Nodal structure and the partitioning of equivalence classes

By definition, all of the stimuli in an equivalence class have to be functionally interchangeable with each other. The present experiment, however, demonstrated that this was not the case when using post-class-formation dual-option response transfer tests. With college students, two 4-node 6-member equivalence classes with nodal structures of A-->B-->C-->D-->E-->F were produced by training AB, BC, CD, DE, and EF. Then, unique responses were trained to the C and D stimuli in each class. The responses trained to C generalized to B and A, while the responses trained to D generalized to E and F. Thus, each 4-node 6-member equivalence class was bifurcated into two 3-member functional classes: A-->B-->C and D-->E-->F, with class membership precisely predicted by nodal structure. A final emergent relations test documented the intactness of the underlying 4-node 6-member equivalence classes. The coexistence of the interchangeability of stimuli in an equivalence class and the bifurcation of such a class in terms of nodal structure was explained in the following manner. The conditional discriminations that are used to establish a class also imposes a nodal structure on the stimuli in the class. Thus, the stimuli in the class acquire two sets of relational properties. If the format of a test trial allows only one response option per class, responding on those trials will be in accordance with class membership and will not express the effects of nodal distance. If the format of a test trial allows more than one response option per class, responding on those trials will be determined by the nodal structure of the class. Thus, the relational properties expressed by the stimuli in an equivalence class are determined by the discriminative function served by the format of a test trial.     

汉末思想嬗变对《伤寒杂病论》的影响

汉末是两汉经学向魏晋玄学过渡的时期,有清通简要、得意忘言、务实求真等时代特点,并在一定程度上摆脱了神仙之风对医学的影响。从思想嬗变的角度,对中医巨著《伤寒杂病论》的行文风格、方法原则、学术思想等诸方面进行分析,从而提出对其时代背景研究的新思路。     

古埃及疾病医治理念透析

疾病医治理念是古埃及文明的重要组成部分。古埃及人针对不同类别疾病有着相应的医治理念：药物、魔法与意志是内科疾病的医治理念;河渠原理是医治外科疾病的理念;对于治疗心理疾病主要是寻求神灵的拯救;预防疾病的理念是保持圣洁。挖掘、梳理这些医治理念,可以加强医学史的学科建设,对某些疾病的治疗有参考价值。

"It's Us Against the World": How Distrust in Americans versus People-In-General Shapes Competitive Foreign Policy Preferences

Previous research has uncovered links between generalized distrust and preferences for competitive (vs. cooperative) action. However, based on individuals' tendency to hold consistent attitudes and to believe that their own political preferences are morally legitimate, it was hypothesized that the direction of the relationship between distrust and competitive foreign policy preferences would depend on which category individuals had in mind: Americans or people. Two correlational studies with American participants were consistent with this hypothesis. Study 1 showed that distrust in Americans versus people had qualitatively different relationships with support for competitive policy preferences (i.e., immigration control, militaristic action). Study 2 found that when the covariance between distrust in Americans and people was controlled, distrust in Americans predicted opposition to torture of suspected terrorists, whereas distrust in people predicted support for torture of suspected terrorists. Moreover, individual discrepancies between distrust in Americans versus people uniquely predicted support for torture. Finally, mediational analyses in both studies indicated that political conservatism explained the effects between distrust in Americans versus people and competitive policy preferences. It is argued that distrust in Americans and distrust in people are distinct but complementary bases of Americans' moral-political reasoning.     

对大学生心理健康教育几个误区的思考

针对大学生心理健康教育中,在心理健康水平的评估、心理健康教育的内容与形式、心理咨询和心理档案的建立等四个方面可能出现的误区,提出了合理化的建议.认为当代大学生心理健康水平总体是较高的,心理健康教育应内容活泼、形式生动、具有针对性;心理咨询应有利于学生隐私的保护;心理健康档案不宜机械使用,应动态追踪.

类别不确定下的特征推理是基于类别还是基于特征联结

共有3个实验探讨归类不确定情况下的特征推理是基于类别进行还是基于特征联结进行。实验1在中文条件下重复了Verde等人2005的实验,得出了与之相符的结果,这个结果用基于类别的理性模型的设想或者是用基于特征联结的设想都可以解释。实验2考察被试在靶类别的类别特征频次并且特征结合出现频次高低不同的条件下特征推理的情况,实验2的结果表明,高集中与低集中两种条件下特征推理没有显著差异,不符合特征推理是基于类别进行的设想,而与特征推理是基于特征联结进行的设想吻合。实验3进一步考察被试在特征结合出现的总频次并且靶类别中特征结合出现的总频次高低不同的条件下特征推理的情况,结果表明,在高结合条件下进行特征推理要优于在低结合条件,支持了在归类不确定情况下的特征推理是基于特征联结进行的设想。据此可以认为,人们的特征推理是基于特征之间联结的频次进行,而不是基于类别进行     

《管子》国土资源管理哲学思想初探

《管子》是我国古代百科全书式的管理哲学巨作。本文试图从土地的分配、土地的开发、国土的规划、资源的保护等四个方面来探讨《管子》的国土资源管理哲学思想。《管子》国土资源管理哲学思想的基本原则,对今天的国土资源管理理论的建设和方针政策的制定仍具有一定的借鉴意义和参考价值。     

晚清管子研究述论

晚清以降。诸子学走向复兴。作为其中重要一支,《管子》一书也摆脱以往“德主刑辅”、“以子证经、史”的边缘地位,受到广大士人、学者的关注。大致而言,晚清的管子研究经历了“通子致用”、“援西释管”和“改塑管子”三个阶段,逐渐完成了由古典向近代的学术嬗变。
