用于项目生成的认知模型的构建与比较——以矩阵完成问题为例

项目生成是一种新的测验编制技术,它可以弥补传统测验编制技术的缺陷.使用该技术编制测验,要进行大量的前期工作,如必须要了解和归纳所编测验中项目的所有刺激特征,据此建立认知模型,再将认知模型与心理计量模型联合,构建能预测新生成项目难度的数学模型等.该研究以矩阵完成问题为例,在带约束的两参数Logistic模型的基础上,通过对构建的几个认知模型的比较,挑选合适的认知模型为矩阵完成问题的项目生成研究服务.研究结果表明,自建的认知模型能够满足矩阵问题项目生成的要求.     

白玉蟾融通三教之内丹性命思想论析

金丹派南宗第五祖白玉蟾以丹论名著于世,融通三教是其内丹性命思想的最突出特征之一。他援儒入道,摄禅融老,强调炼形以养神、明心见性以合道,究其实质是欲以道为本,融合三教思想于一炉,锻造出更为成熟圆融的内丹性命论。故其丹学呈现出圆熟、简要、通俗等特点,对后学影响深远,并对于南宗内丹学的实践与传播,以及南宗教派的发展壮大具有重要意义。     

论自然律与因果知识的知觉经验基础

<正>一、引论自休谟以来,特别是在科学哲学的演进中,自然律理论与因果理论从来是不可分离的。相比而言,自然律理论具有某种优先地位。因为按照休谟的广为接受的论证,人类的知觉经验并不能直接辩     

解释水平在社会距离影响具身模拟中的中介效应检验

具身认知理论及相关的脑研究显示,个体在推断他人心理时具身模拟的强度可能会受到社会距离的影响。基于解释水平理论和具身认知理论,通过两项实验室实验探讨社会距离的外部线索—人格相似性和内外群关系对具身模拟强度的影响。结果显示:社会距离越近,个体的解释水平越低,具身模拟强度越高;解释水平可以部分中介人格相似性对具身模拟的影响,中介效应占总效应量的38.4%;解释水平可以完全中介内外群线索对具身模拟的影响。最后,结合实验结果讨论了个体推断他人心理的过程和机制。     

丹尼特的“异类现象学”——新实用主义谱系中一个被忽略的环节

一般认为,"新实用主义"乃经典实用主义的一个后现代主义的变种,它无法在知识论的角度接受心灵表征的客观实在性。本文则认为,反实在论并非是我们发展实用主义的心灵哲学时必然陷入的理论窠臼。如果我们采纳美国哲学家丹尼特主张的"异类现象学"方法,我们就有可能将科学方法和工具主义立场相调和,或在对他人的心灵状态做出本体论承诺时,不必向反实在论投降。     

The Effects of a Summer Camp Program in China on Children's Knowledge,Attitudes, and Behaviors Toward Animals: A Model for Conservation Education

ABSTRACT

This summative evaluation, conducted in Chengdu, Sichuan Province, China, studied whether participation in a conservation education camp positively changed 8–12-year-old children's (a) knowledge of how to protect animals, (b) care about animals, (c) propensity for environmental and wildlife stewardship, and (d) compassionate behavior toward animals and nature. Influenced by conservation psychology, social learning theory, empathy and moral development, constructivism, and conservation biology, 5-day overnight camps were conducted at 2 zoological institutions. Activities were designed to help children form bonds with animals and care enough to positively change their behavior toward animals and nature. Mixed methods, using pre- and postvisit surveys, researcher field notes, vignettes, student journals, an end of camp questionnaire, and a camper behavior ethogram, revealed significant increases in knowledge, care, and propensity for action, and an additional theme, empathy. This study identified effective strategies to promote positive behavior toward animals, empathy, and conservation behavior.     

