Fourteen female subjects were tested during the menstrual (days 1–4), follicular (days 6–12), luteal (days 17–21), and premenstrual (days 23–27) phases of their menstrual cycles. Of the tests used (arm-hand steadiness, galvanic skin response to an auditory stimulus, reaction time - simple and choice, time estimation, and digit-symbol substitution), only arm-hand steadiness showed statistically significant fluctuations over the course of the cycle. Daily self-ratings of various symptoms and moods showed no significant changes when the appropriate statistical techniques were used; parametric techniques suggested fluctuations in reports of pain, bloatedness, hunger, hours of sleep, and pressure of immediate academic work. 相似文献

Two experiments were conducted using a multiple-item list in which each item consisted of a pair of pictures. The model indicated which member of each pair she preferred and was either positively reinforced, negatively reinforced, or received neutral consequences. The S then indicated his preferences (imitation test). Following the imitation test, each S was asked to recall the model's choices. Age was an independent variable in both experiments. Imitation scores of the children, preschool to sixth-grade age range, were strongly influenced by differential vicarious reinforcement. Vicarious reward increased imitation and vicarious punishment decreased it. College students' imitation scores were only minimally influenced by differential vicarious reinforcement. Within- and between-subjects variations of vicarious reinforcement had similar effects. Recall scores were surprisingly high and were not significantly influenced by differential vicarious reinforcement. Interestingly, age and percentage of correct recall were negatively correlated. 相似文献

Four prominent oblique transformation techniques—promax, the Harris-Kaiser procedure, biquartimin, and direct oblimin—are examined and compared. Additionally, two newly-developed procedures, falling into the category designated as Case III by Harris and Kaiser [1964], are presented and included in the comparisons. The techniques are compared in light of their freedom from bias in the interfactor correlations, and their ability to yield clear simple structures, over many data sets—some constructed and some real—varying widely in terms of number of variables and factors, factorial complexity, and clarity of the hyperplanes. Results are discussed, and implications for practice are noted. 相似文献

Previous studies have failed to find support for the hypothesis, derived from Level of Aspiration Theory, that individuals chose to date those whose “social desirability” level is similar to their own. In the present experiments, which were designed to test the matching hypothesis, the salience of possible rejection by the dating choice was varied. Both experiments found support for the principle of matching in social choice. This support was obtained, however, not just under conditions in which rejection was presumably salient but for all conditions of choice. This and additional findings were discussed. 相似文献

The purpose of this study was to compare four measures of difficulty of mental multiplication items: percentage of pupillary dilation, latency of solution, number of correct responses, and judgment of item difficulty. Sixteen multiplication problems, classified into four levels of difficulty, were presented visually to 13 Ss, who verbalized their solutions to the problems. Analyses of variance and correlation coefficients were computed. It was concluded that all four measures of difficulty were useful but that judgment of difficulty and latency of solution were better measures of item difficulty than were the other two. A discussion of pupillary dilation and information processing is included. 相似文献

In order to investigate the potential difficulties posed by task demands and by surface features of metaphorical sentences, children aged 6, 7, and 9 years were presented with metaphorical grounds encoded in five alternative linguistic forms: predicative metaphors, topicless metaphors, similes, analogies, and riddles. The task demands posed by comprehension of predicative metaphors proved greater than those posed by topicless metaphors, suggesting that it is more difficult to specify the similarity between two given terms than it is to generate a missing term. When topicless metaphors were rewritten either in an explicit analogic form or in the form of a riddle, comprehension was increased; however, when predicative metaphors were rewritten as similies, the addition of the term “like” to make clear the similarity relationship between the two terms failed to elevate understanding. 相似文献

Data from a longitudinal study of postbaccalaureate nursing careers are discussed in the context of the motive-to-avoid-success controversy. Two groups of nurses with continuous work histories were intensively studied. While most had experienced upward professional mobility, a significant minority had lateral careers, which, though not characterized by advancement, typically provide rewards of intensification. Further, lateral careers only occurred in specialties allowing a high degree of professional autonomy. Thus, upward mobility and advancement should not be the sole criteria of women's occupational progress. Alternative conceptions of success may be significant in many occupations, although such beliefs may not serve as viable substitutes for professional autonomy and the opportunity for personal development. Lateral movement may also characterize most men's work lives more aptly than descent or ascent; hence the findings underscore the necessity to rethink the image of movement in both male and female work spheres.The research upon which this paper is based was supported by a grant from the Nursing Resources Division, USPHS (Grant NU-004-94-03) for the study of Post-Baccalaureate Careers in Nursing, Fred Davis and Virginia Olesen, Principal Investigators, Ellen Lewin, Assistant Project Director. This article was originally presented as a paper at the Pacific Sociological Association meetings, Sacramento, California, April 1977, where the panel commentator, Sheryl Ruzek, provided useful comments on the essay. Jane Tabata Usami provided a very helpful bibliographic search and other technical assistance. 相似文献
