Squirrel monkeys (Saimiri sciureus) and titi monkeys (Callicebus moloch) were tested in three two-choice visual discrimination experiments. Although, on average, squirrel monkeys performed more accurately than titis, the range of response accuracies in the two species overlapped considerably in all three experiments and changes in response accuracy over test sessions and across experiments were similar in the two species. Thus, the species shared several behavioral characteristics expected of New World primates in this setting. Squirrel monkeys’ performance appeared to be more affected than titis’ by task difficulty, and squirrel monkeys were individually less consistent than titis. These differences were associated with higher activity levels and briefer overt attentiveness to the repetitive task in squirrel monkeys and, conversely, with lower activity levels, slower working speeds, and sustained interest in the task in titis. The associated differences are discussed in relation to each species performance in other laboratory settings and the characteristic patterns of foraging and use of space in nature. 相似文献

A theoretical scheme was suggested which distinguished between absolute and relative class concepts and differentiated class from relational concepts. Four monkeys were trained to respond differentially to green and nongreen objects (absolute class) and four responded differentially to odd and nonodd objects (relative class). All monkeys met stringent criteria of performance on their respective tasks, the green-nongreen group in a median of 600 trials and the odd-nonodd group in a median of 1,600 trials (p = .014). Possible explanations for the performance differences and some implications of the theory for comparative, nonhuman conceptual research were discussed. 相似文献

The notion of multiculturalism is vital in our global society. The emergence of efficient and effective distance learning technologies has permitted the integration of innovative techniques in the delivery of multicultural content to individuals who need flexible and convenient education and training opportunities. Strategies form the instructional foundation that promotes engagement of learners. Integral to these strategies are those that relate to personal belief systems and extension of those belief systems to behaviors. This article will add new ways of teaching and learning in the areas of diversity and multiculturalism by offering a model for building highly supportive, engaging online environments, where instructors, trainers, and instructional designers use multiple strategies to build virtual environments that foster a sense of dignity, respect, and understanding: all critical elements in a global environment. 相似文献

资本主义是在周期性经济危机和周期性繁荣交替中前进的,由危机向繁荣的转化表明资本主义尚有能力容纳生产力的发展。世界市场的深化和扩张不仅成为资本主义转移经济危机的手段,也为资本主义向社会主义的转变准备了条件。作为资本主义经济运行的载体和指示器,世界市场的扩张与资本主义的阶段性发展基本同步,其发展的极端不平衡性是资本主义极端不合理性的体现。社会主义作为世界历史性的存在,只有在积极利用资本主义世界市场发展的成果,并化解其危机的基础上才能实现。 相似文献

In responding to Covid-19 anatomists have succeeded in adapting their teaching to online delivery. However, long-term reliance on this mode of teaching raises the prospect that transferring the whole of the learning environment to an impersonal digital world will lead to loss of anatomy’s humanistic side. In looking to a future increasingly dependent upon digital input to teaching, a number of roadblocks are identified. These are: the peril of abandoning the ethos of anatomy; for the workload of staff and especially for female academic staff; by a lack of adequate resources; to the research nature of departments, including the quality of research; to the position of anatomy in the biomedical sciences; and from pressures to retreat from a dissection-based education. In tracing a future trajectory for anatomy, issues outlined are the inevitability of change, the need for anatomy to market itself to the world, and the opportunities presented for anatomy to view itself increasingly as a contributor to broad scholastic endeavors. Suggestions include exploring the possibilities presented by virtual anatomy museums, the use of online learning to reach those not normally in touch with anatomy teaching, and exploring the integrated courses with humanities disciplines. It is concluded that anatomy will flourish if there is a willingness to expand the traditional horizons and be prepared to integrate all that is best in the person-to-person and digital worlds. 相似文献

在当今世界人类交往更趋频繁的崭新形势下 ,全球史观已成为不可逆转的时代趋向。远古至 15 0 0年的世界史 ,需要从体系和内容两方面予以更新 ,从纵横交叉的宏观角度加以重构。其一 ,以文明为基本研究单位 ,使用比较史学方法 ,正确判定人类各大区城性文明的历史地位 ,并正确处理它们各自在通史中所占的份量和比例 ,选取史料也应以对区域性文明的影响为标准。其二 ,正确处理农耕和游牧两大地带的相互关系 ,充分认识它们的交往对人类文明发展的全局性影响 相似文献

It is known that striking rodent prey induces a sustained, high rate of tongue flicking in rattlesnakes. The present study shows this phenomenon (called strike-induced chemosensory searching, SICS) to occur in species of rattlesnakes not previously investigated and in two species ofAgkistrodon. SICS occurs in Old World vipers (Eristocophis, Vipera, Bitis), including species which normally hold their prey after striking. A hypothesis is offered which (1) accounts for the occurrence of SICS in these latter species and (2) suggests that SICS in some viperids may have arisen through paedomorphic evolution. More generally, it is concluded that SICS is probably a homologous trait in vipers and pit vipers and that the trait may have first appeared in elapid ancestors of the viperidae. 相似文献

Technology stems from science. Science represents important and specific values in the whole of human culture. The history of scientific and philosophical ideas is an exciting and thrilling story with an open end. Such topics can contribute to educating the whole and balanced engineer. 相似文献
