ObjectivesDistracted walking is a major cause of pedestrian road traffic injuries, but little is known about how distraction affects pedestrian safety. The study was designed to explore how visual and auditory distraction might influence pedestrian safety.MethodsThree experiments were conducted to explore causal mechanisms from two theoretical perspectives, increased cognitive load from the distraction task and resource competition in the same sensory modality. Pedestrians’ behavior patterns and cortex oxyhemoglobin changes were recorded while they performed a series of dual tasks.ResultsFour primary results emerged: (a) participants responded more slowly to both visual and auditory stimuli in traffic, as well as walked more slowly, while talking on the phone or text messaging compared to when undistracted or listening to music; (b) when participants completed pedestrian response tasks while distracted with a high cognitive load, their response was significantly slower and poorer than when they carried out a lower cognitive load distraction task, (c) participants had higher levels of oxy-Hb change in cortices related to visual processing and executive function while distracted with a higher cognitive load; and (d) participants' responses to traffic lights were slower and resulted in a higher activation in prefrontal cortex and occipital areas when distracted by a visual distraction task compared to when distracted with an auditory task; similarly, brain activation increased significantly in temporal areas when participants responded to an auditory car horn task compared to when they responded to visual traffic lights.ConclusionsBoth distracting cognitive load demands and the type of distraction task significantly affect young adult pedestrian performance and threaten pedestrian safety. Pedestrian injury prevention efforts should consider the effects of the type of distracting task and its cognitive demands on pedestrian safety.  相似文献

In aiming sport contexts, the quiet eye (QE) - the final ocular fixation before movement initiation - is a crucial perceptual-cognitive skill. Indeed, an extended QE permits athletes to achieve high performances, aiding optimal attentional control, particularly in situations in which athletes are \"under pressure.\" Such situations are common in sport, especially when time runs out, and even just a few points can mean the difference between victory and defeat. Although QE has been widely investigated across several sports and tasks, no previous studies have considered both the role of time pressure and performance pressure on QE. The current study aimed to comprehend the effect of tough sport situations on QE characteristics. Accordingly, we tested basketball players (competitive-élites and semi-élites) in free throw trials, manipulating both the time available to perform the task and the relevance of the performance. The results showed that time pressure and performance pressure impaired QE characteristics, regardless of expertise levels. Also, time pressure led to a decrease in free throw accuracy. Interestingly, the match between task demands and the ability to cope seemed to play a role on QE, especially in the competitive-élite players, with negative QE characteristics (short and late) when task demands exceeded the ability to cope. These findings suggest that QE research and QE training protocols should account for time pressure, performance pressure, and the players' perceived ability to cope with the requested task.  相似文献

We experimentally approach the discursive dilemma to gain insight into people's procedural appropriateness judgments. We relied on a vignette in which three people had formed opinions about two skills (premises) of a candidate to decide whether to hire her/him (conclusion). The dilemma arises when different outcomes (hire vs. not hire) are achieved depending on whether the majority opinion is independently considered for each premise or for the global conclusion of each judge. Participants were asked to choose the procedure they thought to be more appropriate to reach a decision. In Experiment 1, we found a leniency effect (a bias to prefer the aggregation procedure that led to hiring the candidate), which was reduced by introducing the participant as a juror with an exogenously provided negative opinion about the candidate's skills. In Experiment 2, we replicated the opinion effect, even when subjects did not participate as jury members. In Experiment 3, we found that the leniency bias was only reduced when participants' negative opinion was aligned with a majority of negative premises, but not with a majority of negative conclusions. We discuss present findings in terms of the identification of empirical regularities that may affect people's procedural legitimacy judgments.  相似文献

What factors promote or hinder volunteering within organizations and groups? This paper simultaneously explores the impact of individual, contextual, and sociocultural variables on decision making in a special type of social dilemma: the volunteer's dilemma game (VDG). The VDG provides a controlled experimental method for studying volunteering behaviors in an anonymous interactive environment. We developed six variations of the VDG and administered them to economics students in five different cultures (Ntotal = 603). Among other things, these VDGs varied whether the potential benefits of volunteering were certain or uncertain. Although the overall level of volunteering did not vary substantially across most cultural groups, we found that culture interacted with the size and (un)certainty of the benefits associated with volunteering, to influence volunteering decisions. We also found that religiosity (but not religious affiliation per se) increases volunteering and that men are less likely to volunteer when the returns to doing so are certain. These results extend our knowledge of behaviors in the VDG, and their potential drivers, with clear implications for understanding how culture, individual characteristics, and context jointly influence prosocial behavior and coordination.  相似文献

