Kelly, M. P.; Reed, P. – Focus on Autism and Other Developmental Disabilities, 2021
"Stimulus over-selectivity" describes a phenomenon in which an individual responds only to a subset of the stimuli present in the environment and, thus, may restrict learning. This study aimed to develop understanding of the nature and role of over-selectivity in autism spectrum disorder (ASD) by analyzing the relationship of…

Piwowarczyk, Anna; Horvath, Andrea; Pisula, Ewa; Kawa, Rafal; Szajewska, Hania – Journal of Autism and Developmental Disorders, 2020
To determine whether a gluten-free diet (GFD) compared with a gluten-containing diet (GD) influences functioning of children with autism spectrum disorders (ASD), we performed a randomized, controlled, single-blinded trial. Sixty-six children (36-69 months) with ASD, within the normal IQ (> 70) range, who had been on a GFD for at least 8 weeks…

Rosello, Rocio; Martinez-Raga, Jose; Mira, Alvaro; Pastor, Juan Carlos; Solmi, Marco; Cortese, Samuele – Autism: The International Journal of Research and Practice, 2022
Attention-deficit/hyperactivity disorder is one of the most common comorbidities in individuals with autism spectrum disorder. However, the clinical implications of the co-occurrence of these two disorders are still poorly understood. Based on a preregistered protocol (PROSPERO CRD42020193880), this systematic review identified 34 articles,…

Page, Shayleigh Dickson; Souders, Margaret C.; Kral, Tanja V. E.; Chao, Ariana M.; Pinto-Martin, Jennifer – Journal of Autism and Developmental Disorders, 2022
Feeding difficulties related to selective intake, or eating a limited variety of foods, are very common in children with autism spectrum disorder (ASD). A systematic search of PubMed, Embase, PsycInfo, and CINAHL identified 29 studies that evaluated eight correlates: age, ASD symptoms and severity, cognitive and adaptive skills, sensory processing…

Salomone, Erica; Shephard, Elizabeth; Milosavljevic, Bosiljka; Johnson, Mark H.; Charman, Tony; Baron-Cohen, Simon; Bedford, Rachael; Bolton, Patrick; Chandler, Susie; Elsabbagh, Mayada; Fernandes, Janice; Garwood, Holly; Gliga, Teodora; Hudry, Kristelle; Jones, Emily J. H.; Pasco, Greg; Pickles, Andrew; Tucker, Leslie; Volein, Agnes – Journal of Autism and Developmental Disorders, 2018
Cognitive and adaptive behaviour abilities early in life provide important clinical prognostic information. We examined stability of such skills in children at high familial risk for ASD who either met diagnostic criteria for ASD at age 7 years (HR-ASD, n = 15) or did not (HR-non-ASD, n = 24) and low-risk control children (LR, n = 37),…

Rosen, Nicole E.; McCauley, James B.; Lord, Catherine – Autism: The International Journal of Research and Practice, 2022
Siblings play an important role in shaping the developmental trajectories of individuals with autism spectrum disorder. Having siblings has been associated with better social communication, non-verbal communication, and theory of mind abilities in autism spectrum disorder. However, little is known about the impact of siblings on adaptive skill…

Chakraborty, Payal; Carpenter, Kimberly L. H.; Major, Samantha; Deaver, Megan; Vermeer, Saritha; Herold, Brianna; Franz, Lauren; Howard, Jill; Dawson, Geraldine – Autism: The International Journal of Research and Practice, 2021
Individuals with autism spectrum disorder are more likely than typically developing individuals to experience a range of gastrointestinal abnormalities, including chronic diarrhea, constipation, food sensitivities, and abdominal pain. These gastrointestinal symptoms have been associated with higher levels of irritability and aggressive behavior,…

Duncan, Amie; Tamm, Leanne; Birnschein, Allison M.; Becker, Stephen P. – Autism: The International Journal of Research and Practice, 2019
Adolescents with autism spectrum disorder frequently experience social communication difficulties, executive functioning deficits, and anxiety and depressive symptoms, which are similar to the symptoms and correlates of sluggish cognitive tempo. Although sluggish cognitive tempo is related to, but distinct from, the inattentive and…

Bradshaw, Jessica; Gillespie, Scott; Klaiman, Cheryl; Klin, Ami; Saulnier, Celine – Autism: The International Journal of Research and Practice, 2019
Individuals with autism spectrum disorder and average IQ exhibit a widening discrepancy between lagging adaptive skills relative to their cognitive potential, but it is unknown when this discrepancy emerges in development. To address this important question, we measured adaptive and cognitive skills longitudinally, from 12-36 months, in 96…

Juergensen, Kaitlin; Mattingly, Rhonda; Pitts, Teresa; Smith, Alan F. – Early Years: An International Journal of Research and Development, 2021
Autism spectrum disorder (ASD) is a heterogeneous neurodevelopmental disorder whose symptoms may involve deficits across three domains: communication, socialization and atypical behaviors or interests. With a high prevalence across populations and a tendency to impact males more than females, early and accurate diagnosis appears critical. The most…

Zachor, Ditza A.; Ben-Itzchak, Esther – Journal of Autism and Developmental Disorders, 2019
High rates of attention deficit/hyperactivity disorder (ADHD) comorbidity have been described in autism spectrum disorder (ASD). This study searched for predictors at toddlerhood of the severity of ADHD symptoms at adolescence. The study included 65 participants, (mean age = 13:8 year), diagnosed with ASD at toddlerhood. Participants underwent a…

Pinchover, Shulamit; Shulman, Cory – Early Child Development and Care, 2019
Play and playfulness have a key role in children's development. Not enough is known about the playfulness of children with autism spectrum disorder (ASD) and its relationship to children's behavioural problems, as well as the role of caregiver behaviours during play in this relationship. The present study examines the moderating role of teachers'…
