The rapid development of urban roads has resulted in an increase in the amount of information that needs to be displayed on traffic signs. The overloading of information on traffic signs may increase drivers’ visual cognition burden and cause driving errors. It could be an important factor affecting driving safety and result in accidents. To enable drivers to cognize traffic signs, the information density that they could endure under reasonable workload levels should be determined. In this study, we designed and implemented trials to analyze drivers’ visual working memory load (VWML) caused by different information densities (including stimulus intensity (SI) and interval time of stimulus (IS)) of traffic signs. Twenty-four paid participants (12 females) with a mean age of 23.38 years (SD = 1.38) participated in laboratory simulation trials based on the memory retrieval approach. Subjective ratings (rating scale mental effort (RSME)), and performance measurement based on reaction time and accuracy of information-matching task were measured to reflect drivers’ VWML at different information densities. The results show that information density is an important factor affecting drivers’ VWML. The following are the significant observations of the study: (1) The subjective ratings on mental effort increased with increase in the SI. Meanwhile, it first decreased and then increased with increase in the IS. (2) The response accuracy results show that a high accuracy (≥0.7) was achieved by drivers in an IS of 15 s when the SI was at most 14.16 bit/m2. Correspondingly, the drivers underwent less mental workload as a result of their better short-term memory characteristic. (3) The mean reaction time was over 1800 ms when the SI was over 14.16 bit/m2. This indicated a reduction in the information-processing capability of the drivers. The results indicate that cognition of information of unreasonable density on traffic signs would increase drivers’ VWML. This would, in turn, result in an increase in their reaction time and decrease in accuracy. The threshold of information density was also determined through the experiment. It would satisfy the information demand of drivers and prevent information redundancy. The results contribute to an understanding of drivers’ VWML while cognizing traffic signs with different information densities and provide safety, effectiveness, and information continuity considerations for the design and setting of traffic signs.  相似文献

When talking about automation, “autonomous vehicles”, often abbreviated as AVs, come to mind. In transitioning from the “driver” mode to the different automation levels, there is an inevitable need for modeling driving behavior. This often happens through data collection from experiments and studies, but also information extraction, a key step in behavioral modeling. Particularly, naturalistic driving studies and field operational trials are used to collect meaningful data on drivers’ interactions in real–world conditions. On the other hand, information extraction methods allow to predict or mimic driving behavior, by using a set of statistical learning methods. In simple words, the way to understand drivers’ needs and wants in the era of automation can be represented in a data–information cycle, starting from data collection, and ending with information extraction. To develop this cycle, this research reviews studies with keywords “data collection”, “information extraction”, “AVs”, while keeping the focus on driving behavior. The resulting review led to a screening of about 161 papers, out of which about 30 were selected for a detailed analysis. The analysis included an investigation of the methods and equipment used for data collection, the features collected, the size and frequency of the data along with the main problems associated with the different sensory equipment; the studies also looked at the models used to extract information, including various statistical techniques used in AV studies. This paved the way to the development of a framework for data analytics and fusion, allowing the use of highly heterogeneous data to reach the defined objectives; for this paper, the example of impacts of AVs on a network level and AV acceptance is given. The authors suggest that such a framework could be extended and transferred across the various transportation sectors.  相似文献

In eight studies, we tested the prediction that making choices for others involves less loss aversion than making choices for the self. We found that loss aversion is significantly lessened among people choosing for others in scenarios describing riskless choice (Study 1), gambling (Studies 2 and 3), and social aspects of life, such as likeably and status (Studies 4a–e). Moreover, we found this pattern in relatively realistic conditions where people are rewarded for making desirable (i.e., profitable) choices for others (Study 2), when the other for whom a choice is made is physically present (Study 3), and when real money is at stake (Studies 2 and 3). Finally, we found loss aversion is moderated when factors associated with self–other differences in decision making are taken into account, such as decision makers’ construal level (Study 4a), regulatory focus (Study 4b), degree of information seeking (Study 4c), omission bias (Study 4d), and power (Study 4e).  相似文献

采用Oddball范式考察听视跨感觉通道和听感觉通道中“无关刺激”或“无关属性”的信号提示对新异干扰的影响。实验1和实验2分别比较了听视跨通道和听通道中时间事件提示、时间提示和事件提示三种条件。结果表明:(1)时间提示条件下新异干扰效应消失, 而事件提示条件下新异干扰效应仍存在。无关刺激意外变化引起的靶任务行为受损, 不仅与偏差刺激的小概率和新颖性有关, 而且与干扰刺激与靶子间提示信号关联有关, 这种提示关联中事件发生的提示功能比时间间隔的提示功能更为重要。(2)听通道下新异干扰与视听跨通道结果一致, 无关属性也会起到提示信号作用, 同样事件提示功能比时间提示功能更重要。  相似文献

