Towards the end of the second trimester of gestation, a human fetus is able to register environmental sounds. This in utero auditory experience is characterized by comprising strongly low-pass-filtered versions of sounds from the external world. Here, we present computational tests of the hypothesis that this early exposure to severely degraded auditory inputs serves an adaptive purpose—it may induce the neural development of extended temporal integration. Such integration can facilitate the detection of information carried by low-frequency variations in the auditory signal, including emotional or other prosodic content. To test this prediction, we characterized the impact of several training regimens, biomimetic and otherwise, on a computational model system trained and tested on the task of emotion recognition. We find that training with an auditory trajectory recapitulating that of a neurotypical infant in the pre-to-postnatal period results in temporally extended receptive field structures and yields the best subsequent accuracy and generalization performance on the task of emotion recognition. This strongly suggests that the progression from low-pass-filtered to full-frequency inputs is likely to be an adaptive feature of our development, conferring significant benefits to later auditory processing abilities relying on temporally extended analyses. Additionally, this finding can help explain some of the auditory impairments associated with preterm births, suggests guidelines for the design of auditory environments in neonatal care units, and points to enhanced training procedures for computational models.  相似文献

"继善成性"是易学哲学的重要问题.朱熹解释"继善成性"总体上不是为字义的通顺,而在为他的理学本体论作论证.理上气下的基本原则通过易学的语言进一步得到贯彻.善与性、天与人、未发与已发、天理流行与人物成性等,虽也体现了天人之间的密切关联,但又不能将一般天理与已具形质的人性混淆起来."继善成性"说的优长,就在于它将由天至人的生成序列,解释为一个以天道为本而构筑本性的思辨逻辑,同时兼顾个体形质生成带来的特殊性.而本性只是"存"而非"成",以卫护本然之性纯善无恶的假定.  相似文献

Although educational attainment has been identified as a significant factor that reduces uncritical positive attachment to one's country (i.e., blind patriotism), little is known about whether the remedial effect of education on uncritical patriotism is universal across countries with different histories of democratic rule. This article examines the extent to which democracy stock (the accumulated amount of democratic traditions, legacies, and experiences consolidated over time) conditions the relationship between education and blind patriotism. Using international data from 33 countries, the article shows that the remedial effect of education is more pronounced in countries with larger stocks of democracy than in countries with higher levels of democracy (current or recent). The results imply that the political socialization of critical patriotism is a cumulative process in which citizens internalize their potentially democratic competencies (e.g., knowledge, skills, and dispositions) and develop a sense of national attachment based on critical reflection on government policy and practice (i.e., critical loyalty) over an extended period of time.  相似文献

国际合作中知情同意面临的难题及思考   总被引:1,自引:0,他引:1  
目前在医学研究的国际合作中,知情同意原则在实施中出现了许多争议和难题.结合一些典型案例,对知情同意的跨文化研究、知情同意表格的误解以及保护受试者与自由研究之间的权衡等问题进行了深入地分析.指出:加强交流、相互尊重、求同存异是解决跨文化研究的必由之路;严格审查、加强监管是避免知情同意流于形式的重要手段;鼓励与防范并举才能达到双赢的局面.  相似文献

为适应全球卫生事业的迅猛发展,面对医学教育落后于医学发展的现状,转化医学教育迫在眉睫。在第三代“以系统为基础”的教育改革中,培养医学生的哲学思维无疑是其重要环节之一。思维方式必须在医学生步入临床时就要开始正确培养,一旦开始阶段就养成不正确的思维方式、不但会导致医疗过程中的失误,而且再想改变将会有很大难度。本文通过对医学哲学重要性的探讨,剖析医学生哲学思维的不足,阐述了医学生,临床实习过程中应掌握的几种哲学思维方式。旨在提高医学生的哲学理念,促进以岗位胜任能力为导向的医学教育转型发展。  相似文献

In her short story “Stable Strategies for Middle Management,” Eileen Gunn imagines a future in which Margaret, an office worker, seeks radical genetic enhancements intended to help her secure the middle-management job she wants. One source of the story’s tension and dark humor is dramatic irony: readers can see that the enhancements Margaret buys stand little chance of making her life go better for her; enhancing is, for Margaret, probably a prudential mistake. This paper argues that our positions in the real world are sufficiently similar to Margaret’s position in Gunn’s fictional world that we should take this story seriously as grounding an argument from analogy for the conclusion that radical genetic enhancements are, for us, probably a prudential mistake. The paper then defends this method. When the question at hand is one of speculative ethics, there is no method better fit to the purpose than argument from analogy to speculative fiction.  相似文献

In this study, we explored the structure of pupils’ creativity in primary education following the Amusement Park Theory, by investigating undiscovered linkages between the domains of writing, mathematics, and drawing. More specifically, we examined: (a) whether some domains and general thematic areas are more closely related to each other than to others, (b) whether literacy and mathematical ability are specific underlying traits of creativity in writing and mathematics, respectively, and (c) whether intelligence and divergent thinking are related to creativity in all domains. The sample consisted of 331 Dutch 4th grade pupils. For each research question, a model was analyzed using structural equation modeling. We found creativity in mathematics and creativity in writing to be most similar, followed by creativity in mathematics and creativity in drawing, with creativity in writing and creativity in drawing being least similar. Additionally, we found evidence for several underlying traits (i.e., literacy ability and mathematical ability) and initial requirements of creativity (i.e., intelligence and divergent thinking), none of which were important for creativity in only one domain, and of which only intelligence was important for creativity in all domains. Herewith, our study provides insights regarding the complexity of the structure of creativity in primary education.  相似文献

This study investigates the joint effects of individual characteristics and the labour market on career mobility. We propose that level of education, openness to experience, and a favourable labour market relate positively to employees crossing organizational, industrial, and occupational boundaries. Management programme alumni (N = 503) provided information through an online survey about their career histories, their level of education, and their openness to experience. Additionally, we used the unemployment rate as an indicator for yearly changes in the labour market. The results of our cross-classified multilevel analysis indicate that both individual characteristics and the labour market are determinants of career mobility. Level of education had a positive effect on organizational and industrial boundary crossing, and changes in the labour market related to organizational boundary crossing. Against our assumptions, openness to experience had no effect on career mobility, and none of the predictors were related to occupational boundary crossing. Our results demonstrate the importance of investigating career mobility from a boundary perspective combined with a focus on both individual and contextual characteristics. The dominance of education compared to personality and the difficulty of explaining occupational mobility open new research avenues and yield practical implications for employees, career counsellors, and organizations.  相似文献
