Ås, A. Non-hypnotic experiences related to hypnotizability in male and female college students. Scand. J. Psychol ., 1962, 3 , 112–131.—Some recent research on the relation between subjective experiences and hypnotic susceptibility is reviewed. In a male sample of 50 subjects significant correlations between scores on the Experience Inventory and hypnotizability were found. A cross-validation of composite experience scores on this sample and a female sample studied earlier gave positive results. Based on several sources of data a preliminary analysis is made of the similarities and differences between male and female students regarding experiences related to hypnotizability. 相似文献

Conclusion The influence of mental health upon the perception, assimilation, and expression of religious values is very apparent. As the precision of our knowledge increases, there is no lack of evidence for an affirmative answer to the question posed for the second part of this report.If the proper methods for studying the influence of religion on mental health have seemed to us to be full of ambiguity, it has also seemed to us that the future development of our scientific knowledge relative to the influence of mental health upon religion is entirely feasible and highly desirable.To work for better mental health is to permit believers (and this is equally valid for all religions and all faiths) to gain better understanding of the call of their religion in all its authenticity. The very perception of the religious message, in its richness and complexity, would be enhanced if one could raise the level of balance and of psychological maturity in a population. Mental health does not automatically make men more religious (we have no interest in an automatic, conditioned religion), but it prepares a better background in which the word of God may be heard, received, and more fully assimilated.It is in this perspective that we all must work together—doctors, psychologists, educators, priests—toward improvement of mental health. Let us, however, avoid unenlightened enthusiasm; let us keep ourselves from undertakings of which the practical applications would be directed toward illusory purposes. An effective program demands precise objects: these can be formulated only on the basis of methodically conducted research and scientifically established conclusions. 相似文献

In this paper a method is outlined for measuring the diversity of the results of applied R&D with the use of IPC (International
Patent Classification). The method has been tested in the contexts of the academic physical, engineering, and chemical institutes.
The trend of applied research at a given institute increases both at the level of classes and subclasses, and at the IPC level.
Inventions developed within specializations at each institute have a greater efficiency than other forms of inventive activity.
The objective was to seek the optimal extent of diversification of applied R&D, which would simultaneously ensure the preservation
of the scientific specialization of an institute, the high level of scientific research associated with developing innovations,
and the high overall efficiency of each institute. 相似文献

Finland has followed the Scandinavian model of the welfare state in which the level of state activism is high, the economic
pressures on the scientific activities are strong, and the left-wing parties and the Center Party have formulated the main
ideas. In the 1970s welfare ideology was adopted in science policy by emphasizing the promotion of socially relevant scientific
activities and the expansion of the university system as a means of effecting equal opportunity. Currently, the trend is toward
a mixed welfare economy. Programs have been prepared in spite of the radical cut in government expenditure, and without a
consideration of the long-term consequences. 相似文献

When an observer views a moving scene binocularly, both motion parallax and binocular disparity provide depth information. In Experiments lA-1C, we measured sensitivity to surface curvature when these depth cues were available either individually or simultaneously. When the depth cues yielded comparable sensitivity to surface curvature, we found that curvature detection was easier with the cues present simultaneously, rather than individually. For 2 of the 6 subjects, this effect was stronger when the component of frontal translation of the surface was vertical, rather than horizontal. No such anisotropy was found for the 4 other subjects. If a moving object is observed binocularly, the patterns of optic flow are different on the left and right retinae. We have suggested elsewhere (Cornilleau-Pérès & Droulez, in press) that this motion disparity might be used as avisual cue for the perception of a 3-D structure. Our model consisted in deriving binocular disparity from the left and right distributions of vertical velocities, rather than from luminous intensities, as has been done in classical studies on stereoscopic vision. The model led to some predictions concerning the detection of surface curvature from motion disparity in the presence or absence of intensity-based disparity (classically termedbinocular disparity). In a second set of experiments, we attempted to test these predictions, and we failed to validate our theoretical scheme from a physiological point of view. 相似文献

Paradigmatic complexes in family psychotherapy have been indicating a revolutionary change and the creation of new paradigms for the past thirty years. Starting with the application of the general systems theory and the development of those concepts that have been emerging regarding psychosomatic illnesses we discuss the epistemological confusion created, the methodological problems and the dissociation between theory and practice. We suggest a double process of investigation of the family structure using a knowledge of the basic attitudes and the development of a psychotherapy programme within the family of the psychosomatic patient. 相似文献

Recently, several studies have addressed the question of whether depression affects priming in implicit memory tasks. The main aim of this experiment was to assess the presence of a bias for negative information in explicit memory (free recall) and implicit memory (word-stem completion) tasks among subclinically depressed subjects compared to nondepressed subjects, using the typical levels of processing manipulation. The results of this study show the existence of a mood-congruent memory bias for both implicit and explicit memory in depressed subjects. The theoretical implications of these findings for implicit and explicit memory biases associated with depressed mood are discussed. 相似文献

In this review, we consider three possible criteria by which knowledge might be regarded as implicit or inaccessible: It might be implicit only in the sense that it is difficult to articulate freely, or it might be implicit according to either an objective threshold or a subjective threshold. We evaluate evidence for these criteria in relation to artificial grammar learning, the control of complex systems, and sequence learning, respectively. We argue that the convincing evidence is not yet in, but construing the implicit nature of implicit learning in terms of a subjective threshold is most likely to prove fruitful for future research. Furthermore, the subjective threshold criterion may demarcate qualitatively different types of knowledge. We argue that (1) implicit, rather than explicit, knowledge is often relatively inflexible in transfer to different domains, (2) implicit, rather than explicit, learning occurs when attention is focused on specific items and not underlying rules, and (3) implicit learning and the resulting knowledge are often relatively robust. 相似文献
