Abstract: To face the challenges of keeping healthy in increasing population sizes of both ageing and developing people in China, a fundamental request from the public health is the development of lifespan normative trajectories of brain and behavior. This paper introduces the Chinese Color Nest Project (CCNP 2013–2022), a large-scale tenyear program of modeling brain and behavioral trajectories for human lifespan (6–85 years old). We plan to gradually collect the behavioral and brain imaging data at ages across the lifespan on nationwide and depict the normal trajectory of Chinese brain development across the lifespan, based on the accelerated longitudinal design in the coming next 10 years starting at 2013. Various psychiatric disorders have been demonstrated highly relevant to abnormal events during the neurodevelopment regarding their onset ages of first episodes. Therefore, delineation of normative growth curves of brain and cognition in typically developing children is extremely useful for monitoring, early detecting and intervention of various neurodevelopmental disorders. In this paper, we detailed the developing part of CCNP, devCCNP. It tracked 192 healthy children and adolescents (6–18 years old) in Beibei district of Chongqing for the first 5 years of the full CCNP cohort (2013–2017). To demonstrate the feasibility of implementing the longterm follow-up of CCNP, we here comprehensively document devCCNP in terms of its experimental design, sample strategies, data acquisition and storage as well as some preliminary results and data sharing roadmap for future. Specifically, we first describe the accelerated longitudinal sampling design as well as its exact ratio of sample dropping off during the data collection. Second, we present several initial findings such as canonical growth curves of cortical surface areas of a set of well-established large-scale functional networks of the human brain. Finally, together with records generated by many psychological and behavioral tests, we will provide an individual growing-up report for each family participating the program, initiating the potential guidance on the individual academic and social development. The resources introduced in the current work can provide first-hand data for a series of coming Chinese brain development studies, such as Chinese Standard MRI Brain Templates, Normative Growth Curves of Chinese Brain and Cognition as well as Mapping of Language Areas in Chinese Developing Brain. These would not only offer normative references of the atypical brain and cognition development for Chinese population but also serve as a strong force on accelerating the pace of integrating Chinese brain development into the national brain program or Chinese Brain Project.

统计推断在科学研究中起到关键作用,然而当前科研中最常用的经典统计方法——零假设检验(Null hypothesis significance test, NHST)却因为难以正确理解而被滥用或误用。有研究者提出使用贝叶斯因子(Bayes factor)作为是一种替代和(或)补充的统计方法。贝叶斯因子是贝叶斯统计中用来进行模型比较和假设检验的重要方法,这一方法对于心理学及相关领域的大部分研究者来说仍然比较陌生。因此,本文介绍了贝叶斯因子的基本思路,并总结了贝叶斯因子与NHST相比的优势。在此基础上,以贝叶斯独立样本t检验为例,演示如何在开放的统计软件JASP中实现贝叶斯因子的计算,并解释了对贝叶斯因子结果的解读。最后,对贝叶斯因子的不足及其应用价值进行了讨论。

分类: 心理学 >> 社会心理学

目的 随着文化心理学和大数据分析技术的发展,绘制区域内不同国家或地区的文化地图、进而预测其行为价值观。 方法 利用社交媒体结合世界价值观(World Value Survey WVS)数据库建立个人主义对个性解放与社会信任的预测模型。 结果 “一带一路”沿线国家或地区在独立性、独特性这等个人主义文化指标上存在较大的变异。 局限 自主、选择、言论自由等个性解放价值观以及针对陌生人、外国人的普遍信任及则不能通过个人主义指标来预测。 结论 “一带一路”沿线国家或地区的文化是多样的,我们可以通过社交媒体计算的个人主义指标来快速预测相应国家或地区的价值观与社会信任指标。

神经成像偏见及其心理机制

分类: 心理学 >> 法制心理学

神经成像的结果是否能够作为科学证据被呈现在法庭之上是一个有争议的问题。先前的研究发现,神经成像结果的大脑图片可能会让人们过度地信任其所支持的结论,这种过度信任被称为神经成像偏见(neuroimage bias)。但是,后续的研究却要么未能重复出早期研究的结果,要么发现神经成像偏见仅在某些特定的条件下出现。对这些研究的分析表明,神经成像对人们态度和决策产生影响的心理机制并不在于大脑图像的生动性,而可能是受到神经成像结果的科学性以及其他中介变量的调节。未来的研究需要进一步考察神经成像偏见效应的可重复性及其跨文化的普适性。
