Early relational origins of Theory of Mind: A two-study replication.

BACKGROUND: Research implies early relational factors - parental appropriate mind-mindedness (MM) and mutually responsive orientation (MRO) - as antecedents of children's Theory of Mind (ToM), yet the longitudinal path is unclear. Furthermore, little is known about the process in father-child relationships. In two studies of community families in a Midwestern state in United States, we tested a path from parental appropriate MM in infancy to parent-child MRO in toddlerhood to children's ToM at preschool age in mother- and father-child relationships, using comparable observational measures at parallel ages. METHODS: In Children and Parents Study (CAPS) of children born in 2017 and 2018, we collected data at 8 months (N = 200, 96 girls), 38 months, age 3 (N = 175, 86 girls), and 52 months, age 4.5 (N = 177, 86 girls). In Family Study (FS) of children born mostly in 2001, we collected data at 7 months (N = 102, 51 girls), 38 months, age 3 (N = 100, 50 girls), and 52 months, age 4.5 (N = 99, 49 girls). Parental MM (verbal comments aligned with the infant's psychological state) was observed in infancy, MRO (parent and child responsiveness to each other and shared positive affect) at age 3, and ToM (false belief tasks) at age 4.5. RESULTS: The findings supported the proposed indirect effects of parents' MM on children's ToM, mediated by MRO, for fathers and children in both studies, and for mothers and children, in CAPS. In FS, mothers' MM predicted MRO and ToM, but there was no mediation. CONCLUSIONS: This investigation, testing a path from MM to MRO to ToM in both mother- and father-child relationships in two longitudinal studies, adds to the literature that has described relations among those constructs but rarely integrated those in one model.

Elucidating mechanisms linking mothers' and fathers' mind-mindedness in infancy with children's self-regulation at early preschool age.

Extensive research has examined factors that contribute to individual differences in children's self-regulation (SR), a key social-emotional competence crucial to adjustment and mental health. Those differences become salient and measurable at late toddler age. In the CAPS (N = 200 community families), we examined mothers' and fathers' appropriate mind-mindedness (MM)-the ability to view the child as a psychological agent and correctly interpret his or her mental states-as a predictor of children's SR. MM was observed in parent-child interactions at 8 months, and SR was observed as the capacity for deliberate delay in standard tasks at 3 years. Reflecting a family system perspective, processes both within and across mother-child and father-child relationships were examined in one model. Parent-child mutual responsiveness, observed during interactions at 16 months, was modeled as a mediator of the paths from MM to SR. Fathers' MM had a significant, direct positive effect on SR; in addition, it enhanced mutual responsiveness in both father-child and mother-child dyads and promoted child SR through enhanced mother-child mutual responsiveness. The findings elucidate relatively poorly understood mechanisms linking parental MM in infancy with SR at early preschool age, highlight similarities and differences in the processes unfolding in mother-child and father-child relationships, and emphasize interparental dynamics in socialization.

Revisiting the debate on effects of parental power-assertive control in two longitudinal studies: early attachment security as a moderator.

Although there is a consensus that harsh, hostile, abusive discipline has uniformly adverse effects on children, scholars continue to debate implications of varying degrees of power assertion commonly used by most parents in daily interactions with young children. Attachment theory can inform this debate, as early attachment organization can serve as a catalyst, or moderator, of future socialization trajectories. Specifically, insecure attachment can amplify, whereas secure attachment can attenuate, detrimental effects of parental power-assertive control. In two community studies of mothers, fathers, and infants, Family Study (FS, N = 102), and Children and Parents Study (CAPS, N = 200), we assessed attachment security in infancy, parental power-assertive control at 4.5 years in FS and at 16 months in CAPS, and child positive orientation to the parent at 10 years in FS and at 3 years in CAPS. In both studies, fathers' power-assertive control undermined children's positive orientation toward the fathers, but only for children with less secure attachment histories in infancy (Attachment Q-Set in FS and Strange Situation Paradigm in CAPS), and not for those with more secure histories. The findings highlight indirect yet powerful, long-term effects of the early parent-child security, and suggest distinct processes in mother- and father-child dyads.

