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…

This research examined the influence of delay and anticipated health and enjoyment on the amount of retirement savings sacrificed for early retirement. In addition to testing and supporting predictions that willingness to sacrifice retirement savings would be less with shorter delays to retirement, greater anticipated health, and greater…

Howard Garner's book Multiple Intelligences was important in psychology because it sought to relate a neuropsychological theory of common mental processes with a view of individual differences implicit in the term intelligences. New developments in imaging and genetics may make these connections more realistic.

Dual-process theories of the mind are ubiquitous in psychology. A central principle of these theories is that behavior is determined by the interplay of automatic and controlled processing. In this article, the authors examine individual differences in the capacity to control attention as a major contributor to differences in working memory…

This study examined the moderating role of the individual differences of goal orientation and affectivity on self-efficacy development. Consistent with hypotheses, results indicate that both positive and negative affectivity moderate the impact of an enactive mastery training program on efficacy development, with those higher in positive…

Stress can enhance or impair memory performance. Both cortisol release and sympathetic nervous system responses have been implicated in these differential effects. Here we investigated how memory retrieval might be affected by stress-induced cortisol release, independently of sympathetic nervous system stress responses. Thirty-two healthy…

This article presents a rejoinder to Rogosa's (2004) commentary on the author's (Molenaar, 2004) focus article titled, "A Manifesto on Psychology as Idiographic Science." The expert commentary of Rogosa brings up some central issues that require careful evaluation. The basic message of the author's focus article was straightforward: In general,…
