Reaching out for an object has been broadly discussed within psychoanalysis using the term 'object-seeking'. This article develops the idea that it is a fundamental feature of human beings to reach out for objects in order to survive and/or to gain vitality. Self-love, which is a derivative of object love, is not possible to achieve in a developmental manner without a sufficient phase-specific emotional response to the subject’s object seeking. In terms of psychoanalytic methodology, the present article represents a tradition (e.g. Tähkä) of renewal related to the classique approach, which is a more passive psychoanalytic technique (e.g. Freud and Winnicott). This traditional psychoanalytic methodology is complemented with a more active technique in order to be therapeutically efficient – especially in the treatment of individuals who are not primary neurotic. The four psychoanalytic schools (drive, object relations, ego and self-psychology) are integrated in a patient’s authentic attempt to reach out for the developmental object in the process of meeting.  相似文献

Richard F. Thompson's study of the neurobiological substrates of learning and memory has been a career-long endeavor, chosen early and pursued with uncompromising depth and breadth. His systematic mapping of the major brain systems and mechanisms involved in eyeblink classical conditioning (EBCC) established the essential role of the cerebellum. Investigations of the interactions between the hippocampus and cerebellum are critically important to this literature, given the essential involvement of these structures in trace EBCC as well as an important modulatory role of the hippocampus in delay EBCC. Hippocampal theta (3-7Hz) oscillations are known to reflect a functional state that influences both the timing of unit firing and the potential for neural plasticity in the hippocampus and other structures. Herein we present a brief summary of research demonstrating the behavioral enhancement due to theta and the underlying neurobiological correlates in both hippocampus and cerebellum during EBCC. Hippocampal and cerebellar local field potentials (LFPs) show that these distantly interconnected brain structures become precisely synchronized when conditions favor rapid behavioral acquisition. Our results suggest a major role for theta in coordinating the widely distributed memory system for trace EBCC. These and other important findings reflect Thompson's own work and his early-career mentoring of scientists whose contributions to the EBCC literature have ensured his major and lasting impact on the neurobiology of learning and memory.  相似文献

Along with the rapid worldwide advance of nanotechnology, debates on associated ethical issues have spread from local to international levels. However unlike science and engineering issues, international perceptions of ethical issues are very diverse. This paper provides an analysis of how sociocultural factors such as language, cultural heritage, economics and politics can affect how people perceive ethical issues of nanotechnology. By attempting to clarify the significance of sociocultural issues in ethical considerations my aim is to support the ongoing international dialogue on nanotechnology. At the same time I pose the general question of ethical relativism in engineering ethics, that is to say whether or not different ethical views are irreconcilable on a fundamental level.  相似文献

In speeded choice tasks with variable foreperiods (FPs), individuals behaviourally adapt to various frequency manipulations. Adaptations have been shown to frequencies of different stimulus-response events, to frequencies of different foreperiods, and to frequencies of different event-foreperiod combinations. We have investigated how participants adapt to a situation where all three frequency manipulations are done simultaneously. Three variable foreperiod experiments are reported. In Experiment 1, one target (the peak distributed target) appeared particularly frequently after one particular FP (the peak foreperiod), while another target was less frequent and equally distributed over all foreperiods. In Experiment 2, the equally distributed target was overall more frequent than the peak distributed one. In both experiments, performance advantages for the peak distributed target were specific to the peak foreperiod, and performance advantages at the peak foreperiod were specific to the peak distributed targets. A third experiment showed that, when two differently frequent target are both equally distributed over FPs, the performance distribution over FPs is not significantly different between both targets. Together, the results suggest that participants were able to simultaneously and specifically adapt to frequency manipulations in events, foreperiods, and event-foreperiod combinations.  相似文献

