Reviews involving the Wechsler Scales for children suggest that Full Scale IQ scores on the Wechsler Intelligence Scale for Children, Third Edition, average 5 to 6 points lower than scores on the second edition of the scale [WISC‐R, Wechsler, D. (1974). Zimmerman & Woo‐Sam, 1997], with the differences distributed disproportionately over subtests, i.e., with larger discrepancies found within the Performance Scale (Wechsler, 1991). Changes on the revised subtests of the WISC‐III Performance Scale may place children with ADHD at a disadvantage compared to their performance on analogous WISC‐R subtests. We examined IQ test performance in 122 unmedicated children with ADHD (61 given the WISC‐R, 61 given the WISC‐III), and 46 children from a healthy, comparison group (23 given the WISC‐R, 23 given the WISC‐III). The ADHD and comparison group samples were matched for sex and for Verbal IQ between WISC‐R and WISC‐III. Children with ADHD had significantly lower Performance IQ on WISC‐III compared to the WISC‐R, with the Picture Arrangement subtest showing the most significant difference. In contrast, there were no significant differences between the WISC‐R and WISC‐III cohorts on Performance IQ or any Performance subtests among the comparison group. These findings highlight the importance of examining the comparability of ability test revisions among clinical and non‐clinical populations, and will be especially salient when the WISC‐III is revised. © 2003 Wiley Periodicals, Inc.

The present study focuses on math and related skills among 32 girls with fragile X (n = 14) or Turner (n = 18) syndrome during late elementary school. Performance in each syndrome group was assessed relative to Full Scale IQ-matched comparison groups of girls from the general population (n = 32 and n = 89 for fragile X syndrome and Turner syndrome, respectively). Differences between girls with fragile X and their comparison group emerged on untimed arithmetic calculations, mastery of counting skills, and arithmetic problem verification accuracy. Relative to girls in the comparison group, girls with Turner syndrome did not differ on untimed arithmetic calculations or problem verification accuracy, but they had limited mastery of counting skills and longer response times to complete the problem verification task. Girls with fragile X or Turner syndrome also differed from their respective comparison groups on math-related abilities, including visual-spatial, working memory, and reading skills, and the associations between math and those related skills. Together, these findings support the notion that difficulty with math and related skills among girls with fragile X or Turner syndrome continues into late elementary school and that the profile of math and related skill difficulty distinguishes the two syndrome groups from each other.  相似文献

We examined the information processing capabilities of children diagnosed with the inattentive subtype of attention-deficit/hyperactivity disorder (ADHD) who had been characterized as having a sluggish cognitive tempo. Children referred for school-related problems (n = 81) and nonreferred community controls (n = 149) participated. Of the referred children, 24 met criteria for ADHD, 42 met criteria for reading disability (RD), and 9 of these were comorbid for RD and ADHD. Children with ADHD differed from those without ADHD on a visual search task but not on an auditory processing task; the reverse was true for children with RD. Decomposition of the visual search task into component operations demonstrated that children in the ADHD group had a slow processing rate that was not attributable to inattention. The children with ADHD were not globally poor at information processing or inattentive, but they demonstrated diminished speed of visual processing.  相似文献

Developmental changes in the resolution of conflicting goals involved in self-evaluation were examined in children entering second, fourth, and sixth grades representing high, medium, and low ability levels in arithmetic. Children completed a series of arithmetic tasks and were given an opportunity to evaluate themselves in terms of social comparison or autonomous comparison. As expected, overall, high-ability children engaged in the most self-evaluative information seeking, whereas low-ability children engaged in the least information seeking. Moreover, with increasing age, high-ability children were more likely to engage in autonomous comparison, whereas low- and medium-ability children maintained an interest in social comparison. In addition, greater interest in social comparison, particularly among older children, was associated with relative uncertainty about one's own ability but perceptions of ability as constant in others. The results are discussed in terms of strategies for balancing self-assessment with self-enhancement needs and the impact of such strategies for task mastery.  相似文献

