The objectives of this study are to analyze the effect of a short nap on the level of alertness and on the drivers’ ability to detect the motorcyclists on the road according to the size of his/her useful visual field (UVF).Nineteen participants (m = 21 years old) carried out a driving task with a simulator, after taking a short nap (30 min) in the vehicle or not. They had to distinguish the colour change of a signal on a vehicle they were following and to detect a motorcycle which briefly appeared on the road at different eccentricities.Drivers with a limited UVF are those who detect the fewest motorcycles. Taking a short nap before the driving does not have any significant effect on data related to vision (motorcycles and signals detected), driving and alertness state ((α+θ)/β). There is a linear relationship between the size of the UVF and the ability to detect the motorcycle appearing in the left outside mirror.The implications of the results concerning the short nap as a countermeasure to a decrease in alertness and the perception of motorcycles according to extent of the useful visual field of the driver are discussed in terms of road safety. 相似文献
We argue that causal decision theory (CDT) is no worse off than evidential decision theory (EDT) in handling entanglement, regardless of one’s preferred interpretation of quantum mechanics. In recent works, Ahmed (Evidence, decision, and causality, Cambridge University Press, Cambridge, 2014) and Ahmed and Caulton (Synthese, 191(18): 4315–4352, 2014) have claimed the opposite; we argue that they are mistaken. Bell-type experiments are not instances of Newcomb problems, so CDT and EDT do not diverge in their recommendations. We highlight the fact that a Causal Decision Theorist should take all lawlike correlations into account, including potentially acausal entanglement correlations. This paper also provides a brief introduction to CDT with a motivating “small” Newcomb problem. The main point of our argument is that quantum theory does not provide grounds for favouring EDT over CDT.
Abstract. When understood as a potential resolution for the epistemological impasse between psychology and religion, Hebrew wisdom presents a model for dialogue. Noting that wisdom exhibits a special interest in human dispositions and behavior, the authors compare Viktor Frankl's logotherapy and Adlerian psychology with Proverbs and uncover a biblical, empirical approach to psychology which indirectly incorporates the religious dimension. 相似文献
Subjects wore goggles with prisms that laterally displaced the visual field (rightward by 11.4 degree) and with full view of the limb engaged in paced (2-s rate) sagittal pointing at either an implicit ("straight ahead of the nose") target (Experiment 1) or an explicit (positioned leftward by 11.4 degree) target (in Experiment 2). In experimental conditions, subjects performed a secondary cognitive task (mental arithmetic) simultaneously during target pointing. In control conditions, no cognitive load was imposed. Aftereffect measures of adaptation to the prismatic displacement were not substantially different when problem solving was required, but terminal error of the exposure pointing task was reliably affected by cognitive load. These results are consistent with the hypothesis of separable mechanisms for adaptive coordination and adaptive alignment. Adaptive coordination may be mediated by strategically flexible coordinative linkage between sensory motor systems (eye-head and hand-head), but spatial alignment seems to be mediated by adaptive encoders within coordinatively linked subsystems. If the coordination task involves predominately automatic processing, coordinative linkage can be frequent enough under cognitive load for substantial realignment to occur even though exposure performance (adaptive coordination) may be less than optimal. 相似文献
Edward Tiryakian, Thomas Robbins and Phillip Hammond, among others, have highlighted the role of new religious movements (NRMs) as reflectors of larger social trends and innovators of broad cultural change. This paper presents a case study of the Eleventh Commandment Fellowship, a subgroup of the Holy Order of MANS (an American NRM founded in 1968) that attempted to uncover and articulate an ethic of ecology from within the Judeo‐Christian tradition during the late 1970s and 1980s. I contend that these efforts both reflected the broader movement within North American Christian denominations to engage seriously the ecological crisis, and offered innovative theoretical and practical solutions to this crisis. The fellowship is also shown to have been instrumental in the formation of an international coalition of both religious and secular environmental groups. 相似文献
The present study consisted of developing the Kuder Task Self-Efficacy Scale (KTSES). The KTSES is a 30-item scale measuring a person's self-efficacy for tasks corresponding to Kuder's 10 occupational interest areas (Kuder Zytowski, 1991). Responses from the KTSES were compared with responses to the Self-Esteem Inventory (SES; Rosenberg, 1965) and the Career Decision-Making Self-Efficacy Scale (CDMSE; Taylor Betz, 1983) to see if career task self-efficacy was related to self-esteem and career decision-making self-efficacy. Answers to the KTSES were also compared with responses given for occupations corresponding to the Kuder Occupational Interest Survey (KOIS; Kuder Zytowski, 1991) to see if occupational self-efficacy was related to career task self-efficacy. Results supported the validity and reliability of the KTSES. The utility of having a task self-efficacy scale to go with the KOIS is discussed, and ideas for future research are given. 相似文献
A series of studies examined the (Sprague-Dawley) rat's tendency to suppress intake of .15% saccharin when it was followed by a second food after 4-, 16-, or 32-min delays. The second foods examined were 32% sucrose, 64% sucrose, lab chow, a Nutrasweet solution, skim milk, and chocolate milk. Saccharin intake was influenced by both the delay and the specific food available. Subsequent analysis showed that saccharin intake before the 4-min delay was an inverse function of the caloric value of the second food. However, saccharin intake before the 16-min delay was better predicted as an inverse function of the hedonic value of the second food. The results suggest that the caloric and hedonic values of a food may influence food selection across different time courses, and that the effective time horizon for the sequential comparison of foods depends on the specific foods that are compared. 相似文献
