针对当前公民责任意识教育存在的困难,文章从心理学角度出发,指出了当前研究所忽略的整体情境的动力和阻力问题,并尝试根据勒温的场论思想,对中国公民责任意识教育进行了整体和动力分析。通过整体结构的分析,提出了构成公民责任意识情境的三个维度:文化特征(差序格局-团体格局)、关系内容(传统社会的"义"、"利"、"情"和现代社会的"公")和现实程度(现实-虚构)维度。据此以拓扑心理学形式,举例说明了情境与人格交互作用中的动力和阻力因素。在上述个体层面分析的基础上,文章还简述了公民责任意识教育实践的团体动力学原理,并以展望未来论坛为例,介绍了正在兴起的公民责任意识教育的行动策略。 相似文献

This paper applies a contemporary, 'two-track'- transformational as well as archaeological - perspective on psychoanalytic process to clinical issues in the creation of analytic patients: case finding, recommending analysis, and recommending and negotiating the intensification of frequency of sessions in analytic psychotherapy. Central importance is assigned to the role of the mind and analytic identity of the analyst, including the analyst's capacity to maintain an internal analytic frame and analyzing attitude from the very first contact with the patient and throughout the treatment, the analyst's confidence in and conviction about the usefulness of analysis for a given analytic dyad and the role of the analyst's theory, which must be broad and consistent enough to allow the analyst to feel that he or she is operating analytically when addressing non-neurotic (unrepresented and weakly represented mental states) as well as neurotic structures. 相似文献

Abstract: The paper aims at highlighting how our primary understanding of others’ actions is rooted in the mirror mechanism. To this end, the anatomical architecture of the mirror neuron system for action will be outlined as well as its role in grasping goals and intentions in others’ motor behaviour. One further step through the looking glass of social cognition will be referring to the ubiquitous emotional colouring of actions and considering its links with the motor domain. This will allow a clearer perspective on the mechanism underlying our abilities for emotional understanding and on cases in which these abilities are amiss, as in autistic spectrum disorders. 相似文献

Locomotion requires both proactive and reactive control strategies to maintain balance. The current study aimed to: (i) ascertain upper body postural responses following first exposure to a forward (slip) support-surface perturbation; (ii) investigate effects of repeated perturbation exposure; (iii) establish relationships between arms and other response components (trunk; center of mass control). Young adults (N = 11) completed 14 walking trials on a robotic platform; six elicited a slip response. Kinematic analyses were focused on extrapolated center of mass position (xCoM), bilateral upper- and forearm elevation velocity, trunk angular velocity, and step parameters. Results demonstrated that postural responses evoked in the first slip exposure were the largest in magnitude (e.g., reduced backward stability, altered reactive stepping, etc.) and preceded by anticipatory anterior adjustments of xCoM. In relation to the perturbed leg, the large contra- and ipsilateral arm responses observed (in first exposure) were characteristically asymmetric and scaled to the degree of peak trunk extension. With repeated exposure, xCoM anticipatory adjustments were altered and in turn, reduced posterior xCoM motion occurred following a slip (changes plateaued at second exposure). The few components of the slip response that persisted across multiple exposures did so at a lesser magnitude (e.g., step length and arms). 相似文献

A review of Jung’s writing on the ‘feeling‐toned complex’ shows that he considered it to comprise independent, split‐off, psychic elements. Modern advances in scientific thinking and technology, namely Dynamic Systems Theory and neuro‐imaging, allow us to better define and explore this psychic phenomenon. Considering the constellation of the complex as a hierarchy of dynamic systems allows for a prediction of the timing of brain activity. This has been confirmed by two independent studies using fMRI and QEEG while administering the Word Association Experiment, the tool Jung used to investigate brain/psychic functioning over a century ago. Using as a framework the stages of the constellation of a complex viewed as a hierarchy of dynamic systems, I review the neuro‐imaging studies reported by Petchkovsky et al. (2013, 2017) and Escamilla et al. (2018), concluding that quantitative theoretical predictions and experimental results are in agreement within an order of magnitude. The change in attention caused by the constellation of the complex can also be conceived as the switching from a default neuro‐network, a startle response activating executive functioning in the frontal cortex of either the ego‐complex or an autonomous complex. 相似文献

