Comprehension of humor in children with nonverbal learning disabilities,reading disabilities,and without learning disabilities

The normal development of humor in children has been well documented with a predictable course that is tied to social, cognitive, and linguistic development in children. This study explored humor comprehension in children with nonverbal learning disabilities (NVLD). Children with NVLD were compared with children with reading disabilities and a comparison group of children with no learning disabilities to assess their comprehension of humor. The humor test was composed of a joke and cartoon section. No group differences in humor comprehension were found when the NVLD group was defined as having visual–spatial and visual reasoning deficits. However, when the NVLD group was divided into children with and without social perceptual difficulties as defined by a direct measure of social comprehension, significant group differences were found in the levels of humor comprehension. These results support the association of humor comprehension with social perception and lend tentative support to the hypothesis that children with NVLD may not be a homogenous group. Future study directions include further exploration into the nature of the association between humor comprehension and social perception as well as closer examination of the heterogeneity of NVLD.     

Cognitive correlates of social perception in students with learning disabilities

In investigating possible explanations for social skills deficits in students with learning disabilities, researchers have examined social perception-the interpretation of behavior in order to understand the thoughts and feelings of others. This study specifically examined cognitive correlates of social perception in individuals with learning disabilities. Thirty-two students with learning disabilities in elementary grades were measured on three subtests (Comprehension, Picture Arrangement, and Digit Span) of the Wechsler Intelligence Scale for Children-Revised and on the Profile of Nonverbal Sensitivity. Both Picture Arrangement and Comprehension seemed to have an inherent relation to social perceptual functioning. Implications of these results are discussed.     

Relationship between social perception and peer status in children with learning disabilities

This study was undertaken to examine the social perceptual skill deficit theory in explaining the low peer acceptance of children with learning disabilities. The quality of tests measuring social perception was also examined. Thirty 9- to 12-year-old children with learning disabilities and a matched control group were given two measures of social perception: a laboratory task and a behavior rating scale. The behavior rating scale was completed by the children's teachers. In addition, the Peer Acceptance Scale (Bruininks, Rynders, & Gross, 1974) was administered to assess peer status. Results showed that the children with learning disabilities differed significantly from their nondisabled peers on each of the three measures-the children with learning disabilities obtained lower social perception and peer acceptance scores. However, the relationships between sociometric status and social perception varied as a function of task. A small but significant correlation wa found between the behavior rating scale and peer status. The laboratory task was not correlated with either the behavior rating scale or peer status. Results are discussed in terms of the psychometric properties of laboratory versus naturalistic measures of social perception and the importance of establishing the external validity of social skill measures by correlating them with outcome measures such as peer status.     

Imagery deficits in nonverbal learning disabilities

This study reports the observations gathered from 11 children referred to consulting services because of learning difficulties at school and diagnosed with nonverbal learning disabilities (NVLD). These children had an average verbal IQ, but a WISC-R performance IQ lower than the verbal IQ by at least 15 points and experienced difficulties especially in mathematics and drawing. The children completed a battery of four tasks requiring visuospatial working memory and visual imagery: a memory task composed of pictures and their positions (Pictures task), a task that required them to memorize the positions filled in a matrix (Passive Matrix task), a task that required them to imagine a pathway along a matrix (Active Matrix task) and a task that required them to learn groups made up of three words, using a visual interactive imagery strategy (TV task). In comparison to a control group of 49 children, children with NVLD scored lower in all the tasks, showing deficits in the use of visuospatial working memory and visual imagery. By contrasting subgroups of children of different ages in the control group, it was possible to show that some tasks did not show a clear developmental trend. Thus the deficits shown by the children with NVLD cannot simply be attributed to a developmental delay of these children, but seem to reflect a more severe disability.     

Perceived importance of occupations by adolescents with and without learning disabilities

A study of the perceived importance of 23 occupations by 65 adolescents with learning disabilities and 85 adolescents without learning disabilities revealed that occupations were ranked similarly by the two groups (Rho = .76). Analysis of the groups' rank order indicated diversity of students' perceptions about the importance of various occupations.     

Visual processing of verbal and nonverbal stimuli in adolescents with reading disabilities

This study investigated whether a group of children with reading disabilities (RD) were slower at processing visual information in general (compared to a group of children of comparable age and a group of children of comparable reading level), or whether their deficit was specific to the written word. Computerized backward masking and temporal integration tasks were used to assess the speed of visual information processing. Stimulus complexity (simple, complex) and type (verbal, nonverbal) were varied, creating a 2 x 2 matrix of stimulus conditions: simple nonverbal, complex nonverbal, simple verbal, and complex verbal. Adolescents with RD demonstrated difficulties in processing rapidly presented verbal and nonverbal visual stimuli, although the effect was magnified when they were processing verbal stimuli. Thus, the results of this study suggest that some youth with reading disabilities have visual temporal processing deficits that compound difficulties in processing verbal information during reading.     

Vowel perception and production in adolescents with reading disabilities

Perception and production of the vowels /I/, /?/, /æ/ in the words pit, pet and pat were investigated in two groups of adolescents who differed significantly on measures of reading and phonological awareness. Perception performance was assessed using slope measurements between vowel categories. Duration measurements and a rating system based on first and second formant (F1 and F2) values were used to analyze production performance. As a group, the students with reading disabilities not only perceived but also produced less well-defined vowel categories than the control group of age-matched good readers. Perception and production performance, however, were not correlated. Results suggest that the speech processing difficulties of the students with reading disabilities include weak phonological coding for vowel sounds with similar phonetic characteristics. The implications of these findings for intervention are addressed.     

