However, previous laboratory-based sensory psychophysical studies that have aimed to investigate olfactory sensitivity in children with ASD have produced inconsistent results. The methodology of these studies is limited by several factors, and more sophisticated approaches are required to produce consistent results. METHODS: We measured olfactory detection thresholds in children with ASD and typical development (TD) using a pulse ejection system-a newly developed methodology designed to resolve problems encountered in previous studies. The two odorants used as stimuli were isoamyl acetate and allyl caproate. RESULTS: Forty-three participants took part in this study: 23 (6 females, 17 males) children with ASD and 20 with TD (6 females, 14 males). Olfactory detection thresholds of children with ASD were significantly higher than those of TD children with both isoamyl acetate (2.85 +/- 0.28 vs 1.57 +/- 0.15; p < 0.001) and allyl caproate ( 3.30 +/- 0.23 vs 1.17 +/- 0.08; p < 0.001). CONCLUSIONS: We found impaired olfactory detection thresholds in children with ASD. Our results contribute to a better understanding of the olfactory abnormalities that children with ASD experience. Considering the role and effect that odors play in our daily lives, insensitivity to some odorants might have a tremendous impact on children with ASD. Future studies of olfactory processing in ASD may reveal important links between brain function, clinically relevant behavior, and treatment.

A cross-cultural examination of bi-directional mentalising in autistic and non-autistic adults / Bianca A. SCHUSTER in Molecular Autism, 16 (2025)

Although this idea has grown in popularity over recent years, there is currently only limited empirical evidence to support mismatch theories. Moreover, the social model of disability such theories are grounded in demands a culturally situated view of social interaction, yet research on mentalising and/or autism is largely biased towards Western countries, with little knowledge on how successful mentalising is defined differently, and how tools to assess socio-cognitive ability compare, across cultures. METHODS: Using a widely employed mentalising task-the animations task-, the current study investigated and compared the bi-directional mentalising performance of British and Japanese autistic and non-autistic adults and assessed observer-agent kinematic similarity as a potential dimension along which mismatches may occur between neurotypes. Participants were asked to depict various mental state- and action-based interactions by moving two triangles across a touch-screen device before viewing and interpreting stimuli generated by other participants. RESULTS: In the UK sample, our results replicate a seminal prior study in showing poorer mentalising abilities in non-autistic adults for animations generated by the autistic group. Crucially, the same pattern did not emerge in the Japanese sample, where there were no mentalising differences between the two groups. LIMITATIONS: Limitations of the current study include that efforts to match all samples within and across cultures in terms of IQ, gender, and age were not successful in all comparisons, but control analyses suggest this did not affect our results. Furthermore, any performance differences were found for both the mental state- and action-based conditions, mirroring prior work and raising questions about the domain-specificity of the employed task. CONCLUSIONS: Our results add support for a paradigm shift in the autism literature, moving beyond deficit-based models and towards acknowledging the inherently relational nature of social interaction. We further discuss how our findings suggest limited cultural transferability of common socio-cognitive measures rather than superior mentalising abilities in Japanese autistic adults, underscoring the need for more cross-cultural research and the development of culturally sensitive scientific and diagnostic tools.

Developmental changes in attention to social information from childhood to adolescence in autism spectrum disorders: a comparative study / Toru FUJIOKA in Molecular Autism, 11 (2020)

Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Developmental change  Eye-tracking  Social information Index. décimale : PER Périodiques Résumé : BACKGROUND: Elucidating developmental changes in the symptoms of autism spectrum disorder (ASD) is important to support individuals with ASD. However, no report has clarified the developmental changes in attention to social information for a broad age range. The aim of this study was to investigate the developmental changes in attention to social information from early childhood to adolescence in individuals with ASD and typically developed (TD) children. METHODS: We recruited children with ASD (n = 83) and TD participants (n = 307) between 2 and 18 years of age. Using the all-in-one-eye-tracking system, Gazefinder, we measured the percentage fixation time allocated to areas of interest (AoIs) depicted in movies (the eyes and mouth in movies of a human face with/without mouth motion, upright and inverted biological motion in movies showing these stimuli simultaneously, people and geometry in preference paradigm movies showing these stimuli simultaneously, and objects with/without finger-pointing in a movie showing a woman pointing toward an object). We conducted a three-way analysis of variance, 2 (diagnosis: ASD and TD) by 2 (sex: male and female) by 3 (age group: 0-5, 6-11, and 12-18 years) and locally weighted the scatterplot smoothing (LOESS) regression curve on each AoI. RESULTS: In the face stimuli, the percentage fixation time to the eye region for the TD group increased with age, whereas the one for the ASD group did not. In the ASD group, the LOESS curves of the gaze ratios at the eye region increased up to approximately 10 years of age and thereafter tended to decrease. For the percentage fixation time to the people region in the preference paradigm, the ASD group gazed more briefly at people than did the TD group. LIMITATIONS: It is possible that due to the cross-sectional design, the degree of severity and of social interest might have differed according to the subjects' age. CONCLUSIONS: There may be qualitative differences in abnormal eye contact in ASD between individuals in early childhood and those older than 10 years.

Differential amygdala response to lower face in patients with autistic spectrum disorders: An fMRI study / Makoto ISHITOBI in Research in Autism Spectrum Disorders, 5-2 (April-June 2011)

Most of these findings were obtained from studies using tasks related to whole faces. However, individuals with ASD tend to rely more on individual parts of the face for identification than on the overall configuration. Therefore, this neuroimaging evidence might reflect differential visual attention systems in face recognition. It was hypothesized that differential brain function is shown between ASD and control participants with face recognition tasks presenting parts of faces separately. Nine adults with high-functioning ASD and 24 age-matched normal comparison participants were studied using a 3T-MR scanner. We investigated brain activation when processing whole faces and parts of faces displaying positive or negative expressions. The control group showed bilateral amygdalae activation to the whole face, but not to parts of the face. The ASD group showed bilateral amygdalae activation to the lower face (mainly mouth region), but not to the whole face and upper face (mainly eye region). These findings suggest that differential amygdala function for face processing exists in ASD. This aberrant amygdala function might cause abnormalities in gaze processing or recognition of emotional expressions, shown clinically in ASD.
