Patterns of performance on the Stroop Color and Word Test in children with learning,attentional, and psychiatric disabilities

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.     

Detection of deficits in temporal pattern discrimination using the seashore rhythm test in young children with reading impairments

A deficiency in temporal pattern discrimination frequently is a distinguishing characteristic of children with dyslexia or learning disabilities (LD). We studied the feasibility of using the Seashore Rhythm Test, a subtest of the Halstead-Reitan neurological assessment battery (Halstead, 1947), with young children to discriminate children with reading impairments from age-matched controls reading at a normal level, in an effort to develop tools to determine readiness to read in young school-age children. Major considerations in test selection were ease of administration and wide use and acceptance. Fifty-nine children in Grades 1 through 3 were administered a battery of tests during the last 3 weeks of the school year by blinded experimenters. Tests administered included the Seashore Rhythm Test, Benton Visual Retention Test, Peabody Picture Vocabulary Test, Blau Torque Test, and the Rod and Frame Test. Children with reading impairments (n = 24) in all age groups were found to exhibit a marked deficit in the ability to discriminate patterned pairs of tones on the Seashore Rhythm Test compared to controls (n = 26). These children also exhibited deficits in right-left orientation, as indicated by their poor performance on the Blau Torque Test. Performance on the Seashore and the Blau by a group of children diagnosed as learning disabled (n = 9) was similar to the group with reading impairments. No significant differences between controls and children with reading impairments or LD were observed in Rod and Frame or Benton performance. The results suggest that the Seashore Rhythm Test may prove to be a useful tool to detect young children who will later show signs of reading impairment.     

Stimulus gender and emotional difficulty level: their effect on recognition of facial expressions of affect in children with and without LD

The ability to recognize emotions that were easily identifiable and those that were more difficult to identify, as expressed by male and female faces, was studied in 48 nondisabled children and 76 children with learning disabilities (LD) ages 9 through 12. On the basis of their performance on the Rey Auditory Verbal Learning Test and the Benton Visual Retention Test, the LD group was divided into three subgroups: those with verbal (VD), nonverbal (NVD), and both verbal and nonverbal (BD) deficits. A shortened version of Ekman and Friesen's Pictures of Facial Affect, including pictures of both men and women, was the measure of ability to identify facial expressions of affect. Children of both genders in all three groups of children with LD, as well as their normally achieving peers, were more accurate in identifying expressions of affect from female faces, notwithstanding differences in sensitivity to such emotional communication in favor of the nondisabled and VD groups. However, a significant interaction was found between gender and emotional recognition difficulty level, with female faces being more expressive for emotions that were difficult to recognize.     

WISC-R verbal and performance abilities of native american students referred for school learning problems

This study was designed to determine if three diagnostic groups of Navajo children differed on intellectual dimensions as measured by the WISC-R. Subjects had been previously diagnosed by state certified professionals and were identified as nonhan dicapped (NH) (N = 113), educationally disadvantaged.(ED) (N = 189), and learning disabled (LD) (N = 150). NH group means on all WISC-R variables were significantly higher than the LD group means. The ED and the LD group means were similar on the verbal measures, but the LD group scores were lower than the ED group scores on performance measures. The NH group demonstrated intellectual abilities and deficits similar to those reported for other primary-grade Navajo children who had not been referred for suspected handicapping conditions.     

A comparison of children with and without learning disabilities on social problem-solving skill, school behavior, and family background

The study compared 86 children with learning disabilities (LD) with 86 matched children without learning disabilities (NLD) on three domains of variables: social problem-solving skill, teacher-rated school behavior and competence, and family background. The children with LD and the NLD group differed on variables in all three domains. More specifically, the children with LD were able to generate fewer alternatives for solving social problem situations, showed less tolerance for frustration and less adaptive assertiveness, and had more overall classroom behavior problems and less personal and social competence in a variety of areas as rated by teachers. Children having LD also showed more family background difficulties (e.g., lack of educational stimulation at home, economic difficulties). The findings suggest the need for greater attention to social and behavioral remediation for children with LD and greater involvement of their families, in addition to the cognitive and academic remediation emphasized in existing curricula for children with LD.     

