Attenuated Auditory Event-Related Potentials and Associations with Atypical Sensory Response Patterns in Children with Autism / Franc C L. DONKERS in Journal of Autism and Developmental Disorders, 45-2 (February 2015)

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. Results revealed marginally attenuated P1 and N2 to standard tones and attenuated P3a to novel sounds in autism versus controls. Exploratory analyses suggested that within the autism group, attenuated N2 and P3a amplitudes were associated with greater sensory seeking behaviors for specific ranges of P1 responses. Findings suggest that attenuated early sensory as well as later attention-orienting neural responses to stimuli may underlie selective sensory features via complex mechanisms.

Eye Tracking Reveals Impaired Attentional Disengagement Associated with Sensory Response Patterns in Children with Autism / Maura SABATOS-DEVITO in Journal of Autism and Developmental Disorders, 46-4 (April 2016)

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. Attentional disengagement had differential associations with distinct sensory response patterns in ASD and DD. Atypical sensory processing and temporal binding appear to be intertwined with development of disengagement in ASD, but longitudinal studies are needed to unravel causal pathways.

Using the SEQ-3.0, a confirmatory factor analytic model with four substantive factors of hypothesized sensory response patterns (i.e., hyporesponsiveness; hyperresponsiveness; sensory interests, repetitions and seeking behaviors; enhanced perception), five method factors of sensory modalities (i.e., auditory, visual, tactile, gustatory/olfactory, vestibular/proprioceptive), and one of social context were tested with good model fit. Child and family characteristics associated with the sensory response patterns were explored. The effect of sensory response patterns on autism severity was tested, controlling for key child and family characteristics. The SEQ-3.0 demonstrates an empirically valid factor structure specific to ASD that considers sensory response patterns, modalities, and social context.

Object play in infants with autism spectrum disorder: A longitudinal retrospective video analysis / Kaitlyn P. WILSON in Autism & Developmental Language Impairments, 2 (January-December 2017)

BARANEK, Auteur Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Background and aimsEarly play behaviors may provide important information regarding later-diagnosed developmental delays. Play behaviors of young children with autism spectrum disorder are restricted in diversity, frequency, and complexity. Most autism spectrum disorder research focuses on play in children over 18 months of age. This study examined three groups of infants (later diagnosed with autism spectrum disorder, later diagnosed with other developmental disorders, and typically developing) with the aims of: (1) describing the play behaviors of the three groups of infants at two time points (9?12 months and 15?18 months); (2) examining group differences in four hierarchical levels of play at both time points; (3) comparing groups with respect to the highest level of play achieved; and (4) determining if the highest level of play achieved by infants with autism spectrum disorder and other developmental delays correlated with later developmental outcomes.MethodsThe current study used longitudinal retrospective video analysis to examine object play behaviors of the three groups of infants (total n=92) at two time points (time 1: 9?12 months of age, and time 2: 15?18 months of age). Coding of play behaviors was based on existing literature and distribution of data from the current study. Developmental outcomes examined were measured using the Vineland Adaptive Behavior Scales, Childhood Autism Rating Scale, and a non-verbal developmental quotient calculated using visual reception scores from the Mullen Scales for Early Learning.ResultsResults indicate group differences in play, with infants later diagnosed with autism spectrum disorder showing significantly less sophisticated play than those with typical development. In addition, modest but significant correlations were found between highest level of play achieved at time 1 (9?12 months) and time 2 (15?18 months) and later outcomes for the autism spectrum disorder group.Conclusions and implicationsResults suggest that examination of infant play behaviors is important for early screening and intervention planning to potentially mitigate effects on later developmental outcomes.

Sensory subtypes and associated outcomes in children with autism spectrum disorders / Karla K. AUSDERAU in Autism Research, 9-12 (December 2016)

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)]. The sensory experiences questionnaire-3.0 was collected from caregivers with children with ASD, ages 2–12, at two time points (Time 1, n?=?1307, Time 2, n?=?884), 1 year apart. Functional outcomes assessments were collected at the second time point. A latent profile transition analysis (LPTA) was used to test associations, and results indicated that the attenuated-preoccupied subtype presented with the significantly lowest levels of VABS adaptive behavior composite scores compared to the other three sensory subtypes. Both the VABS maladaptive behavior index and the total PSI score were significantly highest in the extreme-mixed subtype. These results underscore the clinical utility of this subtyping approach for differentiating characteristics and functional outcomes associated with clinically defined sensory phenotypes. These findings may have implications for better understanding etiology, prognosis, and more precise targets for interventions designed to ameliorate sensory difficulties, and ultimately mitigate negative developmental consequences and parenting stress.
