FREITAG, Auteur ; Christina LUCKHARDT, Auteur Article en page(s) : p.1500-1512 Langues : Anglais (eng) Mots-clés : Autism  selective attention  event-related potential  pupil dilation  perspective taking Index. décimale : PER Périodiques Résumé : Background Altered social cognition in autism may be influenced by difficulties in domain-general functions, such as selective attention. Here, we manipulated the requirement for selective attention during a visual perspective taking (VPT) task and used neurophysiological indices to delineate underlying mechanisms. Methods 43 autistic and 38 neurotypical children and youth completed a VPT paradigm. Participants' and an avatar's perspectives were either congruent or incongruent, manipulating the demand for selective attention to inhibit irrelevant information processing. Group differences in dependence on the attended perspective and congruency were examined for behavioral performance, event-related potentials (ERPs), and in a subsample, stimulus-evoked pupil response (SEPR). Results Autistic participants showed reduced accuracy when rating an avatar's perspective and pronounced perspective-related differences in a late-frontal slow wave (LFSW). Incongruency elicited stronger effects on behavioral performance and LFSW in autistic relative to neurotypical participants. Additionally, generally larger and more sustained SEPR was observed for autistic participants, reflecting an alteration that was dissociable from LFSW differences. Across groups, SEPR and ERP measures explained both distinct and partially overlapping variance in response slowing. Conclusions Findings support attenuated VPT abilities and difficulties to deploy selective attention in autistic youth. Altered fronto-cortical activation patterns in the LFSW likely reflect an increased top-down involvement in VPT. Concurrently, pupil responses indicate an increased cognitive effort when reporting visual perspectives. Findings emphasize a co-characterization of social cognition difficulties by social and domain-general functions in autism.

Intention Attribution in Children and Adolescents with Autism Spectrum Disorder: An EEG Study / Magdalena SCHÃœTZ in Journal of Autism and Developmental Disorders, 53-4 (April 2023)

FREITAG, Auteur ; Christina LUCKHARDT, Auteur Article en page(s) : p.1431-1443 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : The ability to infer intentions from observed behavior and predict actions based on this inference, known as intention attribution (IA), has been hypothesized to be impaired in individuals with autism spectrum disorder (ASD). The underlying neural processes, however, have not been conclusively determined. The aim of this study was to examine the neural signature of IA in children and adolescents with ASD, and to elucidate potential links to contextual updating processes using electroencephalography. Results did not indicate that IA or early contextual updating was impaired in ASD. However, there was evidence of aberrant processing of expectation violations in ASD, particularly if the expectation was based on IA. Results are discussed within the context of impaired predictive coding in ASD.

Transcranial Direct Current Stimulation of the Temporoparietal Junction in Autism Spectrum Disorder: Results of a Phase-IIa Randomized, Double-Blind, Sham-Controlled Feasibility Study / Christina LUCKHARDT in Autism Research, 18-9 (September 2025)

FREITAG, Auteur ; Magdalena SCHÃœTZ, Auteur Article en page(s) : p.1861-1876 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : ABSTRACT Activation of the temporoparietal junction (TPJ) is reduced in autism spectrum disorder (ASD) during social cognitive tasks. Therefore, anodal transcranial direct current stimulation (tDCS) of the TPJ may enhance social cognitive abilities in autistic individuals. In a multicenter, randomized, sham-controlled, double-blind parallel-group Phase-IIa trial, we investigated feasibility, safety, and effect sizes of 10 sessions of anodal tDCS of the bilateral TPJ at 2 mA as an add-on to computer-based social cognitive training in 10- to 17-year-old youth with autism. Feasibility of recruitment was low, with only 11% of screened individuals being randomized to tDCS (N=12) or sham (N=12). In contrast, retention in the study, data collection, intervention adherence, and technical feasibility were mostly excellent. No serious adverse events occurred, and stimulation was well tolerated. There were no differences in the prespecified primary outcome social responsiveness between sham and tDCS immediately after the intervention (standardized estimated effect size [ES]=0.098; 95%-confidence interval [95% CI] 1.043;1.240), but the sham group showed a trend for better social responsiveness at the 4 week follow-up (ES=1.106; 95% CI 0.054; 2.270). Secondary outcomes including questionnaires and event-related potentials showed improved compulsive behavior and quality of life by tDCS. High technical feasibility, participant retention, and safety highlight the potential of tDCS in autism and may inform future improvements in the feasibility of recruitment. The differential pattern of effect estimates indicates positive, but also potential negative effects of tDCS, which may vary due to tDCS stimulation parameters. The trial was prospectively registered in the German Clinical Trials Register (Deutsches Register für klinische Studien, DRKS, DRKS00014732).
