汉语隐喻理解时程的ERPs研究

摘 要 本研究使用ERPs技术考察隐喻句与本义句理解时程的异同,以研究汉语隐喻的理解机制。以句尾范式向被试随机呈现本义句、熟悉隐喻句、新奇隐喻句及错误义句各50句,被试的任务为判断每句话是否有意义。结果显示：两种隐喻句诱发的N400波形与头皮分布情况和本义句无明显差异,且两种隐喻句诱发的N400波幅高于本义句。本研究结果证明汉语隐喻义和本义理解的认知机制类似,支持隐喻理解的平行加工假说,且加工隐喻义需要耗费更多的认知资源。     

人际关系互动中人际特质的环形模型探索

人际环是以水平轴亲和维度和垂直轴控制维度为核心,按照规定序列排列在一个环形的空间。研究目的:研究融合人际互动与人格特质两个心理学研究领域,探讨中国文化下人际互动中人际环状结构。研究方法:本研究以人际环为理论基础,设计三种不同关系类型:夫妻关系、同性好友关系和恋人关系,采用多元变量分析和随机化测验方法检验本土文化下人际互动中个体的人际特质结构。研究结果:显示互动中个体人际特质以两个基本维度(亲和维和控制维)为核心,这两个维度体现出人际关系互动中的两个重要信息:地位和爱。人际特质包含六个因子,分别是人际冷漠性、人际亲和性、人际开放性、人际退缩性、社会支配性和社会服从性。此六因子以水平轴亲和维度和垂直轴控制维度为核心,形成一个不规则的六边环形,并以规定序列排列成环形空间。     

Radical Scepticism,How-Possible Questions and Modest Transcendental Arguments

According to radical scepticism, knowledge of the external world is impossible. Transcendental arguments are supposed to be anti-sceptical, but can they provide a satisfying response to radical scepticism? Especially, when radical scepticism is cast as posing a how-possible question, there is a concern that transcendental arguments are neither sufficient nor necessary for answering such question. In light of this worry, I argue that we can take a modest transcendental argument as a stepping stone for a diagnostic anti-sceptical proposal, and I use a Wittgensteinian modest transcendental argument to illustrate my point.

刻板印象内容模型：理论假设及研究

介绍了刻板印象内容模型(SCM)的来源、理论假设和在美国与欧洲(个人主义文化)、东亚(集体主义文化)样本中的实证研究。SCM假设:(1)用热情和能力区分不同群体的刻板印象;(2)对外群体的刻板印象是混合的;(3)高社会地位群体被刻板为具有高能力,竞争性群体被刻板为缺乏热情;(4)刻板印象中存在参照群体偏好和外群体贬抑。在比较和评价SCM与其他理论的基础上,提出了刻板印象内容研究进一步细化和扩展的方向     

城市人口健康的性别差异及影响因素的实证分析

使用CHNS数据,在健康的社会分层模式下探讨城市人口健康的性别公平问题。研究认为,中国城市人口健康存在显著的性别不平等现象,男性健康水平要好于女性,而这种健康的性别差异主要是由于不同性别在社会经济地位上的差异造成的,女性处于明显的弱势地位。     

Maternal perceptions of the sleep patterns of premature infants at seven months corrected age compared to full-term infants

