“The chug is coming through!” “There's two chuggas!”: A longitudinal study of the social function of imitation in children's play with siblings and friends

Imitation is argued to have an important affiliative function in social relationships. However, children's tendency to imitate different play partners during naturalistic play and associations with social understanding have been overlooked. We investigated the frequency and context of imitation in a longitudinal study of 65 focal children (T1: M age = 56.4 months, SD = 5.71) during play with their older or younger sibling and a friend in two separate play sessions. Children were observed again approximately 3 years later (T2: n = 46, M age = 94.6 months; SD = 6.6). We coded focal children's verbal and nonverbal imitation of their play partner, their partner's response to being imitated, the context in which imitation occurred (e.g., pretense), and the focal child's social understanding (i.e., mental state references). Verbal imitation occurred more often than nonverbal imitation and was used most often during the contexts of play negotiations and pretense. Although focal children's imitation of both their siblings and friends increased significantly over time, children imitated friends more than siblings at T1. All play partners responded positively (i.e., smiling, laughing) most often to being imitated. Associations between focal child imitation and mental state talk with friends at T2 approached significance. Our findings provide a deeper understanding of the nature of imitation during children's play interactions and support assertions that imitation is a process whereby children build affiliation, mutuality, and shared meanings in their relationships.     

I'm Telling! The Content, Context, and Consequences of Children's Tattling on their Siblings

Tattling on siblings was observed in 40 families with 2- and 4-year-old children. All but 5 children reported sibling misbehaviour to parents with younger siblings tattling largely to recruit parental help in resolving conflict issues, and older siblings tattling both in the context of conflict and merely to inform parents of their siblings' misbehaviour. Parents rarely reprimanded children for tattling, but either ignored it, or responded to information in tattlers' reports regardless of context or whether older or younger children tattled. Children did not tattle equally on all sibling transgressions, but emphasized physical aggression and property damage, issues that also elicited parental discipline. Tattling is discussed in relation to children's understanding of the dynamics and moral standards of family life.     

‘An Earthquake Shocked Up the Land!’ Children's Communication During Play With Siblings and Friends

The construction of shared meanings strategies (e.g., introductions, extensions) and use of internal state language (e.g., references to mental states) during play were examined across two relationship contexts (siblings and friends) in 65 focal kindergarten‐aged children (M age = 56.4 months; SD = 5.71 months). Strategies to construct shared meanings were associated with play session; specifically focal children employed introductions more often with their siblings whereas positive/neutral responses and prosocial strategies were used more frequently with their friends. Findings regarding birth order position indicated that older focal children were more likely to engage in non‐maintenance (e.g., negative) behaviors and explanations with their siblings whereas younger focal children employed extensions of play ideas more often with their siblings than friends. Associations between shared meaning strategies and internal state language were positively correlated across both relationship contexts, with more significant associations found in the sibling play session. Findings highlight the high level of sophisticated play interaction among children during play; these interactions were rich and varied and are discussed in light of recent research and theory.     

Power in Sibling Conflict during Early and Middle Childhood

Sources of power children use in sibling conflict during early and middle childhood were examined according to French and Raven's typology of power. Participants included 66 dyads with an older (M = 81.8 months, SD = 14.48 months) and younger (M = 56.2 months, SD = 13.03 months) sibling. Data based upon naturalistic observations were coded for conflict issues (object, procedure, and information), power types (coercive, information, and legitimate), power effectiveness (attempts and successes), and resolutions (win/lose and compromise). Siblings used coercive power in object issues and information power in procedural issues. Whereas younger siblings used legitimate power in procedural and object issues including win/lose and compromise outcomes, older siblings used coercive power in win/lose resolutions. Siblings did not differ in their effectiveness of power, but they were most effective when coercive power was employed. Findings are discussed in light of power theory and the development of conflict management skills.     

Understanding the Self Through Siblings: Self‐awareness Mediates the Sibling Effect on Social Understanding

This study addresses the role of sibling influence on social understanding in the second year of life, in a sample of families living in New Zealand who identify as Pacific Island (N = 43). We tested toddlers at 20 and 26 months on social understanding tasks, as well as their levels of self‐awareness on the Stipek self‐concept questionnaire. We hypothesized that the presence of siblings provides a rich resource from which to learn about the mind. There were significant differences in children's social understanding and self‐awareness as a function of having older siblings. Further analyses revealed that the relation between older siblings and social understanding was mediated by toddlers' level of self‐awareness.     

