Who finds neutral pictures pleasant and relaxing?

Valence and arousal are independent dimensions of consciously experienced affect. The former refers to pleasantness; the latter to the degree of excitement or stimulation. The present research explores some of the predictors of these dimensions through the hypothesis that valence relates to positive affect and lack of negative affect, while arousal is tied to negative affect, and that both are predicted by personal wellbeing, considered as a way of achieving happiness. The occurrence of depressive symptoms is also considered within the hypothesis: as a facet of negative affect, as lack of wellbeing, or as an independent dimension placed at the same level as wellbeing, and which relates to both positive and negative affect (considered as mediators). Sixty-one participants were asked to view on a computer screen a series of 20 neutral pictures, having medium valence and low arousal, and complete self-report questionnaires to assess affect, personal wellbeing, and the occurrence of depressive symptoms. After picture viewing, valence and arousal judgments were requested. In the analysis, three competing models with latent variables were tested, to assess at best the role depressive symptoms have. They confirmed that valence is predicted by high positive and low negative affect, arousal by negative affect and even directly by the occurrence of depressive symptoms, and that personal wellbeing and depressive symptoms are the starting point. They are negatively correlated and predict positive (both) and negative affect (just the occurrence of depressive symptoms). The discussion focuses on both theoretical and practical implications. Suggestions for future research are given.     

特定句法提示对3－4岁儿童错误信念理解的影响

通过在错误信念任务中,为儿童提供关于错误信念表征的特定句法,考察这种句法理解对儿童的错误信念理解成绩是否有促进作用。124名3-4岁幼儿参加实验,每个年龄组幼儿随机分配到零级提示,一级提示和二级提示等三个句法提示条件组,并完成4个错误信念任务。结果发现,一级提示条件和二级提示条件下的错误信念理解成绩显著高于零级提示条件下的错误信念理解成绩,而一级和二级两种提示条件之间没有显著差异。句法提示对不同的错误信念任务的影响是相同的,对错误信念的预测问题和解释问题的影响模式是一致的。表明对错误信念表征的特定句法提示,有效促进了儿童的错误信念成绩,提示这种句法结构可能有助于儿童的错误信念理解     

目标焦点监控下目标信息的建构与整合

探讨文本阅读过程目标焦点监控下读者对目标信息的建构与整合。采用移动窗口技术,要求被试阅读24篇含有主人公目标的记叙文,设计了子目标未实现、子目标曲折实现或子目标直接实现三种条件,对不同条件下目标启动句阅读时间进行分析。实验1对子目标曲折实现与子目标未实现两种条件下目标启动句阅读时间进行比较,结果表明,曲折实现条件下目标启动句阅读时间长于未实现条件下目标启动句的阅读时间,说明在没有共振的情况下,目标启动句也可以激活先前的目标信息引发目标整合。实验2比较在子目标曲折实现与子目标直接实现条件对目标启动句阅读时间,以探讨在目标焦点条件下是否对相关信息进行追随性建构,结果表明,曲折实现条件下目标启动句阅读时间与直接实现条件下目标启动句的阅读时间差异不显著,说明在目标焦点监控下可以发生阅读信息的追随性建构。本实验结果初步证明,阅读不同文本信息可能会引发不同的信息加工活动,建构主义理论与记忆基础文本加工理论都只是说明了文本阅读信息加工的一个侧面。     

College students' perceived risk and anxiety after reading airplane crash news

328 college students in midwest and west coast regions read one of five news stories (four airplane crash and one irrelevant) or none. They estimated the likelihood of their victimization in an airplane crash and indicated the maximum amount of time that they would be willing to spend driving in lieu of flying. Analysis showed those who read one of the airplane crash stories reported higher perceived risk of victimization than did those who read the irrelevant story or none. Reading airplane crash news was not related to the number of hours reported for driving instead of flying.     

Relations of perceived ethnic disparity to involvement in ethnic and host cultures

Among 124 single foreign students residing in the USA, this study examined the relations between perceived ethnic disparity, consisting of physical, cultural. and linguistic dimensions, and ethnic and host culture involvement. The Ethnic Disparity Perception Inventory, a 44-item Likert scale devised to measure perceived ethnic disparity, showed perceived physical disparity (r = .60) and cultural disparity (r = .51) were positively related to ethnic involvement. Perceived cultural disparity (r = -.22) and linguistic disparity (r = -.27) were negatively associated with involvement in the host culture. Multiple regression analysis indicated that, although the findings held for non-White respondents, for White respondents (n = 39) perceived physical disparity (beta = .54), not cultural disparity, was a significant predictor of ethnic involvement (Adjusted R2 = .268) and perceived cultural disparity (beta = -.37), not linguistic disparity, was a significant (negative) indicator of host culture involvement (Adjusted R2 = .110).     

英语句法歧义消解过程中基于激发点的权变模型

采用自控速度的移动窗口技术,在3个实验中分别考察句法歧义消解的基本过程。阅读材料为不含有词汇歧义的较为单纯的英语句法歧义句。结果为：实验1的研究结果表明在语料中不存在歧义激发点的情况下,被试不会启动歧义的消解过程;实验2的研究结果表明当歧义激发点与解歧区重合时,人们会选用再分析机制来处理解歧区语料;实验3的研究结果表明当歧义激发点与歧义区重合时,人们会选用竞争机制来处理歧义区语料。本研究初步验证了基于激发点的权变模型关于句法歧义消解过程的相关设想。     

Vocal emotions influence verbal memory: Neural correlates and interindividual differences

Past research has identified an event-related potential (ERP) marker for vocal emotional encoding and has highlighted vocal-processing differences between male and female listeners. We further investigated this ERP vocal-encoding effect in order to determine whether it predicts voice-related changes in listeners’ memory for verbal interaction content. Additionally, we explored whether sex differences in vocal processing would affect such changes. To these ends, we presented participants with a series of neutral words spoken with a neutral or a sad voice. The participants subsequently encountered these words, together with new words, in a visual word recognition test. In addition to making old/new decisions, the participants rated the emotional valence of each test word. During the encoding of spoken words, sad voices elicited a greater P200 in the ERP than did neutral voices. While the P200 effect was unrelated to a subsequent recognition advantage for test words previously heard with a neutral as compared to a sad voice, the P200 did significantly predict differences between these words in a concurrent late positive ERP component. Additionally, the P200 effect predicted voice-related changes in word valence. As compared to words studied with a neutral voice, words studied with a sad voice were rated more negatively, and this rating difference was larger, the larger the P200 encoding effect was. While some of these results were comparable in male and female participants, the latter group showed a stronger P200 encoding effect and qualitatively different ERP responses during word retrieval. Estrogen measurements suggested the possibility that these sex differences have a genetic basis.
