Is language ability associated with behaviors of concern in autism? A systematic review / Katrina WILLIAMS ; Tamara MAY ; Wei Herng WAN ; Amanda BRIGNELL in Autism Research, 16-2 (February 2023)  

Public ISBD [article]  inAutism Research > 16-2 (February 2023) . - p.250-270 Titre : Is language ability associated with behaviors of concern in autism? A systematic review Type de document : Texte imprimé et/ou numérique Auteurs : Katrina WILLIAMS, Auteur ; Tamara MAY, Auteur ; Wei Herng WAN, Auteur ; Amanda BRIGNELL, Auteur Article en page(s) : p.250-270 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract This review systematically synthesized evidence on the association between structural language ability and behaviors of concern (BoC) in autism. Four databases were searched for studies that included >10 autistic participants, measures of structural language (content and/or form of language) and BoC, and an analysis of their association. BoCs included self-injurious behavior (SIB), aggression, tantrums, and externalizing behavior. Methodological quality of studies were assessed using the Newcastle Ottawa Scale. Forty-five publications (n = 11,961) were included. Forty studies were cross-sectional and five were prospective cohort studies. Over 70% of the studies investigating expressive language and SIB (n = 10), aggression (n = 5), tantrums (n = 3), and externalizing behavior (n = 17) reported an inverse association, where lower expressive language ability was associated with increased BoC. Eleven out of sixteen studies of combined expressive and receptive language reported an inverse relationship with SIB or aggression. All outcomes were rated as moderate to very low certainty of evidence. This review highlights evidence showing an inverse association between expressive or combined language ability and SIB, and externalizing behavior in autism. However, further high-quality studies that use standardized, consistent measures of language and behavior and investigate longitudinal associations are needed. Early detection and support for reduced structural language difficulties have substantial potential to assist in reducing BoC.

Increased resting-state thalamocortical functional connectivity in children and young adults with autism spectrum disorder / Quynh Trang Huong NGUYEN ; Dimitrios MYLONAS ; Susan L. SANTANGELO ; Dara S. MANOACH in Autism Research, 16-2 (February 2023)  

Public ISBD [article]  inAutism Research > 16-2 (February 2023) . - p.271-279 Titre : Increased resting-state thalamocortical functional connectivity in children and young adults with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Quynh Trang Huong NGUYEN, Auteur ; Dimitrios MYLONAS, Auteur ; Susan L. SANTANGELO, Auteur ; Dara S. MANOACH, Auteur Article en page(s) : p.271-279 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract There is converging evidence that abnormal thalamocortical interactions contribute to attention deficits and sensory sensitivities in autism spectrum disorder (ASD). However, previous functional MRI studies of thalamocortical connectivity in ASD have produced inconsistent findings in terms of both the direction (hyper vs. hypoconnectivity) and location of group differences. This may reflect, in part, the confounding effects of head motion during scans. In the present study, we investigated resting-state thalamocortical functional connectivity in 8-25â€year-olds with ASD and their typically developing (TD) peers. We used pre-scan training, on-line motion correction, and rigorous data quality assurance protocols to minimize motion confounds. ASD participants showed increased thalamic connectivity with temporal cortex relative to TD. Both groups showed similar age-related decreases in thalamic connectivity with occipital cortex, consistent with a process of circuit refinement. Findings of thalamocortical hyperconnectivity in ASD are consistent with other evidence that decreased thalamic inhibition leads to increase and less filtered sensory information reaching the cortex where it disrupts attention and contributes to sensory sensitivity. This literature motivates studies of mechanisms, functional consequences, and treatment of thalamocortical circuit dysfunction in ASD.

