Background
Aberrant attention patterns have been commonly reported in autistic children. However, few studies have examined attention to non-social stimuli varying in salience and complexity using eye-tracking technology, as well as their links to clinical sensory features.
Method
Forty-one children [16 with autism spectrum disorder (ASD), 10 with...
Importance: Children with autism spectrum disorder (ASD) and other developmental disabilities (DD) commonly display unusual responses to sensory input. Previous work has suggested concurrent associations linking sensory features with aspects of family functioning, including activity participation and caregiver strain. What is unknown, however, is t...
Prior research on the stability of sensory processing problems in children with autism spectrum disorder (ASD) or other developmental disabilities (DD) has produced inconsistent results. We employed a longitudinal study design to assess the stability of three clinical sensory response patterns: hyporesponsiveness; hyperresponsiveness; and sensory i...
Background:
Children with autism spectrum disorder (ASD) and other developmental disabilities (DD) exhibit sensory features that differ from their typically developing peers. Prior cross-sectional research has demonstrated significant associations between elevated sensory features and lower adaptive behavior scores, yet there is limited prospectiv...
Despite the challenges of achieving adequate sensitivity in screening at 12 months 1 , early identification of autism is essential for obtaining early services, which may improve developmental outcomes 2. • The First Years Inventory version 3.1 (FYI) 3 is a newly revised parent-report screener 2 designed to identify infants at around one year of ag...
Background and aims:
Early play behaviors may provide important information regarding later-diagnosed developmental delays. Play behaviors of young children with autism spectrum disorder (ASD) are restricted in diversity, frequency, and complexity. Most ASD research focuses on play in children over 18 months of age. This study examined three group...
This study used a gap-overlap paradigm to examine the impact of distractor salience and temporal overlap on the ability to disengage and orient attention in 50 children (4-13 years) with ASD, DD and TD, and associations between attention and sensory response patterns. Results revealed impaired disengagement and orienting accuracy in ASD. Disengagem...
Sensory features are prevalent and heterogeneous across children with ASD and these features have been associated with child outcomes. Identification of clinically defined sensory subtypes may enhance our understanding of unique phenotypes that have implications for etiology, prognosis, and intervention. This longitudinal study used a national onli...
Background
Sensory features are highly prevalent and heterogeneous among children with ASD. There is a need to identify homogenous groups of children with ASD based on sensory features (i.e. sensory subtypes) to inform research and treatment.Methods
Sensory subtypes and their stability over 1 year were identified through latent profile transition a...
Background: Existing research describes the atypical nature of play behaviors in young children (toddler age and older) with autism; however, little is reported about the earliest play behaviors of infants who are later diagnosed with autism. This study examined the play behaviors of three groups of infants (typically developing, later diagnosed wi...
This national online survey study characterized sensory features in 1,307 children with autism spectrum disorder (ASD) ages 2-12 years using the Sensory Experiences Questionnaire Version 3.0 (SEQ-3.0). Using the SEQ-3.0, a confirmatory factor analytic model with four substantive factors of hypothesized sensory response patterns (i.e., hyporesponsiv...
Neurobiological underpinnings of unusual sensory features in individuals with autism are unknown. Event-related potentials elicited by task-irrelevant sounds were used to elucidate neural correlates of auditory processing and associations with three common sensory response patterns (hyperresponsiveness; hyporesponsiveness; sensory seeking). Twenty-...
OBJECTIVE. This study explored precursors and trajectories of extreme sensory patterns in children with autism spectrum disorders (ASD) compared with children with developmental delay (DD).
METHOD. We conducted a retrospective analysis of home videos of 12 infants who later displayed extreme presence or absence of three sensory patterns at preschoo...

Our goal for this project has been to examine behaviors among infants and toddlers later diagnosed with autism spectrum disorder (ASD) or other developmental disorders compared to behaviors of infants with confirmed typical development. To address this goal, we have analyzed home videos recorded by parents or other nonresearchers in the child's usual environments from birth to 24 months. Behaviors examined include play, gestures, and sensory reactivity among others.
