Altered perception-action binding modulates inhibitory control in Gilles de la Tourette syndrome / Vanessa PETRUO in Journal of Child Psychology and Psychiatry, 60-9 (September 2019)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 60-9 (September 2019) . - p.953-962 Titre : Altered perception-action binding modulates inhibitory control in Gilles de la Tourette syndrome Type de document : texte imprimé Auteurs : Vanessa PETRUO, Auteur ; Benjamin BODMER, Auteur ; Valerie C. BRANDT, Auteur ; Leoni BAUMUNG, Auteur ; Veit ROESSNER, Auteur ; A. MUNCHAU, Auteur ; Christian BESTE, Auteur Article en page(s) : p.953-962 Langues : Anglais (eng) Mots-clés : Tourette syndrome  cognitive control  event related potential  neurophysiology  response inhibition, inferior parietal cortex, theory of event coding Index. décimale : PER Périodiques Résumé : BACKGROUND: Gilles de la Tourette Syndrome (GTS) is a multifaceted neuropsychiatric developmental disorder with onset in childhood or adolescence and frequent remissions in early adulthood. A rather new emerging concept of this syndrome suggests that it is a disorder of purposeful actions, in which sensory processes and their relation to motor responses (actions) play a particularly important role. Thus, this syndrome might be conceived as a condition of altered 'perception-action binding'. In the current study, we test this novel concept in the context of inhibitory control. METHODS: We examined N = 35 adolescent GTS patients and N = 39 healthy controls in a Go/Nogo-task manipulating the complexity of sensory information triggering identical actions; i.e. to inhibit a motor response. This was combined with event-related potential recordings, EEG data decomposition and source localization. RESULTS: GTS patients showed worse performance compared to controls and larger performance differences when inhibitory control had to be exerted using unimodal visual compared to bimodal auditory-visual stimuli. This suggests increased binding between bimodal stimuli and responses leading to increased costs of switching between responses instructed by bimodal and those instructed by unimodal stimuli. The neurophysiological data showed that this was related to mechanisms mediating between stimulus evaluation and response selection; i.e. perception-action binding processes in the right inferior parietal cortex (BA40). CONCLUSIONS: Stimulus-action inhibition binding is stronger in GTS patients than healthy controls and affects inhibitory control corroborating the concept suggesting that GTS might be a condition of altered perception-action integration (binding); i.e. a disorder of purposeful actions.

Arousal-modulated memory encoding and retrieval in adults with autism spectrum disorder / Nico BAST in Autism Research, 15-9 (September 2022)  

Public ISBD [article]  inAutism Research > 15-9 (September 2022) . - p.1609-1620 Titre : Arousal-modulated memory encoding and retrieval in adults with autism spectrum disorder Type de document : texte imprimé Auteurs : Nico BAST, Auteur ; Sebastian B.

At the time of publication, we were unaware of specific data-analysis methods that can be used to shed further light on the origins of such memory related pupil dilation. Specifically, by distinguishing "tonic" from "phasic" changes in pupil dilation and considering their temporal progression, it is possible to draw inferences about the functional integrity of a locus coeruleus-norepinephrine system (LC-NE) that is known to play a key role in regulating memory encoding and retrieval processes. We therefore apply these analyses to our previously published eye-tracking data of adults with ASD (N = 24) and neurotypical development (TD, N = 30) during the recognition memory task. In this re-analysis, we related pupil dilation during encoding and retrieval to recognition accuracy in a per-trial analysis of linear mixed models. In ASD, we replicated attenuated recognition accuracy, which was accompanied by attenuated pupil dilation during encoding and retrieval. Group differences in pupil dilation during retrieval occurred late during the trial (after 1.75s) and indicated an altered top-down processing like attenuated attribution of semantic salience in response to previously encoded stimuli. In addition, only in the ASD group were higher pupil dilation during encoding and lower pupil dilation during retrieval associated with decreased recognition accuracy. This supports altered modulation of memory encoding and retrieval in ASD, with LC-NE phasic activity as promising underlying mechanism. LAY SUMMARY: We investigated the changes of pupil size during memory testing in autism spectrum disorder. Adults with ASD remembered fewer items correctly than neurotypical individuals (TD). This reduced memory was related to increased pupillary responses at study and decreased pupil dilation at test only for adults with ASD indicating a different modulation of memory by the locus coeruleus.

