Alexithymia, but not autism spectrum disorder, may be related to the production of emotional facial expressions / D. A. TREVISAN in Molecular Autism, 7 (2016)  

Public ISBD [article]  inMolecular Autism > 7 (2016) . - 46p.

TREVISAN, Auteur ; M. BOWERING, Auteur ; Elina BIRMINGHAM, Auteur Article en page(s) : 46p. Langues : Anglais (eng) Mots-clés : Adolescent  Affective Symptoms/physiopathology/psychology  Autism Spectrum Disorder/classification/physiopathology/psychology  Case-Control Studies  Child  Facial Expression  Female  Humans  Male  Pattern Recognition, Automated/statistics & numerical data  Social Perception  Software  Alexithymia  Autism  Facial expressions Index. décimale : PER Périodiques Résumé : BACKGROUND: A prominent diagnostic criterion of autism spectrum disorder (ASD) relates to the abnormal or diminished use of facial expressions. Yet little is known about the mechanisms that contribute to this feature of ASD. METHODS: We showed children with and without ASD emotionally charged video clips in order to parse out individual differences in spontaneous production of facial expressions using automated facial expression analysis software. RESULTS: Using hierarchical multiple regression, we sought to determine whether alexithymia (characterized by difficulties interpreting one's own feeling states) contributes to diminished facial expression production. Across groups, alexithymic traits-but not ASD traits, IQ, or sex-were associated with quantity of facial expression production. CONCLUSIONS: These results accord with a growing body of research suggesting that many emotion processing abnormalities observed in ASD may be explained by co-occurring alexithymia. Developmental and clinical considerations are discussed, and it is argued that alexithymia is an important but too often ignored trait associated with ASD that may have implications for subtyping individuals on the autism spectrum.

Facial Expression Production in Autism: A Meta-Analysis / D. A. TREVISAN in Autism Research, 11-12 (December 2018)  

Public ISBD [article]  inAutism Research > 11-12 (December 2018) . - p.1586-1601 Titre : Facial Expression Production in Autism: A Meta-Analysis Type de document : Texte imprimé et/ou numérique Auteurs : D. A. TREVISAN, Auteur ; M. HOSKYN, Auteur ; Elina BIRMINGHAM, Auteur Article en page(s) : p.1586-1601 Langues : Anglais (eng) Mots-clés : autism  facial expressions  meta-analysis Index. décimale : PER Périodiques Résumé : This meta-analysis summarized studies that examined group differences on the production of facial expressions in participants with ASD compared to typically developing or nonautistic clinical comparison groups. The overall summary effect from 67 effect sizes representing the average ASD-comparison group differences in facial expressions was -0.481, indicating a moderate effect size. We conducted subgroup analyses to group effect sizes according to separate facial expression abilities identified in the literature. These analyses revealed that participants with ASD display facial expressions less frequently and for less amount of time, and they are less likely to share facial expressions with others or automatically mimic the expressions of real faces or face stimuli. Their facial expressions are also judged to be lower in quality and are expressed less accurately. However, participants with ASD do not express emotions less intensely, nor is their reaction time of expression onset slower in response to odors, startling sensations, or in response to face stimuli in mimicry studies. ASD-comparison group differences were moderated by matching procedures, age, and intellectual functioning of the ASD participants suggesting that persons with higher IQ and larger number of accumulated life experiences are better able to produce facial expressions that are more consistent with "neurotypical" norms. Group differences were also stronger for "covertly elicited" than "explicitly elicited" facial expressions suggesting individuals with ASD may naturally produce facial expressions differently from other populations, but are less impaired in expressing emotions typically when prompted to do so in a laboratory setting. Autism Research 2018, 11: 1586-1601. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: We reviewed studies that compared facial expressions in people with and without autism. Results revealed that facial expressions of people with autism are atypical in appearance and quality and are used atypically to regulate social interactions. The magnitude of these differences was influenced by participant characteristics (e.g. age and intellectual functioning), and by how facial expressions were measured and analyzed in various studies.

Interoceptive challenges in ASD remain under researched and poorly understood. In this study, we analyzed texts of adults who self-identify as autistic describing their interoceptive challenges. Many individuals described limited awareness of hunger, satiation, or thirst, which contributed to eating disordered behavior in some instances. Others described limited awareness or difficulty understanding affective arousal, pain or illness, and difficulty differentiating benign body signals from signals that represent medical concerns. Findings from this study call for increased research attention on this topic, and a need for valid and objective measures for assessing interoception in ASD.

Systematic review of factors that may influence the outcomes and generalizability of parent-mediated interventions for young children with autism spectrum disorder / D. TREMBATH in Autism Research, 12-9 (September 2019)  

Public ISBD [article]  inAutism Research > 12-9 (September 2019) . - p.1304-1321 Titre : Systematic review of factors that may influence the outcomes and generalizability of parent-mediated interventions for young children with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : D. TREMBATH, Auteur ; M. GURM, Auteur ; N. E. SCHEERER, Auteur ; D. A. TREVISAN, Auteur ; J. PAYNTER, Auteur ; Gal BOHADANA, Auteur ; J. ROBERTS, Auteur ; G. IAROCCI, Auteur Article en page(s) : p.1304-1321 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  caregiver-mediated  intervention  parent-mediated Index. décimale : PER Périodiques Résumé : Parent mediated interventions have the potential to positively influence the interactions and developmental outcomes of children with autism spectrum disorder (ASD). However, a range of factors relating to children, parents and caregivers, and study design may impact on outcomes and thus the generalizability of these interventions to the broader community. The objective of this review was to examine factors that may influence the feasibility, appropriateness, effectiveness, and generalizability of parent mediated interventions for children with ASD. We conducted a systematic review, yielding 41 articles. There was substantial variability in the intervention type, intensity, and study quality. Notably, 46 different inclusion/exclusion criteria were reported across studies including factors relating to children's development, access to other services, comorbidities, parental factors, and access to the intervention. Fifteen articles included examination of 45 different factors potentially associated with, or influencing, intervention outcomes including child (e.g., language skills, ASD severity, cognition) and parent (e.g., adherence and fidelity, education) factors. Although there is clear evidence for an increasingly sophisticated (e.g., systematic phased research for some interventions) and diverse (e.g., studies in geographical diverse contexts including low-resource communities) approach to research examining parent mediated interventions, there remains a need for improved study quality and measurement consistency in research, including a detailed examination of factors that may predict, moderate, and mediate intervention effectiveness for children and their parents. Autism Res 2019, 12: 1304-1321. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Parent mediated interventions-in which parents adapt their own behavior or deliver interventions to help their children learn-appear to be effective for some children with autism spectrum disorder. In this review, we identified a range of child, parent, and study design factors that may influence intervention outcomes and ultimately the uptake of these approaches in the community. We suggest that research in this area could be further improved by ensuring that studies include diverse groups of children and parents, and by using study designs that help to establish not only if interventions work, but for whom they work best and why.