Diversity can enhance as well as disrupt team performance. Diversity beliefs and climates may play an important moderating role in these effects, but it is unclear what form these should take to promote the positive effects of diversity. Addressing this question in an integration of research in team cognition and diversity, we advance the concept of diversity mindsets, defined as team members’ mental representations of team diversity. These mindsets capture diversity-related goals and associated procedural implications for goal achievement. We develop theory about the accuracy, sharedness, and awareness of sharedness of mindsets as moderators of the diversity-performance relationship. We also identify the determinants of these aspects of diversity mindsets. Finally, we discuss the implications of our model for the management of diversity.  相似文献

This study examined the influence of perceived emotional intelligence (PEI) and intrusive thoughts on emotional responses following a stressful event. PEI was assessed on 144 participants using the Trait Meta-Mood Scale (TMMS). The TMMS assesses perceived ability to: (1) attend to moods (Attention); (2) discriminate clearly among moods (Clarity); and (3) regulate moods (Repair). The main purpose of this paper was to examine the relationship between PEI, intrusive thoughts, and adjustment to an acute stressor induced experimentally in the laboratory, on two separate days. Finally, we examined the relationship between PEI, Inhibition, and Empathy. Results indicated that Clarity influences emotional responses on Day 1, and Repair affects emotional responses on Day 2 indirectly via intrusive thoughts, which act as a mediator. Significant associations were obtained between the three factors of the TMMS with Empathy and Inhibition. These findings suggest that individuals with higher emotional Clarity and Repair will experience less negative emotional responses and intrusive thoughts after an acute stressor, which enables them to adapt more readily to the experience.  相似文献

Relatively little is known about the integration of people's fear-related dispositions and their expectations about stressful events. This research used information integration theory to examine how participants’ anxiety sensitivity and event expectancy are integrated to determine their social anxiety. Three studies were conducted—two with university students and one with anxiety clinic patients—in which participants were presented with multiple scenarios of a socially embarrassing event, each representing a different degree of event probability, from which subjective expectancies were derived. Independent variables included anxiety sensitivity (low, moderate, high) and event expectancy (low, medium, high, no probability information). Participants were asked to indicate their anxiety (dependent measure) in each expectancy condition in this 3 × 4 mixed, quasi-experimental design. The results of all three studies strongly suggest that anxiety sensitivity and event expectancy are integrated additively to produce social anxiety. Additional results and their implications for the treatment of anxiety-related disorders are also discussed.  相似文献

We examined the development of children's understanding of beliefs and emotions in relation to parental talk about the psychological world. We considered the relations between parent–child talk about the emotions of characters depicted in a picture book, false belief understanding and emotion understanding. Seventy-eight primarily Caucasian and middle-class parents and their 3- to 5-year-old children participated (half boys and half girls). The emotions talked about were relatively simple, but the complexity of the situation varied in terms of whether or not an understanding of beliefs was required to understand the emotion. Talk about the belief-dependent aspects of the emotions of picture book characters predicted children's false belief understanding, whereas talk about non-belief-dependent aspects of these emotions predicted children's emotion understanding. We argue that these data suggest that the development of children's understanding of beliefs and emotions is intertwined with learning to talk about the psychological world.  相似文献

ABSTRACT

The exponential growth in information resources and the new demands of the information age have put increasing demands upon faculty and students to access appropriate information quickly, to process that information with critical thinking skills, and to communicate both verbally and in writing a product that is practical, interesting, and meaningful. The job of teaching of research methods must include the integral components of an information literacy program. Students need to be encouraged to expertly retrieve the information required for the writing of a paper. They must be helped to think critically, synthesizing ideas and concepts from the numerous information sources.

It is vital that the faculty and librarian at Seminary of the East work together to develop a comprehensive information literacy program that is not only supported by both faculty and library staff, but periodically evaluated to validate the program and to measure its progress in addressing the information literacy needs of both students and faculty.  相似文献

This article presents a segment of the results gathered in a doctoral study that investigated information needs and behavior of Catholic priests in Croatia. The study focused on parish priests in particular and their information needs and behavior in the liturgy and care-giving role. The research was conducted with the help of quantitative and qualitative methodology. Print questionnaires were filled out by 327 respondents, while in the follow-up interviews 20 respondents took part. Research results show that respondents, in the care-giving role and liturgy, require information about theology, general culture, psychology, and pedagogy. More than half of respondents find information for liturgy on religious websites and in their personal parish libraries. However, in their care-giving role they seek information most often from their parishers, members in parish pastoral and economic boards, and from colleagues at their regular meetings organized by the (arch)diocese. Both in liturgy and care-giving role, respondents use religious publications to a much larger degree than secular books, magazines, or newspapers. The respondents explained that in liturgy they consult colleagues and parishers in order to exchange advices and ideas, while in the care-giving role some respondents also prefer to seek an advice from an expert in specific field. The results of this study can help Catholic Church and theological faculties when preparing the information literacy courses for future parish priests.  相似文献
