The present series of studies sought to provide evidence that M would increase under any conditions which make an S more aware of his muscles. The studies demonstrated that at least in women, M increased over a variety of conditions involving heightened muscle awareness. Specifically M increased in conditions utilizing muscle activation, deactivation, hypnosis, and focusing thoughts on the body musculature. The muscle awareness model unlike the sensory-tonic model accounts for increases in M following hyperactivity as well as inhibition.  相似文献

A recent report by the National Research Council (Huey & Wickens, 1993) has identified transitions in task demand as an important dimension for study in vigilance research. This experiment tested the possibility that the effects of such transitions follow a relatively simple psychophysical rule—they are characterized by contrast effects. Transitions in task demand were achieved by shifting subjects from single-task to dual-task monitoring and vice versa. These transitions produced changes in subjects' sensing and decision-making functions that were far more intricate than simple contrast effects. The demand transition issue offers a complex research challenge on both basic and applied levels and warrants further investigation.  相似文献

The usage, derivation, and psychological, ethical, and legal aspects of slang terminology in medicine are discussed. The colloquial vocabulary is further described and a comprehensive glossary of common UK terms provided in appendix. This forms the first list of slang terms currently in use throughout the British medical establishment.  相似文献

This article develops the cognitive—emotional forager (CEF) model, a novel application of a neural network to dynamical processes in foraging behavior. The CEF is based on a neural network known as the gated dipole, introduced by Grossberg, which is capable of representing short-term affective reactions in a manner similar to Solomon and Corbit’s (1974) opponent process theory. The model incorporates a trade-off between approach toward food and avoidance of predation under varying levels of motivation induced by hunger. The results of simulations in a simple patch selection paradigm, using a lifetime fitness criterion for comparison, indicate that the CEF model is capable of nearly optimal foraging and outperforms a run-of-luck rule-of-thumb model. Models such as the one presented here can illuminate the underlying cognitive and motivational components of animal decision making.  相似文献

Abstract. Modern science has given us a revolutionary new understanding of the close interrelationship and interdependence of humans not only with all other humans but with all other living species and with the nonliving elements of the geosphere and the rest of the universe. This new understanding can provide a basis for new understandings of (1) the basic nature of religion, (2) the basic principles of major world religious traditions, and (3) the basic principles of religious ethics. The new understanding of religious ethics will involve a better understanding of our rights and responsibilities, as individuals and groups, with respect to other individuals and groups of humans, other living species, and the nonliving universe. This improved understanding will benefit not only human individuals and human societies, local and global, but also local and global ecosystems.  相似文献

Using a stratified sample of Canadian adolescents residing in Ontario (n = 2,154) time use patterns and perceptions of time pressure are explored to determine gender differences among younger (12–14 years) and older adolescents (15–19 years). For both age groups, girls report a higher total workload of schoolwork, domestic activities and paid employment and spend more time on personal care while boys have more free time, especially during early adolescence. Feelings of time pressure for teens increase with age and are significantly higher for girls in both age categories. Gender differences are less pronounced on school days when time is fairly structured, but become more consistent with traditional gender schema on the weekend when time use is more discretionary.  相似文献
