社会知觉视角下道德诉求方式如何提升劝捐效果

如何有效地引导个体“慷慨解囊”一直是理论和实践都关注的热点。基于道德基础理论和刻板印象内容模型, 研究考察了在不同社会知觉(温暖型vs.能力型)的劝捐主体中, 两种道德诉求方式(个体人道诉求vs.群体规范诉求)对劝捐效果的影响及其内在机制。3个实验的结果显示：温暖型(能力型)劝捐主体与个体人道诉求(群体规范诉求)更为契合, 更有利于提升劝捐效果; 温暖型劝捐主体进行个体人道诉求主要通过唤起个体的自我效能而提升劝捐效果, 而能力型劝捐主体进行群体规范诉求则主要通过增强个体的反应效能而提升劝捐效果。     

Inpatient suicide in a Chinese psychiatric hospital

Little is known about the risk factors for suicide among psychiatric inpatients in China. In this study we identified the risk factors of suicide among psychiatric inpatients at Guangzhou Psychiatric Hospital. All psychiatric inpatients who died by suicide during the 1956-2005 period were included in this study. Using a case-control design, 64 inpatients with schizophrenia who died by suicide were compared with a matched 64 controls. The results indicate that the rate of suicide was 133.1/100,000 admissions (95%CI 103.4-162.9). There were no significant differences in the method, location, or time of suicide between male and female inpatients. The number of hospitalizations was significantly larger in the suicide group than that in the control group. In logistic regression analyses, guilty thought, depressive mood, and suicidal ideation and suicide attempt 1 month before hospital admission were identified as independent predictors of suicide among inpatients with schizophrenia. The findings of risk factors for schizophrenic inpatient suicide should be taken into account when developing interventions to prevent suicide among these patients.     

A hierarchical process-dissociation model

In fitting the process-dissociation model (L. L. Jacoby, 1991) to observed data, researchers aggregate outcomes across participant, items, or both. T. Curran and D. L. Hintzman (1995) demonstrated how biases from aggregation may lead to artifactual support for the model. The authors develop a hierarchical process-dissociation model that does not require aggregation for analysis. Most importantly, the Curran and Hintzman critique does not hold for this model. Model analysis provides for support of process dissociation--selective influence holds, and there is a dissociation in correlation patterns among participants and items. Items that are better recollected also elicit higher automatic activation. There is no correlation, however, across participants; that is, participants with higher recollection have no increased tendency toward automatic activation. The critique of aggregation is not limited to process dissociation. Aggregation distorts analysis in many nonlinear models, including signal detection, multinomial processing tree models, and strength models. Hierarchical modeling serves as a general solution for accurately fitting these psychological-processing models to data.     

脑损伤新生儿救治的选择

脑损伤是婴儿死亡、儿童残疾的主要原因之一。关于有严重脑损伤新生儿（包括脑瘫、智能精神发育落后等）是否该救治,牵涉到很多矛盾的思想观点。通过分析新生儿期脑损伤发生的高危因素,且提出相应的综合处置意见,认为要和谐地解决此矛盾,需要医院、家庭和社会有关部门的共同努力。     

Fisher与Neyman–Pearson的分歧与心理统计中的假设检验争议

假设检验思想的提出者Fisher与Neyman–Pearson在统计模型的方法论基础、两类错误的性质、显著性水平的理解、以及假设检验的功能等方面存在诸多分歧, 使得心理统计中最常用的原假设显著性检验模式呈现出隐含的各种矛盾, 从而引发了应用上的争议。心理统计不仅需要检讨现有检验模型的模糊之处和提出其他补充性的统计推论方式,更应注重反思心理统计的教育传统, 以建立更加开放和多元的统计应用视野, 使心理统计为更好地心理学研究服务。     

广东省城乡初中生元认知水平比较研究

研究采用自编问卷和访谈法对城乡初中生进行元认知水平的对比研究,结果表明：1）城乡初中生元认知水平总体差异显著,农村初中生的元认知水平总体低于城市初中生的元认知水平。2）城乡初中生在认知前元认知体验和认知中元认知知识维度上差异显著。认知前元认知知识、认知中元认知体验、认知后元认知知识、认知后元认知体验之间无显著性差异。建议加强教师和学生元认知训练,提高学生元认知水平。     

Sensation-seeking, Internet dependency, and online interpersonal deception.

This study aimed to elaborate the relationships between sensation-seeking, Internet dependency, and online interpersonal deception. Of the 707 individuals recruited to this study, 675 successfully completed the survey. The results showed high sensation-seekers and high Internet dependents were more likely to engage in online interpersonal deception than were their counterparts.     

工作记忆模型的第四个组成部分——情景缓冲器

工作记忆的提出迄今已有30多年的历史了,随着实验方法和技术的发展对工作记忆的研究取得了很大的突破,但在很多问题上仍存在争议,特别是在工作记忆与长时记忆、语音回路与视空间模板的联结上的解释还有许多不足.基于此,Baddeley于2000年提出了工作记忆模型的第四个组成部分--情景缓冲器(episodic buffer).情景缓冲器是一个容量有限的暂时贮存多种编码信息的装置,它受中央执行系统的控制,而中央执行系统能够通过意识觉察从存贮中提取信息,反映信息,在必要的时候能够修正信息.新的工作记忆模型更加完整,更加有解释力.     

机械特征相似程度不同情况下类别联想对类别学习的影响

探讨机械特征相似程度不同情况下类别联想对类别学习的影响,共包括2个实验.被试是广州某大学70名学生.探讨类别内部机械特征相似程度不同情况下,由主题特征激活的类别联想对类别学习的影响.结果表明:(1)在类别内部项目机械特征相似程度高的情况下,一致主题特征激活的类别联想对类别学习起促进作用;不一致主题特征激活的类别联想没有对类别学习起阻碍作用.(2)在类别内部项目机械特征相似程度低的情况下,不一致主题特征激活的类别联想对类别学习起阻碍作用.     

Talking about others facilitates theory of mind in Chinese preschoolers

A longitudinal study and a training study were conducted to show that simply referring to others facilitated theory of mind (ToM) development in Chinese children. In Study 1, 3- to 4-year-old Chinese children (N = 52) were tested on ToM and autobiographical memory (AM). One year later, in the group of children who initially failed the false belief tasks, only those who increased their references to others in AM recall passed the tasks. In Study 2, Chinese preschoolers who were trained to talk about others through storytelling showed improvement in their ToM performance. These findings suggest alternative pathways for ToM development in non-Euro-American context.
