Adaptability to changing circumstances is a key feature of living creatures. Understanding such adaptive processes is central to developing successful autonomous artifacts. In this paper two perspectives are brought to bear on the issue of adaptability. The first is a short term perspective which looks at adaptability in terms of the interactions between the agent and the environment. The second perspective involves a hierarchical evolutionary model which seeks to identify higher-order forms of adaptability based on the concept of adaptive meta-constructs.Task orientated and agent-centered models of adaptive processes in artifacts are considered from these two perspectives. The former is represented by the fitness function approach found in evolutionary learning, and the latter in terms of the concepts of empowerment and homeokinesis found in models derived from the self-organizing systems approach. A meta-construct approach to adaptability based on the identification of higher level meta-metrics is also outlined. 相似文献

Interpersonal theories suggest that depressed individuals are sensitive to signs of interpersonal rejection, such as angry facial expressions. The present study examined memory bias for happy, sad, angry, and neutral facial expressions in stably dysphoric and stably nondysphoric young adults. Participants' gaze behavior (i.e., fixation duration, number of fixations, and distance between fixations) while viewing these facial expressions was also assessed. Using signal detection analyses, the dysphoric group had better accuracy on a surprise recognition task for angry faces than the nondysphoric group. Further, mediation analyses indicated that greater breadth of attentional focus (i.e., distance between fixations) accounted for enhanced recall of angry faces among the dysphoric group. There were no differences between dysphoria groups in gaze behavior or memory for sad, happy, or neutral facial expressions. Findings from this study identify a specific cognitive mechanism (i.e., breadth of attentional focus) that accounts for biased recall of angry facial expressions in dysphoria. This work also highlights the potential for integrating cognitive and interpersonal theories of depression. 相似文献

If X loves Y does it follow that X has reasons to love a physiologically exact replacement for Y? Can love's reasons be duplicated? One response to the problem is to suggest that X lacks reasons for loving such a duplicate because the reason-conferring properties of Y cannot be fully duplicated. But a concern, played upon by Derek Parfit, is that this response may result from a failure to take account of the psychological pressures of an actual duplication scenario. In the face of the actual loss of a loved one and the subsequent appearance of a duplicate, how could we resist the inclination to love? Drawing upon duplication scenarios from Parfit and from Stanislaw Lem's Solaris, this paper will argue that there could be reasons for X to come to love a duplicate of Y but that these would not be identical with the reasons that X had (and may still have) to love Y. Nor (in the case of an agent with a normal causal history) could they be reasons for a love that violates the requirement that love is a response to a relationship and therefore takes time to emerge. 相似文献

Flow state in self-paced and externally-paced performance contexts: An examination of the flow model
ObjectivesKimiecik and Stein's (1992) flow model proposed that personal and situational factors affect the experience of flow. Singer, 1988, Singer, 2000 argued that different mental processes underlie self-initiated and reactive performances. The first purpose of this study was to examine main and interaction effects between imagery use and confidence on flow state in different performance contexts. The second purpose was to assess main and interaction effects between flow state, imagery, and confidence on self-paced service and externally-paced groundstroke performance in tennis.DesignThis field study used a repeated-measures design.MethodA pilot study was conducted to inform the set up of the two performance contexts. Flow states were assessed on two separate occasions, (a) for the service performance, and (b) for the groundstroke performance. A total of 60 junior tennis athletes completed imagery and confidence measures before the field test.ResultsA significant interaction between imagery and confidence was found for flow state in the groundstroke but not in the service task. No significant interaction effects were found for performance outcome. Flow state significantly predicted groundstroke performance, and imagery and confidence predicted service performance.ConclusionsThe examination of flow in different performance contexts is challenging. Imagery and confidence are central to the experience of flow. Flow state appeared to be more important for the externally-paced than self-paced task. The relationship between flow and performance is complex, which requires the conceptual expansion of Kimiecik and Stein's (1992) flow model. 相似文献

Biased attention and dysphoria: Manipulating selective attention reduces subsequent depressive symptoms 总被引:1,自引:0,他引:1
Selective attention for dysphoric stimuli has been observed in individuals with depression and those at risk for depression. To date, no studies have investigated the effects of directly manipulating selective attention for dysphoric stimuli on depressive symptoms. Mild to moderately depressed college students (N=34) were randomly assigned to complete 4 sessions of either attention training (AT) or no training (NT) during a two-week period. Participants completed self-reported assessments of depressive symptoms at baseline, post-training, and follow-up. Participants in the AT condition had a significantly greater decrease in depressive symptoms from baseline to follow-up than participants in the NT condition. This group difference was mediated by change in attention bias. Our findings suggest that biased attention may have a causal role in the maintenance of depressive symptoms. 相似文献

Tūsī, a thirteenth century logician writing in Arabic, uses two logical connectives to build up molecular propositions: ‘if-then’, and ‘either-or’. By referring to a dichotomous Tree, Tūsī shows how to choose the proper disjunction relative to the terms in the disjuncts. He also discusses the disjunctive propositions which follow from a conditional proposition 相似文献

Luciano Floridi presents Information Ethics (IE) as an alternative to traditional moral theories. IE consists of two tenets. First, reality can be interpreted at numerous, mutually consistent levels of abstraction, the highest of which is information. This level, unlike the others, applies to all of reality. Second, everything, insofar as it is an information object, has some degree of intrinsic value and hence moral dignity. I criticize IE, arguing that Floridi fails to show that the moral community should be expanded beyond beings capable of suffering or having preferences. Next, I look at Floridi’s extended case against consequentialism generally and utilitarianism in particular. I try to show that his criticisms are flawed. Third, I argue that, for the most part, it is not clear what IE’s practical implications are. I conclude with a critical discussion of the one area of information ethics, traditionally conceived, that Floridi has written about at length, privacy. 相似文献

This study explored the interrelated job search, unemployment, and coping literature (e.g., Leana & Feldman, 1990 ; McKee‐Ryan, Song, Wanberg, & Kinicki, 2005 ), in which the effects of age, length of unemployment, and coping behaviors on reemployment expectations were investigated. The study included unique demographics in which 65% were long‐term unemployed. Length of unemployment, networking comfort, and job search confidence were significant in a regression, and age was not. Regardless of age, reemployment expectations can be higher if the job seeker has higher levels of networking comfort and/or job search confidence or lower if they have been unemployed for a longer duration. 相似文献

Psychologists have increasingly employed dictionary-based text analysis to examine the language of leadership, as leadership is embedded in a web of negotiated meanings and contextual factors. This research seeks to embed leaders’ rhetorical influence in leader–follower relationships and identify contextual factors that explain the different patterns of effective versus ineffective leaders’ and charismatic versus non-charismatic leaders’ uses of action-oriented terms and negation terms in their inaugural speeches. By analyzing data of 30 U.S. presidents’ inaugural addresses, presidential election outcomes, and leadership styles, I found that effective leaders used action-oriented terms more frequently in their inaugural speeches than ineffective leaders only when follower participation was low, whereas charismatic leaders used negation terms more frequently in their inaugural speeches than non-charismatic leaders only when follower endorsement was low. These findings suggest that effective leaders are attuned to action-related situational cues whereas charismatic leaders are attuned to value-related situational cues. 相似文献
