时-空整合影响图形识别的眼动研究 总被引:2,自引:1,他引:2
采用眼动追踪的方法对在不同方向(上、下、左与右)及距离(2.0°‘和4.0°视角)上先后出现的特征组合不同的图形识别过程进行了研究。结果表明。首先,对由不同颜色和形状构成的图形的识别受到图形特征组合的影响,视觉系统对颜色和形状的加工存在明显差异,与颜色加工相比,视觉系统需要更多的时间才能完成形状识别。此外,虽然图形识别的速度和准确性受运动方向与距离的影响较小,但在不同运动方向和距离上,视觉系统是通过改变眼动的时间和空间特性来完成识别任务的,视觉系统在识别过程中的这种时间与空间的整合特点还有待于进一步研究。 相似文献

The effectiveness of retrieval practice for aiding long-term memory, referred to as the testing effect, has been widely demonstrated. However, the specific neurocognitive mechanisms underlying this phenomenon remain unclear. In the present study, we sought to explore the role of pre-retrieval processes at initial testing on later recognition performance by using event-related potentials (ERPs). Subjects studied two lists of words (Chinese characters) and then performed a recognition task or a source memory task, or restudied the word lists. At the end of the experiment, subjects received a final recognition test based on the remember–know paradigm. Behaviorally, initial testing (active retrieval) enhanced memory retention relative to restudying (passive retrieval). The retrieval mode at initial testing was indexed by more positive-going ERPs for unstudied items in the active-retrieval tasks than in passive retrieval from 300 to 900 ms. Follow-up analyses showed that the magnitude of the early ERP retrieval mode effect (300–500 ms) was predictive of the behavioral testing effect later on. In addition, the ERPs for correctly rejected new items during initial testing differed between the two active-retrieval tasks from 500 to 900 ms, and this ERP retrieval orientation effect predicted differential behavioral testing gains between the two active-retrieval conditions. Our findings confirm that initial testing promotes later retrieval relative to restudying, and they further suggest that adopting pre-retrieval processing in the forms of retrieval mode and retrieval orientation might contribute to these memory enhancements. 相似文献

Together with the completion of the Human Genome Project, biomedical research has marched into the "Post-Genomic Era." In order to take advantage of this extracted gene related information extensively and precisely so as to realize man's biological phenomena as well as the mechanism of pathogenesis, consequentially, a large scale sample collection of different geological areas and/or ethnic groups becomes necessary for the future population based genetic research of a country and, in turn, the construction of population-based genetic database (Biobank). In recent years, both mainland China and Taiwan have not only made great progress in information and computation technologies, but have also gradually taken a close look into the quality of medicine delivery. Thus, it becomes unavoidable for both sides to create each one's population-based genetic databases (Biobank). Theoretically speaking, the Biobank development shall benefit the study on the correlation between genes and disease and also the solution for disease treatment as well. At the same time, medical diagnostic technology has also been significantly improved. It is believable that the population-based genetic database might be utilized to promote medical quality and to reduce the cost of public health delivery. Further; in the near future, it might become the "raw materials "for medical research application. However when taking promotion of public welfare as the premises for a Biobank development, the severe and multi challenge occurred against the traditional legal rules in terms of the privacy protection, public trust development, the compliance of informed consent principle, the implementation of benefit-sharing doctrine and the possible discrimination concern about the population/participants selection and some other ELSI issues. In this paper, the major legal issues encountered by the Biobank development will first be reviewed accompanied by the background information concerning the Biobank development scenario crossing the Taiwan Strait. Also, mainly following the realm of comparative policy or legal approaches, the paper learning from the fruits of this comparative study, tries to propose some recommendations for future legislative consideration by both mainland China and Taiwan. It's been this author's wish that, when establishing a large scale population based Biobank, the promotion of public trust shall be placed as the primary goal together with the emphasis on supporting publicity and transparency on the administrative practices, so as to encourage the public participation in observing the principle of altruism and, in turn, benefit the future biomedicine development. 相似文献

We propose and meta-analytically test a theoretical model of individual and job-based predictors of change-oriented behaviors. Meta-analytic tests (106 effect sizes, N = 28,402) demonstrate that employee's proactive personality is a stronger predictor of change-oriented behavior than the five-factor model (FFM) personality traits of openness and extraversion. Also, enriched job characteristics (autonomy, complexity, and task significance) are more important in predicting change-oriented behavior, than un-enriched job characteristics (routinization and formalization). Finally, we establish work engagement as a mediator that provides an explanation for how and why proactive personality and enriched job characteristics predict change-oriented behavior. We provide both theoretical and empirical integration of the literature with practical implications for managing change-oriented behaviors, which are increasingly recognized as important to both organizational effectiveness and employee career management. 相似文献

Drawing on appraisal theories of discrete emotions, we propose and test a model in which abusive supervision directed toward oneself and toward work unit peers (coworker abusive supervision) are interactively related to generalized feelings of shame, anger, and fear. These discrete emotions, in turn, tend to precipitate distinct responses that do not directly target the supervisor. We tested our hypotheses with a three-wave, time-lagged survey of 285 full-time workers from 55 work units. Consistent with our theorizing, supervisory abuse was associated with stronger feelings of shame while at work when the abusive supervision reported by one's coworkers was lower (vs. higher), whereas abuse had a stronger association with anger when coworkers also perceived relatively high levels of abuse. The distinct action tendencies associated with shame and anger are related to employees engaging in less voice behavior and more interpersonal deviance, respectively, and fear is related to higher turnover intentions. We discuss the study's implications for theory development concerning abusive supervision. 相似文献

The “Learn to Think” (LTT) Intervention Program was developed for raising thinking abilities of primary and secondary school students. It has been implemented in more than 300 schools, and more than 200,000 students took part in the experiment over a 10‐year span. Several longitudinal intervention studies showed that LTT could promote the development of students' thinking ability, learning motivation, and learning strategy as well as raise academic performance in primary schools. This article describes a study of the influence and the delayed effects of LTT on the scientific creativity of secondary school students. One hundred and seven students were selected from a secondary school, 54 of them participated in the LTT every 2 weeks and the rest had not. The intervention lasted 2 years, and the delayed effect was explored half a year after terminating the intervention. The Scientific Creativity Test for Secondary School Students was used four times from pre‐test to delayed post‐test. The results indicated that the LTT did promote the development of scientific creativity of secondary school students, and the effects on the scientific creativity were not necessarily immediate, but tended to be long‐lasting. 相似文献
