Impaired Recognition of Basic Emotions from Facial Expressions in Young People with Autism Spectrum Disorder: Assessing the Importance of Expression Intensity / S. GRIFFITHS in Journal of Autism and Developmental Disorders, 49-7 (July 2019)

Titre : Impaired Recognition of Basic Emotions from Facial Expressions in Young People with Autism Spectrum Disorder: Assessing the Importance of Expression Intensity Type de document : Texte imprimé et/ou numérique Auteurs : S. GRIFFITHS, Auteur ; C. JARROLD, Auteur ; I. S. PENTON-VOAK, Auteur ; A. T. WOODS, Auteur ; A. L. SKINNER, Auteur ; M. R. MUNAFO, Auteur Article en page(s) : p.2768-2778 Langues : Anglais (eng) Mots-clés : Bias Emotion recognition Facial expression Intensity Online testing Perception Index. décimale : PER Périodiques Résumé : It has been proposed that impairments in emotion recognition in ASD are greater for more subtle expressions of emotion. We measured recognition of 6 basic facial expressions at 8 intensity levels in young people (6-16 years) with ASD (N = 63) and controls (N = 64) via an Internet platform. Participants with ASD were less accurate than controls at labelling expressions across intensity levels, although differences at very low levels were not detected due to floor effects. Recognition accuracy did not correlate with parent-reported social functioning in either group. These findings provide further evidence for an impairment in recognition of basic emotion in ASD and do not support the idea that this impairment is limited solely to low intensity expressions.

DAVIS, Auteur ; Bert UCHINO, Auteur Article en page(s) : p.1986-1996 Langues : Anglais (eng) Mots-clés : romantic relationships blood pressure adolescence intensity Index. décimale : PER Périodiques Résumé : Intensity in adolescent romantic relationships was examined as a long-term predictor of higher adult blood pressure in a community sample followed from age 17 to 31 years. Romantic intensity in adolescence “ measured via the amount of time spent alone with a partner and the duration of the relationship “ was predicted by parents’ psychologically controlling behavior and was in turn found to predict higher resting adult systolic and diastolic blood pressure even after accounting for relevant covariates. The prediction to adult blood pressure was partially mediated via conflict in nonromantic adult friendships and intensity in adult romantic relationships. Even after accounting for these mediators, however, a direct path from adolescent romantic intensity to higher adult blood pressure remained. Neither family income in adolescence nor trait measures of personality assessed in adulthood accounted for these findings. The results of this study are interpreted both as providing further support for the view that adolescent social relationship qualities have substantial long-term implications for adult health, as well as suggesting a potential physiological mechanism by which adolescent relationships may be linked to adult health outcomes.

In order to maximize the accessibility and cost-effectiveness of its services, a regional public agency serving children with ASD implemented two consecutive programs: a 1 year pre-program for parents (intensive sessions followed by 1 hour per week of individual coaching) and an early behavioral intervention (EBI) program with less than optimal weekly intensity (16–20 hours) delivered in mainstream day care settings. The outcomes of these programs were assessed among 93 children. Their IQ, adaptive behavior, and socioaffective competencies were found to have improved after 12 months in the EBI program. Their autism symptoms had also decreased marginally. Although the pre-program did not have observable effects on children's outcomes, their parents reported positive impact on their well-being and family life. These results demonstrate the feasibility and sustainability of offering EBI to large, unselected populations. However, the pre-program may need to be offered more intensively in order to yield positive outcomes for children. Delivering EBI services in mainstream settings may foster the development of skills linked to social integration.

Langues : Anglais (eng) Mots-clés : Adult Autism Spectrum Disorder/physiopathology/psychology Differential Threshold/physiology Emotions/physiology Female Humans Hyperesthesia/etiology/physiopathology/psychology Hypesthesia/etiology/physiopathology/psychology Male Odorants Olfactory Pathways/physiopathology Olfactory Perception/physiology Pleasure Recognition (Psychology)/physiology Sensory Thresholds Young Adult Autism spectrum disorders Hyperresponsiveness Identification Intensity Olfaction Pleasantness Suprathreshold detection Index. décimale : PER Périodiques Résumé : BACKGROUND: As evidenced in the DSM-V, autism spectrum disorders (ASD) are often characterized by atypical sensory behavior (hyper- or hypo-reactivity), but very few studies have evaluated olfactory abilities in individuals with ASD. METHODS: Fifteen adults with ASD and 15 typically developing participants underwent olfactory tests focused on superficial (suprathreshold detection task), perceptual (intensity and pleasantness judgment tasks), and semantic (identification task) odor processing. RESULTS: In terms of suprathreshold detection performance, decreased discrimination scores and increased bias scores were observed in the ASD group. Furthermore, the participants with ASD exhibited increased intensity judgment scores and impaired scores for pleasantness judgments of unpleasant odorants. Decreased identification performance was also observed in the participants with ASD compared with the typically developing participants. This decrease was partly attributed to a higher number of near misses (a category close to veridical labels) among the participants with ASD than was observed among the typically developing participants. CONCLUSIONS: The changes in discrimination and bias scores were the result of a high number of false alarms among the participants with ASD, which suggests the adoption of a liberal attitude in their responses. Atypical intensity and pleasantness ratings were associated with hyperresponsiveness and flattened emotional reactions, respectively, which are typical of participants with ASD. The high number of near misses as non-veridical labels suggested that categorical processing is functional in individuals with ASD and could be explained by attention-deficit/hyperactivity disorder. These findings are discussed in terms of dysfunction of the olfactory system.

Eighteen children with predominantly intellectual low-functioning ASD (LFA, IQ <80) and two control groups (mental and chronological age matched), were assessed for their ability to classify emotional faces, of high, medium and low intensities, as happy or angry. For anger, the LFA group made more errors for lower intensity expressions than the control groups, classifications did not differ for happiness. This is the first study to find that the LFA group made more across-valence errors than controls. These data are consistent with atypical facial expression processing in ASD being associated with differences in the structure of emotion categories.
