图示写实性对飞机安全须知卡可理解性的影响

本研究使用眼动技术及模拟操作任务考察了图示写实性对飞机安全须知卡可理解性的影响。三组被试分别阅读写实照片、卡通插画、目标实物+其余图画的混合呈现等三种不同呈现形式的安全须知示意图,随后完成模拟操作任务。结果显示,混合组较写实组能更好地引导被试注意投放到与安全操作有关的关键区域上;混合组与写实组的模拟操作绩效均优于卡通组。基于上述结果,笔者建议使用"混合呈现方式"的飞机安全须知卡向乘客传递安全信息。     

中国文化中自尊结构的内隐社会认知研究

本研究同时运用外显的自陈式量表和自行设计的内隐联想测验(IAT)及Go/No-go联想任务(GNAT)来研究中国大学生的自尊结构,结果表明：(1)运用内隐联想测验和Go／No-go联想任务来测量内隐自尊是敏感的;(2)中国文化中自尊是一个双重的结构：包括一个内隐的成分和一个外显的成分。(3)自尊在内隐和外显两个层面上都不存在性别差异。     

人格特质对选择性加工偏向的影响

采用词性辨别和注意探测任务,考察了神经质和外倾性对选择性加工偏向的影响。结果表明：（1）放试在选择信息时存在特质一致性倾向;（2）在单一刺激条件下,当刺激词呈现时间为0．5s时,高神经质对所有效价词的RT均快于低神经质;而当呈现时间为1．0s时,外倾者比内倾者的反应潜伏期更短4（3）双重刺激条件下的选择性加工偏向比单一刺激条件更明显;（4）在词性辨别任务中．刺激词呈现时间只影响了神经质被试对情绪词的RT;在注意探测任务中,呈现时间对内外倾被试的加工偏向影响不显著。

青少年学生生活满意度的结构和量表编制

本研究在文献分析的基础上,结合国外已有的生活满意度量表,通过访谈、开放式问卷等方法,构建了我国青少年学生生活满意度的理论维度,并据此编制了青少年学生生活满意度量表。对量表进行探索性因素分析和验证性因素分析后表明：生活满意度是一个多层次、多维度的结构,包括2个层次和6个维度。

Insufficient augmentation of ambient GABA responsible for age-related cognitive deficit

Age-related degeneration of intracortical inhibition could underlie declines in cognitive function during senescence. Based on a hypothesis that a decrease in basal concentration of ambient (extrasynaptic) GABA with aging leads to depressing intracortical inhibition, we investigated how the basal concentration affects stimulus-evoked activity (as signal), ongoing-spontaneous activity (as noise) of neurons and their (signal-to-noise) ratio S/N. We simulated a neural network model equipped with a GABA transport system that regulates ambient GABA concentration in a neuronal activity-dependent manner. An increase in basal concentration augmented ambient GABA, increased GABA-mediated inhibitory current, and depressed ongoing-spontaneous activity while still keeping stimulus-evoked activity. This led to S/N improvement, for which it was necessary for the reversal potential of GABA transporter to be close to the resting potential of neurons. Above the resting potential, ongoing-spontaneous activity was predominantly enhanced due to excessive GABA-uptake from the extracellular space by transporters. Below the resting potential, stimulus-evoked activity was predominantly depressed, caused by excessive GABA-release. We suggest that the insufficient augmentation of ambient GABA due to a decrease in its basal concentration may be one of the possible causes of cognitive deficit with aging, increasing ongoing-spontaneous neuronal activity as noise. GABA transporter may contribute to improving S/N, provided that its reversal potential is close to the resting potential.     

The use of virtual reality for episodic memory assessment: effects of active navigation

Episodic memory was assessed using Virtual Reality (VR). Forty-four (44) subjects visualized a target virtual apartment containing specific objects in each room. Then they visualized a second virtual apartment comprised of specific objects and objects shared by the two apartments. Subjects navigated in the virtual apartments in one of the following two conditions: active and passive. Four main episodic memory components were scored from the VR exposures: (1) learning effect; (2) active forgetting effect; (3) strategies at encoding and at retrieval; and (4) false recognitions (FRs). The effect of navigation mode (active vs. passive) on each memory component was examined. Active subjects had better learning and retrieval (recognition hits) performances compared to passive subjects. A beneficial effect of active navigation was also observed on the source-based FR rates. Active subjects made fewer source-based FRs compared to passive subjects. These overall results for the effect of active navigation are discussed in terms of the distinction between item-specific and relational processing.     

经验回顾评价中峰-终定律的检验

通过两个实验对经验回顾评价的峰终定律进行检验。实验1借鉴Fredrickson和Kahneman(1993)的实验范式,选取积极和消极视频各6个,要求40名中国大学生边看边评价,看完后给出回顾评价。实验2采用现场研究的方法,要求72名大学生,在黄金周假期中每天晚上评价当天的快乐程度,并分别在假期刚结束后,结束后三周和七周三个时间水平上回顾整个黄金周的快乐程度。结论:短时间内经验回顾评价符合峰-终定律,而长时间内经验回顾评价不符合峰-终定律。
