Promoting Honesty: The Influence of Stories on Children's Lie‐Telling Behaviours and Moral Understanding

Moral stories are a means of communicating the consequences of our actions and emphasizing virtuous behaviour, such as honesty. However, the effect of these stories on children's lie‐telling has yet to be thoroughly explored. The current study investigated the influence of moral stories on children's willingness to lie for another individual. Children were read one of three stories prior to being questioned about an accidental wrongdoing: (1) a positive story, which emphasized the benefits of being honest; (2) a negative story, which outlined the potential costs of lying; and (3) a neutral story, which was unrelated to truth‐telling or lie‐telling. Initially, most children withheld information about the event. Older children were better able to maintain their lies throughout the interview. However, when asked direct questions, children in the positive story condition were more likely to tell the truth than those in the negative and neutral conditions. No significant differences were found between the negative and neutral story conditions. The present study also investigated the relationship between children's conceptual understanding and behaviour. The findings revealed that children's knowledge of truths and lies increased with age. Children who lied had significantly higher conceptual scores than those who did not lie. Furthermore, the type of story children were read had a significant impact on their evaluations of true and false statements. Copyright © 2015 John Wiley & Sons, Ltd.     

Projectibility and Explainability or How to Draw a New Picture of Inductive Practices

Summary  Goodman published his “riddle” in the middle of the 20th century and many philosophers have attempted to solve it. These attempts almost all shared an assumption that, I shall argue, might be wrong, namely, the assumption that when we project from cases we have examined to cases we have not, what we project are predicates (and that this projectibility is an absolute property of some predicates). I shall argue that this assumption, shared by almost all attempts at a solution, looks wrong, because, in the first place, what we project are generalizations and not predicates, and a generalization is projectible (or unprojectible) relative to a given context. In this paper I develop the idea of explainable–projectible generalizations versus unexplainable–unprojectible generalizations, relative to a specific context. My main claim is that we rationally project a generalization if and only if we rationally believe that there is something that explains the general phenomenon that the generalized statement in question asserts to obtain, and that a generalization is projectible, if and only if its putative truth can be explained, whether we know that it can be or not.     

立体结构特异性逆翻译酶与免疫信号的传递

分子遗传学中心法则提示,遗传信息由蛋白质向ＤＮＡ的输入过程在蛋白质和ＲＮＡ之间是断开的。而获得性特异性免疫反应的产生却意味着机体遇到外来抗原入侵后存在信息增加的过程。本文由此假设：１存在立体结构特异性逆翻译酶,介导信息由蛋白质向ＲＮＡ的传递;２特异性免疫应答形成过程中,逆翻译酶按外来抗原的空间结构合成针对外来抗原的基因片段,是免疫特异性形成的核心     

Induction of Relational Schemas: Common Processes in Reasoning and Complex Learning

Five experiments were performed to test whether participants induced a coherent representation of the structure of a task, called a relational schema, from specific instances. Properties of a relational schema include: An explicit symbol for a relation, a binding that preserves the truth of a relation, potential for higher-order relations, omnidirectional access, potential for transfer between isomorphs, and ability to predict unseen items in isomorphic problems. However relational schemas are not necessarily coded in abstract form. Predictions from relational schema theory were contrasted with predictions from configural learning and other nonstructural theories in five experiments in which participants were taught a structure comprised of a set of initial-state,operator → end-state instances. The initial-state,operator pairs were presented and participants had to predict the correct end-state. Induction of a relational schema was achieved efficiently by adult participants as indicated by ability to predict items of a new isomorphic problem. The relational schemas induced showed the omnidirectional access property, there was efficient transfer to isomorphs, and structural coherence had a powerful effect on learning. The “learning to learn” effect traditionally associated with the learning set literature was observed, and the long-standing enigma of learning set acquisition is explained by a model composed of relational schema induction and structure mapping. Performance was better after reversal of operators than after shift to an alternate structure, even though the latter entailed more overlap with previously learned tasks in terms of the number of configural associations that were preserved. An explanation for the reversal shift phenomenon in terms of induction and mapping of a relational schema is proposed. The five experiments provided evidence supporting predictions from relational schema theory, and no evidence was found for configural or nonstructural learning theories.     

刺激结构对视觉定位的影响

本实验采用多点定位作业,结合部分报告法,研究视觉刺激的整体结构对定位成绩的影响。所呈现的刺激为1、2、3或4个颜色点。其中2、3、4点刺激分别是直线、正三角形和正方形。结果发现,当呈现时间较长时,1点和2、3、4点的定位误差无显著差异。但是1点的定位反应时却显著少于2、3、4点。这提示出现视觉定位的结构效应。而当呈现时间较短时,却没有这种结构效应。实验还发现,这种结构效应并不因刺激结构的不同而有区别。     

特征归纳的关联相似性模型

作者提出特征归纳的关联相似性模型,用以描述以归纳特征的关联特征相似性为基础的归纳推理,把归纳推理中相似性和关联知识统一整合起来。该模型认为归纳强度主要取决于归纳特征与关联特征的关联强度和关联特征的相似性程度的乘积,归纳信心主要取决于关联强度,从而分离归纳信心和归纳强度。以大学生为被试的两个实验的主要结果支持关联相似性模型的主要预测。关联相似性模型能够描述解释以关联特征相似性为基础的归纳推理现象,比以往的归纳理论具有更大的解释能力和解释范围     

Why are some people more susceptible to ingroup threat than others? The importance of a relative extrinsic to intrinsic value orientation

Whereas an individual differences perspective recently pointed to the importance of a relative extrinsic to intrinsic value orientation in the prediction of outgroup attitudes, the intergroup relations perspective stresses the importance of threat. This study investigates the interplay of both perspectives. A scenario study among high-school students showed that only people who attach greater relative importance to extrinsic values react with a negative attitude towards an outgroup that is portrayed as threatening. A longitudinal study among university students then showed that people with a relatively greater extrinsic value orientation are not only more likely to react to threat but also to perceive threat. Specifically, cross-lagged analyses showed that a relatively greater extrinsic value orientation predicted over-time increases in threat perceptions.     

What difference reveals about similarity

Detecting that two images are different is faster for highly dissimilar images than for highly similar images. Paradoxically, we showed that the reverse occurs when people are asked to describe how two images differ--that is, to state a difference between two images. Following structure-mapping theory, we propose that this disassociation arises from the multistage nature of the comparison process. Detecting that two images are different can be done in the initial (local-matching) stage, but only for pairs with low overlap; thus, "different" responses are faster for low-similarity than for high-similarity pairs. In contrast, identifying a specific difference generally requires a full structural alignment of the two images, and this alignment process is faster for high-similarity pairs. We described four experiments that demonstrate this dissociation and show that the results can be simulated using the Structure-Mapping Engine. These results pose a significant challenge for nonstructural accounts of similarity comparison and suggest that structural alignment processes play a significant role in visual comparison.
