玻璃体手术技术与玻璃体替代物平稳发展的期待

随着玻璃体手术技术日趋成熟,玻璃体替代物的问题逐渐显现出来,两者之间的矛盾就是科学技术发展不平衡的表现.一方面,我们用先进玻璃体切除技术治疗眼病,不断扩充手术的适应症,另一方面,却没有理想的玻璃体替代物,影响着手术的效果.提出了我们面对的挑战和亟待解决的问题,以及应采取的态度.     

Homosexuality: Coming out of the confusion

The author asserts that earlier theoretical assumptions contribute to the conceptual confusion about homosexuality in much contemporary psychoanalytic research. Bergeret's article, recently published in this Journal , is exemplary of this confusion. The author refutes his contention that homosexuality is not 'true' sexuality but merely a defensive, narcissistic fixation away from, or a nearly psychotic denial of, heterosexuality. He then clarifies specific areas of conceptual confusion regarding homosexuality still prevalent in psychoanalytic discourse that derive from earlier theoretical premises. These areas of confusion include manifest versus latent homosexuality, narcissism and bisexuality, oedipal dynamics and development, and transference and technique.     

Reflections on Klein's radical notion of phantasy and its implications for analytic practice

Analysts may incorporate many of Melanie Klein's important contributions (e.g., on preoedipal dynamics, envy, and projective identification) without transforming their basic analytic approach. In this paper I argue that adopting the Kleinian notion of unconscious phantasy is transformative. While it is grounded in Freud's thinking and draws out something essential to his work, this notion of phantasy introduces a radical change that defines Kleinian thinking and practice and significantly impacts the analyst's basic clinical approach. This impact and its technical implications in the analytic situation are illustrated and discussed.     

Freedom – the abyssal ground of Freudian psychoanalysis

Freedom is an a priori condition for the way in which Freudian psychoanalysis thematizes the development, the structure and the dynamics of our psychic life; the human psyche is essentially constituted by freedom. What this really means is that psychoanalysis lacks a foundation or ground – both as a psychological science and as a kind of clinical treatment. Freedom is the abyssal ground of psychoanalysis.     

拖延的认知神经机制与基因:行为-脑-基因的多角度研究

拖延是一种普遍存在,具有跨时间和跨情景稳定性的问题行为,严重的拖延甚至会危害到人们的工作、学习及身心健康。鉴于目前对于拖延的认知神经机制仍不清楚,研究模态较为单一,本研究拟从行为-脑-基因的系统研究思路出发,以多模态MRI(Task、Resting、VBM和DTI)为主要技术手段,将HTR2B基因多态性作为突破口,系统考察拖延的认知机制、神经基础和遗传基础,并试图制定拖延的应对与干预方案。研究分为4个部分:(1)从行为上,结合预期恐惧范式和跨期选择范式探索其拖延决策的机制;(2)在神经层面上,采用MRI多模态技术系统考察拖延行为的神经基础;(3)在基因层面上,采用分子遗传学方法,将HTR2B设定为靶基因以深入研究拖延的遗传基础,并考察脑结构和脑功能在基因与行为间的中介作用;(4)最后从行为干预与脑的可塑性的角度,设计拖延的干预方法来改善拖延行为并验证拖延的神经机制。     

Developmental grey matter changes in superior parietal cortex accompany improved transitive reasoning

The neural basis of developmental changes in transitive reasoning in parietal regions was examined, using voxel-based morphometry. Young adolescents and adults performed a transitive reasoning task, subsequent to undergoing anatomical magnetic resonance imaging (MRI) brain scans. Behaviorally, adults reasoned more accurately than did the young adolescents. Neural results showed (i) less grey matter density in superior parietal cortex in the adults than in the young adolescents, possibly due to a developmental period of synaptic pruning; (ii) improved performance in the reasoning task was negatively correlated with grey matter density in superior parietal cortex in the adolescents, but not in the adult group; and (iii) the latter results were driven by the more difficult trials, requiring greater spatial manipulation. Taken together, the results support the idea that during development, regions in superior parietal cortex are fine-tuned, to support more robust spatial manipulation, resulting in greater accuracy and efficiency in transitive reasoning.     

Development and test of a model of interdisciplinary competencies

Interdisciplinary work offers both innovative potential and challenges in collaboration. The present paper summarizes three studies intended to foster a psychological, competency-focused understanding of interdisciplinary work. In a qualitative interview study (Study 1) with expert practitioners of interdisciplinarity, we used the critical incident technique to explore which individual competencies support interdisciplinary collaborations and improve innovative outcomes. Focusing on competencies specific to interdisciplinarity, we derived a four-dimensional model. In Study 2, we tested the model dimensions (1) initiative for exchange, (2) target group-specific communication, (3) knowledge integration, and (4) reflection in a quantitative survey study among N = 315 employees who were experienced in interdisciplinary work using exploratory structural equation modelling. Finally, in Study 3, we studied the convergent and divergent validity of interdisciplinary competencies as well as their role in predicting team outcomes. Here, a dyadic sample of N = 448 target persons and N = 153 interdisciplinary colleagues were surveyed. We discuss possible applications for the new model of interdisciplinary competencies and the developed self-report instrument.     

Two Systems of Self-Regulation and the Differential Application of Psychoanalytic Technique

Out of our work over the years on child development, clinical technique, and sadomasochism, we have begun to formulate a model of development that describes two possible ways of responding to feelings of helplessness in the face of the challenges of internal and external experience. Any psychoanalytic model has implications for how we think about technique and can be tested on the basis of its utility in generating technical ideas and enhancing our therapeutic repertoire. At this juncture in the history of our field, it is crucial for us to demonstrate that psychoanalytic techniques are effective in helping people enter treatment, change, and finish in a way that consolidates their gains. In this paper we explore the utility of our two-systems model for expanding the discourse about psychoanalytic technique.
