Identifying change at the individual level is an important goal for researchers, educators, and clinicians. We present a set of statistical procedures for identifying individuals who depart from a normative change. Using Latent Change Scores models (LCS), we illustrate how the Individual Likelihood computed from a statistical model for change…

This study examines associations between leisure reading and reading skills in data of 2,525 students followed from age 7 to 16. As a step further from traditional cross-lagged analysis, a random intercept cross-lagged panel model was used to identify within-person associations of leisure reading (books, magazines, newspapers, and digital…

Children with higher working memory or updating (WMU) capacity perform better in math. What is less clear is whether and how this relation varies with grade. Children (N = 673, kindergarten to Grade 9) participated in a 4-year cross-sequential study. Data from 3 WMU (Listening Recall, Mr. X, and an updating task) and a standardized math task…

Interest in 21st century skills has brought concomitant interest in ways to teach and measure them. Games hold promise in these areas, but much of their potential has yet to be proven, and there are few examples of how to use the rich data from games to make inferences about players' knowledge, skills, and attributes. This article builds an…

Researchers have used various theories to explain deaf individuals' reading skills, including the dual route reading theory, the orthographic depth theory, and the early language access theory. This study tested 4 groups of children--hearing with dyslexia, hearing without dyslexia, deaf early signers, and deaf late signers (N = 857)--from 4…

During the transition to adolescence, several developmental trends converge to increase the importance of peer relationships, the likelihood of peer-related stressors, and the experience of depressive symptoms. Simultaneously, there are significant changes in parent-child relationships. The current study sought to evaluate whether positive…

Solving simple arithmetic word problems is a major ability that children must acquire throughout the primary-grade mathematics curriculum. However, this skill is often challenging for them. For instance, "unknown referent problems" are more difficult to solve than "unknown compare problems." In unknown compare problems, the…

In an examination guided by cognitive developmental and attribution theory of how explanations of wealth and poverty and perceptions of rich and poor people change with age and are interrelated, 6-, 10-, and 14-year-olds (N = 88) were asked for their causal attributions and trait judgments concerning a rich man and a poor man. First graders, like…

Experimental approaches can help disentangle the impacts of policies from the effects of individual characteristics, but the heterogeneity of implementation inherent in studies with complex program designs may mask average treatment impacts (Morris & Hendra, 2009). In the case of the Opportunity NYC-Family Rewards (ONYC-Family Rewards),…

This study explores the trajectory of suicidal ideation in childhood and adolescence and identifies its strong predictors. Secondary data obtained from two nationally representative cohorts of South Korean youth were longitudinally analyzed using frequencies, percentages, and discrete time survival analysis. This study revealed an increase in the…

The last several decades have witnessed a large increase in the number of girls who participate in sports in the United States. Today an estimated 8 million third- through 12th-grade girls and 12 million boys participate in organized and team sports. While much progress has been made toward achieving gender equity in youth sports, too many girls…

The time-based resource-sharing model (P. Barrouillet, S. Bernardin, & V. Camos, 2004) assumes that during complex working memory span tasks, attention is frequently and surreptitiously switched from processing to reactivate decaying memory traces before their complete loss. Three experiments involving children from 5 to 14 years of age…

Study aim: To examine the prevalence of obesity and its correlation with blood pressure, waist circumference and other health related risk factors (smoking, alcohol consumption, physical inactivity and TV/PC-screen time) in German youths. Material and methods: A cohort of 831 boys and 808 girls, fifth- to tenth-graders from 3 German high schools…

Purpose: Literacy plays an important role in the development of language in school-age children and adolescents. For example, by reading a variety of books, magazines, and newspapers, students gain exposure to complex vocabulary, and reading becomes a prime opportunity for learning new words. Despite the importance of reading for lexical …

In this study, 434 children and adolescents completed the Control-, Agency-, and Means-ends beliefs Interview (CAMI). Moreover, we asked for current mood-state and achievement-related affect after success and failure at school. There was no gender difference in achievement-related affective expression in children (9 and 10 years old), but there…
