The sibling relationship represents a unique bond characterized by a high degree of closeness and intimacy, which fosters teaching and learning. Two studies investigated associations between sibling-directed teaching, imitation as a learning strategy, and learner involvement during a semi-structured, video-taped construction task. Study 1 also…

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…

The purpose of the current study was to use the infant sibling design to explore whether proband traits of autism and ADHD could provide information about their infant sibling's temperament. This could help us to gain information about the extent to which infant temperament traits are differentially associated with autism and ADHD traits. We used…

Loneliness has been associated with several adverse psychosocial outcomes in childhood and adolescence. The present study aimed to investigate feelings of loneliness and social dissatisfaction in school-aged typically-developing (TD) siblings of children with an autism spectrum disorder (ASD). For this purpose, 118 siblings of children with ASD…

The present study examines the link between children's number of older siblings and their cognitive development, as measured by executive function (EFs) skills and verbal skills (VIQ) in a sample of 1,302 4-year-old children (54% boys) living in rural Pakistan. Specifically, we investigate whether the links between the number of older siblings and…

The two prior studies that have examined associations between the sibling constellation and theory of mind in autism spectrum disorder yielded discrepant findings. Thus, efforts to better understand the sibling-theory of mind link in autism spectrum disorder are necessary. This study examined a sample of prekindergarten- and kindergarten-aged…

This study was conducted to investigate the problematic behaviors of preschool students studying in public and private schools according to certain variables. The research was carried out with 300 students and their parents in private and public kindergartens. A demographic information form prepared by the researcher was used to collect the data.…

This analysis set out to identify associations between birth order and sexual health outcomes, focusing on family involvement in sex education and early sexual experiences. The third National Survey of Sexual Attitudes and Lifestyles is a stratified probability sample survey of 15 162 men and women aged 16-74 in Britain. Logistic regression was…

To illuminate how within-family differences in achievement may emerge, this study examined sibling experiences in middle childhood as predictors of sibling differences in college graduation. First- and second-borns from 152 families reported on their experiences with siblings and parents at ages 11.80 (SD = 0.56) and 9.22 (SD = 0.90),…

Naturalistic dyadic sequences of teaching and learning involving older and younger siblings were investigated in 39 middle-class dyads over a 2-year period in early childhood. Siblings were observed during ongoing interactions in the home setting for 6 90-min sessions at both Time 1 (older sibling "M" age = 4.4 years; younger sibling…

This study examined the association between observed cognitive sensitivity (CS) during family interactions and children's receptive vocabulary for older and younger siblings. Maternal and sibling CS was considered and associations were explored at the family-wide (between-family) and child-specific (within-family) levels of analysis. The…

The purpose of this study was to examine the influences of sibling constellation (sex and birth order) on creativity in the context of China's one-child policy (OCP) and Confucian culture (e.g., preference for male offspring). Participants were recruited from a public university in east China and were asked to complete 2 divergent thinking tests,…

This study examined the associations between sibling intimacy and conflict and youths' reports of risky behavior in a sample of adolescents ages 11-20. Participants were mothers, fathers, and sibling dyads in 393 families who were interviewed annually for 3, 4, or 5 years. Multivariate multilevel models tested longitudinal links between sibling…

The developmental science literature is riven with respect to (a) parental similar versus different treatment of siblings and (b) sibling similarities and differences. Most methodologies in the field are flawed or confounded. To address these issues, this study employed a within-family longitudinal design to examine developmental processes of…

Issues of equality and fairness and invasion of the personal domain, 2 previously identified topic areas of adolescent sibling conflict (N. Campione-Barr & J. G. Smetana, 2010), were examined in 145 dyads ("M" [subscript first-born] = 14.97, "SD" = 1.69 years; "M" [subscript second-born] = 12.20,…
