The Combination of Food Approach and Food Avoidant Behaviors in Children with Autism Spectrum Disorder: "Selective Overeating"
Peer reviewed Peer reviewed
Direct linkDirect link
Nadeau, Monica V.; Richard, Emily; Wallace, Gregory L. – Journal of Autism and Developmental Disorders, 2022
Based on parent questionnaires, we demonstrate the presence of an eating pattern among children with autism spectrum disorder (ASD) that is characterized by both food selectivity and eating in the absence of hunger. Children with ASD were categorized as engaging in eating patterns of selective overeating, selective eating only, overeating only, or…

Brief Report: Performance-Based Executive Functioning Abilities Are Associated with Caregiver Report of Adaptive Functioning in Autism Spectrum Disorder
Peer reviewed Peer reviewed

Udhnani, Manisha D.; Kenworthy, Lauren; Wallace, Gregory L.; Yerys, Benjamin E. – Journal of Autism and Developmental Disorders, 2020
Executive functioning is thought to contribute to adaptive behavior skills development in individuals with autism spectrum disorder (ASD). However, supporting data are largely based on caregiver reports of executive functioning. The current study evaluated whether performance-based measures of executive functioning (working memory and inhibition)…

Wallace, Gregory L.; Dudley, Katerina; Anthony, Laura; Pugliese, Cara E.; Orionzi, Bako; Clasen, Liv; Lee, Nancy Raitano; Giedd, Jay N.; Martin, Alex; Raznahan, Armin; Kenworthy, Lauren – Journal of Autism and Developmental Disorders, 2017
Although social-communication difficulties and repetitive behaviors are hallmark features of autism spectrum disorder (ASD) and persist across the lifespan, very few studies have compared age-related differences in these behaviors between youth with ASD and same-age typically developing (TD) peers. We examined this issue using SRS-2 (Social…

Longitudinal Examination of Adaptive Behavior in Autism Spectrum Disorders: Influence of Executive Function
Peer reviewed Peer reviewed
Direct linkDirect link
Pugliese, Cara E.; Anthony, Laura Gutermuth; Strang, John F.; Dudley, Katerina; Wallace, Gregory L.; Naiman, Daniel Q.; Kenworthy, Lauren – Journal of Autism and Developmental Disorders, 2016
This study characterizes longitudinal change in adaptive behavior in 64 children and adolescents with autism spectrum disorder (ASD) without intellectual disability evaluated on multiple occasions, and examines whether prior estimate of executive function (EF) problems predicts future adaptive behavior scores. Compared to standardized estimates…

Increasing Adaptive Behavior Skill Deficits from Childhood to Adolescence in Autism Spectrum Disorder: Role of Executive Function
Peer reviewed Peer reviewed

Pugliese, Cara E.; Anthony, Laura; Strang, John F.; Dudley, Katerina; Wallace, Gregory L.; Kenworthy, Lauren – Journal of Autism and Developmental Disorders, 2015
Almost half of all children with autism spectrum disorder have average cognitive abilities, yet outcome remains poor. Because outcome in HFASD is more related to adaptive behavior skills than cognitive level it is important to identify predictors of adaptive behavior. This study examines cognitive and demographic factors related to adaptive…

Brief Report: IQ Split Predicts Social Symptoms and Communication Abilities in High-Functioning Children with Autism Spectrum Disorders
Peer reviewed Peer reviewed
Direct linkDirect link
Black, David O.; Wallace, Gregory L.; Sokoloff, Jennifer L.; Kenworthy, Lauren – Journal of Autism and Developmental Disorders, 2009
We investigated the relationship of discrepancies between VIQ and NVIQ (IQ split) to autism symptoms and adaptive behavior in a sample of high-functioning (mean FSIQ = 98.5) school-age children with autism spectrum disorders divided into three groups: discrepantly high VIQ (n = 18); discrepantly high NVIQ (n = 24); and equivalent VIQ and NVIQ (n =…
