The Wide Range Assessment of Memory and Learning (WRAML; Sheslow & Adams, 1990) is a nationally standardized instrument designed to assess memory and learning skills in children and adolescents. This study assessed the relationship of WRAML scores to WISC-III and WJ-R results in three groups: (a) LD children with reading difficulties, (b) ADHD children, and (c) nonhandicapped referred children. Total sample size was 120. Discriminant function analysis demonstrated that the WRAML provided little distinguishing information for ADHD and LD children. Likewise, the usefulness of the Learning subtests is questionable. It is suggested that inclusion of working memory tasks that require reconfiguration of material, problem solving, and more complexity may be more beneficial in identifying processing weaknesses with suspected ADHD and LD youngsters. © 1996 John Wiley & Sons, Inc. 相似文献

Utility of the PASS theory and cognitive assessment system for Dutch children with and without ADHD 总被引：2，自引：0，他引：2
This study examined the utility of the Planning, Attention, Simultaneous, Successive (PASS) theory of intelligence as measured by the Cognitive Assessment System (CAS) for evaluation of children with attention-deficit/hyperactivity disorder (ADHD). The CAS scores of 51 Dutch children without ADHD were compared to the scores of a group of 20 Dutch children with ADHD. The scores of the Dutch children were also compared to American standardization samples of children with and without ADHD. The findings showed that children with ADHD in both countries demonstrated relatively low scores on the Planning and Attention scales of the CAS, but average scores on the Simultaneous and Successive scales. These findings are similar to previously published research suggesting that the PASS theory, as operationalized by the CAS, has sensitivity to the cognitive processing difficulties found in some children with ADHD. 相似文献

Substance use, substance abuse, and LD among adolescents with a childhood history of ADHD 总被引：5，自引：0，他引：5
A clinic-referred sample of 109 children with attention-deficit/hyperactivity disorder (ADHD) was followed into adolescence for the ascertainment of alcohol and other drug use and abuse. Learning disability (reading or math) in childhood was examined as a predictor of adolescent substance use and substance use disorder for alcohol and marijuana. No statistically significant group differences for children with LD versus those without LD emerged even after using different methods to compute LD. IQ/achievement discrepancy scores were similarly not predictive of later use or abuse. However, children with ADHD who had higher IQs and higher levels of academic achievement in childhood were more likely to try cigarettes, to smoke daily, and to have their first drink of alcohol or first cigarette at an early age. Children with ADHD who had higher reading achievement scores were less likely to have later alcohol use disorder. Although these findings are necessarily preliminary, due to the small number of children interviewed, the pattern of results suggests that level of cognitive functioning--rather than discrepancy between IQ and achievement--is important for the prediction of later substance use and abuse, at least in this clinic-referred sample of children with ADHD. Further, different mechanisms of risk related to cognitive functioning may be operating for experimentation with legal drugs such as alcohol and tobacco, regular cigarette smoking, and problematic alcohol use. 相似文献

Because of the Flynn effect, IQ scores rise as a test norm ages but drop on the introduction of a newly revised test norm. The purpose of the current study was to determine the impact of the Flynn effect on learning disability (LD) diagnoses, the most prevalent special education diagnosis in the United States. Using a longitudinal sample of 875 school children who were initially diagnosed with LD on the Wechsler Intelligence Scale for Children-Revised (WISC-R), children experienced a significant decline in IQ when retested on the third edition of the WISC (WISC-III) compared to peers who were tested on the WISC-R twice. Furthermore, results from logistic regression analyses revealed that the probability of a rediagnosis of LD on reevaluation significantly decreased, in part, because of this decline on the WISC-III. These results are discussed in terms of their implications for both basic research and educational policy. 相似文献

A few studies have shown more central auditory processing deficits in children with attention-deficit/hyperactivity disorder (ADHD) than in nondisabled children. Because these studies failed to screen participants with ADHD for learning disabilities (LD), it is not clear whether these deficits are correlates of ADHD or LD or both. In the present study, the central auditory processing ability of children with ADHD, ADHD with LD, and no disabilities was examined. Results indicated lower central auditory processing ability, and significant correlations between reading and ADHD symptoms and reading and central auditory processing ability in the ADHD with LD group compared with the other two groups. These findings suggest that central auditory processing deficits are more likely to be associated with LD than ADHD. 相似文献

