivity disorder.

Twenty-four 8- to 12-year-old boys with ADHD and 24 non-ADHD boys matched on age and IQ viewed an edited, nondialogue portion of a humorous television program to examine performance on a task requiring attention to and recall of temporal information. Participants were required to retell the story as closely as possible, to complete a picture-prompted sequencing task taken from the story, and to identify time-saving actions taken by the central character. Measures were also obtained of the number of prospective, retrospective, or present time-related references made and whether participants correctly identified the overarching time theme of the story. Significant group differences in favor of the comparison boys were evident in the total number of actions recalled and the number of events recalled in sequence. When controlling for poorer memory performance in boys with ADHD, however, there was no significant main effect of diagnostic group. A logistic regression analysis controlled for poorer memory performance indicated no significant differences between the number of boys with and without ADHD who correctly identified the overarching time theme of the story.     

Sex differences in math performance: The role of children's approach to schoolwork

This research examined whether the tendency for girls to outperform boys in the classroom is due to differences in how girls and boys approach schoolwork. In 5th grade and then again in 7th grade, children (N=518) reported on how they approach schoolwork (i.e., achievement goals and classroom behavior), their learning strategies, and their self-efficacy in math; math grades and achievement test scores were also collected. Girls were more likely than boys to hold mastery over performance goals and to refrain from disruptive classroom behavior, which predicted girls' greater effortful learning over time. The sex difference in learning strategies accounted for girls' edge over boys in terms of grades. Girls did not do better on achievement tests, possibly because self-efficacy, for which there was also no sex difference, was the central predictor of performance on achievement tests.     

School adjustment in adolescence for previously rejected,average and popular children

Background: Earlier research shows that peer‐rejected children are at risk of a wide range of subsequent adjustment difficulties in different social contexts, as, for example, in school. Aims: This study investigated the academic performance and school adjustment in adolescence of children with different peer status in middle childhood. Sample: Age 15 boys and girls (N=90), who at age 10 and 11 were sociometrically rejected, popular, or of average popularity in their school class. Methods: School marks, intelligence scales, and self‐reports were used as adjustment measures. School dropout rate for boys was also included. Results: The academic performance and intelligence level of rejected boys and girls were short of the standards of children from the other status groups, while the scores of popular boys and girls were of superior standard. There were some slight indications that rejected girls (but not rejected boys) had negative attitudes towards school and schoolwork, and that popular girls had positive school attitudes. The school dropout rate of rejected boys was much higher than that of other boys. Conclusions: The results show that the rejected children are a risk group for school problems also over a long period of time. Considering the important developmental aspects of the adolescence years, there appear to be good reasons, therefore, to worry about the future adulthood adjustment of peer‐rejected children.     

Gender Differences and Cognitive Correlates of Mathematical Skills in School-Aged Children

Published information concerning the influence of gender on mathematical ability tests has been controversial. The present study examines the performance of school-aged boys and girls from two age groups on several mathematical tasks and analyzes the predictive value of a verbal fluency test and a spatial test on those mathematical tasks. More specifically, our research attempts to answer the following two questions: (1) Are gender differences in mathematical test performance among children interrelated with age and (2) do verbal and spatial nonmathematical tests mediate gender effects on mathematical test performance? Two hundred and seventy-eight 7- to 10-year-old children and 248 13- to 16-year-olds were selected from schools in Colombia and Mexico (231 boys and 295 girls). The age effect was found to be significant for all measures, with scores improving with age. Results showed that boys and girls in both age groups scored similarly in most subtests, but that differences emerged in the performance of mental mathematical operations and in resolving arithmetical problems. In the latter – but not in mental math – older boys outperformed older girls, whereas no gender differences were observed in the younger groups. After controlling for age, it was found that the spatial test was, indeed, a significant mediator of gender effects, while the verbal task was not.     

A regression tree of the aptitudes,personality, and academic performance relationship

This study suggests regression trees as a complementary tool to regression and SEM to respond to questions related with the influence of intelligence, personality, and their interplay on academic performance. Data from 818 secondary education students (402 girls and 416 boys) in aptitudes, personality, and academic performance in four learning areas: language (Catalan and Spanish) and science (Natural and Mathematics) were modelled with this technique. Two hypotheses articulated the presentation of this methodology. Aptitudes were much more relevant than personality to explain variance in academic performance. Verbal aptitude was particularly more relevant for girls than for boys.     

Somatic Markers and Response Reversal: Is There Orbitofrontal Cortex Dysfunction in Boys with Psychopathic Tendencies?

