Communicative intentions in autism spectrum disorder / Magdalena SCHÜTZ in Research in Autism Spectrum Disorders, 79 (November 2020)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 79 (November 2020) . - 101666 Titre : Communicative intentions in autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Magdalena SCHÜTZ, Auteur ; Angela CIARAMIDARO, Auteur ; Anne MARTINELLI, Auteur ; Ramona ÖLLER, Auteur ; Daniela HARTMANN, Auteur ; Grit HEIN, Auteur ; Vassil IOTZOV, Auteur ; Livia COLLE, Auteur ; Cristina BECCHIO, Auteur ; Henrik WALTER, Auteur ; Christine M. FREITAG, Auteur Article en page(s) : 101666 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  fMRI  Intention  Communication  Social interaction Index. décimale : PER Périodiques Résumé : Background Deficits in social communication and interaction are among the core symptoms of Autism Spectrum Disorder (ASD). Intention understanding in particular has been shown to be impaired in ASD. However, only one previous study has explicitly assessed the understanding of communicative intentions in ASD. Thus, the aim of the present study was to compare neural activation during the observation of communicative and non-communicative actions in participants with ASD and typically developing (TD) controls using functional magnetic resonance imaging (fMRI). Based on recent findings that show that the degree of involvement of the observer has an impact on neural activation, the present study included first- and third-person perspective stimuli. Method Twenty-five male TD (mean age 20.41?±?3.39) and twenty-two male participants with ASD (mean age 18.60?±?3.55) were included. Stimuli consisted of videos in which actors performed an action with an everyday object. Actions were either private or communicative; communicative actions were either directed at the observer (first-person) or at a third person. Results The ASD group showed reduced activation in the human middle temporal complex (hMT+) across all conditions. However, modulation of activation in response to different conditions remained intact in ASD. Additionally, while TD showed an increase in premotor cortex (PMC) activation in response to communicative actions directed at them, the ASD group showed a decrease in activation. Conclusions These findings suggest an early processing deficit with regard to human biological motion in ASD. Furthermore, results reflect a reduced preparedness for social interactions in ASD compared to TD when addressed directly.

Executive and Visuo-motor Function in Adolescents and Adults with Autism Spectrum Disorder / Michael SACHSE in Journal of Autism and Developmental Disorders, 43-5 (May 2013)

ASD individuals showed impaired spatial working memory, whereas planning, cognitive flexibility, and inhibition were spared. Pure movement execution during visuo-motor information processing also was intact. In contrast, execution time of reading, naming, and of visuo-motor information processing tasks including a choice component was increased in the ASD group. Results of this study are in line with previous studies reporting only minimal EF difficulties in older individuals with ASD when assessed by computerized tasks. The finding of impaired visuo-motor information processing should be accounted for in further neuropsychological studies in ASD.

However, to date, most of these studies have been cross-sectional, limiting the ability to make long-term inferences, given that most cortical structures continue to develop through adolescence. Methods Here, we used a subset of the IMAGEN population cohort sample (N = 502; assessment ages: 14, 19, and 22 years; mean age: 21.945 years; SD = 0.610) to understand longitudinally the long-term interrelations between stress, cortical development, and cognitive functioning. To these ends, we first used a latent change score model to examine four bivariate relations assessing individual differences in change in the relations between adolescent stress exposure and volume, surface area, and cortical thickness of cortical structures, as well as cognitive outcomes. Second, we probed for indirect neurocognitive effects linking stress to cortical brain structures and cognitive functions using rich longitudinal mediation modeling. Results Latent change score modeling showed that greater baseline adolescence stress at age 14 predicted a small reduction in the right anterior cingulate volume (Std. = .327, p = .042, 95% CI [ 0.643, 0.012]) and right anterior cingulate surface area (Std. = .274, p = .038, 95% CI [ 0.533, 0.015]) across ages 14 22. These effects were very modest in nature and became nonsignificant after correcting for multiple comparisons. Our longitudinal analyses found no evidence of indirect effects in the two neurocognitive pathways linking adolescent stress to brain and cognitive outcomes. Conclusion Findings shed light on the impact of stress on brain reductions, particularly in the prefrontal cortex that have consistently been implicated in the previous cross-sectional studies. However, the magnitude of effects observed in our study is smaller than that has been reported in past cross-sectional work. This suggests that the potential impact of stress during adolescence on brain structures may likely be more modest than previously noted.
