The increasing discourse of the concept of intersubjectivity in modern psychoanalysis has pushed the interest in the intrapsychic and its emphasis on drive and object into the background. Authors who wish to avoid a one-sided focus on intersubjectivity usually subscribe to a dual dimensional approach, taking both perspectives into account. In this article, the analytic situation is described not in two, but in three dimensions, the analytic function constituting a third dimension necessary for the interplay between the other two dimensions. Focusing on the analyst's position, the author presents a model that consists of (1) the-analyst-as-subject, (2) the-analyst-as-function, and (3) the-analyst-as-object. The analytic function is understood to be invested with a particular form of desire and it is argued that the asymmetry between this desire of the analyst and the desire of the analysand is a central characteristic of the analytic situation.  相似文献

Political scientists are increasingly exploring the psychological underpinnings of voting behavior using field experimental techniques. Research in psychology demonstrates that positive reinforcement—what I describe as positive social pressure—motivates prosocial behavior. A distinctive feature of the current study is the focus on key subgroups of voters, namely unmarried women and minorities. Attention to these voter subgroups allows us to build upon findings reported in previous studies that leave questions about the generalizability of the reported effects of positive social pressure to key demographic subgroups of voters largely unanswered. This article reports the results of a large‐scale randomized field experiment designed to investigate the impact of positive social pressure on voter turnout. The experiment was conducted during the November 2009 gubernatorial election in New Jersey, and the results suggest positive social pressure mobilizes voters. Moreover, the effects appear to be robust across subgroups of voters, including minorities and unmarried women, and both lower‐ and higher‐propensity voters.  相似文献

A phase field model accounting for plasticity has been developed using an homogenization scheme for interpolating the constitutive laws within the diffuse interface. The influence of plasticity on the growth of a misfitting spherical precipitate, controlled by solute diffusion has been investigated: plasticity in the matrix slows down the transformation. Moreover, an excellent agreement with the corresponding analytical sharp interface solutions has been achieved.  相似文献

The effect of a high magnetic field on the morphology of the MnBi primary phase during the directional solidification has been investigated experimentally and the results show that an application of a high magnetic field has enhanced the faceted growth and the coarsening of the MnBi primary phase. This may be attributed to the effect of a high magnetic field on the diffusion of the solute Mn and the growth anisotropy of the MnBi crystal.  相似文献

In order to motivate the thesis that there is no single concept of causation that can do justice to all of our core intuitions concerning that concept, Ned Hall has argued that there is a conflict between a counterfactual criterion of causation and the condition of causal locality. In this paper I critically examine Hall's argument within the context of a more general discussion of the role of locality constraints in a causal conception of the world. I present two strategies that defenders of counterfactual accounts of causation can pursue to respond to Hall's challenge—including the adoption of a counterfactual condition that is sufficient for causal action-at-a-distance in place of Hall's ‘process’ condition—and conclude that Hall's argument against counterfactual accounts of causation is unsuccessful.  相似文献

Group therapy occupies a curious and ambiguous status in the overall mental health field: groups are recognized and marginalized, sought after and avoided, respected and dismissed as second best to individual therapy. Groups are now practised widely in many services, probably because of the pressure of referrals and increased concern about funding, but even then have a secondary status. The under-recognition of both the value and complexity of groups seems to parallel the problems of theory which are part of the group psychotherapeutic culture. Rather than attempt a comprehensive theory of groups in this article, I intend to present some of the problems about theory and its link to practice, focusing particularly on the ambivalence about groups that I see as a continuing concern. I do so from a position which values theory, seeing in theory the container of understanding which guides psychotherapeutic practice. I do not identify with a critical position which rejects theory. This position recognizes fully the risks and dangers of over-theorizing, the potential to distort human contact through a rigid adherence to theory; however, I write in the spirit of appreciating theory thoughtfully applied as without theory, our work might be impoverished and even impeded.  相似文献

This study reports on my fieldwork experiences applying qualitative research strategies to study child sexual abuse in South Africa. It considers the challenges associated with, at three stages of data collection: ethical clearance, recruitment and data collection, followed by possible solutions. The study also considers the challenges from ethical and epistemological perspectives. I used a reflective self-study to analyse my experiences. My experiences revealed the following challenges: ethical process due to reasons not linked to the content of the research process would cause delays to the field-work. In addition, the use of [formal institutions] welfare institutions as sole research sites would result in a homogenous sample that does not permit comparison of experiences among the abuse cases. The costs to the researcher in terms of emotional and physical investment can be significant.  相似文献

Using the paradigm of habituation learning in the open field, we tested the effects of unilateral microinjections of the agonist nicotine (8.0, 40.0, and 80.0 microg) and the nicotine receptor antagonist mecamylamine (0.1, 1.0, 10.0 microg) into the core of the nucleus accumbens. When injected posttrial, that is, immediately after the first exposure to the open field, nicotine dose-dependently enhanced behavioral habituation during the test on the following day, indicating a facilitation of memory, whereas mecamylamine impaired habituation at the highest dose, but not at the two lower doses. When injected 5 h after the learning trial, nicotine (40 microg) and mecamylamine (10 microg) impaired habituation on the subsequent day. A control experiment did not provide evidence for possible proactive effects of mecamylamine. These findings are discussed with respect to the possible behavioral functions of cholinergic, and especially nicotinic, mechanisms in the nucleus accumbens. They may also be relevant for understanding cholinergic-linked psychopathologies such as Alzheimer's disease, since the nucleus accumbens is one of the sites where cholinergic neurons are lost in this neurodegenerative disease.  相似文献
