Misperception of speed under low-contrast conditions has been identified as a possible contributor to motor vehicle crashes in fog. To test this hypothesis, we investigated the effects of reduced contrast on drivers' perception and control of speed while driving under real-world conditions. Fourteen participants drove around a 2.85 km closed road course under three visual conditions: clear view and with two levels of reduced contrast created by diffusing filters on the windscreen and side windows. Three dependent measures were obtained, without view of the speedometer, on separate laps around the road course: verbal estimates of speed; adjustment of speed to instructed levels (25 to 70 km h(-1)); and estimation of minimum stopping distance. The results showed that drivers traveled more slowly under low-contrast conditions. Reduced contrast had little or no effect on either verbal judgments of speed or estimates of minimum stopping distance. Speed adjustments were significantly slower under low-contrast than clear conditions, indicating that, contrary to studies of object motion, drivers perceived themselves to be traveling faster under conditions of reduced contrast. Under real-world driving conditions, drivers' ability to perceive and control their speed was not adversely affected by large variations in the contrast of their surroundings. These findings suggest that perceptions of self-motion and object motion involve neural processes that are differentially affected by variations in stimulus contrast as encountered in fog. 相似文献

Numerous studies of either sex role behavior (masculinity/femininity) or women's role attitudes (contemporary/traditional) as related to menstrual distress have amassed inconsistent and contradictory results. It was proposed that these two role variables may hold an interactive relationship with menstrual distress, and their study in isolation may have provoked less reliable results. An interaction was found with masculine women preferring a contemporary role and feminine women committed to traditional role values reporting greater menstrual and premenstrual distress. Feminine Contemporary and masculine traditional women revealed less distress ássociated with the menstrual cycle. 相似文献

Moralism is often described as a vice. But what exactly is wrong with moralism that makes it aptly described as a character flaw? This paper will argue that the problem with moralism is that it downgrades the force of legitimate moral criticism. First, I will argue that moralism involves an inflated sense of the extent to which moral criticism is appropriate. Next, I will examine the value of legitimate moral criticism, arguing that its value stems from enabling us to take a stand against immoral behavior. Finally, I will argue that unwarranted moral criticism downgrades the force of legitimate moral criticism and that this is why moralism should be seen as a vice. 相似文献

Professions have a social obligation to ensure that their members’ professional behavior is morally appropriate. The psychology profession in most jurisdictions delegates the responsibility of ensuring that psychologists entering the profession are ethically competent to pre-practicum training programs. Educators responsible for teaching the ethics courses in these programs often base them on Rest’s (1984, 1994) theory that does not take into account a vast amount of contemporary psychological and neuroscientific research data on moral decision making. My aim with this article is therefore to summarize the psychological and neuroscience research findings relevant to moral decision making and consider how educators who teach ethics courses can apply them in developing ethics courses grounded in research. 相似文献

This exploratory study examined gender roles and decision making among isiXhosa-speaking adolescents. Participants were a non-probability sample of 40 Grade 12 learners (females = 50%; aged between 17 and 24 years). Data were collected using identity status interviews and analysed thematically to profile the adolescents’ gender role identity statuses and related decisions. The findings suggest the adolescents to endorse gender roles somewhat discrepant to traditionalist roles in that females endorsed primary family financing provider and decision making, whereas the males were accepting of nurturing or carer roles in the family home. Gender role statuses and decision making among teenage isiXhosa appear to be shifting away from traditional roles towards modern thinking of gender equality. 相似文献

Abstract. Although we do not know whether intelligent extraterrestrials exist, they are a permanent fixture of literature and philosophical argument. Part of their appeal is that they watch us from above and thus serve as a metaphor for human self‐reflexivity. This makes fictional aliens especially useful when moral issues are at stake. In order to evaluate stories about aliens with respect to moral conclusions two conditions must be fulfilled. First, the stories have to be detailed enough that we can understand the circumstances of the aliens' moral choices. Therefore science fiction often is more useful than arguments involving aliens in short technical papers. Second, their fictional lives need to be possible in our own universe, or very nearly so, in order to be relevant for our own moral conduct. Taking as an example the unfallen aliens in C. S. Lewis's novels Out of the Silent Planet (1938) and Perelandra (1943), we can acknowledge the theological interest and literary subtlety. Nonetheless, the stories fail as moral parables in one important respect: The aliens depicted could not be a product of evolution in our universe, at least as we currently understand its scientific laws. This realization has important consequences for our self‐understanding and thus underlines how fictional aliens can be useful in making sense of the complexities involved in moral argumentation. 相似文献