Resource-based theory (RBT) posits that firms gain competitive advantage through bundles of valuable and rare resources and sustain that advantage over time when such resources are difficult to imitate or nonsubstitutable by competitors. Recent applications of RBT emphasize the role of managers in mobilizing and leveraging organizational resources and capabilities for achieving business objectives. The purpose of this research is to advance the sales literature by applying learning from two specific perspectives based on RBT that focus explicitly on managerial actions pertaining to resources and capabilities: resource orchestration and dynamic managerial capabilities. These perspectives provide insights into the role of sales managers as orchestrators of sales and nonsales resources for achieving sales, organizational, and customer outcomes. Consistent with the stated purpose, this research provides (1) a review of research on resources and capabilities in the sales literature, (2) an overview of resource orchestration and related research, (3) an overview of dynamic managerial capabilities and related research, (4) a research agenda and propositions based on research orchestration and dynamic managerial capabilities for further investigation on the role of sales managers as effective resource orchestrators in sales organizations.  相似文献

ABSTRACT

Knowledge justice provides a conceptual framework to apply principles of social justice in environments of competing interests regarding science. Both knowledge and its making can be seen as a good to be distributed, including all voices for whom the science will matter. In this framework, knowledge production is shared among a broader constituency of knowers representing both local and cosmopolitan voices. The problem of knowledge injustice can be seen in the U.S. government’s recent attempt to secure scientific knowledge about H5N1 or avian bird flu virus. The censorship produced a global debate between scientists and policy-makers over how to balance the nation-state’s desire for security with the life science’s tradition of open and shared research. This conundrum, known as the dual-use dilemma, obscures larger questions that lie outside of expert-centered domains—namely the concerns of many communities in the Global South struggling with the impact of the virus in their daily lives. An example of such counter-expertise is that of the backyard poultry farmer whose ways of knowing are foreign to science and policy experts who frame the ways in which knowledge about H5N1 should be developed, controlled, and used. While the H5N1 debate illuminated competing positions regarding knowledge production between powerful elites, it ignored the social justice inequities produced by the dual-use dilemma. The concept of knowledge justice provides a way of thinking about science that can include locally situated counter-expertise, disrupting the dual-use dilemma produced by competing dominant priorities of security and public health.  相似文献

This study contributes to research on organizational attractiveness and human resource management (HRM) by drawing on image theory to examine the effect of organizational characteristics (foreign vs. domestic company country‐of‐origin, HRM practices, organizational culture, and work environment) on organizational attractiveness perceptions by host country national (HCN) employees. Drawing on person–organization fit theory, we also examine the moderating effects of HCNs' demographic characters (age and gender), work‐related skills (English proficiency and international experience), and value orientations (individualism and risk aversion) between the relationship of these organizational characteristics and organizational attractiveness. A between‐subject scenario‐based experiment with 800 HCN employees in Japan suggest that not the company country‐of‐origin, but the local adaptation of organizational culture, HRM practices, and work environment influence HCNs' organizational attractiveness perceptions. HCNs' demographic characteristics, work‐related skills, and value orientations had moderating effects between these organizational characteristics and organizational attractiveness perceptions.  相似文献

道德判断对社会合作有重要意义。近20年来涌现出大量对道德判断的研究。经典的社会直觉模型和双加工模型已经不足以解释所有的研究发现。近年来,解释水平理论为道德判断的研究提供了一个新的视角。通过文献梳理发现,基于解释水平理论的道德判断研究可以分为两难的道德判断研究和一般的道德判断研究。两难的道德判断研究已经有了较为一致的结论,但是一般的道德判断研究还存在争议。解释水平影响道德判断的深层原因可能是通过关注点影响道德判断的标准。未来的研究可以着眼于跨文化研究和深层机制的剖析,为解释水平视角下的道德判断研究提供更多的实验证据,加深人们对道德判断的理解。  相似文献

Clinicians sometimes disagree about how much to honor surrogates’ deeply held cultural values or traditions when they differ from those of the host country. Such a controversy arose when parents requested a cultural accommodation to let their infant die by withdrawing life saving care. While both the parents and clinicians claimed to be using the Best Interests Standard to decide what to do, they were at an impasse. This standard is analyzed into three necessary and jointly sufficient conditions and used to resolve the question of how much to accommodate cultural preferences and how to treat this infant. The extreme versions of absolutism and relativism are rejected. Properly understood, the Best Interests Standard can serve as a powerful tool in settling disputes about how to make good decisions for those who cannot decide for themselves.  相似文献

Greene and colleagues [Greene, J., Sommerville, B. R., Nystrom, L. E., Darley, J. M., & Cohen, J. D. (2001). An fMRI investigation of emotional engagement in moral judgment. Science, 293, 2105-2108.] have revealed an apparent distinction in folk psychology between ‘up close and personal’ and ‘impersonal’ moral dilemmas. Reasoning about these types of dilemmas is purportedly supported by partially dissociable neural systems. However, further investigation of the data supporting this hypothesis indicated that only a small number of stimuli used by Greene et al. are driving the effect originally found. Implications of the apparent distinction initially reported and of other research in the domain of moral psychology are discussed.  相似文献
