Recent years have seen considerable interest in procedures for computing finite models of first-order logic specifications. One of the major paradigms, MACE-style model building, is based on reducing model search to a sequence of propositional satisfiability problems and applying (efficient) SAT solvers to them. A problem with this method is that it does not scale well because the propositional formulas to be considered may become very large.We propose instead to reduce model search to a sequence of satisfiability problems consisting of function-free first-order clause sets, and to apply (efficient) theorem provers capable of deciding such problems. The main appeal of this method is that first-order clause sets grow more slowly than their propositional counterparts, thus allowing for more space efficient reasoning.In this paper we describe our proposed reduction in detail and discuss how it is integrated into the Darwin prover, our implementation of the Model Evolution calculus. The results are general, however, as our approach can be used in principle with any system that decides the satisfiability of function-free first-order clause sets.To demonstrate its practical feasibility, we tested our approach on all satisfiable problems from the TPTP library. Our methods can solve a significant subset of these problems, which overlaps but is not included in the subset of problems solvable by state-of-the-art finite model builders such as Paradox and Mace4. 相似文献

Historians of psychology, notably Boring, fostered Fechner's idea that Weber's law is the indispensable basis for the derivation of the logarithmic psychophysical law. However, it is shown here that Bernoulli in 1738 and Thurstone in 1931 derived the logarithmic law using principles other than Weber's law and that Fechner and Thurstone based their derivations on the principles originally employed by Bernoulli. It is concluded that awareness of researchers about Bernoulli's and Thurstone's derivations could expand the directions of research on the form of the psychophysical law. © 2009 Wiley Periodicals, Inc. 相似文献

The involvement of working memory (WM) was examined in two types of mental calculation tasks: exact and approximate. Specifically, children attending Grades 3 and 4 of primary school were involved in three experiments that examined the role of verbal and visuospatial WM in solving addition problems presented in vertical or horizontal format. For Experiment 1, the children were required to solve addition problems with carrying. For Experiment 2, they were required to solve addition problems without carrying. Then, for Experiment 3, the children needed to solve approximate problems with and without carrying. Results confirmed that different WM components are involved in solving mental addition problems. In Experiment 1, horizontally presented addition problems were more impaired than vertically presented ones, according to a verbal WM load; conversely, vertically presented addition problems were more affected by a visuospatial WM load, especially when the children were required to perform approximate calculations. In Experiment 2, this pattern emerged in neither exact nor approximate calculations. Finally, in Experiment 3, the specific involvement of WM components was observed only in problems with carrying. Overall, these results reveal that both approximate calculation and carrying procedures demand particularly high WM resources that vary according to the task's constraints. 相似文献

This paper examines the results of a systematic analysis, organised by the Italian Ministry of Education, University and Research, of private psychotherapy training in Italy. Since 1989, training in psychotherapy in Italy has been governed by a national law which recognises both public and private institutions. While the public system usually comprises approximately 150 students, the private system has grown significantly over time, registering thousands of students in hundreds of schools (for example, 19,123 students in 212 schools in 2011). Systematic analysis variables included geographical distribution, theoretical approaches, training methods, student and teacher characteristics, student’s personal psychotherapy, supervision and apprenticeships. Data were obtained from 92% of the schools. The primary issues discussed in this paper are as follows: the uneven geographical distribution of the schools; the disorderly amalgamation of traditional scientific paradigms; programmes which concentrate on theory and fail to meet international guidelines. One key issue is the excess supply with regard to demand, meaning that recently graduated psychotherapists (especially women) risk underemployment and financial hardship. Student enrolment is also increasingly problematic. This is the first paper to present an in-depth analysis of one European country’s situation in this field. The authors believe it will foster comparison and discussion internationally. 相似文献

The study explored whether participants could directly evaluate sensory ratios. The results indicate that they did not exhibit this ability for the extensive continuum of length and the intensive continua of brightness and brightness difference. Functional measurement analysis, combined with a chronometric analysis of responses, indicated that participants used mental counting for length and used difference evaluation for brightness and brightness difference. The finding that participants evaluated brightness differences under instructions to evaluate brightness ratios suggests that difference judgments may be a general human capability. It resolves questions raised by prior tests of Torgerson’s conjecture and by prior consistency tests of ratio evaluation. 相似文献

Given the prominence of Muslim veils—in particular the hijab and full‐face veil—in public discourse concerning the place of Muslims in Western society, we examined their impact on non‐Muslims’ responses at both explicit and implicit levels. Results revealed that responses were more negative toward any veil compared with no veil, and more negative toward the full‐face veil relative to the hijab: for emotions felt toward veiled women (Study 1), for non‐affective attitudinal responses (Study 2), and for implicit negative attitudes revealed through response latency measures (Studies 3a and 3b). Finally, we manipulated the perceived reasons for wearing a veil, finding that exposure to positive reasons for wearing a veil led to better predicted and imagined contact (Study 4). Practical and theoretical implications are discussed. 相似文献

This study tests the hypothesis that the ability to inhibit already processed and actually irrelevant information could influence performance in the listening span test (Daneman & Carpenter, 1980) and have a crucial role in reading comprehension. In two experiments, the listening span test and a new working memory test were given to two groups of young adults, poor and good comprehenders, matched for logical reasoning ability. In Experiment 1, the poor comprehenders had a significantly lower performance in the listening span test associated to a higher number of intrusions-that is, recalled words that, in spite of being in sentence form, were not placed in the last position. In Experiment 2, a new working memory test was devised in order to analyse more effectively the occurrence of intrusions. Subjects were required to listen to a growing series of strings of animal and non-animal words. Whilst listening, they had to detect when an animal word occurred, and at the end of each series they had to recall the last word of each string. The poor comprehenders obtained a significantly lower performance in the memory task and made a higher number of intrusions, particularly of animal words. 相似文献

In this contribution, which takes account of important findings in neuroscientific as well as psychoanalytic research, the authors explore the meaning of the deep‐going distortions of psychic functioning occurring in hallucinatory phenomena. Neuroscientific studies have established that hallucinations distort the sense of reality owing to a complex alteration in the balance between top‐down and bottom‐up brain circuits. The present authors postulate that hallucinatory phenomena represent the outcome of a psychotic's distorted use of the mind over an extended period of time. In the hallucinatory state the psychotic part of the personality uses the mind to generate auto‐induced sensations and to achieve a particular sort of regressive pleasure. In these cases, therefore, the mind is not used as an organ of knowledge or as an instrument for fostering relationships with others. The hallucinating psychotic decathects psychic (relational) reality and withdraws into a personal, bodily, and sensory space of his own. The opposing realities are not only external and internal but also psychic and sensory. Visual hallucinations could thus be said to originate from seeing with the ‘eyes’ of the mind, and auditory hallucinations from hearing with the mind's ‘ears’. In these conditions, mental functioning is restricted, cutting out the more mature functions, which are thus no longer able to assign real meaning to the surrounding world and to the subject's psychic experience. The findings of the neurosciences facilitate understanding of how, in the psychotic hallucinatory process, the mind can modify the working of a somatic organ such as the brain. 相似文献
