Motor and cognitive proficiency of learning disabled and normal children

Motor and cognitive skills of learning disabled (N = 32) and normal (N = 32) boys were compared on the Modified Lincoln-Oseretsky Motor Development Scale and on the WISC-R Vocabulary and Block Design subtests. Eight learning disabled and eight normal boys were tested at four age levels from 8 to 11 years. All boys were of normal intelligence. Motor and cognitive skills of the learning disabled boys were significantly below those of the normal boys and below those of the normative group. Chronological age was not a significant factor in relationship to either motor or cognitive skills. Intercorrelations indicated that in the learning disabled group Block Design, but not Vocabulary, was significantly related to motor scores at the 8- and 9-year ages. These results suggest that a common factor relating to perceptual-motor coordination and efficiency may be involved on the Lincoln-Oseretsky and Block Design subtest for young learning disabled children but not for older learning disabled children or for normal children.     

The impact of informant gender on children’s endorsement of scientific and non-scientific information

By roughly 6 years of age, children acquire the stereotype that men are more competent than women in science, technology, engineering, and mathematics (STEM), potentially leading to greater trust in scientific information provided by men. This study tested whether 3- to 8-year-old children differentially endorsed conflicting information about science and toys presented by male and female informants depicted as a ‘man’ and ‘woman’ (Exp1) or ‘scientists’ (Exp2). Children were expected to endorse toy testimony from gender-matched informants; thus, the key question concerned endorsement of science testimony. In Exp1 (N = 149), boys and girls showed a same-gender informant preference for toy testimony; however, girls endorsed the male informant's testimony more for science than for toys – but only when tested by a male experimenter. In Exp2 (N = 264), boys and girls showed a same-gender preference, irrespective of content. Findings suggest that STEM-related gender stereotypes might lead girls to trust scientific information presented by men over women in certain contexts.     

Sex differences on televised toy commercials

Televised toy commercials were observed during the 1977 (N=44) and 1978 (N=47) Christmas holiday seasons; children shown in the commercials were classified by sex and activity or passivity. In 1977 53 boys and 37 girls were observed; 71 boys and 35 girls were shown in 1978. There were significantly more boys than girls in the 1978 sample of commercials; more commercials contained boys than girls, and there were more boys than girls per commercial. Girls were more likely to appear in a passive role than boys were in the 1977 commercials. There were significantly fewer mixed-sex commericals than expected in 1977, but not in 1978. Percentages of commercials representing 12 toy categories and percentages of boys and girls appearing within each category are described; differences between years are discussed.     

The Borderline Personality Features Scale for Children (BPFS-C): Factor Structure and Measurement Invariance across Time and Sex in a Community-Based Sample

The factor structure and measurement invariance of the Borderline Personality Features Scale for Children (BPFS-C; Crick et al. 2005) was examined in a community-based sample of Canadian adolescents (N?=?252 boys; N?=?314 girls) assessed yearly from age 13 to age 16. Attempts to confirm the originally proposed four factor structure of the BPFS-C were not successful. Follow-up exploratory and confirmatory factor analyses provided evidence for an eleven-item, two-factor latent structure of the BPFS-C, consisting of an intra- and interpersonal preoccupation factor and an impulsivity/reactivity factor. Measurement invariance modeling provided evidence for the longitudinal invariance of the two-factor structure and suggested it possessed largely the same empirical meaning for boys and girls at each time point. Examination of latent means in the context of measurement invariance suggested that the BPFS-C two factor structure was: (1) relatively stable across mid-adolescence; and (2) relative to boys, girls showed elevations on the intra-and interpersonal preoccupation factor, providing further evidence for ‘true’ sex differences in rates of borderline personality features. The importance of measurement science for providing a solid, empirically-based foundation for developmental research on the emergence of borderline personality features in children and adolescence is discussed.     

Social Interaction During Computer-based Activities: Comparisons by Number of Sessions, Gender, School-level, Gender Composition of the Group, and Computer-child Ratio

This study assessed the quality of social interactions that occur in group-based computer learning contexts. Gender comparisons of interactions were examined across 3 sessions with 116 preschoolers (M age?=?4.9 years) and 108 fifth and sixth-grade (M age?=?11.7 years) Canadian children from southwestern Ontario, when children had access to one computer per child (parallel computer) or one computer per group (integrated computer), and when they worked with same-gender or mixed-gender peers. Preschoolers engaged in more collaborative behaviors in mixed-gender than same-gender groups, while elementary children engaged in collaborative behaviors more often in integrated than parallel computer conditions. In mixed-gender groups, boys were more likely than girls to dominate the computer in elementary school while girls were more likely than boys to dominate the computer in preschool.     

