Parents and non-parental adults who interact with children influence child development. This study evaluates the knowledge of child development in two large and diverse samples of adults from Alberta in 2007 and 2013. Telephone interviews were completed by two random samples (1,443 in 2007; 1,451 in 2013). Participants were asked when specific…

Current knowledge about face processing in infancy comes largely from studies using static face stimuli, but faces that infants see in the real world are mostly moving ones. To bridge this gap, 3-, 6-, and 9-month-old Asian infants (N = 118) were familiarized with either moving or static Asian female faces, and then their face recognition was…

Two approaches to conceptualizing ethnic-racial identity development dominate the literature within developmental psychology--1 focused on the process of ethnic-racial identity development, including exploration and commitment, and another focused on the evaluative components of identity, including private and public regard. In this study, we…

One way to avert negative influences on well-being when confronted with blocked goals is the flexible adjustment of one's goals to the given situation. This study examines developmental differences in flexible goal adjustment (FGA) regarding age and gender in a sample of N = 815 participants (10 to 20 years; M = 13.63, SD = 2.60, 48.5% male).…

This study examines whether disagreeable youth are distinct from aggressive youth, victimized youth, and withdrawn youth. Young adolescents (120 girls and 104 boys, M = 13.59 years old) completed personality and adjustment inventories. Aggression, withdrawal, and victimization scores were derived from peer nominations (N = 807). Cluster analyses…

Reviews methods for testing whether two or more correlation matrices differ from each other. Illustrates methods for evaluating the similarities of two independent correlation matrices, such as those obtained from boys and girls, and two dependent correlation matrices, such as those obtained in longitudinal research that uses multiple measures.…

The concepts of quantitative and structural change are considered from a multivariate perspective. A hybrid of these two types of change, quantistructural change, is described. (CS)

The Home Observation for Measurement of the Environment (HOME) underwent a generalizability study examining the consistency and stability of scores. Canonical correlation and principal components factor analysis indicated that the organization of environment changes over the first two years of life, and the amount--not type--of stimulation is…

Recognizes some of the limitations of the field of behavioral genetics, but argues that the methods employed in multivariate behavior genetics and developmental behavior genetics have become the dominant paradigms in the field. (MDM)

Criticizes the application of the statistical procedures of the population-genetic approach within evolutionary biology to the study of psychological development. Argues that the application of the statistical methods of population genetics--primarily the analysis of variance--to the causes of psychological development is bound to result in a…

Argues that a truly developmental behavior genetics will have to go beyond the traditional quantitative approach of population genetics in order to produce developmental explanatory content about differences and similarities in developmental outcomes. (MDM)

Fuzzy trace theory posits that during development the use of verbatim information for solving transitive relationships shifts to the use of gist information. In cognitive developmental research that uses a cross-sectional design, the binomial mixture model is often used to identify such shifts. Because the binomial mixture model assumes equal task…

Configural frequency analysis (CFA) is suggested as a technique for longitudinal research in developmental psychology. Stability and change in answers to multiple choice and yes-no item patterns obtained with repeated measurements are identified by CFA and illustrated by developmental analysis of an item from Gorham's Proverb Test. (Author/DWH)

Raymond B. Cattell's research has produced many conceptual, methodological, measurement, and data analysis tools for identifying and studying interindividual differences and similarities in intraindividual change patterns. Additional Cattell contributions to lifespan developmental research include personality and ability concepts and their…

Children's internalizing problems are a concerning mental health issue, due to significant prevalence and continuity over time. This study tested a multivariate model predicting young children's internalizing behaviors from parenting practices, parents' anxiety-depression and family stressors. A community sample of 2 year old children (N=112) was…
