Car driving related attentional demands fluctuate according to route complexity and are found to be highly associated with motor-vehicle collisions (MVCs). The purpose of the current study was to explore the inherent attentional demands of scenarios that approximate common crash configurations. Sixty drivers completed a series of 20 simulated driving scenarios incorporating either rear-end or crossing path situations. For each scenario, the complexity of the driving environment was systematically manipulated in terms of vehicle handling and information processing elements. The attentional demands of each scenario were assessed by means of a peripheral detection task (PDT) as well as through a subjective measure of overall difficulty. Our results showed a reduction in PDT performance at intersections where information processing is increased as well as when handling maneuvers behind a lead vehicle were required. The results point to the appropriateness of the PDT as a sensitive measure of cognitive workload. The implications of these findings for future research and safety initiatives are discussed. 相似文献

Motivational externalists and internalists of various sorts disagree about the circumstances under which it is conceptually
possible to have moral opinions but lack moral motivation. Typically, the evidence referred to are intuitions about whether
people in certain scenarios who lack moral motivation count as having moral opinions. People’s intuitions about such scenarios
diverge, however. I argue that the nature of this diversity is such that, for each of the internalist and externalist theses, there is a strong prima facie reason to reject it. That much might not be very
controversial. But I argue further, that it also gives us a strong prima facie reason to reject all of these theses. This is possible since there is an overlooked alternative option to accepting any of them: moral motivation pluralism, the view that different internalist and externalist theses correctly accounts for different people’s concepts of moral opinions, respectively. I
end the paper with a discussion of methodological issues relevant to the argument for moral motivation pluralism and of the
consequences of this view for theories about the nature of moral opinions, such as cognitivism and non-cognitivism. 相似文献

This paper focuses on how different types of motivations can condition satisfaction with life, studying whether individual
heterogeneity in motivations affects the relationship between income and life satisfaction and whether the relationship between
motivation and satisfaction differs for people in different income-groups. Data used in this study comes from the World Values
Survey and the focus is placed on the relationship between income, motivation and satisfaction with life. Once variables such
as gender, age, religion, health or education are controlled for, we find that different motivations significantly affect
individual wellbeing. Moreover, our results suggest that moving from extrinsic to intrinsic motivation leads individuals to
enjoy greater satisfaction with life. This is so independent of the level of income, but the role of intrinsic motivation
is particularly significant for people in the low-income class. Life satisfaction also increases, within extrinsic motivation,
when moving from importance placed on a good income to focusing on security and, within intrinsic motivation, when moving
from emphasis placed on social relatedness to an increased feeling of accomplishment. Overall, our results suggest that different
goals and intended outcomes condition individual’s perceptions of wellbeing, with intrinsic motivations being crucial in attaining
greater levels of satisfaction with life. 相似文献

We describe the development and evaluation of a computer-controlled system for delivering odors in a magnetic resonance imaging
(MRI) environment. The system allows a timely presentation of different odors in synchrony with MRI sequences and participant’s
inspiration phase. The rise/fall time of odor deliverance has been optimized to generate prompt and strong stimulations. Equipped
with a user-friendly programming interface, the system can be used reliably in a wide range of experimental paradigms. We
have paid particular attention to developing a portable system that is relatively easy, rapid, and inexpensive to replicate.
The equipment has been tested in a 3-Tesla MRI in a boxcar paradigm, in which stimulation conditions alternated with rest
periods (no stimulation). The experiment demonstrated the good functioning of the device and its efficiency in producing the
expected activation in the olfactory cortex; it also revealed some methodological and technical aspects to be improved. 相似文献

The study of touch has recently grown, due mainly to the extensive use of several types of actuators that stimulate several
subsystems of touch. There is a widespread interest in applying these mechanisms to the study of the neurophysiological correlates
of tactual perception. In this article, we present a new device (the tactile spinning wheel [TSW]) for delivering textured
surfaces to the finger pad. The TSW allows one to control several parameters of the stimulation (angular speed, texture, etc.)
and, connected to an EEG recording system, makes it possible to study neural electrophysiological events. The device consists
of a rotating platform on which the tactile stimuli are fixed, a system that synchronizes stimuli onset with the EEG system,
and an electronic interface that controls the platform. We present the technical details of the TSW, its calibration, and
some experimental results we have obtained with this device. 相似文献

