Longitudinal course and family correlates of sibling relationships from childhood through adolescence

Changes in sibling intimacy and conflict were charted from middle childhood through adolescence, and family structure and relationship correlates of change were examined. Participants were mothers, fathers, and firstborn (M=11.82 years at Time 1) and secondborn (M=9.22 years) siblings from 200 White, working/middle class, 2-parent families. Sibling intimacy was highest for sisters, stable over time for same-sex dyads, and showed a U-shaped change pattern in mixed-sex dyads. Sibling conflict declined after early adolescence at the same time (but at different ages) for firstborn and secondborns. Maternal acceptance covaried positively with sibling intimacy, and father-child conflict covaried positively with sibling conflict over time; fathers' marital love was linked to sibling intimacy in a pattern suggestive of compensation.     

A latent transition analysis of academic intrinsic motivation from childhood through adolescence

A longitudinal modeling approach was utilized to determine the existence of latent classes with regard to academic intrinsic motivation and the points of stability and transition of individuals between and within classes. A special type of latent Markov Chain model using Mplus was fit to data from the Fullerton Longitudinal Study, with academic intrinsic motivation measured from ages 9 through 17. Model fit using the Bayesian Information Criterion index was examined. The best fit involved a 3-class model, with classes designated as motivationally gifted, intermediate, and at-risk. Transitions between classes occurred mainly during childhood, whereas stability ensued by age 13. Methodological contributions are discussed, as well as theory and applications of the findings with regard to academic intrinsic motivation.     

A longitudinal study of negative emotional states and adjustment from early childhood through adolescence

The relations among various negative emotional and behavioral characteristics (e.g., aggression, anxiety, undercompliance, depressive mood) and adjustment were examined through use of data from the 31-year-old New York Longitudinal Study. 75 white, middle-class children were rated on these negative characteristics from infancy to adolescence. Measures of family, peer, and personal adjustment were also obtained. Because of the longitudinal nature of the data, we were able to use structural equation models to address the following questions: (1) How stable are these negative behaviors from early life through adolescence? (2) What is the degree of relation between these emotional characteristics and adjustment in childhood and adolescence? and (3) To what degree do these emotional characteristics differentially predict multiple adjustment dimensions in adolescence? 2 factors of negative emotional behavior, labeled as Aggression and Affect, respectively, were identified in early and late childhood and were found to have relatively high stability of individual differences. Aggression significantly predicted adolescent maladjustment, whereas Affect had no independent prediction of maladjustment. Moreover, emotional problems provided better prediction of adolescent adjustment problems than did earlier childhood adjustment ratings.     

Effects of mathematics learning through children's literature on math achievement and dispositional outcomes

The purpose of this study was to analyze the effectiveness of using children's literature to promote mathematics learning. Fifty-seven kindergarteners were randomly assigned to either a control group or an experimental group. The experimental group received mathematics related storybook reading and discussion time and played with mathematics materials that were related to the storybook content during free play. The control group had ordinary storybook reading time and played with mathematics materials unrelated to the storybook content. The Learning Readiness Test and the Early Mathematics Achievement Test were administered. Four mathematics tasks were also given to compare the mathematics achievement of the two groups. The children's choice of favorite corners, the time spent, and the number of children who played in the mathematics corner were investigated also to measure children's disposition toward doing mathematics. The results showed that more children in the experimental group liked the mathematics comer, chose mathematics tasks, and spent more time in the mathematics corner. Furthermore, the experimental group did significantly better than the control group in the classification, number combination, and shape tasks, and there were qualitative differences in the content analysis.     

The timing of executive function development is associated with growth in math achievement from preschool through second grade

We examined whether the timing of executive function (EF) development was associated with growth in children's math achievement across eight measurement occasions from preschool through second grade. Using a prospective longitudinal sample of 351 children, we found that children who developed EF later, entered preschool with the lowest levels of math performance and did not catch-up to their intermediate or early EF developing counterparts despite exhibiting a similar math growth rate through second grade. This trend was also observed after controlling for children's biological sex, early language skills, and socioeconomic background. These findings suggest that developing EF late might place children at a unique risk for math difficulties independent of important child and family level characteristics and can provide insights for instructional strategies that take into account differences in children's EF development.     

