In a national survey of U.S. adults, the number of close friends increased with age and 76% reported having three or more. However, 8% reported having none. There are limited parallel data for gifted learners but the survey provided an opportunity to compare the two groups. The numbers of close friends for gifted learners appears to increase from…

Young children often struggle to answer the question "what would have happened?" particularly in cases where the adult-like "correct" answer has the same outcome as the event that actually occurred. Previous work has assumed that children fail because they cannot engage in accurate counterfactual simulations. Children have…

Human beings naturally prefer and support ingroup members more than outgroup members, but to what extent do we "morally value" equal treatment to ingroups and outgroups? Across four preregistered studies, we examined the development of "group-transcendent fairness," that is, the moral endorsement of allocating resources equally…

The literature from inception to 2020 on the prevalence of epilepsy in autistic individuals was systematically reviewed and further explored by subgroup analyses and meta-regression models. This systematic review is registered with PROSPERO (CRD42020179725). A total of 66 studies from 53 articles were included. The updated pooled prevalence of…

We conducted a meta-analytic review of 53 studies published between 2000 and 2020 to quantify associations of parents' emotion regulation with parenting behavior and children's emotion regulation and internalizing and externalizing symptoms. Twelve meta-analyses, which included between 4 to 22 effect sizes (N from 345 to 3609), were conducted to…

This study investigated the factorial invariance of the Taiwan Wechsler Intelligence Scale for Children, Fifth Edition (WISC-V) across age and gender. A higher order five-factor model was tested on a nationally representative sample of 1,034 children aged 6-16 years. The results demonstrated full factorial invariance for Taiwan children of…

Two studies examined factors that predicted children's tendencies to match objects versus relations across scenes when no instruction was given. Study 1 examined a) age and b) nationality as a proxy for cultural differences in experiences with relations. The results showed that Chinese and U.S. children across ages all showed an initial bias to…

There is good evidence for an association between poor reading and anxiety, but the mechanisms responsible for this association are currently unknown. In this study, we used structural equation modeling of four large longitudinal databases from the United Kingdom (n = 7,870), the United States (ns = 8,001 and 7,160), and Australia (n = 768) to…

Developmental research during COVID-19 suggests that pandemic-related disruptions in family relationships are associated with children's mental health. Most of this research has focused on 1 child per family, thereby obfuscating patterns that are differentially operative at the family-wide (i.e., between-family) versus child-specific (i.e.,…

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…

The prevalence of autism/autism spectrum disorder (ASD) has been increasing across the world. Previous studies in Norway reported, that the prevalence rate for 0-10-year-old children is 1 in 166, and in the case of 11-year-old children it is 1 in 125. Moreover, another nationwide study discovered that 1 in 192 males and 1 in 695 females between…