This study assesses information processing and memory functioning in 50 children diagnosed with Attention Deficit Hyperactive Disorder (ADHD) with and without learning disabilities (LD). Mode of presentation (visual vs. auditory), type of memory processing (immediate, short-term, and long-term), and order of recall (ordered vs. unordered) were assessed using the Learning Efficiency Test-II (LET-II). Both groups demonstrated difficulty with auditory ordered recall and lost substantial information from immediate memory to short-term and long-term memory stores. The ADHD/LD group also demonstrated more difficulty with ordered recall than the ADHD only group. While there were no differences between the two groups in regard to immediate recall, the ADHD/LD group demonstrated more problems transferring information into short-term and long-term memory stores than the ADHD only group. Verbal interference effects significantly decreased retention for both visual and auditory processing. Results indicate that ADHD alone presents significant problems in information processing, but the comorbid effects of a learning disability further intensify the negative impact of ADHD. © 1996 John Wiley & Sons, Inc. 相似文献

This study attempted to determine whether children with the combined subtype of attention-deficit/hyperactivity disorder (ADHD) have impairments in cognitive functioning and motor skills. The specific effect of the comorbidity of learning disabilities (LD) was also investigated. A battery of cognitive tests was administered to 26 children with a clinical diagnosis of ADHD-combined subtype (ADHD/C), to 24 children with ADHD/C with a comorbid diagnosis of LD (ADHD/C+LD), and to 102 participants without disabilities, all between ages 7 and 10. The testing battery consisted of tasks assessing memory, visuospatial and verbal abilities, and fine motor skills. In general, the test results of children with ADHD/C were poorer than those of the control group but better than the results of children with a combined ADHD/C+LD diagnosis (with the exception of motor skills). The predictive accuracy of the testing battery tasks in children with ADHD/C and ADHD/C+LD was examined. The results of a standard procedure of discriminant function analyses revealed that the measures correctly classified 73.6% of the children. 相似文献

Data suggest that children with reading disability (RD) and non-RD children with attention-deficit/hyperactivity disorder (ADHD) may comprise distinct subgroups. Research has been hampered by variance in definitional criteria, which results in the study of different subgroups of children. Using cluster analysis, this study empirically divided children with ADHD (N = 54), based on their Full Scale IQ (FSIQ) and reading ability. Four distinct subgroups emerged in which cognitive, behavioral, and neurochemical function was compared. Cluster 1 was of average FSIQ and reading scores; Cluster 2 was of average FSIQ but showed impairment in reading; Cluster 3 had high FSIQ and reading scores; and Cluster 4 had low scores in both domains. The groups had different patterns of cognitive, behavioral, and neurochemical function, as determined by discrepancies in Verbal-Performance IQ, academic achievement scores, parent aggression ratings, and a measure of noradrenergic function. These distinctions are discussed with regard to etiology, treatment, and long-term outcome. 相似文献

Clinical and psychoeducational data were analyzed for 119 children ages 8 to 16 years who were evaluated in a child diagnostic clinic. A learning disability (LD) was present in 70% of the children with attention-deficit/hyperactivity disorder (ADHD), with a learning disability in written expression two times more common (65%) than a learning disability in reading, math, or spelling. Children with LD and ADHD had more severe learning problems than children who had LD but no ADHD, and the former also had more severe attention problems than children who had ADHD but no LD. Further, children with ADHD but no LD had some degree of learning problem, and children with LD but no ADHD had some degree of attention problem. Results suggest that learning and attention problems are on a continuum, are interrelated, and usually coexist. 相似文献

This article discusses the relationship between attention deficit-hyperactivity disorder (ADHD) and learning disability (LD). The relevant literature is outlined, and empirical data are presented from a prospective follow-up study of 600 speech/language-impaired children. The data show an increased prevalence of both LD and ADHD among children with early speech/language impairments. Furthermore, LD was strongly associated with ADHD in both the initial and follow-up samples. Also, the children with LD had increased rates of other psychiatric disorders (e.g., behavior disorders, mood disorders, anxiety disorders). The implications of these data are discussed with regard to the possible etiology of the ADHD-LD association, treatment for children with LD and ADHD, and promising hypotheses for future research. 相似文献

