斯-欧非言语智力测验评介

斯-欧非言语智力测验1943年由荷兰女学者Snijders-Oomen编制,经多次修订后出现多个版本,目前应用最广、最新和最具代表性的是SON-R 5.5-17和SON-R 6-40两个版本。前者包含归类、拼板、隐蔽图形、连线、情境、类比和故事七个分测验,考查5.5岁到17岁人群的抽象推理、具体推理、空间、知觉四种能力。后者选取了类比、拼板、归类和连线四个分测验组成,测查6岁到40岁人群的智力。研究表明,该测验内部一致性信度、概化系数和效度均达到了心理测量学质量要求。该测验有言语指导和非言语指导两套指导语,施测使用了适应性程序,并给被试提供反馈,具有认知诊断功能,适用于测量正常和特殊群体的智力,也可用于研究文化因素对智力的影响和智力测验的公平性等问题。     

Socioeconomic status and school grades: Placing their association in broader context in a sample of biological and adoptive families

SES has long interested researchers investigating school achievement. Its effects are often addressed by studying predictors of achievement in economically disadvantaged samples living primarily in biological families, confounding genetic and environmental influences. Little is known about SES's purely environmental effects. We measured them in 617 adoptive and biological families, adjusting for sample restriction of SES range. Controlling for gender, parenting, parental expectations for educational attainment (PEEA), IQ, engagement in school, and genetic and shared environmental influences on sibling pairs, SES still made a small but significant nonshared environmental contribution to school grades. IQ, PEEA, and SES had collinear associations with school grades, as did engagement and parenting. The associations of IQ and engagement with school grades were largely independent of each other. The link between PEEA and IQ was stronger in adoptive than biological offspring. We discuss the implications of these findings.     

Development of chromatic induction in infancy

The perception of colour in an embedded field is affected by the surround colour. This phenomenon is known as chromatic induction. In the present study we investigated whether the colour perception by infants aged 5–7 months could be affected by the surround colour. In Experiments 1 and 2 each stimulus was composed of an array of six squares in tandem. The colour appearance of the array in the familiarization stimulus was established by chromatic induction. In Experiment 1 we used familiarization stimuli that were perceived as two‐colour array with a two‐colour surround. In Experiment 2 we used a familiarization stimulus that was perceived as a uniform‐colour array with a two‐colour surround. In the test phase, the uniform‐colour array and the two‐colour array were presented on a white uniform‐colour surround in both experiments. The results showed that in Experiment 1 the 5‐ and 7‐month‐old infants had novelty preference for the uniform‐colour test array. This suggested that the infants' colour perception could be affected by surround colour. The results of Experiment 2 showed that the 7‐month‐olds showed a novelty preference for the two‐colour test array, but the 5‐month‐olds showed no novelty preference. This suggested that 7‐month‐olds' colour perception could be affected by surround colour, but that of 5‐month‐olds could not. We discuss the contradiction of the results between Experiments 1 and 2.

2岁幼儿的社会朝向反应——本质及功能

本研究以66对17至32个月的幼儿和母亲为研究对象,研究了在实验室情境中,幼儿在不同实验情境下对母亲的社会朝向反应,并探讨了幼儿社会朝向行为的功能以及母亲的行为对幼儿社会朝向反应的影响。结果显示,（1）大多数幼儿在实验中都表现出了至少一次的社会朝向反应,社会朝向反应的发生是酱遍的;（2）在不同情境中,幼儿的社会朝向反应不同,在积极的情境中,社会朝向反应有分享情绪经历的功能;在抗拒诱惑的任务中,社会朝向行为与获得支持有关;（3）母亲对情境的非信息性反应对幼儿的社会朝向行为有影响,社会朝向是幼儿对社会情境的适应性行为,对这种非语言的情感交流行为的研究可以帮助我们探究幼儿情绪社会化的过程。     

A Question of Balance or Blind Faith?: Scientists’ and Science Policymakers’ Representations of the Benefits and Risks of Nanotechnologies