It has been reported that 83%–87% of full-term infants regularly sleep through the night (from midnight to 5 a.m.) by 6 months of age, but there is little information about the sleep patterns of premature infants. The purpose of the current study was to identify maternal perceptions of the sleep patterns of premature infants. Parents of 32 premature infants with birth weight below 1,750 gm and of 13 full-term infants completed a 24-hour sleep record in 30-minute epochs for 1 week at 7 months of chronological (term) or corrected age (premature). Mean birth weight of premature infants was 1,278 ± 340 gm, with a gestational age of 30.4 ± 2.7 weeks. The daily total sleep time, longest sleep segment, frequency of sleep-wake transitions, and percentage of night sleep (8 p.m.–8 a.m.), averaged from the 1-week sleep record and number of night wakenings per week, were used as indicators of sleep patterns. The longest reported sleep segments of premature infants were significantly shorter than those of full-term infants (8.2 ± 2 hours versus 9.6 ± 1 hour, p < 0.01) and the number of night wakenings per week was significantly greater (3.13 ± 3 versus 0.54 ± 7, p < 0.005). Total reported sleep time, percentage of night sleep, and sleep-wake transitions did not differ significantly between premature and full-term infants. However, analysis of feeding events revealed that premature infants received significantly more feedings between midnight and 5 a.m. (M = 0.31 + 3 versus M = 0.06 + 1, p < 0.001). We conclude that sleep pattern diaries kept by parents indicate that premature infants have developed a diurnal sleep rhythm by 7 months corrected age, but they still have shorter sleep segments and they awaken more during the night than term infants.     

有病切勿求神拜佛乱投医

A daily diary study of the relationships among daily self-compassion,perceived stress and health-promoting behaviours

Previous studies consistently found that trait self-compassion is positively associated with health-promoting behaviours, and perceived stress mediates the relationship. The current study primarily aimed at examining whether state self-compassion varying from day to day (daily self-compassion) played the same role as trait self-compassion in improving health-promoting behaviours and whether or not perceived stress would be the mediator in this relationship. Eighty-nine Chinese employees were recruited to finish demographic information and the trait measure of self-compassion first, and then finish daily diaries for seven consecutive days. Daily diary measures included daily self-compassion, perceived stress and health-promoting behaviours including both eating behaviours and exercise behaviours. The results of 1-1-1 multilevel mediation analyses showed that, at both the within- and between-person level, daily self-compassion could positively predict daily eating behaviour through the reduction of perceived stress. However, daily self-compassion did not influence exercise behaviour at both levels. The results of 2-1-1 multilevel mediation analyses cross-validated the between-person relationships in the 1-1-1 multilevel mediation models. These results suggest that, both short-term interventions aiming at increasing state self-compassion and long-term interventions aiming at increasing trait self-compassion can benefit one's eating behaviours through the reduction of stress.     

Epigenetic regulation of reelin and brain-derived neurotrophic factor genes in long-term potentiation in rat medial prefrontal cortex

Epigenetic mechanisms have recently been known to play fundamental roles in the regulation of synaptic plasticity, and learning and memory tasks in many brain regions, such as the hippocampus, the amygdala, the insular cortex. However, epigenetic mechanism in the medial prefrontal cortex (mPFC), also a crucial neural locus for the control of cognition and emotion, is not well known. The present study investigated the epigenetic regulation of two genes, reelin and brain-derived neurotrophic factor (bdnf), both play important roles in neural plasticity, in the mPFC. The data showed that the levels of total DNA methyltransferase (DNMTs), total histone acetyltransferases (HATs), global acetylated histone 3 (H3) and global acetylated histone 4 (H4) were all changed with the induction of long-term potentiation (LTP) in the mPFC, implying that DNA methylation and histone acetylation may involve in synaptic plasticity in the mPFC. The present results further demonstrated that the demethylation status of reelin and bdnf, and acetylated H3 and acetylated H4 at the reelin and the bdnf promoters in the mPFC were enhanced by the delivery of LTP-inducing high-frequency stimulation (HFS). Consistently, infusion of DNMT inhibitor, 5-azacytidine (5-azaC), or histone deacetylases (HDACs) inhibitor, sodium butyrate (NaB), into the mPFC could interfere with LTP-associated demethylation and acetylation of reelin and bdnf genes, and the induction of LTP as well. Long-term retention of trace fear memory, which is dependent on mPFC function, was also altered by administration of these inhibitors into the mPFC. These findings suggest that epigenetic regulation of DNA demethylation and histone acetylation of target genes, such as reelin and bdnf, might underlie the mechanisms of synaptic plasticity and memory retention in the mPFC.
