The effect of discourse structure on depth of semantic integration in reading

A coherent discourse exhibits certain structures in that subunits of discourses are related to one another in various ways and in that subunits that contribute to the same discourse purpose are joined to create a larger unit so as to produce an effect on the reader. To date, this crucial aspect of discourse has been largely neglected in the psycholinguistic literature. In two experiments, we examined whether semantic integration in discourse context was influenced by the difference of discourse structure. Readers read discourses in which the last sentence was locally congruent but either semantically congruent or incongruent when interpreted with the preceding sentence. Furthermore, the last sentence was either in the same discourse unit or not in the same discourse unit as the preceding sentence, depending on whether they shared the same discourse purpose. Results from self-paced reading (Experiment 1) and eye tracking (Experiment 2) showed that discourse-incongruous words were read longer than discourse-congruous words only when the critical sentence and the preceding sentence were in the same discourse unit, but not when they belonged to different discourse units. These results establish discourse structure as a new factor in semantic integration and suggest that discourse effects depend both on the content of what is being said and on the way that the contents are organized.

Extrinsic Cultural Religious Orientation: analysis of an Iranian measure in university students in the United States

Previous research examining Iranian university students suggested that an Extrinsic Cultural Religious Orientation may be more important than an Extrinsic Social Religious motivation in maintaining Muslim religious commitments. The present project demonstrated that a similar conclusion seemed applicable to the largely Christian commitments of American university students. In the United States, an Extrinsic Cultural Religious Orientation Scale displayed a factor structure like that observed in Iran, was a more robust and consistent predictor of psychological adjustment than the Extrinsic Social Religious Orientation, and was sensitive to spiritual as well as religious dimensions of commitment. Peace and Justice and Cultural Foundations factors from this scale were relatively more positive in their adjustment implications than were Disorder Avoidance and Family and Social Order factors. Noteworthy contrasts between the present American and previous Iranian data appeared in Extrinsic Cultural Religious Orientation relationships with a sense of identity and with cognitive empathy. These results confirmed that the Extrinsic Cultural Religious Orientation deserves additional research attention in both Muslim and more secular Western societies.     

Blue or red? The effects of colour on the emotions of Chinese people

Two experiments were performed to examine the effects of red and blue on the emotional pleasure of Chinese people. Experiment 1 explored the effects of the ‘physical’ colours red and blue on emotion, and the results showed that red induced positive and negative emotion, while blue only induced positive emotion. Experiment 2 further explored the effects of the ‘verbal’ colours red and blue on emotion, and the results showed that red induced only positive emotion, while blue induced neither positive nor negative emotion. The findings indicate that the influence of colour on emotion is rooted in both natural and social associations. For Chinese, the associations between blue and positive emotion, and red and negative emotion, were natural associations; however, the associations between red and positive emotion were social associations. Moreover, physical colour and verbal colour stimuli induced emotions by activating different mechanisms: physical colour induced emotions via both natural and social associations, whereas verbal colour induced emotions via social associations.     

A bottom-up view of toddler word learning

A head camera was used to examine the visual correlates of object name learning by toddlers as they played with novel objects and as the parent spontaneously named those objects. The toddlers’ learning of the object names was tested after play, and the visual properties of the head camera images during naming events associated with learned and unlearned object names were analyzed. Naming events associated with learning had a clear visual signature, one in which the visual information itself was clean and visual competition among objects was minimized. Moreover, for learned object names, the visual advantage of the named target over competitors was sustained, both before and after the heard name. The findings are discussed in terms of the visual and cognitive processes that may depend on clean sensory input for learning and also on the sensory–motor, cognitive, and social processes that may create these optimal visual moments for learning.     

基于原型特征因果关系的归纳推理研究

两个实验探讨新特征与类别原型特征之间存在因果关系时,因果关系对归纳推理的影响.实验1探讨不同典型性条件下,新特征与原型特征间的因果关系对归纳推理的影响.实验2探讨不同多样性条件下,新特征与原型特征间的因果关系对归纳推理的影响.研究结果表明,当新特征与原型特征之间存在因果关系时,因果关系会影响归纳推理的力度,但样例典型性和多样性仍是影响人们归纳推理的重要因素.     

小学4～6年级儿童数学应用题表征模型的使用研究

该研究考察了小学4～6年级学生在数学应用题中理解阶段和执行阶段使用表征模型的情况,研究运用实验法对某普通小学的158名4～6年级学生进行了应用题改写任务和缩写任务.结果表明：（1）学生在理解阶段更多地选择情境条件,使用情境模型来表征问题;在执行阶段较少选择情境条件,转而使用问题模型来表征问题;（2）随着年级的升高,相对于优等生来说,其他学生在缩写任务中对情境条件的选择数量越来越少,而优等生在这方面一直都做得很好.差等生识别多余条件的能力并没有随着年级的升高而发生改变,而优等生却在不断增强.     

独立预测作用,还是基础性影响？——价值观对集体行动的影响机制

为阐明价值观在集体行动参与中的地位和影响机制,研究者以利比亚事件为背景,针对现实和网络场域中不同程度的4类集体行动倾向,在天津市957名大学生中进行问卷调查研究,结果发现：价值观显著增加了低成本集体行动倾向解释率,并调节着情绪、工具性动机和社会认同对集体行动倾向的影响;中国人进行集体行动决策时具有集体主义理性计算特征;不同场域和程度的集体行动有其各自规律.结论：价值观在集体行动参与决策中是一种与社会认同类似的基础性变量.     

特殊教育教师工作要求与职业倦怠：心理控制源的中介作用

目的：考察心理控制源在特殊教育教师工作要求与职业倦怠间的中介作用.方法：整群抽取252名特殊教育教师接受量表测量.结果：（1）工作要求与职业倦怠存在显著的性别差异;（2）相关分析表明,工作要求、职业倦怠与心理控制源之间呈显著相关;（3）心理控制源在工作要求与职业倦怠间起着中介作用;独立的中介效应检验中,三种控制源（内控性、有势力的他人、机遇）在工作要求与职业倦怠间都起着部分中介作用;综合模型中,工作要求主要通过有势力的他人这一中介与职业倦怠产生联系,同时也与职业倦怠间存在直接效应.结论：心理控制源是工作要求预测职业倦怠的部分中介因素.