The behavioral, self-evaluative, and attributional responses of 120 boys with Attention-Deficit/Hyperactivity Disorder (ADHD) and 65 control boys to social success and failure were examined using a dyadic, laboratory get-acquainted task employing child confederates. Objective coders rated boys with ADHD as less socially effective than controls in their interactions, but also as less frustrated and helpless. In terms of self-evaluations, ADHD boys overwhelmingly rated their own performance more favorably than did controls and in some instances, these differences were more apparent following failure. The attributional pattern of ADHD and control boys differed in that ADHD boys were more likely than controls to attribute success to external, uncontrollable factors such as task ease and being lucky; controls, on the other hand, were more likely than ADHD boys to attribute initial failure to not having tried hard enough. Results are discussed in the context of existing literature documenting a positive illusory bias in ADHD boys' self-perceptions.  相似文献

This study compared private speech of children with ADHD and normal controls during problem solving and inhibition tasks. Thirty-two children (16 children with ADHD and 16 matched controls) aged 6–11 years participated. Consistent with previous studies, children with ADHD produced more task-irrelevant and task-relevant external private speech than control children during problem-solving tasks, but did not differ in their use of task-relevant internal private speech. During the inhibition/attention task (Continuous Performance Test-II), children with ADHD produced more task-relevant external and more task-relevant internal private speech, suggesting that they may have employed a less mature strategy to aid in self-regulation. The educational implications of the current study are that there should be an increased awareness of the developmental nature and functional significance of private speech and how private speech usage may differ in children with ADHD.  相似文献

Research findings regarding the relationship of social skills deficits and behavioral characteristics associated with attention-deficit hyperactivity disorder (ADHD) among kindergarten-age children are presented. The Preschool and Kindergarten Behavior Scales (PKBS) were utilized to identify the social skills attributes of young children with significant ADHD characteristics. An ADHD target group (N = 95) was constructed by selecting participants from a large nationwide sample who were rated by their teachers as being in the highest 5% on the PKBS Attention Problems/Overactive subscale. A matched non-ADHD comparison group (by gender and age) of 95 children was developed through a randomized block procedure using the same nationwide sample. The ADHD group was rated as having significantly poorer social skills than the comparison group, and could be classified with a very high degree of accuracy based on discriminant function analysis of their social skills scores. Although exhibiting comparative deficits in all social skill areas, the ADHD participants were especially lacking in social cooperation skills: the ability to follow rules, structure, and important social expectations of both children and adults. Children who were rated high in ADHD characteristics were between five and six times more likely than the comparison children to be rated as having significant deficits in social skills. Implications of these findings for assessment and treatment of young children are discussed. © 1998 John Wiley & Sons, Inc.  相似文献

Abstract

Twenty-two boys with a diagnosis of ADHD were com-KEYWORDS pared with 22 typically developing boys on an advanced theory of mind task and on two tasks measuring aspects of executive function. Parents completed rating forms measuring general social competence, as well as mentalizing and non-mentalizing social behaviours. There were no differences between the groups on the advanced theory of mind measure.The children with ADHD scored more poorly than controls on an inhibition task but not on a planning task once age and IQ had been covaried. Ratings of social competence were correlated with theory of mind and executive function ability for the typically developing controls but not for the children with ADHD. The results are discussed in terms of inhibitory and social information processing accounts of ADHD.  相似文献

Children with mild intellectual disabilities (MID) appear to have particular problems in understanding the numerical meaning of Arabic digits. Therefore, we developed and evaluated a numerical domino game that specifically targeted the association between these digits and the numerical magnitudes they represent. Participants were 30 children with MID (M = 8.36 years), randomly assigned to either the numerical domino game or to a control color domino game. Findings revealed that both groups of children improved on a nonsymbolic comparison and arithmetic task. Most importantly, only children who played the numerical domino game became significantly faster from pretest to posttest on a symbolic comparison task. These findings suggest that numerical magnitude processing can be successfully trained in children with MID.  相似文献

The accuracy and time required for children with and without learning disabilities to interpret emotions when restricted to information from facial expressions, and the accuracy of those interpretations, were investigated. Ninety-six children participated; an equal number of males and females were included in both learning categories and age levels. Accuracy and response time on a modified version of Pictures of Facial Affect were recorded for the emotions of fear, sadness, surprise, anger, happiness, and disgust, as well as for the entire task. Three-way ANOVAs revealed children with learning disabilities to (a) be less accurate interpreters of emotion and (b) spend more time identifying specific emotions. Both age and sex influenced response time: Younger subjects required more time to interpret the emotions of fear and anger; males spent more time interpreting happiness. Younger females with learning disabilities displayed difficulty in interpretation, and older children with learning disabilities (particularly males) were rapid, but often inaccurate, interpreters of emotion.  相似文献

