儿童空间再定向能力发展的理论之争

空间再定向是指迷失方向的个体在空间中重新确定自己方位并找回迷失方向前丢失或被隐藏物体的能力.几何模块理论、适应性结合理论和视觉图像匹配理论都能够对儿童空间再定向做出一定解释,但三者之间互不相容,并存在局限:解释不了语言对整合几何和非几何信息的影响、环境空间大小和参照系选择对再定向的影响以及空间再定向中性别差异的现象.今后研究应注意实验的生态效应、空间条件的规则性、几何信息的直接性与间接性以及对三个理论的整合.     

From Standardization to Adaptation: Clinical Trials and the Moral Economy of Anticipation

Hailed as the gold standard, the randomized controlled trial (RCT) occupies a hegemonic position at the top of evidence-based medicine’s hierarchy of knowledge. It is testament to the methodology’s capacity for standardization that it can so readily be spoken of in the singular: the RCT. Under what conditions, then, is it possible to speak of change in the gold standard? Since the 1950s, alternative versions of the RCT have been advocated for under the banner of ‘adaptive design’. Adaptive designs allow investigators to make pre-planned changes to a trial on the basis of accruing information while the experiment is ongoing. Initially a niche topic of methodological debate among biostatisticians, the approach is becoming widespread in mainstream drug development. A genealogical analysis exposes the discursive moves used to justify and popularize adaptation, from a focus on patient well-being and the greater good in the 1960s and 1970s, to efficiency and virtualism in the 1990s and 2000s. Changing discourses of time and patienthood have facilitated a move away from standardization as the singular logic of trials towards an appreciation of flexibility, undergirded by probabilistic methodologies. Adams et al.’s [(2009). Anticipation: Technoscience, life, affect, temporality, Subjectivity, 28, pp. 246–265] conceptual framework of anticipation illuminates this evolving moral economy of medical research, in which modes of knowledge production which claim to know the future are supplanting the traditional certainties of fixed and standardized experimental designs. Predictable uncertainty is the currency of this emerging economy, which capitalizes on computer simulation and ever more sophisticated tools of prediction to leverage credibility.     

The Function of Moods and Emotions: Comment on “Can Sadness Be Good for You? On the Cognitive,Motivational and Interpersonal Benefits of Mild Negative Affect” (Forgas, 2017)

Evolutionary theories suggest that all affective states have a function. The fascinating review “Can Sadness Be Good for You? On the Cognitive, Motivational and Interpersonal Benefits of Mild Negative Affect” by Joseph Forgas is a welcome reminder that happiness is not the be all and end all—sadness can also be beneficial. In this commentary, I summarise the studies conducted by Forgas et al. that demonstrate the benefit of mild negative affect for memory, judgement, motivation, and interpersonal behaviour (and those that do not), link them to current theories and models, and discuss avenues for future research.     

允许CAT题目检查的区块题目袋方法

允许题目检查能够促进计算机化自适应测验(CAT)在实际中的应用。在不影响能力估计精度和测验公平性的前提下, 允许CAT题目检查能够缓解考生考试焦虑, 减少无关因素引起的测量误差。区块题目袋方法是连续区块方法与题目袋方法的结合, 不仅能允许CAT题目检查, 还能够弥补题目袋方法的不足。研究结果表明：(1)合理作答策略下, 区块题目袋方法的估计精度在低能力水平上要优于题目袋方法; (2)在应对类似Wainer作答策略时, 区块题目袋方法的估计精度在所有能力水平上均优于题目袋方法。(3)随着区块数的增加, 区块题目袋方法的能力估计精度越接近无修改的基线水平。     

厌恶的起源及其泛化:进化的观点

厌恶是人类的基本情绪之一,也是情绪心理学的研究重点。以进化论为指导的进化心理学对厌恶研究提供了一个崭新的理论视角,认为人类厌恶情绪源于抵御寄生物和保持种群规模的需要。现代人类的多种复杂的道德厌恶感与生理厌恶感有着同样的进化根源,人类的道德心理系统有部分是建立在更为古老的进化适应基础之上。     

适应性绩效：一个尚需深入研究的领域

适应性绩效是指应对工作要求和环境变化的各类行为。相关实证研究表明, 适应性绩效与任务绩效和周边绩效可能存在内容上的重叠, 有关适应性绩效的具体结构维度还存在争议。一般认知能力、知识技能、大五人格、自我效能、组织内的人际支持和环境支持, 以及组织外社会关系网络等因素对适应性绩效具有预测作用。未来的研究可以从适应性绩效的理论建构、测量工具、影响因素和实践应用等方面进行深入探讨。     

HOW CAN SCIENCE HELP RELIGION TOWARD OPTIMAL BENEFIT FOR SOCIETY?

Abstract. The dispute between theism and atheism has centered on whether there exists any entity that may be referred to as God and on how to explain life and the universe. As a consequence of this dispute and of the power of scientific explanations, religion may end up having less impact on society. The situation makes the following questions relevant: What are the advantages and disadvantages for society of downgrading religion? If the net effect of religion is considered to be positive, is it possible to counteract this trend? Moreover, examining the benefits of religion raises a further question: Is it possible to influence theology toward a stance with optimal utility for society? As a scientist writing from an atheist perspective, I argue that religion has a potential for serving society and that this advantage need not necessarily be sacrificed on the altar of science.     

Bayesian adaptive estimation: The next dimension

We propose a new psychometric model for two-dimensional stimuli, such as color differences, based on parameterizing the threshold of a one-dimensional psychometric function as an ellipse. The Ψ Bayesian adaptive estimation method applied to this model yields trials that vary in multiple stimulus dimensions simultaneously. Simulations indicate that this new procedure can be much more efficient than the more conventional procedure of estimating the psychometric function on one-dimensional lines independently, requiring only one-fourth or less the number of trials for equivalent performance in typical situations. In a real psychophysical experiment with a yes-no task, as few as 22 trials per estimated threshold ellipse were enough to consistently demonstrate certain color appearance phenomena. We discuss the practical implications of the multidimensional adaptation. In order to make the application of the model practical, we present two significantly faster algorithms for running the Ψ method: a discretized algorithm utilizing the Fast Fourier Transform for better scaling with the sampling rates and a Monte Carlo particle filter algorithm that should be able to scale into even more dimensions.     

上海市中学生心理健康自评量表的研究

本研究以中学生心理健康八条标准为理论构架,编制《上海市中学生心理健康自评量表(SISMSS)》。该量表共140个项目,由三个分量表组成,即适应性诊断量表、疾病性诊断量表和测谎量表,适应性诊断量表包含8个小测验,即主动学习、情绪乐观与稳定、自制力、自我认知、成就动机、与人沟通、责任感、性意识;疾病性诊断量表包含7个小测验,即精神分裂症倾向、抑郁症倾向、轻躁狂倾向、强迫症倾向、焦虑症倾向、恐怖症倾向、歇斯底里症倾向。适应性诊断量表与疾病性诊断量表之间并不是相互独立的,而是存在着一定程度的相关,有对应关系。SISMSS的内在一致性系数为0.9081(p<0.01),SISMSS与SCL-90之间的相关为0.589(p<0.01),SISMSS与MHT之间的相关为0.734(p<0.01)。
