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)

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)

The developmental significance of unresponsive or uncooperative behavior of children in standardized developmental assessments made during the preschool years was investigated. Untestable children were significantly lower than testable children on a wide range of abilities at all ages from 12 through 72 months. (PCB)

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)

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…

Discusses implications of a study of middle-class infants seen in the Ainsworth strange situation at 12.5 and 19.5 months; the investigation produced results inconsistent with the corpus of previous findings. (Author/RH)

Reports on a study designed (1) to modify one of the few existing standardized tests of conservation so that it can be used to assess the conservation of identity as well as the conservation of equivalence and (2) to use both versions of the test to gather additional evidence on the question of developmental priority among young children. (MP)

Focuses on systems theory as the paradigm underlying family therapy and considers the implications of this framework for conceptions of the individual, the study of parent-child interaction, and new research formulations and areas of study. Considers trends in the developmental field that move toward such formulations. (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)

Argues that, although Piaget's seminal work on children's use of intention and consequence information to make moral evaluations has spawned a substantial amount of research, progress in this area has been hampered by serious conceptual and methodological problems. Offers some methodological guidelines for conducting research in this area.…

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)
