Physical discipline among African American and European American mothers: Links to children's externalizing behaviors.

The aim of this study was to test whether the relation between physical discipline and child aggression was moderated by ethnic-group status. A sample of 466 European American and 100 African American children from a broad range of socioeconomic levels were followed from kindergarten through 3rd grade. Mothers reported their use of physical discipline in interviews and questionnaires, and mothers, teachers, and peers rated childrens externalizing problems annually. The interaction between ethnic status and discipline was significant for teacher- and peer-rated externalizing scores; physical discipline was associated with higher externalizing scores, but only among European American children. These findings provide evidence that the link between physical punishment and child aggression may be culturally specific.

Parenting stress among dual-earner mothers and fathers: Are there gender differences?

Stress in the parenting role has been found to be related to family functioning and parenting behavior. However, most research in this area has been conducted with clinical samples and has not compared parenting stress of mothers and fathers. In this study, 589 married couples with young children (1

Reading Skills in Early Readers Genetic and Shared Environmental Influences

The present study combined parallel data from the Northeast—Northwest Collaborative Adoption Projects (N2CAP) and the Western Reserve Reading Project (WRRP) to examine sibling similarity and quantitative genetic model estimates for measures of reading skills in 272 school-age sibling pairs from three family types (monozygotic twins, dizygotic twins, and unrelated adoptive siblings). The study included measures of letter and word identification, phonological awareness, phonological decoding, rapid automatized naming, and general cognitive ability. Estimates of additive genetic effects and shared environmental effects were moderate and significant. Furthermore, shared environmental effects estimated in twins were generally similar in magnitude to adoptive sibling correlations, suggesting highly replicable estimates across different study designs.

Sibling Relationships and Social-emotional Adjustment in Different Family Contexts

The aims of this study were to examine family type (nonstep, stepfather, stepmother, and single mother) and sibling type (full- and half-siblings) differences in sibling relationship quality (positivity and negativity), and to investigate links between sibling relationship quality and child externalizing and internalizing problems. The sample included 192 families with a 5-year-old target child and an older sibling. In addition, 80 of these families included a third older child. Mothers and the older siblings (8 years and older) completed questionnaires and interviews regarding conflict and support in their sibling relationships, and parents and teachers reported on each childs social-emotional adjustment. Sibling negativity (conflict, aggression) was highest in single-mother families and full-siblings were more negative than half- and stepsiblings. There was some evidence that sibling antagonism was associated with more child behavioral and emotional problems, but these effects were moderated by family type.

‘Speak roughly to your little boy’? Sex Differences in the Relations Between Parenting and Preschoolers’ Understanding of Mind

The present study explores relations between young children’s understanding of mind and parental emotional expression and disciplinary style, along with gender differences in these relations. Participants were recruited from a study of 125 same-sex twin-pairs (58% female; group mean age 5 43 months, SD 5 1 month). Each child received a comprehensive set of theory-of-mind tasks, and was filmed at home for 20 minutes in dyadic interactions with the primary caregiver, who was also interviewed about disciplinary strategies. Ratings of discipline and positive and negative parental affect and control were made from direct observation, from the interview, and from the videoed interactions. Strong correlations were found between family SES, parenting measures, and child verbal IQ and theory-of-mind score. However, regression analyses showed that parental behaviours were significant predictors of children’s theory-of-mind performance, even when sex, verbal IQ and family SES were taken into account. Sex differences in these relations were also identified; parental affect was especially salient for understanding of mind in girls, while discipline was more salient for boys. Taken together, these findings highlight the importance of individual differences in the proximal processes associated with early understanding of mind, and suggest that development in mental-state awareness is associated with distinct aspects of parenting for girls and boys.

The association between parental warmth and control in thirteen cultural groups

The goal of the current study was to investigate potential cross-cultural differences in the covariation between two of the major dimensions of parenting behavior: control and warmth. Participants included 1,421 (51% female) 7- to 10-year-old (M = 8.29, SD = .67 years) children and their mothers and fathers representing 13 cultural groups in nine countries in Africa, Asia, Europe, the Middle East, and North and South America. Children and parents completed questionnaires and interviews regarding mother and father control and warmth. Greater warmth was associated with more control, but this association varied widely between cultural groups.

Nonshared environmental processes in social‐emotional development: an observational study of identical twin differences in the preschool period

Differences in mothers’ parenting behaviors toward their identical twin preschoolers were examined to identify nonshared environmental processes in social-emotional development. The study included 62 pairs of 3½-year-old same-sex identical twins. Indicators of each child’s social-emotional development (temperament, prosocial behavior, behavior problems and noncompliance) and parenting environment (warmth and negativity, positive and negative control, responsiveness) were assessed using observers’, interviewers’, and parents’ ratings. Mothers treated their identical twins differently, and this differential treatment covaried in expected ways with identical twin differences in social-emotional adjustment. The twin who received more supportive and less punitive forms of parenting was also higher in positive mood and prosocial behaviors and lower in negative mood and behavior problems when compared to her or his twin.

Siblings, Parents, and Partners: Family Relationships within a Longitudinal Community Study

Links between sibling relationships, mother-partner, and parent-child relationships were studied in a longitudinal community sample of 3681 sibling pairs. Individual differences in sibling relationship quality were related to mother-partner affection and hostility assessed 4 years earlier, to contemporary parent-child negativity, and to indices of social adversity. Evidence for both direct and indirect pathways (via parent-child relations) linking mother-partner and sibling relations were found. Comparisons of prediction for non-stepfamilies and stepfather families showed similarities in patterns of association, but also differences: In stepfather families, mother-partner hostility was unrelated to parent-child negativity and sibling relationship quality. Both positivity and negativity towards young siblings decreased with the age of older siblings, and older sisters were more positive than older brothers.

Biological Systems and the Development of Self-Regulation: Integrating Behavior, Genetics, and Psychophysiology

Self-regulation is the ability to control inner states or responses with respect to thoughts, emotions, attention, and performance. As such, it is a critical aspect of development and fundamental to personality and behavioral adjustment. In this review, we focus on attentional, cognitive, and emotional control as we discuss the genetic mechanisms and brain mechanisms that contribute to individual differences in self-regulation. We conclude with a discussion of the implications for deviations in the development of this complex construct and suggestions for future research.

Measured Environmental Influences on Early Reading: Evidence From an Adoption Study

Many studies have examined the relationship between environmental processes and literacy outcomes. However, nearly all of this research has examined biologically related family members living together, thus confounding genetic and environmental influences. The purpose of this study was to address this issue using a sample of 262 adopted children and their families. Children were assessed in their homes on a 90-min battery of reading-related outcome measures. Parents reported on their educational attitudes, book reading practices, levels of involvement in homework, and their childrens interest in reading-related activities. Multilevel modeling results suggest that aspects of the family environment were associated with child reading-related outcomes, a finding that cannot be attributed to shared genes between parents and their children.