Association of Dopamine D2 Receptor Gene with Creative Ideation

Although several studies suggest that dopamine D2 receptor (DRD2) gene may contribute to creativity, the relationship between DRD2 and creativity still needs to be further validated. To further test the relevance of DRD2 and creativity, this study explored the association between DRD2 and creative ideation in 483 unrelated healthy Chinese undergraduate students. A total of 15 single nucleotide polymorphisms (SNPs) covering the DRD2 were genotyped, and creative ideation was assessed by the Runco Ideational Behavior Scale (RIBS). Single SNP analysis showed that 2 SNPs (rs4648317 and rs4938019) were nominally associated with fluency, 4 SNPs (rs4648317, rs4938019, rs4648319, and rs1800497) were nominally associated with flexibility, and 1 SNP (rs4648317) was nominally associated with originality. Haplotype analysis showed several haplotypes were nominally associated with various creative ideation indexes. However, none of these nominal associations survived correction for multiple testing. Overall, this study provides suggestive evidence for the genetic impact of DRD2 on creative ideation and supports the assumption that the genotype variations in DRD2 contribute to creativity.     

Argument by Multimodal Metaphor as Strategic Maneuvering in TV Commercials: A Case Study

Drawing on insights from contemporary studies on conceptual metaphor and multimodal metaphor, the present study proposes a tentative analysis of multimodal metaphorical argument from the perspective of the extended theory of pragma-dialectics. A case, Liqun Commercial, is presented as an illustration. This commercial proves to use a conceptual metaphor, life is a journey, that underlies a multimodal metaphorical argument. The conceptual metaphor is highly acceptable in the cultural context of the Chinese target audience. Due to the restrictions imposed by the institutional context, the commercial tries to convince the audience by using implicit argumentative means. In this endeavor, multimodal metaphorical argument is used to enhance the commercial’s effectiveness by foregrounding through framing the aspects the protagonist desires to show and by using a strategy to evade sanctions for ignoring institutional constraints.     

Leadership predictors of innovation and task performance: Subordinates' self‐esteem and self‐presentation as moderators

This study examined self‐related subordinate variables as moderators of relationships between supervisors' leadership behaviours (transformational as well as active‐corrective transactional leadership) and subordinates' innovative behaviour and task performance. Based on behavioural plasticity and self‐monitoring theory, we hypothesized that these associations would be moderated by subordinates' organization‐based self‐esteem and by their propensity to modify self‐presentation, a major facet of the self‐monitoring construct. Field survey data (N=161) collected in research and development, marketing and human resources departments of several German companies revealed that transformational leadership positively predicted both criteria, whereas active‐corrective transactional leadership negatively predicted innovation. As hypothesized, transformational leadership related more strongly and positively to innovation for subordinates low in organization‐based self‐esteem. When subordinates were low in self‐presentation propensity, active‐corrective transactional leadership was negatively, and transformational leadership was positively associated with task performance.     

Multiple trajectories of depressive symptoms in middle and late life: racial/ethnic variations

This research aims to identify distinct courses of depressive symptoms among middle-aged and older Americans and to ascertain how these courses vary by race/ethnicity. Data came from the 1995-2006 Health and Retirement Study which involved a national sample of 17,196 Americans over 50 years of age with up to six repeated observations. Depressive symptoms were measured by an abbreviated version of the Center for Epidemiologic Studies Depression scale. Semiparametric group based mixture models (Proc Traj) were used for data analysis. Six major trajectories were identified: (a) minimal depressive symptoms (15.9%), (b) low depressive symptoms (36.3%), (c) moderate and stable depressive symptoms (29.2%), (d) high but decreasing depressive symptoms (6.6%), (e) moderate but increasing depressive symptoms (8.3%), and (f) persistently high depressive symptoms (3.6%). Adjustment of time-varying covariates (e.g., income and health conditions) resulted in a similar set of distinct trajectories. Relative to White Americans, Black and Hispanic Americans were significantly more likely to be in trajectories of more elevated depressive symptoms. In addition, they were more likely to experience increasing and decreasing depressive symptoms. Racial and ethnic variations in trajectory groups were partially mediated by SES, marital status, and health conditions, particularly when both interpersonal and intrapersonal differences in these variables were taken into account.
