We studied the effect of the number and characteristics of siblings (sex, age) on school achievement in several grades (kindergarten, first grade, and fifth grade), in two large French cohorts, with more than 16,000 children. Running linear mixed-effects models, we find that, independently of socioeconomic status, having more siblings is…

The potential influences on children's sharing decision caused by birth order and sibling age gap were examined. A third-party resource allocation task was adopted to examine five- to six-year-old children's sharing decision when they expected a protagonist to allocate resources between two recipients with different social relationships. Children…

Family and social networks are widely believed to influence important life decisions but identifying their causal effects is notoriously difficult. Using admissions thresholds that directly affect older but not younger siblings' college options, we present evidence from the United States, Chile, Sweden and Croatia that older siblings' college and…

This study investigated parents' and siblings' knowledge use during naturalistic teaching episodes in the home. Thirty-seven middle-class families were observed for six 90-minute sessions (siblings aged 4 and 6 years). Parent and sibling teaching sequences were coded for knowledge type (conceptual, procedural), conceptual subcategories (social…

To determine the status of sibling relations among first-born children aged 4-6 years and the influence of parenting style on sibling relationships among rural children, the Sibling Relationship Questionnaire and Parenting Style Questionnaire were used to survey 373 parents of children with sibling relationships who were between 4 and 6 years old…

Siblings play an important role in shaping the developmental trajectories of individuals with autism spectrum disorder. Having siblings has been associated with better social communication, non-verbal communication, and theory of mind abilities in autism spectrum disorder. However, little is known about the impact of siblings on adaptive skill…

Emotion understanding develops rapidly in early childhood. Firstborn children (N = 231, 55% girls/45% boys, 86% White, 5% Black, 3% Asian, 4% Latinx, Mage = 29.92 months) were recruited into a longitudinal study from 2004 to 2008 in the United States and administered a series of tasks assessing eight components of young children's emotion…

Inclusion of students with Autism Spectrum Disorder (ASD) in mainstream schools has a positive impact on their social and daily living behaviors. Our objective was to identify clinical and socio-demographic variables promoting or limiting inclusion in mainstream school through childhood and adolescence. The EpiTED study is a long-term,…

Background &aims: Language abilities of autistic children and children at elevated likelihood for autism (EL-siblings) are highly heterogeneous, and many of them develop language deficits. It is as of yet unclear why language abilities of autistic children and EL-siblings vary, although an interaction of multiple influential factors is likely…

An educational efficiency of an individual is strongly and bidirectionally connected with his/her self-perception determined by the unique family system and overall sense of social well-being. The role of parents is obvious and both theoretically and empirically well-researched. Nevertheless, academic self-efficacy may be significantly affected…

This study examines preschool children's play tendency and their prosocial behavior. The screening method was used in the study, and it was carried out with a total of 319 four- to six-year-old children who attended state kindergartens. "Children's Playfulness Scale" and "Child Prosocialness Scale" were used as data collection…

Background: Future planning has emerged as a global issue for families of individuals with intellectual and developmental disabilities due to the longer lives and limited long-term services and supports in the adult disability system. While it has received greater attention, most future planning studies only included parents of individuals with…

Socially savvy individuals track what they know and what other people likely know, and they use this information to navigate the social world. We examine whether children expect people to have shared knowledge based on their social relationships (e.g., expecting friends to know each other's secrets, expecting members of the same cultural group to…

This study compared sibling interactions between 24-month-old children and their older sibling with ASD (high-risk; n = 24) with 24-month-old children and their typically developing older sibling (low-risk; n = 32). First, high-risk sibling pairs showed lower levels of positive behaviour and younger siblings of children with ASD imitated their…

Against the backdrop of demographic ageing, university students increasingly face the need to reconcile studying and caring for an older person. Surprisingly little is known about the lives of caregiving students or the ways institutions of higher education can (or do) support them, however. Knowing more about this group is of importance from an…