After tuning their message to suit their audience's attitude, communicators' own memories for the original information (e.g., a target person's behaviors) often reflect the biased view expressed in their message--producing an audience-congruent memory bias. Exploring the motivational circumstances of message production, the authors investigated whether this bias depends on the goals driving audience tuning. In 4 experiments, the memory bias was found to a greater extent when audience tuning served the creation of a shared reality than when it served alternative, nonshared reality goals (being polite toward a stigmatized-group audience; obtaining incentives; being entertaining; complying with a blatant demand). In addition, the authors found that these effects were mediated by the epistemic trust in the audience-congruent view but not by the rehearsal or accurate retrieval of the original input information, the ability to discriminate between the original and the message information, or a contrast away from extremely tuned messages. The central role of epistemic trust, a measure of the communicators' experience of shared reality, was supported in meta-analyses across the experiments. 相似文献

The aim of this study was to investigate the usefulness of convenience samples in research on interpersonal aggression among adults. It was hypothesised that convenience sampled targets of aggression differs from targets in general with regards to both demographic characteristics and degree of aggression exposed to. A convenience sample comprising support-seeking targets of workplace bullying was compared with a representative sample of Norwegian targets of bullying. The results showed that the two samples differed significantly on all demographic variables investigated, except gender. A far higher percentage of the convenience sample had blown the whistle on illegal, immoral or illegitimate practice at their workplace, whereas they also reported significantly more frequent and more intense exposure to aggression. The findings confirm that convenience samples have low external validity when generalising to the general population. Such samples should therefore mainly be used to investigate tendencies in, and the phenomenology of, interpersonal aggression, in studies where generalisability is not the principal objective. 相似文献

The information content of panoramic images II: view-based navigation in nonrectangular experimental arenas 总被引:2,自引:0,他引:2

Two recent studies testing navigation of rats in swimming pools have posed problems for any account of the use of purely geometric properties of space in navigation (M. Graham, M. A. Good, A. McGregor, & J. M. Pearce, 2006; J. M. Pearce, M. A. Good, P. M. Jones, & A. McGregor, 2004). The authors simulated 1 experiment from each study in a virtual reality environment to test whether experimental results could be explained by view-based navigation. The authors recorded a reference image at the target location and then determined global panoramic image differences between this image and images taken at regularly spaced locations throughout the arena. A formal model, in which an agent attempts to minimize image differences between the reference image and current views, generated trajectories that could be compared with the search performance of rats. For both experiments, this model mimics many aspects of rat behavior. View-based navigation provides a sufficient and parsimonious explanation for a range of navigational behaviors of rats under these experimental conditions. 相似文献

The aim of this paper is to use an integrative approach to identify the main correlates and/or predictors at different levels (personal, psychosocial, occupational and outside the workplace) of the burnout dimensions. The sample consists of 813 university professors. Results from statistical analyses show that there are, indeed, both common and specific predictors for the different facets of the syndrome. Specifically, while social support and optimism are selected to confirm all manifestations of burnout, other factors (work hours per week, time in the profession, hardiness, Type A behavioural pattern, life events, daily hassles) do increase the emergence of differential profiles. Lastly, findings are discussed and the main conclusions are presented. 相似文献

A recent number of studies have focused on the relations between psychosocial factors and sleep disturbances. Like other work-related stressors, workplace byllying is associated with several negative consequences. However, few studies have investigated the influence of workplace byllying on disturbed sleep. Insomnia is the most frequent sleep complaint. Several models have highlighted the importance of cognitive factors in the development and maintenance of insomnia. Cognitive styles such as psychological detachment and rumination may be relevant in this process. The aim of the present study is to examine the moderating role of psychological detachment and rumination on the relationship between workplace byllying and insomnia. To minimize the effect of common method variance, we tested our hypothesis using a research design in which we collected data at two points in time separated by 1 month. A total of 523 individuals responded to both phases, with 511 useable surveys. The results of the hierarchical multiple regression analysis provide evidence for the moderating role of psychological detachment and rumination in the workplace byllying process. Thus, these findings are in line with the cognitive models of insomnia. 相似文献