Beyond its role in hallmark features of ASD, the cerebellum and its connectivity with forebrain structures also play a role in navigation. However, the current understanding of navigation abilities in ASD is equivocal, as is the impact of the disorder on the functional anatomy of the cerebellum. In the present study, we investigated the navigation behavior of a population of ASD and typically developing (TD) adults related to their brain anatomy as assessed by structural and functional MRI at rest. We used the Starmaze task, which permits assessing and distinguishing two complex navigation behaviors, one based on allocentric learning and the other on egocentric learning of a route with multiple decision points. Compared to TD controls, individuals with ASD showed similar exploration, learning, and strategy performance and preference. In addition, there was no difference in the structural or functional anatomy of the cerebellar circuits involved in navigation between the two groups. The findings of our work suggest that navigation abilities, spatio-temporal memory, and their underlying circuits are preserved in individuals with ASD.

Late diagnosis of autism spectrum disorder-Journey, parents' concerns, and sex influences / Sivan GAZIT ; Tal PATALON ; Yael LEITNER ; Ran S. ROTEM in Autism Research, 16-2 (February 2023)  

Public ISBD [article]  inAutism Research > 16-2 (February 2023) . - p.294-301 Titre : Late diagnosis of autism spectrum disorder-Journey, parents' concerns, and sex influences Type de document : Texte imprimé et/ou numérique Auteurs : Sivan GAZIT, Auteur ; Tal PATALON, Auteur ; Yael LEITNER, Auteur ; Ran S. ROTEM, Auteur Article en page(s) : p.294-301 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Despite increasing awareness for diagnosing autism spectrum disorder (ASD) and initiating treatments early in life, many children and adolescents continue to be diagnosed at a relatively older age. Focusing on children who first received an ASD diagnosis at age six or older, this study aimed to describe the symptoms that parents reported when ASD was diagnosed, follow the patients' clinical trajectory prior to receiving the diagnosis, and describe differences in symptoms and prior diagnoses between males and females cases. We included 258 children (205 males and 53 females) who were first diagnosed with autism at age 6-18 in 2017-2018. We retrieved demographic information, neurologic and developmental symptoms, diagnoses, and medications dispensing history from the children's electronic medical charts. The data indicated that prior diagnoses of language delays and attention deficit hyperactivity disorder were common among children with a late ASD diagnosis. Two thirds of the children were prescribed one or more medications to treat psychosocial and behavioral conditions before receiving a late ASD diagnosis. Difficulties in social relationships with peers were the leading reported symptoms by parents at the time of ASD diagnosis. Across these different domains, some differences were found between males and females, including a somewhat higher cognitive level in males, who were also more likely to present aggressive behavior.

LEUNG, Auteur Article en page(s) : p.302-314 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract The current study aimed at testing and developing alternative short versions of autism spectrum quotient (AQ-10) (adult [self-report], adult [parent-report], adolescent, and child versions) for use in Hong Kong. First, the various versions of AQ-10 developed in the United Kingdom (the AQ-10-UK) were applied to Hong Kong Chinese samples and demonstrated satisfactory discriminative power (AUCs 0.77-0.94). Second, the Hong Kong Chinese versions of AQ-10 (AQ-10-HK) were developed, using the same methodology as in the original UK study. There were some changes in the choice of items and cut-offs. The AQ-10-HK demonstrated slightly greater discriminative power (AUCs 0.88-0.97) to that of the AQ-10-UK, but the differences in AUCs were not statistically significant. Compared to the corresponding full-length versions, both the UK and HK short forms did not seem to lose any significant discriminative power. Yet, the various versions of AQ, be they the full-length or AQ-10, appeared to consistently exhibit slightly smaller AUCs with the Hong Kong Chinese samples than with the UK samples. So, this study found both cross-cultural similarities and differences. The AQ-10-HK was recommended for local practice to maximize the advantage gained. Yet, for international multi-site research collaboration, involving the UK and HK, the original AQ-10-UK can be used for direct comparison of data.

