句子理解过程中词类加工的功能性质

句法优先理论假设词类加工功能上优先于语义、动词论元结构和话语信息加工。来自德语和法语的证据显示, 词类违反阻断语义整合和动词论元结构加工, 因而词类优先于语义和动词论元结构。关于词类加工在功能上是否优先于话语信息加工, 尚无来自任何语言的证据。汉语证据尽管显示词类并不优先于语义, 但未充分讨论任务因素的影响。将来研究有必要使用ERP技术和违反范式, 从语义整合、动词论元结构加工和话语水平加工等多个层面, 同时操纵词类的正确性和非句法因素, 考察句法特性上与德语和法语不同的语言, 如汉语和韩语。这方面研究将有助于洞察一个语言的语言学特性如何制约或调整词类加工的功能性质。     

什么决定着用户对产品的完整体验?

用户体验是以用户与产品的交互为基础而形成的用户对产品的完整感受。研究其决定因素可以有针对性地提高用户体验。早期研究表明, 可用性、美感和情感都有重要影响但皆不是唯一的决定因素, 近年来的研究重点关注于多因素整合理论及其模型的建立。在总结实效/享乐结构理论、用户-企业-产品双层结构理论和四种过程模型以提取用户体验影响因素的基础上, 提出目前研究的突破点可在三方面, 一是深入探讨各因素的作用, 二是揭示社会型产品用户体验的形成规律, 三是揭示用户体验随时间变化的规律。     

民族冲突的社会心理机制

民族冲突是影响社会和谐与稳定的重大现实问题, 其社会心理机制是尚未解决的重要科学问题。本项目拟以我国西部地区藏族为例, 纳入社会威胁情境因素, 并整合社会认同理论和社会类别的心理本质论框架下的群际冲突研究。其基本理论命题是：民族冲突形成并不是单一因素所致, 而是基于个体层面、群体层面和社会情境层面的多水平变量相互作用的结果。本项目拟通过既相对独立又彼此关联的三个实证研究, 旨在考察少数民族关于“民族”的心理本质论对民族冲突的预测和影响作用, 探索民族身份延伸和社会威胁情境在其中的影响作用, 从而揭示民族冲突形成的社会心理机制, 旨在为构建民族冲突的预警机制模型奠定基础, 为跨越民族界限、实现多民族和谐共处和完善民族政策提供科学依据。     

中国背景下员工建言行为结构及中庸思维对其的影响

企业的自主创新离不开员工的自发性和创造性, 员工建言行为研究因此愈加受到重视。本研究拟探索中国背景下企业员工建言行为的结构(研究一), 并检验中国人的典型思维特征－中庸思维与中国背景建言行为的关系(研究二)。研究一通过对长三角地区30名企业员工的访谈提取建言行为关键事件, 编制初始问卷, 再通过对159名被试的探索性因素分析, 抽取出顾全大局式和自我冒进式两个建言行为维度; 另一批159名被试的验证性因素分析结果进一步证实了该结构。研究二以278份配对员工为样本, 层次回归分析结果表明, 中庸思维与顾全大局式建言存在正相关, 与自我冒进式建言存在负相关, 且授权对中庸思维与两类建言行为之间关系存在着调节作用。     

语篇语境对句子理解的影响：来自N400的证据

N400作为语义违反的特异性ERP组分,其波幅反映了语义整合加工过程的难度,因此可将其作为研究语篇语境意义建构过程的一项重要指标。语篇语境可分为语言语境和非语言语境。前人一系列基于语篇水平的N400研究表明,从语义的角度上看,语言语境对句子理解具有制约和协调作用,其机制涉及词汇语义启动、场景适宜性、文字内容信息以及因果推理等方面;非语言语境对句子理解具有制约和补充作用,但其机制尚不明确。两种不同来源的语义信息在实时理解中是同时得到加工的     

在多媒体语境条件下词类对儿童英语词汇学习效果的影响

该研究考察了多媒体动画片语境条件下,词类对儿童英语词汇学习效果的影响,结果发现:(1)儿童对名词和形容词的再认成绩显著优于代词;(2)就独立回忆测验而言,名词的成绩显著高于代词,形容词的成绩处于代词和名词之间,但与二者的差异均不显著;(3)就情境回忆测验而言,名词与形容词的成绩差异不显著,二者均显著高于代词;(4)名词与形容词的情境回忆测验成绩均显著高于独立回忆测验成绩,但代词的独立回忆与情境回忆测验成绩差异不显著。总体而言,儿童对名词和形容词的学习效果好于代词,表明词类会对儿童英语词汇学习效果产生影响。     

Momentum in Child Compliance and Opposition

Several event-dependent properties of child-mother interactions were studied to investigate momentum in child oppositional and compliant behavior. It was hypothesized that: (a) compared to an episode of child opposition, an episode of child compliance would be related to an increased likelihood of subsequent child compliance, and (b) the association between a target episode of child opposition and the likelihood of subsequent compliance or opposition would be mediated by the history of the dyadic interaction. These hypotheses were supported. In addition, the presence of interactional sequences predictive of child compliance was inversely related to mother dysphoria and unrelated to mother-reported child externalizing behavior disorder symptoms. Discussion focuses on antecedent interactional patterns as determinants of future child behavior.     

The Influence of Phonological Context on the Sound Errors of a Speaker with Wernicke's Aphasia

A corpus of phonological errors produced in narrative speech by a Wernicke's aphasic speaker (R.W.B.) was tested for context effects using two new methods for establishing chance baselines. A reliable anticipatory effect was found using the second method, which estimated chance from the distance between phoneme repeats in the speech sample containing the errors. Relative to this baseline, error-source distances were shorter than expected for anticipations, but not perseverations. R.W.B.'s anticipation/perseveration ratio measured intermediate between a nonaphasic error corpus and that of a more severe aphasic speaker (both reported in Schwartz et al., 1994), supporting the view that the anticipatory bias correlates to severity. Finally, R.W.B's anticipations favored word-initial segments, although errors and sources did not consistently share word or syllable position.     

The relation between children's reading comprehension level and their comprehension of idioms

We report an investigation of 9-year-olds' ability to interpret idioms in relation to their reading comprehension level. We manipulated whether the idioms were transparent or opaque, whether they were real or novel, whether they were presented in isolation or in a supportive narrative context. As predicted, children were better able to explain the meanings of idioms in context than in isolation. The good and poor comprehenders did not differ in their abilities to interpret transparent idioms in context, but the poor comprehenders were significantly worse at using context to work out the meanings of opaque idioms. The explanation task revealed the source of information used by the children to derive nontarget interpretations. We discuss these findings in relation to idiom processing strategies and Levorato and Cacciari's global elaboration model.
