拖延原因的精神分析探索

拖延行为在日常生活中非常普遍,给人们的学习、生活带来不利影响。本文阐述了拖延的概念和性质,结合精神分析理论,从冲突、焦虑、防御机制和本能等几个方面对消极拖延行为进行分析,旨在为拖延行为的干预提供借鉴。     

一例人际关系敏感的心理咨询案例报告

一位女大学生在由于人际关系敏感,不能与同学正常交往,出现焦虑情绪、睡眠障碍、学习效率下降等症状。咨询师通过摄入性会谈收集了资料,发现来访者之所以陷入困境与复杂的家庭关系有关。咨询师主要运用认知行为疗法,帮助来访者进行认知重建,通过5次咨询,来访者情绪趋于平稳,睡眠得到了改善,学习效率得以提高,社会适应能力及心理承受能力都得到了提高,人格进一步完善。     

对老年性痴呆治疗研究的反思

随着世界人口逐年老化,老年性痴呆已成为全球性的社会一医学问题。神经科学及相关学科领域的内的工作者正积极地投入到对Ａｌｚｈｅｉｍｅｒ病各方面的深入研究,在预防和治疗方面的探索已取得一些阶段性的成果。然而,由于相关基础研究尚无关键性突破,临床治疗始终缺乏有效手段。     

Conformational properties of serum albumin binding sites in rats with different behaviour in the open field test

In this study, the hypothesis was tested that behaviour of rats under the open field test condition and effects of subsequent acute stress relate to conformational properties of the main plasma carrier protein, albumin.To evaluate albumin properties, fluorescence intensity of a molecular probe CAPIDAN (N-carboxyphenylimide of dimethylaminonaphthalic acid) at N (at pH 7.4) and F (at pH 4.2) albumin conformations was measured and the N-F signal ratio was calculated. The data obtained showed that CAPIDAN fluoresces selectively from albumin in rat serum and its fluorescence is sensitive to binding of fatty acids and some other ligands to albumin. Behaviour of 78 Wistar male rats was characterized from the fraction of time taken for exploratory and ambulatory activity during the open field test. In rats not subjected to stress (n = 40), a negative correlation was revealed between open field activity and CAPIDAN N-to-F ratio for albumin (r = - 0.55, p < 0.0005). In the group of rats subjected to acute stress (immobilization plus stochastic electrocutaneous stimulation) the correlation between behavioural activity and the albumin conformational properties was significantly positive (r = 0.59, p < 0.0001): the CAPIDAN albumin fluorescence ratio increased in the highly active rats and decreased in the low-activity rats. The mechanisms of the observed effects may involve differences in nonesterified fatty acid production during stress.     

君主与基督教--关于《君主论》与《论基督君主的教育》的比较研究

在对晚期文艺复兴不同潮流、不同著作地分析中,我们看到一种新的,围绕于君主与基督教的核心历史关系重新解读历史的可能性途径,看到文艺复兴核心概念群的不同组织方式.从而,文艺复兴以一种与"近代起源"拉开了差距的面目呈现出来,它意味着重写历史,尤其是概念史的必要性.     

Exploration in outbred mice covaries with general learning abilities irrespective of stress reactivity, emotionality, and physical attributes

