Garcia-Pastor, T.; Salinero, J. J.; Theirs, C. I.; Ruiz-Vicente, D. – Journal of Autism and Developmental Disorders, 2019
The purpose of the present study was to compare body composition and physical activity level between children and adults with Autism Spectrum Disorders (ASD). A sample of 78 children, adolescents and adults participated in the study. Anthropometrics and physical activity, using GT1M accelerometer, were assessed. Overweight and obesity prevalence…

Hartley, Matthew; Dorstyn, Diana; Due, Clemence – Journal of Autism and Developmental Disorders, 2019
Mindfulness-based therapies are rising in popularity. However, evidence for their effectiveness in reducing psychological distress and enhancing wellbeing for families living with autism spectrum disorder (ASD) is limited. A systematic search identified 10 independent studies, involving a pooled sample of 233 children and adults with ASD and 241…

Van Herwegen, Jo; Ranzato, Erica; Karmiloff-Smith, Annette; Simms, Victoria – Journal of Autism and Developmental Disorders, 2019
It has been reported that approximate number sense (ANS) task performance is impaired in individuals with Williams syndrome (WS) and Down syndrome (DS). Research with infants has suggested this impairment is caused by sticky fixation in WS and sustained attention deficits for those with DS. This study examined looking patterns of older children…

Chawner, L. R.; Blundell-Birtill, P.; Hetherington, M. M. – Journal of Autism and Developmental Disorders, 2019
People with developmental disorders (DD) often display high levels of selective eating, which can result in micronutrient deficiencies. It is therefore essential to explore ways to increase dietary variety in this population. To identify different types of interventions promoting increased acceptance of new foods or dietary variety for DD…

Nicholson, Toby; Williams, David; Carpenter, Katie; Kallitsounaki, Aimilia – Journal of Autism and Developmental Disorders, 2019
Interoception (the ability to sense what's going on inside one's body) is considered integral to many higher-order cognitive processes. Some have speculated that impaired interoception may underpin some features of ASD. Yet, in Experiment 1, we found no evidence of a between-group difference in either cardiac or respiratory interoceptive accuracy…

Carrington, Sarah J.; Barrett, Sarah L.; Sivagamasundari, Umapathy; Fretwell, Christine; Noens, Ilse; Maljaars, Jarymke; Leekam, Susan R. – Journal of Autism and Developmental Disorders, 2019
The rate of diagnosis of autism in adults has increased over recent years; however, the profile of behaviours in these individuals is less understood than the profile seen in those diagnosed in childhood. Better understanding of this profile will be essential to identify and remove potential barriers to diagnosis. Using an abbreviated form of the…

Platos, Mateusz; Wojaczek, Kinga – Journal of Autism and Developmental Disorders, 2018
Peer-mediated intervention (PMI) is most commonly defined as a treatment approach that engages typically developing peers to teach children with autism spectrum disorders (ASD) social skills and increase their social interactions, mainly in a school setting. In this letter, we address the limitations of such understanding of PMI and review the…

Kaluzna-Czaplinska, Joanna; Zurawicz, Ewa; Józwik-Pruska, Jagoda – Journal of Autism and Developmental Disorders, 2018
Autism spectrum disorder (ASD) describes a set of neurodevelopmental disorders. Despite extensive ASD research lasting more than 60 years, its causes are still unknown. Without indicating the etiology, its development cannot be stopped. Over the years, both the definition and diagnostic criteria have developed. The number of ASD incidence is…

Martínez-González, A. E.; Piqueras, J. A. – Journal of Autism and Developmental Disorders, 2018
Restricted and repetitive behavior (RRB) is one of the two key diagnostic features of autism spectrum disorder (ASD). DSM-5 highlights the importance of severity-based diagnostic modifiers assigned on the basis of intensity of needed supports. Therefore, there is a need for available measures that assess the severity of RRB. The repetitive…

Lugo Marín, Jorge; Rodríguez-Franco, Montserrat Alviani; Mahtani Chugani, Vinita; Magán Maganto, María; Díez Villoria, Emiliano; Canal Bedia, Ricardo – Journal of Autism and Developmental Disorders, 2018
Since their separation as independent diagnostics, autism spectrum disorders (ASD) and schizophrenia spectrum disorders (SSD) have been conceptualized as mutually exclusive disorders. Similarities between both disorders can lead to misdiagnosis, especially when it comes to average-IQ adults who were not identified during childhood. The aim of this…

Crane, Laura; Batty, Richard; Adeyinka, Hanna; Goddard, Lorna; Henry, Lucy A.; Hill, Elisabeth L. – Journal of Autism and Developmental Disorders, 2018
Accessing an autism diagnosis is a key milestone, both for an individual and their family. Using a qualitative methodology, the current study examined the views and experiences of ten autistic adults, ten parents of children on the autism spectrum, and ten professionals involved in autism diagnosis, all based in the United Kingdom (UK).…

C.; Zander, E.; Charman, T. – Journal of Autism and Developmental Disorders, 2018
Research on sex-related differences in Autism Spectrum Disorder (ASD) has been impeded by small samples. We pooled 28 datasets from 18 sites across nine European countries to examine sex differences in the ASD phenotype on the ADI-R (376 females, 1763 males) and ADOS (233 females, 1187 males). On the ADI-R, early childhood restricted and…

Nuttall, Amy K.; Coberly, Ben; Diesel, Sara J. – Journal of Autism and Developmental Disorders, 2018
Typically developing siblings (TDS) of individuals with Autism Spectrum Disorder (ASD) frequently serve as caregivers during childhood, known as parentification, and primary caregivers for siblings in adulthood. In order to evaluate mechanisms linking these roles, we surveyed emerging-adult TDS (N = 108) about childhood parentification roles…

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,…

Maule, John; Stanworth, Kirstie; Pellicano, Elizabeth; Franklin, Anna – Journal of Autism and Developmental Disorders, 2018
It has been suggested that attenuated adaptation to visual stimuli in autism is the result of atypical perceptual priors (e.g., Pellicano and Burr in "Trends Cogn Sci" 16(10):504-510, 2012. doi:10.1016/j.tics.2012.08.009). This study investigated adaptation to color in autistic adults, measuring both strength of afterimage and the…
