This study examined the role of early visual experience and age in the recognition of emotional prosody among students with visual impairments in China. A total of 75 primary and junior high school students participated in the study. The ability of participants to recognize the prosody of four basic emotions (sadness, anger, happiness, and neutrality) was explored. The findings were as follows. (1) Early visual experience had a significant effect on the recognition of emotional prosody. The accuracy rate of students with congenital blindness was lower than that of students with adventitious blindness, and the performance of students with congenital blindness was lower than that of sighted students. The students with congenital blindness exhibited the slowest recognition speeds. (2) Age had a significant effect on the emotional prosody recognition accuracy of the sighted students, but it had no effect on the students with blindness.  相似文献

In the transition towards higher levels of vehicle automation, one of the key concerns with regards to human factors is to avoid mode confusion, when drivers misinterpret the driving mode and therewith misjudge their own tasks and responsibility. To enhance mode awareness, a clear human centered Human Machine Interface (HMI) is essential. The HMI should support the driver tasks of both supervising the driving environment when needed and self-regulating their non-driving related activities (NDRAs). Such support may be provided by either presenting continuous information on automation reliability, from which the driver needs to infer what task is required, or by presenting continuous information on the currently required driving task and allowed NDRA directly. Additionally, it can be valuable to provide continuous information to support anticipation of upcoming changes in the automation mode and its associated reliability or required and allowed driver task(s). Information that could support anticipation includes the available time until a change in mode (i.e. time budget), information on the upcoming mode, and reasons for changing to the upcoming mode. The current work investigates the effects of communicating this potentially valuable information through HMI design. Participants received information from an HMI during simulated drives in a simulated car presented online (using Microsoft Teams) with an experimenter virtually accompanying and guiding each session. The HMI either communicated on automation reliability or on the driver task, and either included information supporting anticipation or did not include such information. Participants were thinking aloud during the simulated drives and reported on their experience and preferences afterwards. Anticipatory information supported understanding about upcoming changes without causing information overload or overreliance. Moreover, anticipatory information and information on automation reliability, and especially a combination of the two, best supported understandability and usability. Recommendations are provided for future work on facilitating supervision and NDRA self-regulation during automated driving through HMI design.  相似文献

This paper reports on the results of a study exploring sibling stories of parental mental distress and the societal discourses that may have contributed to the adult siblings' sense-making. Four sibling pairs were purposively recruited and interviewed, using a narrative inquiry approach. Two main plots were constructed through analysis of the participants' narratives: ‘The story of us’ and ‘We are who we are because of what happened’. Results highlighted that the identity construction of each sibling and the collective identities of the sibling pairs are influenced by the parental mental health context. The findings also suggest a change in the siblings' meaning-making from childhood to adulthood. These findings are considered along with the implications for systemic practice and research.  相似文献

孔墨“俱道尧舜”但政治理想却截然不同,其主要原因在于两方面,首先是他们有着各不相同的历史传统和政治理想,其次是他们对于中国轴心时代的社会现实有着完全不同的认识和评价。两家显学的根本分歧在于“礼与食孰重”,儒家认为生活资料的匮乏是由于人的动物性欲望未能得到有效的遏制,因而特别强调了一整套礼仪制度对于文明的重要性。墨家则认为正是由于礼仪制度本身的维系严重消耗了社会的物质基础,才使得人们为了满足饥饿的食本能而不得不弱肉强食。这个思想史的问题至今仍未结束。  相似文献

采用复制法,通过聋人与听力正常人时距估计的对比实验研究,结果发现听觉经验缺失对时距估计有一定的影响:(1)两类被试在2000ms和10000ms的时距估计中,再现时距的平均数表现出了显著性差异。听力正常被试倾向于低估时距,聋人被试倾向于高估时距。(2)聋人被试不同时距再现相对误差率之间不存在显著性差异;听力正常被试时距再现相对错误率在2000ms与10000ms、30000ms存在显著差异,10000ms和30000ms之间差异不显著。  相似文献

