Whether IQ level exerts a differential effect on the impairment of cognitive performance induced during acute hypoglycemia was studied for 24 nondiabetic adults. At various levels of hypoglycemia, no overall effect of IQ on deterioration was noted. Higher IQ did not apparently protect against adverse effects. (SLD)

Noting that previous research showed younger siblings systematically more sexually active at given age than older siblings, used national data to explore relationship between sibling birth order and sexual behavior. Testing of process-oriented models revealed very slight support for opportunity model for white older sisters and white younger…

Developmental contextualism focuses on changes in fused relations between developing people and their changing contexts. Research on cognitive training in the aged years provides evidence about plasticity throughout life because it alters developmental trajectories through revised person-context relations. The studies in the current issue support…

Compared Child Behavior Checklist scores of 59 chemically dependent male adolescents with scores of normative group on 4 adaptive behavior scales and 12 behavior problem scales. Groups differed significantly on all measures. Compared to general clinical group, chemically dependent group scored significantly higher on delinquent and uncommunicative…

Reviews theories of women's identity that emphasize relational capacities. Briefly summarizes five theories and focuses on how these perspectives can be integrated and enrich counseling practices. Cautions against oversimplifying nature of women's identity and suggests that inclusive view of women's or men's identity must devote attention to…

A rule-plus-exception model (RULEX) of classification learning is proposed. According to RULEX, people learn to classify objects by forming simple logical rules and remembering occasional exceptions to these rules. Because the learning process is stochastic, people will vary in the rules formed and exceptions stored. (SLD)

Concluding article to special journal issue devoted to social and cultural diversity among adults aged 85 years old and older highlights major contributions made by articles in this issue. Discusses implications of articles for issues of methodological nature. Concludes that articles examined differentiating effects of social structural…

Reacts to Jennings and Skovholt's (1999) study on master therapists. Discusses the lack of clear definition of master therapist, lack of meaningful comparison groups needed to infer the distinctive characteristics of master therapists, the incomplete communication of data-analytic procedures, and the formulation of results as a uniform…

Compares eight models for analyzing count data through simulation in the context of prediction of absenteeism to indicate the extent to which each model produces false positives. Results suggest that ordinary least-squares regression does not produce more false positives than expected by chance. The Tobit and Poisson models do yield too many false…

Information about temperament differences among children may not be fully incorporated into the practice of school psychology. An increase in the diagnosis of attention deficit hyperactivity disorder may be related to insufficient appreciation of normal temperament variations. Research on children's temperament and consideration of…

Explores factors that influence the usefulness of individualized temperament materials for parents of infants. Most parents found the materials useful. Global perception of temperamental difficultness and educational level were associated with usefulness; usefulness was not associated with parity. Results suggest that temperament guidance…

This paper introduces dynamic latent-class models for the analysis and interpretation of stability and change in recurrent choice data. These latent-class models provide a nonparametric representation of individual taste differences. The approach is illustrated with an analysis of a purchase incidence data set. (SLD)

Studied developmental trends in social aspects of self-knowledge for 461 adolescent girls and boys. Results suggest that Individuality and Belonging are separate constructs, with considerable variability among adolescents. Discusses implications for the study of individual differences and age-related variations in the personal and social basis of…

Examined relation between individual differences in inhibitory control (IC) and theory-of-mind (ToM) performance in preschoolers. Found that IC was strongly related to ToM, even after controlling for several important factors. Inhibitory tasks requiring a novel response in face of a conflicting prepotent response and those requiring delay of a…

Imitation is an important means by which infants learn new behaviours. When infants do not have the opportunity to immediately reproduce observed actions, they may form a memory representation of the event which can guide their behaviour when a similar situation is encountered again. Imitation procedures can, therefore, provide insight into infant…
