To address this critical gap in the literature, the current study examined the predictive validity of (1) demographics, (2) core autism symptoms, (3) cognitive abilities and adaptive behavior, (4) comorbid psychopathology, and (5) medical problems, for suicide-related behaviors among autistic youth (N = 481; M(age) = 11.56 years). As indices of suicide-related behaviors, parents reported on whether the child had ever (1) talked about killing themselves, and (2) engaged in deliberate self-harm or attempted suicide. These two suicide-related outcomes had distinct clinical correlates, including child age, parental education, restricted and repetitive behaviors, IQ and adaptive behavior, affective and conduct problems, and medical concerns.

Atypical rapid audio-visual temporal recalibration in autism spectrum disorders / Jean‐Paul NOEL in Autism Research, 10-1 (January 2017)  

Public ISBD [article]  inAutism Research > 10-1 (January 2017) . - p.121-129 Titre : Atypical rapid audio-visual temporal recalibration in autism spectrum disorders Type de document : texte imprimé Auteurs : Jean‐Paul NOEL, Auteur ; Matthew A. DE NIEAR, Auteur ; Ryan A. STEVENSON, Auteur ; David ALAIS, Auteur ; Mark T. WALLACE, Auteur Article en page(s) : p.121-129 Langues : Anglais (eng) Mots-clés : autism  multisensory  audio-visual  plasticity  recalibration Index. décimale : PER Périodiques Résumé : Changes in sensory and multisensory function are increasingly recognized as a common phenotypic characteristic of Autism Spectrum Disorders (ASD). Furthermore, much recent evidence suggests that sensory disturbances likely play an important role in contributing to social communication weaknesses—one of the core diagnostic features of ASD. An established sensory disturbance observed in ASD is reduced audiovisual temporal acuity. In the current study, we substantially extend these explorations of multisensory temporal function within the framework that an inability to rapidly recalibrate to changes in audiovisual temporal relations may play an important and under-recognized role in ASD. In the paradigm, we present ASD and typically developing (TD) children and adolescents with asynchronous audiovisual stimuli of varying levels of complexity and ask them to perform a simultaneity judgment (SJ). In the critical analysis, we test audiovisual temporal processing on trial t as a condition of trial t − 1. The results demonstrate that individuals with ASD fail to rapidly recalibrate to audiovisual asynchronies in an equivalent manner to their TD counterparts for simple and non-linguistic stimuli (i.e., flashes and beeps, hand-held tools), but exhibit comparable rapid recalibration for speech stimuli. These results are discussed in terms of prior work showing a speech-specific deficit in audiovisual temporal function in ASD, and in light of current theories of autism focusing on sensory noise and stability of perceptual representations.

Brief Report: Arrested Development of Audiovisual Speech Perception in Autism Spectrum Disorders / Ryan A. STEVENSON in Journal of Autism and Developmental Disorders, 44-6 (June 2014)

A number of studies have shown that, in addition to auditory comprehension differences, individuals with autism frequently show atypical responses to audiovisual speech, suggesting a multisensory contribution to these communicative differences from their typically developing peers. To shed light on possible differences in the maturation of audiovisual speech integration, we tested younger (ages 6–12) and older (ages 13–18) children with and without ASD on a task indexing such multisensory integration. To do this, we used the McGurk effect, in which the pairing of incongruent auditory and visual speech tokens typically results in the perception of a fused percept distinct from the auditory and visual signals, indicative of active integration of the two channels conveying speech information. Whereas little difference was seen in audiovisual speech processing (i.e., reports of McGurk fusion) between the younger ASD and TD groups, there was a significant difference at the older ages. While TD controls exhibited an increased rate of fusion (i.e., integration) with age, children with ASD failed to show this increase. These data suggest arrested development of audiovisual speech integration in ASD. The results are discussed in light of the extant literature and necessary next steps in research.

This study explored relations between measures of sensory responsiveness and multisensory speech perception and integration in children with and without ASD. Participants were 8-17 year old children, 18 with ASD and 18 matched typically developing controls. Participants completed a psychophysical speech perception task, and parents reported on children's sensory responsiveness. Psychophysical measures (e.g., audiovisual accuracy, temporal binding window) were associated with patterns of sensory responsiveness (e.g., hyporesponsiveness, sensory seeking). Results indicate that differences in multisensory speech perception and integration covary with atypical patterns of sensory responsiveness.

Closing the species gap: Translational approaches to studying sensory processing differences relevant for autism spectrum disorder / Kaela E. SCOTT in Autism Research, 14-7 (July 2021)  

Public ISBD [article]  inAutism Research > 14-7 (July 2021) . - p.1322-1331 Titre : Closing the species gap: Translational approaches to studying sensory processing differences relevant for autism spectrum disorder Type de document : texte imprimé Auteurs : Kaela E.

STEVENSON, Auteur ; Susanne SCHMID, Auteur Article en page(s) : p.1322-1331 Langues : Anglais (eng) Mots-clés : Animals  Autism Spectrum Disorder  Cognition  Evoked Potentials  Humans  Mice  Perception  Sensation  auditory processing  experimental design  framework  sensory phenotypes  species translation Index. décimale : PER Périodiques Résumé : The study of sensory phenotypes has great potential for increasing research translation between species, a necessity to decipher the neural mechanisms that contribute to higher-order differences in neurological conditions such as autism spectrum disorder (ASD). Over the past decade, despite separate advances in our understanding of the structural and functional differences within the brain of autistic and non-autistic individuals and in rodent models for ASD, researchers have had difficulty translating the findings in murine species to humans, mostly due to incompatibility in experimental methodologies used to screen for ASD phenotypes. Focusing on sensory phenotypes offers an avenue to close the species gap because sensory pathways are highly conserved across species and are affected by the same risk-factors as the higher-order brain areas mostly responsible for the diagnostic criteria for ASD. By first reviewing how sensory processing has been studied to date, we direct our focus to electrophysiological and behavioral techniques that can be used to study sensory phenotypes consistently across species. Using auditory sensory phenotypes as a template, we seek to improve the accessibility of translational methods by providing a framework for collecting cohesive data in both rodents and humans. Specifically, evoked-potentials, acoustic startle paradigms, and psychophysical detection/discrimination paradigms can be created and implemented in a coordinated and systematic fashion across species. Through careful protocol design and collaboration, sensory processing phenotypes can be harnessed to bridge the gap that exists between preclinical animal studies and human testing, so that mutually held questions in autism research can be answered. LAY SUMMARY: It has always been difficult to relate results from animal research to humans. We try to close this gap by studying changes in sensory processing using careful protocol design and collaboration between clinicians and researchers. Sensory pathways are comparable between animals and humans, and are affected in the same way as the rest of the brain in ASD. Using changes in hearing as a template, we point the field in an innovative direction by providing a framework for collecting cohesive data in rodents and humans.
