The control of responding by auditory stimuli: interactions between different dimensions of the stimuli. 总被引:1,自引:1,他引:0 下载免费PDF全文
Sounds have position in addition to other dimensions, such as intensity and frequency. Position rapidly gains control of spatially contiguous responses and this may interfere with control of responding by other acoustic dimensions. These experiments investigated interference of a tone-noise discrimination by the discrimination of acoustic position. Squirrel monkeys were studied when responding was differentially reinforced in the presence of both spectral content (tone-noise) and positional differences between the stimuli, and when responding was differentially reinforced only in the presence of spectral differences. Under the first condition, responding rapidly came under the control of the position of the noise in the two monkeys tested. The position of the tone controlled responding in one monkey; in the second monkey, responding came under the control of the spectral content of the tone. Under the second condition, responding was initially under the control of the noise in all three monkeys tested. This persisted for the duration of the condition for two of the monkeys; in one monkey, responding came under the control of the spectral content of the noise. Under the second condition, responding was also initially under the control of the position of the tone for all monkeys, but control by spectral content of the tone relatively rapidly developed in two of three monkeys. 相似文献

Duncan等人认为,当目标和干扰子之间差异越大且干扰子彼此之间差异越小时,则目标搜索越快。他们的结论定性地描述了目标搜索斜率(反应时间对呈现项目数的函数)的决定因素。笔者从方位维度刺激关系方面进一步定量探究该问题,并提出决定因素为g(T, D, n)(目标方位和干扰子方位间的函数关系)。实验结果证实目标搜索斜率是由g(T,D,n)值决定,目标搜索斜率随g(T, D, n)值增大而减小,相同g(T, D, n)值条件的目标搜索斜率无显著差异 相似文献

Ever since Plato's famous attack on artists and poets in Book 10 of The Republic, lovers of literature have felt pressed to defend poetry, and indeed from ancient times down to the present, literature and art have had to fight various battles against philosophy, religion, and science. After providing a brief overview of this conflict and then arguing that between poetry and science there are some noteworthy similarities—that is, that some of the basic mental structures with which the scientist studies the “text” of nature (facts, laws, theories) find their counterparts in ways an informed reader studies the poetic text, I develop what I see as the most important differences between poetry, on the one hand, and science, philosophy, and theology, on the other. These differences lie chiefly in two areas: (1) in the stance that each takes toward language itself and (2) in the stance each takes toward that ancient polarity between the one and the many. The aim of my argument is neither to privilege poetry over the other modes of knowing the world nor to grant, particularly to science in its reductive “objectivity,” a higher epistemological status than that accorded to poetry and the arts. Instead, I wish to argue that science, by pushing the boundaries of knowledge about the material world, shows the poet, as well as the theologian, some of the more important work to be done and that poetry, with its emphasis on the particular over the abstract and on the ambiguities and paradoxes of language as inherently metaphorical, serves science and religion by providing a caution against the naive acceptance of language as literal and the consequent enthrallment to the power of absolutes and totalizing abstractions. 相似文献

人格维度与注意分配的关系及其选拔意义 总被引:6,自引:0,他引:6
本研究以210名男性大学生为被试,EPQ确定人格维度,微机测量注意分配,运用正交设计实验与区组实验相结合的方法综合论述了人格维度与注意分配的关系发现:E、E×N、P×E对注意分配有显著影响,N有一定影响,P和P×N的影响不显著。各影响因素的重要性顺序:E×N→P×E/E→N→P→P×N/误差,绘制了单项人格维度与注意分配关系简图。确定了三种人格维度的最佳组合型(注意分配可望最优):P1N2E1,次佳组合型:P3N2E1,最差组合型:P2N3E1,各型注意分配均值分别为0.702、0.680、0.309,本文探讨了实验结果的选拔意义,认为可从个体EPQ的结果来估测其注意分配能力,这在职业心理选拔中有重要应用价值。 相似文献

Modernity, a focal point of interest in our time, means the cultural schemata and mechanisms of social action stemming from
the Enlightenment and the modernization process. It is a set of new and “man-made” rationalized mechanisms and rules for human
societies that naturally grow beyond geographical boundaries. The interrelated dimensions of modernity may be roughly grouped
into “intellectual” and “institutional” categories including subjectivity and individual self-consciousness, a spirit of rationalized
and contracting public culture, modernity in sociohistorical narratives as an ideology, rationalization of economic operations,
bureaucracy in administrative management, autonomy of the public sphere, and the democratization and contraction of public
power. Modernity is inherently contradictory and risky, yet until now there has been no sign of an end in sight. It remains
to be the major support and dynamic in keeping human society running. Let us beware of superficial judgment when reflecting
upon theoretical critiques of modernity and try to grasp the great challenges and opportunities of globalization—essentially
a process of modernity.

两个实验分别考察外显和内隐言语记忆中的特征维度信息对基于维度的视觉选择性注意的自动引导作用。实验一要求被试在言语工作记忆(外显言语记忆)保持阶段完成一个视觉注意任务,结果发现了显著的一致性效应,即记忆任务相关维度和注意任务相关维度不一致条件下的注意任务反应时要显著慢于两者一致条件下的反应时;实验二采用go/no-go任务以考察内隐言语记忆对视觉选择的影响,结果也发现了类似的一致性效应。这些结果表明外显和内隐言语记忆中的抽象维度信息自动引导注意选择视场中与之匹配的视觉维度,而不管该维度是否为当前注意任务的相关维度。 相似文献

全球性的生态环境问题不仅是人与自然关系的失调,更从根本上反映出人与人之间社会关系的矛盾与冲突,其关涉到人类生命质量与人类文明的发展,受到自然科学、生物学、伦理学、社会学等学界的高度关注。将生态与环境保护纳入生命伦理的研究视域,从处理人与自然关系的人类环境价值观视角、人与人关系的人类道德行为规则视角探索生态与环境保护的实践路径,不仅是对人类走出生态困境的有益探索,同时对于生命伦理亦具有深远的意义。 相似文献
