Analysis of cognitive abilities for learning disabled children

The study investigated WISC-R subtest pattern scores of 58 learning disabled children (42 boys and 16 girls) ranging in age from 6 years to 15 years, 10 months. The variation in subtest scores was analyzed by a 1 X 10 analysis of variance with repeated measures on the single factor. Differences between individual subtest means were analyzed by the Newman-Keuls test for simple effects. The evidence indicates that the low subtest scores on Arithmetic, Coding and Information were characteristic of this group. The study did not support the verbal-Performance discrepancies as useful in the diagnosis of learning disabilities.     

Behavioural and emotional problems in hearing impaired children: a preliminary study of teacher and parent ratings

A case study of what appears to be an inclusive classroom in Sweden is reported. The group of children in the class studied was very heterogeneous: five of the 15 children had a disability diagnosis at the time of the study. One aim of the study was to develop a methodology which can be used in order to investigate in what sense classrooms are ‘inclusive’, especially as regards the point of view of the pupils. It is argued that an explicit definition of characteristics of inclusive classrooms and clear‐cut methods to study those characteristics are necessary prerequisites in order to reach valid conclusions concerning what teaching strategies are central to inclusive processes. The data consist of interviews with the teachers and children involved, sociograms, a questionnaire answered by the children, notes from participant observations and poetry by the children. The analyses suggest that the classroom seems to be inclusive, although it is emphasised that this is not an all‐or‐none phenomenon, especially children's experiences are complex phenomena. It is argued that the teachers try to create a learning community where differences are valued. Six teacher strategies emerged from the data.     

Usefulness of cognitive intervention programmes for socio-emotional and behaviour problems in children with learning disabilities

Behavioural and emotional problems occur more frequently in children with learning problems than in a cross-section of the general population, both at home and at school. While behaviour problems reportedly are a key obstructive factor impeding inclusive education, children with both behavioural and learning disabilities carry a high risk of social exclusion and school dropout when they are in mainstream environments. Meta-analyses indicated only a moderate impact of social skills training. To see what kind of intervention programme would be effective in modifying cognitive as well as socio-emotional behaviour and at the same time focusing on contextual interaction and intervention, a pilot study has been carried out in Belgium with 11–13-year-old students with learning disability and behaviour problems in special schools. A total of 24 children in the experimental group were matched against a control group of 24. Children in the experimental group, after having received 14 lessons of FIE (Feuerstein's Instrumental Enrichment Programme), showed a marked increase in some cognitive functions (hypothetical thinking, perception and understanding of humour) but not in others. A significant effect on socio-emotional behaviour could not be shown quantitatively, but was evident from qualitative interviewing. The mediating attitude of the teachers was a key influencing factor in producing lasting changes. Programmes such as FIE, provided they address children as well as teachers in a comprehensive way, focusing on cognitive as well as socio-emotional behavioural changes, may become powerful instruments to help children as well as teachers in a highly differentiated inclusive school environment.     

Sustained and selective attention in children with learning disabilities

Sustained and selective attention of 30 fourth-, fifth-, and sixth-grade students with learning disabilities (LD) and 20 controls were compared. A continuous performance test (CPT) yielded no differences for students with LD and controls, suggesting similar ability for both groups in sustaining attention and inhibiting impulsive responding. Subjects with LD made more errors than controls on a selective attention task when letter distractors were adjacent to the target letter but not when they were distant, and more correct responses than controls when facilitating letters were adjacent to the target, suggesting that students with LD are less able to narrow the focus of their attention. Longer response times by students with LD indicate that they have slower information-processing skills than controls. Regrouping students according to teacher ratings for attention deficit-hyperactivity disorder (ADHD) yielded the customary impulsive response set on the CPT and more errors on the selective attention task, but no differences on response times for students with ADHD. LD students with ADHD made more errors than LD students without ADHD when letter distractors were adjacent to the target letter.     

