隐喻在文章语境中的理解--概念隐喻理论探讨

概念隐喻理论认为,语言系统中存在着广泛的隐喻一致性,人们对于隐喻的理解是通过将其匹配到基本的概念隐喻来进行的。但有研究者指出,除了一些新颖的隐喻,惯用隐喻的理解并不需要概念匹配。本研究认为,概念隐喻已经储存在长时记忆中,在文章语境中,无论惯用隐喻还是新颖隐喻的理解都可能产生概念匹配。三个实验支持了这一假设。实验一通过目标句的阅读反应时探讨不同文章版本下目标句的理解情况;实验二和实验三从事后与即时两方面对各种文章版本下的概念匹配情况进行比较。研究结果支持了概念隐喻理论。     

Utilizing Participatory Mapping and GIS to Examine the Activity Spaces of Homeless Youth

Although previous studies have informed our understanding of certain aspects of youth homelessness, few studies have critically examined the spatial and social environments utilized by youth as they navigate life on the streets. This study employed participatory mapping and Geographic Information Systems (GIS) to examine the activity spaces of homeless youth as they relate to sense of community and psychological well‐being. Participants were 28 youth experiencing homelessness in Portland, Oregon, USA. Results suggest that youth engage most frequently in service‐related activities, and their activity participation is significantly associated with sense of community and psychological well‐being. The utility of innovative participatory methods for better understanding the diverse experiences of homeless youth is discussed alongside examination of their practical implications.     

Who Is This God of Whom You Speak? Counseling Students' Concept of God

Many clients bring a belief in God or a Higher Power into counseling sessions. What is less clear, however, is how counselors conceptualize “god,” which may affect how spirituality is integrated in the counseling process. To explore this question, the authors conducted a concept map study of god images among counseling students. Results suggest that students harbor broad and diverse conceptualizations of god, which may affect the counseling process.     

中国空间隐喻研究现状与发展趋势——基于CiteSpace的知识图谱分析

通过CiteSpace对空间隐喻研究文献进行可视化分析发现,中国对于空间隐喻的研究始于1999年,经历了起步探索期、爆发期,现进入平稳深化期; 学科分布以语言学为主,文学与心理学为辅; 多数研究者更倾向单次独立研究而缺少持续与合作研究,仅构成一个作者群,另外也有一些小合作团队,只局限于两人合作,合作力量较弱; 各机构之间合作缺乏; 研究热点集中于空间隐喻、隐喻、认知、意象图式、空间、映射汉语、隐喻拓展等,近年来转向了概念隐喻、道德、道德概念、垂直空间隐喻和具身认知,且具身认知持续至今; 空间隐喻研究主要围绕空间隐喻、认知语言学、意向图式、方位词、映射、隐喻、认知和具身认知这八个主题开展。由此可知,未来的研究中可扩展学科范围、加强各作者和各单位之间的合作、探索其他研究热点。     

Inception and ResNet features are (almost) equivalent

Deep convolutional neural networks (CNNs) are the dominant technology in computer vision today. Much of the recent computer vision literature can be thought of as a competition to find the best architecture for vision within the deep convolutional framework. Despite all the effort invested in developing sophisticated convolutional architectures, however, it’s not clear how different from each other the best CNNs really are. This paper measures the similarity between two well-known CNNs, Inception and ResNet, in terms of the properties they extract from images. We find that the properties extracted by Inception are very similar to the properties extracted by ResNet, in the sense that either feature set can be well approximated by an affine transformation of the other. In particular, we find evidence that the information extracted from images by ResNet is also extracted by Inception, and in some cases may be more robustly extracted by Inception. In the other direction, most but not all of the information extracted by Inception is also extracted by ResNet.The similarity between Inception and ResNet features is surprising. Convolutional neural networks learn complex non-linear features of images, and the architectural differences between systems suggest that these non-linear functions should take different forms. Nonetheless, Inception and ResNet were trained on the same data set and seem to have learned to extract similar properties from images. In essence, their training algorithms hill-climb in totally different spaces, but find similar solutions. This suggests that for CNNs, the selection of the training set may be more important than the selection of the convolutional architecture. keyword: ResNet, Inception, CNN, Feature Evaluation, Feature Mapping.     

映射具体性和语境线索对新颖隐喻加工的影响

研究旨在考察映射具体性对新颖隐喻加工的影响及语境线索的作用,并进一步探索映射具体性高的隐喻加工困难的原因。实验1的ERPs结果发现：知觉隐喻反应时显著长于物理-心理隐喻和直接语义;两类隐喻在有语境线索下的反应时显著长于无语境线索。有语境线索的知觉隐喻比无语境线索在前部位置诱发了更负的N400成分,在中部诱发了更正的LPC成分;有语境线索的物理-心理隐喻在前部、顶部比无语境线索诱发了更正LPC成分。实验2的语义判断任务结果发现：在映射具体性不同的两类隐喻中,多映射通路隐喻的反应时均显著长于单一映射通路隐喻。总体结果支持语境线索对新颖隐喻加工的干扰效应。     

数量适应后效的皮层映射特征

本研究探讨了观察者与观察目标存在相对运动时视觉系统对目标数量特征的适应后效的皮层映射特征, 并与对比度适应后效的映射规律进行比较。包括两项实验。其中, 实验一要求被试在适应目标后转换注视点, 考察眼跳后相同和不同视网膜区域以及相同和不同空间区域的适应后效, 发现数量适应后效具有部分空间-皮层映射特性, 而对比度适应后效则表现出完全的视网膜-皮层映射特征。实验二采用固定的注视点, 考察目标运动后目标原位置和新位置区域的适应后效, 发现数量适应后效不完全依赖于视网膜-皮层映射, 它可以“追随”客体运动重新映射到新的位置, 表现出基于客体映射的特征, 而对比度适应后效则完全依赖于视网膜-皮层映射, 不能“追随”客体移动在目标新位置重新形成映射。两项实验结果提示, 相对于对比度等低级表面特征而言, 数量特征对目标的描述涉及更高的加工水平, 它可以与观察目标的相对运动信息进行整合, 且这种整合在眼跳和非眼跳的观察条件下都可发生。     

词汇学习中“快速映射”现象的机制

词汇学习对于语言获得及有关认知能力发展有重要意义.通过考察儿童词汇的快速增长,研究者提出词汇学习涉及一个"快速映射"(fast mapping)过程.最近20多年,大量研究者考察了快速映射机制.一类研究者认为儿童依靠一些认知偏向来猜测新单词的意义;另一类研究者认为词汇频率、言语最末位置等语言环境因素影响该过程.最新研究趋向(如生成联合模型和词汇学习的贝叶斯推理模式)认为这两类因素都很重要,但对它们的作用时间和比重等仍有争议.