Effects of social complexity and gender on social and non-social attention in male and female autistic children: A comparison of four eye-tracking paradigms / Noah J. SASSON ; Julia PARISH-MORRIS ; Clare HARROP in Autism Research, 16-2 (February 2023)

SASSON, Auteur ; Julia PARISH-MORRIS, Auteur ; Clare HARROP, Auteur Article en page(s) : p.315-326 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Eye tracking has long been used to characterize differences in social attention between autistic and non-autistic children, but recent work has shown that these patterns may vary widely according to the biological sex of the participants and the social complexity and gender-typicality of the eye tracking stimuli (e.g., barbies vs. transformers). To better understand effects of sex, social complexity, and object gender-typicality on social and non-social gaze behavior in autism, we compared the visual attention patterns of 67 autistic (ASD) and non-autistic (NA) males (M) and females (F) (ASD M = 21; ASD F = 18; NA M = 14; NA F = 14) across four eye tracking paradigms varying in social complexity and object gender-typicality. We found consistency across paradigms in terms of overall attention and attention to social stimuli, but attention to objects varied when paradigms considered gender in their stimulus design. Children attended more to gendered objects, particularly when the gender-typicality of the object matched their assigned sex. These results demonstrate that visual social attention in autism is affected by interactions between a child's biological sex, social scene complexity, and object gender-typicality and have broad implications for the design and interpretation of eye tracking studies.

Atypical development of social and nonsocial working memory capacity among preschoolers with autism spectrum disorders / Dong GUO ; Zaifeng GAO ; Kunlin WEI in Autism Research, 16-2 (February 2023)

However, no study has investigated social WM and its early development. Using biological motion stimuli, our study assessed the development of social and nonsocial WM capacity among children with or without ASD across the age span between 4 and 6 (N = 150). While typically developing (TD) children show a rapid development from age 5 to 6, children with ASD showed a delayed development for both social and nonsocial WM capacity, reaching a significant group difference at age 6. Furthermore, we found a negative correlation between social (but not nonsocial) WM capacity and the severity of autistic symptoms among children with ASD. In contrast, there is a positive correlation between both types of WM capacity and intelligence among TD children but not among children with ASD. Our findings thus indicate that individuals with ASD miss the rapid development of WM capacity in early childhood and, particularly, their delayed social WM development might contribute to core symptoms that critically depend on social information processing.

Distinct social attention profiles in preschoolers with autism contrasted to fragile X syndrome / Frederick SHIC ; Sreeja VARANASI ; Jane E. ROBERTS in Autism Research, 16-2 (February 2023)  

Public ISBD [article]  inAutism Research > 16-2 (February 2023) . - p.340-354 Titre : Distinct social attention profiles in preschoolers with autism contrasted to fragile X syndrome Type de document : Texte imprimé et/ou numérique Auteurs : Frederick SHIC, Auteur ; Sreeja VARANASI, Auteur ; Jane E. ROBERTS, Auteur Article en page(s) : p.340-354 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Social attention is a critical skill for learning and development. Social attention difficulties are present in both non-syndromic autism spectrum disorder (nsASD) and fragile X syndrome (FXS), and our understanding of these difficulties is complicated by heterogeneity in both disorders, including co-occurring diagnoses like intellectual disability and social anxiety. Existing research largely utilizes a single index of social attention and rarely includes children with intellectual impairment or uses a cross-syndrome approach. This study investigated whether multi-trait social attention profiles including naturalistic initial eye contact, facial attention, and social scene attention differ in preschool children with nsASD and FXS matched on developmental ability (DQ) and contrasted to neurotypical (NT) controls. The relationship between DQ, ASD severity, and social anxiety and social attention profiles was also examined. Initial eye contact related to social scene attention, implicating that naturalistic social attention is consistent with responses during experimental conditions. Reduced eye contact and lower social scene attention characterized nsASD and FXS. Children with nsASD displayed less facial attention than FXS and NT children, who did not differ. Lower DQ and elevated ASD severity associated with decreased eye contact in nsASD and FXS, and lower DQ was associated with lower social scene attention in FXS. Sex, social anxiety, and age were not associated with social attention. These findings suggest social attention profiles of children with nsASD are highly similar to, yet distinct from, children with FXS. Children with nsASD may present with a global social attention deficit whereas FXS profiles may reflect context-dependent social avoidance.

