The ameliorating effect of oroxylin A on scopolamine-induced memory impairment in mice

Oroxylin A is a flavonoid and was originally isolated from the root of Scutellaria baicalensis Georgi., one of the most important medicinal herbs in traditional Chinese medicine. The aim of this study was to investigate the ameliorating effects of oroxylin A on memory impairment using the passive avoidance test, the Y-maze test, and the Morris water maze test in mice. Drug-induced amnesia was induced by administering scopolamine (1 mg/kg, i.p.) or diazepam (1 mg/kg, i.p.). Oroxylin A (5 mg/kg) significantly reversed cognitive impairments in mice by passive avoidance and the Y-maze testing (P<.05). Oroxylin A also improved escape latencies in training trials and increased swimming times and distances within the target zone of the Morris water maze (P<.05). Moreover, the ameliorating effects of oroxylin A were antagonized by both muscimol and diazepam (0.25 mg/kg, i.p., respectively), which are GABA(A) receptor agonists. Furthermore, oroxylin A (100 microM) was found to inhibit GABA-induced inward Cl(-) current in a single cortical neuron. These results suggest that oroxylin A may be useful for the treatment of cognitive impairments induced by cholinergic dysfunction via the GABAergic nervous system.     

错误记忆的产生是否依赖对词表的有意加工：无意识激活的证据

使用DRM范式考察了错误记忆产生过程中无意识激活的存在与否。通过操纵实验任务和呈现方式,导致被试对学习词表的无意加工和不同水平的有意加工。结果发现,无意加工时所产生的对关键诱饵的无意识激活足以导致错误记忆效应,说明对词表的有意加工并非错误记忆产生所必需。随着对词表有意加工水平的提高,多次无意识激活的累积可导致增强的错误记忆效应,且表现出与真实记忆的共变,而阻断连续激活累积的因素可有效降低错误记忆     

特定句法提示对3－4岁儿童错误信念理解的影响

通过在错误信念任务中,为儿童提供关于错误信念表征的特定句法,考察这种句法理解对儿童的错误信念理解成绩是否有促进作用。124名3-4岁幼儿参加实验,每个年龄组幼儿随机分配到零级提示,一级提示和二级提示等三个句法提示条件组,并完成4个错误信念任务。结果发现,一级提示条件和二级提示条件下的错误信念理解成绩显著高于零级提示条件下的错误信念理解成绩,而一级和二级两种提示条件之间没有显著差异。句法提示对不同的错误信念任务的影响是相同的,对错误信念的预测问题和解释问题的影响模式是一致的。表明对错误信念表征的特定句法提示,有效促进了儿童的错误信念成绩,提示这种句法结构可能有助于儿童的错误信念理解     

识别名人与陌生人面孔的功能磁共振成像

探讨名人与陌生人身份判断的脑功能。6名被试参加实验,运用功能磁共振技术采集数据,AFNI软件进行统计处理。实验结果显示,名人面孔身份识别主要激活了额颞区和梭状回等,陌生人面孔识别主要激活了脑岛和梭状回。实验表明,熟悉名人面孔与陌生人面孔识别有其不同的区域;都有梭状回的视觉加工,但是激活的程度不同。     

中学生适应取向的心理健康结构初探

在文献综述的基础上,建构了适应取向的中学生心理健康的理论模型,并对中学生和中学教师进行开放式问卷调查,再参考同类量表,拟定了中学生心理健康量表的题项。经对1,567名中学生进行测试,结果表明:适应取向的中学生心理健康包含生活幸福、乐于学习、人际和谐、考试镇静、情绪稳定等五个维度,本研究所编制的中学生心理健康量表具有良好的信效度。     

音乐知觉的神经基础研究

音乐知觉涉及基于声音分析、听觉记忆、听觉场景分析、以及音乐的句法和语义加工的复杂的脑神经活动。同时,音乐知觉还潜在的影响情绪、自主神经系统、荷尔蒙以及免疫系统,并激活(前)运动表象。在过去的几年里,音乐加工及其神经关联方面的研究已取得了飞速的进展,主要体现为音乐知觉的神经认知模型、音乐的句法和语义加工、音乐和机体反应等领域的研究。     

Memory and suggestibility in maltreated children: age,stress arousal,dissociation, and psychopathology

The present study was designed to assess children's memory and suggestibility in the context of ongoing child maltreatment investigations. One hundred eighty-nine 3-17-year-olds involved in evaluations of alleged maltreatment were interviewed with specific and misleading questions about an anogenital examination and clinical assessment. For the anogenital examination, children's stress arousal was indexed both behaviorally and physiologically. For all children, individual-difference data were gathered on intellectual and short-term memory abilities, general psychopathology, and dissociative tendencies. Interviewers' ratings were available for a subset of children concerning the amount of detail provided in abuse disclosures. Results indicated that general psychopathology, short-term memory, and intellectual ability predicted facets of children's memory performance. Older compared to younger children evinced fewer memory errors and greater suggestibility resistance. Age was also significantly related to the amount of detail in children's abuse disclosures. Neither dissociation nor stress arousal significantly predicted children's memory. Implications for understanding maltreated children's eyewitness memory are discussed.