Reciprocal Nominations,Reciprocal Rejections and Loneliness among Students with Learning Disorders

The study examined the relations between reciprocal nominations, reciprocal rejections and loneliness among children with learning disorders. The sample consisted of 238 Israeli students: 110 students with learning disorders (LD) and 128 students with no LD (NLD) drawn from 2nd to 6th Grades (ages: M = 9.83 years, SD = 1.35). Participants were assessed on: loneliness, sense of coherence, friendship quality, reciprocal friendship and reciprocal rejection nominations. Hierarchical multiple regression analysis revealed that loneliness experience was significantly predicted by sense of coherence, peer reciprocal rejection and conception of friendship qualities. Students with LD who had at least one reciprocal rejection with a classmate felt more lonely and less coherent than did their NLD peers. Within the LD group, those children who had at least one reciprocal rejection with a classmate felt more lonely and less coherent than did LD children who had no reciprocal rejection. Such significant within‐group differences were not found in the NLD group. The discussion emphasises the importance of the examination of intra‐ and interpersonal variables in the understanding the loneliness experience among LD children, with special focus on the role of reciprocal negative nominations.     

The utility of the key math diagnostic arithmetic test for adolescent learning disabled students

The Key Math Diagnostic Arithmetic Test was administered to 82 learning disabled adolescents. An analysis of the performance of these children revealed that: (a) mean LD performance peaked at approximately the fourth grade level of difficulty; (b) there was marginal variation in performance across the 14 subtests; (c) a strong negative correlation existed between years behind grade level and seven Key Math subtests; (d) the subtests factored into two ability categories, as opposed to the three suggested by the test developers; and (e) LD performance was quite distinct from that of normal children in terms of the types of computational errors made on the test.     

Are working memory deficits in readers with learning disabilities hard to change?

This study investigated whether changes in the working memory (WM) performance of readers with learning disabilities (LD) is related to a general or domain-specific system. The study compared readers with LD, chronologically age-matched (CA-M), and reading level-matched (RL-M) children's WM performance for phonological, visual-spatial, and semantic information under initial (no probes or cues), gain (cues that bring performance to an asymptotic level), and maintenance (asymptotic conditions without cues) conditions. The main findings indicated that (a) CA-M children were superior in performance to readers with LD across initial, gain, and maintenance conditions, (b) readers with LD showed less change (as reflected in effect size scores, slopes for the quadratic curve) on both visual-spatial and verbal (phonological and semantic) WM tasks across gain and maintenance conditions than the CA-matched children, and (c) the performance of readers with LD was superior to the RL-M children's performance on initial conditions, but inferior on gain and maintenance conditions. Taken together, the results suggest that a general system moderated the changes in retrieval of phonological, visual-spatial, and semantic information in readers with LD.     

Coping mediates the relationship between emotional intelligence (EI) and academic achievement

Research examining the relationships between performance measures of emotional intelligence (EI), coping styles, and academic achievement is sparse. Two studies were designed to redress this imbalance. In each of these studies, both EI and coping styles were significantly related to academic achievement. In Study 1, 159 community college students completed the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT) and problem-focused, emotion-focused, and avoidant coping scales. Collectively, the coping variables significantly mediated the relationship between EI and grade point average (GPA) for Emotion Perception, Emotion Facilitation of Thought and Emotion Management (but not for Emotional Understanding). Problem-focused coping was the only single significant mediator, mediating the relationship between emotion management and GPA (but not other branches and GPA). In Study 2, 293 middle school students completed the Situational Test of Emotion Management for Youths (STEM-Y) and scales measuring the same three coping strategies. In this study, the coping variables again significantly mediated the relationship between emotion management and GPA. Once again, problem-focused coping was a significant mediator. Collectively, these results suggest that better educational outcomes might be achieved by targeting skills relating to emotion management and problem-focused coping.     

