This study recruited 428 Singaporean children at risk of math learning difficulties (MLD; Mage  = 83.9 months, SDage  = 4.35 months; 41% female). Using a factor mixture model that considered both quantitative and qualitative differences in math ability, two qualitatively different groups were identified: one with generalized difficulties across different math skills and the other with more focal difficulties in arithmetic fluency. Reading, working memory capacity, and numeracy (number line estimation skills and numerical discrimination) uniquely explained group membership...

This study investigates the impact of evidentiality on source monitoring and the impact of source monitoring on false belief understanding (FBU), while controlling for short-term memory, age, gender, and receptive vocabulary. One hundred (50 girls) monolingual 3- and 4-year-olds from Turkey and the UK participated in the study in 2019. In Turkish, children's use of direct evidentiality predicted their source monitoring skills, which, in turn, predicted their FBU. In English, FBU was not related to source monitoring...

Salient practices in the parenting literature-support and control-have seldom been applied to understanding lesbian, gay, bisexual, transgender, queer, or questioning (LGBTQ) youth mental health. We examine associations among perceived parental social support, psychological control, and depressive symptoms for LGBTQ youth in the United States (n = 536; Mage  = 18.98; 48.1% women; 25.2% Black or African American; 37.1% Hispanic or Latino/a/x). Data were collected in 2011-2012. Results indicated joint effects of social support and psychological control predicting youth depressive symptoms...

Learning about emotions is an important part of children's social and communicative development. How does children's emotion-related vocabulary emerge over development? How may emotion-related information in caregiver input support learning of emotion labels and other emotion-related words? This investigation examined language production and input among English-speaking toddlers (16-30 months) using two datasets: Wordbank (N = 5520; 36% female, 38% male, and 26% unknown gender; 1% Asian, 4% Black, 2% Hispanic, 40% White, 2% others, and 50% unknown ethnicity; collected in North America; dates of data collection unknown) and Child Language Data Exchange System (N = 587; 46% female, 44% male, 9% unknown gender, all unknown ethnicity; collected in North America and the UK; data collection dates, were available between 1962 and 2009)...

Linking classroom quality to separate domains of child development might neglect the transactional interactions across developmental domains. This research utilized latent profiles across academic and social-emotional development to explore which aspects of classroom quality can predict children's profiles at the classroom level. Data were drawn from 96 preschool classrooms and 547 children (3-5 years old) in China in 2020. Multilevel latent profile analysis identified three profiles (entitled low-, average- and high-level development at the individual level), and two classes (entitled average and below-, average and above) at the classroom level...

Studies suggest prenatal cannabis exposure is associated with mood/behavioral problems in children. However, it is unclear if targeting modifiable domains like sleep behaviors would improve outcomes in exposed youth. Using a causal inference framework, the effect of changing sleep-hours on changing internalizing/externalizing problems in children was examined using the Adolescent Brain Cognitive Development™ study baseline (ages 9-10; collected during 2016-2018) and year-1 follow-up data (N = 9825; 4663 female; 5196 white)...

This paper used cross-lagged panel models to test the longitudinal interplay between maternal cultural socialization, peer ethnic-racial discrimination, and ethnic-racial pride across 5th to 11th grade among Mexican American youth (N = 674, Mage  = 10.86; 72% born in the United States; 50% girls; Wave 1 collected 2006-2008). Maternal cultural socialization predicted increases in subsequent youth ethnic-racial pride, and youth ethnic-racial pride prompted greater maternal cultural socialization...

We compared the reading development of 77 deaf and hard-of-hearing (DHH) Japanese children, aged 5-7 (40 females), with 139 of their hearing peers (74 females) in 2018. We assessed each group's phonological awareness (PA), grammar, vocabulary, and reading of hiragana (Japanese orthography children learn first). DHH children showed significant delays in grammar and vocabulary but only a slight delay in PA. Younger DHH children scored better than their hearing peers in reading. Although PA predicted reading for hearing children, reading predicted PA for DHH children...

Anti-bullying interventions often assume that knowing how it feels to be bullied increases empathy for victims. However, longitudinal research on actual experiences of bullying and empathy is lacking. This study investigated whether within-person changes in victimization predicted changes in empathy over 1 year using random-intercept cross-lagged panel models. Self- and peer-reported victimization, and cognitive and affective empathy for victims were measured in a sample of 15,713 Finnish youth (Mage  = 13...

People sometimes commit 'egocentric errors', failing to ignore their own perspective when interpreting others' communication. Training imitation-inhibition, when participants perform the opposite action from another person, facilitates subsequent perspective-taking in adults. This study tested whether imitation-inhibition training also facilitates perspective-taking in 3- to 6-year-olds, an age where egocentric perspective may be particularly influential. Children participated in a 10-min imitation-inhibition, imitation, or non-social-inhibition training (white, n = 25 per condition, 33 female, period: 2018-2021), then the communicative-perspective-taking Director task...

Handedness has been studied for association with language-related disorders because of its link with language hemispheric dominance. No clear pattern has emerged, possibly because of small samples, publication bias, and heterogeneous criteria across studies. Non-right-handedness (NRH) frequency was assessed in N = 2503 cases with reading and/or language impairment and N = 4316 sex-matched controls identified from 10 distinct cohorts (age range 6-19 years old; European ethnicity) using a priori set criteria...

Interactions with peers are fundamental to socio-cognitive development, but assessing peer interactions in standardized experiments is challenging. Therefore, researchers commonly utilize puppetry to simulate peers. This Registered Report investigated urban German children's (AgeRange  = 3.5-4.5 years; N = 144; 76♀) mind ascriptions and social cognition to test whether they treat puppets like peers, adults, or neither. Children attributed less mind properties to puppets than peers or adults...

This study investigated associations between kindergarten teachers' (N = 208) depressive symptoms and students' (Ghanaian nationals, N = 1490, Mage  = 5.8) school-readiness skills (early literacy, early numeracy, social-emotional skills, and executive function) across 208 schools in Ghana over one school year. Teachers' depressive symptoms in the fall negatively predicted students' overall school-readiness skills in the spring, controlling for school-readiness skills in the fall...

Why do infants and toddlers prefer helpers? Four experiments (conducted from 2019-2022; n = 136, 66% White, 15% Asian, 4% Black, 2% Hispanic/Latino, 13% multiracial, majority USA) investigated whether infants and toddlers favor agents whose actions allow others to achieve their goals. In the key experiment, 8-month-old infants and 15-month-old toddlers viewed a protagonist who tried and failed to open a box that contained a toy while two other agents (helpers) observed; then the toys were exchanged and the helpers opened different boxes...

Since robots are becoming involved in children's lives, it is urgent to determine how children perceive robots. The present study assessed whether Japanese 5-year-olds care about their reputation when interacting with a social robot. Children were given stickers and asked to divide them between themselves and an absent recipient. Results revealed that children (N = 112, 55 boys, 57 girls) strategically shared more stickers when being watched by a social interactive robot than by an attentional but non-interactive robot or a still robot...

Following 602 Chinese twin pairs (48% male, all Han ethnicity) from primarily lower-than-average socioeconomic status families from early to mid-adolescence (Ms  = 12 and 15 in 2006 and 2009), this study investigated gene-environment interplay between perceived parental supervision, peer drunkenness, and adolescent alcohol initiation. For alcohol initiation, shared environmental influences were initially negligible but became substantial. Genetic factors largely explained the links between both correlates with alcohol initiation...
