时-空整合影响图形识别的眼动研究

采用眼动追踪的方法对在不同方向(上、下、左与右)及距离(2.0°‘和4.0°视角)上先后出现的特征组合不同的图形识别过程进行了研究。结果表明。首先,对由不同颜色和形状构成的图形的识别受到图形特征组合的影响,视觉系统对颜色和形状的加工存在明显差异,与颜色加工相比,视觉系统需要更多的时间才能完成形状识别。此外,虽然图形识别的速度和准确性受运动方向与距离的影响较小,但在不同运动方向和距离上,视觉系统是通过改变眼动的时间和空间特性来完成识别任务的,视觉系统在识别过程中的这种时间与空间的整合特点还有待于进一步研究。     

内隐学习研究方法述评

内隐学习自提出以来就成为认知心理学研究的热点,近40年内隐学习领域的研究在本质上都基于几种经典的研究方法和实验逻辑。本文拟对这些代表性的内隐学习研究方法做系统的介绍和归纳。     

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。     

“道”性、“水”性、人性、中国人人格

＂道＂性-＂水＂性-人性-中国人人格具有内在一致性,形成了一个一以贯之的有机体系。在这一有机体系中,作为＂道＂性的＂代言人＂,＂水＂性成为＂道＂性与人性及中国人人格间的＂中介者＂。以＂几于道＂的＂水＂为中介,通过对道家思想的分析,反观得到了道家思想影响下中国人的人性建构及人格特征,具体表现为：在思维上明＂道＂并懂得＂道＂的运行规律,以联系、变化和矛盾的眼光看待万事万物,情绪情感上静而不躁,意志品质上柔韧而不强作妄为,行事处世上既超脱一已之私、于物寡欲,又能待人谦退不争,并能从整体上显现出＂道＂之＂自然本真＂的根本特性。文末探讨了道家思想文化影响下,所形成的中国人独特的人格特征与现代化建设事业可能的适应情形。     

父母教养与学业成就：心理因素的中介作用

近十几年来,研究者们致力于探究父母教养与子女学业成就关系的内在机制。认知、大五人格、动机与自我概念作为学习者的心理特质,在父母教养与学业成就间起着重要的中介作用。父母教养能通过影响这些心理因素间接地影响子女的学业成就。尽管研究者们在该领域已经取得较为丰富的研究成果,仍需要在将来加强综合性研究、应用研究和跨文化比较研究,以深化和拓展对这一领域的探索,同时促进已有研究成果的应用。     

一个带有事务管理的动态偏好逻辑

问题对偏好的变化会有影响。本文在偏好逻辑的背景下考虑事务管理并提出了一个新的带有事务管理的动态偏好逻辑。我们的逻辑表明它能把其他情况均同的偏好（ceteris paribus preference）与普通的偏好联系起来并将其动态化和显性化。并且,通过引入混合逻辑使得我们能在同一层次谈论命题和对象之间的偏好,除提问这个行动之外,我们还在逻辑系统的动态部分考虑了解决、建议和软公开宣告等行动。在对这四种行动的不同影响进行比较后,我们证明了这个动态系统的完全性。

Sample size planning with the cost constraint for testing superiority and equivalence of two independent groups

The allocation of sufficient participants into different experimental groups for various research purposes under given constraints is an important practical problem faced by researchers. We address the problem of sample size determination between two independent groups for unequal and/or unknown variances when both the power and the differential cost are taken into consideration. We apply the well‐known Welch approximate test to derive various sample size allocation ratios by minimizing the total cost or, equivalently, maximizing the statistical power. Two types of hypotheses including superiority/non‐inferiority and equivalence of two means are each considered in the process of sample size planning. A simulation study is carried out and the proposed method is validated in terms of Type I error rate and statistical power. As a result, the simulation study reveals that the proposed sample size formulas are very satisfactory under various variances and sample size allocation ratios. Finally, a flowchart, tables, and figures of several sample size allocations are presented for practical reference.     

New heterogeneous test statistics for the unbalanced fixed‐effect nested design

When the underlying variances are unknown or/and unequal, using the conventional F test is problematic in the two‐factor hierarchical data structure. Prompted by the approximate test statistics (Welch and Alexander–Govern methods), the authors develop four new heterogeneous test statistics to test factor A and factor B nested within A for the unbalanced fixed‐effect two‐stage nested design under variance heterogeneity. The actual significance levels and statistical power of the test statistics were compared in a simulation study. The results show that the proposed procedures maintain better Type I error rate control and have greater statistical power than those obtained by the conventional F test in various conditions. Therefore, the proposed test statistics are recommended in terms of robustness and easy implementation.     

自然主义集合实在论与数学哲学研究范式

In recent 50 years,the debate between mathematical realism and anti-realism has been dominating the mainstream development in the contemporary philosophy of mathematics. Penelope Maddy proposed a naturalistic set theoretic realism in 1990. This project brings the philosophy of mathematics a new research idea,that is,philosophy should attach importance to mathematical practice. This article will critically analyze Maddy's naturalistic set theoretic realism on the basis of research paradigm background belief....
