Scholars have proposed a number of courses and programs intended to improve the ethical behavior of scientists in an attempt to maintain the integrity of the scientific enterprise. In the present study, we conducted a quantitative meta-analysis based on 26 previous ethics program evaluation efforts, and the results showed that the overall effectiveness of ethics instruction was modest. The effects of ethics instruction, however, were related to a number of instructional program factors, such as course content and delivery methods, in addition to factors of the evaluation study itself, such as the field of investigator and criterion measure utilized. An examination of the characteristics contributing to the relative effectiveness of instructional programs revealed that more successful programs were conducted as seminars separate from the standard curricula rather than being embedded in existing courses. Furthermore, more successful programs were case based and interactive, and they allowed participants to learn and practice the application of real-world ethical decision-making skills. The implications of these findings for future course development and evaluation are discussed. 相似文献

Skilled (n = 12) and less skilled (n = 12) billiards players participated in 2 experiments in which the relationship between quiet eye duration, expertise, and task complexity was examined in a near and a far aiming task. Quiet eye was defined as the final fixation on the target prior to the initiation of movement. In Experiment 1, skilled performers exhibited longer fixations on the target (quiet eye) during the preparation phase of the action than their less skilled counterparts did. Quiet eye duration increased as a function of shot difficulty and was proportionally longer on successful than on unsuccessful shots for both groups of participants. In Experiment 2, participants executed shots under 3 different time-constrained conditions in which quiet eye periods were experimentally manipulated. Shorter quiet eye periods resulted in poorer performance, irrespective of participant skill level. The authors argue that quiet eye duration represents a critical period for movement programming in the aiming response. 相似文献

This article aims to reflect on the lessons learnt from using a psychodynamic approach to offering onsite therapeutic child and adolescent mental health services (CAMHS) in four pupil referral units (henceforth referred to as PRUs). The PRUs cater for six- to 16-year-old children and adolescents permanently excluded from mainstream schools. The work takes place in an inner London borough. The approach described evolved over five years through practice-based evidence of what worked well in each particular setting. This was viewed both in terms of sustaining families' engagement in the therapeutic process, and also effectively supporting child and adolescent mental health services and education staff in their respective tasks. The model which gradually evolved owes much to Bion's concept of containment as the necessary foundation for emotional growth and genuine learning. It also draws on ideas from psychoanalytic consultation and open systems theory. The importance of work discussion groups in this setting will also be evident. Some links are made to relevant Buddhist concepts and metaphors. 相似文献

Although the effects of ageing on human information processing and performance have been studied extensively, many fundamental questions about cognitive ageing remain to be answered definitively. For example, what are the sources of age-related slowing? How much is working-memory capacity reduced in older adults? Is time-sharing ability lost with age? Answering such questions requires a unified computational theory that characterises the interactive operations of many component mental processes and integrates diverse data on cognitive ageing. Toward fulfilling this requirement, an executive-process interactive control (EPIC) architecture has been extended to model performance of both young and older adults. EPIC models yield accurate accounts of ageing effects on reaction times and accuracy in basic dual-task and working-memory paradigms. From these accounts, it appears that time-sharing ability and working-memory capacity decrease relatively little until after 70 years of age. Before age 70, at least some apparent performance decrements may be attributable to conservative executive processes and inefficient task procedures rather than decreased "hardware" functionality. By clarifying and deepening such insights, unified computational theories like EPIC will help answer many questions about cognitive ageing. 相似文献

The experiences people have over the course of their careers are commonly held to contribute to creative achievement. In this study, an attempt was made to identify the career events contributing to creative achievement in the sciences. Prior theoretical and empirical work was used to identify relevant career events in the areas of education, domain exposure, mentoring, adversity, work procedures, collaboration, laboratory leadership, and organizational influences. Obituaries were obtained for 499 scientists working in multiple fields in the social, physical, life, and health sciences and were used to assess whether these events were evident in scientists' careers. Comparisons of high achieving and low achieving scientists with regard to these events indicated that multiple events lying in each of these general areas contributed to career achievement. The nature of the events yielding significant differences were discussed regarding their implications for the development of creative potential in scientific fields. 相似文献

Objective: Perceived variety represents a psychosocial experience that gives rise to, and supports the maintenance of, an individual’s well-being. In this study, we developed an instrument to measure perceived variety in exercise (PVE), and examined whether ratings of PVE predict unique variance in indices of exercise-related well-being in addition to that explained by satisfaction of the three basic psychological needs (for competence, relatedness and autonomy) embedded within self-determination theory (SDT). We also examined the extent to which variance in perceived variety is empirically distinct from (or subsumed by) competence, relatedness and autonomy in the context of exercise.Methods: A convenience sample of community adults (N?=?507) completed online surveys twice over a six-week period (n?=?367).Results: PVE was found to prospectively predict unique variance in indices of exercise-related well-being, in addition to that explained by perceived competence, relatedness and autonomy. Using exploratory and confirmatory factor analytic procedures, perceived variety was found to be empirically distinct from perceived competence, relatedness and autonomy.Conclusion: Results from this work suggest that perceived variety holds potential for theoretical and applied advancements in understanding and predicting well-being in exercise settings. 相似文献

Compulsive sexual behavior (CSB) is defined as difficulties in controlling inappropriate or excessive sexual fantasies, urges, or behaviors that cause subjective distress or impairment in important areas of daily functioning. Using data from a baseline telephone interview, we examined the prevalence of CSB in a convenience sample of 820 postdeployed U.S. military male and female veterans and investigated correlates of CSB with sociodemographics and other mental health and sexual history characteristics. More men (13.8%) than women (4.3%) endorsed CSB-related symptoms. Given the limited sample size of women reporting CSB, correlational analyses were conducted only with men. After adjusting for significant sociodemographics, results indicated that gambling, suicidality, and sexually transmitted infections were significantly associated with male CSB. Current results suggest that CSB may be prevalent among U.S. military veterans post deployment and associated with significant negative health indices in men. CSB warrants attention regarding screening and intervention. 相似文献

Abstract Simulated tennis playing situations were created for the laboratory testing of visual search patterns, anticipation, reactions, and movements to compare male and female high-level and beginning players. Of particular interest was the degree to which each measure would differentiate the groups. Participants were highly-rated university players (N-30) and students enrolled in a beginning tennis class (N = 30). Under one testing condition, visual search patterns were recorded as they viewed filmed opponents serve (60 trials) and hit ground strokes (60 trials). Also recorded was anticipation accuracy and speed of the intended type and location of serves and the intended placement of ground strokes. In other testing, execution of a split step was followed by moving rapidly to the comet location for a simulated stroke in response to a series of light cues. Reaction and movement times were recorded. Discrimination analysis revealed that experts and beginners were most differentiated due to fixations on certain cues and predicting ball direction. As to visual search analysis of fixation duration for nine possible areas during the serves, only the head area was significant. Beginners directed more time toward the head region than did the highly skilled. Experts and novices had similar visual patterns with respect to ground strokes, and a few differences existed within the two female groups, in the two male groups. as well as between males and females. Anticipation measures for the serve indicated that experts were faster and more accurate than beginners, and males were faster than females. Ground stroke data revealed that the highly-skilled were faster and more accurate than novices. Finally, the simulated split-step data showed that reaction times and movement times were faster for the experts versus the beginners, and males were quicker in movement times than females. 相似文献
