采用经典落球试验研究范式,同步观察视觉预期和注意指向对腰部姿势肌肉和上肢运动肌肉预期和补偿姿势调节的影响,探索视觉预期和注意指向影响姿势控制的早期心理生理机制。24名青年志愿者(10名男性,14名女性)参与完成本实验,分别在有、无视觉预期以及注意指向"托盘稳定"或者"重心稳定"的实验条件下观察外部姿势干扰对腰部姿势肌肉(L5~S1腰部多裂肌)和上肢动作肌肉(肱二头肌)预期姿势调节(anticipatory postural adjustments,APAs)和补偿姿势调节(compensatory postural adjustments,CPAs)相关时间和强度参数的影响。APAs和CPAs的时间和强度参数通过获取被检肌肉s EMG信号并参照相关检测规范进行。结果显示:(1)视觉预期对多裂肌的APAs启动时间,对肱二头肌的APAs启动时间、APAs强度和CPAs强度有显著影响;(2)注意指向对多裂肌的CPAs启动时间和肱二头肌APAs启动时间有显著影响;(3)视觉预期和注意指向对肱二头肌的APAs启动时间和APAs强度有交互作用。研究认为,突发外部姿势干扰条件下姿势肌肉和动作肌肉的姿势调节策略具有一定的差异,视觉预期和注意指向仅对姿势肌肉的时间参数有影响,对动作肌肉APAs和CPAs时间和强度参数都产生调节作用,表明在中枢神经系统的姿势控制中,人体姿势策略的调节是通过对姿势肌肉和动作肌肉的双重控制来完成的,视觉预期效应和心理指向效应反映在对不同功能肌肉前馈控制和反馈控制相应参数的调节。  相似文献

大学生领悟社会支持的影响因素研究   总被引:21,自引:1,他引:21  
叶俊杰 《心理科学》2005,28(6):1468-1471
该研究以371名大学生为被试,考察了个体的幸福感、控制感和压力对领悟社会支持的影响。结构方程模型分析的结果显示:个体属性和情境因素都直接或间接影响着大学生对社会支持的理解和评价;个体属性的影响相对比较重要;在情境因素中,累积压力比当前压力的影响更为重要。本研究结果表明,领悟社会支持是在个人属性的作用下,个体在不断应对日常生活压力的过程中形成和发展的。  相似文献

This is a paper about the difficulties we as analysts get into when we find that a patient has activated something in our unconscious which we cannot resolve in our work with them. Fordham described at the end of his life, in a number of papers, his difficulties and discomfort at not being able to resolve an impasse with one of his patients. From the conversations we had about this situation I knew this caused them both a lot of pain. After Fordham's death his former patient consulted me. Arising from these consultations I describe how I have understood the impasse to have arisen between Fordham and his patient. This paper links character and clinical interests, personality and impasse, developmental failures and defences of the self. It is a personal statement in which I have struggled to represent the meaning in the pain these two men suffered during their analytic engagement, which lasted more than ten years. The theme of fathers and sons was central to the problem.  相似文献

Two studies examined how people deal with conflicts between their self‐interest concerns and their striving for fairness. Specifically, the affective reactions to outcome arrangements in which people receive better outcomes than comparable other persons, were studied. These arrangements of advantageous inequity constitute situations in which fairness and self‐interest concerns are in conflict. Building on the social psychology of the self, it was predicted, and found, in both field and lab experiments that when people experience a self‐threat, they react more positively to arrangements of advantageous inequity than when not experiencing this threat. This supports the view that people's need for positive information about their selves is an important factor in the underlying psychological processes of the way that people deal with conflicts between their fairness and self‐interest concerns.  相似文献

为考察心理理论与回忆过去、想象将来中内容的关系,153名青少年两周内完成了情景记忆和心理理论等任务。控制了智力、言语能力和执行功能后,线性回归分析发现青少年回忆过去和想象将来时“谈及他人”与心理理论有显著关联(Aajusted R^2=51.6%,F(9,143)=19.00,P〈0.001),不同群体间心理理论的差异也可由其谈及他人数量不同来解释。结果提示。与西方谈论心理状态不同,中国文化下回忆过去和想象将来时“谈及他人”可能是促进心理理论发展的机制。  相似文献