Saving in childhood and adolescence: Insights from developmental psychology

This paper addresses variables related to child and adolescent saving and explains the development of skills and behaviors that facilitate saving from an economic socialization perspective. References are made to the differences between the economic world of children, adolescents, and adults as well as to existing theories of saving. Children's and adolescents’ ability and willingness to save are looked at, taking into account the social context of the family and general child and adolescent development. The paper concludes with directions for future research in this area.     

Co-development of math anxiety,math self-concept,and math value in adolescence: The roles of parents and math teachers

Despite the well-documented negative implications of math anxiety on math learning, a scarcity of theory-guided, long-term longitudinal research limits knowledge about how math anxiety develops over time. Guided by the Control-Value Theory of Achievement Emotions (Pekrun, 2006), the present study addresses this gap by examining (1) how math anxiety develops in tandem with the development of control and value appraisals across secondary schooling, and (2) how these three constructs co-develop in relation to characteristics of home and school contexts. We used growth mixture modeling to investigate how math anxiety, math self-concept (a frequently examined indicator of control appraisal), and math utility value (one dimension of math value) develop in parallel in a sample of 3116 adolescents, who were assessed annually across middle and high school. We identified three trajectory classes: a stable class, characterized by stably modest math anxiety, high math self-concept, and high math utility value, a linear change class, characterized by increasing math anxiety and decreasing math self-concept and utility value, and a fluctuating class, characterized by curvilinear changes in math anxiety, math self-concept, and math utility value. Parental academic support and teacher bias differentiated the stable class from the fluctuating class at the transition to middle school, and from the linear change class at the transition to high school. Our findings point to the heterogeneous contributions of control and value appraisals towards the development of math anxiety and highlight the importance of investigating multiple dimensions of the socio-ecological context at different stages of math anxiety development.     

Decreasing the SES math achievement gap: Initial math proficiency and home learning environments

Many children in the U.S., particularly those from low socioeconomic status (SES) backgrounds, do not develop sufficient math skills to be competitive in today's technological world. We utilized a mediation/moderation framework and the ECLS-K dataset to investigate factors that can decrease the SES-related math achievement gap in kindergarten. Starting kindergarten proficient in math and experiencing a supportive home learning environment significantly decreased SES achievement differences. Proficiency in math at the start of kindergarten accounted for the greatest decrease in the SES-math achievement gap. Findings support the importance of comprehensive and multi-contextual approaches targeted to families and schools for improving children's exposure to math-relevant experiences.     

Social cognition and competence in middle childhood

2 aspects of social cognition--interpersonal understanding and means-ends problem-solving ability--were evaluated in fourth- to seventh-grade children and related to sex, age, IQ, social class, and multiple dimensions of competence. Results indicated that both social-cognitive components were significantly correlated with IQ, while interpersonal understanding was also correlated with age and social class. Nevertheless, interpersonal understanding and means-ends problem-solving ability made significant contributions in accounting for variance in several competence variables even after IQ and other important status variables were taken into account. Implications for social cognition research are discussed.     

Role strain,engagement and academic achievement in early adolescence

The present study was designed to investigate the relationships between role strains following the transition to secondary school and academic achievement. Academic engagement was hypothesized to mediate between role strain and achievement. The sample consisted of 749 students in their first year of secondary school. Four types of role strain were investigated: parent, teacher, school and peer. Parent and teacher role strains appeared to be negatively associated with academic achievement, as mediated through academic engagement. Parent and school role strain were directly and negatively associated with achievement. Results are discussed in the light of parenting practices and the developmental mismatch hypothesis.     

