Racial and ethnic disparities in service utilization in autism are widely documented. Autism-related parental stigma may play a role if parents from racial/ethnic minoritized backgrounds experience dual stigma from autism and from membership in a marginalized group. This study examines racial/ethnic differences in autism-related stigma and compares the impact of stigma on service utilization in a large, diverse sample of US-based parents of autistic children (final sample = 764; White 41.

To date, there is no research on frank autism presentations of autistic adolescents and young adults, nor individuals diagnosed with autism spectrum disorder (ASD) in childhood who do not meet diagnostic criteria during or after adolescence (loss of autism diagnosis, LAD). In addition, there are currently no data on the factors that drive frank autism impressions in these adolescent groups.

Such unexpected bilingualism (UB) is therefore not driven by social interaction, rather, language acquisition appears to rely on less socially mediated learning and other cognitive processes. We hypothesize that UB children may rely on other cues, such as acoustic cues, of the linguistic input.

We modelled the speech from a selection of speakers (N = 26), with and without ASD, as a network of nodes defined by acoustic features. We used a community-detection algorithm to identify clusters of speakers who were acoustically similar and compared these clusters with atypicality ratings by naïve and expert human raters.

Research on autistic adults suggests significant heterogeneity in outcomes. A significant proportion of individuals struggle with intellectual disability and limited communication skills. Of the 67% who have age-appropriate cognitive skills, around half are expected to attain a college education, and 25% are likely to hold a full-time job.

Recent work has demonstrated the utility of the Beck Depression Inventory (BDI-II) in screening for depression in ASD. The current study extends this work by examining the convergence and divergence of self- and informant-reported depression in autistic (n = 258) and non-autistic (n = 255) young adults.

It is not yet clear how research defines, reports, and characterizes structural language abilities of autistic individuals eligible for school-based special education services (aged 3-21 years) in the United States.

Particularly in a clinical setting, these co-occurring externalizing disorders are very common in autism; rates of Attentional Deficit-Hyperactive Disorder (ADHD) and Oppositional Defiant Disorder (ODD) are as high as 83% (ADHD) and 73% (ODD; Joshi et al., 2010).

While some research suggests a limited capacity for imagination, other studies show heightened interest in fantasy and unique forms of creative thinking in ASD. This study explored daydreaming experiences in adults with ASD, with a focus on immersive daydreaming and its relation to divergent thinking abilities.

The recent International Society of Autism Research (INSAR) policy statement, Autism and the Criminal Justice System: Policy opportunities and challenges (INSAR, 2022), aims to prevent, reduce, and improve interactions between autistic individuals and the criminal justice system. This policy statement provides a foundation for considering how to include language in these important aims.
View Article and Find Full Text PDFFunctional near-infrared spectroscopy (fNIRS) is a promising tool for scientific discovery and clinical application. However, its utility depends upon replicable reporting. We evaluate reporting of sociodemographics in fNIRS studies of speech and language impairment and asked the following: (1) Do refereed fNIRS publications report participant sociodemographics? (2) For what reasons are participants excluded from analysis? This systematic review was preregistered with PROSPERO (CRD42022342959) and followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol.

Little research has examined the longitudinal course of post-loss cognitive processing, depression, and sleep difficulties. Further, little is known about the context of other stressors or the role of individual regulatory resources, such as attentional regulation, that might determine whether loss-related cognitive processing reduces distress.

This tutorial demonstrates how Bayesian statistics can be effectively and reliably implemented with a small, heterogeneous participant sample to promote reproducible and clinically relevant research.
Methods/results: We tested example research questions pertaining to language and clinical features in autism spectrum disorder (ASD; n = 20), a condition characterized by significant heterogeneity.
Although exclusion of racially and ethnically minoritized autistic individuals from research is a long-standing issue, we have yet to determine how exclusion impacts areas of autism research important for identifying language impairment. Diagnosis depends on the quality of the evidence (i.e.
View Article and Find Full Text PDFPurpose: Language and autism research each typically excludes racially and ethnically minoritized (REM) autistic individuals. In addition, in the case of autistic individuals with language impairment, investigators often approach caregivers to discuss research participation, rather than autistic individuals themselves. This gap limits the ecological validity of language research in autism.

However, there are ethical and practical concerns in implementing open science practices, especially when working with populations who are systematically excluded from and marginalized in communication sciences and disorders (CSD) research, such as Black, Indigenous, and People of Color (BIPOC) from clinical populations. The purpose of this article was to discuss these concerns and present actionable steps to support open science in CSD research with BIPOC.

Despite the tremendous clinical implications, we cannot predict whether a minimally verbal child is simply delayed (but will eventually develop spoken language) or will continue to struggle with verbal language, and might therefore benefit from learning an alternative form of communication. This is important for clinicians to know, to be able to choose the most helpful interventions, such as alternative forms of communication.

Purpose: Typical speakers tend to adopt words used by their conversational partners. This "lexical alignment" enhances communication by reducing ambiguity and promoting a shared understanding of the topic under discussion. Lexical alignment has been little studied to date in autism spectrum disorder (ASD); furthermore, it has been studied primarily via structured laboratory tasks that may overestimate performance.

Limitations of functional near-infrared spectroscopy (fNIRS) and other methods systematically exclude individuals with coarse or curly hair and darker skin. Despite these well-known limitations, clinical neuroscience manuscripts frequently fail to report participant race or ethnicity or reasons for excluding participants.
