Expert performance in a domain is often defined as maximal adaptation to stable task constraints. This definition is useful when analysing the vertical transition when novices become experts. However, many workplaces undergo considerable changes and, thus, task constraints change as well. In this paper a complementary conceptualisation of…

Visual search is faster when a fixed target location is paired with a spatially invariant (vs. randomly changing) distractor configuration, thus indicating that repeated contexts are learned, thereby guiding attention to the target (contextual cueing [CC]). Evidence for memory-guided attention has also been revealed with electrophysiological…

Early identification of Minimal Brain Dysfunction (MBD) is now easier, partly as a result of a series of 3 studies made in rural Vermont over a period of 15 years. MBD victims exhibit different behaviors at different ages. "Fidgetiness", a "nuisance" factor, and poor learning are all strong predictors of MBD for children at the…

The purpose of the present study was to examine the relations among resting frontal brain electrical activity (EEG) (hypothesized to reflect a predisposition to positive versus negative affect and ability to regulate emotions), emotional intelligence, and externalizing behaviors in a sample of non-clinical 10-year-old children. We found that boys…

This comprehensive look at retirement as a transitional life stage was instituted by the Federal Government in order to initiate theory building in this much neglected area. Conferences participated in by experts were held at intervals so as to maximize interactive thinking. Following this give and take, participants formulated theoretical models…

Relations between self-assessed health status and satisfaction with health care were examined using two waves of data obtained from participants in the Medical Outcomes Study. Using a multisample covariance modeling framework, separate models were examined for patients with significant symptoms of depression (N=417) and patients with chronic…