Assessing Anxiety in Autistic and Non-Autistic Youth: Validation of the German Parent Version of the Anxiety Scale for Children With Autism Spectrum Disorder / Magdalena GRUNER in Autism Research, 18-11 (November 2025)

The Anxiety Scale for Children with Autism Spectrum Disorder?Parent Version (ASC-ASD-P) was designed to address this issue, but its utility in German clinical settings has not been established. This study validated the German translation of the ASC-ASD-P in a clinical sample of 317 participants presenting at a clinic for autism assessment, including 120 autistic youth. Internal consistency was excellent (Cronbach's α?=?0.92), and convergent validity was demonstrated through significant correlations with established psychopathology measures such as the Child Behavior Checklist (CBCL) and Strengths and Difficulties Questionnaire (SDQ). Factor analyses preferred a 4-factor structure in the autism group, but indicated difficulties replicating the Separation Anxiety Subscale. Autistic youth showed higher total anxiety and uncertainty scores compared to non-autistic youth, underlining the scale's sensitivity to autism-specific anxiety patterns. By including youth with intellectual disabilities, often underrepresented in research, this study provides a more comprehensive evaluation of the ASC-ASD-P's applicability across the autism spectrum. These findings support the ASC-ASD-P as a reliable tool for assessing anxiety in German-speaking autistic youth while highlighting areas where refinement could strengthen its utility.

Here, we study efficacy of the low-intensity, complex NDBI ?Frankfurt Early Intervention Program for ASD? (A-FFIP) over 1 year by a confirmatory phase-III, prospective, randomised, controlled, parallel-group study with two treatment arms over four centres. Methods Main inclusion criteria: ASD (DSM-5), age 24 66 months, developmental quotient >30. Intervention: Manualised A-FFIP intervention. Control intervention: Early intervention as usual (EIAU). Primary outcome: Change in core ASD symptoms from baseline (T2) to immediate intervention endpoint at 12 months (T6) based on the blindly rated Brief Observation for Communication Change (BOSCC) total score. Statistical analysis: Mixed model for repeated measures with covariates baseline BOSCC-total, chronological age and centre. Results Between July 2018 and October 2021, N 134 children with ASD were randomly allocated to intervention (A-FFIP: n 68, EIAU: n 66). Groups did not differ at baseline, with a mean age of 49 (SD 10) months, a mean developmental age of 23.3 (SD 13.6) months and 26 (19.4%) females. The SARS-CoV-2 pandemic interfered severely with trial procedures. Intention-to-treat analysis in the primary analysis set, with at least one postbaseline BOSCC measure (A-FFIP n 64, EIAU n 60), did not find differences in the primary outcome by group (adjusted ES 0.06, 95% CI to 0.24 to 0.11). SARS-CoV2-related lockdown led to less improvement across groups. Secondary outcomes showed stronger improvements in parent-rated repetitive behaviour as well as parent- and teacher-rated executive functions for A-FFIP versus EIAU. Adverse events were comparable between groups. Conclusions The manualised NDBI program A-FFIP, which allows individually targeting six core basic abilities and five developmental domains related to longitudinal development in ASD, did not improve social communication, cognitive or behavioural outcomes beyond EIAU after 1 year, but may improve repetitive behaviour and executive function.

However, the exact underlying mechanisms, such as sensory dominance possibly caused by imprecise priors and/or increased sensory precision, remain elusive. The ?Bayesian brain framework offers refined methods to investigate these mechanisms. This study utilized both model-free (frequentist statistics) and model-based (hierarchical Drift Diffusion Modeling) analytical approaches to compare gender face aftereffects in male adolescents with autism (n 29) to neurotypical controls (n 39) using a behavioral choice experiment. Contrary to our initial hypotheses, our analyses did not find support for imprecise priors or increased sensory precision within the autistic group. Instead, we observed generally decreased drift rates towards male but not female stimuli in the autistic group. Thus, our findings suggest a lack of own-gender bias in face processing among the autistic participants. These findings align with more recent behavioral and neurophysiological research observing intact priors in individuals with autism, suggesting that other mechanisms may better explain the perceptual challenges in autism. Our study contributes to the ongoing discourse on perceptual processing in autism, emphasizing the necessity for more nuanced analytical approaches in order to unravel the complexity of this condition.