Researchers have reported contradictory results on the effect of static and dynamic stretching on subsequent performance. Due to the importance of performance through static and dynamic stretching, the aim of this study is to investigate the acute effects of static and dynamic stretching protocols on local dynamic stability in lower extremity joint kinematics and muscular activities during pedalling using a nonlinear dynamics approach. Using a randomised crossover trial design, fifteen active males participated voluntarily in this research (mass: 69.02 ± 10.52 kg, height: 174.00 ± 6.74 cm, and age: 21.20 ± 1.47 years) and completed a pedalling trial in situations of without stretching (WS), after static (SS), and dynamic stretching (DS) of lower extremity. The lower extremity joint angles in the sagittal plane and the electrical activity of soleus, gastrocnemius medialis, tibialis anterior, vastus medialis, biceps femoris, and rectus femoris muscles were collected during 30 pedalling cycles at 70 rates per minute. The results of the repeated measure ANOVA indicated that the knee and ankle angle largest LyE was significantly lower in DS compared to WS and SS. The largest LyE in muscle activity is also significantly lower for all the muscles after DS compared to WS and SS (P ≤ 0.05). Regarding the positive effects of DS on the joints and the muscle activity local dynamic stability, it is suggested to use DS than SS in the warm-up program before repetitive activities like pedalling. 相似文献

Piccione and Rubinstein (1997) present and analyse the sequential decision problem of an “absentminded driver”. The driver's
absentmindedness (imperfect recall) leads him to time-inconsistent strategy evaluations. His original evaluation gets replaced
by a new one under impact of the information that the circumstances have changed, notwithstanding the fact that this change
in circumstances has been expected by him all along. The time inconsistency in strategy evaluation suggests that such an agent
might have reason to renege on his adopted strategy. As we shall see, however, this danger is only apparent. There is no serious
problem of dynamic inconsistency in this case. My diagnosis of the case under consideration is in many respects similar to
the one provided by Aumann, Hart and Perry (1997), but the analysis leading to this diagnosis is not quite the same.

In the article texts by John Dewey, JürgenHabermas and Richard Rorty are discussed in thelight of different meanings of the Public. Thisis done by discussing foundational andnon-foundational claims on a philosophy ofpragmatism and democracy, and by looking atdifferent meanings of intersubjectivity. Onecrucial difference I am pointing at, is thatwhile Dewey's intersubjectivity is stemmingfrom philosophical arguments as well aspolitical, Habermas's intersubjectivity isrestricted to the level of (an almostscientific) philosophical abstractargumentation without any concrete language ofpolitics. When it comes to Rorty I stress thathe is far closer than Habermas to Dewey'spragmatism, especially his ambition to includethe specific individuals and to stressindividuality in a philosophy of communicationand public conduct. 相似文献

This essay presents a phenomenological analysis of the functioning of symbols as elements of the life-world with the purpose of demonstrating the interrelationship of individual and society. On the basis of Alfred Schutz's theory of the life-world, signs and symbols are viewed as mechanisms by means of which the individual can overcome the transcendences posed by time, space, the world of the Other, and multiple realities which confront him or her. Accordingly, the individual's life-world divides itself into the dimensions of time, space, the social world and various reality spheres which form the boundaries or transcendences that the I has to understand and integrate. Signs and symbols are described as appresentational modes which stand for experiences originating in the different spheres of the life-world within the world of everyday life, within which they can be communicated, thereby establishing intersubjectivity. Schutz's theory of the symbol explains how social entities – such as nations, states or religious groups – are symbolically integrated to become components of the individual's life-world. The following paper reconstructs Schutz's concept of the symbol as a crucial component of his theory of the life-world, which is seen as an outstanding phenomenological contribution to the theory of the sign and the symbol in general. 相似文献