In recent years, in the UK and elsewhere, scientists and science policymakers have grappled with the question of how to reap the benefits of nanotechnologies while minimising the risks. Having recognised the importance of public support for future innovations, they have placed increasing emphasis on ‘engaging’ ‘the public’ during the early phase of technology development. Meaningful engagement suggests some common ground between experts and lay publics in relation to the definition of nanotechnologies and of their benefits and risks. However, views on nanotechnologies are likely to vary according to where actors stand in the technology production/consumption/assessment cycle. Drawing on data from a recent UK-based study, this article examines how scientists (‘upstream’ and ‘downstream’) and policymakers portray the benefits and risks of nanotechnologies, particularly as they relate to two major areas of predicted application, namely medicine/public health and environmental sustainability. The findings reveal that, in the main, scientists and science policymakers held a positive conception of nanotechnologies and see imminent applications, although they acknowledged particular risks, including adverse public reaction. While definitions of ‘benefit’ and ‘risk’ varied, most saw the benefits as outweighing the risks and believed that the risks could be adequately regulated once they were assessed. The difficulties of assessing risk, however, were acknowledged. The study raises a number of questions that will need to be addressed if regulations are to be developed that not only protect people’s heath and wellbeing and the environment but also engender public trust in nanotechnologies.

Parent–infant co‐sleeping: fathers' roles and perspectives

Dyadic co‐sleeping (mother–baby) is a common strategy for night‐time infant care in the majority of world cultures. Triadic co‐sleeping (mother–father–baby) is less common, although still widely practised cross‐culturally. This paper examines triadic co‐sleeping in an opportunistic sample of parents from the North Tees region of England, and explores fathers' expectations and experiences of sleeping with their babies. Using a prospective study design, 36 sets of parents, pre‐ and post‐natally, were interviewed about infant care strategies, particularly at night. Although they did not anticipate sleeping with their infants at the pre‐natal interview, the majority of fathers (81%) had done so by the time of the second interview. First‐time fathers were afraid that they would squash or suffocate the baby in their sleep, and some were concerned that the infant's presence would adversely affect their own sleep. Fathers used a variety of strategies to help overcome their initial fears of co‐sleeping. Among those for whom triadic co‐sleeping became a regular night‐time infant care strategy, the pleasures of prolonged intimate contact with their infant were clearly apparent. It is suggested that the experience of sleeping with their infant ameliorates some of the distancing effects felt by fathers outside the breast‐feeding relationship, and helps encourage paternal involvement in night‐time infant care‐giving.

在线学习环境中教师幽默对学习投入的影响：一个多水平的结构方程分析

以教学幽默风格模型（Instructional Humor Styles）和教学幽默加工理论（Instructional Humor Processing Theory）为基础,通过构建多水平的结构方程模型探索在线学习环境中,教师幽默与学习投入关系。结果表明：（1）教师幽默与学习投入无显著相关;（2）在学生层面,仅学生感知的与课堂相关的教师幽默与学习投入呈显著正相关;（3）学生感知的与课堂相关,与课堂无关和攻击性的教师幽默均能通过积极情绪和消极情绪对学习投入产生影响。此外,自我贬低的教师幽默仅通过消极情绪对学习投入产生作用。本研究首次将教学幽默风格理论模型拓展至在线学习环境中,从教师层面和学生层面验证了该理论在我国的适应性。此外,本研究验证了教学幽默加工理论,揭示了教师幽默对学习投入的内在机制,这对改善在线学习环境中学生的学习投入具有一定的指导意义。     

Newborns of mothers with depressive symptoms are less expressive

The facial expressions of 40 newborns of mothers with depressive symptoms (n = 20) and of nondepressive mothers (n = 20) were recorded during the Brazelton Neonatal Behavior Assessment Scale and during the modeling of happy, sad, and surprised faces. Infants of mothers with depressive symptoms demonstrated inferior performance on the orientation cluster of the Brazelton scale and showed fewer interest and more precry expressions during the Brazelton. During the facial expression modeling, they showed less orientation and fewer facial expressions in response to the modeled happy and surprise facial expressions.

影响员工工作投入的组织相关因素研究

以361名企事业员工为被试,采用问卷法和结构方程建模分析方法探讨了组织公平、角色压力、组织支持感和组织承诺对工作投入的影响及其途径。结果表明:角色压力、组织公平与组织支持感均对工作投入和组织承诺有较好的预测效力。经检验,组织公平和组织支持感对工作投入产生显著的间接影响,组织承诺则主要表现为直接影响;而角色压力对于工作投入既有直接影响,又存在间接影响。