Self-perceptions, motivation, and adjustment in children with learning disabilities: a multiple group comparison study

This study examined the self-perceptions, motivational orientations, and classroom adjustment of children with learning disabilities (LD), matched-IQ non-LD, randomly selected non-LD, and low achieving children. Elementary-age children (N = 148; 37 from each group) completed domain-specific measures of their self-concepts, perceptions of control, and motivation. Teachers rated children on motivational and competence indices and classroom behavioral adjustment. Comparisons among groups indicated that children with LD were lower in perceived cognitive competence and academic self-regulation relative to the nondisabled control groups, but were comparable to the low achieving children. Children with LD were most likely to perceive academic outcomes as controlled by powerful others. No group differences were found for general self-perceptions of control or competence. Teacher ratings of children with LD were more discrepant from those of comparison groups than were self-ratings of children with LD. The results suggest the need for matched-IQ and low achieving control groups in research on children with LD. The origin and role of both environmental inputs and self-perceptions in the adjustment of students with LD are discussed.     

Fundamental motor skills,nutritional status,perceived competence,and school performance of Brazilian children in social vulnerability: Gender comparison

Being at risk or in social vulnerability situations can affect important aspects of child development. The aim of this study was to investigate fundamental motor skills (locomotor and object control) and school (writing, arithmetic, reading) performances, the perceived competence and the nutritional status of girls and boys living in social vulnerability in the poorest regions of Brazil. Two hundred eleven (211) children (87 girls, 41%), 7–10-year-old (M = 8.3, SD = 0.9), from public schools in Ceará (Brazil), living in social vulnerability, participated in the study. Children were assessed using the Test of Gross Motor Development – 2, the Body Mass Index (BMI), the Self-Perception Profile for Children, and the School Performance Test. Multivariate analysis of covariance (MANCOVA), adjusted for age, did not show any significant effect for locomotion. There was an effect of gender on the object control. Boys showed higher scores in striking, kicking, throwing, and rolling a ball. Quade's nonparametric analysis showed no difference in BMI between the genders. Most children presented healthy weight. The MANCOVA showed no effect of gender on children’s scores on perceived competence on the subscales; moderate scores were found for most children. There were no gender effects on school performance; both boys and girls demonstrated inferior performance. Boys and girls in social vulnerability showed inferior performance in most motor skills, moderate perceived competence and inferior school performance. These results reveal that the appropriate development of these children is at risk and that intervention strategies should be implemented to compensate the difficulties presented.     

Falling through the cracks: rehabilitation services for adults with learning disabilities.

The present study investigated the knowledge and perceptions of vocational rehabilitation (VR) of adults with learning disabilities (LD), as well as control variables which describe adults with LD and may have a bearing on access to VR services. This was accomplished by (1) determining the knowledge adults with LD had of their rights under federal rehabilitation regulations; (2) examining demographic control variables (e.g., sex, age, education level, hometown population, employment history, and income), which may have a bearing on the need for or access to VR services by adults with LD; and (3) examining experiences/perceptions of adults with LD regarding the VR application/eligibility process. A pretested questionnaire appeared in the January 1989 ACLD Newsbriefs. Findings indicate that while there was a group of respondents who were satisfied with the rehabilitation services they had received, there was also a large group of respondents who were either ineligible for rehabilitation services or dissatisfied with services they received. Generally, respondents' knowledge of VR was limited.     

Cognitive functioning in learning-disabled and nonlearning-disabled secondary level students

A study was conducted to compare on a number of specialized cognitive procedures the performance of high school students designated as learning disabled (LD) with the performance of nonlearning-disabled students experiencing learning difficulties (nonLD). Both groups were then compared with a control group of typical learners. Results indicate that when taken as a group LD and nonLD students differed significantly from a control group of typical learners on 6 of 16 variables. LD students differed from nonLD students with learning difficulties on 5 of 16 variables. The performance of LD and nonLD students with learning difficulties indicates patterns of cognitive functioning that differ from those of typical learners. The possibility of the development of compensatory cognitive styles in LD and nonLD students and their implications are discussed.     