Assessment of attention in school children: teachers' ratings related to tests of attention

The paper provides (1) a teacher-administered rating instrument for inattention without confounding the rating with hyperactivity and conduct disorder, and (2) evidence that the ratings correlate with the scores obtained from cognitive tests of attention. In Study I, the first objective was to investigate the construct validity and the inter-rater reliability of the Attention Checklist (ACL) by factor analysing the teacher ratings of 110 Grade 4 children, obtained by using the ACL. The second objective was to investigate the predictive validity of the ACL by examining the relationship between the scores obtained for the participants from teachers' ratings using the ACL and the scores obtained by participants in the lab-type attention tests. The results of factor analysis showed that a single factor labelled ‘inattention’ underlies the 12 items in the ACL. Examining the differences in performance on attention tests, the ‘low attention’ children as rated by the teachers on the ACL scored lower than the ‘high attention’ children on the objective tests of attention. These findings were replicated in Study II, which was conducted to test further the construct validity and predictive validity of the ACL. This time, only those two tests (Auditory Attention and Visual Attention) that had shown relatively poor discrimination between the high and low attention groups in Study I were, again, administered to another cohort of 97 Grade 4 children, as it was our intention to further challenge the reliability of the ACL. Overall, the results of both studies suggest that comprehensive assessment of attention skills should include both ACL and objective measures of selective attention.     

Scientific reasoning in elementary school children: Assessment and relations with cognitive abilities

The primary goal of this study was the broad assessment and modeling of scientific reasoning in elementary school age. One hundred fifty-five fourth graders were tested on 20 recently developed paper-and-pencil items tapping four different components of scientific reasoning (understanding the nature of science, understanding theories, designing experiments, and interpreting data). As confirmed by Rasch analyses, the scientific reasoning items formed a reliable scale. Model comparisons differentiated scientific reasoning as a separate construct from measures of intelligence and reading skills and revealed discriminant validity. Furthermore, we explored the relationship between scientific reasoning and the postulated prerequisites inhibitory control, spatial abilities and problem-solving skills. As shown by correlation and regression analyses, beside general cognitive abilities (intelligence, reading skills) problem-solving skills and spatial abilities predicted performance in scientific reasoning items and thus contributed to explaining individual differences in elementary school children's scientific reasoning competencies.     

In pursuit of the elusive relationship between selected cognitive abilities and learning

The present research consists of two experiments that attempt to produce differential learning-ability relationships on the basis of selected learning task variations. In the first experiment, 120 5th-graders performed a cued recall task under one of three instructional conditions. In the second, 144 10th-graders recalled items of high and low meaningfulness under constrained or free conditions of recall. Although the task variations produced mean performance differences, the expected patterns of covariation between learning and the ability markers of reasoning, spatial ability, and digit span did not materialize. These results, taken with those of previous investigations, suggest that the nonreplicability characteristic of this domain may be traced to the relatively impure sources of individual differences variance associated with psychometric abilities.     

Self-efficacy and cognitive achievement: implications for students with learning problems

This article presents a self-efficacy model of achievement that comprises entry characteristics, self-efficacy for learning, task engagement variables, and efficacy cues. Students' sense of self-efficacy for learning is influenced as they work on tasks by cues that signal how well they are learning. Research is summarized on the effects of social and instructional variables on self-efficacy and achievement behaviors. Empirical evidence supports the idea that self-efficacy predicts student motivation and learning. Future research directions are provided, along with educational implications for students with learning problems.     

A study of the relationship between learning styles and cognitive abilities in engineering students

Learning preferences have been indirectly linked to student success in engineering programmes, without a significant body of research to connect learning preferences with cognitive abilities. A better understanding of the relationship between learning styles and cognitive abilities will allow educators to optimise the classroom experience for students. The goal of this study was to determine whether relationships exist between student learning styles, as determined by the Felder-Soloman Inventory of Learning Styles (FSILS), and their cognitive performance. Three tests were used to assess student's cognitive abilities: a matrix reasoning task, a Tower of London task, and a mental rotation task. Statistical t-tests and correlation coefficients were used to quantify the results. Results indicated that the global–sequential, active–referential, and visual–verbal FSILS learning styles scales are related to performance on cognitive tasks. Most of these relationships were found in response times, not accuracy. Differences in task performance between gender groups (male and female) were more notable than differences between learning styles groups.     

Construction play and cognitive skills associated with the development of mathematical abilities in 7-year-old children

Construction play is thought to develop logico-mathematical skills, however the underlying mechanisms have not been defined. In order to fill this gap, this study looks at the relationship between Lego construction ability, cognitive abilities and mathematical performance in 7-year-old, Year 2 primary school children (N = 66). While studies have focused on the relationship between mathematics performance and verbal memory, there are limited studies focussing on visuospatial memory. We tested both visuospatial and verbal working memory and short term memory, as well as non-verbal intelligence. Mathematical performance was measured through the WIAT-II numerical operations, and the word reading subtest was used as a control variable. We used a Lego construction task paradigm based on four task variables found to systematically increase construction task difficulty. The results suggest that Lego construction ability is positively related to mathematics performance, and visuospatial memory fully mediates this relationship. Future work of an intervention study using Lego construction training to develop visuospatial memory, which in turn may improve mathematics performance, is suggested.     

