北京地区中学生学习策略水平的调查研究

本研究采用中学生学习策略量表测查了542名中学生的学习策略使用情况。结果表明：(1)中学生学习策略量表有着较高的信度和效度,分量表项目间有良好的一致性。(2)从初三到高三,学生的学习策略水平没有表现出随年级增长而提高的趋势,甚至在时问管理、焦虑、信息加工等分量表方面有下降的表现。(3)女生在态度,动机,学习辅助和自我测试分量表上的得分明显高于男生;男生在信息加工分量表上的得分明显高于女生。(4)优差生在学习辅助和自我测试两个分量表上的得分没有明显差异,在其余分量表上均有显著差异。     

越描越黑

就在前不久的2005年2月26日,中央电视台新闻联播播放了一条新闻,表扬华中科技大学“建设网络教育新型平台,拓展思想政治教育领域”。报道中,华中科大党委副书记刘献君说:“过去我们的人文讲座,是在教室里面。现在大学生自己把它搬到网上直播……扩大了覆盖面,提高了教育效果。”点评:所谓“过去我们的人文讲座”,不知是否包括那个     

Visual working memory enhances target discrimination accuracy with single-item displays

The maintenance of information in visual working memory has been shown to bias the concurrent processing in favor of matching visual input. The present study aimed to examine whether this bias can act at an early stage of processing to enhance target feature perception in single-item displays. Participants were sequentially presented with two distinct colored stimuli as memory samples and a retro-cue indicating which of the two samples should be maintained for subsequent memory test. During the retention interval, they had to discriminate the gap orientation of a Landolt target presented through a single visual stimulus that could match one or neither of the two samples. Across two experiments, we consistently found that discrimination performance was more accurate when the Landolt target was situated within a stimulus that matched the sample being retained in visual working memory, as compared with when the target was not. This effect cannot be attributed to the mechanism of passive priming, because we failed to observe priming effects when the stimulus containing the target matched the sample that was retro-cued to be irrelevant to the working memory task, as compared to when the stimulus matched neither sample. Given the fact that target stimuli were presented in single-item displays wherein external noise was precluded, the present findings demonstrate that the working memory bias of visual attention operating in the absence of stimulus competition facilitates early perceptual processing at the attended location via signal enhancement.

     

学优儿童学习适应性、学习习惯和应试技能及其关系

采用《儿童学习适应性调查表（I）、（II）》和《学习习惯与应试技能自我测查表》对231名学优儿童的学习适应性及其相关因素进行调查。结果表明：（1）学优儿童和学习不良儿童的学习适应性、学习习惯和应试技能存在显著性差异;（2）城市学优儿童的学习生活、学习习惯、学习方法、阅读习惯和技能明显优于农村学优儿童;（3）学优女生在学习适应性明显好于男生,但女生有独立性差、情绪障碍等症状,而学优男生则在学习习惯方面不如女生。在学习习惯与应试技能方面则不存在显著的性别差异;（4）除了对学校的态度因子外,学优儿童学习适应性与其学习习惯和学习方法、阅读习惯和技能、准备与应试等有显著性相关。     

刺激呈现时间对汉字语义加工脑偏侧化的影响

以往关于汉字字词识别脑功能偏侧化的研究发现了左半球优势、右半球优势或者大脑两半球均势三种不同的结果。该研究采用一侧化Stroop范式(刺激分别只呈现于左视野、中央视野或右视野中),通过系统地改变刺激呈现时间以期探讨刺激呈现时间是可以解释这些不一致结果的可能因素之一。结果显示:对于右利手被试,在刺激呈现时间为60 ms时右半球出现了较强的Stroop效应,在刺激呈现200 ms时左右半球的Stroop效应没有表现出差异,在刺激呈现时间较长时左半球表现出较强的Stroop效应。该结果提示,随着刺激呈现时间的延长,语义优势发生了从右半球到左半球的转换。     

小学生外显的说明性文本段落主旨推断学习研究

Development and validation of a Christian-based Grief Recovery Scale

The purpose of this study was to develop and validate a Christian-based Grief Recovery Scale (CGRS) which was used to measure Christians recovering from grief after a significant loss. Taiwanese Christian participants were recruited from churches and a comprehensive university in northern Taiwan. They were affected by both the Christian faith and Chinese cultural beliefs. The CGRS is developed through replicated factor analyses in three stages. The final version of the CGRS retains 35 Likert-type items and consists of six factors: spiritual well-being; recovering meaning and sense of control; ongoing physical and emotional responses; reassuring faith; strongly missing a deceased loved one; and life disturbance. The evidence for CGRS reliability and validity is highlighted. Implications for research and counselling practice are suggested.     

Using a Two-Tier Test to Examine Taiwanese Graduate Students’ Misunderstanding of Responsible Conduct of Research

The present study investigates Taiwanese graduate students’ general understanding and misunderstanding of Responsible Conduct of Research (RCR). A total of 580 graduate students responded to the self-developed Responsible Conduct of Research Reasoning Test. The results reveal that, first, students did not have sufficient knowledge to reason why a particular instance of research (mis)conduct was doable or not. Second, the statistical results show that female students, students majoring in the humanities or the social sciences, doctoral-level students, and students with RCR-related training outperformed others. In addition, the misbehaviors that students judged relatively uncritically comprise the following nine categories: (a) seeing authorship as a property or power, (b) misinterpreting research coauthors’ responsibilities, (c) inaccurately conducting the informed-consent process, (d) fabricating and falsifying research data, (e) misinterpreting the correct citation of research sources, (f) holding vague concepts of self-plagiarism, (g) misinterpreting the Taiwan Copyright Act, (h) accepting duplicate-publication practices, and (i) accepting piecemeal publication practices. The present study discusses participative students’ major misunderstandings of actual RCR-related practices. The study also presents further implications and suggestions based on the findings.     

Formation of profuse <c+a> dislocations in deformed calcium-containing magnesium alloys

We report that <c+a> pyramidal slipping could be more easily activated in textured Mg–Ca alloys with increasing Ca contents dissolved in α-Mg matrix under tensile deformation, and it is proposed that the decreased stacking fault energy plays the critical rule. In contrast, only twins and <a> basal dislocations are observed in the compressed samples. The results would provide insight into understanding of the deformation mechanism and designing more ductile Mg alloys.     

Divergent thinking and constructing episodic simulations

Divergent thinking likely plays an important role in simulating autobiographical events. We investigated whether divergent thinking is differentially associated with the ability to construct detailed imagined future and imagined past events as opposed to recalling past events. We also examined whether age differences in divergent thinking might underlie the reduced episodic detail generated by older adults. The richness of episodic detail comprising autobiographical events in young and older adults was assessed using the Autobiographical Interview. Divergent thinking abilities were measured using the Alternative Uses Task. Divergent thinking was significantly associated with the amount of episodic detail for imagined future events. Moreover, while age was significantly associated with imagined episodic detail, this effect was strongly related to age-related changes in episodic retrieval rather than divergent thinking.
