Biological motion perception in autism spectrum disorder: a meta-analysis / Greta Krasimirova TODOROVA in Molecular Autism, 10 (2019)  

Public ISBD [article]  inMolecular Autism > 10 (2019) . - 49 p. Titre : Biological motion perception in autism spectrum disorder: a meta-analysis Type de document : texte imprimé Auteurs : Greta Krasimirova TODOROVA, Auteur ; Rosalind Elizabeth Mcbean HATTON, Auteur ; Frank E. POLLICK, Auteur Article en page(s) : 49 p. Langues : Anglais (eng) Mots-clés : Age  Autism spectrum disorders  Biological motion  Emotion recognition  Meta-analysis Index. décimale : PER Périodiques Résumé : Background: Biological motion, namely the movement of others, conveys information that allows the identification of affective states and intentions. This makes it an important avenue of research in autism spectrum disorder where social functioning is one of the main areas of difficulty. We aimed to create a quantitative summary of previous findings and investigate potential factors, which could explain the variable results found in the literature investigating biological motion perception in autism. Methods: A search from five electronic databases yielded 52 papers eligible for a quantitative summarisation, including behavioural, eye-tracking, electroencephalography and functional magnetic resonance imaging studies. Results: Using a three-level random effects meta-analytic approach, we found that individuals with autism generally showed decreased performance in perception and interpretation of biological motion. Results additionally suggest decreased performance when higher order information, such as emotion, is required. Moreover, with the increase of age, the difference between autistic and neurotypical individuals decreases, with children showing the largest effect size overall. Conclusion: We highlight the need for methodological standards and clear distinctions between the age groups and paradigms utilised when trying to interpret differences between the two populations.

This study tests intention perception in ASD via animacy stimuli derived from human motion. Using a forced choice task, 28 participants (14 ASDs; 14 age and verbal-I.Q. matched controls) categorized displays of Chasing, Fighting, Flirting, Following, Guarding and Playing, from two viewpoints (side, overhead) in both animacy and full video displays. Detailed analysis revealed no differences between populations in accuracy, or response patterns. Collapsing across groups revealed Following and Video displays to be most accurately perceived. The stimuli and intentions used are compared to those of previous studies, and the implication of our results on the understanding of Theory of Mind in ASD is discussed.

The world is nuanced but pixelated: Autistic individuals? perspective on HIPPEA / Rosalind Elizabeth Mcbean HATTON ; Sarveen SADIQUE ; Frank E. POLLICK in Autism, 28-2 (February 2024)  

Public ISBD [article]  inAutism > 28-2 (February 2024) . - p.498?509 Titre : The world is nuanced but pixelated: Autistic individuals? perspective on HIPPEA Type de document : texte imprimé Auteurs : Rosalind Elizabeth Mcbean HATTON, Auteur ; Sarveen SADIQUE, Auteur ; Frank E. POLLICK, Auteur Article en page(s) : p.498?509 Mots-clés : autism  HIPPEA  hybrid thematic analysis Index. décimale : PER Périodiques Résumé : Little attention has been given to the voice of autistic individuals during the development of theories that are trying to explain the condition. This can often make individuals feel that they have to fit into the theory?s definition, rather than it fitting into their experience. We aimed to understand to what extent the HIPPEA (High, Inflexible Precision of Prediction Errors in Autism) theory resonates with the lived experiences of autistic individuals. We conducted 21 questionnaires and 8 follow-up interviews and used a hybrid (deductive and inductive) approach to analyse the data. Based on the participants? views, HIPPEA provides an explanation for many of the lived experiences of autistic individuals. However, refinement is needed with respect to interpersonal interactions, emotional processing and individuals? motivation to engage with their environment despite challenges with the way the world is organised. Furthermore, more details are needed for the theory to accurately allow us to understand autism. Lay Abstract Autism is a condition comprised of difficulties in social and communication contexts, sensory sensitivities as well as restrictive and repetitive behaviours. Many theories have tried to explain all the symptoms and behaviours associated with autism. We focus on one recent theory ? High, Inflexible Precision of Prediction Errors in Autism (HIPPEA). We aim to understand how much this theory fits the experiences of autistic individuals. We collected data through 21 online questionnaires and 8 follow-up interviews. One of our participants was a parent of an autistic child, and the remaining were adults who reported a diagnosis of autism. We analysed the data by thinking about how it fitted with what we already knew and by looking for new insights which came up. Our results suggest that autistic individuals can make generalisations but that this happens more slowly across both social and non-social areas. These generalisations are very reliant on detail ? in computer terms, they are ?pixelated?. This is in line with what HIPPEA suggests. We also showed that autistic individuals can be motivated to explore and engage socially, something that needs more consideration within HIPPEA. Overall, this study shows that HIPPEA can explain many autistic experiences, but that further refinement is needed.
