Managing Complexity: Impact of Organization and Processing Style on Nonverbal Memory in Autism Spectrum Disorders / Katherine D. TSATSANIS in Journal of Autism and Developmental Disorders, 41-2 (February 2011)

The ROCF task involves a complex structure with strong organizational or integrative processing demands. The individuals with ASD relied on a predominantly part-oriented strategy to cope with the complexity of the task and did not make the typical developmental shift to a configurational approach. Both processing style and organization (whether pieces of information were perceived as connected to one another in a meaningful way) contributed to structural recall in the ASD group.

Patterns of Visual Attention to Faces and Objects in Autism Spectrum Disorder / James C. MCPARTLAND in Journal of Autism and Developmental Disorders, 41-2 (February 2011)

Point of gaze was recorded during passive viewing of images of human faces, inverted human faces, monkey faces, three-dimensional curvilinear objects, and two-dimensional geometric patterns. Individuals with ASD obtained lower scores on measures of face recognition and social-emotional functioning but exhibited similar patterns of visual attention. In individuals with ASD, face recognition performance was associated with social adaptive function. Results highlight heterogeneity in manifestation of social deficits in ASD and suggest that naturalistic assessments are important for quantifying atypicalities in visual attention.

Its relevance as a pathophysiological mechanism, however, remains unknown. In the present study, we compared eye fixations of 20 adults with autism and 21 controls while they were engaged in taking the Multifaceted Empathy Test (MET). Additional measures of face emotion and identity recognition were also obtained. While both groups fixated more on the face and mouth in the emotion recognition than in the face identity condition of the MET, individuals with autism fixated less on the face across MET conditions. Correlation analysis revealed associations between fixation time on the eyes and face processing abilities. Our results suggest that eye fixation patterns are an important characteristic of the social phenotype of autism.

We found that children with autism spectrum disorder (ASD), like typically developing children, can and do tell antisocial lies (to conceal a transgression) and white lies (in politeness settings). However, children with ASD were less able than typically developing children to cover up their initial lie; that is, children with ASD had difficulty exercising semantic leakage control—the ability to maintain consistency between their initial lie and subsequent statements. Furthermore, unlike in typically developing children, lie-telling ability in children with ASD was not found to be related to their false belief understanding. Future research should examine the underlying processes by which children with ASD tell lies.

How Temperament and Personality Contribute to the Maladjustment of Children With Autism / Sarah S.W. DE PAUW in Journal of Autism and Developmental Disorders, 41-2 (February 2011)

These classic spectrum hypothesis tests are extended by adding tests for similarity in variances, reliabilities and patterns of covariation between relevant variables. Children with ASD exhibit more extreme means, except for dominance. The low- and high-symptom ASD-groups are primarily differentiated by mean sociability and internal distress. Striking similarities in reliability and pattern of covariation of variables suggest that comparable processes link traits to maladaptation in low- and high-symptom children with ASD and in children with and without autism.

Contradictory research findings have challenged the meta-representational model. The intent of this paper is to propose that pretend play is the behavioral manifestation of developing imaginative ability, the complexity of which is determined by the degree of progression from part-object/inanimate object to whole-object/human object identification. We propose that autism is the result of non-completion of this process to varying degrees. This not only affects early pretend play behaviors, but also later social, language, and cognitive skills derived from the level of imagination-based sophistication achieved during foundational periods available for early identification.

Sensitivity was lower (0.60 [CI.95 = 0.45, 0.75]). Given diagnostic heterogeneity, and the broad array of ASD in the population, identifying children with ASD is challenging.

Increased Serum Levels of Epidermal Growth Factor in Children with Autism / Elvan ISERI in Journal of Autism and Developmental Disorders, 41-2 (February 2011)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 41-2 (February 2011) . - p.237-241 Titre : Increased Serum Levels of Epidermal Growth Factor in Children with Autism Type de document : Texte imprimé et/ou numérique Auteurs : Elvan ISERI, Auteur ; Esra GUNEY, Auteur ; Mehmet Fatih CEYLAN, Auteur ; Ayşegül YUCEL, Auteur ; Arzu ARAL, Auteur ; Sahin BODUR, Auteur ; Sahnur SENER, Auteur Année de publication : 2011 Article en page(s) : p.237-241 Langues : Anglais (eng) Mots-clés : Autism  Developmental disorders  Epidermal growth factor  Growth factors Index. décimale : PER Périodiques Résumé : The etiology of autism is unclear, however autism is considered as a multifactorial disorder that is influenced by neurological, environmental, immunological and genetic factors. Growth factors, including epidermal growth factor (EGF), play an important role in the celluler proliferation and the differentiation of the central and peripheral nervous system. In this study we hypothesized that EGF may play a role in the pathophysiology of autism and examined serum EGF levels in children with autism. We measured serum levels of EGF in the 27 autistic children and 28 age- matched normal controls. The serum levels of EGF in the subjects with autism were significantly higher than those of normal control subjects. However, there were no correlations between serum EGF levels and clinical variables in the subjects with autism. This is the first report demonstrating the increased serum levels of EGF in children with autism. This study suggests that increased levels of EGF might have an importance in the pathophysiology of autism.

Brief Report: Circumscribed Attention in Young Children with Autism / Noah J. SASSON in Journal of Autism and Developmental Disorders, 41-2 (February 2011)

The current study downward extended these findings to a sample of 2–5 year-olds with autism and 2–5 year-old typically developing children. Eye-tracking was used to quantify discrete aspects of visual attention to picture arrays containing combinations of social pictures, pictures of objects frequently involved in circumscribed interests in persons with autism (e.g., trains), and pictures of more commonplace objects (e.g., clothing). The children with autism exhibited greater exploration and perseverative attention on objects related to circumscribed interests than did typically developing children. Results suggest that circumscribed attention may be an early emerging characteristic of autism.

Brief Report: Sensorimotor Gating in Idiopathic Autism and Autism Associated with Fragile X Syndrome / Jennifer YUHAS in Journal of Autism and Developmental Disorders, 41-2 (February 2011)

We compared PPI in four groups: typically developing controls (n = 18), FXS and autism (FXS+A; n = 15), FXS without autism spectrum disorder (FXS−A; n = 17), and idiopathic autism (IA; n = 15). Relative to controls, the FXS+A (p < 0.002) and FXS−A (p < 0.003) groups had impaired PPI. The FXS+A (p < 0.01) and FXS−A (p < 0.03) groups had lower PPI than the IA group. Prolonged startle latency was seen in the IA group. The differing PPI profiles seen in the FXS+A and IA indicates these groups may not share a common neurobiological abnormality of sensorimotor gating.