易哲学发展史之一嬗变--陆王心学的易哲学思想探析   总被引:1,自引:0,他引:1  
陆王心学的易哲学思想的出现,伴随了一定的时代特点,可谓是易哲学史上继王弼义理易之后的一次深刻嬗变.这表现为其以心释易统易、工夫简易直截的鲜明特征,其中蕴涵了心学派易学对象数易及程朱义理易的解构以及为一般易学研究所忽略的易佛沟通问题.从陆王心学的易哲学思想里面,我们可以发现,心学在宋时的诞生以及它最终的衰微,同样不是一个偶然的现象,它在解构"传统"易学的同时也解构了自身.  相似文献

Introduction

Celiac disease is estimated to affect between 1 in 100 and 1 in 300 Caucasian subjects. Many quantitative studies have explored the issues encountered by these subjects; however, few studies have addressed the subjective and experiential dimensions of celiac disease.

Objective

The objective of this qualitative exploratory study is to expand current knowledge concerning the subjective experience of celiac disease and of a gluten-free diet in subjects diagnosed with celiac disease in adulthood.

Method

Data was collected through non-directive interviews with 14 subjects aged between 28 and 53 (M = 41.7, SD = 7.48).

Results

An interpretive phenomenological analysis identified various themes related to the experience of illness: (1) history of the disease, (2) symptoms, (3) nutrition, (4) perception of medical experiences, (5) relationships with family and friends, (6) psychological implications, and (7) consequences for daily living.

Conclusion

The results show the importance of developing a “mythology” (concerning the disease's origin) to enable the inclusion of the condition in the individual's on-going personal story.  相似文献

The moral error theorist claims that moral discourse is irredeemably in error because it is committed to the existence of properties that do not exist. A common response has been to postulate ‘companions in guilt’—forms of discourse that seem safe from error despite sharing the putatively problematic features of moral discourse. The most developed instance of this pairs moral discourse with epistemic discourse. In this paper, I present a new, prudential, companions-in-guilt argument and argue for its superiority over the epistemic alternative.  相似文献

Religious groups outside the West have displayed a positive correlation between faith and intellect-oriented reflection in contrast to the negative relationship found with American Christians. This study extended the analysis to Pakistani Muslims. University students (N = 180) responded to religious reflection scales along with measures of religious orientation and satisfaction with life. Faith- and intellect-oriented reflection correlated positively, and both displayed direct relationships with religious orientations and satisfaction with life. In multiple regression analyses, both combined to predict the intrinsic religious orientation, but faith-oriented reflection was the only significant predicter of other measures. These data further documented a compatibility between Muslim faith and intellect and supplemented other cross-cultural findings in suggesting that understandings of more conservative religious beliefs may require sensitivity not only to their content, but also to their cultural context.  相似文献

A focused review of the literature on reasoning suggests that mechanisms based upon contraries are of fundamental importance in various abilities. At the same time, the importance of contraries in the human perceptual experience of space has been recently demonstrated in experimental studies. Solving geometry problems represents an interesting case as both reasoning abilities and the manipulation of perceptual–figural aspects are involved.

In this study we focus on perceptual changes in geometrical problem solving processes in order to understand whether a mental manipulation in terms of opposites might help. Four conditions were studied, two of which concerned the search for contraries as an implicit or explicit strategy.

Results demonstrated that contraries, when used explicitly in solution processes, constitute an effective heuristic: The number of correct solutions increased, less time was needed to find a solution and participants were oriented towards the use of perception-based solutions—not only were perceptual solutions more frequent, but also, more specifically, the number of correct perceptual solutions increased. These last results concerning perception-based solutions were found both when participants were advised about the usefulness of the strategy and when they were not advised. Differences concerning which aspects of a problem were focused on during the solution process also emerged.  相似文献
