The gap between IQ and adaptive functioning in autism spectrum disorder: Disentangling diagnostic and sex differences / G. A. MCQUAID in Autism, 25-6 (August 2021)

Index. décimale : PER Périodiques Résumé : Adaptive functioning refers to skills that are vital to success in day-to-day life, including daily living (e.g. grocery shopping, food preparation, transportation use), communication (e.g. verbal expression of needs), and socialization skills (e.g. interpersonal skills, including expressing and recognizing emotions, and understanding turn-taking in conversation). Among autistic individuals without intellectual disability, adaptive functioning is not commensurate with intellectual ability (IQ), and instead a gap exists between these individuals' intellectual ability and their adaptive skills. Further, these autistic individuals show a widening of this gap with increasing age. Existing studies of the gap between IQ and adaptive functioning have studied predominantly male samples. Thus, we do not know if the gap also exists in autistic females. We therefore looked at adaptive functioning and the gap between IQ and adaptive functioning in a large sample of autistic girls and boys without intellectual disability. To disentangle effects of group (autistic vs typically developing) from effects of sex (girls vs boys), we compared autistic girls and boys to one another as well as to their same-sex typically developing peers. Analyses took into consideration differences in IQ between autistic and typically developing youth. We found autistic girls, like autistic boys, show lower adaptive functioning than their same-sex typically developing peers. Results underscore the need to evaluate adaptive functioning in autistic individuals without intellectual disability and to provide necessary supports. The large gap between intellectual ability and socialization skills, in particular, may be of critical importance in improving our understanding of outcomes and mental health difficulties among autistic females.

[article]
Titre : Theory of mind performance in younger and older adults with elevated autistic traits Type de document : Texte imprimé et/ou numérique Auteurs : Gavin R. STEWART, Auteur ; Gregory L. WALLACE, Auteur ; Martha COTTAM, Auteur ; Rebecca A. CHARLTON, Auteur Article en page(s) : p.751-762 Langues : Anglais (eng) Mots-clés : adulthood aging autism broad autism phenotype theory of mind Index. décimale : PER Périodiques Résumé : Little is known about the impact of aging with Autism Spectrum Disorder on theory of mind (ToM). While ToM difficulties appear to abate with age in older autistic populations, this has yet to be explored in the Broad Autism Phenotype (BAP). The current study examined ToM performance among younger (n = 49, aged 18-46) and older adults (n = 47, aged 60-91) who were classified as on the BAP (younger n = 18; older n = 21) or not (younger n = 31; older n = 26) using the BAP Questionnaire. ToM was assessed using the ecologically valid Strange Stories Film Task (SSFT) and the dynamic Happe-Frith Triangle Animations task (TA). A 2 x 2 analysis of variance examined the effects of autistic traits (BAP vs. non-BAP) and age (young vs. old). For both SSFT and TA, results showed autistic trait main effects on task performance (non-BAP > BAP). Age main effects were observed for some but not all metrics on TA (younger better than older), with no differences in SSFT. An interaction of autistic traits and age was observed in TA Intentionality, with younger non-BAP and younger BAP performing similarly but older non-BAP performing better than older BAP. Results show that younger and older adults with elevated autistic traits show poorer ToM performance. Despite ToM difficulties being common in later life in the general population, this effect was not observed when using a ToM task designed to reflect real-world scenarios. However, results suggest that autistic traits and age could interact to increase risk for poor ToM performance in older adults who endorse elevated autistic traits. Autism Res 2020, 13: 751-762. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: The behaviors and characteristics commonly found in autism spectrum disorders have been linked to differences in understanding social situations. Similar difficulties have also been found in older age. We assessed social understanding in younger and older adults from the general population. Both younger and older adults who report more autism-like characteristics experience more difficulties with social understanding. However, few differences were found between younger and older adults.

Titre : Time perception in autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Gregory L. WALLACE, Auteur ; Francesca HAPPE, Auteur Année de publication : 2008 Article en page(s) : p.447-455 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Duration judgment has not been comprehensively examined in autism spectrum disorders (ASD), despite reports of perceptual idiosyncrasies in these individuals. Time estimation, production, and reproduction were tested in 25 individuals with ASD and 25 controls matched group-wise on age and IQ. Individuals with ASD performed comparably to matched controls in time estimation and production, but showed a tendency to outperform controls on a task of time reproduction. Time perception of large units is intact for children and adolescents with ASD. Time reproduction may represent a cognitive asset in ASD, likely reflecting strengths in eidetic-type imagery in which a pure recording of a stimulus is less affected by top-down modulation.

This study sought to address this by examining work readiness skills and their relation to vocational outcomes among 281 autistic young adults. It also examined perceived barriers and facilitators to employment as articulated by a subset of autistic adults. Results revealed a variegated work readiness profile. Stronger work readiness skills (particularly work style/adaptability) were associated with more favorable vocational outcomes. Autistic participants articulated both barriers and facilitators to employment related to the autism phenotype, job search/work readiness, and workplace education. These findings indicate the need for research on phenotype-driven vocational rehabilitation strategies as well as workplace psychoeducation/accommodations to support vocational outcomes for autistic adults.