Self‐practice and self‐reflection (SP/SR) is a targeted training tool that is intended to increase CBT competency in therapists. The four articles reviewed in this commentary examine the benefits of SP/SR with various types of therapists, and survey the significant obstacles faced in implementing this tool with clinicians. Collectively, these articles conclude that SP/SR is a valuable tool in improving CBT skill acquisition and preventing burnout, particularly with difficult patients, but that most therapists elect not to use it largely because of the time involved in engaging in it. In this commentary, I suggest that empirical studies with larger samples and controlled designs are needed to build on the wealth of qualitative data collected to date in order to assess the value added by SP/SR compared with other training methods, and in order to determine its impact on a range of therapeutic outcomes. I also suggest that future studies should examine the efficacy of required SP/SR engagement, isolate its critical ingredients, and assess if there are clients and therapists for whom SP/SR is comparably more effective.  相似文献

The primary goal of this experiment was to determine whether the addition of an operant requirement for access to a less costly (continuous reinforcement) patch of future food increased the time horizon over which that future patch decreased intake in a currently available depleting (progressive-ratio) patch. Three groups of 4 rats were tested. Each member of the earned-time group was required to cumulate a fixed-time outside the progressive-ratio patch to obtain access to food in the less costly patch; the fixed-time requirement ranged from 2 to 64 min. Rats in the matched-time group received response-independent access to less costly food at the average delay shown by the earned-time group. Rats in the matched-time no-food group were removed from the chamber at the same average delay without receiving access to less costly food. Two of the earned-time rats showed an increased time horizon relative to that shown by the matched-time rats (approaching 40 min for 1 rat). The other 2 earned-time rats markedly increased instrumental responding but showed suppression of intake only when food was less than 20 min away. The matched-time group showed less suppression of intake over a similar range of delay intervals. Surprisingly, the matched-time no-food animals also showed suppression of intake concentrated at the end of the session, possibly reflecting the receipt of their entire daily ration 30 min after the session. The potential importance of time horizons to the foraging process is clear, but experimenters are still working out paradigms for investigation of these horizons.  相似文献

This paper is an exploration of the relationship between nurturing in all its contexts ‐ among them, the nursing couple and the therapeutic relationship ‐ and the evolution of an individual self. The ideas are illustrated by a case vignette of a Russian patient. An attempt is made to show that when the self as an integral unity of body and soul is addressed in the analytic setting, ‘nutritional dreams’ emerge as expressions of the self‐in‐action. Certain psycholinguistic features of the Russian cultural context are described which suggest a link of meaning between development of the self and secure parenting. This linguistic association may facilitate the process of self‐centering.  相似文献

Starting from our collective initiative to work on the theme of ‘The strength of the name’, which has given rise both to a conference as well as a documentary called: And their name, they have changed it, I have sought to draw attention in this article to the difference between proper names, patronymic names, and the so‐called Name‐of‐the‐father. Pronouncing names involves designating the languages of names, which also refer to the accents of names, since I have proposed the idea that each name is evocative of a language, and that changing it also modifies the language of the name. I have approached the question of the name by considering cases of name‐changes, essential with regard to Ashkenazi Jewish families who changed their name after the Shoah, along with the trauma that numerous Jewish families suffered after the war. French jurisprudence does not permit reversion to the original name, once it has been changed to a more French‐sounding name, owing to the immutability of the name and the foreign sound of the names of origin.  相似文献

This paper explores the evolution of Michael Fordham's ideas concerning ‘defences of the self’, including his application of this concept to a group of ‘difficult’ adult patients in his famous 1974 paper by the same name. After tracing the relevance of Fordham's ideas to my own discovery of a ‘self‐care system’ in the psychological material of early trauma patients (Kalsched 1996 ), I describe how Fordham's seminal notions might be revisioned in light of contemporary relational theory as well as early attachment theory and affective neuroscience. These revisionings involve an awareness that the severe woundings of early unremembered trauma are not transformable through interpretation but will inevitably be repeated in the transference, leading to mutual ‘enactments’ between the analytic partners and, hopefully, to a new outcome. A clinical example of one such mutual enactment between the author and his patient is provided. The paper concludes with reflections on the clinical implications of this difficult case and what it means to become a ‘real person’ to our patients. Finally, Jung's alchemical views on transference are shown to be useful analogies in our understanding of the necessary mutuality in the healing process with these patients.  相似文献