Family Talk about Internal States and Children's Relative Appraisals of Self and Sibling

This study investigated associations between preschoolers' conversations about internal states and their spontaneous appraisals of self and sibling. Thirty‐two preschoolers (M age = 3.9 years) were observed during naturalistic home interactions with mothers and younger siblings. Various features of mothers' and children's internal state language were coded. Children who talked about internal states to the baby and who talked more about the baby's perspective tended to appraise their sibling negatively relative to self. In contrast, mothers' references to internal states, as well as their promotion and encouragement of the child's own internal state talk, were negatively related to the differences between children's negative appraisals of self and sibling. These results support the social‐constructivist notion that the quality of children's interactions with family members is related to how they construe themselves in comparison to their siblings.     

Parent and Sibling Influences on the Quality of Children's Conflict Behaviours across the Preschool Period

Parent and sibling influences on children's development of conflict management strategies were examined. Data consist of naturally occurring, in‐home sibling disputes of 37 families at two time points. The siblings were approximately two and four years old at Time 1, and four and six years old at Time 2. Parents' and children's use of conflict strategies that reflect proactive autonomy assertions such as opposition and verbal and physical power were the focus of the current study. Results suggest that parents and siblings play an important role in shaping children's conflict behaviours over time. For instance, parents' reliance on unelaborated opposition to the child, and older siblings' increased use of physical power predicted decreases in younger siblings' ability to assert themselves during conflict. In addition, increased proportions of opposition from a younger sibling was associated with the older siblings using less verbal aggression and using more mature conflict strategies such as justifying their own behaviour to their younger sibling. As sibling conflict is a salient child rearing concern for parents, practical implications are discussed.     

Children's Physiological Regulation and Sibling Conflict as Correlates of Children's Conscience Development

Children's conscience, including the ability to experience guilt and engage in rule‐compatible behavior, develops across early childhood. The current study investigated whether within‐family variation in children's baseline respiratory sinus arrhythmia (RSA) and sibling conflict behavior were associated with individual differences in children's guilt and internalized conduct. Between‐family differences across sibling dyad gender compositions were also examined. A within‐family design that included 70 families with two siblings between the ages of 2 and 5 was utilized. Children's baseline RSA was measured while sitting quietly with their family. Mothers and fathers completed questionnaires that assessed siblings’ conflict behavior, guilt, and internalized conduct. Older siblings had higher levels of guilt and internalized conduct than younger siblings. Results from actor‐partner interdependence models indicated that there were no direct effects of children's baseline RSA. The interaction effects approached significance (p's ≤ .08) suggesting that older siblings’ conflict moderated the association between older siblings’ baseline RSA and both older and younger siblings’ guilt. In contrast, older siblings’ conflict was positively associated with older and younger siblings’ internalized conduct. Guilt and internalized conduct also differed for older and younger siblings in different dyad gender compositions. The results underscore the need for greater clarity regarding the function that siblings serve in promoting children's moral development during early childhood.     

Children's Family Relationships Between Two and Five: Developmental Changes and Individual Differences

Developmental changes in children's relationships with their mothers and older siblings between 33 and 69 months of age were investigated in a longitudinal study of 47 families, through an examination of family conversations and affect expressed during unstructured home observations. Mother-child interaction decreased and sibling interaction increased markedly over the period. The prominence of reflective commentary in children's discourse increased while self-interested moves decreased with both partners; however differences in emotional expression and in patterns of change in the two relationships were marked, with more positive and negative emotion and play with siblings. Individual differences in the trajectory of these changes were correlated with early differences in social understanding, and with SES. The association between children's developing social understanding and these changes in relationships is discussed.     

Getting Along or Getting Your Own Way: The Development of Young Children's Use of Argument in Conflicts with Mother and Sibling

The development of children's use of argument in conflicts with their mother and sibling during their fourth vear, a period of marked changes in their understanding of others, was studied in 49 children observed at home with their mothers and siblings at 33 and 47 months. Children's use of reasoned argument in conflict increased: however, the proportion used for conciliation and compromise decreased, and children used justifications increasingly to support their own position. Mothers, hut not siblings, changed in parallel to the children over this period. Both the initiator of a dispute and children's expression of affect were related to children's use of argument; children used less reasoned argument when they were upset. Results are discussed in relation to differences in the development of children's relationships with mother and sibling and the importance of the link between affective expression and the use of argument in family disputes.     