Initial eye contact related to social scene attention, implicating that naturalistic social attention is consistent with responses during experimental conditions. Reduced eye contact and lower social scene attention characterized nsASD and FXS. Children with nsASD displayed less facial attention than FXS and NT children, who did not differ. Lower DQ and elevated ASD severity associated with decreased eye contact in nsASD and FXS, and lower DQ was associated with lower social scene attention in FXS. Sex, social anxiety, and age were not associated with social attention. These findings suggest social attention profiles of children with nsASD are highly similar to, yet distinct from, children with FXS. Children with nsASD may present with a global social attention deficit whereas FXS profiles may reflect context-dependent social avoidance.

Audiovisual temporal binding window narrows with age in autistic individuals / Armando BERTONE in Autism Research, 16-2 (February 2023)  

Public ISBD [article]  inAutism Research > 16-2 (February 2023) . - p.355-363 Titre : Audiovisual temporal binding window narrows with age in autistic individuals Type de document : Texte imprimé et/ou numérique Auteurs : Armando BERTONE, Auteur Article en page(s) : p.355-363 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Atypical sensory perception has been recognized in autistic individuals since its earliest descriptions and is now considered a key characteristic of autism. Although the integration of sensory information (multisensory integration; MSI) has been demonstrated to be altered in autism, less is known about how this perceptual process differs with age. This study aimed to assess the integration of audiovisual information across autistic children and adolescents. MSI was measured using a non-social, simultaneity judgment task. Variation in temporal sensitivity was evaluated via Gaussian curve fitting procedures, allowing us to compare the width of temporal binding windows (TBWs), where wider TBWs indicate less sensitivity to temporal alignment. We compared TBWs in age and IQ matched groups of autistic (n = 32) and neurotypical (NT; n = 73) children and adolescents. The sensory profile of all participants was also measured. Across all ages assessed (i.e., 6 through 18â€years), TBWs were negatively correlated with age in the autistic group. A significant correlation was not found in the NT group. When compared as a function of child (6-12â€years) and adolescent (13-18â€years) age groups, a significant interaction of group (autism vs NT) by age group was found, whereby TBWs became narrower with age in the autistic, but not neurotypical group. We also found a significant main effect of age and no significant main effect of group. Results suggest that TBW differences between autistic and neurotypical groups diminishes with increasing age, indicating an atypical developmental profile of MSI in autism which ameliorates across development.

These sensory specificities may result from an excitation/inhibition imbalance with a poorly understood of their level of convergence with genetic alterations in GABA-ergic and glutamatergic pathways. In our study, we aimed to characterize the hypo/hyper-sensory profile among autistic individuals. We then explored its link with the burden of deleterious mutations in a subset of individuals with available whole-genome sequencing data. To characterize the hypo/hyper-sensory profile, the differential Short Sensory Profile (dSSP) was defined as a normalized and centralized hypo/hypersensitivity ratio from the Short Sensory Profile (SSP). Including 1136 participants (533 autistic individuals, 210 first-degree relatives, and 267 controls) from two independent study samples (PARIS and LEAP), we observed a statistically significant dSSP mean difference between autistic individuals and controls, driven mostly by a high dSSP variability, with an intermediated profile represented by relatives. Our genetic analysis tended to associate the dSSP and the hyposensitivity with mutations of the GABAergic pathway. The major limitation was the dSSP difficulty to discriminate subjects with a similar quantum of hypo- and hyper-sensory symptoms to those with no such symptoms, resulting both in a similar ratio score of 0. However, the dSSP could be a relevant clinical score, and combined with additional sensory descriptions, genetics and endophenotypic substrates, will improve the exploration of the underlying neurobiological mechanisms of sensory processing differences in autism spectrum.

