An analysis of immediate serial recall performance in a macaque

There has been considerable research into the ability of nonhuman primates to process sequential information, a topic that is of interest in part because of the extensive involvement of sequence processing in human language use. Surprisingly, no previous study has unambiguously tested the ability of nonhuman primates to encode and immediately reproduce a novel temporal sequence of perceptual events, the ability tapped in the immediate serial recall (ISR) task extensively studied in humans. We report here the performance of a rhesus macaque on a spatial ISR task, closely resembling tasks widely used in human memory research. Detailed analysis of the monkey’s recall performance indicates a number of important parallels with human ISR, consistent with the idea that a single mechanism for short-term serial order memory may be shared across species.

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。     

家电销售人员胜任特征模型建构

本研究旨在探讨优秀家电销售人员应具备的胜任特征。首先通过对20名家电销售人员的行为事件访谈,初步构建了家电销售人员胜任特征模型;然后通过对20例顾客与家电销售人员的互动进行自然观察,进而对所建构的模型加以验证。研究表明,家电销售人员胜任特征模型共包括9项:成就导向、主动性、学习发展、影响力、洞察力、服务意识、可信赖、情绪稳定性以及产品知识。     

三种压力与创意自我效能感对创造力的影响

以216名初中二年级学生为被试,采用现场实验,探讨个体创意自我效能感在竞争、评价和时间三种压力情境下对创造力的影响。结果发现,三种压力对于总体创造力的影响不同;时间、评价压力分别提高了流畅性和新颖性,竞争压力既提高了流畅性又提高了新颖性,但三种压力情境都降低了变通性;创意自我效能感中间组的学生在压力情境下具有最好的变通表现,而效能感低分组表现最差。     

人格特质与主观幸福感:情绪调节的中介作用

通过对1163名大学生被试进行人格特质、情绪调节策略的使用以及主观幸福感的测查,本研究探讨了气质性人格特质(神经质和外倾性)这种稳定的内在心理结构对主观幸福感产生影响的可能机制。结果发现:(1)除直接影响个体的主观幸福感外,神经质和外倾性还会通过重新评价策略的使用间接影响主观幸福感;(2)人格特质和重新评价策略的使用可以有效预测个体主观幸福感的变异;(3)习惯性地使用表达抑制策略对个体的主观幸福感并没有显著的影响。这些结果表明重新评价策略的使用在人格特质对主观幸福感的影响中具有重要的中介作用。该发现对进一步制定改善和提高个体的主观幸福感的干预措施具有重要的启示和指导意义。     

管子社会控制思想及其现实意义

齐国法家及其代表论著《管子》中包含着丰富的社会控制思想。《管子》一书在顺民心的前提下,主张运用法治制衡,培养民众礼节来进行社会的合理控制。在整个中国古代历史上,《管子》所倡导的礼法结合的社会控制手段是最为有效完善的。《管子》从治国实践的角度认为,要真正做到"以民为本",对国家和百姓进行合理的控制安排,实现百姓安居,国家长治,在治国方略上就必须礼法并用,德法并举:一方面以法来维护人民的利益,另一方面以"礼"来维护社会秩序。《管子》礼法并举的社会控制思想在构建和谐社会、减少社会道德失衡等方面具有重要的现代价值及意义。     

厄洛斯神话的哲学启示

The myth of Er at the end of Plato's Republic is usually conceived as an eschatological one set in a philosophical context.It thus reveals the relationship between philomythos and phylosophos,and the interaction between myth and philosophy in a creative manner.Engaging and thought-provocating as it is,it is deployed to stir much reflection on the possible aspects of the human soul in terms of justice and injustice.In addition,it well demonstrates how Plato applies it as one of many typical cases to his post...     

Ursolic acid attenuates lipopolysaccharide-induced cognitive deficits in mouse brain through suppressing p38/NF-κB mediated inflammatory pathways

Evidence indicates that systemic administration of lipopolysaccharide (LPS) induces brain inflammation, ultimately resulting in cognitive deficits. Ursolic acid (UA), a plant-derived pentacyclic triterpenoid, is well known to possess multiple biological functions, including antioxidant, anti-tumor and anti-inflammatory activities. In the present study, we assessed the protective effect of UA against the LPS-induced cognitive deficits in mice. We found that UA significantly improved cognitive deficits of LPS-treated mice in open field, step-through passive avoidance and Morris water maze tasks. One potential mechanism of this action was attributed to the decreased production of pro-inflammatory markers including COX-2, iNOS, TNF-α, IL-1β, IL-2 and IL-6 in LPS-treated mouse brain. Mechanistically, UA markedly inhibited LPS-induced IκBα phosphorylation and degradation, NF-κB p65 nuclear translocation and p38 activation in mouse brain, but did not affect the activation of TLR4, MyD88, ERK, JNK and Akt. Taken together, these results suggest that UA may be useful for mitigating inflammation-associated brain disorders by inhibiting pro-inflammatory factors production, at least in part, through blocking the p38/NF-κB signaling pathways.     

Longitudinal Changes in Acculturation for Immigrant Women from the Former Soviet Union

Most research on immigrant acculturation has been conducted with cross-sectional samples, using statistical designs that may not capture different trajectories for the components that contribute to this complex concept. The purpose of this study was to examine change over time in acculturation for 226 women from the former Soviet Union who had lived in the US fewer than eight years when recruited. Using self-report data from four annual waves, growth trajectories were examined in four components of acculturation (American behavior, Russian behavior, English language proficiency, and cultural generativity). Results indicate that these components changed at varying rates. Acculturation is a process with multiple distinct components which should be measured separately to obtain a full profile of change over time.
