技术理性的伦理表征及其超越

技术理性作为一种观念和能力,通过其伦理表征引导人类的行为。技术理性主要表现为追求最大化力量和力量最大化的力量伦理、追求产出最大化和投入最小化的效率伦理、追求规则与目标一致性的计算伦理、追求永无止境增长的增长伦理,在给人类社会带来繁荣的同时也招致诸多负面影响和伦理风险。为了克服技术理性的负面影响,人类需要构建包括非力量伦理、责任伦理和发展伦理在内的新伦理。     

幼儿害羞与社会适应:母亲教养方式的调节作用

本研究以487名幼儿为被试,探讨害羞与社会适应的关系,以及母亲教养方式在害羞与社会适应之间的调节作用。幼儿母亲完成儿童社会偏好量表和教养方式问卷,幼儿教师完成对幼儿社会适应的评价。结果表明:(1)害羞与不合群和同伴排斥显著正相关;(2)母亲教养方式在害羞与社会适应之间具有调节作用。具体来说,母亲温暖、说理和鼓励自主的教养方式可减弱害羞幼儿的消极适应,而体罚和指令型的教养方式会加剧害羞幼儿的消极适应。研究结果对于害羞幼儿的干预具有重要价值。

螺旋CT双期增强薄层扫描对小胰腺癌诊断的研究

为了研究螺旋CT胰腺期、肝脏期双期增强薄层扫描在小胰腺癌早期诊断中的作用,对25例小胰腺癌患者行螺旋CT双期增强扫描,结果显示,两组观察结果经统计学处理有显著性差异,螺旋CT动态增强薄层2mm扫描比5mm扫描可明显提高小胰腺癌和微胰腺癌的检出率,对小胰腺癌的早期诊断有重要的临床价值.肝脏期扫描为临床确定肿瘤是否能够手术切除提供科学依据.     

What Matters Most to the Left-Behind Children’s Life Satisfaction and School Engagement: Parent or Grandparent?

This study compared the role of the parent and grandparent in the adjustment of children who had, and who had not, been left behind when their parents moved to urban areas for work, and tested whether self-esteem mediated the association between these family relationships and child adjustment. The sample included 428 middle school students in central China, 204 of whom were left-behind children who were cared for by grandparents and 224 of whom were not left behind. The students responded to five questionnaires measuring parent–child relationships, grandparent–child relationships, self-esteem, life satisfaction and school engagement. Regression analyses showed that self-esteem mediated the association between parent–child and grandparent–child relationships and children’s adjustment, but there were different patterns of association for the non-left-behind children and left-behind children groups. Furthermore, the unique effect of parent–child relationships was higher than that of grandparent–child relationships for the non-left-behind children, but for the left-behind children, grandparent–child relationships played a more important role than grandparent–child relationships in predicting their school engagement, and parent–child relationships played a more important role in predicting their life satisfaction. Parents who are far away and grandparents who are close at hand can shape different psychological and behavioral development outcomes of left-behind children.     

Vocabulary growth rate from preschool to school‐age years is reflected in the connectivity of the arcuate fasciculus in 14‐year‐old children

The acquisition of language involves the functional specialization of several cortical regions. Connectivity between these brain regions may also change with the development of language. Various studies have demonstrated that the arcuate fasciculus was essential for language function. Vocabulary learning is one of the most important skills in language acquisition. In the present longitudinal study, we explored the influence of vocabulary development on the anatomical properties of the arcuate fasciculus. Seventy‐nine Chinese children participated in this study. Between age 4 and age 10, they were administered the same vocabulary task repeatedly. Following a previous study, children's vocabulary developmental trajectories were clustered into three subgroups (consistently good, catch‐up, consistently poor). At age 14, diffusion tensor imaging data were collected. Using ROI‐based tractography, the anterior, posterior and direct segments of the bilateral arcuate fasciculus were delineated in each child's native space. Group comparisons showed a significantly reduced fractional anisotropy in the left arcuate fasciculus of children in the consistently poor group, in particular in the posterior and direct segments of the arcuate fasciculus. No group differences were observed in the right hemisphere, nor in the left anterior segment. Further regression analyses showed that the rate of vocabulary development, rather than the initial vocabulary size, was a specific predictor of the left arcuate fasciculus connectivity.

方言经验对早期沪语儿童汉语语音意识的影响

已有研究对汉语儿童的英语语音意识进行研究,且取得了很多有价值的研究成果,但对方言儿童的汉语语音意识的研究很少。汉语是一种具有众多方言的独特语言,许多方言和标准语的语言体系有着显著差异。具有方言和普通话早期经验的双语儿童在汉语语音意识上是否存在优势,有两种不同的看法：一是从心理语言学层面上,母语学习中获得的语言能力或普遍语法能促进第二语言的学习;二是从语言学层面上来讲,母语对第二语言的学习存在干扰作用。那么双语儿童在汉语语音意识上比单一普通话儿童是否存在优势呢？本研究将进行调查。实验选取72名4岁、5岁和6岁学前儿童为被试,每个年龄组各24人,其中沪语儿童和单一普通话儿童各12名。采用听觉呈现方法对所选被试进行汉语语音意识水平的测试,包括声调意识、声母意识和韵母意识三部分,并收集儿童的口语资料。结果表明: 虽然沪语儿童声母意识和韵母意识主效应不显著,但沪语儿童语音意识总成绩和声调意识成绩均比单一普通话儿童高;沪语儿童汉语语音意识优势不受年龄的影响。本研究启示是,上海地区学前儿童学习标准语（普通话）之外应鼓励使用沪语。     

Attentional spreading in object-based attention: The roles of target–object integration and target presentation time

What is the best account to explain the object-based attentional benefit—that is, the spread of attention within an attended object or prioritization of search across possible target locations within an attended object? Using a task in which the location of the target was known with certainty, in the present study we systematically manipulated the type (letters or bites) and the presentation time (long or short) of the target and flankers in order to test the effects of target–object integration and target presentation time on object-based attention. The results showed that an object-based effect could appear when the target was a bite, no matter whether the target presentation time was long or short; but when the target was a letter, an object-based effect was only observed when the target presentation time was short enough. These findings provide additional evidence supporting the argument of attentional spreading in object-based attention. However, this spreading is moderated jointly by target–object integration and the target presentation time.
