A conceptual integration and review are presented of three separate research programmes informed by the theory of lay epistemics (Kruglanski, 1989 Kruglanski, A. W. 1989. Lay epistemics and human knowledge: Cognitive and motivational bases, New York: Plenum. [Crossref] [Google Scholar]). They respectively address the “why”, “how”, and “who” questions about human knowledge formation. The “why” question is treated in work on the need for cognitive closure that propels epistemic behaviour and affects individual, interpersonal, and group phenomena. The “how” question is addressed in work on the unimodel (Kruglanski, Pierro, Mannetti, Erb, & Chun, 2007 Kruglanski, A. W., Pierro, A., Mannetti, L., Erb, H. P. and Chun, W. Y. 2007. “On the parameters of social judgement”. In Advances in experimental social psychology, Edited by: Zanna, M. P. Vol. 39, 255296. New York: Academic Press.  [Google Scholar]) depicting the process of drawing conclusions from the “information given”. The “who” question is addressed in work on “epistemic authority” highlighting the centrality of source effects (including oneself as a source) in human epistemic behaviour. These separate research paradigms explore facets of epistemic behaviour that jointly produce human knowledge, of essential significance to people's’ individual and social functioning.  相似文献

According to a common thesis about normative reasons for action, you have a reason to perform a given action only if you can act for that reason. This thesis has long had broad appeal and is intended to capture the practical character of practical reasons. I’ll call it the ‘Practicality Thesis’. Recently, however, various writers have developed subtly different objections to it, each designed to show that there can be actions you have a reason to perform even though you could not act for that reason – because, were you aware of the reason-giving facts in the ways needed to act for the reason, it would no longer be a reason for you to so act. This article defends the Practicality Thesis against such objections. It considers some extant defences but shows that these are inadequate. It then advances an alternative approach intended to counter any structurally similar objection.  相似文献

Previous accounts of cognitive skill acquisition have demonstrated how procedural knowledge can be obtained and transformed over time into skilled task performance. This article focuses on a complementary aspect of skill acquisition, namely the integration and reuse of previously known component skills. The article posits that, in addition to mechanisms that proceduralize knowledge into more efficient forms, skill acquisition requires tight integration of newly acquired knowledge and previously learned knowledge. Skill acquisition also benefits from reuse of existing knowledge across disparate task domains, relying on indexicals to reference and share necessary information across knowledge components. To demonstrate these ideas, the article proposes a computational model of skill acquisition from instructions focused on integration and reuse, and applies this model to account for behavior across seven task domains.  相似文献

This article traces the development of the World Health Organization's emphasis on psychological and behavioural factors in health and notes its encouragement of recognition of these factors by member states. The article further outlines the reasons for this increasing recognition and stresses the important role of psychological and behavioural factors in the maintenance of health and prevention of illness.  相似文献

The primary aim of this equivalence study was to compare the outcome of a brief group therapeutic intervention, based on the principles of dynamic interpersonal therapy (DIT) with an intervention based on cognitive behavioural therapy (CBT) in patients suffering from medically unexplained somatic symptoms (MUSS). Participants were 89 patients (aged 18 to 62) who were offered 20 sessions of either DIT or CBT, as central part of a treatment package, consisting of art therapy, psychomotor therapy, social therapy and physical therapy. Measurements were conducted at baseline, 10 weeks and 20 weeks, using self-rating scales measuring the level of anxiety and depression, the severity of medically unexplained symptoms and quality of life. Results showed that CBT and DIT were comparable. The conclusion was that it is recommended to design a larger scale randomised controlled trial to further elaborate the short-term and long-term effects of this novel psychodynamic group therapy for MUSS patients.  相似文献

Diagnosis of Alzheimer's disease (AD) requires evidence of progressive decline in cognitive function. However, many tests used to assess cognitive function suffer from considerable practice effects, reducing their reliability. Several studies have reported that the ability to do two things at once, or dual tasking, is impaired in AD, but unaffected by healthy ageing. The apparent specificity of this impairment suggests that this assessment may be particularly useful in the early diagnosis of AD, but the reliability of this assessment remains unknown. Therefore, this study investigated simultaneous performance of digit recall and tracking tasks across six testing sessions in eight people with AD, eight healthy older adults and eight healthy younger adults. The results found that dual-task performance was unaffected by healthy ageing, but significantly impaired in AD, with no effect of repeated exposure. The absence of any improvements in performance despite increased familiarity with the task's demands suggests that not only is the dual-task assessment well suited for monitoring progression over time, but also that dual tasking involves a specific cognitive function which is impaired in the AD brain.  相似文献

Successfully explaining and replicating the complexity and generality of human and animal learning will require the integration of a variety of learning mechanisms. Here, we introduce a computational model which integrates associative learning (AL) and reinforcement learning (RL). We contrast the integrated model with standalone AL and RL models in three simulation studies. First, a synthetic grid‐navigation task is employed to highlight performance advantages for the integrated model in an environment where the reward structure is both diverse and dynamic. The second and third simulations contrast the performances of the three models in behavioral experiments, demonstrating advantages for the integrated model in accounting for behavioral data.  相似文献

Individual differences in uncertainty have been associated with heightened anxiety, stress and approach-oriented coping. Intolerance of uncertainty (IU) is a trait characteristic that arises from negative beliefs about uncertainty and its consequences. Researchers have established the central role of IU in the development of problematic worry and maladaptive coping, highlighting the importance of this construct to anxiety disorders. However, there is a need to improve our understanding of the phenomenology of IU. The goal of this paper was to present hypotheses regarding the similarities and differences between IU and three related constructs – intolerance of ambiguity, uncertainty orientation, and need for cognitive closure – and to call for future empirical studies to substantiate these hypotheses. To assist with achieving this goal, we conducted a systematic review of the literature, which also served to identify current gaps in knowledge. This paper differentiates these constructs by outlining each definition and general approaches to assessment, reviewing the existing empirical relations, and proposing theoretical similarities and distinctions. Findings may assist researchers in selecting the appropriate construct to address their research questions. Future research directions for the application of these constructs, particularly within the field of clinical and health psychology, are discussed.  相似文献

Introduction and objectivesAfter leading a validation of questionnaires about three fundamental needs in French language (need for cognition, closing and evaluation), we tested in two studies that fundamental needs could be subjected to social constraints and could be considered differently than exclusively like stable personality characteristics and motivational drivers of action.MethodUsing the paradigm of judges (study 1) and the paradigm of identification (study 2), the results argue for a normative approach, at least as regards the need for cognition and assess.ResultsThe results of the first study show that individuals consider more favorably targets with strong need rather than low need and especially in social contexts with high social utility (that is to say, the professional context in comparison with the friendly context). The results of the second study show that when the questionnaires about needs “as would a person having been previously well or poorly assessed” participants get higher scores high on the need for cognition questionnaire in the first case than in the second. The results regarding the need for closure are more mixed.ConclusionThe results are discussed in a socio-normative perspective.  相似文献
