语境影响反语理解的眼动研究元分析

运用元分析的方法考察语境在反语理解中的作用及其相关的调节因素。通过文献检索,共搜集了13篇有效文献,16项实验数据,包含了806名被试。结果发现：(1)在反语理解正确率指标上反语明显比字面语更难理解,语境与目标反语不一致会产生额外推理过程,导致反语理解相对困难。(2)目标区反语和字面语在第一遍阅读时间指标上没有差异,但是在回视路径阅读时间和总阅读时间指标上反语的加工时间显著更长,这表明语境在反语加工的后期产生了作用,读者需要在加工后期对反语进行重新分析和整合,这一结果基本符合模块化理论的预测。(3)熟悉性对目标区的第一遍阅读时间和总阅读时间产生了调节作用,表明不管语境强度如何,熟悉的意义首先被加工,这一结果与分级显著性假设的预测基本一致。     

The significance of blushing for fair- and dark-skinned people

Since blushing is difficult to detect in people with dark skin, their experience of blushing may differ fundamentally from people with fair skin. To investigate this issue, cheek temperature and forehead blood flow were measured in 16 Caucasians and 16 Indians during mental arithmetic and singing. Caucasians (particularly females) thought that they blushed more intensely than Indians, and also reported greater self-consciousness when singing. Vascular responses did not differ between groups. However, skin tone moderated the association between vascular responses and ratings of self-consciousness, blushing intensity, blushing propensity and fear of negative evaluation. These findings support the notion that the visibility of blushing influences the nature of emotions experienced in embarrassing social encounters.     

Attachment experience and cortisol recovery from romantic conflict among young Chinese couples: A dyadic analysis

Using a sample of young adults, the present study investigated how the participants' attachment to romantic partners was related to that with their parents and peers and how this specific attachment experience was associated with their physiological stress response. We examined 121 pairs of young Chinese (N = 242) heterosexual couples (men's age: 22.26 ± 2.40; women's age: 21.62 ± 2.22) and their attachment to parents, peers, and romantic partners as well as their cortisol recovery from romantic conflict. Robust actor–partner interdependence mediation models showed that women's insecure parental and peer attachment was associated with blunted cortisol recovery from romantic stress through their fearful attachment with romantic partners, whereas men's insecure parental and peer attachment was associated with their partners' adaptive cortisol recovery from romantic stress through their fearful romantic attachment. These findings suggested that women's hypothalamic–pituitary–adrenal-axis functioning seemed to be more strongly associated with their own and their partners' attachment relationships compared to men.     

左前额叶参与非相关词对的语义编码过程──来自光学成像的佐证

通过研究左前额叶在非相关同对的语义编码过程中的作用,探讨近红外光学成像技术用于脑高级认知活动检测的可行性。被试在两种实验条件下分别学习视觉呈现的20个汉字非相关词对,要求被试或将词对组成一个有意义的句子(深加工),或判断两个词是否具有相同的结构组合(浅加工)。光学成像器即时记录连续光透过额骨及前额皮层后760nm和850nm的漫射光强变化,以此推测相应脑组织的血容量变化。结果表明,与浅加工相比,左下前额叶在深加工时的血容量增多,尤其是背外侧部分。     

β_2-糖蛋白I依赖性自身抗体与自然流产的关系

为探讨β2-糖蛋白I依赖性自身免疫抗体对自然流产病因诊断价值。将59名自然流产患者作为研究组,同时选择29名正常妊娠的产妇作为对照组。结论显示检测抗磷脂抗体能提高对自然流产患者病因诊断,β2-糖蛋白I依赖性抗心磷脂抗体的特异性较单纯抗心磷脂抗体的特异性高,诊断妊娠丢失的病因更准确。     

早发型重度子痫前期的诊疗决策

为探讨β2-糖蛋白Ⅰ依赖性自身免疫抗体对自然流产病因诊断价值。将59名自然流产患者作为研究组,同时选择29名正常妊娠的产妇作为对照组。结论显示检测抗磷脂抗体能提高对自然流产患者病因诊断,β2-糖蛋白Ⅰ依赖性抗心磷脂抗体的特异性较单纯抗心磷脂抗体的特异性高,诊断妊娠丢失的病因更准确。     

团体决策支持系统和团体讨论对团体决策的影响

通过模拟实验的方法,探讨了团体决策支持系统（GDSS）和团体讨论对团体决策的影响。以大学生为被试,运用小组决策任务,对小组决策过程进行了研究。实验记录了在有无GDSS的支持和有无团体讨论两个变量所决定的4种实验条件下,小组决策取得结果的正确性和组内的一致性。用ANOVA方法分析了4种条件下的实验结果,发现GDSS能提高团体决策的正确性,而团体讨论将有助于成员做出一个正确的、一致的决策     

语义问题与人工智能模型构造的系统观点

基于"物理符号系统假设"的传统人工智能采信了低阶结构不连续的思想,将概念化与概念的语义基础分离,把对思维过程的模拟看作是能用形式化方法来实现的。但事实证明,这种后验性方法存在理论和实现上的双重危机,要完成有实际意义的、有创新性的智能行为丰富的语义是必需的,这使语义问题成为人工智能不同应用分支中的焦点,它包括语义获取、表达和使用三个方面。而要实现对语义问题的认识和解决就必须把它和其它智能行为作为一个连续的、相关的、不可分割的认知结构进行完整地考察,以系统的观点来看待智能模型的构造问题。这个认知结构统一性的基石就是基于神经生理基础的、以知觉的心理生理学解释为依据的、对语义的直接表达,这为统一以神经系统动力学为模型的其它各种智能行为提供了基础。     

Personal Spiritual Values and Quality of Life: Evidence from Chinese College Students

Values are guiding principles in our life. While some studies found spiritual values to be “healthier,” Sagiv and Schwartz (Eur J Soc Psychol 30:177–198, 2000) showed that people holding non-spiritual values were higher on affective well-being. We examined the predictive power of these two types of values with a longitudinal data set collected from Chinese students mainly in Hong Kong. Structural equation modeling revealed that spiritual values (as well as family income) positively predicted quality of life a year later. Non-spiritual, self-enhancement values, did not show any association. Results suggest that developing spiritual values may promote well-being through enabling individuals to find meaning and purpose in life.     

Mortality salience and evaluations of in‐group versus out‐group critics: The role of criticism legitimacy and perceived threat

Significant terror management research has examined the impact of mortality salience on evaluations toward in‐group versus out‐group and attitudinally similar versus dissimilar others. However, relatively little research has examined evaluations when group membership is disentangled from attitude similarity. The current research examined the impact of mortality salience on evaluations toward in‐group and out‐group critics when people are less likely to rely on group membership as a heuristic. In Experiment 1, the results showed that in the control condition, participants rated an in‐group member who provided unjustified criticism more positively than an out‐group member who provided the same criticism. Under mortality salience, the reverse occurred: An in‐group member who provided unjustified criticism was rated more negatively than an out‐group member. Experiment 2 showed that under mortality salience, the derogation of an in‐group critic who provided unjustified criticism was mediated by perceptions of threat. Implications for reactions to group‐directed criticism as well as mortality salience effects are discussed. Copyright © 2014 John Wiley & Sons, Ltd.