Siblings as Confidants: Emotional Understanding, Relationship Warmth, and Sibling Self-Disclosure

Associations among (a) self-disclosures between early adolescent siblings, (b) emotional understanding, and (c) relationship warmth were investigated. Grade 5–6 children (M age = 11.5 years) were interviewed concerning the incidence of disclosures to closest-in-age siblings (20 = older, 20 = younger), feelings regarding disclosing (or not), and sibling relationship quality. Warmth was measured with the Sibling Relationship Questionnaire (Furman & Buhrmester, 1985) and emotional understanding was assessed with the Hypothetical Relationships Picture Task (adapted from Schneider, 1989, & Aquan-Assee, 1992). Hierarchical multiple regressions indicated self-disclosure was positively associated with feeling good about sharing and negatively associated with reports of not trusting or not receiving emotional support from their sibling. Sibling relationship warmth was a key characteristic associated with both emotional understanding and self-disclosure; female target children demonstrated greater emotional understanding. Warmth, but not emotional understanding, was associated with self-disclosure. Findings are discussed in light of the importance of links between affective relationships and children's social-emotional understanding.     

Children's Interpretations of Ambiguous Provocation From Their Siblings: Comparisons With Peers and Links to Relationship Quality

This study investigated how six‐ to eight‐year‐old children interpret ambiguous provocation from their siblings. In particular, we examined how children's attributions of their siblings' intent (1) differed from those for their peers, (2) varied as a function of the structural features of the sibling relationship, and (3) were associated with the affective qualities of the sibling relationship. A total of 121 children were presented with ambiguous provocation scenarios in which three groups of agemates were described as the perpetrators of harm (siblings, friends, and disliked peers). Scenarios were designed to assess children's attributions of hostile, instrumental, and accidental intent. Children attributed more hostile intent to disliked peers than to siblings and less hostile intent to friends than to siblings. Accidental and instrumental intent attributions were equally likely for friends and siblings but less common for disliked peers. Children attributed more hostile intent to older siblings, and more instrumental intent to laterborn siblings who were chronologically younger. Children's attributions of siblings' intent were related to both parents' and children's reports of the affective features of siblings' interactions. Results provide new insight into how children's construals of others' actions are grounded in the unique features of their relationships with particular interaction partners.     

A prospective study of adolescent mothers’ social competence,children's effortful control and compliance and children's subsequent developmental outcomes

Previous work has established that caregiver and child temperamental characteristics are associated with child compliance. Given the critical role that parents play in this process, and that children of teen mothers are at risk for poorer developmental outcomes, it is important to understand the development of compliance in the context of at‐risk parenting such as adolescent motherhood. The current study examined child compliance (Wave 5; W5) as a mediator of the association between adolescent mothers’ social competence (Wave 4; W4) and children's behavioral and academic outcomes (Wave 6; W6), and whether this mediation varied depending on children's effortful control (W4) in a sample of 204 Mexican‐origin adolescent mothers (M_age at W4 = 19.94, SD = .99) and their children (M_age at W4 = 36.21 months, SD = .45). Adolescent mothers reported on their own social competence and their children's effortful control and externalizing problems; compliance was assessed using observational methods; and academic readiness was assessed using standardized developmental assessments. Findings based on structural equation modeling revealed that adolescent mothers’ social competence was positively related to children's compliance among children with high effortful control, but not among those with low effortful control. Moreover, child compliance mediated the longitudinal association between adolescent mothers’ social competence and child externalizing problems and academic readiness. Discussion focuses on the importance of considering the role of child temperament in understanding how adolescent mothers’ social competence is subsequently associated with children's social and academic adjustment.     

The influence of an older sibling on preschoolers’ lie‐telling behavior

In the present study, children’s (2‐ to 5‐years old) lie‐telling was examined in relation to theory of mind (first‐order false belief understanding), executive functioning (measuring inhibitory control in conjunction with working memory), and presence of siblings in the home (no siblings vs. siblings; younger siblings vs. older siblings).  Lie‐telling was observed using a temptation resistance paradigm. Overall, of the 152 (74.9%) children who peeked at the toy, 73 (48%) lied during the temptation resistance paradigm. Children with higher scores on measures of first‐order false belief understanding, and measures that relied on inhibitory control, were more likely to lie compared to their truthful counterparts.  Additionally, children with older siblings were more likely to lie to the research assistant, and this relationship was independent of performance on cognitive tasks. Overall, results demonstrate that having an older sibling has an independent, direct effect on the development of young children’s lie‐telling abilities, irrespective of cognitive ability. These findings support the argument that lie‐telling is a behavior that is facilitated by both cognitive and social factors.     

