司法论证型式的修辞研究

司法论证型式是面向司法领域系统研究演绎推论和归纳推论在该领域的作用机理,以及逻辑因素与非逻辑因素的相互作用机理。司法论证型式的修辞研究体现在语用有效性、批判性与策略问题之三大相互联系的层面。司法论证型式的＂语用有效性＂更多地通过＂批判性问题＂得以＂展示＂。在司法环境的具体应用领域,司法论证型式的＂批判性问题＂被转化为各当事人如何运用＂策略＂的问题,是面向司法领域系统研究语言策略（适切的修辞方法）和可接受的司法论证型式群的相互作用机理。如此系统性研究才能刻画论证者与听众的非特设性常识关系,彰显＂语境迟钝＂到＂语境敏感＂法律方法论互动的意义。     

Interpersonal self‐support and attentional bias on negative and positive interpersonal information

Interpersonal self‐support is an indigenous Chinese personality concept. It represents the idealized notion of the kind of personality traits that help individuals deal with interpersonal problems and develop and maintain the harmonic and appropriate social relationships required in China's collectivistic and interdependent culture. It also was assumed to be a protective personality factor with regard to mental health and was found to be negatively related to psychosomatic symptoms. In the current study, cognitive processing of interpersonal information is assumed to be an underlying mechanism that connects interpersonal self‐support with interpersonal relationships and mental health. To test this hypothesis, we conducted two experiments to investigate whether attentional bias on positive and negative interpersonal information was related to high and low interpersonal self‐support. A spatial cueing task and the emotional Stroop task were administered to two samples of high and low interpersonal self‐support Chinese undergraduate students to measure attentional bias. The results from both experiments suggested that high interpersonal self‐support students had an attentional bias toward positive interpersonal information, while low interpersonal self‐support students preferentially attended to negative interpersonal information. Study 1 indicated that attentional bias toward positive interpersonal information was easily engaged in the high interpersonal self‐support group, while attentional bias toward negative interpersonal information was both easy to engage and difficult to disengage in the low interpersonal self‐support students. These results support our hypotheses that high interpersonal self‐support people engage in positive processing of interpersonal information, whereas low interpersonal self‐support people engage in negative processing of interpersonal information. The differential balance between positive and negative processing on interpersonal information may explain why interpersonal self‐support predicts both mental health and interpersonal relationships. In addition, the relational schema may explain why interpersonal self‐support is associated with an attentional bias toward interpersonal information.     

Sample Size Calculation for Estimating or Testing a Nonzero Squared Multiple Correlation Coefficient

The problems of hypothesis testing and interval estimation of the squared multiple correlation coefficient of a multivariate normal distribution are considered. It is shown that available one-sided tests are uniformly most powerful, and the one-sided confidence intervals are uniformly most accurate. An exact method of calculating sample size to carry out one-sided tests (null hypothesis may involve a nonzero value for the multiple correlation coefficient) to attain a specified power is given. Sample size calculation for computing confidence intervals for the squared multiple correlation coefficient with a specified expected width is also provided. Sample sizes for powers and confidence intervals are tabulated for a wide range of parameter configurations and dimensions. The results are illustrated using the empirical data from Timm (1975) Timm, N. H. 1975.

The Influence of Number of Categories and Threshold Values on Fit Indices in Structural Equation Modeling with Ordered Categorical Data

This study examines the unscaled and scaled root mean square error of approximation (RMSEA), comparative fit index (CFI), and Tucker–Lewis index (TLI) of diagonally weighted least squares (DWLS) and unweighted least squares (ULS) estimators in structural equation modeling with ordered categorical data. We show that the number of categories and threshold values for categorization can unappealingly impact the DWLS unscaled and scaled fit indices, as well as the ULS scaled fit indices in the population, given that analysis models are misspecified and that the threshold structure is saturated. Consequently, a severely misspecified model may be considered acceptable, depending on how the underlying continuous variables are categorized. The corresponding CFI and TLI are less dependent on the categorization than RMSEA but are less sensitive to model misspecification in general. In contrast, the number of categories and threshold values do not impact the ULS unscaled fit indices in the population.     

消费者何时愿意选择与规避群体关联的品牌?