Perceived and actual academic competence in maltreated children   总被引：2，自引：0，他引：2  
OBJECTIVE: The aims were twofold: 1) to determine whether maltreated and nonmaltreated children differed in the accuracy of their self-assessments of academic achievement; and 2) to determine whether discrepancies between perceived and actual academic competence were related to perceptions of social support from mothers, teachers, and peers. METHOD: A sample of 195 maltreated children known to a state protective service agency was compared to a control group of 179 nonmaltreated children. The groups were matched on child's gender, age, ethnicity, and birth order; socioeconomic ranking of neighborhood; and family structure. RESULTS: Although maltreated children had significantly lower achievement scores than did nonmal-treated children, the two groups did not differ on perceived academic competence. With regard to discrepancies between perceived and actual competence, maltreated children were more likely than nonmaltreated children to overestimate their level of competence, particularly for reading and arithmetic. Overall, children who reported low maternal support were more likely to overestimate reading competence than were those who reported average or high maternal support. When maltreatment status was considered, maltreated children with low support seemed likely to overestimate abilities, whereas nonmaltreated children with low support seemed likely to underestimate competence. CONCLUSIONS: Maltreated children may overestimate their academic abilities in order to compensate for self-perceptions of low self-worth. Efforts to improve academic performance in maltreated children should focus not only on increasing academic skills but also on enhancing self-esteem.  相似文献

Children’s problem solving while working by themselves or with a partner was investigated to explore whether young children are susceptible to social facilitation and social loafing. Five‐year‐olds were asked to complete easy or hard puzzles, either alone or with a partner. Half of the children were given instructions indicating that their performance would be evaluated and the other half were not. Children showed social facilitation, in that they performed better with a partner than when working alone under evaluation conditions, with the easy puzzle. Children also showed social loafing, in that performance with a partner was poorer when working under no evaluation than evaluation conditions, with the easy puzzle. Performance with the hard puzzle did not differ whether children worked alone or with a partner, but children working on the hard puzzle under no evaluation conditions performed better than those working under evaluation conditions. The findings suggest that evaluation affects children’s performance in group settings in different ways depending on task difficulty.  相似文献

Although many children with reading difficulty (RD) are reported to struggle with mathematics, little research has empirically investigated whether this is the case for different types of RD. This study examined the mathematics skills of third graders with one of two types of RD: dyslexia (n = 18) or specific reading comprehension difficulty (n = 22), as contrasted to a comparison group (n = 247). Children's performance on arithmetic fact fluency, operations, and applied problems was assessed using standardized measures. The results indicated that children with dyslexia experienced particular difficulty with arithmetic fact fluency and operations: they were 5.60 times and 8.54 times more likely than other children to experience deficits in fact fluency and operations, respectively. Our findings related to arithmetic fact fluency were more consistent with domain-general explanations of the co-morbidity between RD and mathematics difficulty, whereas our findings related to operations were more consistent with domain-specific accounts.  相似文献

Using a multimodal and multi-informant method for diagnosis, we selected 33 children by teacher and parent nomination for attention and work completion problems that met DSM-IV criteria for attention-deficit/hyperactivity disorder (ADHD). Of the 33 children in this group, 21 participated in the initial intervention, and 12 were placed in an ADHD control group and received the intervention after pre- and posttesting. A similarly selected group of 21 children without difficulties in attention and work completion served as a control group. Each child was assessed on pre- and posttest measures of visual and auditory attention. After an 18-week intervention period that included attention and problem-solving training, all children in the intervention and control groups were retested on visual and auditory tasks. Children in both ADHD groups showed significantly poorer initial performance on the visual attention task. Whereas the ADHD intervention group showed commensurate performance to the nondisabled control group after training, the ADHD control group did not show significant improvement over the same period. Auditory attention was poorer compared to the control group for both ADHD groups initially and improved only for the ADHD intervention group. These findings are discussed as a possible intervention for children with difficulties in strategy selection in a classroom setting.  相似文献

