青少年创造性发展及其脑机制研究进展

青少年时期是创造性发展的关键阶段,探明青少年创造性发展规律及其神经机制对于培养和激发个体的创新潜能具有重要意义。本文综述了青少年创造性发展及其脑机制的研究进展,分别对青少年创造性思维发展趋势、影响因素及其相应的脑机制展开综述,并在此基础上进行了展望。总体而言,青少年时期创造性思维发展呈现出两个波峰(11~13岁,15~16岁)的发展趋势;青少年创造性发展受外部原生家庭教养方式和学校教师激励以及内部情绪动机和自我管理能力的影响较大;前额叶对青少年创造性发展具有重要作用,这可能与该脑区涉及执行控制功能有关。针对青少年创造性发展的教育干预以及大脑可塑性可能成为该领域的研究热点;而大样本纵向跟踪多模态脑影像数据库的建立可为相关研究提供重要支持。     

The Family and Partisan Socialization in Red and Blue America

How do competing social influences shape individual partisanship over the course of the life cycle? People enter and exit a host of environments over the course of the lifespan, and these environments provide social pressures that can conflict or reinforce early socialized attitudes. Socialization could be an agent for either opinion change or opinion stability. Using the Youth‐Parent Socialization Study and constructing partisan environmental measures at the county level, I explore this question. The findings demonstrate that environments exert significant socializing influence over the lifespan, moderating the persistence of early forces. This helps us understand when early socialized pressures persist and when they do not. When environments throughout life provide reinforcing social pressures, parental influence endures over time. However, when early socialized influence is challenged over time by the political environment that citizens reside in, the influence of early parental socialization is offset and nullified.     

CAUSATION,DISPOSITIONS, AND PHYSICAL OCCASIONALISM

Even though theistic philosophers and scientists agree that God created, sustains, and providentially governs the physical universe and even though much has been published in general regarding divine action, what is needed is a fine‐grained, conceptually coherent account of divine action, causation, dispositions, and laws of nature consistent with divine aseity, satisfying the widely recognized adequacy conditions for any account of dispositions.¹ Such an account would be a basic part of a more comprehensive theory of divine action in relation to the fundamental concepts of science and of mathematics. Our aim in this article is simply to present such a theory.     

A mechanistic perspective on canonical neural computation

Although it has been argued that mechanistic explanation is compatible with abstraction (i.e., that there are abstract mechanistic models), there are still doubts about whether mechanism can account for the explanatory power of significant abstract models in computational neuroscience. Chirimuuta has recently claimed that models describing canonical neural computations (CNCs) must be evaluated using a non-mechanistic framework. I defend two claims regarding these models. First, I argue that their prevailing neurocognitive interpretation is mechanistic. Additionally, a criterion recently proposed by Levy and Bechtel to legitimize mechanistic abstract models, and also a criterion proposed by Chirimuuta herself aimed to distinguish between causal and non-causal explanation, can be employed to show why these models are explanatory only under this interpretation (as opposed to a purely mathematical or non-causal interpretation). Second, I argue that mechanism is able to account for the special epistemic achievement implied by CNC models. Canonical neural components contribute to an integrated understanding of different cognitive functions. They make it possible for us to explain these functions by describing different mechanisms constituted by common basic components arranged in different ways.     

不安全依恋者注意偏向的形成机制及神经基础

不安全依恋者的注意偏向是指依恋焦虑和回避个体对依恋信息产生或趋近或回避的注意偏好, 这一注意偏好使得个体形成了处理与依恋对象关系的特殊认知机制：依恋回避个体偏好采用防御性机制, 倾向于回避对依恋信息的注意; 依恋焦虑个体偏好采用夸大性机制, 倾向于夸大威胁性信息, 因而会积极寻求与依恋对象的亲近。不安全依恋者注意偏向的差异主要体现在情绪信息、痛觉感受和工作记忆三个方面; 加工阶段特征主要涉及P1、N1波等代表的注意自动加工和LPP波代表的注意控制加工; 脑网络上主要包括两个子网络, 即负责情绪评估的边缘系统和负责情绪调节的以前额叶为代表的神经网络。未来研究中更应该关注刺激物的生态效度, 检验依恋系统是否激活, 不安全依恋者注意偏向的自动加工和控制加工阶段的关系, 不安全依恋者注意偏向产生的分子遗传机制以及注意偏向的跨文化研究。     

Measuring social influence of a senior midwife on decision‐making in maternity care: an experimental study

The document Changing Childbirth produced by the Department of Health (1993) requests provision of more choice, continuity and control for women during pregnancy and childbirth. In this context this study considers whether midwives'decisions are influenced by a senior midwife. A simple, valid and reliable scale—the Social Influence Scale for Midwifery (SIS‐M)—was devised to measure and score midwives' private anonymous responses to 10 clinical decisions. The SIS‐M was initially administered as a self‐completed postal survey by 209 midwives. Following a 9‐month time gap, a stratified sample of 60 (20 E, F, G grade midwives) were invited for interview in which a senior midwife attempted to influence SIS‐M responses in a conformist direction. Overall, a 3 × 2 (E, F, G grade midwives x private and interview SIS‐M scores) analysis of variance (ANOVA) revealed midwives were significantly more conformist when influenced by a senior midwife, in comparison to private anonymous responses. No significant interaction between groups was found. These findings indicate that there is influence of a senior midwife on clinical decisions that should be woman‐centred, according to Changing Childbirth (1993). The implication is that this influence may remove choice from women. Copyright © 2005 John Wiley & Sons, Ltd.

分散注意条件下前瞻记忆的完成水平及其影响因素初探

本研究试图探讨在分散注意条件下前瞻记忆的完成水平及其影响因素。被试为98名大学生。在实验中,当前任务为数字听写,同时放映一段无声动画短片,将前瞻记忆任务(即看到某一靶线索画面时在相应数字上做记号)嵌入其中,动画片结束后要求被试完成若干与动画片内容有关的问题(事先通过指导语告知)。结果发现：1、前瞻记忆任务的成绩与被试的性别几乎无关,与材料熟悉程度也无显著相关;2、与被试对材料的喜好程度显著相关,提示即使在分散注意条件下,被试在完成前瞻记忆任务时也可能会根据偏好自动调整注意的分配。
