Depression and achievement in subgroups of children with learning disabilities

Eighty-five learning disabled children were assigned to four subgroups and administered measures designed to assess the relationship between depression and academic achievement. As a group, these children were more depressed than nondisabled children. The subgroups, which were identified as learning disabled only, learning disabled with low IQ, learning disabled with socio-emotional disturbance, and learning disabled with hyperactivity, did not differ in magnitude of depression; however, the relationships between depression and achievement and IQ were substantially different in each subgroup. For the two largest subgroups, learning disabled only and learning disabled with socio-emotional disturbance, it was suggested that depression is the consequence of learning failure in the former and a possible cause of learning failure in the latter. These findings underscore the importance of depression, a heretofore neglected variable, for the understanding and remediation of learning disabilities.     

Relationship between intelligence and vocabulary

This study explored the correlations of scores on the Wechsler Intelligence Scale for Children-III in screening language problems and scores on the three Comprehensive Receptive and Expressive Vocabulary Test subscales. Participants were 243 students ages 6 to 17 years in Grades K-11 who were identified as learning disabled, learning disabled with speech impairment, mentally retarded, and speech impaired. Analysis indicated strong correlations between the two measures, particularly between the CREVT General Vocabulary and WISC-III Verbal IQ (r = .80), WISC-III Verbal Comprehension Index (r =.83), and the Vocabulary subtest (r =.76). These results held across the grades. Supporting earlier studies of relationships of Verbal IQ and Receptive Vocabulary, correlations were lower between participants in Grades K through 2 than those in higher grades on the WISC-III Verbal IQ and the Receptive Vocabulary subtest. An analysis of the accuracy of the WISC-III for classifying students with language problems indicated improvement in classification over chance. These findings suggest that the WISC-III may be an effective screen for language problems.     

WORD RECOGNITION SKILLS OF LEARNING DISABLED CHILDREN AND AVERAGE STUDENTS’

Abstract

The ability of learning disabled and average students’ to recognize and identify words was investigated. Two informal reading measures, the Sundbye Minimal Contrast Phonics Test and an oral reading sample, were administered to three groups. The groups were composed of learning disabled students evidencing reading problems (LD), average students matched with the learning disabled group on reading level and IQ (YN), and average students matched with the learning disabled group on chronological age and IQ (ON). The LD group and average readers did not differ on identification of symbol‐sound associations, word recognition proficiency, the ability to detect and correct word recognition errors, and the ability to use information within the text to recognize words. However, the LD and ON group differed on mean number of word recognition errors. Educational implications of the findings were discussed and a profile of the word recognition skills of learning disabled children was presented.     

Effects of A Training Program on Teacher Behavior and Handicapped Children's Self-Concepts

The purpose of this research was to assess the effectiveness of the revised Utah State University Self-Concept Protocol Program in changing teacher behaviors presumed to be related to pupil self-concept. This program was focused on teachers with handicapped pupils in mainstreamed classrooms (grades 4 through 6). Ten volunteer teachers were trained in the self-concept behaviors as part of an inservice course. Eight additional volunteer teachers served as a no-treatment control group. Program-related teacher behaviors were observed and a pupil self-concept measure was administered before and after the inservice course. Results indicated that, although no changes occurred in program-related behaviors for the control group teachers, experimental group teachers showed significant increases on six of the 12 program-related behaviors. No gains in self-concept were made by handicapped children; however, there was some evidence for differential effectiveness of the program for learning disabled and emotionally handicapped children.     

The diagnostic value of cerebellar-vestibular tests in detecting learning disabilities, dyslexia, and attention deficit disorder

Neurological and optokinetic measures of cerebellar-vestibular (CV) dysfunctioning were shown to be of significant diagnostic value in differentiating between learning disabled subjects and controls matched for chronological age, sex, handedness, IQ, and background (ns = 35). Although traditionally used electronystagmographic positional and caloric parameters were not similarly discriminating, quantitative measures of vertical nystagmus in various eyes-closed positions appeared to have diagnostic potential and were related significantly to such CV-determined neurological signs as positive monopedal Romberg. As a substantial majority of learning disabled (82.9%) evidenced ADD-like symptoms and since learning disabled subsamples with and without Attention Deficit Disorder (ADD) shared similar coexisting symptoms and CV signs, it appeared probable that learning disabilities and ADD were reflections of the same underlying CV determinants.     

