Research Findings: Empathy plays an important role in children's early social-emotional development. However, there are not many instruments available for measuring the different aspects/levels of empathy in preschool children. Moreover, few studies examined the validity of the existing measures for empathy in Chinese children. The present study…

Understanding distinctions between morality and conventions is an important milestone in children's moral development. The current meta-analysis integrated decades of social domain theory research (Smetana, 2006; Turiel, 1983) on moral and conventional judgments from early to middle childhood. We examined 95 effect sizes from 18 studies (2,707…

The relationship between motor skills and executive functions (EFs) is gaining prominence in the field of developmental psychology. However, evidence of the motor skills--EFs link in children with typical development is somewhat inconsistent and there has been no adequate attempt to evaluate it systematically across studies. In view of this, the…

Background: Employment is often central to individuals' lives. However, individuals with intellectual or developmental disabilities are often absent from the workplace, and little research has examined their interest in working. Aims: This study examined whether people with intellectual and/or developmental disabilities want jobs; why they do or…

Purpose: Current models of speech development argue for an early link between speech production and perception in infants. Recent data show that young infants (at 4-6 months) preferentially attend to speech sounds (vowels) with infant vocal properties compared to those with adult vocal properties, suggesting the presence of special "memory…

Associations between age, resting-state (RS) peak-alpha-frequency (PAF = frequency showing largest amplitude alpha activity), and thalamic volume (thalamus thought to modulate alpha activity) were examined to understand differences in RS alpha activity between children with autism spectrum disorder (ASD) and typically-developing children (TDC)…

We investigated whether selective discussion of autobiographical memory narratives would impact the quality of young people's recall of their nondiscussed memory narratives. Children (ages 8-9 years, n = 65) and adolescents (ages 13-15 years, n = 58) completed an adapted version of the retrieval-induced forgetting (RIF) paradigm for self-generated…

Previous research has shown that three comparison types are involved in the formation of students' academic self-concepts: social comparisons (where students compare their achievement with their classmates), dimensional comparisons (where students compare their achievement in different subjects), and temporal comparisons (where students compare…

Purpose: To study the relationship between actual motor competence (AMC) and perceived motor competence (PMC) in a large sample of 6- to 12-year-old children. Method: The AMC and PMC were measured (N = 1,669, 55% boys) with the Athletic Skills Track and the Physical Self-Confidence Scale, respectively. A variable-centered approach was applied to…

Purpose: Coarticulatory effects in speech vary across development, but the sources of this variation remain unclear. This study investigated whether developmental differences in intrasyllabic coarticulation degree could be explained by differences in children's articulatory patterns compared to adults. Method: To address this question, we first…

We leveraged nationally representative data from the Panel study of Income Dynamics-Child Development Supplement (N = 3,562) and the Early Childhood Longitudinal study (N = 18,174), to chart the development of working memory, indexed via verbal forward and backward digit span task performance, from 3 to 19 years of age. Results revealed nonlinear…

Background: This study investigated if subjective socioeconomic status (SSS) is related to self-rated health (SRH) and objective indicators of health in people with and without intellectual disability. Methods: Participants were 217 adults with, and 2350 adults without intellectual disability in Jersey. In the intellectual disability sample, 85…

Pretend play is an important, universal activity of early childhood, but research to date contains multiple inconsistencies in definitions and measurement of pretend play. To begin to resolve this issue, we conducted a first study of the multiple different behaviors of pretend play in the preschool years (3-5 years), and investigated their…

This study evaluates the psychometric properties of a verbal fluency task for potential use as an outcome measure in future clinical trials involving children with Down syndrome. Eighty-five participants attempted a modified version of the Neuropsychological Assessment of Children, Second Edition Word Generation Task at two time points. In the…

Recent evidence suggests that older adults experience momentary states of spending time alone (i.e., solitude) less negatively than younger adults. The current research explores the role of autonomy as an explanation mechanism of these age differences. Previous research demonstrated that solitude can be experienced positively when it is…
