Infant state in relation to its environmental context

Two neonatal intensive care units (NICU) were observed every 15 minutes for at least 72 consecutive hours. Although infants on both NICUs were exposed to considerable amounts of stimulation, there were differences between the units for each environmental measure in the amount of stimulation and/or the pattern of circadian periodicity. The two NICUs also differed in the amount of time infants spent in various states and in the pattern of state periodicity. In general, the diurnal rhythms of the infant states were associated with the diurnal rhythms of different environmental events; furthermore, the patterns of association were not the same on the two NICUs. The results point to potential problems in depicting a “typical” NICU. More importantly, they suggest that the environmental of NICUs has a recognizable influence on aspects of their inhabitants' behavior and that the nature of influence is different from NICU to NICU. The effects are potentially significant for physical, social, and cognitive development.     

听障儿童外部情绪理解研究

通过自编的外部情绪理解问卷,考察了听障儿童表情识别、情绪情景识别和提示物理解等外部情绪理解三个成分的发展状况。结果表明:(1)听力障碍儿童在外部情绪整体理解、表情识别、情绪情景识别和提示物理解四方面的得分都显著低于普通儿童;(2)不同年级听力障碍儿童的外部情绪理解、表情识别、情绪情景识别和提示物理解四方面得分存在显著差异,不同性别听力障碍儿童外部情绪理解差异不显著;年级和性别的交互作用显著;(3)父母听力状况不同的听障儿童,其外部情绪理解水平差异显著。DD儿童的外部情绪整体理解、表情识别和情绪情景识别得分显著高于DH儿童。     

Prenatal discrimination of a male and a female voice uttering the same sentence

Using a habituation/dishabituation procedure, near-term foetuses (36-39 weeks gestational age) were tested in a low variability HR state, to examine whether they could discriminate between a male and a female voice repeatedly uttering the same short sentence. Prosody and loudness of the two voices were controlled. Once the foetal heart rate (HR) habituated to the first voice, the effect of a second voice was investigated in two experimental conditions: male/female voice and female/male voice. HR variations after the onset of the second voice were compared to those occurring in two control conditions in which the same voice was presented twice (male/female voice and female/female voice). Highly conservative statistical criteria taking each subject's pre-stimulus HR variability into account showed that most foetuses exposed to the voice change displayed decelerative cardiac changes, with no significant difference between the two conditions. These HR decelerations were found in the first seconds following the onset of the new voice, and reached their peak amplitude within 10 s in most subjects. These responses lasted more than 10 s for two-thirds of the experimental subjects. Mostly transient HR accelerations and only a few decelerative changes were recorded in the control subjects. Furthermore, mean amplitudes of these changes were significantly lower than the HR decelerations induced by the new voice in the experimental conditions, suggesting that the latter were not spontaneous HR modifications but rather cardiac responses to the voice change. It is argued that near-term foetuses may perceive a difference between voice characteristics of two speakers when they are highly contrasted for fundamental frequency and timbre.     

幼儿看图叙述中心理状态术语的使用与错误信念理解关系的短期跟踪研究

摘 要：为探明汉语儿童看图叙述中心理状态术语的应用及与错误信念理解能力的关系,并追踪二者相互作用的方向,本研究以101名3-5岁儿童为研究对象,纵向探查了前后相隔3个月的儿童看图叙述中心理状态术语使用情况和错误信念能力的发展状况,并从横向和纵向两个时间点分别探讨了心理状态术语的运用与错误信念理解的关系。结果表明：3-5岁儿童错误信念理解能力快速发展;儿童看图叙述中使用较多的愿望术语和情绪术语,信念术语应用相对较少,且认知词汇类型较少。控制了一般语言能力和年龄之后,仅在第一次测验上,情绪术语、信念术语仍然与同期及后期错误信念理解能力存在显著相关。     

不同亚型ADHD儿童的视通道时距估计能力

本研究选取ADHD混合型儿童11名,ADHD注意缺损型儿童13名以及正常儿童15名,通过\"平均估计长度\"、\"平均估计误差百分比\"、\"估计变异值\"三个指标,考察不同亚型ADHD儿童在时距复制和言语估计上的稳定性和精确性。研究发现,在视觉刺激条件下,ADHD儿童的时距估计缺损并不受时距长度的影响;ADHD混合型儿童在多项任务中所表现的稳定性和精确性都差,而ADHD缺损型儿童只是稳定性差,说明ADHD混合型是ADHD中更严重的亚类型;ADHD儿童在时距估计任务中稳定性差,反映了其状态调节能力的落后。     

复兴国家:国家理论的新形态

民族国家的架构尽管日益式微,但它在组织全球化经济、全球化政治和正在形成的全球公民社会中仍然占有首要地位。民族国家不是在消亡,而是正在被重新想象、重新设计、重新调整方向以回应一系列挑战。相应地,对国家的研究在现时代仍然具有重要意义,在全球化背景下,全球资本、全球公民社会、全球治理与民族国家的关系研究构成了国家理论的新形态。     

"儿童对主观世界认识的发展"研究的热点

“儿童对主观世界认识的发展”研究经历了三次浪潮,第一次是以Piaget为代表的“自我中心主义的学说”;第二次是20世纪70年代兴起的“元记忆“的研究;第三次是20世纪80年代初兴起的“心理理论”的研究。本文分析了当前就“儿童对主观世界认识的发展”两大研究热点：元记忆和心理理论的研究。文章对元记忆和心理理论这两次研究浪潮的历史渊源、发展现状、相互之问的关系进行了剖析,特别对其分离与统合的现状进行了介绍,并对将来的研究进行了展望。
