Social Competence in Children with Learning and Autism Spectrum Disorders
Objective: The present study has been carried out to compare the social competence in two groups of students with Autism Disorder (AD) and Learning Disorders (LD). Methods: This research was a kind of descriptive research with 2 comparative groups. 90 learning and Autistic disorder students aged 10 to 13 years (45 LD & 45 AD) were selected randomly as a statistical sample. For the assessment...
متن کاملAtypical modulation of distant functional connectivity by cognitive state in children with Autism Spectrum Disorders
We examined whether modulation of functional connectivity by cognitive state differed between pre-adolescent children with Autism Spectrum Disorders (ASD) and age and IQ-matched control children. Children underwent functional magnetic resonance imaging (fMRI) during two states, a resting state followed by a sustained attention task. A voxel-wise method was used to characterize functional connec...
متن کاملResting-State Functional Connectivity in Autism Spectrum Disorders: A Review
Ongoing debate exists within the resting-state functional MRI (fMRI) literature over how intrinsic connectivity is altered in the autistic brain, with reports of general over-connectivity, under-connectivity, and/or a combination of both. Classifying autism using brain connectivity is complicated by the heterogeneous nature of the condition, allowing for the possibility of widely variable conne...
متن کاملAtypical functional brain connectivity during rest in autism spectrum disorders.
OBJECTIVE Connectivity atypicalities in autism spectrum disorders (ASD) have been extensively proposed. The default mode network (DMN) is critical in this study, given the insight it provides for long-distance connectivity, and the importance of regions in this network for introspection and social emotion processing, areas affected in ASD. However, study of this network has largely been limited...
متن کاملAbnormalities of intrinsic functional connectivity in autism spectrum disorders,
Autism spectrum disorders (ASD) impact social functioning and communication, and individuals with these disorders often have restrictive and repetitive behaviors. Accumulating data indicate that ASD is associated with alterations of neural circuitry. Functional MRI (FMRI) studies have focused on connectivity in the context of psychological tasks. However, even in the absence of a task, the brai...