Cognitive functioning as measured by the WISC-R: do children with learning disabilities have distinctive patterns of performance?

Patterns of performance on the Wechsler Intelligence Scale for Children-Revised (WISC-R) have been proposed as useful tools for the identification of children with learning disabilities (LD). However, most of the studies of WISC-R patterns in children with LD have been plagued by the lack of a typically achieving comparison group, by failure to measure individual patterns, and by the lack of a precise definition of LD. In an attempt to address these flaws and to assess the presence of patterns of performance on the WISC-R, we examined data from 121 children with typical achievement (TA), 143 children with reading disabilities (RD), and 100 children with a specific arithmetic disability (AD), ages 6 to 16 years. The results indicated that the RD and AD groups had significantly lower scores than the TA group on all the Verbal IQ subtests. Many of the children with AD and RD showed a significant difference between Verbal and Performance IQ scores, but so did many of the typically achieving children. Although there were some children with LD who showed the predicted patterns, typically, 65% or more of the children with LD did not. Furthermore, a proportion of the TA group-generally not significantly smaller than that of the RD and AD groups-showed discrepancy patterns as well. Our results indicate that the patterns of performance on intelligence tests are not reliable enough for the diagnosis of LD in individual children. Therefore, it might be more profitable to base the detection of an individual's LD on patterns of achievement test scores.     

LD status and achievement: confounding variables in the study of children's social status, self-esteem, and behavioral functioning

The purpose of the present study was to examine the role of achievement in explaining the poor social and behavioral functioning associated with LD status, and to evaluate potential gender differences in patterns of interpersonal functioning among youth with learning disabilities (LD) and nondisabled (NLD) youth. Thirty-two students with learning disabilities (21 boys, 11 girls) were matched with same-sex, same-race classmates whose reading achievement was low (LA) or average (AA), and these groups were compared on peer ratings of liking and disliking, perceptions of self-worth and social acceptance, and teacher ratings of conduct problems, anxiety-withdrawal, and attention problems. Students with learning disabilities were less accepted and less well-liked than children in the LA or AA groups and also perceived their self-worth and social acceptance to be lower than LA or AA students. Group by Sex interactions were apparent for several of the peer rating and behavioral variables, indicating that different patterns of social and behavioral functioning distinguished LD boys and LD girls from their NLD peers. The findings highlight the potential role of low achievement in peers' dislike of LD girls and suggest the importance of investigating well-defined subgroups of youth with LD in future research.     

Two approaches to teaching young children science concepts,vocabulary, and scientific problem-solving skills

The present study examined the efficacy of two different approaches to teaching designed to facilitate children's learning about science concepts and vocabulary related to objects’ floating and sinking and scientific problem-solving skills: responsive teaching (RT) and the combination of responsive teaching and explicit instruction (RT + EI). Participants included 104 children (51 boys) aged four to five years. Small groups of children were randomly assigned to one of the two intervention groups (RT, RT + EI) or to a control group. Responsive teaching (RT) reflects a common approach to teaching young children, and the combination approach (RT + EI) includes explicit instruction as well as responsive teaching. The two planned interventions were implemented with preschool children and provided evidence that (1) young children learned science concepts and vocabulary better when either responsive teaching or the combination of responsive teaching and explicit instruction was used; (2) children in the combined intervention group learned more science concepts and vocabulary and more content-specific scientific problem-solving skills than children in either the responsive teaching or control groups. Limitations, future directions, and implications for practice are also discussed.     