Older sibling contribution to younger children's working memory and cognitive flexibility

We used structural equation modeling in the Early Childhood Longitudinal Study—Kindergarten Cohort (N = 17,020) to explore the influence of having an older sibling on kindergarten‐age focal children's cognitive self‐regulation. In model 1, we tested how having a sibling who is generally older than the focal child contributes to the focal child's working memory (WM) and cognitive flexibility (CF) upon entering kindergarten. In model 2, we assessed the contribution to the focal child's kindergarten WM and CF of having an older sibling in a non‐proximal age range (age 12–18) or not having siblings relative to having an older sibling in a proximal age range to the focal child (up to age 11). In model 3, we considered the contribution of having an older sister, an older brother, or both an older sister and an older brother of any age. Having an older sibling in general was associated with increased kindergarten WM, whereas having an older sister was related to increased WM and CF. Compared to having a proximal older sibling, having no siblings and having a non‐proximal older sibling were related to decreased WM and CF. Findings have implications for involving siblings in family interventions in early childhood.     

Competing Processes of Sibling Influence: Observational Learning and Sibling Deidentification

Although commonly cited as explanations for patterns of sibling similarity and difference, observational learning and sibling deidentification processes have rarely been examined directly. Using a person‐oriented approach, we identified patterns in adolescents' perceptions of sibling influences and connected these patterns to sibling similarities and differences and sibling relationship qualities. Participants included two adolescent‐age siblings (firstborn age M = 16.39, second‐born age M = 13.78) from 171 maritally intact families. Two‐stage cluster analyses revealed three sibling influence profiles: modeling, deidentification, and non‐reference. Analyses revealed differences in the correlations between firstborn and second‐born siblings' personal qualities across the three groups and differences in the sibling relationship qualities of younger siblings who reported modeling vs. those who reported deidentifying from their older siblings. Discussion focuses on refining the study of sibling influence processes.     

Differing Domains of Actual Sibling Conflict Discussions and Associations with Conflict Styles and Relationship Quality

Four types of sibling conflict were identified in actual adolescent sibling discussions: equality and fairness, invasion of the personal domain, intrinsic harm, and relationships. Older [M = 14.97, standard deviation (SD) = 1.69 years] and younger siblings (M = 12.20, SD = 1.90 years) from 144 dyads discussed conflicts during a semi‐structured conflict task. Trained observers coded the topics discussed, and separate observers rated their conflict styles, whereas siblings rated their relationship quality. The proportion of conflicts of each domain differed by dyadic gender composition. Equality and fairness conflicts (and invasion of the personal domain conflicts for sister–sister pairs) were discussed the most frequently whereas intrinsic harm conflicts were associated with destructive conflict styles. Siblings' discussions of conflicts involving intrinsic harm were associated with older siblings' reports of negative relationship quality. The associations between these conflict topics and negative relationship quality were mediated by the siblings discussing the conflicts in destructive ways.     

Sibling Jealousy in a Triadic Context with Mothers and Fathers

The current study focused on jealousy between toddler and preschool siblings. Sixty-two families participated in triadic interaction sessions, in which mothers and then fathers were instructed to focus on one child (older sibling or toddler) while encouraging the other child to play with other toys in the room. Results indicated that child jealousy reactions differed between mothers and fathers, and parents behaved differently with older and younger siblings. Although older and younger siblings showed jealousy, older children were better than their toddler-age siblings at regulating jealousy responses and engaging in focused play. Further, younger siblings showed differences in jealous behavior when interacting with each parent, whereas older siblings showed somewhat greater behavioral consistency across parents, indicating internalization of emotion regulation style. Mothers expressed more happiness than fathers, and parents responded differently to older versus younger siblings' behaviors. Findings underscore the importance of examining emotion regulation processes within salient family relationships and of considering sibling interaction as a socialization context in which young children learn to negotiate emotional challenges.     

Does It Matter if Preschool Children and Mothers Discuss Positive vs. Negative Events During Reminiscing? Links with Mother‐reported Attachment,Family Emotional Climate,and Socioemotional Development

The purpose of the study was to examine the differential relations between mother–child reminiscing about a positive emotional event vs. a negative emotional event and attachment security, family climate, and young children's socioemotional development. Fifty preschool children (M age = 50.69 months, SD = 4.64) and their mothers completed two reminiscing conversations at the laboratory, which were coded for emotion‐laden discourse, affect, and elaboration, and children completed measures of emotional understanding and representations of relationships. At their homes, mothers completed the attachment Q‐sort and the self‐report family inventory. Both attachment security and family climate were related to the quality of mother–child affect and maternal elaboration during both positive and negative reminiscing conversations. Attachment security and family climate, however, were principally related to discussion of emotion during the negative event discussions. In addition, it was mother–child reminiscing about the negative emotional event that was associated with high levels of children's socioemotional development.
