本教糌粑面塑文化略论

本教是藏族的本土宗教,其宗教礼仪的多样性与内容的丰富性无意中为后人保留了丰富的远古信息。糌粑面塑作为本教礼仪的一个重要组成部分,通过对它的研究不仅能够揭示本教教理的深刻意蕴,同时,还可以对与其相关的一系列问题进行互证、互识、互补。     

Delayed backward conditioning of place preference induced by wheel running in rats

Backward conditioning of place preference has been obtained in hungry rats when wheel running (the rewarding US) is followed immediately by exposure to a distinctive chamber (the CS). We tested whether such backward conditioning would occur with a 10-min delay. In each of four paired exposures, a period of wheel running (2 or 22 h, in separate experiments) was followed by 10 min in the home cage and then 30 min in the CS chamber. Control rats were put in the CS chamber without wheel running. In other similar experiments, a 0-, 10-, or 30-min delay separated wheel running from exposure to the CS chamber. Reliable conditioned place preference (CPP) occurred when the delay was 0 or 10 but not 30 min. The strength of CPP decreased as the delay increased. These findings imply that the reward process initiated by wheel running remains active for some time after running stops. They support the view that the suppression of feeding produced by wheel running in hungry rats (activity anorexia) is mediated by this reward process.

5~6岁自闭症儿童与正常儿童的辨别反转学习研究

采用条件性辨别反转范式,考察自闭症儿童与正常儿童的反转灵活性。44名5~6岁儿童（24名自闭症儿童,20名正常儿童）参加了辨别反转学习。结果显示：⑴在习得阶段,两类儿童都能辨别两个不同的条件性刺激;⑵在晚期反转阶段,正常儿童在晚期反转阶段升高了对新的条件性厌恶刺激的主观预期值,辨别了新的条件性刺激,而自闭症儿童在晚期反转阶段对新的条件性厌恶刺激的主观预期值没有显著性变化,无法辨别新的条件性刺激。研究结果表明,5~6岁自闭症儿童反转灵活性存在缺陷。     

实体和初级关系（FOR）匹配的分离与结合对故事类比通达的影响

采用移动窗口阅读技术深入探讨实体和初级关系（FOR）匹配的分离与结合对故事类比通达的影响,对表面特征和结构特征在类比通达中的作用进行检验。实验1探讨系统变化目标故事和线索故事之间实体匹配数目与实体和初级关系（FOR）匹配的分离与结合是否影响读线索故事时对目标故事的回想。实验2探讨系统变化目标故事和线索故事之间初级关系（FOR）匹配的数目与实体和初级关系（FOR）匹配的分离与结合是否影响读线索故事时对目标故事的回想。实验3探讨实体和初级关系（FOR）匹配的分离与结合对目标故事的通达是否与高级关系（HOR）的匹配有关。结果表明,实体匹配独立影响通达,实体和初级关系（FOR）分离与结合影响故事类比通达,高级的结构关系（HOR）是实体和初级关系（FOR）影响故事类比通达的必要条件。

Love's labor in the health care system: working toward gender equity

In this commentary on Eva Feder Kittay's Love's Labor: Essays on Women, Equality, and Dependency, I focus on Kittay's dependency theory. I apply this theory to an analysis of women's inadequate access to high-quality, cost-effective healthcare. I conclude that while quandaries remain unresolved, including getting men to do their share of dependency work, Kittay's book is an important and original contribution to feminist healthcare ethics and the development of a normative feminist ethic of care.     

Out-of-body experiences: from Penfield to present

Can the brain, when stimulated, yield entirely novel experiences? Blanke et al. (2002) describe a patient who reported spontaneous out-of-body experiences during electrical stimulation of her angular gyrus. These findings, although apparently extraordinary, agree with much earlier reports from a patient tested by Wilder Penfield. Such studies can provide clues about the nature of conscious experience.     

语音告警信号语速研究

用普通会话句表和飞机告警句表两种测试材料 ,以言语可懂度测试法和主观评价法研究言语告警信号的适宜语速。实验中的语速定为 0 .1 1、0 .1 5、0 .2 0、0 .2 5、0 .3 5和 0 .45秒 /字六级。实验模拟飞机座舱环境 ,采用计算机生成的数字化言语信号 ,在 90 d B(A)的飞机噪声环境下 ,通过耳机传递给被试。研究得到以下结论 :言语告警信号的适宜语速为 0 .2 5秒 /字 (或 4字 /秒 ) ,它的下限为 >0 .2 0秒 /字 (或 <5字 /秒 ) ,它的上限为 0 .3 0秒 /字 (或 3 .3 3字 /秒 )。