Pink gives girls permission: Exploring the roles of explicit gender labels and gender-typed colors on preschool children's toy preferences

Children engage in gender-typed toy play to a greater extent than in non-gender-typed toy play leading to different developmental trajectories for boys and girls. The present studies examine the characteristics of toys and how they differentially affect boys' and girls' interests, stereotypes, and judgments of the toys. In Study 1, children (N = 73, M_age = 4.01) were presented with masculine and feminine toys that were decorated with masculine and feminine colors. Results indicated that boys were more interested in masculine toys than in feminine toys. Girls were significantly less interested in masculine toys with masculine colors than in all other combinations. Children's perceptions of others' interests also followed a similar pattern. In Study 2, children (N = 42, M_age = 3.84) were presented with novel items labeled as “for boys” and “for girls” and decorated in masculine and feminine colors. Among girls, both explicit labels and color of novel toys impacted interests. Children's predictions of others' interests also reflected this pattern.     

Gender differences on the WPPSI, the WISC-R, and the WPPSI-R

The WPPSI, WISC-R, and WPPSI-R were administered in a counterbalanced design to 72 children between the ages of 5 years, 10 months, 16 days, and 6 years, 7 months, and 15 days to test the hypothesis that mean verbal IQs on these scales would be higher for boys than for girls. Results indicated that the mean verbal IQs for boys were significantly (p<.05) higher than those for girls on all three scales. Also, significant (p<.05) differences favoring boys were found onVocabulary andComprehension subtests on all three scales. These differences are probably a peculiarity of these scales and may not need any elaborate theoretical explanation. However, clinical uses of verbal and performance IQ discrepancies may not justifiably ignore the examinees’ gender.     

Children's choices of and value judgments about sex-typed toys and occupations

Boys (N = 97) and girls (N = 96) from kindergarten through sixth grade were asked to select toys and occupations under one of the following three instructional sets: (1) choose for a girl, (2) choose for a boy, (3) choose the best one. Results indicated that children made selections for boys and girls which were in accordance with culturally accepted stereotypes. However, children's selections of the best toys and occupations were more sex-typed in the masculine direction for boys than in the feminine direction for girls. In addition, as children grew older, their choices of occupations, but not of toys, became more sex-typed. These results were discussed in terms of implications for self and career development.

Concurrent Verbal and Emotion Laterality Effects Exhibited by Normally Achieving and Learning Disabled Children

This study assessed both left- and right-hemisphere functions simultaneously when two-syllable words differing only in the initial stop consonant and spoken in different emotional tones were paired dichotically. Seventy-two right-handed normally achieving children, 12 boys and 12 girls at each of grades 1, 3, and 5, were instructed to detect either the presence of a specific word or of a specific emotion. In addition, 30 right-handed learning disabled (LD) children (age-matched to the normal controls) were assessed to determine whether LD children distribute verbal and nonverbal functions to different hemispheres. Results indicated that although both control and LD children demonstrated an overall REA for word stimuli and an LEA for emotional stimuli, and that emotional stimuli were easier to process than word stimuli, LD children were less accurate in processing both types of stimuli than their control counterparts. ‘Complementary specialization,’ as assessed through distribution of laterality effects, was found to be greater for control children than for LD children. However, the lack of consistency in complementary specialization found among the three developmental grade levels may be indicative that independent brain mechanisms underlying verbal and emotional processing have yet to be fully established in children. Further, in contrast to adult findings, a larger LEA was obtained for the emotion ‘happy’ than for the emotion ‘sad.’ It was concluded that whereas independent hemisphere processing for words and emotions is somewhat prevalent for control children, LD children might not be as strongly lateralized for opposite hemisphere processing of these functions.     

The effects of verbal feedback and listener type on the speech of preschool children

The present study simultaneously assessed the relative contributions of feedback indicative of comprehension and the apparent age of the listener, either an adult or a doll which resembled a toddler, in a 2 (listeners) × 2 (types of feedback, C = comprehension, NC = noncomprehension) design. Two groups of children, a 3-year-old (N = 13, 7 boys, 6 girls) and a 5-year-old group (N = 12, 6 boys, 6 girls) were asked to tell stories to both the adult and doll in both C and NC conditions. The doll was constructed with an internal speaker such that it could actually carry on a conversation with the children. The conversations were taped, transcribed, and scored for mean length of utterance (MLU), transitional utterance length to each C and NC signal, and the proportion of child questions, exact self-repetitions, repetition and reductions, and rephrases/elaborations. The data analysis revealed that all children appropriately modified the length of their utterances (MLU) in the doll condition but not in the adult condition, indicating that they were sensitive to both the feedback and the nature of their listeners. Older children were more likely than younger children, and girls more likely than boys to adjust the length of their utterances appropriately to each type of feedback, slightly increasing the length of the subsequent utterance to a C signal and decreasing the length to an NC signal. The younger children were also more likely to respond with a simple repetition to NC cues from the adult.     

