Two experiments examine the effect of multiple synthetic voices in an e‐commerce context. In Study 1, participants (N= 40) heard five positive reviews about a book from five different synthetic voices or from a single synthetic voice. Consistent with the multiple source effect, results showed that participants hearing multiple synthetic voices evaluated the reviewed books more positively, predicted more favorable public reaction to the books, and felt greater social presence of virtual speakers. The effects were mediated by participants’ feelings of social presence. The second experiment (N= 40) showed that the observed effects persisted even when participants were shown the purely artificial nature of synthesized speech. These results support the idea that characteristics of synthetic voices in doubly disembodied language settings influence participants’ imagination of virtual speakers, and that technological literacy does not hinder social responses to anthropomorphic technologies such as text‐to‐speech (TTS). 相似文献

上海市健将级运动员的智力状况分析 总被引:1,自引:1,他引:0
本课题研究的对象是上海市31名(其中男17名,女14名)年龄在19—29岁的健将级运动员,他们所从事的运动项目有:篮球、手球、棒球、技巧、射箭、跳高、撑杆跳高、跳远、标枪、中长跑、短跑和十项全能等。为了揭示他们的智商(IQ)和智力结构,我们运用了我国修订的韦克斯勒成人量表对他们逐个进行智力测验。结果表明:(1)所测健将级运动页的言语智商(VIQ)、操作智商(PIQ)和总智商(FIQ)的平均值都在105—110之间,男女性别无明显差异;(2)智商值达到120以上的运动员,他们的技能水平也相应地较高,特别是十项全能、技巧和篮球运动员;(3)健将级运动员的智力结构是全面和完好的。 相似文献

There is usually a long period of time between infection with the AIDS virus and manifestation of symptoms. Asymptomatic patients often would benefit from elective surgery for diseases such as arthritis which are unrelated to their infection. The surgeons' decisions to accept the risks to themselves, their spouses, and their operating teams in order to relieve pain and suffering appear to be based upon two covenants; one concerns their role within the doctor-patient relationship, and the other concerns their relationship to what they see as the ultimate meaning in life. 相似文献

立体视觉的心理物理和VEP比较研究 总被引:2,自引:0,他引:2
心理物理试验是研究立体视觉的主要方法。70年代VEP开始用于体视研究,并取得许多结果。由于VEP信号复杂,这些结果不能令人满意。本文使用心理物理试验和VEP对比方法对体视加以研究。我们的结果是:VEP波形中第一个正峰与刺激图形的亮度有关;N_2峰和P_3峰的潜伏期对判断体视存在与否有重要价值;本试验确定N_2峰潜伏期在体视存在时约为240ms—280ms,无体视存在时约为290ms—310ms;P_3峰潜伏期在体视存在时约为280ms—310ms,无体视存在时约为340ms—360ms;体视存在时的VEP与无体视存在时的VEP的互相关系数小于0.1;有体视的VEP其功率谱密度在8Hz附近有一峰;心理物理试验中使用强制选择得到的结果从VEP波形比较中可以确认是可靠的;有体视的VEP其N_2和P_3的潜伏期随视差变化呈现规律性改变。 相似文献

Adherents to the traditional model of alcoholism explain alcoholic behavior as a consequence of alcoholism. Alcoholism is identified as an unseen, unmeasured entity inherent in alcoholics. This concept parallels the thinking of Copernicus, Kepler, Galileo, and Newton, who believed in an unseen, unmeasurable creator behind the physical world. These traditional approaches contrast with the emergent model of alcoholism and twentieth-century scientific thought. Emergent scientific model adherents explain alcoholic behavior without resort to unseen factors. Since the traditional and emergent scientific models begin with different assumptions, model adherents experience communication difficulties. Future developments with determine which model will dominate the field of alcohol studies and treatment. 相似文献

Religious and spiritual issues in mental health are explored in the context of four conceptual models: the medical, the nursing, the humanistic, and the pastoral. This is done by looking at each model in terms of content, diagnostic focus, language and treatment goals, and primary qualities in the health provider.The models are illustrated by case studies gathered from a multidisciplinary setting. The discovery that each model can incorporate the religious and spiritual dimension in mental health care, but that each model does this in distinctive ways, is a key point. 相似文献

本研究在不同背景照度条件下对不同大小、不同对比度的兰道尔环的辨认进行了实验。主要结果表明:(1)视觉作业水平的提高依赖于视标大小、对比度和背景照度这三个变量及其相互间的关系;在视觉作业水平一定时,视标大小、对比度和背景照度存在着两两对应的代偿关系;(2)以中国人为被试的RCS结果与国外欧美人为被试的CIE推荐的结果基本一致,但前者在低亮度范围内要明显高于后者。 相似文献

This paper is a general survey of ethical issues related to the artificial heart. It begins by looking at the history of funding of the artificial heart program through the National Institute of Health in 1965. Attention is paid to the problem of the lack of planning related to social, ethical, economic, and legal implications. The paper then deals with three areas of ethical concerns. They are those issues relating to the experimental versus therapeutic benefits, the cost, and public involvement with a private interest. 相似文献

The current paper examined the temporal linkage of internalizing symptoms among parent-adolescent dyads during the beginning of the COVID-19 pandemic, and whether COVID-19-related concerns were associated with parent-adolescent linkage of symptoms. Using a 5-week survey-based study, parent-adolescent dyads filled out weekly surveys measuring COVID-19 concerns and internalizing symptoms. Parent and adolescent depressive symptoms did not change over time; however, adolescents experienced decreases in anxiety. Parent-adolescent dyads exhibited linkage in depressive symptoms but not anxiety symptoms. However, linkage in anxiety symptoms varied by parent's COVID-related stress. Study findings provide insight into how COVID-19 disruptions impacted family well-being during adolescence. 相似文献