Infants' attachment security and children's self-regulation within and outside the parent-child relationship at kindergarten age: Distinct paths for children varying in anger proneness.

Research in developmental psychology has robustly documented positive associations between parent-child attachment security and the child's self-regulation (SR). This study of 102 community mothers, fathers, and infants contributes to that research by examining the role of attachment security, observed at 15 months using the Attachment Q-Set, as a predictor of two distinct aspects of self-regulation at 67 months: executive functioning (SR-EF), observed in abstract Stroop-like tasks (Day/Night & Snow/Grass and Tapping), and parent-related (SR-PR), observed within the context of the parent-child relationship in response to the mother's (SR-MR) and father's (SR-FR) requests and prohibitions. We also examined child anger proneness, observed at 7 months, as a moderator of those associations. In both mother-child and father-child dyads, child security predicted SR-EF; More secure children performed better in executive functioning tasks. In mother-child dyads, security also predicted SR-MR, but the effect was qualified by the interaction of security and anger proneness, such that the effect was significant only for highly anger-prone children. The effect reflected differential susceptibility: Compared with lower-anger peers, highly anger-prone children developed worse SR-MR if their security was low, but they developed better SR-MR if their security was high. The findings highlight the benefits of a nuanced approach to self-regulation, considering child individuality as interacting with security and examining processes in both mother-child and father-child dyads.

Negative internal working models as mechanisms that link mothers' and fathers' personality with their parenting: A short-term longitudinal study.

OBJECTIVE: Research on associations between parents' personality and parenting has a long history, but mechanisms that explain them remain unsettled. We examined parents' explicit and implicit negative internal working models (IWMs) of the child, assessed at toddler age, as linking parental personality and parenting. METHOD: Mothers and fathers from 200 community families provided personality self-reports (Neuroticism, Agreeableness, Empathy, and Anger/Hostility) when their children were infants. When children were toddlers, the explicit negative IWMs included self-reported low-mentalizing reflective functioning and resentment regarding the child. The implicit negative IWMs were coded as negative relational schemas from parental interviews. Parental positive affect, responsiveness, and power-assertive control were observed in lengthy interactions. Measures were parallel for mother- and father-child dyads. RESULTS: Mothers' implicit IWMs linked the association between low Empathy and more power-assertive control. Fathers' explicit IWMs linked the associations between high Neuroticism and low Agreeableness and lower responsiveness. Additionally, fathers' Agreeableness and Empathy directly predicted their parenting. Two paths (Agreeableness â†’ implicit IWMs, and explicit IWMs â†’ responsiveness) significantly differed between mothers and fathers. CONCLUSIONS: IWMs may link parental personality with parenting. The findings integrate and inform several bodies of literature in personality, social cognition, and developmental psychology.

Parent-child relationship and child anger proneness in infancy and attachment security at toddler age: a short-term longitudinal study of mother- and father-child dyads.

Early parent-child relationship and child negative emotionality have both been studied as contributors to attachment security, but few studies have examined whether negative emotionality can moderate effects of parent-child relationship on security and whether the process is comparable across mother- and father-child dyads and different security measures. In 102 community families, we observed parent-child shared positive affect and infants' anger proneness at 7 months, and attachment security at 15 months, using observer-rated Attachment Q-Set (AQS) and a continuous measure derived from Strange Situation Paradigm (SSP). For mother-child dyads, high shared positive affect and low anger proneness were associated with AQS security. Those effects were qualified by their interaction: Variations in shared positive affect were associated with security only for relatively more anger-prone children.  That effect reflected the diathesis-stress model. For father-child dyads, shared positive affect was associated with security. There were no effects for SSP security with either parent.
