英语文章阅读过程中的文章标记效应研究

该研究通过三个实验探讨高职生英语阅读的文章标记效应。实验一探讨文章标记对阅读英语长、短文章的影响,结果发现文章标记对英语长文章主题信息保持的促进作用大于对英语短文章主题信息的促进作用。实验二以EyelinkⅡ型眼动仪为工具,考察被试阅读有、无标记文章的主题句的眼动模式的差异,结果发现被试阅读这两类主题句的眼动模式存在显著差异。实验三考察对被试进行文章结构策略训练对文章标记效应的影响,结果发现训练促进了被试对无标记英语长文章主题信息的保持,研究结果支持策略转换假设。     

The development of category learning strategies: What makes the difference?

Category learning can be achieved by identifying common features among category members, distinctive features among non-members, or both. These processes are psychologically and computationally distinct, and may have implications for the acquisition of categories at different hierarchical levels. The present study examines an account of children’s difficulty in acquiring categories at the subordinate level grounded on these distinct comparison processes. Adults and children performed category learning tasks in which they were exposed either to pairs of objects from the same novel category or pairs of objects from different categories. The objects were designed so that for each category learning task, two features determined category membership whereas two other features were task irrelevant. In the learning stage participants compared pairs of objects noted to be either from the same category or from different categories. Object pairs were chosen so that the objective amount of information provided to the participants was identical in the two learning conditions. We found that when presented only with object pairs noted to be from the same category, young children (6 ? YO ? 9.5) learned the novel categories just as well as older children (10 ? YO ? 14) and adults. However, when presented only with object pairs known to be from different categories, unlike older children and adults, young children failed to learn the novel categories. We discuss cognitive and computational factors that may give rise to this comparison bias, as well as its expected outcomes.     

Current status of the motor program: Revisited

The motor program is a concept that has had a major influence on theorizing in the field of motor control. However, there has been a lack of consensus as to what exactly is a motor program and its role in movement organization and execution. In 1994 Morris, Summers, Matyas, and Iansek concluded from a review of the application of the motor program concept in the field of physical therapy that continued use of the term may impede progress in the field. In this paper we examine what has happened to the motor program concept in the thirteen years since the previous evaluation. The review indicates that although the term is still being used in different ways, the theoretical existence of a motor program appears to be generally accepted by researchers in experimental psychology, movement science, and neurophysiology. The recent development of powerful brain imaging techniques may allow determination of whether the motor program should be regarded as a metaphorical or literal concept.     

中文阅读中的边界效应及其消除：事件持续效应

运用动窗技术探讨中文阅读中的边界效应及其消除的条件,包括3个实验。实验一探讨中文阅读中是否存在边界效应,结果发现,边界效应同样存在于中文阅读中;实验二、三探讨时间切分标记能否消除边界效应以及消除的条件,结果发现,只有当切分标记表示的时间在前一事件持续的时间跨度外时才能消除边界效应,如果切分标记表示的时间仍在前一事件持续的时间跨度内,则不能消除边界效应,本研究称此为事件持续效应。从本研究结果中可以得出,时间切分标记降低了主题转换句子所需要的认知加工能量     

年老化与文本理解

年老化与文本理解的研究表明,老年人在表层形式和文本基础两个低水平表征上的理解和记忆能力下降,而在情境模型的建构和提取、更新等加工过程中都没有发现由于年老化引起的能力下降。在介绍这些研究的基础上,从情境模型与另两个低水平加工的不同特点和老年人自身的特殊性两个方面分析了老年人在不同层次表征水平加工能力差异的原因。对情境模型水平加工能力保持的潜在机制及相关的影响因素,以及如何弥补在低水平加工中认知能力因年龄而产生的下降等问题还需要进行探讨     