Across multiple learning tasks (that place different sensory, motor, and information processing demands on the animals), we have found that the performance of mice is commonly regulated by a single factor ("general learning") that accounts for 30-40% of the variance across individuals and tasks. Furthermore, individuals' general learning abilities were highly correlated with their propensity to engage in exploration in an open field, a behavior that is potentially stress-inducing. This relationship between exploration in the open field and general learning abilities suggests the possibility that variations in stress sensitivity/responsivity or related emotional responses might directly influence individuals' general learning abilities. Here, the relationship of sensory/motor skills and stress sensitivity/emotionality to animals' general learning abilities were assessed. Outbred (CD-1) mice were tested in a battery of six learning tasks as well as 21 tests of exploratory behavior, sensory/motor function and fitness, emotionality, and stress reactivity. The performances of individual mice were correlated across six learning tasks, and the performance measures of all learning tasks loaded heavily on a single factor (principal component analysis), accounting for 32% of the variability between animals and tasks. Open field exploration and seven additional exploratory behaviors (including those exhibited in an elevated plus maze) also loaded heavily on this same factor, although general activity, sensory/motor responses, physical characteristics, and direct measures of fear did not. In a separate experiment, serum corticosterone levels of mice were elevated in response to a mild environmental stressor (confinement on an elevated platform). Stress-induced corticosterone levels were correlated with behavioral fear responses, but were unsystematically related to individuals' propensity for exploration. In total, these results suggest that although general learning abilities are strongly related to individuals' propensity for exploration, this relationship is not attributable to variations in sensory/motor function or the individuals' physiological or behavioral sensitivity to conditions that promote stress or fear.     

Organizational partnerships in China: self-interest, goal interdependence, and opportunism

Opportunism in organizational partnerships may be understood in terms of how partners conclude that their self-interests are related to each other. When partners believe that their goals are competitively but not cooperatively related, they are tempted to pursue their self-interests opportunistically. Cognitive understandings and values of a shared vision may help partners believe their goals are cooperatively related. Results from 103 pairs of customer and supplier organizations support the argument that partnerships are not inevitably threatened by opportunism. Using structural equation analysis, the authors suggested that shared vision can help partners develop cooperative goals that lead to low levels of opportunism. These results suggest that a shared vision and cooperative goals are important foundations for effective organizational partnerships.     

The role of embodied intention in early lexical acquisition

We examine the influence of inferring interlocutors' referential intentions from their body movements at the early stage of lexical acquisition. By testing human participants and comparing their performances in different learning conditions, we find that those embodied intentions facilitate both word discovery and word-meaning association. In light of empirical findings, the main part of this article presents a computational model that can identify the sound patterns of individual words from continuous speech, using nonlinguistic contextual information, and employ body movements as deictic references to discover word-meaning associations. To our knowledge, this work is the first model of word learning that not only learns lexical items from raw multisensory signals to closely resemble infant language development from natural environments, but also explores the computational role of social cognitive skills in lexical acquisition.     

大学生亲社会倾向、亲社会推理以及它们的相关模式

采用《亲社会倾向测量》和《亲社会推理客观测量》研究了17至20岁大学生的六类亲社会倾向和亲社会推理的状况。发现大学生将利他的亲社会倾向列为六类倾向中的首位,接下来依次是紧急的、情绪性的、依从的、匿名的和公开的亲社会倾向;在亲社会推理五种类型中大学生选择比率最高的是内化价值定向的推理,接下来依次是刻板定向、需要定向和享乐主义定向的推理,所占比率最低的是赞扬定向的推理;六类亲社会倾向与亲社会推理之间具有特定的棚关模式．利他的和匿名的亲社会倾向与内化价值定向和刻板定向的推理正相关、与享乐主义定向及赞扬定向的推理负相关,公开的亲社会倾向与赞扬定向的推理正相关、与需要定向的推理负相关。跨文化比较证实,中美大学生的上述三个方面表现出一定的差异。     

From vulnerability to resilience: learning orientations buffer contingent self-esteem from failure

An experiment examined the buffering effects of a learning orientation following failure in a domain of contingent self-worth. Participants' academic contingencies of self-worth (CSW) and priming with theories of intelligence interacted to affect vulnerability of self-esteem to failure. Participants who had high academic CSW and were primed with an entity theory of intelligence experienced lower self-esteem and higher negative affect following failure than following success on an academic test, but these effects were eliminated when participants with high academic CSW were primed with an incremental theory of intelligence. This study shows that endorsing a learning orientation is an effective way to minimize threat to self-esteem among students whose self-worth is highly contingent on academics and may allow them to persist in the face of challenges and to learn from failure.