Sibling and peer victimization in childhood and adolescence

This study examined how victimizations by either a sibling or peer are linked to each other and to mental health in childhood and adolescence. The data were from the National Survey of Children's Exposure to Violence which includes a sample of children aged 3–9 (N = 1,536) and adolescents aged 10–17 (N = 1,523) gathered through telephone interviews. An adult caregiver (usually a parent) provided the information for children while self-reports were employed for adolescents. Fifteen percent of each age group reported victimization by both a sibling and peer. Victimization by a sibling alone was more common in childhood than adolescence. Victimization by a sibling was predictive of peer victimization. Children and adolescents victimized by both a sibling and peer reported the greatest mental distress. This work establishes that for some children and adolescents, victimization at the hands of other juveniles happens both at home and school. Programs should consider the role of siblings and target parents and siblings to encourage the development and maintenance of constructive sibling interactions.     

Continuity and discontinuity of attachment from infancy through adolescence

This study reports relations between infant Ainsworth Strange Situation classifications, negative life events, and Adolescent Attachment Interview classifications. Overall, the stability of secure versus insecure classifications was 77%, and infant attachment classification was a significant predictor of adolescent attachment classification. Chi-square analyses indicate that negative life events are significantly related to change in attachment classification. The sample (n = 30) is drawn from the Family Lifestyles Project (FLS), an ongoing longitudinal study of children's development within the context of nonconventional family lifestyles. The distribution of family lifestyles within this study, unlike those in the full FLS sample, represent a higher proportion of conventional two-parent families (40%). There were no differences between adolescents reared in conventional or nonconventional families in the distribution of adolescent attachment security, the experience of negative life events, or the continuity of attachment from infancy through adolescence.     

The relationship between math anxiety and math achievement in young children is mediated through working memory,not by number sense,and it is not direct

Math anxiety is considered a predictor of math achievement, although the cognitive mechanism whereby math anxiety impairs math achievement is unclear. The paper presents the results of cross-sectional (N = 241) and longitudinal (N = 369) studies conducted among early school-aged children on the cognitive mechanism whereby math anxiety impairs math achievement. The following hypotheses were tested: (1) math anxiety directly affects math achievement; (2) in accordance with processing efficiency and attentional cognitive theories, math anxiety indirectly affects math achievement through working memory; (3) in accordance with the cognitive deficit model, math anxiety indirectly affects math achievement through number sense. The results mostly confirm the mediating role of working memory and undermine the mediating role of number sense and the direct path in the relationship between math anxiety and math achievement. Because previous studies undertaken in adults show the direct path from math anxiety to math achievement and the role of symbolic number processing in explaining the relationship between the two, the methodological and developmental aspects of the obtained results are discussed in the paper.     

Learning disabilities and psychological development in childhood and adolescence

The relationship between learning disabilities and psychological development is a complex, ongoing intrapsychic and psychosocial process. The results of two clinical-psychological investigations about a group of learning-disabled children and a group of learning-disabled adolescents is summarized. Although the learning-disabled youngsters were psychologically more heterogeneous than homogeneous, several common configurations emerged that characterized these children and adolescents: (1) problems in work and learning (due to the learning disability itself and to psychogenic factors related directly and/or indirectly to the disability); (2) chronic, low-level depression and relatively high, free floating anxiety; (3) characteristic unconscious concerns about self and others. In addition, learning disabilities organize psychological development in determining strengths, weaknesses, interests, and defensive strategies. And, the intermittent nature of mild to moderately severe learning disabilities seems to contribute to a sense of being traumatized and to character riqidity. The educational and clinical implications are briefly discussed.     

Unwanted and illegal sexual experiences in childhood and adolescence

Three hundred forty-two anonymous surveys regarding unwanted sexual experiences (USE) were filled out in three clinic sites: a pediatric sexual abuse clinic, family practice clinic, and family planning clinic. In the latter two clinics, 40% of females and 16% of males had at least one unwanted sexual experience prior to turning 18 years old. Only 91% of the sexual abuse clinic patients indicated their experience was unwanted. In addition, 27% of the subjects had wanted sexual experiences that were illegal and underreported: These experiences involved a partner at least 4 years older or younger. While feelings of victimization were most common, self-blame and naivete about the abuse were also frequently reported, especially in those who had an USE with a peer. Ambivalence, self-blame, and peer pressure were associated with a lower tendency to disclose one's USE. Although unwanted and illegal sexual experiences were less common in Hispanic females, feelings of self-blame and ambivalence regarding their USE were more frequent in comparison with White females. These findings have important investigative and therapeutic implications for professionals who encounter victims of sexual abuse.     