An operational definition of learning disabilities (cognitive domain) using WISC full scale IQ and peabody individual achievement test scores

An operational index of discrepancy to assist in identifying learning disabilities (LD) in the cognitive domain was derived using the Full Scale IQ, Wechsler Intelligence Scale for Children (Wechsler, 1949, and relevant subtest scores on the Peabody Individual Achievement Test (PIAT) (Dunn and Markwardt, 1970. The index was applied to all legally identified LD children (N = 60) of a Michigan county who were in the LD program (1% of the total elementary school population of 6000 children). Of the 50 males and 10 females (mean age: 9 years 2 months; mean IQ: 91), the index identified 74% and 30% respectively as may be LD in the cognitive domain. This comprised 67% of the 60 children, or 2/3 of 1 % of the total elementary school population. Of the 67% may be LD children, 93% had discrepancy low PIAT subtest scores in Reading Recognition, 88% in Reading Comprehension, 83% in Spelling, and 52% in Arithmetic. Considerable caution should be exercised when classifying children, especially females, as LD.     

Differences that make a difference: comparisons of metacomponential functioning and knowledge base among groups of high and low IQ learning disabled, mildly mentally retarded, and normally achieving adults

To determine if cognition among persons with learning disabilities (LD) and mild mental retardation (MMR) is similar, we compared metacomponential functioning and knowledge acquisition across groups of incarcerated adults with LD and high IQ (HIQLD), with LD and low IQ (LIQLD), with normal achievement (NA), and with MMR. The Slosson Intelligence Test Computer Report (Nicholson, 1984) formula established criteria for group inclusion. Metacomponential functioning among 77 males and 26 females was measured by a confidence test (Echternacht, Boldt, & Sellman, 1971) designed for the general knowledge subtest of the SRA Achievement Battery (Naslund, Thorpe, & Lefever, 1982). Knowledge base and group membership were significantly related to metacomponential ability (R2 = .84). Persons with HIQLD and LIQLD performed better than those with MMR on both measures. The HIQLD, however, did not outperform their peers with NA. Results show that (a) knowledge base is the best predictor of metacomponential skill, (b) metacomponential orchestration differentiates persons with HIQLD from those with LIQLD and both groups from persons with MMR, and (c) IQ mediates metacognition, but does not explain it. Education should emphasize knowledge acquisition for people with HIQLD; people with LIQLD and MMR require more attention to metacognition.     

Taiwanese families' perspectives on learning disabilities: an exploratory study in three middle schools

The purpose of this study was to investigate families' perspectives on learning disabilities (LD) in Taiwan. A researcher‐designed survey was sent out to families of children with or without LD from three middle schools. Data from 153 participants were gathered and analysed. The survey consisted of four sections, namely demographic information, children's reading performance, families' general understanding and perspectives of LD. Specifically, the last section of 54 Likert scale items designed to gather information about families' perspectives of LD was analysed with five domains: causes of LD (inherent or acquired), conceptions and misconceptions, attitudes (acceptance or rejection), disclosure of disabilities (willing or unwilling), and support. Results indicated that families were not familiar with educational services related to LD in schools. Additionally, families' experiences with people with disabilities resulted in different perspectives regarding the causes and conceptions about LD, and acquiring support. Families' perspectives on LD also correlated with personal characteristics, including the level of their children's reading performance, number of children and income level. The cultural implications of these findings interplay with an emphasis on academic performance are discussed.     

Language problems in children with learning disabilities: do they interfere with maternal communication?

In this study, parent-child interaction in two carefully matched subgroups-school-age boys with learning disabilities (LD) who showed a discrepancy between their verbal IQ and performance IQ and had more extensive difficulties in higher-level language abilities (VIQ < PIQ, n = 8) and boys with LD who did not manifest a discrepancy between verbal IQ and performance IQ (VIQ = PIQ, n = 8), were investigated. The effects of the child's language problems on child task performance and on the quality of maternal communication were analyzed in a mother-child problem solving task. Children in the VIQ < PIQ group were found to be less successful on the task than children in the VIQ = PIQ group, and their mothers exhibited lower communication clarity in their instructions than the mothers of the children in the VIQ = PIQ group. An interesting interaction effect was found for communication deviances. For mothers in the VIQ < PIQ group the extent of deficient communication increased from the monologue to the dialogue situation, whereas communication deviances decreased for mothers in the VIQ = PIQ group. Three possible models are discussed in light of the differences between the subgroups.