This study compared learning and study strategies of students with attention‐deficit/hyperactivity disorder (ADHD) to two groups: college students with learning disabilities (LD) and college students without disabilities. In addition, strengths and weaknesses within the ADHD group were examined on the Learning and Study Strategies Inventory, 2nd edition (LASSI; C.E. Weinstein & D.R. Palmer, 2002). The LASSI was also evaluated as a predictive measure for academic achievement for college students with ADHD compared to other students. Results indicate that several important differences may exist in the learning and study strategies of students with ADHD versus students with LD and students without disabilities. However, the LASSI may not be a useful tool for predicting academic achievement for college students with ADHD. Interventions for working with students with ADHD are given. © 2007 Wiley Periodicals, Inc. 相似文献

Concurrent validity of the Kaufman Brief Intelligence Test (K-BIT) with the Wechsler Intelligence Scale for Children-Third Edition (WISC-III) was evaluated, as well as the K-BIT's accuracy as a predictor of WISC-III scores, in a sample of young children with reading disabilities. The two measures were administered to 65 children from Atlanta, Boston, and Toronto who ranged from 6-5 to 7-11 years of age at testing. Correlations between the verbal, nonverbal, and composite scales of the K-BIT and WISC-III were .60, .48, and .63, respectively. Mean K-BIT scores ranged from 1.2 to 5.0 points higher than the corresponding WISC-III scores. Standard errors of estimation ranged from 10.0 to 12.3 points. In individual cases, K-BIT scores can underestimate or overestimate WISC-III scores by as much as 25 points. Results suggest caution against using the K-BIT exclusively for placement and diagnostic purposes with young children with reading disabilities if IQ scores are required. 相似文献

The possible utility of Wechsler's Deterioration Index (WDI) in analyzing children's Wechsler Intelligence Scale for Children-Revised (WISC-R) results was explored in this study. Clinical records of children with learning disabilities (LD) and children with attention deficit-hyperactivity disorder (ADHD) were reviewed to determine if the WDI predicted the presence or severity of the disorders. The ages of the children ranged from 6 to 14. In two independent samples of children with LD (n = 35 and n = 26), the WDI did not predict LD status or severity. The LD samples were mostly male--85% and 57%, respectively. However, the WDI scores did significantly distinguish children with ADHD (n = 10) from nondisabled children (n = 10). The results were cross-validated on an independent sample of children with ADHD (n = 17) when compared to non-ADHD children (n = 22) who experienced significant behavioral difficulties. The ADHD samples were also mostly male--90% and 89%, respectively. The WDI classified only 59% of the children with ADHD and 86% of the non-ADHD children correctly. It is recommended that the WDI be considered a developmental index rather than a deterioration index in children. It is also recommended that significant WDI elevation (greater than .20) be considered to raise the question of ADHD, rather than simply yielding a diagnosis of ADHD. 相似文献

Researchers have found that students with learning disabilities (LD) obtain statistically higher scores on measures of depression than their peers without LD. However, what is not known is whether students with LD display greater levels of clinical depression than their peers without LD. If they do, then special education services should address this area of concern. If they do not, then the current mental health system may be adequate to treat children and adolescents with depression regardless of whether they have concomitant LD. The purpose of this study was to meta-analyze the data-based literature and quantify mean differences in depression measure scores and levels of clinical depression between students with and without LD. 相似文献

The current study examined the ability of children diagnosed as having Attention‐Deficit Hyperactive Disorder (ADHD) with and without a learning disability to perceive nonverbal social cues in comparison to their non‐ADHD peers. In addition, teacher ratings of students' social perceptions were obtained. Participants in the study were 45 students between the ages of seven and ten years who were identified as 1) ADHD only, 2) ADHD with a learning disability (ADHD/LD), and 3) a control group with no diagnosis. The Diagnostic Analysis of Nonverbal Accuracy(DANVA) and the Social Perception Behavior Rating Scale(SPBRS) were used to measure social perceptions. The DANVA was administered twice to each child in the ADHD and ADHD/LD groups: once while the ADHD and ADHD/LD participants were on medication and once off medication. The ADHD/LD group demonstrated significant difficulty in comparison to their peers in perceiving paralanguage cues effectively. The ADHD/LD group also showed significant improvement on the Postures and Paralanguage subtests during on‐medication conditions. © 1999 John Wiley & Sons, Inc. 相似文献