Verbal retelling abilities in adolescents with and without language-learning disabilities for social studies lectures

Verbal retelling abilities for social studies lectures were examined and compared in 20 adolescent boys, ages 12-5 to 14-7, with language-learning disabilities (LLD) and 29 with normal language abilities (NL). Participants viewed one videotaped social studies lecture with a comparison expository discourse structure and one with a causation discourse structure. Following each lecture presentation, participants verbally retold the lecture. Results of several repeated-measures analyses of variance indicated that the group with LLD produced a significantly smaller number of T-units, subordinate clauses, subordinate clauses per T-unit, T-units per second, lecture components per second, and percentage of lecture components in their retellings, compared with the group with NL, regardless of lecture type. Both groups produced a significantly greater number of T-units and subordinate clauses for the comparison lecture. By contrast, both groups recalled a significantly greater number of lecture components per T-unit and per second for the causation lecture. Results indicated that the comparison discourse structure facilitated more substantive and elaborate retellings, whereas the causation discourse structure facilitated more efficient, concise retellings in both groups. Research and instructional implications are discussed.     

Peer groups, popularity, and social preference: trajectories of social functioning among students with and without learning disabilities

The extant literature on the social functioning of students with learning disabilities (LD) has indicated that whereas a majority belong to peer groups, a higher proportion are isolated and most have lower social status among peers in general than their typically achieving classmates. Although some work has examined these issues over short-term longitudinal studies, none to date have examined them over extensive time periods. Toward this end, the current study examined a sample of 1,361 students (678 girls and 683 boys; 55 with LD) using multiple measures of peer social functioning assessed each semester from spring of third grade through fall of sixth grade. The results indicated that whereas students with LD were similar to their typically achieving peers in terms of group functioning and characteristics, they were viewed as lower in social standing among their classmates as a whole. These effects were maintained over time, indicating that long-term inclusion may not substantially affect peer social functioning among students with LD.     

Using predictions to learn about the self-efficacy of early adolescents with and without learning disabilities

This study used conventional self-efficacy measures as well as predictions of performance to examine the spelling and writing efficacy beliefs of early adolescents with and without learning disabilities (LD). In addition, the study examined two types of global efficacy—self-efficacy for self-regulated learning and general self-efficacy. The students with LD over-estimated their spelling performance by 52% and their writing performance by 19%, whereas the non-LD students were generally accurate in their performance estimates. Students’ performance predictions and self-efficacy ratings were strong predictors of a composite writing performance, but the self-efficacy for self-regulated learning and general self-efficacy scores did not predict writing performance. The article concludes with a discussion of recommendations to improve the calibration and academic functioning of adolescents with learning disabilities.     

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.     

Predicting performance on academic and non-academic tasks: A comparison of adolescents with and without learning disabilities

Previous research suggests that adolescents with learning disabilities (LD) are less accurate in predicting academic performance than normally achieving (NA) adolescents and display a tendency to overestimate their level of performance (e.g., Klassen, 2007). However, no studies have been conducted investigating whether this overestimation is specific to academic contexts or a phenomenon that extends across domains. Ninety-four adolescents (46 LD, 48 NA) predicted their performance on a spelling task and on a ball-throwing task. Results revealed group differences in performance calibration across domains with adolescents with LD showing an overestimation of ability on the spelling and ball-throwing tasks, and NA adolescents demonstrating more precise self-appraisals. Additionally, the accuracy of non-academic performance predictions remained stable with increasing difficulty in the NA group whereas the adolescents with LD demonstrated a decrease in accurate performance prediction as the difficulty level increased.     

WISC-III profiles for children with and without learning disabilities

The degree of WISC-III intersubtest scatter was normal and similar for 66 children with LD and 51 children without LD, but the pattern of scores differed. In the 8- to 16-year-old sample, children with LD scored lower on the Freedom from Distractibility Index relative to FSIQ than children without LD. This difference was found in both the ADHD and nonADHD subgroups, suggesting that children with LD may have an attention deficit even if they do not meet the diagnostic criteria for ADHD. The CAD profile was evident in the mean scores for both the LD/ADHD and LD/nonADHD subgroups, but it was not found among the lowest subtest scores for any of the nonLD subgroups. Though WISC-III profile types were apparent in LD group data, only a minority of individual children with LD actually had these profiles. In the 6- and 7-year-old group, children with and without LD were indistinguishable on the WISC-III, which may reflect the difficulty of ruling out LD at this young age. © 1998 John Wiley & Sons, Inc.     

The accuracy of academic self-evaluations in adolescents with learning disabilities

The purpose of this study was to document the degree of overestimation of academic skills among students with learning disabilities (LD) and to evaluate the role of reference group and metacognitive awareness in such overestimation. High school students with (n = 52) and without (n = 49) LD in Grades 9 through 12 completed a self-concept scale and a survey requiring them to rate their own academic skills in 17 specific skill areas. Students were further asked to predict their performance on two academic tasks prior to actually performing the tasks. The students' mothers or fathers, their English teachers or academic advisors, and (in the case of the students with LD) their special education case managers also completed the skill rating inventory and predicted student performance on the two tests. Despite reporting significantly lower academic self-concepts, students with LD overestimated their academic skills relative to the ratings of others and to their actual test performance. Such overestimation was less pronounced among the students without LD. All participants reported using similar reference groups in making their judgments. Analyses of item-by-item accuracy judgments from the two tests revealed evidence of group differences in metacognitive awareness that may be related to the overestimation. These findings have implications for realistic goal setting and effective self-advocacy.     

Frequency of adoption of children and adolescents with learning disabilities

Students from three different facilities who were diagnosed as learning disabled were studied to determine the frequency of adoption with this population as compared to the national norm. The frequency of adoption was found to be 4.5 times higher than the norm, that is, 17.3% versus 3.9%. The possible reasons for this high incidence are discussed.
