Autistic Children Quickly Orient Away from Both Eyes and Mouths During Face Observation / Lilja Kristin JONSDOTTIR in Journal of Autism and Developmental Disorders, 53-1 (January 2023)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 53-1 (January 2023) . - p.495-502 Titre : Autistic Children Quickly Orient Away from Both Eyes and Mouths During Face Observation Type de document : texte imprimé Auteurs : Lilja Kristin JONSDOTTIR, Auteur ; Janina NEUFELD, Auteur ; Terje FALCK-YTTER, Auteur ; Johan LUNDIN KLEBERG, Auteur Article en page(s) : p.495-502 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Studies have supported two different hypotheses of reduced eye gaze in people with ASD; gaze avoidance and gaze indifference, while less is known about the role of anxiety. We tested these hypotheses using an eye-tracking paradigm that cued the eyes or mouth of emotional faces. Autistic children (n=12, mean age 7 years) looked faster away from both eyes and mouths than controls (n=22). This effect was not explained by anxiety symptoms. No difference was found in latency towards either area. These results indicate that attentional avoidance of autistic children is not specific to eyes, and that they do not show attentional indifference to eyes compared to controls. Atypicalities in visual scanning in ASD are possibly unrelated to specific facial areas.

A co-twin-control study of altered sensory processing in autism / Janina NEUFELD in Autism, 26-5 (July 2022)

Index. décimale : PER Périodiques Résumé : Individuals diagnosed with autism often describe that they process sensory information differently from others, and many experience sensory issues as problematic. For instance, an increased sensitivity to smells or sounds can make participating in social settings challenging. While sensory issues are now part of the diagnostic criteria for autism, they also co-occur with other psychiatric diagnoses such as attention deficit hyperactivity disorder and anxiety disorders. It is unclear to what extent the relationship between autism and alterations in sensory processing are due to genetics or environment. In addition, more research is needed on how autism, as compared to other diagnoses, is associated with sensory issues. Using a twin study, we found that genetic factors influenced self-reported reactivity to sensory stimuli in autism while environmental factors influenced other sensory issues (e.g. difficulties in detecting or differentiating sensory input). Hence, sensory hyper-reactivity might be an early onset core feature of autism, while other domains of alterations in sensory processing might develop later, influenced by the environment. Moreover, autism was more strongly associated with sensory issues related to increased sensitivity/reactivity as compared to other psychiatric diagnoses. However, attention deficit hyperactivity disorder was more strongly related to deficits in detecting/differentiating sensory stimuli and with an increased drive to seek sensory input. Our results indicate that sensory issues are not specific to autism, but that some aspects of altered sensory processing are more relevant for autism than for other diagnoses.

Does Camouflaging Cause Reduced Quality of Life? A Co-Twin Control Study / Karl Lundin REMNÉLIUS in Journal of Autism and Developmental Disorders, 56-2 (February 2026)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 56-2 (February 2026) . - p.709-721 Titre : Does Camouflaging Cause Reduced Quality of Life? A Co-Twin Control Study Type de document : texte imprimé Auteurs : Karl Lundin REMNÉLIUS, Auteur ; Janina NEUFELD, Auteur ; Johan ISAKSSON, Auteur ; Sven BÖLTE, Auteur Article en page(s) : p.709-721 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Camouflaging has been proposed to have a detrimental effect on quality of life, yet previous research has not accounted sufficiently for potential confounding by genetic and shared environmental factors. The current study utilized a co-twin control design providing stringent control for a range of confounders to investigate the hypothesis that camouflaging autistic traits has a negative impact on quality of life. The sample included 140 individual twins from 42 monozygotic (MZ) and 28 dizygotic (DZ) twin-pairs, enriched for participants with neurodevelopmental conditions including 22 autistic participants. All twins provided self-reports of camouflaging and quality of life. Autistic participants and specifically autistic females displayed increased camouflaging behaviors compared to non-autistic participants. Across the sample, higher levels of camouflaging were associated with reduced quality of life, surviving adjustment for confounding effects of autistic traits, ADHD, sex, and age. Within DZ- as well as MZ-pairs, which provide the highest level of control for unmeasured confounders, twins who camouflaged more reported lower quality of life compared to their co-twins, consistent with a causal influence of camouflaging on quality of life. Our results strengthen previous claims purporting camouflaging behaviors as a risk factor for reduced quality of life.

Eating Problems in Autistic Females and Males: A Co-twin Control Study / Karl LUNDIN REMNÉLIUS in Journal of Autism and Developmental Disorders, 52-7 (July 2022)

Index. décimale : PER Périodiques Résumé : This study investigated the association between autism and self-reported eating problems and the influence of gender on the association, in a sample of adolescent and adult twins (N=192). Autistic traits and autism diagnosis were associated with both total and specific eating problems, including selective eating and sensory sensitivity during mealtimes. Interaction effects indicated a stronger association between autistic traits and total eating problems in females, as well as more difficulties with eating in social contexts among autistic females. In within-pair analyses, where unmeasured confounders including genes and shared environment are implicitly controlled for, the association was lost within monozygotic pairs, which might further indicate a genetic influence on the relationship between autism and eating problems.
