This study assesses the consequences of housing instability during the first 5 years of a child's life for a host of school readiness outcomes. Using data from the Fragile Families and Child Wellbeing Study (n = 2,810), this study examines the relation between multiple moves and children's language and literacy and behavior problems at…

Explaining inconsistency may serve as an important mechanism for driving the process of causal learning. But how might this process generate amended beliefs? One way that explaining inconsistency may promote discovery is by guiding exploratory, hypothesis-testing behavior. In order to investigate this, a study with young children ranging in age…

Beginning in sixth grade at an average age of 11.9 years, 416 adolescents and their parents participated in 4 waves of data collection involving family observations and multiple-reporter assessments. Ecological theory and the process-person-context-time (PPCT) model guided the hypotheses and analyses. Lagged, growth curve models revealed that…

Bronfenbrenner's (1979) ecological model proposes that events in higher order social ecosystems should influence human development through their impact on events in lower order social ecosystems. This proposition was tested with respect to ecological violence and the development of children's aggression via analyses of 3 waves of data (1 wave…

A crucial skill in scientific and everyday reasoning is the ability to interpret data. The present study examined how data features influence data interpretation. In Experiment 1, one hundred and thirty-three 9-year-olds, 12-year-olds, and college students (mean age = 20 years) were shown a series of data sets that varied in the number of…

Tattling, defined as the reporting to a second party of norm violations committed by a third party, is a frequent but little-studied activity among young children. Participant observation and quantitative sampling are used to provide a detailed characterization of tattling in 2 preschools (initial mean age = 4.08 years, N = 40). In these…

Epstein (1974) claims evidence for regular two-year growth spurts in the development of brain and mind, a phenomenon he calls phrenoblysis. Unfortunately, repeated analysis of the data he presents as proof of his theory provides no support. (Author/RH)

In cross-cultural child development research there is often a need to translate instruments and instructions to languages other than English. Typically, the translation process focuses on ensuring linguistic equivalence. However, establishment of linguistic equivalence through translation techniques is often not sufficient to guard against…

This study of the stability of parent behaviors toward toddlers over a 3-week period used both aggregated and nonaggregated data. Comparison of stability correlations indicated higher stabilities for aggregated scores, with the level of stability increasing as scores from additional single sessions were aggregated. (PCB)

Written in response to an article (Horn, 1983) that appeared in special Developmental Behavioral Genetics section of CHILD DEVELOPMENT (Volume 54), this commentary (1) notes some issues concerning Horn's analysis and interpretation of data and (2) highlights the potential for interpretational bias in behavior genetics research. (Author/BE)

In this rebuttal to Walker and Emory's commentary (also in this issue), Horn argues that the issue of the influence of environment on the average IQ of adopted children was well discussed in his article (Volume 54 of CHILD DEVELOPMENT). (BE)

Demonstrated that time sampling is inaccurate for estimating durations or frequencies of behaviors. Also concluded that (1) individual or group differences can change depending on whether time sampling or continuous sampling is used; and (2) error rates are high when bout lengths of behaviors are short or when interval length is long. (BC)

A data analysis procedure for testing the hypothesis that one task is a developmental prerequisite for another task is illustrated. The procedure was applied to new data on the acquisition of conservation concepts to test the hypothesis that synthesis, visual-scanning skills, and memory capacity are prerequisites of conservation mastery.

Discusses building blocks for a developmental psychopathology, focusing on studies of risk, competence, and protective factors. Describes studies of stress and competence, giving particular attention to methodology and strategies for data analysis. A three-model approach to stress resistance is also presented, and Project Competence is evaluated…

Conducted meta-analysis of preschool and early elementary school self-esteem instruments, using reliability as criterion variable and different aspects of methodology used in testing an instrument as predictor variables. Found that reliability could be predicted by study setting, number of items in the scale, age of children being studied, method…
