Purpose: We investigated how age and linguistic status affected listeners' ability to follow and comprehend 3-talker conversations, and the extent to which individual differences in language proficiency predict speech comprehension under difficult listening conditions. Method: Younger and older L1s as well as young L2s listened to 3-talker…

Substitute object pretense is one of the earliest-developing forms of pretense, and yet it changes considerably across the preschool years. By 3.5 years of age, children can pretend with substitutes that are highly dissimilar from their intended referents (Elder & Pederson, 1978), but even older children have difficulty understanding such…

Premature infants have significant risk for later behavior problems. This study examined growth trajectories of three problem behaviors across five developmental age points from preschool to early adulthood in a well-characterized sample of premature infants. The effects of neonatal risk, gender, and socioeconomic context were modeled on these…

Research on the characteristics shown by children who cyberbully others is scarce. The objective of this research is to know the variables that predict the involvement of youngsters in cyberbullying perpetration. The current study examined the relation between socio-cognitive and emotional variables and cyberbullying perpetration. It examined the…

The Cattell-Horn-Carroll (CHC) model is a comprehensive model of the major dimensions of individual differences that underlie performance on cognitive tests. Studies evaluating the generality of the CHC model across test batteries, age, gender, and culture were reviewed and found to be overwhelmingly supportive. However, less research is available…

The study of anthropomorphism in adults has received considerable interest with the development of the Individual Differences in Anthropomorphism Questionnaire (IDAQ; Waytz, Cacioppo, & Epley, 2010). Anthropomorphism in children--its development, correlates, and consequences--is also of significant interest, yet a comparable measure does not…

Background: Nonverbal communication deficits are characteristic of autism spectrum disorder (ASD) and have been reported in some later-born siblings of children with ASD (heightened-risk (HR) children). However, little work has investigated gesture as a function of language ability, which varies greatly in this population. Aims: This longitudinal…

Drawing on data from the 2011 Australian National Church Life Survey, this study was designed to assess the connection between religious affect (as a measure of Christian commitment) and global happiness (as a measure of personal well being) among a sample of 6,194 young churchgoers in Australia between the ages of 8 and 14 years, attending a…

The present study investigates inter-individual variation (linked to personality traits, multilingualism and sociobiographical variables) in the attitudes that 2035 multilinguals have of their own and others' foreign accent (FA). Data were collected through an online questionnaire. We found that multilinguals who were extraverted, emotionally…

This study examines the English vocabulary development of 43 very young child English as a foreign language (FL) learners (age 3.2-6.2) in China. They were tested twice for vocabulary breadth (reception and production) and semantic depth (paradigmatic and syntagmatic vocabulary knowledge). The development of the English vocabulary knowledge…

The developmental trajectory of the use of morphemes is still unclear. We investigated the emergence of morphological effects on visual word recognition in German in a large sample across the complete course of reading acquisition in elementary school. To this end, we analyzed lexical decision data on a total of 1,152 words and pseudowords from a…

Social exclusion and the behaviors, thoughts, and feelings it evokes in children were examined in the present study. Two forms of exclusion were identified: being rejected and being ignored. Surveys were administered to third and fifth grade students in a Northeastern suburb in the United States to see how children respond overall and if younger…

Category-based induction is a hallmark of mature cognition; however, little is known about its origins. This study evaluated the hypothesis that category-based induction is related to semantic development. Computational studies suggest that early on there is little differentiation among concepts, but learning and development lead to increased…

In the current research, we examined whether the Affect Misattribution Procedure (AMP) could be successfully adapted as an implicit measure of children's attitudes. We tested this possibility in 3 studies with 5- to 10-year-old children. In Study 1, we found evidence that children misattribute affect elicited by attitudinally positive (e.g., cute…

Mothers' mental-state references predict individual differences in preschoolers' false-belief (FB) understanding; less is known about the origins of corresponding variation in school-age children. To address this gap, 105 children completed observations with their mothers at child ages 2 and 6, three FB tasks and a verbal comprehension…
