吗啡行为及条件性行为敏感化效应及其个体差异

目的：考察吗啡处理下,大鼠行为敏感化及条件性行为敏感化效应及其个体差异性表现。方法：根据大鼠在初次抵达的新颖环境中水平活动量的高低,将大鼠划分为高反应大鼠（High responder, HR）和低反应大鼠（Low responder, LR）,应用自动监测大鼠活动箱,分别考察HR和LR大鼠在行为及条件性行为敏感化效应表达上的差异。结果：（1）连续5天吗啡给药,LR大鼠活动量显著升高,HR大鼠无此效应;（2）条件测试日（第6天）,给药与环境匹配大鼠,活动量较给药与环境非匹配组动物和对照组动物显著为高;此效应在HR和LR大鼠同时存在;（3）从给予吗啡到给予盐水,发现LR大鼠活动量显著下降,而HR大鼠活动量无显著改变。结论：在连续给药下,LR大鼠较HR大鼠,在行为敏感化效应的形成中,具有更为显著的效应,此效应为LR动物对吗啡更高的药物效应,而非条件效应所致,同时HR和LR大鼠都可以对吗啡条件性线索产生应答,产生条件性行为敏感化效应。     

四则混合运算规则的样例学习

采用有或无“运算步骤标记”两种样例和“交互式”样例呈现方式,对48名二年级小学生通过样例学习四则混合运算规则进行了实验。结果表明,多数被试可以通过样例学会“小括号”和“中括号”四则混合运算规则,但多数被试难以学会“无括号”四则混合运算规则;运算步骤标记对学习“无括号”运算规则的促进作用明显,但对学习“小括号”运算规则的促进作用不明显;运算规则学习的难度不同,所需样例的数量也不同。     

Racing dragons and remembering aliens: Benefits of playing number and working memory games on kindergartners' numerical knowledge

Sources that contribute to variation in mathematical achievement include both numerical knowledge and general underlying cognitive processing abilities. The current study tested the benefits of tablet‐based training games that targeted each of these areas for improving the mathematical knowledge of kindergarten‐age children. We hypothesized that playing a number‐based game targeting numerical magnitude knowledge would improve children's broader numerical skills. We also hypothesized that the benefits of playing a working memory (WM) game would transfer to children's numerical knowledge given its important underlying role in mathematics achievement. Kindergarteners from diverse backgrounds (n = 148; 52% girls; M_age = 71.87 months) were randomly assigned to either play a number‐based game, a WM game, or a control game on a tablet for 10 sessions. Structural equation modeling was used to model children's learning gains in mathematics and WM across time. Overall, our results suggest that playing the number game improved kindergarten children's numerical knowledge at the latent level, and these improvements remained stable as assessed 1 month later. However, children in the WM group did not improve their numerical knowledge compared to children in the control condition. Playing both the number game and WM game improved children's WM at the latent level. Importantly, the WM group continued to improve their WM for at least a month after playing the games. The results demonstrate that computerized games that target both domain‐specific and domain‐general skills can benefit a broad range of kindergarten‐aged children.     

偏差声音干扰刺激对视觉注意网络系统的影响

结合注意网络测量工具和听视ODDBALL干扰范式,考察偏差声音干扰刺激的出现对注意网络系统不同功能的影响。结果发现,声音刺激序列下,视觉线索唤醒效应均消失; 标准声音刺激下,不存在线索的脱离和转移效应; 偏差声音刺激下,出现线索脱离和转移效应。研究表明,注意网络中的警觉功能具有超通道加工机制,偏差刺激下视觉注意系统中注意定向和线索转移效应的出现表明偏差干扰效应主要由偏差刺激引起的注意脱离和注意转移损耗部分引起。     

高中生感知教师支持与学习投入的关系:学业自我效能感和成就目标定向的链式中介作用

采用感知教师支持、学习投入、学业自我效能感和成就目标定向问卷对498名高中生进行问卷调查,探讨感知教师支持对学习投入的影响,以及学业自我效能感和成就目标定向的链式中介效应。结果显示：（1）感知教师支持能通过学业自我效能感间接预测高中生学习投入,感知教师支持可以通过掌握趋近、表现趋近、表现回避间接预测高中生学习投入;（2）学业自我效能感→掌握趋近、学业自我效能感→表现趋近、学业自我效能感→表现回避三者分别在感知教师支持与学习投入之间起链式中介作用,学业自我效能感→掌握回避的中介效应则不显著。上述结果表明,感知教师支持不仅能分别通过学业自我效能感、掌握趋近、表现趋近、表现回避预测高中生学习投入,还能通过学业自我效能感和成就目标定向的链式中介作用间接预测高中生学习投入。     

