Consistent application of dialectical materialism leads Marxism-Leninism to the assertion that matter is infinite in its properties. However, the history of physics shows that the various levels of matter possess geometric dimensions that originate at the lowest level and continue through the others. The search for absolute natural constants — which Planck called the most pleasant task of physics — shows the conviction of the physicists that there is a limit to the parameters, a limit beyond which matter is no longer divisible.

1373 psychology students from Barcelona (Spain), Liège (Belgium), Lille (France), Mexico city (Mexico) and Montréal (Canada) responded to a questionnaire dealing with their image of the discipline at various points in their university career. The students were asked to designate the authors they felt to be the most important as well as their preferences in regard to various areas and tendencies in psychology. The results show more agreement than could have been expected considering the cultural diversity and the great distance among the groups examined. Relevant differences from the other universities studied were found only with the Mexican students. 相似文献

Although Islam is the fastest growing religion worldwide, only few studies have investigated body image in Muslim women, and no study has investigated body checking. Therefore, the present study examined whether body image, body checking, and disordered eating differ between veiled and unveiled Muslim women, Christian women, and atheist women. While the groups did not differ regarding body dissatisfaction, unveiled Muslim women reported more checking than veiled Muslim and Christian women, and higher bulimia scores than Christian. Thus, prevention against eating disorders should integrate all women, irrespective of religious affiliation or veiling, with a particular focus on unveiled Muslim women. 相似文献

This is a companion to a paper by the authors entitled “Gödel on deduction”, which examined the links between some philosophical views ascribed to Gödel and general proof theory. When writing that other paper, the authors were not acquainted with a system of natural deduction that Gödel presented with the help of Gentzen’s sequents, which amounts to Ja?kowski’s natural deduction system of 1934, and which may be found in Gödel’s unpublished notes for the elementary logic course he gave in 1939 at the University of Notre Dame. Here one finds a presentation of this system of Gödel accompanied by a brief reexamination in the light of the notes of some points concerning his interest in sequents made in the preceding paper. This is preceded by a brief summary of Gödel’s Notre Dame course, and is followed by comments concerning Gödel’s natural deduction system. 相似文献

An influential account of how cognitive control deals with conflicting sources of information holds that conflict is monitored
by a module that automatically recruits attention to resolve the conflict. This leads to reduced effects of conflict on the
subsequent trial, a phenomenon termed conflict adaptation. A prominent question is whether control processes are domain specific—that is, recruited only by the particular type of
conflict they resolve. Previous studies that have examined this question used two-choice tasks in which feature repetition
effects could be responsible for domain-specific adaptation effects. We report two experiments using four-choice (Experiment
1) and five-choice (Experiment 2) tasks that contain two types of irrelevant sources of potentially conflicting information: stimulus location (Simon conflict)
and distractors (flanker conflict). In both experiments, we found within-type conflict adaptation for both types of conflict
after eliminating trials on which stimulus features were repeated from one trial to the next. Across-type conflict adaptation,
however, was not significant. Thus, conflict adaptation was due to domain-specific recruitment of cognitive control. Our results
add converging evidence to the idea that multiple independent control processes are involved in reactive cognitive control,
although whether control is always local remains to be determined. 相似文献

Semantic memory is the subsystem of human memory that stores knowledge of concepts or meanings, as opposed to life-specific experiences. How humans organize semantic information remains poorly understood. In an effort to better understand this issue, we conducted a verbal fluency experiment on 200 participants with the aim of inferring and representing the conceptual storage structure of the natural category of animals as a network. This was done by formulating a statistical framework for co-occurring concepts that aims to infer significant concept-concept associations and represent them as a graph. The resulting network was analyzed and enriched by means of a missing links recovery criterion based on modularity. Both network models were compared to a thresholded co-occurrence approach. They were evaluated using a random subset of verbal fluency tests and comparing the network outcomes (linked pairs are clustering transitions and disconnected pairs are switching transitions) to the outcomes of two expert human raters. Results show that the network models proposed in this study overcome a thresholded co-occurrence approach, and their outcomes are in high agreement with human evaluations. Finally, the interplay between conceptual structure and retrieval mechanisms is discussed. 相似文献

Participants performed a free-throw shooting task and a grip-strength task before and after imagery, nonspecific arousal, or no instructions. Imagery improved performance in the free-throw shooting task, which is assumed to have more cognitive components than the grip-strength task. Imagery did not improve performance in the grip-strength task, which is assumed to have fewer cognitive components than the free-throw task. Nonspecific arousal, on the other hand, improved performance in the grip-strength task but not in the free-throw shooting task. Athletic experience, confidence levels, and gender were correlated with actual performance levels in both tasks, but not with improvement. Results are discussed within the transfer-appropriate processing framework. 相似文献
