Auditory, visual, and multisensory nonverbal social perception in adolescents with and without learning disabilities

Adolescents with and without learning disabilities (14, 16, and 18 years old) were tested to determine whether they differed in auditory, visual, and/or multisensory (combined auditory/visual) social perception abilities. Differences between the two groups in growth of auditory, visual, and multisensory social-perception abilities were also measured. Results of the data analyses revealed that adolescents with learning disabilities were not as adept at understanding nonverbal social information regardless of whether the information was visual or multisensory in nature. Further, nonverbal social-perception ability for both visual and multisensory information improved with increasing age for both populations. Finally, adolescents with learning disabilities continued to demonstrate comparatively poorer social-perception abilities through the 18-year level.     

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.     

Sex differences in learning abilities and disabilities

Boys more often than girls are affected by all the cognitive developmental disorders of childhood. Differences in the etiology of learning disabilities as well as general sex differences in learning styles in boys versus girls may explain the male preponderance in the prevalence of learning disabilities. The effects on learning of hormonal sex differences, maturation rate differences, and differences in frequency of perinatal brain injury will be discussed.     

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.     

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.     

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.     

A word identification strategy for adolescents with learning disabilities

Students with learning disabilities frequently experience difficulty on reading tasks. This difficulty is heightened for adolescents with learning disabilities who are responsible for reading and understanding materials written at several grade levels above their reading ability. Word identification becomes an increasingly important skill for these students, especially when confronted with unfamiliar, polysyllabic words. The present study investigated the effects of training 12 adolescents with learning disabilities in a word identification strategy, DISSECT. The results indicated that the strategy was effective in reducing reading errors for all subjects. However, it was found that increases in word identification differentially affected reading comprehension and indicate the need for separate and/or simultaneous attention to comprehension processes.     

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.     

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.     

Language abilities and progress in a direct instruction reading program for students with learning disabilities

Direct instruction reading programs have been found to be a successful way to teach reading to many, but not all, students with learning disabilities. This study investigated whether reading improvement for students with learning disabilities receiving reading instruction through a direct instruction reading program might be related to their language abilities. The reading progress of 26 students (19 male, 7 female), 7 to 10 years old, was measured over 2 years. In addition, phonological and syntactic abilities were assessed. The results indicated that phonological ability was related to progress in word attack skills and that syntactic ability was related to improvement in comprehension skills. These results have implications for the reading instruction of students with learning disabilities.     

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.     

Learning disabilities and risk-taking behavior in adolescents: a comparison of those with and without comorbid attention-deficit/hyperactivity disorder

Risk-taking behavior includes alcohol and drug use, delinquency, acts of aggression, sexual activity, and so on. Many studies have explored the relationship between adolescents and risk-taking behavior; however, only a few studies have examined this link in adolescents with learning disabilities (LD) or attention-deficit/hyperactivity disorder (ADHD). The purpose of the present study was to address that limitation by comparing the risk-taking behavior of adolescents with LD (n=230), with comorbid LD/ADHD (n=92), and without LD or ADHD (n=322) on their substance use, engagement in major and minor delinquency, acts of aggression, sexual activity, and gambling activities. The study also investigated whether psychosocial variables (e.g., well-being) may act as mediating variables that help explain between-group differences. Results suggest that it is a combination of the LD and the secondary psychosocial characteristics that explains why adolescents with LD and comorbid LD/ADHD more frequently engage in some risk-taking behavior.     

Mathematical problem-solving profiles of students with mathematics disabilities with and without comorbid reading disabilities

The purpose of this study was to describe the mathematical problem-solving profiles of students with mathematics disabilities (MD) with and without comorbid reading disabilities (RD). The disability status of fourth-grade students was verified through testing (n = 18 MD; n = 22 MD + RD). Then a hierarchy of mathematics problem-solving tasks was administered. The results demonstrated large deficits for both groups; however, the differences between students with MD and those with MD + RD were mediated by the level of problem solving (arithmetic story problems vs. complex story problems vs. real-world problem solving) and by performance dimension (operations vs. problem solving). On arithmetic story problems, the differences between the disability subtypes were similar for operations and problem solving. By contrast, on complex story problems and real-world problem solving, the differences between the subtypes were larger for problem solving than for operations.     

A review of social interventions for students with learning disabilities

Twenty-two studies are reviewed that report the effects of social skills training and intervention with 572 children identified as learning disabled between 5 and 19 years of age. These studies are reviewed to examine characteristics and components of intervention effectiveness. Age and sex of subjects, grade grouping, group size, intervention duration, intervention procedures, subject selection, and type of interventional model are examined to find patterns that reflect intervention success. Several intervention characteristics and components are associated with social intervention effectiveness: selecting subjects who had social skills difficulties or low peer acceptance, using cognitive-behavioral intervention procedures, providing individual or small group instruction, and applying long-term intervention and training. Discussion focuses on difficulties in comparing studies to determine intervention effectiveness through the examination of outcome measures, a call for revisions in future reporting of social interventions in the literature, and those intervention factors that relate to increases in peer acceptance.