The relative contributions of the Cattell‐Horn‐Carroll cognitive abilities in explaining writing achievement during childhood and adolescence

This study examined the relative contributions of measures of Cattell‐Horn‐Carroll (CHC) cognitive abilities in explaining writing achievement. Drawing from samples that covered the age range of 7 to 18 years, simultaneous multiple regression was used to regress scores from the Woodcock‐Johnson III (WJ III; Woodcock, McGrew, & Mather, 2001) that represent CHC broad and narrow abilities onto the WJ III Basic Writing Skills and Written Expression cluster scores. At most age levels, Comprehension‐Knowledge demonstrated moderate to strong effects on both writing clusters, Processing Speed demonstrated moderate effects on Basic Writing Skills and moderate to strong effects on Written Expression, and Short‐Term Memory demonstrated moderate effects. At the youngest age levels, Long‐Term Retrieval demonstrated moderate to strong effects on Basic Writing Skills and moderate effects on Written Expression. Auditory Processing, and Phonemic Awareness demonstrated moderate effects on only Written Expression at the youngest age levels and at some of the oldest age levels. Fluid Reasoning demonstrated moderate effects on both writing clusters only during some of the oldest age levels. Visual‐Spatial Thinking primarily demonstrated negligible effects. The results provide insights into the cognitive abilities most important for understanding the writing skills of children during the school‐age years. © 2008 Wiley Periodicals, Inc.     

Developmental trajectories of externalizing behaviors in childhood and adolescence

This article describes the average and group-based developmental trajectories of aggression, opposition, property violations, and status violations using parent reports of externalizing behaviors on a longitudinal multiple birth cohort study of 2,076 children aged 4 to 18 years. Trajectories were estimated from multilevel growth curve analyses and semiparametric mixture models. Overall, males showed higher levels of externalizing behavior than did females. Aggression, opposition, and property violations decreased on average, whereas status violations increased over time. Group-based trajectories followed the shape of the average curves at different levels and were similar for males and females. The trajectories found in this study provide a basis against which deviations from the expected developmental course can be identified and classified as deviant or nondeviant.     

Maltreatment experience in childhood and average excess body mass from adolescence to young adulthood

BackgroundPrior studies have suggested maltreatment is a strong predictor of later weight outcomes, such that maltreatment experiences in childhood increase the likelihood of being overweight or obese in adulthood. Estimates of this relationship may be biased due to: 1) inadequate selection of covariates; 2) improper operationalization of child maltreatment; and 3) restricting analyses to cross-sectional outcomes.ObjectivesEvaluate how latent classes of child maltreatment experiences are associated with a longitudinal BMI measure from adolescence to adulthood.ParticipantsData from the National Longitudinal Study of Adolescent to Adult Health.MethodsWe evaluated how previously developed latent classes of child maltreatment experiences were associated with average excess BMI from adolescence to adulthood using multivariate linear regression.ResultsIn the unadjusted model, individuals in the poly-maltreatment class (b = 0.46, s.e. = 0.20) and individuals who experienced adolescent-onset maltreatment (b = 0.36, s.e. = 0.11) had higher average excess BMI compared to individuals in the no maltreatment class. After adjusting for confounders, the relationship between poly-maltreatment and average excess BMI abated, whereas the relationship between adolescent-onset maltreatment and average excess BMI sustained (b = 0.28, s.e. = 0.11).ConclusionsContrary to previous findings, our analyses suggest the association between maltreatment experiences and longitudinal weight outcomes dissipates after controlling for relevant confounders. We did find a relationship, however, between adolescent-onset maltreatment and average excess BMI from adolescence to adulthood. This suggests the importance of maltreatment timing in the relationship between maltreatment and weight.
