Increased life expectancy in persons with Down syndrome (DS) is associated with premature age-related changes. The aim of this study was to assess auditory function in adults with DS and to evaluate the prevalence of hearing loss in this population. Audiometric tests were performed in 72 adults with DS (mean age 37.3 ± 10.1 years, 51.4% females).…

Children use pronouns in their speech from the earliest word combinations. Yet, it is not clear from these early utterances whether they understand that pronouns are used as substitutes for nouns and entities in the discourse. The aim of this study was to examine whether young children understand the anaphoric function of pronouns, focusing on the…

There is renewed interest in person-centered approaches to understanding the structure of temperament. However, questions concerning temperament types are not frequently framed in a developmental context, especially during infancy. In addition, the most common person-centered techniques, cluster analysis (CA) and latent profile analysis (LPA),…

Purpose: This study examined intelligibility of conversational and clear speech sentences produced in quiet and in noise by children, young adults, and older adults. Relative talker intelligibility was assessed across speaking styles. Method: Sixty-one young adult participants listened to sentences mixed with speech-shaped noise at -5 dB…

A large body of research work demonstrates the importance and effectiveness of adapting a learning game to its players. This process is driven by understanding the differences between individuals in terms of abilities and preferences. One of the rather interesting but least explored approaches for understanding individual differences among…

The Dimensional Change Card Sort (DCCS) task is a widely used measure of preschoolers' executive function. We combined data for 3,290 3-year-olds from 37 unique studies reporting 130 experimental conditions. Using raw pass/fail counts, we computed the pass rates and chi-squared value for each against chance (50/50) performance. We grouped data…

Secondary data analyses from the Longitudinal Study of Australian Children Kindergarten cohort were performed to understand any alterations in pubertal timing in Autism Spectrum Disorder (ASD) in a population sample. Timing of parent-reported pubertal events (ages 8-9, 10-11, 12-13 years), and self-report (14-15 years; N = 3454 no ASD, N = 94 with…

Data from 949 children and adolescents with intellectual disability ages 5 to 16 for whom the Supports Intensity Scale-Children's Version-Catalan Translation was completed was used, in combination with data from the U.S. standardization sample, to examine measurement invariance and latent differences in the Catalonian sample. Results suggest that…

Naturalistic goal-directed behaviours require the engagement and maintenance of appropriate levels of cognitive control over relatively extended intervals of time. In two experiments, we examined preschool children's abilities to maintain top-down control throughout the course of a sequential task. Both 3- and 5-year-olds demonstrated good…

In conceptualizing vulnerability, it is common for researchers to assume that some participants are more vulnerable on the basis of their membership of a particular group or because they exhibit particular characteristics. Older people are often viewed as inherently more vulnerable by ethics committees and the ethical guidelines committees…

Guilt serves vital prosocial functions: It motivates transgressors to make amends, thus restoring damaged relationships. Previous developmental research on guilt has not clearly distinguished it from sympathy for a victim or a tendency to repair damage in general. The authors tested 2- and 3-year-old children (N = 62 and 64, respectively) in a…

Adults exhibit strong preferences when framing symmetrical relations. Adults prefer, for example, "A zebra is like a horse" to "A horse is like a zebra," and "The bicycle is near the building" to "The building is near the bicycle." This is because directional syntax requires more typical or prominent items…

Emerging executive control supports greater autonomy and increasingly adaptive behavior during childhood. The present study addressed whether children's greater monitoring of how they engage control drives executive control development. Gaze position was recorded while twenty-five 6-year-olds and twenty-eight 10-year-olds performed a self-paced…

Data from the standardization sample of the Woodcock-Johnson Psychoeducational Battery--Third Edition (WJ III) Cognitive standard battery and Test Session Observation Checklist items were analyzed to understand the relationship between g (general mental ability) and test session behavior (TSB; n = 5,769). Latent variable modeling methods were used…

Mobile learning, which is widely used in educational settings during the COVID-19 pandemic, will continue playing a critical role in learning environments in the future. Since the successful implementation of mobile learning in education is largely based on users' acceptance of these technologies, it is essential to understand the factors…
