In a factorial design, athletic involvement (no varsity sport, varsity noncontact sport, varsity contact sport) was varied with induced disposition (unprovoked, provoked). Under conditions of no provocation, no significant differences in aggressiveness were observed between nonathletes and athletes, nor between noncontact- and contact-sport athletes. In contrast, under conditions of provocation, nonathletes displayed more aggressiveness than athletes. Non-contact-sport athletes behaved significantly less aggressively than both nonathletes and contact-sport athletes. Contact-sport athletes failed to behave significantly less aggressively than nonathletes, however. The findings were explained as the result of an acquired superior ability in athletes to cope with provocation under competitive circumstances, which is partially counteracted in contact-sport athletes by their aggressiveness habits and disinhibition training. 相似文献

Data are presented for 16 reversible and 9 ambiguous figures on measures of latency and duration of the initial response and total number of fluctuations during a 30-sec interval by 42 Ss. Of particular interest are the magnitudes, correlations, and factor analysis of eight widely used figures (e.g., Necker cube). The methodological advantages, theoretical ambiguities, and further research possibilities of this information are discussed. 相似文献

The present experiment examined the influence of repetition on iconic memory using the Sperling (1960) procedure. It was assumed that the whole-report procedure would estimate only information available from a somewhat more permanent memory system than the icon, while the partial report would estimate both that information and the information available in the icon. The difference between the whole and partial report was assumed to measure information available only in the icon. Across a series of 160 displays one particular display occurred half the time (80 repetitions). The results indicated that the repetition influenced recall from the more permanent memory system assessed by whole report, but had no influence on the information available from the icon (partial report minus whole report). 相似文献

The interpretations of certain critical terms or concepts frequently occurring in counseling interviews were compared by means of the semantic differential technique for NDEA Counseling and Guidance Institute members and high school boys and girls. 11 of 30 F tests were significant. Counselors generally rated those concepts reflecting adult values or planning for the future (e.g., parents, counseling, studying, aptitude test) as more valuable and more active than did students. The activity dimension proved to be most sensitive in differentiating between the “sets” of the counselors and students. Counselors, possibly because of greater involvement, consistently perceived more activity in the various concepts than did students. Limitations of the study and suggestions for future research are noted. 相似文献

The analysis of proximities: Multidimensional scaling with an unknown distance function. I. 总被引:3,自引:0,他引:3
Roger N. Shepard 《Psychometrika》1962,27(2):125-140
A computer program is described that is designed to reconstruct the metric configuration of a set of points in Euclidean space on the basis of essentially nonmetric information about that configuration. A minimum set of Cartesian coordinates for the points is determined when the only available information specifies for each pair of those points—not the distance between them—but some unknown, fixed monotonic function of that distance. The program is proposed as a tool for reductively analyzing several types of psychological data, particularly measures of interstimulus similarity or confusability, by making explicit the multidimensional structure underlying such data. 相似文献

Hierarchical clustering schemes 总被引:74,自引:0,他引:74
Stephen C. Johnson 《Psychometrika》1967,32(3):241-254
Techniques for partitioning objects into optimally homogeneous groups on the basis of empirical measures of similarity among those objects have received increasing attention in several different fields. This paper develops a useful correspondence between any hierarchical system of such clusters, and a particular type of distance measure. The correspondence gives rise to two methods of clustering that are computationally rapid and invariant under monotonic transformations of the data. In an explicitly defined sense, one method forms clusters that are optimally connected, while the other forms clusters that are optimally compact.I am indebted to R. N. Shepard and J. D. Carroll for many stimulating discussions about this work, and for aid in preparing this paper. 相似文献
