Purpose: This study focuses on examining how individual differences, including biological, linguistic, and cognitive traits, and prosodic focus affect the computation biases and reaction time (RT) associated with quantity scalar terms in Mandarin-speaking children aged 3-8 years. Method: The participants of this study were 27 Mandarin-speaking…

The face inversion effect is an important indicator of holistic face perception and reflects the developmental level of face processing. This study examined the face inversion effect in deaf or hard of hearing (DHH) children aged 7-17 using the face dimensions task. This task uses photographic images of a face, in which configural and featural…

Observational learning is essential for the acquisition of new behavior in educational practices and daily life and serves as an important mechanism for human cognitive and social-emotional development. However, we know little about its underlying neurocomputational mechanisms from a developmental perspective. In this study we used model-based…

Purpose: Repetitive negative thinking (RNT) is the process of engaging in negatively valenced and habitual thought patterns. RNT is strongly associated with mental health conditions and often affects quality of life. This study explored RNT in older school-age children and adolescents who stutter to quantify the relationship between RNT and…

Statistical learning (SL), the ability to detect and extract regularities from inputs, has been considered as an early-maturing and domain-general mechanism that is critical for typical language development. However, recent evidence in neurotypical adults and children have found that individuals can vary in their SL abilities across linguistic and…

Background: Despite the ability of cochlear implants (CIs) to provide children with access to speech, there is considerable variability in spoken language outcomes. Research aimed at identifying factors influencing speech production accuracy is needed. Aims: To characterize the consonant production accuracy of children with cochlear implants…

We explored the causal role of individual and age-related differences in working memory (WM) capacity in long-term memory (LTM) retrieval. Our sample of 160 participants included 120 children (6-13-years old) and 40 young adults (18-24 years). Participants performed a WM task with images of unique everyday items, presented at varying set sizes.…

To illuminate individual differences in the development of attention-deficit hyperactivity disorder (ADHD) symptoms in the general population, psychometric measures are needed that can capture general population-level symptom variation reliably, validly, and comparably from childhood through to the transition to adulthood. The ADHD subscale of the…

Objective: To provide additional information about clinical features associated with adult ADHD in patients diagnosed in childhood compared to those first diagnosed in adulthood. Method: We stratified a sample of adults with ADHD into patients diagnosed in childhood versus adulthood and compared demographic and clinical characteristics. Results:…

Ninety-seven children aged 4-11 (49 males, 48 females, mostly White) were given the opportunity to improve their problem-solving performance by devising and implementing a novel cognitive offloading strategy. Across two phases, they searched for hidden rewards using maps that were either aligned or misaligned with the search space. In the second…

Introduction: Mental health concerns have been noted to be highly prevalent for youth with intellectual disability (ID), with or without autism spectrum disorder (ASD). The purpose of the current study was to examine a Canadian sample of youth with ID, with or without ASD, to explore caregiver-reported percentages, predictors, and treatment…

Humans tend to avoid cognitive effort. Whereas evidence of this abounds in adults, little is known about its emergence and development in childhood. The few existing studies in children use different experimental paradigms and report contradictory developmental patterns. We examined effort-related decision-making in a sample of 79 five- to…

Understanding predictors of parents' willingness to vaccinate their children appears fundamental to promote vaccine acceptability, especially in a pandemic scenario. The present study aimed to investigate the role of conspiracy beliefs and absolutist thinking in parental attitude toward COVID-19 vaccine, and the predictive role of parents'…

Familiarity with technology has become a requirement for independent living, however there is limited information on technology access and use for people with Down syndrome (DS). The aim of this study is to describe technology, gaming, and social-media use in people with DS. Parents/caregivers (N = 220) of individuals with DS aged 5-35 years (49%…

Feeling inhibited and socially not at ease is reflected in the trait social inhibition (SI). SI is associated with psychopathology that arises in young adulthood, such as anxiety. We aim for a better insight into the genetic and environmental contributions to SI across the life span, and as such examine their contributions to SI stability and…