Reversal errors play a prominent role in theories of reading disability. We examined reversal errors in the writing of letters by 5- to 6-year-old children. Of the 130 children, 92 had a history of difficulty in producing speech sounds, a risk factor for reading problems. Children were more likely to reverse letter forms that face left, such as <d> and <J>, than forms that face right, such as <b> and <C>. We propose that this asymmetry reflects statistical learning: Children implicitly learn that the right-facing pattern is more typical of Latin letters. The degree of asymmetry that a child showed was not related to the child’s reading skill at Time 2, 2¾ years later. Although children who went on to become poorer readers made more errors in the letter writing task than children who went on to become better readers, they were no more likely to make reversal errors.  相似文献

This study examined children's conception of listening and their performance as listeners, 7-, 9-, and 11-year-old children were interviewed for their conceptions of good listening, their beliefs about appropriate actions for confused listeners to take, their attributions of responsibility for a listener's confusion, their reports of how speakers and listeners feel during communication breakdown, and their ability to detect inconsistencies during a comprehension-monitoring task. Results indicated that older children relied less on behavioral orientation and more on attempts to comprehend and other criteria in their definitions of good listening. Children believed that appropriate listening responses depend on the situation, and there was a developmental increase in asking the speaker a question and listening more carefully. With age, children also tended to report more complex negative emotions for listeners and speakers experiencing a breakdown in understanding. Children recalled incongruent material more than congruent material on the comprehension-monitoring task.  相似文献

In an effort to explore the value and feasibility of teaching the principles behind developmentally appropriate practices to parents, 53 families with young children were studied. Parents were randomly assigned to participate or not participate in a three month-long, weekly, parent training program. Following completion of the program members of participating families were less likely to engage in conflict during a puzzle solving task than were members of nonparticipating families. Parents who participated were more likely to take a supportive leadership role and have age-appropriate expectations during a puzzle solving task than were nonparticipating parents. Children in participating families showed better social skills than children in nonparticipating families. Portions of the increase in social skills were related to reductions in family conflict and to the development of a task orientation that was more appropriately focused on process than outcome. Lower family conflict was also related to better gross motor skills in children.  相似文献

This study evaluated the effect of sound-symbol association training on visual and phonological memory in children with a history of dyslexia. Pretests of phonological and visual memory, a sound-symbol training procedure, and phonological and visual memory posttests were administered to children with dyslexia, to children whose dyslexia had been compensated through remedial training, and to age- and reading level-matched comparison groups. Deficits in visual and phonological memory and memory for sound-symbol associations were demonstrated in the dyslexia group. For children with dyslexia and children whose dyslexia had been remediated, the sound-symbol training scores were significantly associated with word and pseudoword reading scores and were significantly lower than those of the comparison groups. Children with dyslexia and children whose dyslexia had been compensated showed significantly less facilitation of phonological memory following the training than did typical readers. Skilled readers showed some reduction in accuracy of visual memory following the training, which may be the result of interference of verbalization with a predominantly visual task. A parallel decrease was not observed in the children with dyslexia, possibly because these children did not use the verbal cues. Children with dyslexia and children whose dyslexia had been compensated seemed to have difficulty encoding the novel sounds in memory. As a result, they derived less phonological memory advantage and less visual memory interference from the training than did typical readers. Children in the compensated dyslexia group scored lower on sound-symbol training than their age peers. In other respects, the scores of these children were equivalent to those of the typically reading comparison groups. Children in the compensated dyslexia group exhibited higher phonological rehearsal, iconic memory, and associative memory scores than children in the dyslexia group. Implications for the remediation of dyslexia are discussed.  相似文献

An Erratum has been published for this article in Psychology in the Schools 42(2) 2005, 227 [ ]. This research utilized parent report to examine the prevalence of attention deficit hyperactivity disorder (ADHD), related treatment, and associated educational outcomes among elementary school children in southeastern Virginia. In a representative sample of elementary school children, 17% had been diagnosed with ADHD. The majority of diagnosed children had been medicated for ADHD (84%). More than one third of students taking medication had received no other interventions for ADHD. Over half of the diagnosed students received behavioral therapy and almost half received a combination of medical and behavioral interventions. Children diagnosed with ADHD were 3 to 7 times ( p values < 0.001) more likely than other children to receive special education, be expelled or suspended, and repeat a grade. Based on parental opinion, children diagnosed with ADHD are at high risk for school failure. Results are discussed in terms of distinctions between clinical efficacy/effectiveness and schoolwide and public health interventions implemented in the study region. © 2002 John Wiley & Sons, Inc.  相似文献
