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…

This study examined sibling behavior during polyadic family conflicts (involving three or more family members) by identifying operational conflict elements (i.e., roles, topic), power strategies, effective influence of power, and social domain argumentation. Polyadic conflict sequences (n = 210) were identified in 35/39 families with two siblings…

Sibling-directed teaching of mathematical topics during naturalistic home interactions was investigated in 39 middle-class sibling dyads at two time points. At time 1 (T1), siblings were 2 and 4 years of age, and at time 2 (T2), siblings were 4 and 6 years of age. Intentional sequences of sibling-directed mathematical teaching were coded for (i)…

Sibling relationships are argued to offer a rich social context for the development of young children's theory of mind (ToM). There is evidence that the presence of siblings, particularly older siblings, may promote preschoolers' ToM, but it has not been investigated among toddlers. This study evaluated differences in early manifestations of ToM…

Siblings' imitative behaviors were investigated in 39 middle-class dyads during six 90-min home sessions at both Time 1 (M age: older sibling = 4.4 years; younger sibling = 2.4 years) and Time 2 (2 years later). Although younger siblings imitated most often at T1 and T2, older siblings' imitation increased proportionally over time in comparison to…

Maternal and paternal teaching sequences directed to their preschool children in a naturalistic home environment were investigated. The sample included 37 middle-class sibling dyads, aged four and six, and both their mothers and fathers during ongoing interactions in the home for six 90-minute sessions. Sequences of parent-child teaching were…

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…

Using distributive justice theory as a framework, the purpose of the present mixed methods study was to determine whether parental differential treatment was present and if so, to what degree, in families of children with a developmental disability. Moreover, if present, we examined to what extent parental differential treatment impacted family…

Research Findings: Pretend play is an important context that supports young children's developing social-cognitive and creative abilities. The play behaviors of 70 sibling dyads in early and middle childhood were examined for the following indices of creativity in play: (a) play themes (set-up/organization, expected, creative), (b) object use…

Social-constructivist models of learning highlight that cognitive development is embedded within the context of social relationships characterized by closeness and intimacy (Vygotsky, 1978). Therefore, in contrast to prior research employing semistructured paradigms, naturalistic sibling-directed teaching was examined during ongoing interactions…

This study examined siblings' knowledge about the teaching concept during naturalistic teaching contexts, wherein children's communicative interactions were used as a gateway to their social understanding (Turnbull, Carpendale, & Racine, 2009). Participants included 39 sibling dyads (older age group, M[subscript age] = 6;4; younger age group,…

This study examined associations between parents' attributions of culpability and their observed interventions into sibling conflict. A total of 61 primary caregivers judged who was at fault for a sibling conflict and subsequently discussed the event with their two children (aged 4-10 years). Nonunilateral fault attributions (blaming both children…

This study examined associations between children's descriptions of sibling conflicts and their resolutions during a structured negotiation task. A sample of 58 sibling dyads (older sibling M age = 8.39 years, younger sibling M = 6.06 years) were privately interviewed about an actual conflict. Each child provided a narrative that was coded for…

Sibling relationship quality and social understanding (second-order false belief, conflict interpretation, and narrative conflict perspective references) were examined as unique and interactive correlates of sibling conflict behavior in 62 dyads (older M age = 8.39 years and younger M age = 6.06 years). High-quality relationships were associated…

Associations among sibling teaching strategies, learner behavior, age, age gap, gender, and social-cognitive skills (second-order false-belief and interpretive understanding of knowledge) were investigated in 63 sibling dyads in early and middle childhood. Two teaching tasks were introduced to the older sibling teacher: a teacher-directed task…
