S+ versus S− Fading in prompting procedures with autistic children

The purpose of this investigation was to assess the relative effectiveness of two prompt-fading procedures for teaching difficult visual discriminations to autistic children. Both prompt procedures involved within-stimulus fading where manipulation occurred on the relevant component of the discrimination. One procedure involved fading first along the S+ stimulus, while holding the S? stimulus constant. The other procedure involved fading first along the S? stimulus, while holding the S+ stimulus constant. Eight autistic children were each taught two discriminations, one by each of the prompt procedures. Results indicated that for all but one child, the discriminations were acquired significantly faster, with fewer errors, when the S+ stimulus was faded first. These findings are related to the literature on the effects of stimulus novelty on selection and learning.     

Stability of nonverbal immediacy behaviors

The stability of the immediacy behaviors of approach distance, eye contact, approach orientation, and body lean was examined across two interviews over a 25 min and a 1-week interval. Stability coefficients were similarly high between the sessions for each interval. General support was found for the presence of compensatory relationships between approach distance and eye contact and between approach distance and approach orientation. A bimodal distribution of approach distances, found in both studies, included a substantial intermediate range which was not used by any of the subjects. Evidence from personality data and self-ratings suggested that subjects who remained more distant were more anxious than those who approached closer.     

发散性思维的年龄差异及“位置法”记忆训练的作用

该研究的目的是探讨发散性思维的年龄差异以及“位置法”记忆训练对发散性思维的迁移作用。训练组为经过记忆训练的青年人24名,老年组20名,对照组为相匹配的青年人24名、老年人19名。结果表明:(1)在图形、符号、语义三方面的流畅性、变通性和独特性上,老年组均很显著地比青年组差。青年组的个别差异较大,老年组的更大,尤其是独特性。(2)青年训练组的图形流畅性、独特性及语义的独特性成绩显著优于其对照组,老年训练组图形的变通性有优于其对照组的趋势(P=.052),说明“位置法”记忆训练对发散性思维有一定的间接迁移作用,尤其是对青年人。(3)发散性思维与想象力、数字符号、训练前和训练后词的记忆以及图形的记忆成绩均有很显著正相关。而词汇成绩只与训练组两项发散性思维有显著相关。     

旧客体抑制和新客体捕获视角下预览效应的机制

预览效应是一种在已经存在的多个旧客体中优先选择多个新客体, 对新客体表现出优先加工的现象。文章综述了预览效应认知神经机制的两种主要观点：(1)旧客体抑制观点, 认为预览效应是由于对旧客体的抑制; (2)新客体突现捕获注意观点, 认为预览效应是由于新客体出现伴随着亮度突然增加捕获注意。这两种观点之间的主要争论在于：预览效应与新旧客体亮度变化的关系; 新旧客体的颜色关系是否影响对目标的搜索; 在一些因素的作用下, 旧客体形状变化是否还会破坏预览效应。文章指出, 预览效应是旧客体抑制机制与新客体突现捕获注意机制共同作用的结果。     

医药代表问题及其法律规制

近年我国医药行业不断发展,其营销人员的数量也在膨胀,从而引发了药品购销中的一系列问题,而医药代表在其中扮演着重要角色。由此,“医药代表问题”已引起人们的反感;国家和医院也采取不少措施打击,但收效甚微。医药代表问题成为社会热点。分析医药代表问题的社会成因,提出法律规制,旨在促进这一行业健康发展。     

Inferential reasoning by exclusion in pigeons, dogs, and humans

The ability to reason by exclusion (which is defined as the selection of the correct alternative by logically excluding other potential alternatives; Call in Anim Cogn 9:393–403 2006) is well established in humans. Several studies have found it to be present in some nonhuman species as well, whereas it seems to be somewhat limited or even absent in others. As inconsistent methodology might have contributed to the revealed inter-species differences, we examined reasoning by exclusion in pigeons (n = 6), dogs (n = 6), students (n = 6), and children (n = 8) under almost equal experimental conditions. After being trained in a computer-controlled two-choice procedure to discriminate between four positive (S+) and four negative (S−) photographs, the subjects were tested with displays consisting of one S− and one of four novel stimuli (S′). One pigeon, half of the dogs and almost all humans preferred S′ over S−, thereby choosing either by novelty, or by avoiding S− without acquiring any knowledge about S′, or by inferring positive class membership of S′ by excluding S−. To decide among these strategies the subjects that showed a preference for S′ were then tested with displays consisting of one of the S′ and one of four novel stimuli (S′′). Although the pigeon preferentially chose the S′′ and by novelty, dogs and humans maintained their preference for S′, thereby showing evidence of reasoning by exclusion. Taken together, the results of the present study suggest that none of the pigeons, but half of the dogs and almost all humans inferred positive class membership of S′ by logically excluding S−.

帛书《易传》四篇天人道德观析论

本文通过对帛书易传<二三子问>、<易之义>、<要>、<缪和、昭力>四篇的分析,认为帛传四篇为孔子<易>论,其中包涵着<论语>、<孔子集语>、传世本<易传>等反映孔子思想的传世文献所隐微罕见的天人道德观念;帛传四篇表现了孔子在涵括三代以至春秋新旧天人观念的基础上对于天人内涵的初步的哲学改造,反映了孔子将传统的主宰之天转化为道德之天、并将传统的主体对于形上存在的外在超越关系转化为内在超越关系的致思取向,从而凸显了孔子作为当时敏锐而深邃的思想家的形象;帛传四篇所涵具的孔子天人道德思想补足了三代天命德政观与思孟天道性命思想之间的逻辑缺环,是经由曾子(<天圆>)而达致<中庸>、郭店儒家简、<孟子>乃至传世本<易传>所体现的天道性命思想高峰的理论根据.     

《易传》的天人合一哲学及其对中国封建法的影响

<易传>通过吸取道家的天道观、承袭儒家的伦理观,利用阴阳家的阴阳学说,建构了兼具自然主义和人文主义色彩的天人合一哲学,完成了该哲学的世俗化历程.本文从本体论、认识论、方法论角度探讨了该哲学的基本理论,指出,<易传>天人合一哲学的基本精神是道德伦理哲学.它对中国封建法的思维模式和价值取向产生了深远的影响.
