Event and story structure recall by children with specific learning disabilities,language impairments,and normally achieving children

This study investigated the ability of children with specific learning disabilities (SLD), children with language impairments (LI), and children who are normally achieving (NA) to recall the events and story structures of a narrative and an expository text. Effects of group, verbal age, text structure, and order of presentation on recall as measured through listening comprehension were studied. Sixty students who were matched on verbal age served as subjects. Results suggested differences between the LI and SLD groups on text recall. Differences were also evident for text type, with recall of narrative text typically being superior to recall of expository text. In general, the performance of the group with SLD was similar to that of the NA group.     

Naming of object-drawings by dyslexic and other learning disabled children

On the Oldfield-Wingfield Picture-Naming Test, sensitive to subtle chronic dysphasia in adults, dyslexic children name fewer pictures correctly. Even when correct on words with less than 30 per million frequency of occurrence, they perform more slowly than do nondyslexic subjects suffering from minimal brain dysfunction (MBD) or normal controls. However, there is no evidence for “perceptual impairment” underlying dyslexic subjects' low scores and prolonged latencies, as the distribution of their errors is similar to that of normal children. Rather it is the nondyslexic MBD group which produces a high percentage of wrong names, suggestive of mistaking the pictured stimuli for other, visually similar, objects.     

Behaviors and attitudes of normally developing children toward their intellectually disabled siblings

This study investigated behaviors of children who have normal development toward their siblings with intellectual disabilities. 9- to 17-year-old normally developing siblings (55 girls, 39 boys) of 94, 5- to 15-year-old mentally disabled children (51 girls, 43 boys) who were attending a special education and rehabilitation center were enrolled in the study. Data were gathered by using a general information form and the Schaeffer Sibling Behavior Rating Scale. Age of the disabled child did not have a significant effect on siblings' behaviors, while knowledge of family about the diagnosis and educational status of their child with intellectual disabilities affected sibling behaviors.     

Tactile discrimination, response mode, and interhemispheric communication by learning disabled children.

32 right-handed, learning disabled children aged 8-10 yr., 11-13 yr., and 14-16 yr. were presented a tactile discrimination task. Pairs of fabrics of different or the same texture were presented to the same hand (uncrossed condition) or alternating hands (crossed condition). Discrimination errors were compared using a verbal response mode and a nonverbal response mode. Analysis indicated that the number of crossed errors was significantly greater in the verbal response mode than in the nonverbal response mode for only the youngest children. These results suggest selective attention-activation bias and/or hemispheric processing limitations for younger learning disabled children.     

The role of verbal behavior in human learning: III. Instructional effects in children

Lever pressing of children from three age groups (2½ to 4, 5 to 6½, and 7½ to 9 years) could produce reinforcers according to a fixed-interval 40-s schedule: (1) Some were instructed to respond at a high rate, others at a low rate, and (2) they were subsequently taught to provide their own spoken self-instructions consonant with the earlier, experimenter-supplied instructions. All subjects who received high-rate instructions responded at a steady, high rate, which was maintained following self-instructional training. The effects of low-rate instructions were directly related to the age of the children. The two older groups produced low-rate patterns, with the oldest children responding at very low rates; effects were least noticeable in the youngest age group. Following self-instructional training, all three groups showed adult-like low-rate behavior and the oldest children showed an improved ability to estimate the interval length. The results provide further evidence of the importance of language as a determinant of human behavior.     

Dynamic balance of learning disabled and nondisabled children

This investigation assessed a difference in the dynamic balance abilities of 30 learning disabled and 30 nondisabled children of elementary-school age. Only distance traveled across the beam, a novel task, was significantly different between groups; no other effects were significant. Nondisabled subjects traveled further across the beam before losing balance than learning disabled children.     

Vision and academic performance of learning disabled children

The purpose of this study was to assess difference in academic performance among myopic, hyperopic, and emmetropic children who were learning disabled. More specifically, myopic children were expected to perform better on mathematical and spatial tasks than would hyperopic ones and that hyperopic and emmetropic children would perform better on verbal measures than would myopic ones. For 439 learning disabled students visual anomalies were determined via a Generated Retinal Reflex Image Screening System. Test data were obtained from school files. Partial support for the hypothesis was obtained. Myopic learning disabled children outperformed hyperopic and emmetropic children on the Key Math test. Myopic children scored better than hyperopic children on the WRAT Reading subtest and on the Durrell Analysis of Reading Difficulty Oral Reading Comprehension, Oral Rate, Flashword, and Spelling subtests, and on the Key Math Measurement and Total Scores. Severity of refractive error significantly affected the Wechsler Intelligence Scale for Children--Revised Full Scale, Performance Scale, Verbal Scale, and Digit Span scores but did not affect any academic test scores. Several other findings were also reported. Those with nonametropic problems scored higher than those without problems on the Key Math Time subtest. Implications supportive of the theories of Benbow and Benbow and Geschwind and Behan were stated.     

The effects of cognitive-behavior modification on private speech and task performance during problem solving among learning-disabled and normally achieving children

Recent research has supported the hypothesis that poor performance among learning-disabled (LD) children is frequently the result of deficits in self-regulation of strategic behaviors, rather than structural or ability deficits. As a result, cognitive-behavior modification (CBM) techniques that emphasize development of self-regulation through self-verbalizations (private speech) have been strongly recommended. The present study examined the natural occurrence of regulatory private speech among LD and normally achieving children during problem solving, as well as the effects of CBM training on private speech and task performance. Results indicated significant deficiencies in private speech and task performance among LD children; CBM training resulted in significant improvements. These results provide further verification of deficits in self-regulation of cognitive activity among LD children and import implications for intervention.The author would like to thank Gerald Halpin, Glennelle Halpin, and Ronhie Wilbur for their assistance throughout this study.     

