Over the past 10 years, theorists have suggested that bipolar disorder symptoms result from increases and decreases in the activity of the Behavioral Activation or Facilitation System (BAS or BFS) and the Behavioral Inhibition System (BIS). These neurobehavioral systems are thought to determine the intensity of affective and behavioral responses to incentives and threats. This study examined cross-sectional and prospective associations of self-reported BIS and BAS with mania and depression in a sample of 59 individuals diagnosed with Bipolar I disorder. Depression was tied to BIS, pointing to the importance of sensitivity to threats in depression. However, links between BIS and depression appeared state-dependent. BAS subscales did not correlate with manic symptoms in a state-dependent manner; however, BAS (total scale and reward responsiveness subscale) predicted relative intensification of manic symptoms over time. Thus, evidence suggests that BAS sensitivity may constitute a vulnerability to mania among persons diagnosed with bipolar disorder. Discussion focuses on the integrative potential of the BIS/BAS constructs for linking psychosocial and biological research on bipolar disorder. 相似文献

Why older adults make more immediate treatment decisions about cancer than younger adults 总被引:2,自引:0,他引:2
Literature relevant to medical decision making was reviewed, and a model was outlined for testing. Two studies examined whether older adults make more immediate decisions than younger adults about treatments for prostate or breast cancer in authentic scenarios. Findings clearly showed that older adults were more likely to make immediate decisions than younger adults. The research is important because it not only demonstrates the consistency of this age-related effect across disease domains, gender, ethnic groups, and prevalent education levels but begins to investigate a model to explain the effect. Major reasons for the effect focus on treatment knowledge, interest and engagement, and cognitive resources. Treatment knowledge, general cancer knowledge, interest, and cognitive resources relate to different ways of processing treatment information and preferences for immediate versus delayed decision making. Adults with high knowledge of treatments on a reliable test tended to make immediate treatment decisions, which supports the knowledge explanation. Adults with more cognitive resources and more interest tended to delay their treatment decisions. Little support was found for a cohort explanation for the relationship between age and preference for immediate medical decision making. 相似文献

This review provides a critical analysis of the central nervous system effects of acute and chronic methamphetamine (MA) use,
which is linked to numerous adverse psychosocial, neuropsychiatric, and medical problems. A meta-analysis of the neuropsychological
effects of MA abuse/dependence revealed broadly medium effect sizes, showing deficits in episodic memory, executive functions,
information processing speed, motor skills, language, and visuoconstructional abilities. The neuropsychological deficits associated
with MA abuse/dependence are interpreted with regard to their possible neural mechanisms, most notably MA-associated frontostriatal
neurotoxicity. In addition, potential explanatory factors are considered, including demographics (e.g., gender), MA use characteristics
(e.g., duration of abstinence), and the influence of common psychiatric (e.g., other substance-related disorders) and neuromedical
(e.g., HIV infection) comorbidities. Finally, these findings are discussed with respect to their potential contribution to
the clinical management of persons with MA abuse/dependence. 相似文献

A long and lasting problem in agent research has been to close the gap between agent logics and agent programming frameworks. The main reason for this problem of establishing a link between agent logics and agent programming frameworks is identified and explained by the fact that agent programming frameworks have hardly incorporated the concept of a declarative goal. Instead, such frameworks have focused mainly on plans or goals-to-do instead of the end goals to be realised which are also called goals-to-be. In this paper, the programming language GOAL is introduced which incorporates such declarative goals. The notion of a commitment strategy—one of the main theoretical insights due to agent logics, which explains the relation between beliefs and goals—is used to construct a computational semantics for GOAL. Finally, a proof theory for proving properties of GOAL agents is introduced. Thus, the main contribution of this paper, rather than the language GOAL itself, is that we offer a complete theory of agent programming in the sense that our theory provides both for a programming framework and a programming logic for such agents. An example program is proven correct by using this programming logic. 相似文献

From a developmental perspective, it has been reasoned that over the course of development children make differential use of available landmarks in the surroundings to orient in space. The present study examined whether children can learn to apply different spatial strategies, focusing on different landmark cues. Children aged 7 and 10 years were tested on an object‐location memory task in which they learned a location relative to a direct cue or to indirect cues. Both age groups performed equally well on the direct test condition. However, children 7 years of age had difficulties with orienting relative to the indirect landmarks. Interestingly, their performance increased significantly with more relevant experience. Different explanations for these findings are discussed. 相似文献

In this article, we develop a theoretically substantiated narrative framework for assessing psychotherapy practices, based on a big and small story approach. This approach stretches the narrative scope of these practices by making explicit and advancing small story counseling. We demonstrate how this framework can be a reflection tool by systematically applying six story dimensions to an example from army counseling. Small story dimensions one (multiple storytellers) and three (ways of ordering experience) draw attention to which persons and stories we do not engage with in counseling practices. Small story dimension two (future and on-going temporal orientation) marks a shift towards language of (future) potential, rather than a language of deficit. Small story dimensions four (low tellability) and five (fluent moral stance), reinstate the art of listening to client words, and remind us to resist the inclination to interpret these too easily in terms of a specific counseling theory or moral framework. Finally, small story dimension six (embeddedness) encourages counseling-on-the-move. Finally, we discuss the implications of widening the narrative scope of psychotherapy and counseling, such as the need to develop small story competence and to assess the therapeutic quality of everyday talk. 相似文献
