The use of self-report to assess anxiety in adolescents with intellectual disability (ID) is notably underexplored. This study examined the impact of youth-level factors (i.e., age, verbal and cognitive ability, adaptive skills) on anxiety self-report completion and parent-youth agreement among 72 autistic adolescents with ID. We also examined if…

Australian children aged 6-9 years (N = 120, 71 females; data collected in 2021-2022) were tasked with remembering the locations of 1, 3, 5, and 7 targets hidden under 25 cups on different trials. In the critical test phase, children were provided with a limited number of tokens to allocate across trials, which they could use to mark target…

There are contentious and persistent gender differences reported in some measures of spatial skills, particularly mental rotation and, to a lesser extent, perspective-taking, which may have an impact on mathematics success. Furthermore, pathways between spatial skills and mathematics may be mediated by other cognitive factors, such as fluid…

The goal of the present study was to test theories about the extent to which individual differences in word reading align with those in spelling and the extent to which other cognitive and linguistic skills play different roles in word reading and spelling. Using data from 1,116 children ranging from 8 to 17 years, we modeled word reading and…

Understanding of preterm infant cognitive competences across the first year of life is limited regarding the developmental constructs of continuity, stability, coherence, and predictive validity as well as how they manifest by age and country of origin. This prospective longitudinal study examined and compared mean-level continuity,…

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)…

Theorized mechanisms linking views on aging, self-regulation, and well-being have not previously been examined longitudinally. This study considers goal re-engagement as a potential mediator of longitudinal relationships between awareness of age-related change (AARC) and vitality. We expected that more positive perceptions of aging (i.e., higher…

Previous research links resting frontal gamma power to key developmental outcomes in young neurotypical (NT) children and infants at risk for language impairment. However, it remains unclear whether gamma power is specifically associated with language or with more general cognitive abilities among young children diagnosed with autism spectrum…

Keeping a conversation going is the social glue of friendships. The DSM criteria for autism list difficulties with back-and-forth conversation but does not necessitate that all autistic children will be equally impacted. We carried out three studies (two pre-registered) with verbally fluent school children (age 5-9 years) to investigate how…

This study aims to investigate the linguistic organisation and coherence of personal narratives among children with Developmental Language Disorder (DLD) to provide insight into their communication skills in everyday contexts. A cohort of 10-year-old Croatian-speaking children diagnosed with DLD (n = 50, M = 10;8) and their gender-matched…

Social interaction depends on turn-taking and adapting to one's conversational partner, yet little is known about the typical and atypical development of these abilities. We investigated this in a longitudinal corpus of spontaneous speech in 64 parent-child dyads: 32 typically developing children (20.27 months at start, six girls, 24 White) and 32…

The perception and manipulation of spatial information are essential for mathematical learning, and research highlights gender differences in spatial abilities. The present study contributes to the question of whether these differences are evident at earlier ages and how they interact with task complexity in mental rotation. We developed the…

There is growing theoretical and empirical consensus for a role of awareness of suprasegmental phonology, also known as prosody, or the rhythmic elements of speech, in reading comprehension. Here we explore a potential mechanism by which this relation functions: awareness of how punctuation reflects prosody, for instance appreciating that a period…

Background and Objectives: Normative reference of the connected speech measures (both micro-structural and macro-structural) for descriptive discourse is fundamental to systematic discourse analysis because it provides an anchor for comparison. This study aims to establish a comprehensive normative reference for connected speech measures in…

Feasible and accurate assessment tools developed for non-specialists are needed to scale community-based models of autism evaluation. The purpose of this study was to evaluate use of the Screening Tool for Autism in Toddlers and Young Children (STAT) when used by primary care practitioners (n = 10) across a statewide system of early diagnosis set…
