Object play in infants with autism spectrum disorder: A longitudinal retrospective video analysis.

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.

Sensory subtypes and associated outcomes in children with autism spectrum disorders.

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 online survey aimed to identify associations of previously validated sensory subtypes to specific child and family characteristics and functional outcomes [vineland adaptive behavior scale-II (VABS) and parenting stress index short form (PSI)].

Eye Tracking Reveals Impaired Attentional Disengagement Associated with Sensory Response Patterns in Children with Autism.

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. Disengagement was impaired across all groups during temporal overlap for dynamic stimuli compared to static, but only ASD showed slower disengagement from multimodal relative to unimodal dynamic stimuli.

Attenuated auditory event-related potentials and associations with atypical sensory response patterns in children with autism.

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-eight children with autism and 39 typically developing children (4-12 year-olds) completed an auditory oddball paradigm.

Precursors and trajectories of sensory features: qualitative analysis of infant home videos.

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.