Effects of methylphenidate on the auditory processing abilities of children with attention deficit-hyperactivity disorder.

Stimulant medications are widely used as part of the treatment for children with attention deficit-hyperactivity disorder (ADHD). The current study investigated the effects of methylphenidate on auditory vigilance, auditory processing abilities, and receptive language abilities of children with ADHD. Twenty subjects (17 males and 3 females) ranged in age from 7 to 13 years. Each subject had been diagnosed as having ADHD and had been prescribed methylphenidate for the control of hyperactivity. The test battery included the Auditory Continuous Performance Test (ACPT), SCAN (a screening test for auditory processing disorders in children), and the Token Test for Children. Results indicated that there was significant improvement in the children's performance on all measures when on methylphenidate. Implications of these findings are discussed.     

Dissociation predicts later attention problems in sexually abused children

OBJECTIVE: The goals of this research are to develop and test a prospective model of attention problems in sexually abused children that includes fixed variables (e.g., gender), trauma, and disclosure-related pathways. METHODS: At Time 1, fixed variables, trauma variables, and stress reactions upon disclosure were assessed in 156 children aged 8-13 years. At the Time 2 follow-up (8-36 months following the initial interview), 56 of the children were assessed for attention problems. RESULTS: A path analysis involving a series of hierarchically nested, ordinary least squares multiple regression analyses indicated two direct paths to attention problems including the child's relationship to the perpetrator (beta=.23) and dissociation measured immediately after disclosure (beta=.53), while controlling for concurrent externalizing behavior (beta=.43). Post-traumatic stress symptoms were only indirectly associated with attention problems via dissociation. Taken together, these pathways accounted for approximately 52% of the variance in attention problems and provided an excellent fit to the data. CONCLUSIONS: Children who report dissociative symptoms upon disclosure of CSA and/or were sexually abused by someone within their family are at an increased risk of developing attention problems. PRACTICE IMPLICATIONS: Findings from this study indicate that children who experienced sexual abuse at an earlier age, by someone within their family, and/or report symptoms of dissociation during disclosure are especially likely to benefit from intervention. Effective interventions should involve (1) providing emotion regulation and coping skills; and (2) helping children to process traumatic aspects of the abuse to reduce the cyclic nature of traumatic reminders leading to unmanageable stress and dissociation.     

Number magnitude processing and basic cognitive functions in children with mathematical learning disabilities

The study sought out to extend our knowledge regarding the origin of mathematical learning disabilities (MLD) in children by testing different hypotheses in the same samples of children. Different aspects of cognitive functions and number processing were assessed in fifth- and sixth-graders (11–13 years old) with MLD and compared to controls. The MLD group displayed weaknesses with most aspects of number processing (e.g., subitizing, symbolic number comparison, number-line estimation) and two cognitive functions (e.g., visual–spatial working memory). These findings favor the defective approximate number system (ANS) hypothesis, but do not fit well with the access deficit hypothesis. Support is also provided for the defective object-tracking system (OTS) hypothesis, the domain general cognitive deficit hypothesis and to some extent the defective numerosity-coding hypothesis. The study suggests that MLD might be caused by multiple deficits and not a single core deficit.     

Reading and cognitive abilities: Longitudinal studies of brain and behavior changes in young children

This paper focuses on methods useful for identifying differences in the development of language reading abilities in children that rely on measures of brain responses and behavioral assessments. Findings from longitudinal and cross-sectional studies using brain and behavior measures are described, along with findings from research designed to influence changes in brain and behavioral responses through training. The findings show differences in event-related potentials (ERP) responses recorded at birth that are related to a child’s later performance on language and reading tasks. Such findings point to a strong biological influence on the development of language and reading skills. However, other findings show that the influence of biological factors on brain processing can be modified through learning. In fact, several studies show that even brief periods of stimulation and opportunities for learning can produce changes in the brain’s ERP repsonses. Such findings suggest that new approaches to evaluating the effectiveness of interventions might change the rate and likelihood of developmental changes.
