The present study attempted to examine the changes associated with learning two time-constrained aiming movements at the neuromuscular and behavioral levels of analysis. Electromyographic data and movement kinematics were used to assess changes due to practice. Eight right-handed females were required to perform a 45° horizontal forearm extension in either 200 ms or 500 ms for 100 trials on each of four consecutive days. Both groups demonstrated an improvement in performance and a decrease in within-subject variability in the endpoint response measures, movement trajectory, and myoelectric pattern. With practice, there was a decrease in the amount of cocontraction between the agonist and antagonist muscles during movement execution, which indicated an elimination of unwanted neural activity. For the 200 ms task, the acceleration profile became symmetrical and a triphasic myoelectric pattern became evident. The deceleratory phase of the 500 ms task was longer than the acceleratory phase, and a biphasic pattern became apparent. The results suggest that two different control strategies were developed in the execution of the two movements examined. In addition, the relative invariance of the spatial-temporal dependent measures, as compared to the variability of the EMG, led us to the conclusion that the movement planning hierarchy was concerned with the spatial-temporal domain, whereas the amplitude and timing of muscular activity were planned at a lower level and thus played a subordinate role in movement production. 相似文献

The purpose of this study was to examine the effects that differentially coded (black and white and color) illustrations had on students (N = 117) who were classified as field dependent, field neutral, or field independent as a result of their performance on the visually oriented Group Embedded Figures Test (Witkin, Olt-man, Rashin, & Karp, 1971). Students were randomly assigned to two instructional treatments complemented by illustrations (black and white and colored). After receiving their respective treatments, students reviewed two visually oriented criterion tests. Two-way analyses of variance conducted on achievement scores indicated that field independents scored significantly higher than did field dependents on both visual tests, and differences between field-dependent and field-independent learners who received the color-coded treatments on the visual identification test were insignificant. Results indicate that field dependency is an important instructional variable and that for some types of learning objectives the process of color coding instructional materials may reduce achievement differences attributed to differences in cognitive style. 相似文献

The evaluation of a person seeking or volunteering information in cooperatively or competitively oriented problem solving groups was investigated in 63 white and black, male and female, high school and college students. It was hypothesized that under cooperative conditions the seeking of information would be evaluated more positively than would the volunteering of information, while under competitive conditions the volunteering of information would be evaluated more positively than would the seeking of information. A highly trained confederate (C) engaged in either the seeking of information or the volunteering of information in four-person problem solving groups in which Ss were either cooperatively or competitively oriented. Ss rated Cs on eight bipolar scales. The results confirmed the hypothesis. 相似文献

College student-athletes tend to consume more alcohol, engage in sex, and report more sex partners than nonathlete students. The current study examined the relationship between religiosity (e.g., influence of religious beliefs and church attendance) and alcohol use and sex behavior among college student-athletes. Most of the student-athletes (n = 83) were religious. Influence of religious beliefs was a significant predictor of less alcohol use and less sexual activity (i.e., oral and vaginal sex, number of sex partners). However, increased church attendance was not found to be a protective factor. Findings suggest that religious beliefs may contribute to reduction of alcohol use and sexual risk among college student-athletes. Consideration should be given to incorporating religiosity aspects in sexual and alcohol risk-reduction interventions for student-athletes. 相似文献

ABSTRACT This paper examines the commercialization of an alternative youth subculture. Sociologists have typically focused on the ways that authorities have attempted to repress and censor youthful rebellion, but less attention has been given to their appropriation by mass media and consumer markets. In fact, I argue that condemnation by authorities has often made deviance more alluring for some young people, while commercialization appears to dilute the adversarial qualities of youth culture. I use the concept “subcultural capital” to explain both the economic value of youthful rebellion and the process of co-optation that occurs when it is absorbed into the consumer culture. While labeling and other disciplinary forms of societal reaction have attempted to enforce the boundary between deviance and normality, commercialization can have the opposite effect of conflating these boundaries. 相似文献

What has been the historical relationship between set theory and logic? On the óne hand, Zermelo and other mathematicians developed set theory as a Hilbert-style axiomatic system. On the other hand, set theory influenced logic by suggesting to Schröder, Löwenheim and others the use of infinitely long expressions. The question of which logic was appropriate for set theory — first-order logic, second-order logic, or an infinitary logic — culminated in a vigorous exchange between Zermelo and Gödel around 1930. 相似文献

Abstract The aim of this survey of 472 adult women was to assess women patients' feelings about intimate examinations and their perceptions and experiences of sexually inappropriate medical practice. Two-thirds of women preferred a women doctor for intimate examinations. Slightly more than two-thirds found intimate examinations embarrassing and stressful, and strongly expressed the need for information and on-task, health-related comments during these examinations. General personal comments or non-medical touching were not particularly welcomed, even for the purpose of comforting the patient. There was a range of views about patients' personal relationships with doctors, with the lines between acceptable and unacceptable behaviour somewhat ambiguous. A small but significant number of women perceived that they had been sexually harassed (5%) or abused (3%) by a doctor, with this experience more common for non-English speaking women. Results were discussed in terms of implications for improved doctor practice, particularly during intimate examinations and with vulnerable patients. 相似文献
