初中生社会支持的类型及对学习的影响

利用潜在剖面分析法和辨别分析法对374名初中生社会支持的类型进行考察,探讨不同社会支持类型初中生的特点,分析社会支持类型对学习动机、学习策略、成绩的影响。结果表明：（1）初中生社会支持分为亲密无间型、若即若离型和家庭疏远型3种。（2）亲密无间型初中生的社会支持最高,家庭疏远型初中生的社会支持尤其是家庭支持最低,而若即若离型初中生的社会支持处于亲密无间型和家庭疏远型之间。（3）社会支持类型对学习动机、学习策略、成绩有显著影响。     

负面情绪和说服策略对品牌关系再续意愿的影响

营销学和心理学的已有研究表明, 负面情绪会影响信息处理过程。因此, 企业在品牌关系再续的实践中, 必须结合消费者负面情绪来选择适当的说服策略。基于此, 通过区分反驳型说服策略和诊断型说服策略, 并将其联结于消费者的情绪特点(情绪类型与情绪强度), 经由两个实验探讨了不同情绪特点的消费者对两种说服策略的反应。实验一初步证明了负面情绪类型(后悔和生气)调节说服策略对原谅的影响。实验二证明了负面情绪强度(低和高)调节说服策略对原谅的影响, 并进一步检验了实验一的结论。即当负面情绪强度低时, 负面情绪类型的调节作用不显著; 但是, 当负面情绪强度高时, 负面情绪类型的调节作用显著。此外, 两个实验均验证, 根据消费者负面情绪特点, 适当的说服策略有利于消费者原谅品牌, 进而产生品牌关系再续意愿。     

3～5岁儿童基于能力特质进行信任判断的策略及其发展

研究采用对偶选择的范式考察了3～5岁儿童基于能力特质进行信任判断的策略。让144名3～5岁儿童在面对能力强和不挑食这两类人时做出信任判断。结果发现3～4岁儿童的信任判断受老师评价偏向的影响,他们的信任选择与老师评价偏向一致。5岁儿童的信任判断则不受老师评价偏向的影响。这些结果表明3～4岁儿童信任判断的策略是依据特质效价,5岁儿童的策略是依据特质意义。     

特质应对与展现规则对情绪劳动的影响

采用2×3组间设计, 检测特质应对(积极与消极)与展现规则(积极、消极、无规则)对情绪劳动的影响。结果表明, 积极应对引起更多深层动作; 积极规则下出现较少表层扮演(与消极应对比)。积极和消极规则都引起较多深层和表层动作。积极应对在积极规则下表层扮演较少(与消极规则比); 消极应对在积极规则下表层扮演较多(与消极规则比)。研究提示, 特质情绪性可能是调节展现规则与情绪劳动关系的重要原因。

Matching and oddity relational learning by pigeons (<Emphasis Type="Italic">Columba livia</Emphasis>): transfer from color to shape

Relational learning, as opposed to perceptual learning, is based on the abstract properties of the stimuli. Although at present there is no doubt that pigeons are capable of relational behavior, this study aims to further disclose the conditions under which it occurs. Pigeons were trained in an outdoor cage on a matching-to-sample or an oddity-from-sample task, with colored cardboard stimuli presented horizontally. The apparatus involved three sliding lids on which the stimuli were drawn and which, when displaced, revealed the reinforcement. The lids were either adjacent to each other or somewhat separated. Training sessions involved two colors, and test sessions six different colors (same dimension test), or six different shapes (different dimension test). One group of birds trained under the ‘adjacent’ condition failed when tested with new stimuli, but succeeded in both dimension tests after training under the ‘separate’ condition. Two other groups of birds succeeded in all tests after training under the latter condition. These results show that depending on procedural details, pigeons are or are not able to transfer from one visual dimension to another, thus extending previous related findings.     

不同条件下拟合指数的表现及临界值的选择

在本模拟研究中设计了6种样本容量,6种因子载荷,和4种评分等级,并考察了正态和非正态分布两种情况。采用的错误模型为参数误置（真模型中每个因子各由5个题目来测量,错误模型中则是第一个因子由6个题测量,另两个因子各由4个和5个题来测量,即有一个因子载荷被误置）模型。结果发现（1）样本量、载荷量、评分等级数和分布形态都对GOF的取值确有影响。其中分布形态的影响最大。NNFI、IFI在不同条件下的平均值是最稳定的,其次是CFI、RMSEA和SRMR。它们都算是值得推荐的GOF,尤其是NNFI和IFI。（2）在正态分布中,当样本量≥1000时,根据NNFI、IFI、CFI、RMSEA、SRMR对模型是否拟合做出判断时有很低的两类错误率,在样本量<1000时则不理想。在偏态条件下无论选择哪个GOF两类错误率都很高。（3）采用2指数策略在很多情况下也不能显著降低两类错误率。（4）由于在数据分布非正态,或正态但样本量<1000时是难判断模型是否拟合的。因此我们提出了2界值策略。即为每个GOF确定上下两个界值。低于下界值时可判断模型是不正确的,而高于上界值时则可判断模型是正确的。GOF取值处于上下界值之间时难以判断模型是否拟合,只能说越高拟合的可能性越大。这时就要通过跨样本验证和增加样本量来确定模型是否正确     

An intervention study of the effects of the coping strategy of "finding positive meaning" on positive affect and health

Previous research has shown that positive affect (PA) is associated with the coping strategies of "searching for and finding positive meaning." The purpose of this study was to investigate the relationship between the coping strategy of "finding positive meaning" and PA using an intervention method. Additionally, inasmuch as previous research has revealed that PA is associated with physical and mental health status, the current study measured health status in order to carry out a preliminary test as to whether PA increased by the intervention can also improve health. Participants in the intervention group (Japanese graduate students; 13 men and 16 women) reported the most stressful event during the past 3 days and its positive meaning, while those in the control group (13 men and 15 women) reported the most stressful event alone. Both groups reported twice a week for 5 successive weeks using e-mails. Three questionnaires, the Japanese version of the Positive and Negative Affect Schedule scales for measuring positive and negative affects (NA), the situational version of the General Coping Questionnaire for coping strategies, and the Japanese version of the General Health Questionnaire for health status, were administered to all participants just before the start of the intervention, after the conclusion of the intervention, and at the 5-week follow-up session. Results revealed that the "finding positive meaning" coping strategy and PA were enhanced by the intervention in the follow-up for men and women with no changes in NA. For the health scales of the General Health Questionnaire, no significant group-related effects were observed. Thus, the intervention had no significant influence on NA or health status. Implications of these findings for future research are discussed along with a few limitations in this study.
