Absence of sex differences in mental rotation performance in autism spectrum disorder / Melanie S. ROHDE in Autism, 22-7 (October 2018)  

Public ISBD [article]  inAutism > 22-7 (October 2018) . - p.855-865 Titre : Absence of sex differences in mental rotation performance in autism spectrum disorder Type de document : texte imprimé Auteurs : Melanie S. ROHDE, Auteur ; Alexandra Livia GEORGESCU, Auteur ; Kai VOGELEY, Auteur ; Rolf FIMMERS, Auteur ; Christine M. FALTER-WAGNER, Auteur Article en page(s) : p.855-865 Langues : Anglais (eng) Mots-clés : adults  autism spectrum disorders  extreme male brain  mental rotation  sex differences  visuo-spatial Index. décimale : PER Périodiques Résumé : Mental rotation is one of the most investigated cognitive functions showing consistent sex differences. The 'Extreme Male Brain' hypothesis attributes the cognitive profile of individuals with autism spectrum disorder to an extreme version of the male cognitive profile. Previous investigations focused almost exclusively on males with autism spectrum disorder with only limited implications for affected females. This study is the first testing a sample of 12 female adults with high-functioning autism spectrum disorder compared to 14 males with autism spectrum disorder, 12 typically developing females and 14 typically developing males employing a computerised version of the mental rotation test. Reaction time and accuracy served as dependent variables. Their linear relationship with degree of rotation allows separation of rotational aspects of the task, indicated by slopes of the psychometric function, and non-rotational aspects, indicated by intercepts of the psychometric function. While the typical and expected sex difference for rotational task aspects was corroborated in typically developing individuals, no comparable sex difference was found in autism spectrum disorder individuals. Autism spectrum disorder and typically developing individuals did not differ in mental rotation performance. This finding does not support the extreme male brain hypothesis of autism.

Acquisition and Use of 'Priors' in Autism: Typical in Deciding Where to Look, Atypical in Deciding What Is There / Fredrik ALLENMARK in Journal of Autism and Developmental Disorders, 51-10 (October 2021)

This study examined whether this applies to decisions of attention allocation, of relevance for 'predictive-coding' accounts of ASD. In a visual search task, a salient but task-irrelevant distractor appeared with higher probability in one display half. Individuals with ASD learned to avoid 'attentional capture' by distractors in the probable region as effectively as control participants-indicating typical priors for deploying attention. However, capture by a 'surprising' distractor at an unlikely location led to greatly slowed identification of a subsequent target at that location-indicating that individuals with ASD attempt to control surprise (unexpected attentional capture) by over-regulating parameters in post-selective decision-making.

Adults with autism spectrum condition have atypical perception of ambiguous figures when bottom-up and top-down interactions are incongruous / M. INTAITE in Autism, 23-5 (July 2019)  

Public ISBD [article]  inAutism > 23-5 (July 2019) . - p.1133-1142 Titre : Adults with autism spectrum condition have atypical perception of ambiguous figures when bottom-up and top-down interactions are incongruous Type de document : texte imprimé Auteurs : M.

The perception of the ambiguous figure was manipulated by adaptation to unambiguous figures and/or by placing the ambiguous figure into a context of unambiguous figures. This resulted in four conditions testing the independent and combined (congruent and incongruent) manipulations of adaptation (bottom-up) and spatial context (top-down) effects. The strength of perception, as measured by perception of the first reported orientation of the ambiguous stimulus, was affected comparably between groups. Nevertheless, the strength of perception, as measured by perceptual durations, was affected differently between groups: the perceptual effect was strongest for the autistic spectrum condition group when combined bottom-up and top-down conditions were congruent. In contrast, the strength of the perceptual effect in response to the same condition in the typical adults group was comparable to the adaptation, but stronger than both the context and the incongruent combined bottom-up and top-down conditions. Furthermore, the context condition was stronger than the incongruent combined bottom-up and top-down conditions for the typical adults group. Thus, our findings support the view of stimulus-specific top-down modulation in autistic spectrum condition.

Autism traits outweigh alexithymia traits in the explanation of mentalising performance in adults with autism but not in adults with rejected autism diagnosis / Christine M. FALTER-WAGNER in Molecular Autism, 13 (2022)  

Public ISBD [article]  inMolecular Autism > 13 (2022) . - 32 p. Titre : Autism traits outweigh alexithymia traits in the explanation of mentalising performance in adults with autism but not in adults with rejected autism diagnosis Type de document : texte imprimé Auteurs : Christine M. FALTER-WAGNER, Auteur ; Carola BLOCH, Auteur ; Lana BURGHOF, Auteur ; Fritz-Georg LEHNHARDT, Auteur ; Kai VOGELEY, Auteur Article en page(s) : 32 p. Langues : Anglais (eng) Mots-clés : Adult  Affective Symptoms/complications  Autism Spectrum Disorder/psychology  Autistic Disorder/psychology  Cross-Sectional Studies  Humans  Phenotype  Alexithymia  Autism  Dominance analysis  Mentalising Index. décimale : PER Périodiques Résumé : BACKGROUND: Pronounced alexithymia traits have been found in autism spectrum disorder (ASD) and recent research has been carving out the impact alexithymia traits might have on mentalising deficits associated with ASD. METHOD: In this cross-sectional study, a large representative referral population for diagnostic examination for possible ASD (n=400) was screened for clinical alexithymia with a German version of the Reading the Mind in the Eyes test (RME). In contrast to previous attempts to carve out the impact of alexithymia traits on mentalising deficits though, we employed dominance analysis to account for the correlation between predictors. The relative relationship between alexithymia traits and autism traits with RME performance was investigated in the group of individuals with confirmed ASD diagnosis (N=281) and compared to the clinical referral sample in which ASD was ruled out (N=119). RESULTS: Dominance analysis revealed autism traits to be the strongest predictor for reduced mentalising skills in the ASD sample, whereas alexithymia contributed significantly less. In the sample of individuals with ruled out diagnosis, autism traits were the strongest predictor, but alexithymia traits were in sum equally associated to mentalising, with the External-Oriented Thinking subscale as an important predictor of this association. LIMITATIONS: It needs to be considered that the cross-sectional study design does not allow for causal inference. Furthermore, mentalising is a highly facetted capacity and measurements need to reduce this complexity into simple quantities which limits the generalizability of results. DISCUSSION: While alexithymia traits should be considered for their mental health importance, they do not dominate the explanation of reduced mentalising skills in individuals with ASD, but they might do to a larger degree in individuals with ruled out ASD.

Brief Report: Social Anxiety in Autism Spectrum Disorder is Based on Deficits in Social Competence / J. ESPELÖER in Journal of Autism and Developmental Disorders, 51-1 (January 2021)

Employing two questionnaires (SASKO; IU), individuals with ASD (n = 23) showed increased scores of SOCIAL ANXIETY (SASKO) and of INTOLERANCE OF UNCERTAINTY (IU), compared to a non-clinical comparison group (NC; n = 25). SOCIAL ANXIETY scores were equally increased for ASD and a reference population of individuals with social anxiety disorder (SAD; n = 68). However, results showed increased SOCIAL COMPETENCE DEFICITS in ASD compared to SAD and NC groups. This study allows drawing the conclusion that social anxiety symptoms in ASD can be traced back to autism-specific deficits in social skills and are therefore putatively based on different, substantially "deeper" implemented cognitive mechanisms.
