Our target article (Robinson-Cimpian, Lubienski, Ganley, & Copur-Gencturk, 2014) used nationally representative data to examine the development of gender gaps in math achievement. We found that when boys and girls demonstrate equivalent math test performance and are perceived by their teachers to be equally well behaved and engaged with the…

Developmental science rests on describing, explaining, and optimizing intraindividual changes and, hence, empirically requires longitudinal research. Problems of missing data arise in most longitudinal studies, thus creating challenges for interpreting the substance and structure of intraindividual change. Using a sample of reports of longitudinal…

Argues that more attention should be given to the specification of the independent and dependent variables which describe, explain and predict intraindividual stability and change over time. Statistical techniques for such study are briefly discussed. (Author/SDH)

Responds to Fogel's (1988) concerns about the validity and preferred uses of scaled monadic phases and introduces a note of caution about prematurely concluding that stochastic organization alone is of significance to development. (RH)

The extremely popular "training" studies, virtually all of which have been devoted to the attempt to experimentally induce conservation in nonconserving subjects, were discussed with respect to the logic underlying the method and surrounding theoretical and methodological difficulties. (Author/SDH)

Examines issues related to the design and interpretation of high-risk depression research, including the identification of symptoms and syndromes, categorical versus dimensional scales, aspects of depression to be considered, specificity of effects, use of process measures, and conceptualization of risk and resilience. (MDM)

Discusses procedures and considerations involved with secondary analyses of longitudinal databases. Procedures involve (1) formulating questions; (2) creating a feasibility matrix; (3) reformulating questions; (4) creating derived variables; (5) performing data reduction; (6) analyzing data; and (7) interpreting results. Problems associated with…

This commentary proposes that cross-cultural studies of parenting, like studies within a culture, should become more focused--with antecedent or concurrent measures selected to provide a clear view toward "child outcome." Furthermore, differences within countries may be as great as differences between countries. Therefore, the relevant cultural…

Suggests that testing developmental ordering hypotheses is difficult because rare use of ratio scales prevents direct comparison of measures. Demonstrates that the observed data pattern is constrained by the underlying relationship--although observed data pattern may not reflect the exact relationship, it limits possible relationships. Shows the…

Considers assumptions underlying design of Bussell et al.'s Nonshared Environment in Adolescent Development study. Suggests that a source of the common environment specific to this study is the effect of an individual in mutual ratings of relationship with siblings, leading to a larger common-environment effect across variables than within…

Addresses concerns raised in Neale's commentary regarding the Bussell et al. (1999) Nonshared Environment in Adolescent Development study. Discussion of assumptions focuses on those most relevant to study sample. Because Neale's proposed alternative models did not provide a better fit, the appropriateness of Bussell's model and importance of…

Examines methodological and conceptual issues related to the study of the effects of parental depression on children, focusing on the need to develop measures of relational behavior that are well-validated in high risk samples; relational assessments focused around central motivating systems; and methods that describe a variety of individual…

Comments on problems raised in this special issue, focusing on the distinctive aspects of the risk research reported. Highlights issues like sample characteristics, measurement strategies, specificity of risk factors, and risk mechanisms. Discusses the challenges of integrating alternative models of risk, with special references to research into…

Comments on research problems raised in this special issue. Suggests that recent research highlights the nature of the multiple processes underlying variability in child and adolescent adjustment. Views variability as a function of covarying influences from multiple domains, operating on specific developmental outcomes across a background of time…

Comments on the special theme issue examining the roles of socialization, biology, and culture as they affect adaptive and maladaptive developmental outcomes. Proposes a theory-guided research approach, based on four assumptive components of contemporary developmental theories: systematic change and relative plasticity; relationism and…
