Several driving simulators have been developed which range in complexity from PC based driving tasks to advanced "real world" simulators. The AusEd driving simulator is a PC based task, which was designed to be conducive to and test for driver fatigue. This paper describes the AusEd driving simulator in detail, including the technical requirements, hardware, screen and file outputs, and analysis software. Some aspects of the test are standardized, while others can be modified to suit the experimental situation. The AusEd driving simulator is sensitive to performance decrement from driver fatigue in the laboratory setting, potentially making it useful as a laboratory or office based test for driver fatigue risk management. However, more research is still needed to correlate laboratory based simulator performance with real world driving performance and outcomes. 相似文献

Coloring only a single letter in the Stroop task can result in a reduction or elimination of Stroop interference. The present experiments were designed to test whether this modulation of Stroop interference occurs at all letter positions. Specifically, we investigated whether Stroop interference was reduced when the colored letter occupied the optimal viewing position (OVP). The experiments show that Stroop interference is not reduced at the OVP (Experiment 1) and that Stroop interference at the OVP is significantly greater than at other letter positions (Experiments 1 and 2). This finding has important theoretical and methodological consequences for studies of automatic processing in visual word recognition. 相似文献

In this paper, I defend the claim that an object can have a property only if it exists from two arguments, both of which turn
on how to understand Plantinga’s notion of the α-transform of a property.

Current theory assumes that individuals only use information from the immediate environment to perform relative arrival-time judgment tasks. This article presents a theoretical analysis of the memory requirements of this task. The authors present an analysis of the inputs to the memory system and the processes that map those inputs onto outputs. The analysis generates a set of predictions regarding the specificity of transfer and the role of context during learning. In 3 experiments, participants decided whether pairs of aircraft would violate a minimum separation standard or pass each other safely. Participants were presented with pairs of aircraft in which properties of the pair varied along 3 structural and 3 surface dimensions. Contexts were defined by the co-occurrence of specific values along stimulus dimensions and the use of a neutral label. The results suggest that transfer was limited by the dimensions that were varied in training and the context in which those dimensions were varied. The discussion focuses on the problems that complex tasks like relative judgment pose for associative learning mechanisms and the development of precise models of cognition. 相似文献

Nationalist and ethnic conflicts are a continuing source of tension in the post–Cold War period. The underlying factors affecting such conflicts are threat perception, ethnic security dilemmas, and lack of trust between nationalist/ethnic groups. The challenge is to find solutions to these conflicts. International institutions can establish trust and reduce the ethnic security dilemma by providing multiple forums of representation, promoting overlapping identities, and pooling sovereignty. Pooling sovereignty across a number of international representative bodies leads to increased access to governmental policymaking, with each party having a stake in government, and leads to a reduction in political tension and conflict. Thus, international parliamentary institutions may provide a solution to these conflicts. The British-Irish Peace Agreement (Good Friday Agreement) of 1998 is examined as an illustration of this argument. 相似文献

The neurosteroid dehydroepiandrosterone (DHEA) is a powerful inhibitor of aggression in murine models when given for 15 days and potentially may be useful in the management of inappropriate human aggression. Although the biosynthesis and metabolism of DHEA have been described, little is known about the potential effect of the steroidal environment during sexual differentiation on the subsequent response to DHEA. Whether prenatal androgen exposure influences the subsequent response to DHEA was assessed by comparing the effect of DHEA (80 μg/d) on aggression in female offspring where dams were treated with 1, 10, or 100 μg of testosterone (T) on days 15 to 18 of gestation (Experiment I) or that developed in different uterine positions (Experiment II). The results showed that DHEA decreased attack behavior in general and that the 100‐μg prenatal T treatments enhanced the antiaggressive effect of this neurosteroid. Neither the lower doses of exogenously administered T nor the uterine position led to an enhanced response to DHEA. In addition, whether DHEA produced changes in social and nonsocial activities was examined. In the 100‐μg T females, DHEA increased the duration of the former and decreased the frequency and duration of the latter, indicating that it was not a general decrement in behavioral expression that mediated the enhanced response to the antiaggressive effect of DHEA. In the second experiment, DHEA treatment led to increased frequencies of social nonaggressive and nonsocial activities. However, the uterine positions × treatment interactions were not significant, demonstrating that contiguity to male fetuses did not differentially affect the response to DHEA. Aggr.

The Continuity Test is the principle that a proposed distribution of resources is wrong if it treats someone as disadvantaged when they don't see it that way themselves, for example by offering compensation for features that they do not themselves regard as handicaps. This principle — which is most prominently developed in Ronald Dworkin's defence of his theory of distributive justice — is an attractive one for a liberal to endorse as part of her theory of distributive justice and disadvantage. In this article, I play out some of its implications, and show that in its basic form the Continuity Test is inconsistent. It relies on a tacit commitment to the protection of autonomy, understood to consist in an agent deciding for herself what is valuable and living her life in accordance with that decision. A contradiction arises when we consider factors which are putatively disadvantaging by dint of threatening individual autonomy construed in this way. I argue that the problem can be resolved by embracing a more explicit commitment to the protection (and perhaps promotion) of individual autonomy. This implies a constrained version of the Continuity Test, thereby salvaging most of the intuitions which lead people to endorse the Test. It also gives us the wherewithal to sketch an interesting and novel theory of distributive justice, with individual autonomy at its core. 相似文献
