However, there is scarce evidence regarding metaphor production skills in ASD. Importantly, the exact source of metaphor processing difficulties in ASD remains largely controversial. The debate has mainly focused on the mediating role of structural language skills (i.e., lexical knowledge) and cognitive abilities (i.e., Theory of Mind and executive functions) in ASD individuals' ability to comprehend and generate metaphors. The present study examines metaphor comprehension and production in 18 Greek-speaking verbally able children with ASD and 31 typically-developing (TD) controls. Participants completed two tasks, namely, a low-verbal multiple-choice sentence-picture matching task that tested their ability to comprehend conventional predicate metaphors, and a sentence continuation task that assessed their ability to generate metaphors. The study also included measures of fluid intelligence, expressive vocabulary, and working memory within the sample. The results show that the ASD group had significantly lower performance than the TD group in both metaphor comprehension and production. The findings also reveal that expressive vocabulary skills were a key factor in the metaphor comprehension and production performance of the children with ASD. Working memory capacity was also found to correlate significantly with metaphor comprehension performance in the ASD group. Conversely, no correlations were found in the TD group with neither of the above factors. Of note, children with ASD generated significantly more inappropriate responses and no-responses to the metaphor production task compared with the control group. The overall results reveal that children with ASD had difficulty with both comprehending and using metaphorical language. The findings also indicate that TD children may employ diverse cognitive strategies or rely on different underlying skills when processing metaphors compared with children with ASD.</p>","PeriodicalId":72339,"journal":{"name":"Autism research : official journal of the International Society for Autism Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141914764","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, efforts to examine transdiagnostic factors (i.e., distress tolerance, behavioral activation) may afford more parsimonious means for assessment and treatment. To our knowledge, there has been little research on distress tolerance, behavioral activation, and depressive and anxiety symptoms in autistic adolescents to guide diagnostic practices and treatment planning. In the current study, we examined the interrelationships between these transdiagnostic factors and depressive and anxiety symptoms using ratings from 100 verbally fluent autistic adolescents without intellectual disability (M_age = 13.70, SD_age = 2.23, Range: 11:00-17:11 years) and 100 of their caregivers. Many adolescents reported male sex assigned at birth (61%), cisgender (87%), not Hispanic/Latinx (90%), and White (80%) identities. A series of correlational analyses were employed to examine associations between these constructs from youth and caregiver perspectives, and multiple linear regression analyses were conducted to explore the mediating roles of distress tolerance and behavioral activation. Preliminary results show that low distress tolerance and behavioral activation were associated with more severe internalizing symptoms per self- and caregiver-report. Some differences by rater emerged, which highlight the importance of multi-informant ratings in autism. Results from mediation analyses may show that behavioral activation may be more salient to assessments and treatment planning for depression than distress tolerance, while distress tolerance may be important for both anxiety and depression; however, findings are preliminary given the cross-sectional nature of the data. Findings suggest that these transdiagnostic concepts may be important to individualizing treatment approaches, including the timing of certain approaches, for anxiety and/or depression in autistic adolescents.</p>","PeriodicalId":72339,"journal":{"name":"Autism research : official journal of the International Society for Autism Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141894984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Study findings indicated that across a global sample (i.e., North America, Scandinavia, Europe, and Oceania) nearly half of all autistic individuals had an interaction with police and that those with a history of police contact were usually older, had higher educational qualifications, and were more likely to have a co-occurring mental health or developmental disorder. Among types of interactions, noncriminal encounters, such as welfare checks, traffic incidents, wandering, and behaviors associated with autism, were most common, followed by autistic individuals alleging a crime was committed against them.

Efforts to parse the heterogeneity of the autism spectrum through subgroups such as Asperger's and Profound Autism have been controversial, and have consistently struggled with issues of reliability, validity, and interpretability. Nonetheless, methods for successfully identifying clinically meaningful subgroups within autism are needed to ensure that research, interventions, and services address the range of needs experienced by autistic individuals. The purpose of this study was to generate and test whether a simple set of questions, organized in a flowchart, could be used in clinical practice and research to differentiate meaningful subgroups based on individuals' level of functioning. Once generated, subgroups could also be compared to the recently proposed administrative category of Profound Autism and to groupings based on standardized adaptive measures. Ninety-seven adults with autism or related neurodevelopmental disorders participating in a longstanding longitudinal study, or their caregivers if they could not answer for themselves, completed phone interviews when the participants were ~30 years old. Information from these phone interviews was used to generate vignettes summarizing characteristics and aspects of the daily lives of each participant (e.g., language level, vocational activities, and social relationships). Three expert clinicians then used these vignettes to classify each participant based on their level of support needs. Meaningfully distinct subgroups within the sample were identified which could be reliably distinguished from one another.

Therefore, the current study aims to investigate whether early differences in memory strategies lead to altered age-related effects in autism, particularly whether initial difficulties in strategy use become advantageous at older age (i.e., \"protective aging\"). A total of 147 participants across four groups (autistic younger/older, non-autistic younger/older) completed an online assessment. This assessment included a recognition version of the Visual Patterns Test (VPT) to evaluate semantic strategy use in visual memory, the Just Noticeable Difference (JND) size task for assessing visual processing, and the Multifactorial Memory Questionnaire to evaluate subjective memory functioning and strategy use (MMQ). Unexpectedly, all groups benefited from semantic features on the VPT, although the older groups performed less accurately and slower than the younger groups. The JND Size task showed no group differences. Autistic adults rated their MMQ memory as worse than non-autistic adults, despite reporting greater strategy use. These results indicate that cognitive strategies might be more similar between younger/older and autistic/non-autistic people than previously expected, although notable discrepancies between objective and subjective measures were present.

Further validation of these motor delays using a more robust normed, developmental measure is clearly warranted. In this analysis, a nationally representative sample from the SPARK study was used wherein parents completed the DCD-Q and a more widely used developmental/adaptive functioning measure, called the Vineland Adaptive Behavior Scales (VABS); which comprises of various developmental domains including the motor domain (N = 2,644 completed the DCD-Q and VABS). Eighty two percent children with ASD had a motor delay based on their DCD-Q scores whereas 77% children with ASD had a motor delay based on their VABS motor domain scores. Approximately 70% children with ASD had concurrent motor delay on the DCD-Q and the VABS (i.e., positive predictive value of DCD-Q). Furthermore, there was 81.2% accuracy in reporting a risk/no risk of motor delay across both measures. Overall, these statistics align with the recent reports on proportions of children with ASD having motor delays. Parents of ~70% children with ASD are reporting motor delays that are corroborated across two different motor measures. This not only validates the motor delays reported based on the DCD-Q but also indicates the need for concurrent motor screening using both DCD-Q and VABS for better detection of motor delays in children with ASD. Only 10%-32% of the current SPARK sample received any physical or recreational therapies.
