相似性词汇同时性加工与相继性加工的比较

为考查同时性学习与相继性学习在相似性材料学习中的特点,本研究以57名大学一年级学生为被试,用英语单词记忆测验考查了相似性英语新单词的同时性学习和相继性学习的差异。结果发现,对于相似性英语新单词来说,同时性学习的效果明显优于相继性学习效果。这表明,两种不同的学习方式在信息处理过程和信息加工水平上存在不同。     

High-capacity spatial contextual memory

Humans show implicit memory for complex spatial layouts, which aids in subsequent processing of these layouts. Research efforts in the past 5 years have focused primarily on a single session of training involving a dozen repeated displays. Yet every day, people encounter many more visual layouts than were presented in such experiments. In this study, we trained subjects to learn 60 repeated displays, randomly intermixed within 1,800 nonrepeated displays, spread over 5 consecutive days. On each day, the subjects conducted visual search on 360 new displays and a new set of 12 repeated displays, each repeated 30 times. Contextual memory was observed daily. One week after the fifth session, the subjects still searched faster on the repeated displays learned previously. We conclude that the visual system has a high capacity for learning and retaining repeated spatial context, an ability that may compensate for our severe limitations in visual attention and working memory.

Simon效应及其反转现象作用机制的研究

研究运用任务干扰的实验范式,试图从探讨刺激出现的空间位置与反应效果之间的关系来推测Simon效应及其反转现象的作用机制。结果表明:(1)当相关刺激-反应匹配不相容时,颜色刺激在左、右位置呈现,当明显标记反应键时,出现Simon效应的反转。(2)当手指遮住反应键的标记时,没有反转。(3)当颜色刺激在中央位置,声音在左、右耳发生时,没有反转。说明显示-控制排列对应性是产生Simon效应反转的最重要因素,逻辑再编码只起到次要的作用。

借鉴管仲农村管理思想加强社会主义新农村建设

管仲作为春秋时期齐国著名的政治家、军事家、经济学家和改革家,对三农(农业、农村、农民)问题高度重视,在农村管理方面有自己的有效策略,是其政治实践的重要组成部分。这些思想在《管子》一书中,得到了充分的体现。今天深入探讨之,对于加强社会主义新农村建设,有着重要的借鉴价值。     

急性心理应激对不同人格类型大学生TNF-α和IL-6的影响

以56名大学生为研究对象,用艾森克人格问卷（EPQ）进行测试,用公共演讲作为应激源,用放射免疫法测定血清肿瘤坏死因子α（TNF-α）和白细胞介素6（IL-6）的含量,旨在探讨急性心理应激对不同人格类型大学生免疫功能的影响。实验结果发现：与对照组相比,急性心理应激后内向组和情绪稳定组TNF-α的明显升高,其余变化均不显著。这说明急性心理应激引起内向、情绪稳定的个体自然免疫增强的现象较明显,而对外向、情绪不稳定个体的作用不明显。     

注意缺陷多动障碍儿童的表征搜索

为探索ADHD儿童在时间维度上的视觉选择性注意的基本机制,揭示其表征搜索能力是否存在缺陷,研究采用RSVP范式,通过实验材料(字母和数字)和呈现方式操作两种搜索方式:序列搜索和平行搜索,比较ADHD儿童(18名)和控制组儿童(17名)的成绩差异。结果发现:①在平行搜索和序列搜索条件下,ADHD儿童的成绩均低于正常控制组;②比较平行搜索和序列搜索条件下的成绩变化,以及由低难度到高难度上成绩的变化,无论是正确率还是反应时均发现ADHD儿童和正常儿童具有相同的成绩变化模式。结论认为ADHD儿童在视觉选择性注意的基本搜索机制上并不存在明显缺陷。     

Contrasting off-line segmentation decisions with on-line word segmentation during reading

In two experiments, we investigated the correspondences between off-line word segmentation and on-line segmentation processing during Chinese reading. In Experiment 1, participants were asked to read sentences which contained critical four-character strings, and then, they were required to segment the same sentences into words in a later off-line word segmentation task. For each item, participants were split into 1-word segmenters (who segmented four-character strings as a single word) and 2-word segmenters (who segmented four-character strings as 2 two-character words). Thus, we split participants into two groups (1-word segmenters and 2-word segmenters) according to their off-line segmentation bias. The data analysis showed no reliable group effect on all the measures. In order to avoid the heterogeneity of participants and stimuli in Experiment 1, two groups of participants (1-word segmenters and 2-word segmenters) and three types of critical four-character string (1-word strings, ambiguous strings, and 2-word strings) were identified in a norming study in Experiment 2. Participants were required to read sentences containing these critical strings. There was no reliable group effect in Experiment 2, as was the case in Experiment 1. However, in Experiment 2, participants spent less time and made fewer fixations on 1-word strings compared to ambiguous and 2-word strings. These results indicate that the off-line word segmentation preferences do not necessarily reflect on-line word segmentation processing during Chinese reading and that Chinese readers exhibit flexibility such that word, or multiple constituent, segmentation commitments are made on-line.