Psychoeducation and expressed emotion by parents of children with learning disorders

The present study assessed use of a psychoeducation group program on expressed emotion, family functioning, and child behavior by parents of children with learning disorders. 81 parents of children with learning disorders were randomly assigned to a psychoeducation group program (n=46) or to a regular treatment group (n=35). A semistructured interview for parental expressed emotion, self-reports of family functioning, and child behavior were utilized at baseline and after an 8-session psychoeducation group program. Parents who attended the program differed significantly from parents in the regular treatment group on measures of criticism, warmth, and positive remarks, and overall expressed emotion, but not on measures of perceived family functioning and child behavior. Findings indicate a psychoeducation group program could be effective in helping parents to establish a more positive emotional climate in their relationships with their children who have learning disorders.     

Factorially defined verbal and performance IQs derived from the WISC-R: Patterns of cognitive ability in normal and learning disabled children

The axes of the first two dimensions of a principal components analysis of the normative data of the WISC-R were rotated through 45°. This resulted in two orthogonal continua which were interpreted as describing verbal and nonverbal intelligence respectively. Factor score coefficients were used to calculate Verbal Factorial IQs (VFIQs) and Performance Factorial IQs (PFIQs). In normal children, girls (N=1100) prove to be reliably superior to boys (N=1099) in VFIQ, whereas the reverse is the case for PFIQ. In a large group (N=1050) of learning disabled (LD) children, VFIQ is reliably lower than in normal children, and there is also a reliable decline with age over the years 6–16. The LD boys (N=744) are no different from the LD girls (N=306) in VFIQ. In these LD groups the PFIQ is reliably lower than in the normal group at age 6, but rises to a normal level by age 8. The LD boys, overall, return higher PFIQ scores than the LD girls. These results can be used to evaluate the rival hypotheses of ‘deficit’ vs ‘developmental lag’ as a cause of learning disability.     

Components of verbal learning in children: Analysis by selective reminding

Free recall verbal learning by 5- and 8-year-old children was analyzed by selectively reminding them only of items not recalled on the preceding trial (instead of continuing to present the entire list before each recall trial) to show learning by retrieval from long-term storage without presentation. Concurrent analysis of long-term storage, consistent and random retrieval from long-term storage, and recall from short-term storage indicates that, while 5-year-olds showed slower acquisition than 8-year-olds, lower recall by 5-year-olds also was due to less effective retrieval from longterm storage. Repeated retrieval, without any further presentation after an item has been recalled just once, indicates that lower recall by 9-year-old children than by adults also reflects retrieval difficulty, since these children showed storage and retention of almost as many items as adults by eventual spontaneous retrieval without further presentation.     

Verbal and affective laterality effects in P-dyslexic, L-dyslexic and normal children.

Lateralization of verbal and affective processes was investigated in P-dyslexic, L-dyslexic and normal children with the aid of a dichotic listening task. The children were asked to detect either the presence of a specific target word or of words spoken in a specific emotional tone of voice. The number of correct responses and reaction time were recorded. For monitoring words, an overall right ear advantage was obtained. However, further tests showed no significant ear advantage for P-types, and a right ear advantage for L-types and controls. For emotions, an overall left ear advantage was obtained that was less robust than the word-effect. The results of the word task are in support of previous findings concerning differences between P- and L-dyslexics in verbal processing according to the balance model of dyslexia. However, dyslexic children do not differ from controls on processing of emotional prosody although certain task variables may have affected this result.     

Tactile stimulation and interhemispheric communication by learning disabled children: an exploratory study

33 right-handed, learning disabled children aged 8-10 yr., 11-13 yr., and 14-16 yr. were presented a tactile discrimination task. Pairs of fabrics of different or the same texture were presented to the same hand (uncrossed condition) or alternating hands (crossed condition). Analysis indicated that the total number of crossed errors was significantly greater for the youngest children. There were no significant differences between the groups for the uncrossed condition. These results suggest that younger learning disabled children may experience greater difficulty on a task which required interhemispheric transfer.     

Hyperactivity and related behavioral characteristics in a sample of learning disabled children.

64 learning disabled and 12 minimal brain-damaged children were evaluated by their teachers on 11 categories of behavior. Analysis showed that behavioral characteristics associated with hyperactivity did not differentiate among subjects. Teachers rated poor motor coordination as the outstanding trait of this sample.     

Motor and cognitive proficiency of learning disabled and normal children

Motor and cognitive skills of learning disabled (N = 32) and normal (N = 32) boys were compared on the Modified Lincoln-Oseretsky Motor Development Scale and on the WISC-R Vocabulary and Block Design subtests. Eight learning disabled and eight normal boys were tested at four age levels from 8 to 11 years. All boys were of normal intelligence. Motor and cognitive skills of the learning disabled boys were significantly below those of the normal boys and below those of the normative group. Chronological age was not a significant factor in relationship to either motor or cognitive skills. Intercorrelations indicated that in the learning disabled group Block Design, but not Vocabulary, was significantly related to motor scores at the 8- and 9-year ages. These results suggest that a common factor relating to perceptual-motor coordination and efficiency may be involved on the Lincoln-Oseretsky and Block Design subtest for young learning disabled children but not for older learning disabled children or for normal children.
