Joint attention (JA) has been found to correlate with many developmental outcomes. However, little is known about how naturalistic JA is established and develops during early infancy. In this study, free-flowing tabletop toy play between infants at 5 and 15 months and their mothers (N = 48 dyads; 65% white) was observed to (1) examine changes in…

In today's digital world, understanding refresh-rate implications on visual perception and energy consumption is crucial. While high refresh rates enhance motion perception and user experience, they also increase energy usage, prompting the need for adaptive solutions like variable refresh rates. This study examines whether users notice or are…

Attention is biased toward features aligning with task goals and stimuli previously allocated attentional priority (selection history). The relationship between selection history and the strategic control of attention has scarcely been explored. In the present study, we utilized a modified version of the Adaptive Choice Visual Search (ACVS) task…

Objective: Investigate whether patterns of heart rate variability (indexed via respiratory sinus arrhythmia) and visual attention at 12 to 18 months of age predict elevated ADHD symptoms, autism, or neither during the preschool period. Method: Ninety infants 12 to 18 months of age (M = 17.27, SD = 1.93; 36 females; 82.2% non-Hispanic) participated…

Objective: Neurotypical individuals can prioritize particularly valuable information in working memory. This is a well-replicated effect, demonstrated across a wide variety of task factors and age groups. However, it is not clear if individuals with symptoms of ADHD are able to do this effectively, as there is some evidence this group struggle to…

The relationship between focus of attention instructions and motor performance is a topic of significant research interest. It is widely accepted that attending to the mechanics of the movement when performing a motor task (internal focus) yields poorer performance and less effective movement organization than attending to the movement outcome…

Although numerous studies have shown that external focus (EF) enhances sports performance more than internal focus (IF) does, some findings suggest that preference (liking and usefulness) and familiarity with instructions can act as moderators. However, little is known regarding the concept of preference or familiarity in the context of motor…

Motor performance has been shown to be superior when focusing on a physically farther environmental cue (external focus-far, EF-far) instead of a cue proximal to the body (EF-near). However, little is known about whether these foci affect bimanual tasks. Further, the effect of visual information on attentional focus is unclear. In the present…

Objective: To compare the effect of motivational features on sustained attention in children born very preterm and at term. Method: EEG was recorded while 34 8-to-11-year-old children born very preterm and 34 term-born peers completed two variants of a cued continuous performance task (CPT-AX); a standard CPT-AX with basic shape stimuli, and…

Objective: Neurocognitive impairments are associated with child and adult ADHD in clinical settings. However, it is unknown whether adult ADHD symptoms in the general population are associated with the same pattern of cognitive impairment. We examined this using a prospective, population-based cohort spanning birth to age 25 years. Methods: We…

Objectives: Children with ADHD commonly exhibit sleep disturbances, but there is limited knowledge about how sleep and sleep timing are associated with cognitive dysfunction in children with ADHD. Methods: Participants were 350 children aged 5 to 12 years diagnosed with ADHD. Three sleep-related constructs--time in bed, social jetlag (i.e.,…

Purpose: Fragile X syndrome (FXS) is a single-gene disorder characterized by moderate to severe cognitive impairment and a high association with autism spectrum disorder (ASD) and Attention-Deficit/Hyperactivity Disorder (ADHD). Atypical visual attention is a feature of FXS, ASD, and ADHD. Thus, studying early attentional patterns in young…

Impairments in joint attention are considered core symptoms of autism spectrum disorder (ASD) and are crucial for early assessment and intervention. However, existing information about visual attention during joint attention and its relation to developmental functioning is limited. The current study investigated the visual attention differences…

Joint attention is essential for establishing effective social communication. However, children with Autism Spectrum Disorder (ASD) often exhibit deficits in joint attention, which hinder their social interactions with peers and adults. Traditional assessment methods predominantly rely on expert observation, lacking objective measures of…

Purpose: Research suggests that attention-deficit/hyperactivity disorder (ADHD) and its symptoms occur more frequently in individuals who stutter. The purpose of this study was to document the prevalence of ADHD diagnoses and ADHD symptoms in children who stutter and examine potential relationships between ADHD and stuttering characteristics.…