Global self-esteem,perceived athletic competence,and physical activity in children: A longitudinal cohort study

ObjectivesThe Exercise and Self-Esteem Model is used as a theoretical framework to describe associations between global self-esteem and physical activity, mediated by perceived athletic competence. We know little about how these associations develop over time in elementary school children. We examined the change in, and associations between, global self-esteem, perceived athletic competence, and moderate-to-vigorous physical activity (MVPA) in children from kindergarten to grade 4. We also investigated if this change and these associations were different for boys and girls.DesignA prospective longitudinal cohort-sequential design that consisted of two cohorts of children.MethodChildren in cohort I were followed from kindergarten to grade 2, and children in cohort II were followed from grade 2 to grade 4. Global self-esteem and perceived athletic competence were measured with the Self-Perception Profile for Children (SPPC) (n = 292; 148 boys), while MVPA was measured with proxy-reports for physical activity filled in by parents (n = 184; 88 boys).ResultsGlobal self-esteem, perceived athletic competence, and MVPA remained stable. Global self-esteem was the same in boys and girls, while boys reported higher levels of perceived athletic competence and were more physically active than girls. The change in global self-esteem was significantly associated with perceived athletic competence and MVPA in girls, but not in boys.ConclusionThere are few developmental changes in global self-esteem, perceived athletic competence, and MVPA from kindergarten to grade 4. The change in global self-esteem was associated with perceived athletic competence and MVPA in girls, but not in boys.     

Perceptions of teacher’s feedback and learning environment as predictors of intrinsic motivation in physical education

Objectives: To investigate whether the perceptions of different domains of the learning environment in physical education, such as perceived teacher feedback, perceived challenge, perceived competitiveness and perceived threat to sense of self, are related to intrinsic motivation.Method: School children (N=783; n=375 boys, n=408 girls) aged 12–15 yrs completed three questionnaires. The physical education learning environment scale (PELES) was used to investigate the perceived threat to sense of self, perceived challenge and perceived competitiveness. The perceptions of the teacher’s feedback (PTF) questionnaire was developed for this study. The construct validity of factor structure of the instrument was confirmed by confirmatory factor analysis (CFA). Students’ intrinsic motivation was assessed by the intrinsic motivation inventory (IMI).Results: For middle school students, the most important predictors of intrinsic motivation were the perceived threat to sense of self, perceived challenge and perceived positive general feedback. Exploratory factor analyses (EFA) and CFA provided evidence of the adequate construct validity for the PTF and confirmed the construct validity for the PELES.Conclusion: Teachers need to create a learning environment that leads students to perceive it as non-threatening and challenging. They should seek to provide positive general feedback to create a more stimulating learning environment.     

Development of learning-disabled and normally achieving children's causal attributions

The causal attributions of learning-disabled (LD) and normally achieving (NA) children in grades 3 through 8 were compared. Attributions were measured by two scales that asked children to attribute hypothetical academic failure situations to factors that were either within (e.g., insufficient effort) or beyond (e.g., insufficient ability, blaming others) their control. Consistent with a learned helplessness hypothesis, LD girls, regardless of age, were more likely than NA children to attribute their failures to factors beyond their control. In contrast, LD boys' explanations for their failures paralleled those of NA children. That is, with increasing age the LD boys were more likely to attribute their failures to insufficient effort. Explanations and implications of sex differences in developmental patterns of LD children's causal attributions are discussed.The authors wish to thank Ruth Dusseault and Betty Wallace for their help in conducting this research. We also wish to thank the teachers, children, and administrators from the Leon County Schools for their cooperation.     

Children’s Gender-Typed Activity Choices Across Preschool Social Contexts

Variability in children’s gender-typed activity preferences was examined across several preschool social contexts--solitary play, interactions with female peers, male peers, and both, and interactions with teachers. Participants were preschool children (N?=?264; 49?% girls, M age?=?52?months, range 37–60) attending Head Start classes in the Southwest United States. Seventy-three percent were Mexican/Mexican-American, and 82?% of families earned less than $30,000 per year. Children’s preferences for gender-typed activities varied as a function of their own gender and the identity of their interactional partners. Girls and boys preferred gender-typed activities (e.g., girls preferred feminine activities) when in solitary play but activity preferences changed across social contexts. Specifically, girls played significantly more with masculine activities when with male peers and boys played significantly more with feminine activities during interactions with teachers. Findings suggest that through social interactions with peers and teachers, children are exposed to a greater range of activities than what they experience when they play by themselves.     