Filial piety dilemma solutions in Chinese adult children: The role of contextual theme,filial piety beliefs,and generation

Although some studies have revealed that traditional filial piety belief is weakening, few have explored whether and how the role of the belief in social life has changed correspondingly. The present study used questionnaires to examine solutions to filial piety dilemmas and the roles of contextual theme, filial piety beliefs, and generation in a sample of 123 young and 92 middle‐aged Chinese adults. With respect to the solutions adopted to solve parent?child conflicts, preferences varied depending on the dilemma themes. Specifically, participants were more likely to select a self‐sacrifice (rather than an ego‐centered) solution for respect dilemmas than for caring dilemmas, and least likely to do so for obedience dilemmas. Participants were also likely to select a balancing (rather than an ego‐centered) solution for respect or caring dilemmas than for obedience dilemmas. In addition, the concordance between beliefs and solutions was exhibited in reciprocal, but not authoritarian, filial piety beliefs. Individuals with stronger reciprocal filial piety beliefs were more likely to select self‐sacrifice or balancing solutions than ego‐centered solutions whereas authoritarian filial piety showed no influence on solutions for either young or middle‐aged adults. Furthermore, the generation effect was not significant, and the solution selection did not differ between young and middle‐aged adults.     

情绪预测偏差的成因及干预

情绪预测偏差是一种对未来事件发生时情绪反应的预测和实际体验之间的分离现象。梳理该领域最近10年(2009~2019年)研究文献可知, 热点研究主题涉及偏差的现象、成因和干预, 相应呈现为三点主要发现: 情绪预测偏差十分普遍, 情绪预测偏差成因多源, 情绪预测偏差可以干预。未来研究应着力关注情绪预测偏差的发生模式和心理机制, 着力揭示具体偏差的神经心理机制, 并从进化和文化视角综合考察偏差的发生机制。     

Toward a Multi-Layered Chiasme-Focused Topology: A Reading of Merleau-Ponty’s Later Writings

This paper traces the genealogy of reversibility, chiasma, and chiasme in Merleau-Ponty’s writings and offers a new characterisation of his later ontology in terms of a multi-layered chiasme-focused topology informed by subtle differences and interconnections among these notions. We need to grasp the significance of reversibility not only in terms of constant recoil and impossible overlap but also of its situatedness in the crisscrossing between Dasein and things, and between the inside/invisible and the outside/visible. “Chiasma” was initially introduced as a reference to the intersection of perspectives. Merleau-Ponty deploys it to articulate macroscopic insights concerning the nature of philosophy and the interweaving connections between self, other, and the world. In comparison, “reversibility” is primarily used to describe the microscopic bond between touching-touched and perceiving-perceived. I argue that, as Merleau-Ponty’s ultimate choice of wording, “chiasme” incorporated the significance of both “reversibility” and “chiasma.” A chiasme-focused topology that retains the significance of all three of the terms would serve to better convey the import of Merleau-Ponty’s later ontology, which aims to dissolve and to re-configure our conceptions about being, body, self, and the other from within and from below.     

传承动机对金融冒险行为的影响:未来自我连续性的中介

人们普遍拥有“期待不朽、被人铭记”的传承动机, 文章通过4个实验探讨了该动机如何通过未来自我连续性的影响作用于个体的金融冒险行为。实验1发现传承动机能够提升个体对未来自我的连续性感知。实验2在此基础上发现传承动机会弱化个体金融冒险行为(2a), 并且该效应被自我连续性感知中介(2b)。实验3进一步考察个体社会经济地位对上述中介效应的调节, 结果发现上述中介效应只出现在社会经济地位相对较高(vs.较低)的个体身上。     

睾酮素与反社会倾向未成年犯的攻击行为：敌意注意偏向的中介和皮质醇的调节作用

为考察睾酮素与反社会倾向未成年犯攻击行为的关系,在整合攻击行为生物激素视角和社会认知视角的基础上,探究敌意注意偏向的中介作用与皮质醇的调节作用。对84名未成年犯的激素水平、敌意注意偏向以及攻击行为进行调查。结果显示：(1)敌意注意偏向(注意不稳定性、注意回避)在睾酮素对攻击行为的影响中起完全中介作用;(2)皮质醇调节睾酮素与敌意注意偏向的关系,仅在高皮质醇水平下,敌意注意偏向的中介效应显著。基于生物激素影响攻击行为的中介机制和调节机制,可尝试从增加对敌意刺激的注意回避和提高皮质醇水平两个方面对反社会倾向未成年犯的攻击暴力行为进行干预。