The study presented here investigated the performance of children with learning, psychiatric, and attentional disabilities on the Stroop Color and Word Test. Forty‐three children diagnosed with a full battery of tests as learning disabled (LD [reading]) in grades K through 6 were matched on age, gender, ethnicity, and grade with 43 normal controls. They were also matched with groups of 43 children with psychiatric disorders and 43 children with attentional problems. All subjects were given the Stroop test, which took about 4 minutes per subject. The results indicated clear differences between the groups, with the LD and the psychiatric/attention deficit/hyperactivity disorder (ADHD) groups generating unique profiles different from the normal controls. The children with LD showed slower reading speed and less interference, while the subjects with ADHD and diagnoses showed impairment only on the Color‐Word score. A discriminant analysis using the three basic Stroop scales was able to significantly differentiate the LD group from the non–learning‐disabled (NLD) group (89%) and the LD group from a joint Psychiatric/ADHD group (86%). However, results were poorer for differentiating a joint LD/ADHD group from the NLD group (68%) and the LD from the ADHD group (59%). © 2002 Wiley Periodicals, Inc. 相似文献

The purpose of this study was to investigate the occurrence and severity of reading, spelling, and written language impairment
in children clinically referred for Attention Deficit Hyperactivity Disorder (ADHD). Specific questions involved 1) whether
ADD subgroups with and without hyperactivity differ in reading, spelling, and written language achievement, 2) whether age
and gender interact with ADD sub-group class to affect reading/written language achievement, and 3) whether prevalence of
impaired reading/written language in these subgroups is consistent with previous reports in heterogeneous samples. Subjects
were 115 ADD children aged 6-12 who were subclassified as ADD + H(72 percent) and ADD - H(28 percent) by objective teacher
ratings. Dependent measures included tests of single word recognition and vocabulary, word attack, contextual comprehension,
written spelling, written sentence construction, and writing fluency, in addition to a structured behavioral observation,
during which aspects of inattention and motor activity were coded. A large fraction of this sample met public school LD criteria
(54 percent), and achievement on most measures was globally poorer than the respective test normative groups. The ADD + H
subgroup showed significantly poorer word attack skills, while the subgroups did not significantly differ from each other
on other reading/written language measures. However, 17 percent of the total ADD sample were ≥ 1.5 SD below the mean in total
reading achievement, and 29 percent were ≥ 1.5 SD below the mean on measures of written spelling/language. Gender X age interactions,
indicating poorer performance in the middle age group of females, were likely related to lower IQ. 相似文献

As part of a mandated three-year reevaluation, the Differential Ability Scales (DAS) was administered to 53 children identified as having a learning disability approximately 3 years after each had been administered the Wechsler Intelligence Scale for Children—Third Edition (WISC-III). The DAS's General Conceptual Ability score (GCA), and Verbal and Spatial Cluster scores were nonsignificantly different from the WISC-III's Full Scale, Verbal, and Performance scores. The Nonverbal Reasoning score of the DAS (a measure of Fluid intelligence not assessed by the WISC-III) was significantly different from both the Verbal and Performance scores. High correlations were found between the similar constructs on the two tests. Approximately 96% of the students obtaining a certain classification from the WISC-III obtained a comparable classification from the DAS. © 1996 John Wiley & Sons, Inc. 相似文献

This study assessed rates of learning disabilities (LD) by several psychometric definitions in children with epilepsy and identified risk factors. Participants (N = 173, ages 8-15 years) completed IQ screening, academic achievement testing, and structured interviews. Children with significant head injury, chronic physical conditions, or mental retardation were excluded. Using an IQ-achievement discrepancy definition, 48% exceeded the cutoff for LD in at least one academic area; using low-achievement definitions, 41% to 62% exceeded cutoffs in at least one academic area. Younger children with generalized nonabsence seizures were at increased risk for math LD using the IQ-achievement discrepancy definition; age of seizure onset and attention-deficit/hyperactivity disorder (ADHD) were risk factors for reading and math LD using low-achievement definitions. Writing was the most common domain affected, but neither ADHD nor seizure variables reliably identified children at risk for writing LD. Although children with earlier seizure onset, generalized nonabsence seizures, and comorbid ADHD appear to be at increased risk for some types of LD by some definitions, these findings largely suggest that all children with epilepsy should be considered vulnerable to LD. A diagnosis of epilepsy (even with controlled seizures and less severe seizure types) should provide sufficient cause to screen school-age children for LD and comorbid ADHD. 相似文献
