Direct linkVan der Hallen, Ruth; Chamberlain, Rebecca; de-Wit, Lee; Wagemans, Johan – Journal of Autism and Developmental Disorders, 2018
Since its initial development, the embedded figures test (EFT) has been used extensively to measure local-global perceptual style. However, little is known about the perceptual factors that influence target detection. The current study aimed to investigate "disembedding" in children with and without ASD, aged 8-15 years, using the newly…

Booth, Rhonda D. L.; Happé, Francesca G. E. – Journal of Autism and Developmental Disorders, 2018
Frith's original notion of 'weak central coherence' suggested that increased local processing in autism spectrum disorder (ASD) resulted from reduced global processing. More recent accounts have emphasised superior local perception and suggested intact global integration. However, tasks often place local and global processing in direct trade-off,…

Donaldson, Chelsea K.; Stauder, Johannes E. A.; Donkers, Franc C. L. – Journal of Autism and Developmental Disorders, 2017
Recent studies have suggested that sensory processing atypicalities may share genetic influences with autism spectrum disorder (ASD). To further investigate this, the adolescent/adult sensory profile (AASP) questionnaire was distributed to 85 parents of typically developing children (P-TD), 121 parents from simplex ASD families (SPX), and 54…

Saghazadeh, Amene; Rezaei, Nima – Journal of Autism and Developmental Disorders, 2017
Brain-derived neurotrophic factor (BDNF) plays an important role in activity-dependent synaptic plasticity. Altered blood BDNF levels have been frequently identified in people with autism spectrum disorders (ASD). There are however wide discrepancies in the evidence. Therefore, we performed the present systematic review and meta-analysis aimed at…

The Integration of Occlusion and Disparity Information for Judging Depth in Autism Spectrum Disorder
Smith, Danielle; Ropar, Danielle; Allen, Harriet A. – Journal of Autism and Developmental Disorders, 2017
In autism spectrum disorder (ASD), atypical integration of visual depth cues may be due to flattened perceptual priors or selective fusion. The current study attempts to disentangle these explanations by psychophysically assessing within-modality integration of ordinal (occlusion) and metric (disparity) depth cues while accounting for sensitivity…

Kucharsky Hiess, R.; Alter, R.; Sojoudi, S.; Ardekani, B. A.; Kuzniecky, R.; Pardoe, H. R. – Journal of Autism and Developmental Disorders, 2015
Reduced corpus callosum area and increased brain volume are two commonly reported findings in autism spectrum disorder (ASD). We investigated these two correlates in ASD and healthy controls using T1-weighted MRI scans from the Autism Brain Imaging Data Exchange (ABIDE). Automated methods were used to segment the corpus callosum and intracranial…

This case-control study explores the association between pregnancy/birth complications and other factors with Autism Spectrum Disorder (ASD) in Lebanese subjects aged 2-18 years. Researchers interviewed 136 ASD cases from the American University of Beirut Medical Center Special Kids Clinic, and 178 controls selected by systematic digit dialing in…

Hyman, Susan L.; Stewart, Patricia A.; Foley, Jennifer; Cain, Usa; Peck, Robin; Morris, Danielle D.; Wang, Hongyue; Smith, Tristram – Journal of Autism and Developmental Disorders, 2016
To obtain information on the safety and efficacy of the gluten-free/casein-free (GFCF) diet, we placed 14 children with autism, age 3-5 years, on the diet for 4-6 weeks and then conducted a double-blind, placebo-controlled challenge study for 12 weeks while continuing the diet, with a 12-week follow-up. Dietary challenges were delivered via weekly…

The 16p11.2 duplication (BP4-BP5) is associated with Autism Spectrum Disorder (ASD), although significant heterogeneity exists. Quantitative ASD, behavioral and neuropsychological measures and DSM-IV diagnoses in child and adult carriers were compared with familial non-carrier controls, and to published results from deletion carriers. The 16p11.2…

We integrated multiple behavioural and developmental measures from multiple time-points using machine learning to improve early prediction of individual Autism Spectrum Disorder (ASD) outcome. We examined Mullen Scales of Early Learning, Vineland Adaptive Behavior Scales, and early ASD symptoms between 8 and 36 months in high-risk siblings (HR; n…

Zantinge, Gemma; van Rijn, Sophie; Stockmann, Lex; Swaab, Hanna – Journal of Autism and Developmental Disorders, 2017
This study aimed to assess physiological arousal and behavioral regulation of emotion in the context of frustration in 29 children with Autism Spectrum Disorders (ASD) and 45 typically developing children (41-81 months). Heart rate was continuously measured and emotion strategies were coded, during a locked-box task. Results revealed increases in…

Khemka, Ishita; Hickson, Linda; Mallory, Sarah B. – Journal of Autism and Developmental Disorders, 2016
This study was designed to assess the impact of a decision-making curriculum (PEER-DM) on the social peer relationship knowledge and self-protective decision-making skills of adolescents with disabilities in hypothetical situations involving negative peer pressure. A randomized design was used to assign students with disabilities from…

Atypical gaze processing has been reported in children with autism spectrum disorders (ASD). Here we explored how infants at risk for ASD respond behaviorally to others' direct gaze. We assessed 10-month-olds with a sibling with ASD (high risk group; n = 61) and a control group (n = 18) during interaction with an adult. Eye-tracking revealed less…

Funahashi, Atsushi; Gruebler, Anna; Aoki, Takeshi; Kadone, Hideki; Suzuki, Kenji – Journal of Autism and Developmental Disorders, 2014
We quantitatively measured the smiles of a child with autism spectrum disorder (ASD-C) using a wearable interface device during animal-assisted activities (AAA) for 7 months, and compared the results with a control of the same age. The participant was a 10-year-old boy with ASD, and a normal healthy boy of the same age was the control. They…
