In this work, the tactual information transmission capabilities of a tactual display designed to provide stimulation along a continuum from kinesthetic movements to cutaneous vibrations are assessed. The display is capable of delivering arbitrary waveforms to three digits (thumb, index, and middle finger) within an amplitude range from absolute detection threshold to about 50 dB sensation level and a frequency range from dc to above 300 Hz. Stimulus sets were designed at each of three signal durations (125, 250, and 500 msec) by combining salient attributes, such as frequency (further divided into low, middle, and high regions), amplitude, direction of motion, and finger location. Estimated static information transfer (IT) was 6.5 bits at 500 mseC., 6.4 bits at 250 mseC., and 5.6 bits at 125 msec. Estimates of IT rate were derived from identification experiments in which the subject’s task was to identify the middle stimulus in a sequence of three stimuli randomly selected from a given stimulus set. On the basis of the extrapolations from these IT measurements to continuous streams, the IT rate was estimated to be about 12 bits/seC., which is roughly the same as that achieved by Tadoma users in tactual speech communication. 相似文献

Chinese philosophy views experience as intrinsically aesthetic. This world view could be elucidated through a consideration of John Dewey's aesthetics and features of Chinese art. Dewey's philosophy of art starts with an understanding of experience as ‘live processes’ of living creatures interacting with their environment. Such processes are autopoietic in being self‐sustaining, ever‐changing, capable of increasing complexity, capable of generating novelty, direction and progress on its own. Its autopoietic character is a precondition of the aesthetic in the process of experience. An aesthetic experience is rhythmic, focused, consummatory, and reaches beyond the transitory boundaries of concrete existence. The aesthetic is not confined to what is conventionally identified as art. Most important, the ethical‐political, the natural and the cosmic all have an aesthetic aspect, as the paper attempts to show by examining classical Confucianism. 相似文献

汉字的视觉识别过程:对形码和音码作用的考察 总被引:12,自引:1,他引:11
本实验应用启动条件下的词汇判断法,探讨了字形和语音在汉字视觉识别过程中的作用。实验发现,当启动词中的某个成分字和目标字形状相似时,被试对目标字的反应速度显著加快,表明特征分析是汉字识别的必经阶段;启动词中的多音字不但会促进被试对和其适当读音相近的目标字的反应,而且会促进被试对和其不适当读音相近的目标字的反应。这就明,在到达心理词典之前,熟悉的中文字词的语音特征已经得到了自动的激活。 相似文献

以一位第一次进行胼胝体前部切开,第二次作后部切开的胼胝体全切断患者为被试,在第二次手术前后进行了Ⅰ。左右单侧操作检查,和Ⅱ。两半球之间感觉信息传递两类神经心理学实验。结果提示:后部切断前,左右侧操作没有明显的差异。同时,视觉和触觉的感觉信息的传递基本正常。在后部切断后,命名作业呈右视野和右手优势,图形临摹左手似乎较好,这时视觉和触党的感觉信息的传递发生了障碍。左视野和左手命名高于随机水平,讨论了这一结果与右脑语言的关系。方位比较等多个实验提供了支持两半球协同活动理论的证据。 相似文献

Unlike our counterparts in Europe who have rewritten their specific cultural philosophical heritage, American feminists have not yet critically reappropriated our own philosophical tradition of classical American pragmatism. The neglect is especially puzzling, given that both feminism and pragmatism explicitly acknowledge the material or cultural specificity of supposedly abstract theorizing. In this article I suggest some reasons for the neglect, call for the rediscovery of women pragmatists, reflect on a feminine side of pragmatism, and point out some common features. The aim is to encourage the further development of a feminist revisioning of pragmatism and a pragmatist version of feminism. 相似文献

Musicians and nonmusicians indicated whether a two-note probe following a tonally structured melody occurred in the melody. The critical probes were taken from one of three locations in the melody: the two notes (1) ending the first phrase, (2) straddling the phrase boundary, and (3) beginning the second phrase. As predicted, the probe that straddled the phrase boundary was more difficult to recognize than either of the within-phrase probes. These findings suggest that knowledge of harmonic structure influences perceptual organization of melodies in ways analogous to the influence of clause relations on the perceptual organization of sentences. They also provide evidence that training plays an important role in refining listeners’ sensitivity to harmonic variables. 相似文献

Rape crisis centers have undergone significant changes since their birth during the feminist movement of the 1970s. As has happened with many other radical social movements, there is growing evidence that the antirape movement has become more institutionalized. This research used a combination of quantitative and qualitative methods to examine the current structure and functions of a national random sample of 168 rape crisis centers. An organizational-level model predicting involvement in three types of social change activities was tested: (a) participation in public demonstrations to raise awareness about sexual assault; (b) political lobbying for violence against women legislation; and (c) primary prevention programs to eliminate sexual violence against women. Results of logit modeling suggested that how long a rape crisis center had been in existence moderated the relationships between organizational characteristics and involvement in community activism. Findings of this study suggest that although many of today's centers bear little resemblance to the grass-roots collectives of years past, rape crisis centers have been remarkably adaptive in weathering changing political climates to continue to provide comprehensive services for rape victims. 相似文献

Two experiments were performed in an attempt to examine the contribution of the exploratory experience to performance on Maier's 3-table spatial problem-solving task. In the first experiment, the runway configurations were altered between exploration and testing. It was found that following an initial impairment animals exposed to the altered runway configurations could perform as well as animals not confronted with an altered runway configuration on the test trial. In the second experiment, animals were allowed to explore only elements of the problem space. Exploration of either the runways only or the tables only led to unsuccessful performance on the 3-table task. The results of both experiments were related to current theory of cognitive mapping. 相似文献

Trust in supervisor and trust in organization are argued to be distinct but related constructs, each with its own set of antecedents and outcomes. Empirical field results supported the proposition. Although trust in supervisor and trust in organization were positively and significantly correlated, trust in supervisor was more strongly associated with proximal variables (ability, benevolence, and integrity of supervisor), whereas trust in organization was more strongly correlated with global variables (perceived organizational support and justice). This conclusion held despite the inclusion of proximal variables in the regression on trust in organization and the inclusion of global variables in the regression on trust in supervisor. In addition to the differential antecedents of trust in supervisor and trust in organization, the outcomes for both variables were different. Trust in supervisor was related to increased innovative behavior and satisfaction with supervisor, and trust in organization was related to higher organizational commitment and lower intention to leave. Therefore, the authors provide clear preliminary data on the distinctiveness of trust in supervisor and trust in organization. One implication of this set of results is that organizations should adopt a more holistic approach in building trust, which can be achieved by focusing on the various constituents of the organization and the various levels (e.g., the supervisor level and the organizational level). 相似文献
