Item Internalized socioemotional functioning of children and adolescents with nonverbal learning disability and Asperger's syndrome(2007) Gerrard-Morris, Aimée Elizabeth, 1977-; Semrud-Clikeman, Margaret; Keith, Timothy, 1952-Visual-spatial skills deficits are one of the primary neuropsychological deficits among children with Nonverbal Learning Disability (NVLD; Rourke, 1989) and Asperger's Syndrome (AS; Ellis, & Gunter, 1999; Klin, Volkmar, Sparrow, Cicchetti, & Rourke, 1995). In addition to affecting written tasks, visual-spatial deficits also have implications for the social functioning of children. Children who are not able to accurately process visual-spatial information will have difficulty processing the visual, nonverbal cues present in social situations including facial expressions, hand movements, and body posture (Nowicki & Duke, 1992). These social perception deficits make social interactions difficult for these children. As a result of their social differences, they are likely to get negative reactions from others, have social skills deficits (Petti, Voelker, Shore, and Hayman-Abello, 2003), and have much difficulty fitting in with same-aged peers. These social skills deficits will likely lead to internalized adjustment problems in which these children feel isolated, withdrawn, and depressed around their peers. This sequence of events, visual-spatial deficits, followed by social perception deficits, followed by social skills deficits, which ultimately lead to internalized emotional problems, is implied, but not empirically proven, in a study by Petti and colleagues (2003). In addition to experiencing greater socioemotional problems than other LD subtypes, visual-spatial and social deficits of children with NVLD have been shown to worsen with age (Casey, Rourke and Picard, 1991). This dissertation study investigated the relation between these four constructs (i.e., visual-spatial skills, social perception, social skills, and internalized emotional functioning). It was hypothesized that social perception and social skills mediate the relationship between visual-spatial skills and internalized emotional functioning. In addition, these deficits were expected to increase as these children get older. As NVLD and AS are commonly co-morbid with Attention Deficit/Hyperactivity DisorderPredominantly Inattentive Type (ADHD: PI; Gross-Tsur & Shalev, 1995; Voeller, 1996), this diagnostic group was compared to children diagnosed with ADHD: PI. An additional aim of this study was to differentiate the classification of Learning Disability (LD) by demonstrating the socioemotional functioning differences between individuals with NVLD/ADHD: PI and their counterparts -- individuals with a Verbal Learning Disability (VLD/ADHD: PI). Seventy-one children, ranging in age from 8-14 participated in the study and were assigned to one of three groups (e.g., NVLD/AS with ADHD: PI, VLD with ADHD: PI, or ADHD: PI) based on pre-determined criteria. The NVLD/AS group, as expected, showed impairments in all areas (i.e., visual-spatial skills, social perception, social skills, and internalized socioemotional functioning) and significantly differed from one or both of the other groups on each of the four domains. Support was not found for the age effects for the NVLD/AS group. That is, visual-spatial and internalized socioemotional scores did not worsen with increasing age as expected. Also, visual-spatial skills were not significantly related to internalizing socioemotional functioning, and the hypothesized mediation variables were not statistically significant. The current study contributes to the understanding of individuals with NVLD, an under-studied population. The proposed visual-spatial skills deficits and social perception deficits in Rourke's (1989) theoretical model were supported. This study also offers some insight into the internalizing socioemotional functioning of children with NVLD. It clarifies the heterogeneity of socioemotional functioning among LD children, suggesting that it is children with the LD subtype, namely NVLD, who are at greater risk for social problems.Item Relational functioning in the family systems of children with social competency disorders(2008-08) Kruschwitz, Moana Gayle, 1973-; Carlson, Cindy I., 1949-; Semrud-Clikeman, MargaretDespite a remarkable need and demand for services, little is known about the family relationships of children with social competency disorders (SCD), defined in this study as children with Asperger’s Disorder and nonverbal learning disabilities (NVLD). Both children with Asperger’s Disorder and children with NVLD exhibit social skill deficits essential to building and maintaining relationships. These social competency impairments are thought to be related to similarities in their neuropsychological profiles. The low prevalence rates of these conditions and the neuropsychological and behavioral similarities supports the combination of Asperger’s Disorder and NVLD as a “social competency disorders” group for purposes of research. Attention deficit-hyperactivity disorders (ADHD) have been found to be highly comorbid in children with SCD, and were included in this study as clinical control group. The purpose of this study was to examine the relational functioning in the families of children with social competency deficits across different parts of the family system. It was hypothesized that the social competency deficits in children with SCD would result in significantly lower levels of relational functioning across the parent-child subsystem, parenting subsystem and whole family level of the family. Sixty-one children between the ages of 8-12 and their mothers participated in this study. Children were assigned to the SCD, ADHD or typically developing group based on pre-determined criteria. Self-report measures of interpersonal functioning in the parent-child relationship, strength of parenting alliance in the parental relationship and social support in the whole family were collected and compared across the three groups. As predicted, mothers of children with SCD reported significantly higher levels of dysfunction in the parent-child subsystem as compared to mothers of typically developing children; however, no significant differences in parent-child dysfunction were found between the SCD and the ADHD group. Contrary to the hypotheses proposed in this study, the SCD group showed no significant group differences on measures of parenting alliance and social support in the whole family. This study reveals the importance of intervention in the parent-child relationship in these families, and the need for additional research using longitudinal, multi-modal and multiple informant designs.
