Can Neurotypical Individuals Read Autistic Facial Expressions? Atypical Production of Emotional Facial Expressions in Autism Spectrum Disorders / Rebecca BREWER in Autism Research, 9-2 (February 2016)

Atypical Production of Emotional Facial Expressions in Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Rebecca BREWER, Auteur ; Federica BIOTTI, Auteur ; Caroline CATMUR, Auteur ; Clare PRESS, Auteur ; Francesca HAPPE, Auteur ; Richard COOK, Auteur ; Geoffrey BIRD, Auteur Article en page(s) : p.262-271 Langues : Anglais (eng) Mots-clés : social cognition  face perception  cognitive neuroscience  expression production Index. décimale : PER Périodiques Résumé : The difficulties encountered by individuals with autism spectrum disorder (ASD) when interacting with neurotypical (NT, i.e. nonautistic) individuals are usually attributed to failure to recognize the emotions and mental states of their NT interaction partner. It is also possible, however, that at least some of the difficulty is due to a failure of NT individuals to read the mental and emotional states of ASD interaction partners. Previous research has frequently observed deficits of typical facial emotion recognition in individuals with ASD, suggesting atypical representations of emotional expressions. Relatively little research, however, has investigated the ability of individuals with ASD to produce recognizable emotional expressions, and thus, whether NT individuals can recognize autistic emotional expressions. The few studies which have investigated this have used only NT observers, making it impossible to determine whether atypical representations are shared among individuals with ASD, or idiosyncratic. This study investigated NT and ASD participants’ ability to recognize emotional expressions produced by NT and ASD posers. Three posing conditions were included, to determine whether potential group differences are due to atypical cognitive representations of emotion, impaired understanding of the communicative value of expressions, or poor proprioceptive feedback. Results indicated that ASD expressions were recognized less well than NT expressions, and that this is likely due to a genuine deficit in the representation of typical emotional expressions in this population. Further, ASD expressions were equally poorly recognized by NT individuals and those with ASD, implicating idiosyncratic, rather than common, atypical representations of emotional expressions in ASD.

Intact Facial Adaptation in Autistic Adults / Richard COOK in Autism Research, 7-4 (August 2014)  

Public ISBD [article]  inAutism Research > 7-4 (August 2014) . - p.481-490 Titre : Intact Facial Adaptation in Autistic Adults Type de document : Texte imprimé et/ou numérique Auteurs : Richard COOK, Auteur ; Rebecca BREWER, Auteur ; Punit SHAH, Auteur ; Geoffrey BIRD, Auteur Année de publication : 2014 Article en page(s) : p.481-490 Langues : Anglais (eng) Mots-clés : autism  adaptation  aftereffects  facial identity  facial expressions Index. décimale : PER Périodiques Résumé : Adaptation paradigms seek to bias subsequently viewed stimuli through prolonged exposure to an adapting stimulus, thereby giving rise to an aftereffect. Recent experiments have found that children with autism spectrum disorders (ASD) show reduced facial aftereffects, prompting some researchers to speculate that all individuals with ASD exhibit deficient facial adaptation. However, caution is required when generalizing findings from samples of children with ASD to the wider ASD population. The reduced facial aftereffects seen in child samples may instead reflect delayed or atypical developmental trajectories, whereby individuals with ASD are slower to develop adaptive mechanisms. In the present study, two experiments were conducted to determine whether high-functioning adults with ASD also show diminished aftereffects for facial identity and expression. In Experiment 1, using a procedure that minimized the contribution of low-level retinotopic adaptation, we observed substantial aftereffects comparable to those seen in matched controls, for both facial identity and expression. A similar pattern of results was seen in Experiment 2 using a revised procedure that increased the contribution of retinotopic adaptation to the facial aftereffects observed. That adults with autism can show robust facial aftereffects raises the possibility that group differences are seen only at particular points during development, and may not be a lifelong feature of the condition.

Non-autistic adults can recognize posed autistic facial expressions: Implications for internal representations of emotion / Andrew J. LAMPI in Autism Research, 16-7 (July 2023)  

Public ISBD [article]  inAutism Research > 16-7 (July 2023) . - p.1321-1334 Titre : Non-autistic adults can recognize posed autistic facial expressions: Implications for internal representations of emotion Type de document : Texte imprimé et/ou numérique Auteurs : Andrew J. LAMPI, Auteur ; Rebecca BREWER, Auteur ; Geoffrey BIRD, Auteur ; Vikram K. JASWAL, Auteur Article en page(s) : p.1321-1334 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Autistic people report that their emotional expressions are sometimes misunderstood by non-autistic people. One explanation for these misunderstandings could be that the two neurotypes have different internal representations of emotion: Perhaps they have different expectations about what a facial expression showing a particular emotion looks like. In three well-powered studies with non-autistic college students in the United States (total N=632), we investigated this possibility. In Study 1, participants recognized most facial expressions posed by autistic individuals more accurately than those posed by non-autistic individuals. Study 2 showed that one reason the autistic expressions were recognized more accurately was because they were better and more intense examples of the intended expressions than the non-autistic expressions. In Study 3, we used a set of expressions created by autistic and non-autistic individuals who could see their faces as they made the expressions, which could allow them to explicitly match the expression they produced with their internal representation of that emotional expression. Here, neither autistic expressions nor non-autistic expressions were consistently recognized more accurately. In short, these findings suggest that differences in internal representations of what emotional expressions look like are unlikely to play a major role in explaining why non-autistic people sometimes misunderstand the emotions autistic people are experiencing.
