present research examined the role of hippocampal NMDA-dependent synaptic potentiation on appetitive instrumental conditioning
under a continuous reinforcement schedule. In the first experiment, low (.025 mg.kg) or moderate (.05 mg/kg) dosages of the
NMDA receptor antagonist, MK801, failed to increase the number of training days required to reach acquisition criterion; number
of training days required to reach criterion for extinction were also unaffected. In the second experiment, a higher dosage
(.10 mg/kg) of MK801 or induction of long-term potentiation failed to alter the number of responses occurring during acquisition.
These data suggest that hippocampal synaptic potentiation does not play a prominent role in instrumental learning with simple
contingency conditions. It is suggested that hippocampal LTP reflects a perceptual process that contributes differentially
to spatial cognition, classical and instrumental conditioning. 相似文献

The role of emotion in the construction of career has not always been clear despite its importance in people's lives and in counseling. Recent conceptualizations suggest that emotion is a complex relational process that is socially constructed. This study illustrates the role of emotion in the construction of career from an action theory perspective. Two parent—adolescent conversations about career from a group of 14 conversations are analysed in detail to demonstrate the ways in which emotions serve to energise action and career and lend context and meaning to the process of constructing career in the family setting. 相似文献

The results of a qualitative research study designed to better understand the developmental processes active in beginning therapists during the first three months of clinical contact is reported. Thirteen beginning therapists were asked to complete a monthly log describing experiences impacting their clinical work and themselves as therapists during their first three months of client contact. Data analysis revealed that the primary developmental theme active during this period of time is the development of therapist confidence. Two additional themes, the development of an internal gauge on which to evaluate current experiences and the development of boundaries around the self as a professional, were also found to be active during this time. These additional themes support the development of therapist confidence. Implications for training and research are identified. 相似文献

Abstract— Pennebaker's (this issue) intervention for writing about emotional experiences shows promise as a module for inclusion in therapeutic packages. There are conceptual, methodological ant practical issues to be considered, however. These issues are discussed, and parallels are drawn from the literatures on the moodregulatory function of dreams and on the effects of social support on health. Although there is evidence that anything about emotional experiences has beneficial effects on health, it is premature to recommend writing intervention as a treatment component for specific problems. What is needed at this point is systematic research to evaluate to clinical utility. 相似文献

The classical conception of rhetoric as the method of reasoned political judgment survived into the Renaissance but was reduced to academic critiques of style and "empty" public rhetoric with the rise of modern science and its representationalist theories of language. Recently, however, rhetoric, textuality, and the "linguistic turn" generally, have become central metaphors in the human sciences. This renewed rhetorical perspective not only fosters a critique of positive philosophy and of scientism in public discourse, it also offers affirmative methods by which persons can construct their civic lives. 相似文献

What is the philosophical significance of the “sublime”, and does this concept still have any relevance to contemporary life? In this essay, I argue that the experience of the sublime is exceptionally important, insofar as it presents us with a general model for the experience of otherness, the encounter with transcendence itself, which might reasonably be viewed as impossible. As Rudolf Otto suggested, the experience of the sublime is closely related to the experience of the sacred; and even in Burke and Kant, the sublime is to be grasped as both an aesthetic and a religious experience which finally opens the individual to that which is greater than herself. Thus, the sublime has become a major theme in postmodern theory, precisely because it gives us access to the sacred and that which is wholly “other.” 相似文献

The first part of this paper proposes a continuum of ideological premises that seeks to account for the broad range of immigrant integration policies adopted by Western democratic states. In the second part, a review of Social Psychological models of immigrant acculturation strategies demonstrates the need to explain more clearly the interactive nature of immigrant and host community relations. The Interactive Acculturation Model (IAM) presented next proposes that relational outcomes are the product of the acculturation orientations of both the host majority and immigrant groups as influenced by state integration policies. The model makes predictions regarding the acculturation combinations most likely to produce consensual, problematic, and conflictual relational outcomes between immigrants and members of the host community. Social psychological research is needed to test the validity of the IAM model empirically. 相似文献
