We examined potential phenotypic differences in eye gaze avoidance exhibited by boys with autism spectrum disorder (ASD) and boys with fragile X syndrome (FXS). In Study 1, the Eye Contact Avoidance Scale (ECAS) was administered to caregivers of boys aged 7-18 years with FXS (n = 148), ASD (n = 168), and mixed developmental disabilities (MDD; n = 128). In Study 2, subsets of boys with FXS (n = 31) and boys with ASD (n = 25) received a brief behavioral treatment probe to improve eye contact. Results showed that boys with FXS obtained significantly higher scores on the ECAS compared to boys with ASD and MDD. Exposure to the brief behavioral treatment probe resulted in significant decreases in scores for boys with FXS, but not for boys with ASD.

This study aimed to examine the level of discrimination against people with intellectual disability during COVID-19, and assessed stereotypes, levels of familiarity with people with intellectual disability, and personal experiences with COVID-19 as potential correlates. A cross-sectional study was conducted using a large sample from the Dutch population (n = 1,797). Salient stereotype factors of people with intellectual disability were "friendly" and "in need of help," but not "give nuisance." Those respondents who were unfamiliar with people with intellectual disability in real life demonstrated higher levels of discrimination, perceiving them as more of a nuisance and as being less in need of help, in comparison to those who were more familiar. People with intellectual disability were judged by an ambivalent set of stereotypes during the COVID-19 pandemic that were in line with pre-COVID-19 findings and as such seemed to be fairly persistent and robust. There is a pressing need to both raise awareness of stereotypes towards and discrimination against people with intellectual disability via advocacy and education, and to facilitate positive encounters.

This study compared mental state language (talk about emotions, thoughts, intentions, etc.) used by 6- to 11-year-old children with Down syndrome (DS) to a younger typically developing (TD) comparison group matched by nonverbal cognition. We aimed to determine (1) whether mental state language use is delayed in DS relative to developmental expectations, and (2) if there are differences between groups in the association between mental state language and developmental factors (emotion knowledge, expressive language). Rate of mental state language use was significantly lower in the group with DS, but the number of different mental state terms was not significantly different. Nuanced patterns of similarity and difference emerged between groups regarding the association between mental state language and other developmental factors.

The Nisonger Child Behavior Rating Form (NCBRF) was developed to specifically screen psychopathology and problem behavior in children and adolescents with IDD. This study aimed to update the NCBRF to the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) and screen for the most prevalent psychopathologies that affect children and adolescents with IDD. The authors re-aligned the existing items to fit within a DSM-5 framework, and then used the Delphi method with a panel of experts in IDD to evaluate the NCBRF items. The revision process included deleting and revising existing items and formulating new items. We obtained a final item pool after three iterations. The Delphi process and resulting item pool are described in this article.

The NIH Toolbox Cognition Battery (NIHTB-CB) was developed for epidemiological and longitudinal studies across a wide age span. Such a tool may be useful for intervention trials in conditions characterized by intellectual disability (ID), such as Williams syndrome (WS). Three NIHTB-CB tasks, including two executive functioning (Flanker, Dimensional Change Card Sort) and one episodic memory (Picture Sequence Memory) task, were given to 47 individuals with WS, ages 4 to 50, to evaluate feasibility (i.e., proportion of valid administrations) in this population. Findings indicated that NIHTB-CB tests showed good feasibility. Flanker and DCCS age-corrected scores were negatively correlated with age and showed floor effects, indicating these scores may not be useful for quantifying performance on these NIHTB-CB tests in ID.

This pilot study sought to identify potential markers of improvement from pre-post treatment in response to computerized working memory (WM) training for youth (ages 8-18) with autism spectrum disorder (ASD) and comorbid intellectual disability (ID) in a single arm, pre-post design. Participants included 26 children with ASD and 18 with comorbid ASD and fragile X syndrome (ASD+FXS). Analyses were adjusted for age and IQ. The ASD group demonstrated greater improvement on WM training relative to the ASD+FXS group. Participants improved on WM and far transfer outcomes, however, there were no significant group differences in improvement except for repetitive behavior. Higher hyperactivity/impulsivity ratings predicted lower performance on visuospatial WM. Findings suggest cognitive training may be beneficial for youth with ASD and ID, warranting further exploration.

The block design task (BDT) is a visuospatial measure that individuals with Williams syndrome (WS) perform poorly on. However, it is unclear what underlies their impaired performance. This study investigated whether poorer performance is a result of visuospatial difficulties, executive function (EF) difficulties, atypical looking strategies, or a combination of these. Eleven individuals with WS participated alongside mental age (MA)- and chronological age (CA)-matched control groups. Eye movements were recorded while they took the BDT. Dwell times and visits to areas of interest in WS differed from CA, but not MA, groups. Findings suggest that BDT abilities of individuals with WS are delayed, but not atypical. Delays result from visuospatial and attention-switching difficulties rather than atypical looking strategies.

People with disabilities have not been adequately represented in strengths-based research. This study is the first to examine strengths and positive influences of young children with fetal alcohol spectrum disorder (FASD). Thirty adoptive and relative caregivers of children with FASD reported their children's strengths and positive influences and completed measures on family functioning. Using a conversion mixed design, we described themes in strengths and influences, degree of caregiver positivity and relationships with child and family functioning. Caregivers reported wide-ranging strengths and positive influences. Frequency of adaptive strengths correlated with measures of family functioning, but thematic strengths and positive influences did not. Strengths and positive influences are distinct from measures of functioning and are not well captured in deficit-focused research.