A longitudinal study of bilingual and cognitive development(1)

This paper presents the findings of a longitudinal study of IQ data collected over a 5-year period (Grades K-4) on pupils enrolled in a French immersion program (anglophone pupils receiving all instruction in French except English language arts) and pupils in the regular English program. Although year-by-year results may fail to show IQ differences between the two groups, repeated measures analysis indicates that the immersion group has a higher IQ measure over the 5-year period. However, considering Grades 1–3 only, which involved the administration of the same test, the two groups do not score differentially with respect to either overall IQ measure or specific subtest scores (classification/categorization, analogies, following of verbal directions) when scores are adjusted for initial IQ (and age) differences, thus failing initially to support studies which show positive relationships between bilingualism and cognitive functioning. However, supportive of those studies is a further analysis on the data of immersion pupils classified as “high” French achievers vs. “low” French achievers. The high French achievers obtain significantly higher IQ measures and subtest scores (analogies and following of verbal directions) than the low French achievers, even when scores are adjusted for initial IQ and age differences. These findings are interpreted in the context of Cummins' (1976) “threshold” hypothesis relating to level of competence in the second language.     

Validity of psychologists' identification of EMR students in the perspective of the California decertification experience

The Diana (Diana v. State Board of Education, Note 1) and the Larry P. (Larry P. v. Riles, Note 2) litigations led to decertification of thousands of California EMR students and their return to the regular program. Allegations, including those of biased testing, went largely uncontested in order that change in special education could result from court mandate, but the allegations left the psychologists in a libeled state. A study of cumulative records and psychologists files in 12 representative districts permitted a comparison of the EMR placement of those later decertified (D) with matched nondecertified (EMR). Other than a small mean difference in IQ at placement, nothing was found to support various allegations. Records showed no systematic differences betweeen D and EMR groups in pre-EMR reasons for referral nor in teacher marks, discnfirming beliefs in referral of higher functioning students for deportment rather than for academic failure. Districts permitted a mean of at least two years in regular placement before assessment, attesting to class failure rather than IQ as the initial and necessary basis for EMR identification (no D-EMR difference in this either). The data permit a conclusion that the work of the school psychologists in the EMR placement was professionally competent, given the guidelines in effect at the time.     

Neuropsychological assessment of learning disabilities: a discriminant analysis

The neuropsychological test scores of 23 learning disabled children were compared with those of a matched population of normal children in the 9-1 to 13-1 age range. All children were administered the Wechsler Intelligence Scale for Children-Revised (WISC-R), a dichotic listening task involving both free and directed recall conditions, a handedness inventory, the Tactile Performance Test and the Category Test from the Halstead-Reitan Neuropsychological Test Battery. A multivariate analysis of variance resulted in a significant separation between groups (p less than .001) using these procedures. A stepwise discriminant function analysis revealed that both of the directed dichotic tasks contributed the most of all 13 measures to the significant group separation. In addition, other cognitive tasks found to discriminate normal from learning disabled children include general verbal processes, concept formation, and tactile memory. These findings suggest that the directed dichotic listening procedure and the WISC-R Verbal IQ measure are reasonably valuable clinical tools in the classification of learning disabilities.

Three-year analysis of characteristics of learning disabled students in self-contained classrooms and resource rooms

The present investigation examined the characteristics of school-identified learning disabled students from a large metropolitan school district in Tennessee. While it corroborated several findings of previous surveys of such students, this report also supplemented the literature by comparing the differences within a three-year span of time between school-identified learning disabled students who were assigned to self-contained classrooms and those who were assigned to resource rooms. Among the major findings were the presence of initial differences in IQ between self-contained and resource room students, the absence of differences in initial achievement scores between these two groups, and a decline over time in IQ, arithmetic, and spelling scores for both groups.     

Role-taking skills in intellectually-gifted third-grade children

Very bright (mean IQ = 152) third graders were compared with both average IQ third graders and average IQ sixth graders on perceptual, cognitive, and affective perspective-taking tasks. The role-taking skills of the intellectually-gifted children were more similar to those of their mental age mates than to those of their chronological age mates on both the cognitive and affective tasks. On the perceptual task, the bright children's performance fell between that of the two comparison groups. The results provide evidence that gifted children are advanced in thinking about both the social and physical worlds, and have implications for educational issues such as curriculum development and acceleration vs. enrichment.     

A Longitudinal Study of Exceptional Giftedness and Creativity

This article summarizes a longitudinal study of exceptionally gifted boys, with particular emphasis on ,findings involving their creative potential. The longitudinal investigation began 2 decades ago with 2 exceptionally gifted samples. These samples represented equivalent levels of ability but different areas or domains of talent. One was exceptionally gifted in math and science, the other a high-IQ group (mean IQ = 155). Data were collected from the boys and their parents. The present article summarizes group differences in expectations of independence, California Psychological Inventory (CPI; Gough, 1975) scales, and divergent thinking (DT) test scores. Relations among predictors are also discussed, as are relations with indexes of creative potential. In addition to group differences, notable findings include the strong relation between mothers' expectations for their sons' independence and the DT of the sons and the high flexibility scores of the exceptionally gifted samples on the CPI.     

