Brief Report: Specificity of Interpersonal Synchrony Deficits to Autism Spectrum Disorder and Its Potential for Digitally Assisted Diagnostics / Jana Christina KOEHLER in Journal of Autism and Developmental Disorders, 52-8 (August 2022)

Titre : Brief Report: Specificity of Interpersonal Synchrony Deficits to Autism Spectrum Disorder and Its Potential for Digitally Assisted Diagnostics Type de document : Texte imprimé et/ou numérique Auteurs : Jana Christina KOEHLER, Auteur ; Alexandra Livia GEORGESCU, Auteur ; Johanna WEISKE, Auteur ; Moritz SPANGEMACHER, Auteur ; Lana BURGHOF, Auteur ; Peter FALKAI, Auteur ; Nikolaos KOUTSOULERIS, Auteur ; Wolfgang TSCHACHER, Auteur ; Kai VOGELEY, Auteur ; Christine M. FALTER-WAGNER, Auteur Article en page(s) : p.3718-3726 Langues : Anglais (eng) Mots-clés : Adult Autism Spectrum Disorder/diagnosis Humans Mass Screening Autism spectrum disorder Diagnostics Interpersonal synchrony Motion energy analysis Social interaction Index. décimale : PER Périodiques Résumé : Reliably diagnosing autism spectrum disorders (ASD) in adulthood poses a challenge to clinicians due to the absence of specific diagnostic markers. This study investigated the potential of interpersonal synchrony (IPS), which has been found to be reduced in ASD, to augment the diagnostic process. IPS was objectively assessed in videos of diagnostic interviews in a representative referral population from two specialized autism outpatient clinics. In contrast to the current screening tools that could not reliably differentiate, we found a significant reduction of IPS in interactions with individuals later diagnosed with ASD (n=16) as opposed to those not receiving a diagnosis (n=23). While these findings need to be validated in larger samples, they nevertheless underline the potential of digitally-enhanced diagnostic processes for ASD.

Titre : Reduced nonverbal interpersonal synchrony in autism spectrum disorder independent of partner diagnosis: a motion energy study Type de document : Texte imprimé et/ou numérique Auteurs : Alexandra Livia GEORGESCU, Auteur ; S. KOEROGLU, Auteur ; Antonia HAMILTON, Auteur ; Kai VOGELEY, Auteur ; C. M. FALTER-WAGNER, Auteur ; W. TSCHACHER, Auteur Article en page(s) : 11 p. Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Autism spectrum disorders Conversation Dyadic interactions Interactional heterogeneity Interpersonal coordination Interpersonal synchrony Motion energy Motion energy analysis Nonverbal behaviour Social interaction Index. décimale : PER Périodiques Résumé : BACKGROUND: One of the main diagnostic features of individuals with autism spectrum disorders is nonverbal behaviour difficulties during naturalistic social interactions. The 'Interactional Heterogeneity Hypothesis' of ASD proposes that the degree to which individuals share a common ground substantially influences their ability to achieve smooth social interactions. METHODS: To test this hypothesis, we filmed 29 autistic and 29 matched typically developed adults engaged in several conversational tasks. Windowed cross-lagged correlations were computed using the time series of motion energy of both individuals in a dyad. These coefficients were then compared across the three dyad types that were homo- or heterogenous with respect to diagnosis: pairs of two autistic individuals, two typically developed individuals or pairs of one autistic and one typically developed person. RESULTS: We found that all dyad types achieved above-chance interpersonal synchrony, but that synchrony was more expressed in typical dyads compared to both autistic and mixed dyads. LIMITATIONS: The method presented here provides only one, albeit objective and robust, approach to explore synchrony. The methodological choices as well as the lack of consideration for other communication modalities may limit our interpretation of the findings. Moreover, the sample size is small with respect to exploring associations between synchrony and various outcome and social skill measures. CONCLUSIONS: The present results do not provide support for the Interactional Heterogeneity Hypothesis given that autistic individuals do not coordinate better when interacting with another autistic individual, compared to when interacting with a typical individual.
