气质和儿童同伴交往类型关系的研究

该文采用问卷法和社会测量法相结合的方法,以班级为单位对484名3~9岁儿童的气质和同伴关系类型的关系进行研究。结果表明:3~9岁儿童同伴关系类型已形成分化,其中被忽视儿童和被拒绝儿童所占总体样本的比例分别为16.9%和9.6%,比例较高值得重视。儿童气质对同伴交往类型的形成影响很大,四种同伴关系交往类型在气质各维度上方差检验都达到了差异显著,有着明显不同的气质特点。     

小学儿童空间物体位置编码（Ⅰ）

采用找物范式研究小学7、9、11岁儿童利用点与点之间的关系对目标物位置进行编码的认知发展。结果表明：两点距离编码和三点共线编码认知成绩的年龄效应显著,9岁组和11岁组儿童的认知成绩显著好于7岁组儿童的认知成绩。两个不同实验任务对儿童认知成绩的影响不同,7岁组儿童两点距离编码认知成绩显著好于三点共线编码认知成绩,9岁组和11岁组两个任务的认知成绩差异不显著。提供编码线索后,认知成绩有了较大的改善。     

幼儿对数的认知及其策略

该研究探查幼儿对基数、数序、运算和解应用题的认知发展过程及其认知策略。着重探查：(1)不同认知任务对幼儿数认知发展的影响;(2)幼儿对基数和数序两者认知发展的顺序;(3)从幼儿主动解决问题的策略探究其认知发展水平。该研究采用定性和定量相结合的研究方法。被试为4、5、6岁城市幼儿园儿童,共92人,男女约各半。全部实验以个别方式进行。主要研究结果表明：(1)幼儿对基数、数序、运算和解应用题的认知成绩均有随年龄发展的趋势,但快速发展的年龄阶段因任务的难度而异;(2)幼儿对基数和数序的认知在4—5岁显示出不同步的发展,对基数的认知成绩优于对数序的认知,而到6岁两者具有同步发展的趋势;(3)幼儿解决问题的策略水平随年龄发展,显示了由外化水平的智力活动向完全内化的智力操作的发展过程,并具有明显的层次性。该研究结果为幼儿数能力的培养和促进提供参考依据。     

自我损耗：理论、影响因素及研究走向

自我的活动消耗心理能量后引起执行功能下降的过程称为自我损耗, 自我损耗是生活中诸多的适应不良现象的原因之一。近几年, 自我损耗理论在发生领域、损耗状态的时限和内在机制等方面均有所发展; 对自我损耗影响因素的探究主要集中于认知、情绪及人格特质等领域; 自我损耗后效的研究逐渐呈现出应用化的趋势。未来研究需要进一步探究自我损耗的机制, 对影响因素和损耗后效上存在的争议进行澄清, 并在测量工具上寻找突破以满足理论的发展需求。     

Modeling general and specific variance in multifaceted constructs: a comparison of the bifactor model to other approaches

This article recommends an alternative method for testing multifaceted constructs. Researchers often have to choose between two problematic approaches for analyzing multifaceted constructs: the total score approach and the individual score approach. Both approaches can result in conceptual ambiguity. The proposed bifactor model assesses simultaneously the general construct shared by the facets and the specific facets, over and above the general construct. We illustrate the bifactor model by examining the construct of Extraversion as measured by the Revised NEO Personality Inventory (NEO‐PI‐R; Costa & McCrae, 1992), with two college samples (N = 383 and 378). The analysis reveals that the facets of the NEO‐PI‐R Extraversion correlate with criteria in opposite directions after partialling out the general construct. The direction of gender differences also varies by facets. Bifactor models combine the advantages but avoid the drawbacks of the 2 existing methods and can lead to greater conceptual clarity.     

中等强度情绪性图片的神经机制——一项fMRI研究

采用修订后的中等唤起度的国际情绪图片为刺激材料,以12名女性大学生为被试,考察情绪性图片引起的脑激活模式。结果发现,与中性条件相比,消极情绪图片激活了枕叶、杏仁核、海马旁回和壳核。积极情绪图片引起枕叶、内侧眶额、额中回等脑区的激活,研究结果再次验证了杏仁核与消极情绪的密切关系,同时推测,内侧眶额可能是中等唤起度的趋近性积极情绪的一个脑功能区。     

Communication behavior and relationship satisfaction among American and Chinese newlywed couples

Most research on couple communication patterns comes from North America and Europe and suggests cross-cultural universality in effects, but emerging studies suggest that couple communication takes different forms depending on the cultural context in which it occurs. The current study addressed this discrepancy by comparing the observed social support behaviors of 50 newlywed American couples and 41 newlywed Mainland Chinese couples, first on mean levels of positivity and negativity and second on behavior-satisfaction associations. Consistent with predictions derived from observational work by Tsai and Levenson (1997), Chinese couples were observed displaying significantly more negative behavior than American couples, even after controlling for relationship satisfaction; the 2 groups did not differ in observed positive behaviors. Tests of the moderating role of culture on behavior-satisfaction associations showed that positivity was significantly related to relationship satisfaction only for American husbands, whereas negativity was significantly associated with relationship satisfaction only for Chinese husbands. We speculate that cultural contexts may influence the display and evaluation of behavior in intimate relationships, suggesting the need for caution when generalizing models and associated interventions to non-Western couples.     

语言理解转换中非目标语言影响目标语言的时间进程

运用跨语言即时启动和延时启动范式,要求被试完成生物属性的语义判断任务,研究语言理解转换中非目标语言影响目标语言语义理解的时间进程。实验1非目标语言为英文,目标语言为中文,结果表明,无论是即时启动(t = -0.423, p = 0.676),还是延时启动(t = -0.82, p = 0.419),语义相关组与语义无关组都无显著差异。实验2非目标语言为中文,目标语言为英文,结果表明,在即时启动条件下,语义相关组显著快于语义无关组(t = -3.05, p = 0.006),但延时条件下语义相关组与语义无关组无显著差异(t = -0.63, p = 0.536)。综合两个实验结果表明,晚期熟练双语者在双语语言理解转换过程中语义的即时启动影响存在不对称性,语义相关的非目标语言中文对目标语言英文语义理解起促进作用;但是语义启动效应没有得到延时体现。     

不确定性、情绪对公正判断的影响

本研究以不确定管理模型为理论来源,采用实验法探讨了公正判断中的情绪效应。实验1采用2（两种情绪状态：愉快/愤怒）×4（四种结果：比自己多/一样多/比自己少/不知道）被试间设计。实验2采用2（两种情绪状态：愉快/愤怒）×3（三种程序：有发言权/外显无发言权/无发言权信息）被试间设计。分别考察了分配公正与程序公正判断中的情绪影响。结果发现：不确定性调节了情绪与公平判断之间的关系。当用于公平判断的外部信息不明确时,情绪充当了公平判断的线索。
