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)

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…

The study attemped to link cognitive and social problems seen in girls with Turner syndrome by assessing the girls' ability to process affective cues. Seventeen 9- to 17-year-old girls diagnosed with Turner syndrome were compared to a matched control group on a task which required interpretation of affective intention from facial expression.…

This rejoinder to McCall (Volume 56, 217-218) discusses the differences in viewpoint with respect to the relationship between models and theory, the notion of "direct" tests of propositions, and the use of measures of explained variance to evaluate model performance. (Author/BE)

This introduction to a special section on psychobiological studies of stress and coping discusses the problems of interpreting and integrating information on stress reactivity derived from a combination of behavioral and physiological measures. (PCB)

Investigates the evidence that the imperfect performance in forward search of 36 children aged four and five years resulted from unstable execution of the correct component processes. Evidence suggests that five-year-olds engaged in forward search, but four-year-olds used only a rudimentary form of forward search. (RJC)

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)

Examined the ability of 2 1/2- to 4 1/2-year-olds to recognize and implement strategies for resolving comprehension difficulties. In contrast to previous experimental findings, results indicate that young children are capable of detecting a variety of comprehension problems and possess appropriate strategies for resolving these difficulties with a…

A total of 114 infants at three age levels (11, 18, and 28 weeks) were rated by their mothers on a termperament questionnaire and subjected to a habituation procedure. Results suggest that subject loss in habituation studies may be the result of nonrandom individual difference factors and not just the result of temporary fluctuations in state.…

Investigated the effects of caregiving experience on adults' thinking about a child-rearing problem. Study 1 found that, of 192 adults, parents were better than nonparents at diagnosing the cause of a baby's crying. Study 2 extended the first study's findings to 42 mothers and 42 nonmothers. (SKC)

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)

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)

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)

Study examined peer sensitivity to (1) differences in the social behaviors of hyperactive and normal comparison peers, and (2) medication-related behavioral differences. Discussion focused on children's detection of treatment-related differences in social behaviors of peers, as well as on the imperfect relation between social behavior and social…

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)
