Certain Effects of Mescaline and Lysergic Acid on Psychological Functions

An experiment was performed to determine whether or not changes in field dependence could be obtained under laboratory-produced stress conditions: i.e., body rotation. Two treatments and one control group were employed. Subjects in the first group were given the Rod and Frame Test; and, after a delay, they were spun and retested immediately after rotation (immediate-test group). Subjects in another group were given the Rod and Frame Test, were rotated ; and given the Rod and Frame Test after a delay of 10 minutes (delay-test group). Subjects in the control group were given the Rod and Frame Test and then given the Rod and Frame Test after a 15-minute delay. Subjects in both the immediate-test group and control group showed a decrease in field dependence, with the immediate-test group showing a slightly greater decrease than did the control group. Subjects in the delay-test group did not show a decrease in field dependence. Contrary to expectation, in no case was there a mean increase in field dependence. The results indicate the possibility of a normal decrease in field dependence with readministration of the Rod and Frame Test after a short lapse of time.     

Behavioral Skills Training With Teachers: Booster Training for Improved Maintenance

Behavioral skills training (BST) has been employed within many different populations for the reduction of problem behaviors and acquisition of new skills; however, these changes have not always maintained over time. This study evaluated the effects of a booster training for re-establishing the classroom management proficiencies that teachers had acquired previously, but had declined over a 12-month period. The single-subject experimental results showed the booster training to be effective in re-establishing teacher performance of skills as measured by both analogue role-play and in situ postassessments within the classroom. These findings suggest that a booster training utilizing BST may be an important strategy for maintaining skill performance over time.     

Transpersonal Psychology: Defining the Past,Divining the Future

Retrospective analysis of definitions published over some 35 years suggests the major subject areas of the field can be summed up in three themes: beyond-ego psychology, integrative/holistic psychology, and psychology of transformation. Theme frequency analysis reveals that early emphasis on alternative states of consciousness has moderated into a broader approach to human transcendence, wholeness, and transformation. This expanded definition of transpersonal psychology suggests the field has much in common with integral psychology. As a comprehensive, historically based content summary, this tripartite definition contributes a small but vital piece to the foundation of a transpersonal vision that is spreading across the globe. While transpersonal psychology still needs to embody the inclusiveness and diversity that it represents, its vision is one of great relevance to the contemporary human condition.     

伤害回避的脑机制及其生物基础

伤害回避是指个体对厌恶刺激信号做出强烈的反应,并学会被动地回避惩罚的一种倾向,这一倾向使得个体反复思考未来的结局,并谨慎小心地对待不确定情景中的事件,进而更有可能诱发情感障碍。伤害回避涉及的神经网络包括三个子网络,即额顶叶-前扣带皮层的连接、皮层-杏仁核的连接和白质通道的结构性连接,这三个子网络分别与羞怯感-易疲劳性、预期担心以及不确定环境中的害怕情绪有关。而其生物基础则包括单一基因多态性和基因多态间的交互作用。今后的研究应该集中在深化伤害回避神经网络与生物基础间的联合机制、研究三种及以上基因多态间的交互作用、考察其他因素对基因效应的调节作用、注重伤害回避四种亚型相关神经网络之间的连接、探讨5-HT4等其他几种5-羟色胺受体多态性与伤害回避的关系以及分析伤害回避内部机制在抗抑郁治疗中的作用等方面。     

提取练习在记忆保持与迁移中的优势效应：基于认知负荷理论的解释

提取练习比建构概念图更有利于记忆保持和迁移的研究结果尚存在争议。依据认知负荷的3个成分,设计两个实验探究前期知识水平与策略复杂性对以上两种学习策略有效性的影响。结果表明：(1)前期知识水平的主效应不显著,但是与学习策略之间存在交互作用：在提取练习策略条件下,高前期知识水平的被试与低前期知识水平的被试在记忆保持和迁移上的正确率没有显著差异,但是在建构概念图策略条件下,高前期知识水平的被试在记忆保持和迁移上的正确率显著地高于低前期知识水平的被试;(2)当降低概念图的难度后,被试使用建构部分概念图策略产生的认知负荷与使用提取练习策略相比显著降低,并且其在学习阶段学习到的知识量显著地高于使用提取练习策略的结果,但是在最终测试上,其记忆保持与迁移的正确率与使用提取练习策略并没有显著差异,策略的复杂性增加了学习者的额外负荷,但是对策略有效性的发挥却不具有决定性影响。以上结果说明提取练习策略之所以比建构概念图策略更具优势,不是因为其策略本身更易掌握,而是因为其与建构概念图策略相比不受学习者前期知识水平的影响。这意味着认知负荷理论可以很好地解释提取练习在记忆保持与迁移中产生优势效应的内部机制,并进一步证实提取练习与精细编码不同,具有独特的加工机制。     

支持型领导行为在工作压力模型中的作用机制研究

本研究调查了 1 3个企业共 2 1 8位员工 ,探讨了支持型领导行为在角色冲突、人际冲突、缺乏成就与发展 (压力源 )和工作满意感、工作焦虑 (压力反应 )之间的作用机制。研究发现 :(1 )支持型领导行为对工作满意感和工作焦虑有主效应 ,但是由于逆向缓冲的存在 ,支持型领导行为的主效应并不总是对的 ,我们必须在更大的范围中考虑领导行为的效应 ;(2 )缓冲效应的六个假设只有一个被证明 ,但是方向相反 ,即支持型领导行为加剧了由人际冲突造成的工作不满意感 ;(3)两个中介模型的部分关系被证明 ,但是我们很难确定是支持型领导行为的弱化效应还是评价作用。为了更好地说明因果关系 ,在将来的研究中纵向研究设计被认为更为恰当。
