A total of 61 children from first through sixth grades participated in four balance-scale and four inclined-plane problem types in a study testing for invariance of subject classifications as rule-users across problems whose products differed but whose type did not. Results indicated that many children's classifications differed across…

Examines 16 major community surveys designed to measure prevalence of childhood emotional and behavioral conditions, discussing definitions of deviance, instruments, and methodologies used, as well as potential correlates of disorders studied. Suggests directions for research. (Author/MP)

Contrary to the deterministic nature of the adipocyte- number hypothesis, correlations between adiposity data recorded during infancy and data recorded during the school- age period or later are very low. There is no convincing evidence the obese infant has more than a slight tendency to become an obese adult. (Author/MP)

In response to criticisms of a study conducted by Shaffran and Decarie, the author underscores the need for objective, accurate peer evaluation. Errors and misinterpretations in the critical article are reported and corrected. (Author/RH)

Replies to Solomon's paper that basic criticisms made earlier of Shaffran and Decaries' study still apply. Views the study as essentially a confirmation of the null hypothesis based on weak measures. (Author/RH)

Examines and rejects common criticisms of the causality concept; shows causality is a relation implied in the grammar of a language about objects. Discusses objective criteria for concepts of causal relations and explains how the concept of causality may be modified to have causes determine probabilities of outcomes. (Author/RH)

This paper provides a critical examination of the current status of metamemory. First, review of background influences and a critique of conceptualizations of metamemory are presented. Next, research methods are examined, and empirical results concerning the relationship between metamemory and memory are reviewed. Finally, several suggestions are…

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…

Suggests that societal change occurs more rapidly than dependable developmental research findings emerge. The research establishment in developmental psychology is examined to determine aspects which affect the ability of the system to produce better results faster. (BRT)

Provides a set of guidelines for evaluating research using structural equation modeling (SEM). Offers insight into how someone familiar with SEM would judge the adequacy of a study using such methods. (Author/RH)

Demonstrates ways in which conclusions about models may be affected by violations of the assumption that the observed variables are normally distributed. Addresses the issue of the robustness of findings obtained under such conditions. (Author/RH)

Analyzes methods used to record infant head position and the limits of these methods. An experimental device is proposed which records infant head turning and head righting when the vestibular system is stimulated. (Author/DB)

This study investigated the common practice in infant research of eliminating from reported data large numbers of subjects who prove uncooperative (sleepy, fatigued, fussy) during the experiment. It was suggested that these excluded infants constitute a special class of subjects and that the inclusion of their data would greatly alter the research…

Discusses principles of human development which are durable across changes in time, culture, and cohort. Analyzes the form these principles are likely to take, the limitations and strengths they are likely to display, and the process by which they are likely to be discovered. (Author/JMB)