The network structure of the Special Interests Survey / Marshall T. BEAUCHAMP ; Kerri P. NOWELL ; Courtney J. BERNARDIN ; Stephen M. KANNE in Autism Research, 16-2 (February 2023)

Indeed, a significant challenge in identifying and classifying SIs lies in capturing the vast and diverse scope of potential interests in this population. The recently developed Special Interest Survey (SIS) is a caregiver-report measure to improve SI characterization by capturing a broad range of past and current SIs. In the present study, we performed a network analysis of the SIS to examine relations between SIs and identify distinct interest clusters. We analyzed data from 1992 caregivers of autistic youths who completed the SIS. The network of SIs was densely interconnected, characterized by six communities of interests: Fact-seeking, Engineering, Order-seeking, Object Attachment, Entertainment, and Scholarly Pursuits. Findings suggest that the structure of the observed network is likely to generalize to similar samples. Of all the SIs and their respective communities, behaviors related to Fact-seeking were identified as the most central, meaning that endorsement of these interests was most strongly related to co-endorsement of other SIs. These findings lay the groundwork for future work on SIs, such as improved assessment techniques and linkage of SIs to a broad range of demographic variables, youth characteristics, and autism symptoms.

Recent evidence suggests that a distinction can be drawn between interests that, although characterized by unusually high intensity and/or inflexibility, are otherwise common in terms of their content (e.g., an interest in movies or animals), labeled as restricted interests (RI), and interests that are generally not salient outside of autism (e.g., an interest in traffic lights or categorization), labeled as unusual interests (UI). The current study aimed to further characterize RI and UI by exploring their association with age, sex, IQ, and social motivation, as well as to examine differences in the adaptive benefits and negative impacts of these two subdomains. Parents of 1892 autistic children and adolescents (Mage = 10.82, SDage = 4.14; 420 females) completed an online survey including the Dimensional Assessment of Restricted and Repetitive Behaviors and the Social Communication Questionnaire. Both RI and UI were found to be highly frequent. Sex-based differences were observed in the content, but not intensity, of CI such that females were more likely to show interests with a social component. Finally, RI and UI showed distinct patterns of association with age, sex, IQ, and social motivation, as well as metrics of adaptive benefits and negative impacts. Findings afford a more nuanced understanding of sex-based differences in CI and, crucially, provide preliminary evidence that RI and UI represent distinct constructs that should be studied independently in future research.

Autism-related language preferences of English-speaking individuals across the globe: A mixed methods investigation / Lydia HICKMAN ; Joan LEUNG ; Ruth MONK ; Alicia MONTGOMERY ; Hannah HEATH ; Sophie SOWDEN in Autism Research, 16-2 (February 2023)

Whilst these discussions have largely revolved around the suitability of identity-first language and person-first language, more recently this debate has broadened to encompass other autism-related terminology (e.g., 'high-functioning'). To date, academic studies have not investigated the language preferences of autistic individuals outside of the United Kingdom or Australia, nor have they compared levels of endorsement across countries. Hence, the current study adopted a mixed-methods approach, employing both quantitative and qualitative techniques, to explore the linguistic preferences of 654 English-speaking autistic adults across the globe. Despite variation in levels of endorsement between countries, we found that the most popular terms were similar-the terms 'Autism', 'Autistic person', 'Is autistic', 'Neurological/Brain Difference', 'Differences', 'Challenges', 'Difficulties', 'Neurotypical people', and 'Neurotypicals' were consistently favored across countries. Despite relative consensus across groups, both our quantitative and qualitative data demonstrate that there is no universally accepted way to talk about autism. Our thematic analysis revealed the reasons underlying participants' preferences, generating six core themes, and illuminated an important guiding principle-to respect personal preferences. These findings have significant implications for informing practice, research and language policy worldwide.

Despite memory, IPS and EF being sensitive to age-related change, little is known about the cognitive profile of older adults with high autistic traits. This study explores cross-sectional memory, IPS and EF task performance in a large sample of older adults in the online PROTECT cohort (n = 22,285, aged 50-80â€years), grouped by high vs. low autistic traits. Approximately 1% of PROTECT participants (n = 325) endorsed high autistic traits [henceforth Autism Spectrum Trait (AST) group]. Differences between AST and age-, gender-, and education-matched comparison older adults (COA; n = 11,744) were explored on memory, IPS and EF tasks and questionnaires administered online. AST had lower performance than COA on tasks measuring memory, working memory, sustained attention, and information processing. No group differences were observed in simple attention or verbal reasoning. A similar pattern of results was observed when controlling for age, and current depression and anxiety symptoms. In addition, AST self-reported more cognitive decline than COA, but this difference was not significant when controlling for current depression symptoms, or when using informant-report. These findings suggest that autistic traits are associated with cognitive function in middle-aged and later life. Older adults with high autistic traits experienced more performance difficulties in a range of memory, IPS and EF tasks compared with the low autistic traits comparison group. Further longitudinal work is needed to examine age-related change in both older autistic and autistic trait populations.

