Summary The theory of the square of opposition has been worked out many centuries ago as a part of Aristotelian logic of terms.In spite of its inexactness (for instance it is not possible to decide whether the termsquare of opposition is a logical or a metalogical term) this theory is included without any changes in the usual elementary course of logic.The author defines the square of opposition in the language of the logic of propositions (see Def. 1.000) and derives from this definition the usual laws of the square of opposition and several new theorems.  相似文献

This document, widely circulated in India, argues that the Hindu‐Muslim problem has political, socio‐economic and religious aspects. Here the emphasis is on the Muslim component. It was political hostility which assumed the form of religious hostility. The rise of religio‐cultural separatism and Islamization must be viewed not simply as a facet of ‘Muslim fanaticism’ but rather as a sociological process which resulted from the political struggles between the élites of the two communities and of a heightened political consciousness. But the identity of the Muslims of India remains. Their ‘Muslimness’ cannot completely submerge their ‘Indianness’. Whereas Hindus are asked to show respect for the Muslim minority's cultural‐religious sensibilities, Muslims should opt for a progressive and not a regressive indentity.  相似文献

This paper is concerned with the development of a learning theory model of neurosis which would not be susceptible to the many criticisms which can be made of former models. Two widely favoured models—those of Freud and Skinner—are rejected because they are either non-falsifiable or tautological. The Watson and Mowrer models are rejected because they have been experimentally invalidated. The model here suggested differs from previous ones in several important respects. In the first place, it replaces the classical law of extinction by a more modern version which allows for incubation (enhancement) effects of exposure to CS-only stimuli, as well as for extinction effects. In the second place, the model emphasizes the importance of individual differences, and suggests precise relations between personality and the conditioning of neurotic behaviours. In the third place, the model lays stress on innate fear patterns and ‘preparedness’ as important factors in the genesis of conditioned fear responses. In the fourth place, the concept of ‘pain’ in the classical animal literature, and its use in creating models of neurosis, is supplemented by other concepts (‘frustrative non-reward’, ‘approach-avoidance’ conflict) which are more relevant to human neurosis. In the fifth place, and most important. the notion of ‘traumatic’, single-trial conditioning is abandoned, and a new theory based on incubation is proposed. It is suggested that the new theory is more adequate than previous ones to account for the known facts of human neurosis, and that it suggests novel types of experiment in both the animal and human fields which can be used to test its adequacy.  相似文献

Previous research examining the associations between decision-making styles and mental health has neglected to look at the configurations of styles. The study identifies mutually exclusive groups of people according to their combination of the five decision-making styles and examines the differences between them in mental health-related variables in two studies. In Study 1, decision-making styles, mental health indicators (well-being, depression, stress) and socio-psychological protective factors (resilience, optimism, social support) were examined in university students in two rounds 1 year apart. A cluster analysis revealed three distinct decision profiles—independent/nonintuitive, avoidant/spontaneous and rational/nonavoidant. The best values of mental health-related variables were found in the rational/nonavoidant profile and the most negative values in the avoidant/spontaneous profile. The decision-making styles were stable after 1 year although they were not able to explain changes in mental health-related variables. Study 2 identified three similar clusters in a more general sample—spontaneous/irrational, dependent/avoidant and rational/nonavoidant—with the lowest level of psychological distress symptoms in the rational/nonavoidant cluster. The study highlights the usefulness of combinations of decision-making styles with regard to mental health as well as noting their specificity according to sample characteristics.  相似文献

The study of eye movements has become popular in many fields of science. However, using the preprocessed output of an eye tracker without scrutiny can lead to low-quality or even erroneous data. For example, the sampling rate of the eye tracker influences saccadic peak velocity, while inadequate filters fail to suppress noise or introduce artifacts. Despite previously published guiding values, most filter choices still seem motivated by a trial-and-error approach, and a thorough analysis of filter effects is missing. Therefore, we developed a simple and easy-to-use saccade model that incorporates measured amplitude-velocity main sequences and produces saccades with a similar frequency content to real saccades. We also derived a velocity divergence measure to rate deviations between velocity profiles. In total, we simulated 155 saccades ranging from 0.5° to 60° and subjected them to different sampling rates, noise compositions, and various filter settings. The final goal was to compile a list with the best filter settings for each of these conditions. Replicating previous findings, we observed reduced peak velocities at lower sampling rates. However, this effect was highly non-linear over amplitudes and increasingly stronger for smaller saccades. Interpolating the data to a higher sampling rate significantly reduced this effect. We hope that our model and the velocity divergence measure will be used to provide a quickly accessible ground truth without the need for recording and manually labeling saccades. The comprehensive list of filters allows one to choose the correct filter for analyzing saccade data without resorting to trial-and-error methods.  相似文献

The ‘Three-Systems-Model’ of fear and emotion (Lang, 1968; Rachman. 1978b) is reviewed and discussed. The paper is centered on four topics relevant to such a view of fear; The definitional focus; Measurement and quantification of components; Implications for etiology; Implications for treatment of phobias. Definitional problems with the radical operationalist view implied by the Tree-Systems-Model are identified and discussed. In addition problems with measurement and quantification of the various components are discussed. Implications for etiology of phobic fears are noted. Finally, it is suggested that treatment methods be individually tailored to the particular component response-profile displayed by each patient, and that the identification of such a profile is included in standard behavioral diagnosis procedures when fear is clinically assessed.  相似文献