Reading deficits and intellectual patterns among children with neurocognitive dysfunctions

Reading deficits among 56 elementary aged learning disabled children with suspected neurocognitive dysfunctions were calculated. The children were grouped according to the following IQ profiles: low Verbal-high Performance, high Verbal-low Performance, and a no-difference group. Differences in reading deficits among the groups were analyzed and the results indicate that the pattern of high Verbal-low Performance IQs is associated with the least deficiency in reading and that this association is evident as early as second grade within a group of learning disabled children with concomitant central processing problems.     

The use of imagery by intelligent and by creative schoolchildren

Two studies focusing on differences in thinking strategies between intellectually gifted and creative children were undertaken. In the first study (N = 29), ethnographic techniques of observation along with testing and problem-solving interviews were used in a regular classroom. Three subjects (one high IQ and high creativity, one high IQ and low creativity, and one low IQ and high creativity) were identified for intensive observation. In the second study, testing procedures and problem-solving interviews were completed with 30 children who were placed in a gifted program within an urban school system. Both studies produced evidence supporting the link between imaging abilities and creative thinking.     

Variations in WISC-R patterns of learning disabled children

The WISC-R was administered to 19 learning disabled students at the time of diagnosis and following a period of time in special program placements. Group analyses indicated fluctuations between testing times in the Verbal and Full-Scale IQs and the V-P IQ discrepancies. Small but significant differences in Verbal, Performance and V-P scatter indices were observed at one or both testings in comparison to the normal standardization sample. Although the suggested group pattern for learning disabled children based on the Bannatyne categories was confirmed on both occasions, there was considerable variation for individual subjects.     

A developmental perspective on reading dysfunction: Accuracy and rate criteria in the subtyping of dyslexic children

Children referred with specific reading dysfunction were subtyped as accuracy disabled or rate disabled according to criteria developed from an information processing model of reading skill. Multiple measures of oral and written language development were compared for two subtyped samples matched on age, sex, and IQ. The two samples were comparable in reading fluency, reading comprehension, word knowledge, and word retrieval functions. Accuracy disabled readers demonstrated inferior decoding and spelling skills. The accuracy disabled sample proved deficient in their understanding of oral language structure and in their ability to associate unfamiliar pseudowords and novel symbols in a task designed to simulate some of the learning involved in initial reading acquisition. It was suggested that these two samples of disabled readers may be best described with respect to their relative standing along a theoretical continuum of normal reading development.     

Television viewing habits of emotionally disturbed,learning disabled,and mentally retarded children

Two studies were conducted to compare the television viewing habits of handicapped and nonhandicapped children. In Study 1, one group (N = 38) of emotionally disturbed (ED), learning disabled (LD), and educable mentally retarded (EMR) children and two groups of matched controls comprised of nonhandicapped peers were interviewed about their television viewing habits. In Study 2, 42 ED boys and 42 non-ED boys completed a television program diary. The studies found that handicapped children watch more television overall and more aggression-laden programs (i.e., crime dramas and cartoons) than nonhandicapped children. The potential impact of viewing television aggression on the behavior of handicapped children is discussed.     

Reading-disabled hyperactive children: A distinct subgroup of Attention Deficit Disorder with Hyperactivity?

Mixed hyperactive/reading-disabled children, selected from a large sample of hyperactive children, were compared to pure hyperactive children on demographic, behavioral, and neuropsychological measures. Children in the Mixed group were reading-disabled relative to age and IQ; those in the Pure group had achievement scores that were average relative to age and IQ. The Mixed group was significantly older than the Pure group; there were no differences in gender, race, or socioeconomic status. Behaviorally, the groups did not differ significantly on teacher ratings or on psychiatric ratings of aggression. The Mixed group had a significantly higher Performance IQ, whereas the Pure group had a significantly higher Verbal IQ and performed better on measures of cognitive impulsivity. Several other measures failed to distinguish the groups. The data give minimal support to the notion that pure hyperactive and mixed hyperative/reading-disabled children constitute distinct subgroups of Attention Deficit Disorder with Hyperactivity.This research was supported in part by Mental Health Clinical Research Grant MH-30906 and by U. S. Public Health Service Grant MH-18579.     

Teachers' and mothers' academic achievement expectations for learning disabled children

The present study investigated teachers and mothers academic achievement expectations for learning disabled and normally achieving grade 3 children. Both groups had similar WISC-R mean Full Scale IQ scores, ages and socioeconomic backgrounds. It was found that teachers and mothers had significantly lower academic expectations for learning disabled children. The results are discussed in terms of the importance of positive affective development for learning disabled children and the need for more encouraging attitudes on the part of teachers and parents.     

Students Perception of Ability Scale: comparison of scores for gifted, average, and learning disabled students

On the Student's Perception of Ability Scale, comparison of scores for gifted, average, and learning disabled students differentiated the groups, thereby providing some construct validity as well as confirming the ceiling is high enough for use.