A nationwide survey was conducted to investigate the prevalence of video game addiction and problematic video game use and their association with physical and mental health. An initial sample comprising 2,500 individuals was randomly selected from the Norwegian National Registry. A total of 816 (34.0 percent) individuals completed and returned the questionnaire. The majority (56.3 percent) of respondents used video games on a regular basis. The prevalence of video game addiction was estimated to be 0.6 percent, with problematic use of video games reported by 4.1 percent of the sample. Gender (male) and age group (young) were strong predictors for problematic use of video games. A higher proportion of high frequency compared with low frequency players preferred massively multiplayer online role-playing games, although the majority of high frequency players preferred other game types. Problematic use of video games was associated with lower scores on life satisfaction and with elevated levels of anxiety and depression. Video game use was not associated with reported amount of physical exercise.  相似文献

Trust is essential to personal well-being and economic success, but it cannot occur without accepting the possibility of betrayal. In the experimental trust game, game-theoretic rationality prescribes that trust decisions should depend on the potential risk (egocentric costs and benefits) and the probability of reciprocity (derived from the trustee's temptation to defect). The current work tests the relative weights of these elements. Experiment 1 shows that trust increases when costs decrease and benefits increase. The latter finding is critical because increasing the trustor's benefit also means increasing the trustee's temptation to defect. Hence, this finding suggests that egocentrism prevails over perspective-taking. Experiment 2 shows that the trustee's temptation to defect (negatively) affects trust, but only when the trustor's cost and benefit are favorable. Results are interpreted as reflecting a boundedly rational decision process.  相似文献

Three general properties of social stereotypes are the perception of differences between ingroups and outgroups (intergroup differentiation), the perception of ingroups as having more desirable attributes than outgroups (ingroup favoritism), and the greater accuracy of ingroup perceptions (differential accuracy). We present and test an inductive-reasoning model that accounts for all 3 phenomena, and we explicate the relations among them. Based on empirical evidence, the model assumes that most people have a positive self-image, that they project these self-images more strongly to ingroups than to outgroups, and that their self-images are valid cues for judgments about social groups. Two minimal-group experiments using a crossed-categorization paradigm support the model and provide new evidence for underlying psychological processes.  相似文献

Previous negotiation research predominantly focused on psychological factors that lead to suboptimal compromises as opposed to integrative agreements. Few studies systematically analyzed factors that impact the emergence of hurtful partial impasses (i.e., nonagreements on part of the issues). The present research investigates negotiators' egoistic motivation as a determinant for the emergence of partial impasses. In addition, the authors seek to demonstrate that perspective taking serves as a powerful tool to avoid impasses and to overcome egoistic impediments. Specifically, it was predicted that within an integrative context perspective-takers succeed to exchange concessions on low- versus high-preference issues (i.e., logroll), thereby increasing their individual profits without inflicting hurtful losses upon their counterparts. Three studies were conducted to test these predictions. Study 1 reveals that whereas negotiators' egoistic motivation increases the risk of partial impasses, perspective taking alleviates this risk. Study 2 demonstrates that this beneficial effect of a perspective-taking mindset is limited to integrative negotiations and does not emerge in a distributive context, in which negotiators are constrained to achieve selfish goals by inflicting hurtful losses on their counterparts. Study 3 confirms the assumption that in an integrative context egoistic perspective-takers overcome the risk of impasses by means of logrolling. The findings of the present studies are discussed with respect to their contribution to research on negotiations, social motivation, and perspective taking.  相似文献

Malleability of preferences is a central tenet of behavioral decision theory. How malleable preferences really are, however, is a topic of debate. Do preference reversals imply preference construction? We argue that to claim preferences are construed, a demonstration of more extreme preference malleability than simple preference reversals is required: absolute preference sign changes within participants. If respondents value a prospect positively in 1 condition but negatively in a different condition, preferences cannot be considered stable. Such absolute preference sign changes are possible under uncertainty. In 2 incentive‐compatible experiments, we found participants were willing to pay to take part in a gamble and also demanded to be compensated to take part in a subsequent gamble with identical outcomes and probabilities. Such absolute preference sign changes within participants led to simultaneous risk aversion and risk seeking for the same risky prospect, suggesting that, at least in the domain of risky decisions, consumers' preferences are indeed malleable and construed.  相似文献