When a temporal delay is interposed between the contextual elements (wings) and the focal element (central axis) of the Müller-Lyer figures, the usual assimilation illusion changes to an illusion of contrast; that is, judged axis length is contrasted away from rather than assimilated toward the context provided by parallel extents between wings. Presentation time for the preceding contextual wings on the order of 1 sec or more was needed to produce contrast effects in judgments of the following focal axis (Experiment 3) and, given sufficient presentation time, these contrast effects were largely unaffected by the length of the temporal delay between contextual and focal elements, appearing equally strong for delays between 0 and 2 sec (Experiments 1 and 2). These results are consistent with a representational basis for these contrast effects that is high-level and long-lived. The Müller-Lyer contrast illusion may reflect the inadvertent error arising from basing judgments about particular objects on information about attribute differences among objects. Such judgmental errors may be the natural consequence of constrained computations that make explicit information required for certain common tasks, but at the expense of obscuring information required for less common tasks.  相似文献

Group therapists often lead consultation groups. For effective leadership it is important to distinguish between consultation groups and psychotherapy groups. A consultation group is one in which a leader serves as consultant to the members. Group process variables of task, contract, role of the leader, and effect of the larger system should be understood by the consultant. The process of defining, testing, and maintaining these variables encourages exploration of resistance and parallel process, and is an important aspect of the ongoing learning. Consultation group leaders should understand the importance of serving as group leader but not group therapist.  相似文献

ObjectivesExtensive searches for the “hot hand” have been performed in a variety of sports since the pioneering study of Gilovich, Vallone, and Tversky (1985), but empirical evidence for the existence of the effect is still fairly limited. The current review reconsiders the hot hand in sports using a meta-analytic approach.DesignMean effect size and 95% confidence interval were determined using a random effects model. Heterogeneity of the mean effect size was examined applying Cochran's Q test and the “75 percent rule”.MethodTo be included in the meta-analysis, studies had to provide an empirical investigation of the hot hand phenomenon related to sport and exercise behavior. Approximately 250 papers were located, but the final dataset included only 22 publications that met inclusion criteria, with 30 studies and 56 independent effect sizes. The articles extended over a period of twenty-seven years from 1985 until 2012.ResultsThe analysis of the effects yielded a minor positive mean effect size of .02, p = .49, using a random effects model, which is sufficient evidence for arguing against the existence of the hot hand. Due to the limited sample of studies available, only a few candidate-variables could be extracted and further examined as potential moderator variables. However, none of the considered variables had the power to explain the heterogeneity of effect sizes.ConclusionsThe present study provides additional support for Gilovich et al.'s claim that a general hot hand effect probably does not exist in sport. The scientific implications of this review for prospect advances in the field are presented and discussed.  相似文献

A semantical proof of Craig's interpolation theorem for the intuitionistic predicate logic and some intermediate prepositional logics will be given. Our proof is an extension of Henkin's method developed in [4]. It will clarify the relation between the interpolation theorem and Robinson's consistency theorem for these logics and will enable us to give a uniform way of proving the interpolation theorem for them.The results in this paper were reported at Symposium on Mathematical Logic held at Shizuoka in December 1982.  相似文献

Conclusion Brian Medlin has excluded the possibility of something being self-explanatory in anything but a logical sense. Hence any non-logical necessity has always to be in terms of something other than the explicand. In this context, the principle of sufficient reason cannot escape contraction to a form so patently useless that no proponent of the contingency argument would want to employ it. Many of the objections in Section 4 have point, however, only against an argument which uses such an unacceptable form of the principle. The objections in Section 5 are directed against an argument framed in the only other way allowable under Medlin’s dichotomy, but which is of no use to the theist, for the simple-reason that its conclusion is not existential in the required (present actuality) sense. Objections against such an argument would concern the theist only if their validity were so wide as to embrace a truly existential argument as well. As we have-seen it is in just that case that they break down. In neither Section 4 nor 5, therefore, does the article come to grips with the contingency argument. The objections leave it untouched, because neither of Medlin’s notions of contingency and necessity corresponds to that which is operative in the argument.  相似文献

A new criterion for rotation to an oblique simple structure is proposed. The results obtained are similar to that obtained by Cattell and Muerle's maxplane criterion. Since the proposed criterion is smooth it is possible to locate the local maxima using simple gradient techniques. The results of the application of the Functionplane criterion to three sets of data are given. In each case a better fit to the subjective solution was obtained using the functionplane criterion than was reported for by Hakstian for the oblimax, promax, maxplane, or the Harris-Kaiser methods.This paper is contribution No. 66 from the Program in Ecology and Evolution at the State University of New York, Stony Brook, New York. This work was supported in part by a grant (GB-20496) from the National Science Foundation. The computations were performed on an IBM 360/67 computer at the State University of New York at Stony Brook.  相似文献