工作不安全感的研究现状与展望

工作不安全感反映了一种雇员对工作或工作重要特性受到威胁时的感知和担忧。从上世纪80年代以来,它已逐步成为西方组织行为及职业心理健康研究领域中的一个重要构念。文章从5种视角厘清工作不安全感内涵及研究中存在的混淆之处,对其测量工具、研究取向进行介绍,并对有关其前因、后果和调节变量的实证研究成果进行系统性的总结,在此基础上指出未来研究的方向：（1）亟待开发统一的测量工具;（2）在区分组织情境的条件下开展更细化的研究;（3）对前因及后果的细致探索;（4）加强对调节变量的研究;（5）纵向研究的需要;（6）跨文化比较研究。     

文本阅读过程中信息的协调性整合

采用移动窗口阅读技术探讨文本阅读中信息的协调性整合问题。被试为华南师范大学本科生120名。实验材料按照主 人公特征与其目标句行为的关系总体上分为一致与恢复一致两个版本,每个版本都有两个目标句,出现在不同位置。实验1主 要探讨阅读过程中背景信息的激活与协调性整合的性质与特点,实验2主要探讨阅读过程工作记忆中前后信息的协调性整合 问题。采用相关样本t检验分别对两个目标句的阅读时间进行统计分析,结果发现,无论是通过共振激活的背景信息,还是保留 在工作记忆的文本信息,如果与新进入的文本信息有局部的不协调,那么就会产生协调性整合,整合的结果不仅维持了文本的连 贯,而且将相关的信息建构成整体的信息块     

Formal Schooling Influences Two- but Not Three-Dimensional Naming Skills

The modulatory influence of literacy on the cognitive system of the human brain has been indicated in behavioral, neuroanatomic, and functional neuroimaging studies. In this study we explored the functional consequences of formal education and the acquisition of an alphabetic written language on two- and three-dimensional visual naming. The results show that illiterate subjects perform significantly worse on immediate naming of two-dimensional representations of common everyday objects compared to literate subjects, both in terms of accuracy and reaction times. In contrast, there was no significant difference when the subjects named the corresponding real objects. The results suggest that formal education and learning to read and to write modulate the cognitive process involved in processing two- but not three-dimensional representations of common everyday objects. Both the results of the reaction time and the error pattern analyses can be interpreted as indicating that the major influence of literacy affects the visual system or the interaction between the visual and the language systems. We suggest that the visual system in a wide sense and/or the interface between the visual and the language system are differently formatted in literate and illiterate subjects. In other words, we hypothesize that the pattern of interactions in the functional-anatomical networks subserving visual naming, that is, the interactions within and between the visual and language processing networks, differ in literate and illiterate subjects.     

文章结构因素对问题解决迁移影响的研究

探讨阅读过程中文章结构因素对问题解决迁移效果的影响。实验1是在两篇源文章问题解决原理相同条件下探讨其结构类似与否对目标文章的问题解决迁移的影响。结果表明,源文章间结构越不类似,越能促进目标作业问题解决的迁移。实验2是探讨实验1中时间顺序和地理位置两种文章结构在问题解决中是否存在偏性,从而考察实验1的结论是否得以成立。结果证明,时间顺序和地理位置两种文章的组织结构不存在偏性。因而结果可初步表明,文章信息的不同的组织结构方式能促进相同原理条件下的问题解决的迁移。     

速度、步幅与窗口对引导式中文文本阅读工效的影响

引导式显示是在视觉显示终端(VDT)上呈现动态文本的主要方式之一.本研究考察了显示窗口大小、跳动步幅、显示速度等因素对引导式中文文本的阅读工效的影响.实验中采用了3(跳动步幅,被试内变量)×3(显示速度,被试内变量)×2(显示窗口大小,被试间变量)的混合设计,共有18个被试参加了实验.结果发现(1)跳动步幅、显示速度和窗口大小均影响中文文本的阅读工效;(2)达到最佳阅读工效的实验条件在速度和步幅上分别集中于200～400字/分和1～3字/步.最后本文结合中文阅读的相关眼动研究,对这些结果的成因进行了简要的探讨.
