Several of the more popular statistics texts used in psychology are reviewed with respect to their treatment of the measurement and interpretation of skewness. Some areas in psychology where measures of skewness of distributions may yield significant information are indicated. Tables of 1%, 2% and 5% points of moment measures of skewness and tables of the 1% and 5% points of the difference in skewness of two uncorrelated distributions are presented. These tables are approximations based on the approximate normality of skewness in large samples from normal populations. The limited confidence with which these tables can be used in the absence of exact knowledge of the distribution function of the underlying statistics is indicated.The opinions expressed in this article are those of the author and are not to be interpreted as official War Department policy. 相似文献

The subjects in these experiments were 132 children, varying in age from 4 to 7 years. These experiments were designed to assess the efficacy of various multiple scheduling procedures in producing reliable stimulus control. The schedules studied were multiple fixed-ratio-extinction (mult FR EXT); multiple differential-reinforcement-of-other-behavior-fixed-ratio (mult DRO FR); multiple differential-reinforcement-for-low-rate-fixed-ratio (mult DRL FR); and multiple fixed-interval-fixed-ratio (mult FI FR). In addition other techniques were investigated, such as presenting FR's in blocks; increasing the size of the FR's; attaching a DRL to the FI members; temporarily shifting to new schedules; and adding an external clock to the FI's. These experiments yielded the following results.1.) Strong stimulus control was produced by mult FR EXT, mult DRO FR, and mult DRL FR schedules. Control for mult FR EXT was mediated principally by the individual stimuli, though on occasion it was dependent in part on the change of stimuli. The mult DRO FR was found to be highly useful for those children who had very high initial rates or who were generally uncooperative and unmanageable.2.) Contrary to a previous finding, some subjects were brought under stimulus control by means of mult FI FR schedules without the aid of additional procedures. Most, however, were not. Additional techniques found to augment the development of mult FI FR control included: (1) presenting FR's in blocks; (2) increasing the size of the FR's; (3) attaching a DRL to the FI component for a time and later removing it; and (4) shifting to a mult DRL FR, developing control, and then returning to the original mult FI FR.3.) Addition of an external clock to the FI components of the mult FI FR had several effects. Strongest control, including well-developed acceleratory patterns during the FI's, was developed in those subjects who had first been shifted from a regular mult FI FR to a mult FR EXT, brought under control, and then returned to the mult FI FR with the clock added. The added clock also produced strong control if it was present when the subject was first begun on a mult FI FR schedule. In some cases, the addition of the clock produced control in subjects who had not been controlled previously by the regular mult FI FR, but these were always subjects who had high rates. The addition of the clock first lowered the rate, then produced control. 相似文献

This study examined the validity of situational view on culture‐specific behaviours focusing on self‐evaluation. Two experiments with American students as samples were conducted to examine whether priming their self‐construals would affect individuals' self‐evaluation. In Experiment 1, the participants' self‐evaluation was compared across different conditions of primed self‐contruals. In Experiment 2, the participants were split into 2 groups based on their initial default self‐consturals and, the self‐evaluations were compared across the 2 groups after priming self‐contruals. The results demonstrated that although the participants' self‐evaluation was initially in accord with their default self‐construal, it changed into accord with the primed self‐construals. The findings supported the proposed cultural game player view. Implications on situational view of self‐evaluation are also discussed. 相似文献

According to proponents of one influential account of metaphysical naturalness, properties fall along a spectrum from perfectly natural to highly non-natural. The perfectly natural end of the spectrum is occupied by properties that appear in the laws of nature, account for resemblance and causal powers, and ground other properties, whereas the highly non-natural properties at the spectrum’s other end are not like this at all. However, there is another phenomenon that looks very much like metaphysical naturalness but is context-dependent. I call this phenomenon context-dependent naturalness. In this paper I describe two cases in which inappropriate use is made of metaphysical naturalness and argue that in such cases, the context-dependent importance of certain properties has been confused for the context-independent importance of those properties. I argue that in order to avoid such problems we should embrace context-dependent naturalness. 相似文献

Each of the major engineering societies has its own code of ethics. Seven “common core” clauses and several code-specific clauses can be identified. The paper articulates objections to and rationales for two clauses that raise controversy: do engineers have a duty (a) to provide pro bono services and/or speak out on major issues, and (b) to associate only with reputable individuals and organizations? This latter “association clause” can be justified by the “proclamative principle,” an alternative to Kant’s universalizability requirement. At the heart of engineering codes of ethics, and implicit in what it is to be a moral agent, the “proclamative principle” asserts that one’s life should proclaim one’s moral stances (one’s values, principles, perceptions, etc.). More specifically, it directs engineers to strive to insure that their actions, thoughts, and relationships be fit to offer to their communities as part of the body of moral precedents for how to be an engineer. Understanding codes of ethics as reflections of this principle casts light both on how to apply the codes and on the distinction between private and professional morality. 相似文献

Entrepreneurial intuition is the affectively charged recognition and evaluation of a business venturing opportunity arising as a result of involuntary, rapid, non-conscious, associative processing. This article integrates theories of dual-processing and models of the business venturing (opportunity recognition, evaluation, and exploitation) in a model of entrepreneurial intuition, which links intuitive expertise, cognitive style, somatic state, and the affect heuristic with System 2 interventions and the contingencies of the decision environment. Six research propositions are offered with suggestions for how they can be tested. The theoretical and practical implications of entrepreneurial intuition are discussed in terms of the unfolding of a research agenda relating to this important but under-theorized and under-researched construct in work and organizational psychology. 相似文献