This study investigated the performance of boys with psychopathic tendencies and comparison boys, aged 9 to 17 years, on two tasks believed to be sensitive to amygdala and orbitofrontal cortex functioning. Fifty-one boys were divided into two groups according to the Psychopathy Screening Device (PSD, P. J. Frick & R. D. Hare, in press) and presented with two tasks. The tasks were the gambling task (A. Bechara, A. R. Damasio, H. Damasio, & S. W. Anderson, 1994) and the Intradimensional/Extradimensional (ID/ED) shift task (R. Dias, T. W. Robbins, & A. C. Roberts, 1996). The boys with psychopathic tendencies showed impaired performance on the gambling task. However, there were no group differences on the ID/ED task either for response reversal or extradimensional set shifting. The implications of these results for models of psychopathy are discussed.     

The type A behavior pattern in children: relationships with performance on speed oriented tasks

The Matthews Youth Test for Health (MYTH) was completed by teachers to evaluate 85 fifth- and sixth-grade boys. Type A and B groups of 20 boys each were selected based on MYTH scores. Each boy performed a signalled reaction time task and a perceptual search task. No performance difference was found between the Type A and B boys on the reaction time task. On the perceptual search task, each boy had to scan a set of pictures and report the number of "Snoopy's" seen in each picture. A group difference in response time was found, with the Type A boys having a mean of 5.98 s versus 7.87 for the Type B boys.     

Effects of experimenter and mother presence on the attentional performance and activity of hyperactive boys

The attentional performance, activity, and off-task behavior of hyperactive boys with and without conduct problems and normal boys were compared on a cancellation task under three conditions: when performing the task alone, with mother present, and with experimenter present. Results indicated that both the hyperactive groups achieved poorer attentional scores than normal subjects in the alone and mother present conditions, but improved in the experimenter present condition. The performance of the hyperactive boys with conduct problems was particularly affected by this condition. The activity and off-task behavior scores of both the hyperactive groups were higher than controls in all conditions, although the hyperactive boys with conduct problems decreased in off-task behavior when the experimenter was present. Attention and behavior scores were not significantly correlated. The implications of these findings for assessment of hyperactivity, and the role of noncompliance in the attentional behavior of hyperactive children, are discussed.This study is based in part on the first author's Ph.D. thesis in the Department of Psychology, University of Melbourne.     

A causal model of mathematics performance in early adolescence: the role of sex

Using path analysis, the present investigation was done to clarify possible causal linkages among general scholastic aptitude, academic achievement in mathematics, self-concept of ability, and performance on a mathematics examination. Subjects were 122 eighth-grade students who completed a mathematics examination as well as a measure of self-concept of ability. Aptitude and achievement measures were obtained from school records. Analysis showed sex differences in prediction of performance on the mathematics examination. For boys, this performance could be predicted from scholastic aptitude and previous achievement in mathematics. For girls, performance only could be predicted from previous achievement in mathematics. These results indicate that the direction, strength, and magnitude of relations among these variables differed for boys and girls, while mean levels of performance did not.     

Gender bias in mothers' expectations about infant crawling

Although boys outshine girls in a range of motor skills, there are no reported gender differences in motor performance during infancy. This study examined gender bias in mothers' expectations about their infants' motor development. Mothers of 11-month-old infants estimated their babies' crawling ability, crawling attempts, and motor decisions in a novel locomotor task-crawling down steep and shallow slopes. Mothers of girls underestimated their performance and mothers of boys overestimated their performance. Mothers' gender bias had no basis in fact. When we tested the infants in the same slope task moments after mothers' provided their ratings, girls and boys showed identical levels of motor performance.     

Adolescents' expectancies of success,self-evaluations,and attributions about performance on spatial and verbal tasks

The present study examined the expectancies of success, evaluations of performance, and achievement-related attributions that high school students made about verbal and spatial tasks that typically show sex differences. Although no sex differences were found in task performance, boys expected to do better than girls on both the spatial and verbal tasks. After completing the task, the girls continued to evaluate their performance more negatively than did boys on the spatial tasks. On spatial tasks girls also attributed to themselves less ability and saw the tasks as being more difficult than did boys. The results suggest that there are generalized, rather than task-specific, sex differences in achievement expectancies, evaluations, and attributions. These findings are discussed in terms of their implications for sex-related differences in cognitive functioning and subsequent achievement behaviors.The authors gratefully acknowledge support from the Judith Offer Fund and from the Spencer Foundation.