A systematic review and meta-analysis of associations between primarily non-autistic people's characteristics and attitudes toward autistic people / Da-Yea SONG ; Kristen BOTTEMA-BEUTEL ; Kristen GILLESPIE-LYNCH ; Eilidh CAGE in Autism Research, 16-2 (February 2023)

Of 47 studies included in the narrative synthesis, White undergraduate students were surveyed most frequently. Demographic characteristics were the factors most frequently tested for associations with attitudes, followed by contact-related factors (i.e., quantity and quality), knowledge about autism, trait and personality factors, and other factors that did not fit into a single category. Internal consistency was not reported for some instruments assessing raters' characteristics; some instruments had alpha levels lower than 0.70, and many characteristics of raters were measured using one-item measures. Moreover, theoretical motivations for investigating the raters' characteristics were rarely provided. A total of 36 studies were included in the meta-analysis, which showed that attitudes toward autistic people were significantly associated with participants' gender, knowledge about autism, and quality and quantity of their previous contact with autistic people, but not with their age or autistic traits. These findings indicate a need for more studies that focus on context-related characteristics (e.g., institutional variables such as support/commitment to inclusion), use reliable instruments to measure non-autistic people's characteristics, and situate their investigation in a theoretical framework.

These findings indicate a need for more studies that focus on context-related characteristics (e.g., institutional variables such as support/commitment to inclusion), use reliable instruments to measure non-autistic people's characteristics, and situate their investigation in a theoretical framework.

How do autistic people fare in adult life and can we predict it from childhood? / Rachel KENT ; Tony CHARMAN ; Gillian BAIRD ; Andrew PICKLES ; Emily SIMONOFF in Autism Research, 16-2 (February 2023)  

Public ISBD [article]  inAutism Research > 16-2 (February 2023) . - p.458-473 Titre : How do autistic people fare in adult life and can we predict it from childhood? Type de document : Texte imprimé et/ou numérique Auteurs : Rachel KENT, Auteur ; Tony CHARMAN, Auteur ; Gillian BAIRD, Auteur ; Andrew PICKLES, Auteur ; Emily SIMONOFF, Auteur Article en page(s) : p.458-473 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract This study describes social, mental health, and quality of life outcomes in early adulthood, and examines childhood predictors in the Special Needs and Autism Project (SNAP), a longitudinal population-based cohort. Young autistic adults face variable but often substantial challenges across many areas of life. Prediction of outcomes is important to set expectations and could lead to the development of targeted early intervention. Autistic children were enrolled at age 12 and parents reported outcomes 11â€years later when their children were age 23 (n = 121). Thirty six percent of autistic adults were in competitive employment or education and 54% had frequent contact with friends. Only 5% of autistic adults were living independently, and 37% required overnight care. Moderate or severe anxiety and depression symptoms were found for 11% and 12% of young adults, respectively. Subjective quality of life was similar to UK averages except for social relationships. Using childhood IQ, autism traits and adaptive functioning meaningful predictions can be made of living situation, employment and education and physical health. Prediction was poor for friendships, mental health outcomes and other aspects of quality of life. Our results suggest that although young autistic adults face challenges across normative, social outcomes, they may be faring better in regard to mental health or quality of life. Childhood IQ, autism traits and adaptive functioning are most useful for predicting outcomes. After accounting for these factors, childhood measurements of behavioral and emotional problems and language offered little improvement in prediction of adult outcomes.
