自闭症谱系障碍者面孔识别的神经机制

自闭症谱系障碍（ASD）是一种心理状况的谱系障碍,其症状是社交及沟通上的广泛性异常、异常局限性的兴趣和高度重复性的刻板行为。包括自闭症、亚斯伯格症候群和待分类的广泛性发展障碍3类。研究主要以事件相关电位和功能性磁共振成像两种技术为线索,通过深入分析ASD患者在面孔识别认知过程中脑的异常变化,探讨其面孔识别障碍的神经机制问题。研究表明,ASD患者面孔识别能力的损伤主要与N170、N300、P400和Nc等ERPs成份异常及梭状回面孔区和杏仁核的低激活有关。研究推论ASD患者面孔识别障碍是多个异常脑区联合作用的结果,且主要受异常脑区的数量和损伤程度的影响。     

自动情绪调节对负性情绪面孔注意偏向的影响

本研究通过成语匹配任务启动情绪调节目标,在情绪flanker任务中考察了自动情绪调节启动对注意偏向的影响。结果表明,中性启动条件下,被试表现出对负性情绪面孔的注意偏向,而情绪调节启动条件下,被试对正性、负性情绪面孔的注意分配不存在显著差异。这一结果说明自动情绪调节可以有效地减弱被试的负性情绪面孔注意偏向。

Cultural worldviews and climate change: A view from China

We investigated the association between cultural worldviews and climate change risk perceptions, support for climate friendly policies and climate change mitigation behaviours in a large Chinese sample. Items from Dake's cultural theory scales and Kahan's cultural cognition scale were presented to a Qualtrics online panel consisting of 515 Mandarin‐speaking residents of Beijing. A series of factor analyses revealed that the combined item sets were best represented by four‐dimensions: hierarchism, individualism, egalitarianism and fatalism. Mediation analysis revealed that respondents with egalitarian and non‐fatalist worldviews perceived greater risk associated with climate change, which in turn predicted greater support for policies to manage climate change and increased mitigation behaviour. In addition, respondents who scored high on individualism were less likely to support climate change policies, but this effect was not mediated by risk perceptions. Overall, our results suggest cultural worldviews may influence policy support both directly and indirectly through risk perceptions.     

Counterfactual comparison modulates fairness consideration in the mini‐ultimatum game: An event‐related potentials study

Existing literature on the mini‐ultimatum game indicates that counterfactual comparison between chosen and unchosen alternatives is of great importance for individual's fairness consideration. However, it is still unclear how counterfactual comparison influences the electrophysiological responses to unfair chosen offers. In conjunction with event‐related potentials’ (ERPs) technique, the current study aimed to explore the issue by employing a modified version of the mini‐ultimatum game where a fixed set of two alternatives (unfair offer vs. fair alternative, unfair vs. hyperfair alternative, unfair offer vs. hyperunfair alternative) was presented before the chosen offer. The behavioral results showed that participants were more likely to accept unfair chosen offers when the unchosen alternative was hyperunfair than when the unchosen alternative was fair or hyperfair. The ERPs results showed that the feedback‐related negativity (FRN) elicited by unfair chosen offers was insensitive to the type of unchosen alternative when correcting for possible overlap with other components. In contrast, unfair chosen offers elicited larger P300 amplitudes when the unchosen alternative was hyperunfair than when the unchosen alternative was fair or hyperfair. These findings suggest that counterfactual comparison may take effect at later stages of fairness consideration as reflected by the P300.     

默读和出声阅读的副中央凹预视效应

以往研究大多考察默读中是否存在副中央凹预视效应及存在何种类型的预视效应,很少有研究探讨出声阅读中的副中央凹预视效应以及阅读中预视信息提取的时间进程。本研究采用边界范式,通过两个眼动实验考察默读和出声阅读中的副中央凹预视效应及预视信息提取的时间进程。实验1发现在默读和出声阅读中都存在副中央凹预视效应,但是默读中副中央凹预视效应更大。实验2发现出声阅读中在注视中央凹词汇的早期不能提取副中央凹处信息。两个实验的结果表明默读和出声阅读条件下的副中央凹加工是不同的,需要用不同的眼动模型解释。     

中文阅读中长距离回视引导机制的眼动研究

从记忆的角度,探讨中文阅读中长距离回视的引导机制。采用眼动实验,操纵了回视条件(实验1)、回视可见性(实验2)、目标词位置及词频变量。结果发现:与不阅读组相比,阅读组的最初回视误差更小,定位效率更高;与可见组相比,不可见组累积回视距离更大,且难以正确定位目标;目标词位置主效应显著,而词频主效应不显著。结果表明,回视具有空间选择性,最初的回视由空间记忆引导,最初回视后的修正眼跳在文本可见情况下才能正常进行,而词频这一言语属性对回视没有显著影响,本研究结果支持了空间编码假设。     

主观幸福感的结构及其与人格特质的关系

以239名大学生为被试,考察了主观幸福感(SWB)的结构及其与人格特质的关系。分析表明,SWB由生活满意度、积极情感和消极情感三个相关的维度构成,而且它们可以共同负荷于一个高阶因子。外倾和神经质是SWB的重要预测指标,积极情感的主要预测指标是外倾,神经质则是消极情感最有力的预测指标,而外倾和神经质对消极情感和生活满意度有相同的预测力。情感平衡是外倾和神经质影响生活满意度的中介变量。     

假言推理的否定词效应

介绍假言推理中的4种否定词效应,以及相关的理论模型。被试在进行假言推理时,对前提或结论所表示的事件加进了否定词, 产生了一系列的心理效应。研究发现,范畴前提含有否定词,被试更难做出正确的推论;如果结论中含有否定词,被试却更容易做出正确的推论。为此,心理模型理论,规则理论,概率模型理论以及我国的学者对该问题都作了研究和阐述。
