Both science and theology have lately faced a crisis of authority. Their shared realization of the extent to which knowledge is underdetermined by the data and socially constructed provides a kind of common ground for reconsideration of their respective methods of inquiry as well as of the status of the claims they have warrant to make. Both fields are now consciously and critically employing a models approach. This article proposes criteria for assessing models and applies the criteria to one model from each field. The model of understanding evolution as a struggle for existence is considered from the field of science, and the traditional model for understanding the God-world relation as that of a king's relation to his kingdom is considered from the field of theology. Each of these models is evaluated with respect to its credibility, religious viability, and moral adequacy. In each case an alternative analogy is proposed and argued for. 相似文献

Abstract— We investigated how varying the number of unique pans within an object influences recognition across changes in viewpoint The stimuli were shaded objects composed of five three-dimensional volumes tinted end to end with varying connection angles Of the five volumes, zero, one, three, or jive were qualitatively distinct (e g, brick vs cone), the rest being tubes Sequential-matching and naming tasks depth Three major results stand out First, regardless of the number of distinct parts, there was increasingly poorer recognition performance viewpoint change for objects with one unique part was less than that for the other objects Third, additional pans beyond a single unique part produced strong viewpoint dependency comparable to that ob representations encode both quantitative and qualitative features 相似文献

How can we explain that an assertion on something perceived can be understood in the same manner by somebody who cannot perceive that scene? This problem bases the interest in computational linguistics in how listener modeling could possibly be harmonized with reference semantics. Mental images substituting real perception appear as a way out. The architecture of the listener model has to be adapted to the creation and use of such pictorial data structures. Furthermore, the relation between the latter and a verbal (i. e., propositional) representation must be understood. The resulting architecture of a listener model with reference semantics can be employed to solve communicational problems from three general classes in a better way, as is demonstrated by an example implementation. 相似文献

Two experiments investigated the influence of situational pragmatics on the selective use of specific instances and generalized knowledge structures to make social inferences. In Experiment 1, social inferences were made in an unfamiliar domain similar in structure to a typical situation of social greetings and address, but devoid of useful cues to social schemas. Participants were told that either one or another of the features of the situation was more pragmatically important for deriving inferences about appropriate social behaviour; consistent with predictions from a computational model of analogical mapping (ACME), they made reliable inferences based on analogies to specific instances, with the situational importance of relations guiding the selection of the optimal analogue. In Experiment 2, social inferences were examined in the more familiar domain of predicting social behavior between low and high status persons and between members of an ingroup and an outgroup in Japan. The availability of specific examples was varied, as was the perceived importance of status and group membership. The situation was isomorphic to that in the first experiment, except for the availability of generalized knowledge structures to guide inferences. Participants made relatively veridical inferences that were sensitive to variations in the pragmatic importance of dimensions. Provision of specific analogues had little impact on inferences, suggesting that participants were relying instead on more general and cross-culturally applicable knowledge about adjusting social relations according to situational pragmatics. 相似文献

The primary objective of the present investigation was to examine adaptive functioning in the families of patients with a wide range of psychiatric disorders. Seven dimensions of family functioning, as measured by the Family Assessment Device (FAD), were compared across families of patients with a schizophrenia spectrum disorder (n = 61 ), bipolar disorder (n = 60 ), major depression (n = 111 ), anxiety disorder (n = 15 ), eating disorder (n = 26 ), substance abuse disorder (n = 48 ), and adjustment disorder (n = 46 ). Families in each psychiatric group were also compared to a control group of nonclinical families (N = 353 ). Results indicated that regardless of specific diagnosis, having a family member in an acute phase of a psychiatric illness was a risk factor for poor family functioning compared to the functioning of control families. However, with few exceptions, the type of the patient's psychiatric illness did not predict significant differences in family functioning. Thus, having a family member with a psychiatric illness is a general stressor for families, and family interventions should be considered for most patients who require a psychiatric hospitalization for either the onset of, or an acute exacerbation of, any psychiatric disorder. 相似文献

We studied the academic effects on peers without disabilities of serving as peer supports for students with disabilities in general education classrooms. Three peers were studied using a range of indicators, including academic engagement, coursework performance, and social validity assessments. Peers assisting a student with disabilities via curricular adaptation, assignment completion, and social facilitation constituted the multicomponent independent variable. We used withdrawal or multiple baseline designs to demonstrate positive benefits for peers for all measures used. In addition, follow-up data for 2 peers indicated that the positive changes associated with serving as a peer support were maintained for up to 2 months. Our results are discussed in relation to the possible academic and social effects of providing peer supports in general education classrooms for students with and without disabilities. 相似文献
