Rapid contact call-driven induction of NR2A and NR2B NMDA subunit mRNAs in the auditory thalamus of the budgerigar (Melopsittacus undulatus)

In situ hybridization histochemistry was used to assess the effect of auditory stimulation with natural contact calls on expression of NR2A and NR2B NMDA subunit mRNAs in neurons of the thalamic auditory relay nucleus ovoidalis (Ov) of a vocal learning parrot species, the budgerigar (Melopsittacus undulatus). The results showed that both the core (Ov) and ventromedial shell subdivisions (Ovm) of ovoidalis contained neurons expressing NR2A and NR2B mRNA in no-stimulation control subjects and that the distributions of neurons expressing these subunit mRNAs were very similar in both the core and shell of Ov. Contact call stimulation (5, 30 and 180 min) resulted in substantial increases of 50-60% in the number of neurons expressing NR2A and NR2B mRNAs in both the core and shell. Staining intensity, as measured by the optical density of stained somata approximately doubled compared to controls for both NR2 subunits in the 5 and 30 min conditions, but declined from 30 to 180 min. In all conditions, the density, but not staining intensity, of neurons expressing NR2B exceeded NR2A expression. Furthermore, the density of neurons expressing both subunit mRNAs in call stimulation conditions was greater in the core than in the shell despite the fact that total neuronal density was approximately 20% higher in the shell. Previous experiments have shown that call stimulation is more effective at inducing expression of the immediate early gene zenk in the Ov shell than core; however the present results do not indicate that either NR2A or NR2B mRNA expression mediates this effect since neither subunit exhibits greater expression in Ovm. Ca(++) release is needed for immediate early gene expression, however and, notably, Ovm contains large numbers of neurons containing CGRP, a peptide which has been shown to increase cytosolic Ca(++) levels.     

Progressive age-related changes in the attentional blink paradigm

Previous studies on aging and attention typically examine group differences between younger and older adults, rather than seeing aging as a continuous process. Using correlational analyses, this study examined progressive changes in the magnitude of the attentional blink (AB) associated with aging. Increased age was found to be significantly associated with the ability to detect the second target (T2), whereby older age was correlated with the production of a longer and more pronounced AB; this supports the proposition that aging is associated with reduced inhibitory processes and selective attention. It was also found that AB performance somewhat improves between ages 18-39 years, but tends to decline from 40 years of age onward, providing an interesting and novel finding that AB effects may become more sensitive at this point in time. The AB task may prove useful in the assessment of selective attention in normal healthy adults, as well as changes associated with pathological aging.     

工作－家庭界面研究的新视角：工作家庭促进研究

工作家庭促进关注的是工作－家庭关系中的积极方面,指的是个体由于在某一社会系统（工作或者家庭）中的投入,而对另一系统（如家庭或者工作）的发展产生贡献的程度。文章首先探讨了工作家庭促进的理论源流、概念界定以及三个主要的研究方向;接下来介绍了基于系统论思想的促进发生机制模型;最后指出了今后两个首要的研究方向,即工作家庭促进测量工具的开发及其与相关变量的关系研究     

基于因子分析的创业策略之探索性研究

本研究采用二阶因子分析方法(CFA),对苏州、上海两地的各类型创业企业进行了探索性研究,借鉴国内外通用的创业策略维度,对于200多家苏州、上海两地企业的创业策略进行探索性因子分析。本文采用结构方程(SEM)"建模"的方法,采用LISREL8.7软件编程设计,最终得出中国背景下企业创业策略中包括竞争策略、创新策略、社区策略、服务策略、组织策略、政府策略以及发展策略7个维度。本研究结果对于创业型企业在制定创业策略时有重要意义。     

新媒体研究述评及其心理学研究取向

新媒体的横空出世,对人们的生活带来极大影响。针对新媒体自身的一些问题及其影响,国内外进行了一系列研究。在综观相关研究成果基础上,介绍了新媒体的内涵与外延、特征及新媒体时代的起始时间,并主要介绍了新媒体的研究焦点,包括新媒体对人们生活方式及生活质量的影响,影响人们对新媒体态度及行为背后的心理因素分析。最后,在综合评价已有研究的基础上,提出应进一步加强新媒体的心理学研究取向,同时指出新媒体研究问题的具体深入化、方法的多元化及研究的本土化是未来的研究趋向。     

不一致性重读对口语语篇加工中信息激活水平的影响

利用跨通道词汇再认任务,探索了口语临场加工过程中,不一致性重读对新信息以及它所标示的旧信息在语篇表征中激活的影响。结果表明：与控制条件相比,不一致性重读虽然提高了旧信息在语篇表征中的激活水平,但是同时抑制了新信息的激活;这一促进和抑制作用在关键词汇后的500 ms就已出现。从而说明,对于相对重要的新信息,不一致性重读会阻碍语篇的理解,并且会影响到语篇的临场加工过程。     

个体早期情绪唤起与自我决定及主观活力的关系

以量表测量法初步探索早期情绪唤起与成年后自我决定水平及主观活力之间的关系,试图寻找情绪对人格组织的核心作用的证据。研究发现：①个体在早期父母行为调控中的某些基本情绪的唤起可以有效预测其成年后的自我决定和主观活力水平。②个体早期抵触情绪唤起对其成年后的自我决定和主观活力具有消极作用,而非负性情绪唤起则具有积极作用。研究结果支持基本情绪理论关于情绪处于人格结构的核心地位的观点。     

心率变异性在心身疾病和情绪障碍研究中的应用

心率变异性的频谱成分可单独反映交感神经和副交感神经活动的影响。高频（HF）是由迷走神经单独介导；低频（LF）受迷走神经和交感神经共同调制，但主要反映交感神经的活动性 。此指标可对高血压、冠心病和月经前期烦躁等心身障碍进行评价。该文还探讨了它用于情绪研究的价值，并认为在不同情绪体验期间的自主神经活动有多种搭配模式，正常人与情绪障碍者之间以及情绪障碍（抑郁、焦虑、恐怖、强迫）患者在自主神经活动方面可能存在显著差别     

非目标工作记忆表征下颜色关联和抽象关联的注意捕获和抑制

采用工作记忆—视觉搜索双任务范式,探讨在非目标工作记忆表征下,颜色关联和抽象关联干扰子的注意捕获和抑制现象。实验一结果发现,颜色关联干扰子在快速反应阶段捕获注意,随后被成功抑制;抽象关联干扰子仍能捕获注意。实验二消除知觉凸显后,结果发现颜色关联条件的抑制消失,干扰子重新捕获注意。结果表明,有效抑制策略受不同关联干扰子加工先后顺序的影响,选择性抑制颜色关联干扰子,而颜色特征的凸显有助于抑制策略形成。
