Abstract. What is the relationship between natural science, social science, and religion? The dominant paradigm in contemporary social science is scientism, the attempt to apply the methods of natural science to the study of society. However, scientism is problematic: it rests on a conception of natural science that cannot be sustained. Natural scientific understanding emerges from an instrumental and objectifying relation to the world; it is oriented toward control and manipulation of the physical world. Social-scientific understanding, by contrast, must begin with a practical and meaningful relation to the world: it is oriented toward the mediation of values and objective possibilities in the social world. Social science is therefore a form of practical reason based on objective claims. But while social-scientific understanding starts with interpretation, its possibilities by no means end there. In particular, by developing abstract and objectified models of society as a system, social science opens existing social organization to critical reflection. Religion, by contrast, is a form of speculative reason about ultimate values, based on subjective claims of religious experience. Social science nevertheless shares with religion an orientation toward values and concern with the “good life.”  相似文献

This article discusses the essence and form of various types of metatheory, paying special attention to metaphilosophy. It suggests the idea of the metatheoretical model—a completely new approach in philosophical discussion—and considers this concept with regard to the Platonic model and the Rhodian model. These models permit two different systems of metatheoretical construction. The paradigms of modern science allow the formation of metatheories that help further the development of logical, mathematical, and similar sciences. The Rhodian model allows the discovery of methods that are helpful in building certain types of theory, as well as suggesting and examining theories that have special metatheoretical features and revealing their common features and differences with regard to other theories. The article discusses the complicated problem of the interrelation between philosophy and metaphilosophy and shows that metaphilosophy is also philosophy, not in the sense that metaphilosophy is a special part of philosophy but rather in the sense that metaphilosophy is a special kind of functioning of philosophy itself.  相似文献

Ten individuals with dizziness participated in a longitudinal study on the relationship between stress and dizziness. The participants rated dizziness and stress on visual analogue scales twice daily for a period of 28 days (in all 56 data points). The ratings of stress included physical stress, mental stress, emotional stress, and the presence of stressful events. The data was analysed by means of time-series analysis (ARIMA), and the temporal associations investigated by lagged correlations. Results showed concurrent associations between dizziness and mental and emotional stress. However, individual differences were observed indicating complex and diverse patterns of association between different forms of stress and dizziness.  相似文献

Two studies were conducted to test a two-stage model of the psychological mechanisms underlying the overconsumption of scarce resources in small groups. The model proposes that members of groups sharing resources first anchor their consumption choices on an “equal-division” heuristic and then, given sufficient cognitive capacity, adjust their choices in a self-serving direction. The results from both studies support the model. The first study found that when faced with a common resource pool almost all group members expressed thoughts regarding equality; however, individuals with sufficient cognitive capacity requested more from the pool and expressed more task-relevant thoughts than individuals lacking the necessary cognitive resources. The second study provided additional support for the two-stage model by demonstrating that group members' cognitions occur in the order predicted by the model and by demonstrating that an individual difference, social value orientation, affects thought processes only when individuals are not experiencing high cognitive loads. Implications are discussed.  相似文献

The tripartite influence model of body image and eating disturbance is a recent theoretical approach that includes a test of direct (peer, parental, and media factors) and mediational links (internalization of societal appearance standards, appearance comparison processes) as factors potentially leading to body dissatisfaction and eating disturbance. The theory was evaluated in the current study in a sample of 391 adolescent females. A structural equation model that evaluated the tripartite model replicated previous findings reported by Keery, van den Berg and Thompson (2004) [Keery, H., van den Berg, & Thompson, J. K. (2004). A test of the tripartite influence model of body image and eating disturbance in adolescent girls. Body Image: An International Journal of Research, 1, 237–251.]. Additionally, a second model extended these findings, suggesting that peer and media influences are more important than parental influences. The results are discussed in light of the need for prevention programs to incorporate formative influences and mediational processes in the construction of intervention strategies.  相似文献

Geometric alterations to the boundaries of a virtual environment were used to investigate the representations underlying human spatial memory. Subjects encountered a cue object in a simple rectangular enclosure, with distant landmarks for orientation. After a brief delay, during which they were removed from the arena, subjects were returned to it at a new location and orientation and asked to mark the place where the cue had been. On some trials the geometry (size, aspect ratio) of the arena was varied between presentation and testing. Responses tended to lie somewhere between a location that maintained fixed distances from nearby walls and a location that maintained fixed ratios of the distances between opposing walls. The former were more common after expansions and for cued locations nearer to the edge while the latter were more common after contractions and for locations nearer to the center. The spatial distributions of responses predicted by various simple geometric models were compared to the data. The best fitting model was one derived from the response properties of 'place cells' in the rat hippocampus, which matches the 'proximities' 1/(d+c) of the cue to the four walls of the arena, where d is the distance to a wall and c is a global constant. Subjects also tended to adopt the same orientation at presentation and testing, although this was not due to using a view matching strategy, which could be ruled out in 50% of responses. Disoriented responses were most often seen where the cued location was near the center of the arena or where the long axis of a rectangular arena was changed between presentation and testing, suggesting that the geometry of the arena acts as a weak cue to orientation. Overall, the results suggest a process of visual landmark matching to determine orientation, combined with an abstract representation of the proximity of the cued location to the walls of the arena consistent with the neural representation of location in the hippocampus.  相似文献

Two experiments are reported in which the ratio of the average times spent in the terminal and initial links (Tt/Ti) in concurrent chains was varied. In Experiment 1, pigeons responded in a three-component procedure in which terminal-link variable-interval schedules were in constant ratio, but their average duration increased across components by a factor of two. The log initial-link response ratio was a negatively accelerated function of Tt/Ti. Overall, the data were well described by Grace's (1994) contextual choice model (CCM) with temporal context represented as (Tt/Ti)k or 2Tt/(Tt + Ti), and by Mazur's (2001) hyperbolic value-added model (HVA), with each model accounting for approximately 93% of the variance. In Experiment 2, fixed-parameter predictions for each model were generated, based on the data from Experiment 1, for conditions in which Tt/Ti was varied over a more extreme range. Data were consistent with the predictions of CCM with temporal context represented as 2Tt/(Tt + Ti) and to a lesser extent as (Tt/Ti)k, but not with HVA. Overall, these results suggest that preference increases as a hyperbolic function of Tt/Ti when terminal-link duration is increased relative to initial-link duration, with the terminal-link schedule ratio held constant.  相似文献