Building a Pink Dinosaur: the Effects of Gendered Construction Toys on Girls’ and Boys’ Play

Play with building toys such as LEGO® sets promotes spatial learning in children. The present study examined the effects of the color of the bricks (either pink or blue) and the femininity/masculinity of the object built on boys’ and girls’ play with LEGO® sets. Children (n = 116, M _age  = 7.27 range = 5–10) were given the opportunity to build with LEGO® brick sets, both instructed and free play tasks. For the instructed task, the type of object (feminine: cat; masculine: dinosaur) and color of the bricks (pink, blue) were counterbalanced across participants. Their play was coded for accuracy of following the instructions and time to complete the task. In the free play task, brick color (pink, blue) was counterbalanced across participants, and structures were coded for femininity/masculinity and the number of bricks used. Overall, children took longer to build a feminine object with blue bricks than with pink bricks. In the free-play task, boys built more masculine objects than girls did, regardless of the color of bricks they were given. Results showed that boys completed the LEGO® tasks faster than did girls, controlling for interest in and experience with LEGO® play. These findings suggest that toy color and type can impact how children interact and play with toys.     

Gender and developmental differences in children's conversations

Extending work on childhood gender differences by J. Block (“Assimilation, Accommodation and the Dynamics of Personality Development,” Child Development, 1982, 53, 281–295) and J. H. Block (“Differential Premises Arising from Differential Socialization of the Sexes: Some Conjunctures,” Child Development, 1983, 54, 1335–1354), the present research investigated assimilative and accommodative discourse devices in the speech of 24 preschool children (12 boys and 12 girls) and 24 middle-childhood youngsters (12 boys and 12 girls) in each of grades 3 and 6. Boys' discourse, regardless of age, contained more accommodative devices. Girls' discourse, regardless of age, contained more assimilative devices. Age effects were apparent; older children, regardless of gender, used more discourse devices of both kinds than younger children.     

The Peer Interaction in Primary School Questionnaire: testing for measurement equivalence and latent mean differences in bullying between gender in Egypt,Saudi Arabia and the USA

The Peer Interaction in Primary School Questionnaire (PIPSQ) was developed to assess individuals’ levels of bullying and victimization. This study used the approach of latent means analysis (LMA) within the framework of structural equation modeling (SEM) to explore the factor structure and gender differences associated with the PIPSQ in a sample of Egyptian (N = 361), Saudi Arabian (N = 350) and USA (270) children. Results of the confirmatory factor analysis are consistent with previous work and support the cross-cultural validity of the PIPSQ factor structure. The PIPSQ factor loadings were invariant across Egyptian and Saudi samples, whereas only partial invariance was met between Egyptian or Saudi samples and the USA sample. Full measurement invariance was met between gender within the three cultures, that is the PIPSQ was useful to compare bullying and victims between gender within the three cultures, but it is only valid to compare those two constructs between Egyptian and Saudi boys and girls. The results indicated that Egyptian and Saudi boys/girls had a higher level of bullying than American boys/girls, whereas no differences were displayed among the three cultures on the victimization subscale. Boys had a higher level of bullying than girls in the three cultures, and boys and girls had a similar level of victimization in three cultures.     

Variations in birth weight within the normal range are related to visual orienting in infancy for boys but not for girls

Pooling across 27 experiments on visual orienting during early infancy generated a large sample of full-term infants with birth weights greater than 2500 g (N=944). A weight-for-date measure was obtained separately for girls and for boys by residualizing birth weight on gestational age at birth. The proportion of trials with orienting toward a moving target increased directly with this weight-for-date measure for boys but not for girls in a linear regression with adjustments for gestational age at testing, birth order and visual stimulus parameters across experiments. The same relations held when raw birth weight was used as a predictor. For the 475 boys, the z-score of the orienting measure increased by 0.221 for each kilogram increase in birth weight corrected for gestational age (0.196 z-units per kilogram adjusted for covariates, 95% CI = 0.04–0.35 z-units per kg, P=0.014). The interaction of gender and birth weight in this association makes explanations based on confounding family social variables less tenable as explanations. This association primarily for boys is similar to recently reported associations between birth weight and IQ during childhood. Possible factors underlying this association such as prenatal nutrition are discussed.     

Effect of Child Gender on the Bidirectional Relationships between Parental Monitoring and Delinquent Behavior

This study examined the effect of child gender on the bidirectional relationships between perceived parental monitoring and self-reported delinquent behaviors from childhood to adolescence, using data from the Korean Youth Panel Study. In this longitudinal study, different age cohorts for childhood (ages 9–12; N?=?2283) and adolescence (ages 13–16; N?=?2722) were analyzed. The findings from cross-lagged path analyses showed that the parent–child relationships differed for boys and girls. For girls, delinquency had a stronger effect on parental monitoring in childhood, whereas parental monitoring had a stronger effect on delinquency in the childhood–adolescence transition and adolescence. Boy’s delinquency similarly had a stronger effect in childhood. Parental monitoring, however, did not affect boy’s delinquency at any age. This study highlights the importance of considering gender when developing interventions to support families with delinquent children and adolescents.
