Background: The aim was to explore the executive function profile of a group of Mexican people with Down syndrome (DS) aged 12-30 years during the COVID-19 pandemic. Aim: To analyse the relationships between mental, chronological age and eight domains of executive function. Method: Participants were 42 people with DS with a chronological age (CA)…

Objective: We leveraged common genetic variation underlying ADHD, educational attainment (EA) and cognition (COG) to understand the nature of the Behavior Rating Inventory for Executive Functions (BRIEF) and its relationship to academic functioning. Method: Participants were 991 youth, ages 7 to 17, consecutively referred for neuropsychiatric…

Cognitive flexibility (CF) is the ability to shift between concepts or rules. Difficulty with CF is associated with autism (i.e., ASD) as it contributes to repetitive behaviours. However, little is known about CF skills of autistic adolescents with low intelligence. This study uses the Wisconsin Card Sorting Task (WCST) to assess the CF of 36…

Performance on a single executive function (EF) task (e.g., a card sorting task) is often taken to represent ability on the underlying subcomponent of EF (e.g., set shifting) without accounting for the non-specific and non-executive skills employed to complete the task. This study used a manualised battery of EF tasks to derive individual task…

Dysexecutive syndrome has been consistently reported in children and adolescents with autism spectrum disorders (ASD). Particularly, impairments have been documented in working memory, inhibition, and mental flexibility. However, the relationship between executive impairments and intellectual functioning is far from clear in this population. This…

Understanding the relationship between executive functioning and its connection to working memory and adaptive functioning can inform planning and employment efforts. This study explored the relationship between memory and adaptive functioning with a sample of Autistic youths/young adults. Participant mean age was 21.3 (SD = 3.0). Of the 22…

Children develop their language capacities and executive functions (EF) throughout their school-aged years. Research has shown that bilingual children show different patterns of EF performance when compared to their monolingual counterparts. However, it is less clear how variations in children's multilingual experiences associate with variation in…

This study examined the spoken language, written language, and executive functions of 19 female adolescents with high risk factors in a long-term, holistic program. Standardized assessment results revealed that 63.2% of the participants had below-average spoken language, 68.5% had below-average written language, and 68.4% and 42.1% had some level…

The ability to deceive is a key milestone in social cognitive development for typically developing individuals. In this scoping review, we systematically searched the literature to summarise research on deceptive behaviour in autism and identify gaps in knowledge. Across the 28 studies identified, three main themes were synthesised, with seven…

Attention-deficit/hyperactivity disorder is one of the most common comorbidities in individuals with autism spectrum disorder. However, the clinical implications of the co-occurrence of these two disorders are still poorly understood. Based on a preregistered protocol (PROSPERO CRD42020193880), this systematic review identified 34 articles,…

Sex differences in autism may in part be understood by an atypical sex profile of executive function and non-executive function. In this study, we compared females and males with autism against non-autistic individuals on neuropsychological and self-report measures to examine whether any sex differences in executive function and non-executive…

Previous research has shown that cognitive development is sensitive to socio-economic status (SES) and multilinguistic experiences. However, these effects are difficult to disentangle and SES may modulate the effects of multilingualism. The present study used data from a large cohort of pupils who took part in the Study of Cognition, Adolescents…

"Executive function" (EF), critical for many developmental outcomes, emerge in childhood and continue developing into early adulthood (Blakemore & Choudhury, 2006). During adolescence there are important developments in "Hot EF," which involves using EF in emotionally salient contexts (Zelazo & Carlson, 2012). The…

Objectives: The aim of the study is to distinguish between perceptuomotor and cognitive inflexibility as the source of set-switching difficulties in children with autism spectrum disorder (ASD). Methods: Seventeen adolescents with ASD and 17 neurotypical controls were presented with a computerized sequencing game using colored shapes. The sequence…

Executive functioning (EF) is key to students' school and lifelong success and reflects both genetic predisposition and sensitivity to negative and positive experiences. Yet there is less available literature investigating the relationship between typical experiences within school environments and student EF development. This is unfortunate, as…
