We presented either social stimuli (humans) or non-social stimuli (objects or animals). ASD were slower to recognize images during their emergence, but as fast as CON when indicating the dissipation of the image irrespective of its content. Social stimuli were recognized faster and remained discernable longer in both diagnostic groups. Thus, ASD participants show a largely intact preference for the processing of social images. An exploratory analysis of response subsets reveals subtle differences between groups that could be investigated in future studies.

Sex-Related Cognitive Profile in Autism Spectrum Disorders Diagnosed Late in Life: Implications for the Female Autistic Phenotype / Fritz-Georg LEHNHARDT in Journal of Autism and Developmental Disorders, 46-1 (January 2016)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 46-1 (January 2016) . - p.139-154 Titre : Sex-Related Cognitive Profile in Autism Spectrum Disorders Diagnosed Late in Life: Implications for the Female Autistic Phenotype Type de document : texte imprimé Auteurs : Fritz-Georg LEHNHARDT, Auteur ; Christine M. FALTER-WAGNER, Auteur ; Astrid GAWRONSKI, Auteur ; Kathleen PFEIFFER, Auteur ; Ralf TEPEST, Auteur ; Jeremy FRANKLIN, Auteur ; Kai VOGELEY, Auteur Année de publication : 2016 Article en page(s) : p.139-154 Langues : Anglais (eng) Mots-clés : Autisme féminin  Autism spectrum disorder  Adulthood  Cognitive profile  Female autistic phenotype  Processing speed Index. décimale : PER Périodiques Résumé : Females with high-functioning ASD are known to camouflage their autistic symptoms better than their male counterparts, making them prone to being under-ascertained and delayed in diagnostic assessment. Thus far the underlying cognitive processes that enable such successful socio-communicative adaptation are not well understood. The current results show sex-related differences in the cognitive profile of ASD individuals, which were diagnosed late in life exclusively. Higher verbal abilities were found in males (n = 69) as opposed to higher processing speed and better executive functions in females with ASD (n = 38). Since both sexes remained unidentified during childhood and adolescence, these results are suggestive for sex-distinctive cognitive strategies as an alternative to typically-developed reciprocal social behavior and social mimicry in high functioning ASD.

The influence of interpersonal synchrony and autism on impressions of dyadic interactions: a preregistered study / Irene S. PLANK in Molecular Autism, 16 (2025)  

Public ISBD [article]  inMolecular Autism > 16 (2025) . - 34 Titre : The influence of interpersonal synchrony and autism on impressions of dyadic interactions: a preregistered study Type de document : texte imprimé Auteurs : Irene S.

FALTER-WAGNER, Auteur Article en page(s) : 34 Langues : Anglais (eng) Mots-clés : Humans  Male  Autistic Disorder/psychology  Female  Adult  Interpersonal Relations  Young Adult  Eye Movements  Social Interaction  Middle Aged  Fixation, Ocular  Autism spectrum disorder  Behavioural coordination  Dyadic interactions  Impression formation  Interpersonal synchrony  Observed interactions  by the Ethics committee of the LMU Munich (Reference number: 23–0268) and  conducted in concordance with the Declaration of Helsinki. All participants were  informed of the study procedure, study aim, associated risks and benefits as well  as data processing and data protection, before they signed a written consent  form. Consent for publication: We received consent for publication from the two  interaction partners depicted in Fig. 2. Competing interests: The authors declare  no competing interests. Index. décimale : PER Périodiques Résumé : BACKGROUND: Humans form almost instantaneous impressions of everyone they encounter. These impressions set the first tone for how they approach and interact with others. Research on impression formation unveiled that impressions formed by autistic and non-autistic people are often less favourable when rating an autistic person. This effect is partly explainable by differences in motion dynamics. METHODS: In this preregistered study, we systematically assessed impressions formed by 27 autistic and 36 non-autistic comparison observers when watching videos showing silent interactions between either two non-autistic or between an autistic and a non-autistic person. We used an eye tracker to capture their gaze patterns while observing these interactions. Of each dyadic interaction, video vignettes with high and vignettes with low interpersonal synchrony of movement (IPS(mov)) were extracted using Motion Energy Analysis so that we could investigate the effects of interpersonal synchrony and diagnosis, respectively. RESULTS: Interactions were rated less favourably when the observed dyad included an autistic adult. Additionally, interactions showing low IPS(mov) were rated less favourably than interactions showing high IPS(mov), regardless of dyad type. Both autistic and comparison observers rated interactions of non-autistic dyads and high IPS(mov) interactions more favourably. Gaze patterns revealed differences between autistic and comparison observers, but no differences due to IPS(mov) or dyad type. Furthermore, dwell times to hands predicted ratings. LIMITATIONS: In this study, we investigated specific influences on impression formation, specifically interpersonal synchrony of movement and autism. There are many more potentially interesting aspects of individuals that impact impression formation, such as facial expressiveness, gaze behaviour and linguistic content of conversations, which should be investigated systematically and in a controlled fashion in future research. CONCLUSIONS: Extending research on autism and impression formation to dyadic interactions, this study reveals that motion dynamics play a role in how pleasant interactions are perceived. Autistic-involved interactions were rated lower, despite observers being unaware of the dyad type and only watching people's outlines. Future research should identify conversational aspects driving lower ratings of mixed dyads, potentially considering the effect of hand dwell times on ratings. Autistic and comparison observers showed different gaze patterns despite similar ratings, confirming distinct social information processing.
