Turn of Fortune in Psychoanalysis: The 1924 Rank Debates and the Origins of Hermeneutic Psychoanalysis

The history of psychoanalysis can be characterized by conflicts that besides their personal content meant a closure and an opening in the development of the theorecial and practical (self )understanding of the discipline. The 1923-24 conflict that resulted in the separation of Rank from the movement and showed the first signs of uneasiness against the mainstream of psychoanalysis in Ferenczi's approach is relatively less known. However, its theoretical, or more general: discoursive impact on psychoanalysis was enormous.The debate took place among the top leaders of the movement, Rank and Ferenczi on one side, Jones, Abraham, Sachs on the other. In the center of the discussion there were two books, The Trauma of Birth by Rank and the The Development of Psychoanalysis by Ferenczi and Rank. With the help of documents I try to show that Freud first supported his Vienna-Budapest friends, later changed over to the other camp. As a general effect, I suggest that this debate resulted in the withdrawal from the earlier more hermeneutic-dialogical, therapy centered psychoanalysis toward a medical, objective, systematic and metapsychology oriented discipline. Besides the general theoretical change the power centers of psychoanalysis shifted toward West, Vienna and Budapest was substituted first by Berlin, later by London and New York.     

Density evolution during the growth of disc-shaped aluminium nanoparticles on a liquid surface

Aluminium (Al) nanoparticles (NPs) have been successfully fabricated on a liquid surface by thermal evaporation at room temperature. The Al NPs exhibit a disc-shaped morphology with mean diameter and height in the ranges 20–35 and 1.3–3.7?nm, respectively. As the nominal film thickness increases from 0.02 to 0.18?nm, the mean diameter and height are nearly independent of the thickness, implying that the density of the NPs increases during their growth. An explanation for this phenomenon is presented.     

精神障碍患者非自愿住院医疗法律规制之原则

基于对社会权利秩序的维护和对精神障碍患者个体权利的恢复,非自愿住院医疗有存在的必要性,但又涉及到对自由权的剥夺,衡平其中的矛盾在于对非自愿住院医疗进行正当的法律规制,探讨了精神障碍患者非自愿住院医疗法律规制应当遵循的法定原则、法律价值权衡原则、最小限制原则、比例原则、医疗目的原则和司法审查原则.     

An individual's work values in career development

This study examined the mediation effect of career decision self‐efficacy in relation to work values and career decision status. The authors surveyed 308 college students about their own intrinsic (e.g., helping others) and extrinsic (e.g., high income) work values and those of significant others, career decision self‐efficacy, and career decision status. The results indicated that the intrinsic and extrinsic work values of significant others were related to the intrinsic and extrinsic work values of the self and that intrinsic work values were more adaptive than extrinsic work values in career development.     

奖励影响注意选择的认知加工机制

奖励不仅能够塑造行为, 也能影响个体的内部心理过程。在注意选择过程中, 与奖励联结的刺激能够吸引注意资源。当目标刺激与奖励联结时, 能够易化注意选择过程; 当分心刺激与奖励联结时, 能够阻碍注意选择过程。可见, 奖励从不同角度对注意选择产生影响。奖励对注意选择的影响可能有其特有的认知机制, 并且奖励对注意的捕获效应受到许多因素的调节, 如奖励预测、工作记忆容量、人格特质及刺激的新异性。未来的研究应该尝试将奖励影响注意选择的研究成果应用于不良注意偏向临床干预的实践领域。     

单侧化准备电位启始时间点的测算:刀切法*

刀切法是统计学家Quenouille提出的一种参数估计方法,由Miller等在1998年首次将刀切法应用在单侧化准备电位(LRP)启始时间点(onset)的测量中。相对于以往单个被试法而言,它是较新的一种统计方法。本文综述了刀切法的统计原理和基本使用过程,并和单个被试法进行了差异比较,最后对这一方法的发展趋势做了展望。     

Testing take-the-best in new and changing environments

Take-the-best is a decision-making strategy that chooses between alternatives, by searching the cues representing the alternatives in order of cue validity, and choosing the alternative with the first discriminating cue. Theoretical support for take-the-best comes from the “fast and frugal” approach to modeling cognition, which assumes decision-making strategies need to be fast to cope with a competitive world, and be simple to be robust to uncertainty and environmental change. We contribute to the empirical evaluation of take-the-best in two ways. First, we generate four new environments—involving bridge lengths, hamburger prices, theme park attendances, and US university rankings—supplementing the relatively limited number of naturally cue-based environments previously considered. We find that take-the-best is as accurate as rival decision strategies that use all of the available cues. Secondly, we develop 19 new data sets characterizing the change in cities and their populations in four countries. We find that take-the-best maintains its accuracy and limited search as the environments change, even if cue validities learned in one environment are used to make decisions in another. Once again, we find that take-the-best is as accurate as rival strategies that use all of the cues. We conclude that these new evaluations support the theoretical claims of the accuracy, frugality, and robustness for take-the-best, and that the new data sets provide a valuable resource for the more general study of the relationship between effective decision-making strategies and the environments in which they operate.