消费者何时愿意选择与规避群体关联的品牌?规避群体对消费者的影响机制还需要进一步研究。基于心理逆反理论, 本文通过3个实验探讨自由威胁对消费者选择与规避群体关联的品牌的影响。结果发现, 当消费者感知到高自由威胁时, 选择与规避群体关联的品牌的意愿较高, 心理逆反发挥中介作用, 叙事和自尊水平对上述影响关系具有调节作用。叙事性的信息使得被试因自由威胁所产生的心理逆反降低, 从而对与规避群体关联的品牌的选择意愿降低。对于高自尊的个体, 在高自由威胁时更愿意选择与规避群体关联的品牌; 而对于低自尊的个体, 在高/低自由威胁情况下对规避群体关联的品牌的偏好无显著差异。本文探讨了自由威胁对消费者品牌偏好的影响, 丰富了规避群体和品牌选择的研究; 验证了心理逆反在自由威胁与规避群体关联品牌偏好之间的中介作用, 深化了心理逆反理论。本文对企业在保留现有客户群的基础上, 如何吸引外群体消费者具有一定的指导价值。     

心理距离、封面故事对框架效应的影响

该研究旨在比较志愿决策和“亚洲疾病”决策两种任务领域下,人们风险偏好的特征情况,以考察远、近不同社会距离对风险偏好的影响.同时,在传统的坏封面故事下,增设好封面故事情景,以期发现封面故事作为决策前的必要背景信息对人们决策的影响.选取高中生为被试,结果发现：（1）在近的社会距离下决策时,风险偏好受到时间距离、封面故事、概率和框架的影响;在远的社会距离下,这些因素的影响作用不大;（2）志愿决策中,风险偏好仅在小概率条件下,受封面故事、框架等因素的影响;在好封面故事下,风险偏好受到框架的影响;在坏的封面故事下,风险偏好受时间距离和框架的交互作用影响.     

经颅直流电刺激对健康人群反应抑制的影响

反应抑制是指抑制不恰当的或不符合当前需要的行为的能力, 研究表明反应抑制主要与额下回、背外侧前额叶和前辅助运动区的功能有关。经颅直流电刺激(tDCS)是一种非侵入式脑刺激技术, 近年来对健康人群使用tDCS刺激相应脑区从而影响反应抑制功能的研究日益增多, 但主要研究结果不一致。阐明tDCS影响反应抑制具体的神经机制、减少tDCS研究的异质性、探索更有效的tDCS刺激方式和确定tDCS效果的年龄依赖性差异已成为目前亟待解决的问题。     

教师的语言形式对儿童语言理解的影响

为考察教师的不同语言形式对儿童语言理解的影响,采用独白、半对话和全对话三种语言形式材料,要求不同年级儿童在不同的语言形式条件下完成七巧板图形的识别任务。结果显示,一年级儿童在全对话和半对话语言条件下的正确识别率均显著高于独白语言条件;三年级儿童在全对话语言条件下的正确识别率显著高于独白语言条件;五年级儿童在全对话语言条件下的正确识别率显著高于独白和半对话语言条件。结果说明,在不同年级儿童中,教师的对话语言以不同的内在过程影响儿童的语言理解,这为了解“对话语言易于理解”的发展性机制提供了依据。     

父母心理攻击与小学中高年级儿童问题行为的关系：儿童愤怒和悲伤管理的中介作用

以660名小学中高年级儿童及其父母为被试,采用问卷调查法探讨父母心理攻击与学龄中期儿童内外化问题行为之间潜在情绪机制的差异。结果发现：（1）父亲心理攻击显著正向预测儿童外化问题行为,母亲心理攻击显著正向预测儿童内化问题行为;（2）儿童愤怒失调在父亲和母亲心理攻击和儿童外化问题行为之间起中介作用,儿童悲伤失调在母亲心理攻击与儿童内化问题行为之间起中介作用,儿童愤怒应对在母亲心理攻击和儿童内外化问题行为之间存在中介作用。结果表明,父母心理攻击影响儿童内外化问题行为的情绪机制因儿童自身情绪类型与管理策略的不同而表现出差异性。     

不确定性和预期有效性对运动方向感知决策的影响

环境中的运动刺激往往多变, 更好的方向感知需要同时依赖当前信息和先验信息。然而, 当前刺激的不确定性与先验线索的预期有效性在运动方向感知决策中如何整合尚不清楚。研究采用随机点运动范式, 要求被试判断散点群的整体运动方向, 方向一致的散点为相干点, 其比例越低, 不确定性越高。实验1比较了不同相干点比例下的感知准确度。根据实验1的结果, 选出20%和60%的相干点比例分别对应实验2中散点群的高、低不确定性水平。实验2比较了高、低不确定性和高、低预期有效性(线索正确预测目标的概率)下的感知准确度。结果发现, 随着不确定性的降低和预期有效性的增加, 感知准确度显著提高; 预期效应(高、低有效性下感知准确度的差异)随不确定性的提高而增加。结果表明, 先验信息与感觉信息能在运动方向感知决策中整合。研究为双重控制机制(DMC)理论下主动性与反应性控制协同工作的观点提供了实证支持, 并为交通事故的解释与预防提供了理论依据。
