We used the Sensory Processing 3-Dimensional (SP3-D) observed Assessment and parent-reported Inventory to examine sensory responsivity in 41 ASD and 33 typically-developing (TD) youth across 7-17 years. ASD youth had higher and more variable observed and reported sensory responsivity symptoms compared to TD, but the two measures were not correlated. Observed sensory over-responsivity (SOR) and sensory craving (SC) decreased with age in ASD, though SOR remained higher in ASD versus TD through adolescence. Results suggest that in ASD, the SP3-D Assessment can identify SOR through adolescence, and that there is value in integrating multiple sensory measures.

Cognitive reappraisal modulates neural responses to aversive sensory stimulation in autistic youth / Urvi T. SHAH in Journal of Child Psychology and Psychiatry, 67-12 (December 2026)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 67-12 (December 2026) . - p.2042-2055 Titre : Cognitive reappraisal modulates neural responses to aversive sensory stimulation in autistic youth Type de document : texte imprimé Auteurs : Urvi T. SHAH, Auteur ; Karrin EVANS, Auteur ; Megan BANCHIK, Auteur ; Apurva CHATURVEDI, Auteur ; Sapna RAMAPPA, Auteur ; Katie WONG, Auteur ; Jennifer A. SILVERS, Auteur ; Shulamite A. GREEN, Auteur Article en page(s) : p.2042-2055 Langues : Anglais (eng) Mots-clés : Sensory over-responsivity  autism spectrum disorder  cognitive reappraisal  fMRI Index. décimale : PER Périodiques Résumé : Background Sensory over-responsivity (SOR) is highly prevalent and impairing in autism spectrum disorder (ASD). SOR has been associated with sensory-limbic hyperresponsivity and reduced prefrontal top-down regulation during sensory stimulation. There are few evidence-based treatments for SOR, but cognitive reappraisal, an emotion regulation strategy, has been shown to reduce negative feelings through activation of frontal brain regions. The current study examined whether reappraisal changes neural reactivity to aversive sensory stimulation in autistic compared to typically developing (TD) children. Methods Forty-seven ASD and 45 age/IQ-matched TD youth aged 8?15?years participated in fMRI while experiencing aversive tactile stimulation on their arm and alternately focused either on how the stimulus made them feel (?React?), or how they would describe the stimuli objectively (?Reappraise?). Aversiveness ratings were provided after each stimulus. Parents reported on participants' SOR severity. Results Autistic youth showed reduced activation in sensory cortical regions during Reappraisal compared to React. Reappraisal also resulted in increased dorsomedial prefrontal cortex activation, with a trend toward more increases in the TD group but no significant group differences. Despite these reappraisal-related neural changes across both groups, only TD youth showed a reduction in aversiveness ratings for Reappraisal compared to React. Among ASD youth, higher SOR was associated with fewer decreases in sensory cortices but greater increases in frontal regions during Reappraisal compared to React. Older ASD youth also showed increased activity in the ventral prefrontal cortex during Reappraisal. Conclusions Results suggest that cognitive reappraisal modulates neural responses during sensory processing and, more specifically, may reduce hyperactivity in sensory cortical regions previously shown to be associated with SOR. However, individual differences such as age and SOR severity may affect the extent to which top-down cognitive processes are uniquely engaged during reappraisal.

Integrating parent report, observed behavior, and physiological measures to identify biomarkers of sensory over-responsivity in autism / Apurva CHATURVEDI in Journal of Neurodevelopmental Disorders, 17 (2025)  

Public ISBD [article]  inJournal of Neurodevelopmental Disorders > 17 (2025) Titre : Integrating parent report, observed behavior, and physiological measures to identify biomarkers of sensory over-responsivity in autism Type de document : texte imprimé Auteurs : Apurva CHATURVEDI, Auteur ; Sapna RAMAPPA, Auteur ; Ariana ANDERSON, Auteur ; Megan BANCHIK, Auteur ; Urvi SHAH, Auteur ; Michelle CRASKE, Auteur ; Shulamite GREEN, Auteur Langues : Anglais (eng) Mots-clés : Humans  Male  Female  Adolescent  Child  Autism Spectrum Disorder/physiopathology/diagnosis  Heart Rate/physiology  Parents  Biomarkers  Electrocardiography  Inhibition, Psychological  Behavior Observation Techniques  Autism spectrum disorder  Behavioral inhibition  Heart rate  Masking  Physiology  Sensory over-responsivity  Sensory processing  by the UCLA Institutional Review Board, and informed consent and assent were  obtained from the participants and their parents. Consent for publication: Not  applicable. Competing interests: The authors declare no competing interests. Index. décimale : PER Périodiques Résumé : BACKGROUND: Sensory over-responsivity (SOR) is a heightened reaction to environmental stimuli commonly seen in autism spectrum disorder (ASD) which impacts daily functioning. Parent-reported and observed behavioral assessments are used to study SOR, but show limited associations with each other, possibly because they measure different aspects of SOR or because children inhibit their responses during standardized assessments. Physiological measures provide an objective measure of sensory reactivity, and atypical heart rate (HR) responses to aversive stimuli have been shown to be related to SOR in ASD youth. This study aimed to compare how reported and observed measures of SOR predict HR and to examine if the level of reported behavioral inhibition in ASD youth affects how observed SOR behaviors correlate with physiological reactivity. METHODS: Participants were 54 typically developing (TD) and 83 ASD youth, ages 8-17, who completed a standardized behavioral assessment of SOR while electrocardiogram recordings were collected. Participants' parents also reported on their child's SOR symptoms and behavioral inhibition. RESULTS: ASD youth showed lower inter-beat-intervals (IBI; higher HR) across all auditory and tactile stimuli. For ASD youth, parent-reported SOR interacted with observed SOR to predict HR changes across the stimulation periods, indicating that ASD participants whose parents reported they had high SOR in their daily life, and showed high observed SOR in the lab assessment, exhibited reduced HR deceleration (orienting) after the onset of the stimulus and subsequent increased HR acceleration. Finally, we found that ASD participants who had lower parent-reported behavioral inhibition had a stronger correlation between observed SOR behavior and atypical HR responses. CONCLUSIONS: Results support prior findings that increased HR responses to aversive stimuli is related to both ASD and SOR. Furthermore, observed and parent-reported SOR interacted to predict HR, suggesting that a multi-method approach may best capture the extent of SOR for an individual. However, observed SOR measures may be most accurate for ASD youth who are less likely to inhibit their behavioral responses. This study illustrates the importance of integrating multiple measures of sensory reactivity to identify SOR. HR measures of sensory reactivity have the potential to serve as a biomarker of SOR across a diverse range of individuals.
