信息保持、短时存贮与执行控制的脑模型

工作记忆的脑机制是认知神经科学研究的重要问题。研究者在分析大量脑成像研究数据的基础上,创建了许多解释工作记忆神经基础的模型。Smith和Jonides发展了工作记忆成分结构模型和贮存与执行加工分离模型。Postle和D’Esposito建构了工作记忆相对表征混合模型,D’Esposito, Postle和Rypma阐述了工作记忆加工阶段动态模型。Fletcher和Henson提出工作记忆额叶分区整合理论。该文通过对上述模型或理论的评价,总结了工作记忆脑成像研究中存在的问题,展望了该研究领域的发展趋势。

Cloninger's Temperament and Character Inventory Correlates with Personality Characteristics of Organ Donation Advocates

Temperament and Character Inventory (TCI) and background questionnaire data were collected from a sample of men and women organ donation advocates (N = 362) as part of a national study to investigate their personality characteristics, temperaments, and attitudes about organ donation advocacy. Goals included identifying unique traits for advocates, and response consistency between the TCI and questionnaire. The TCI results included high scores on Cooperativeness and Self-Directedness, and low on Harm Avoidance dimensions. The questionnaire results indicated that most advocates were White, married, college-educated females, who typically spent less than 2 hr with potential donor families, were satisfied with life and job, and believed they would be in a donation position 2 years from the time surveyed. TCI and questionnaire measures were correlated for Self-Transcendence and Spirituality, Helpfulness and Job Satisfaction, and Compassion and Identification variables.     

陌生的邻居:东正教之于中俄相互认知上的障碍性角色

在中俄战略协作伙伴关系的框架下,双方的确没有出现如中美或中国与欧盟之间那样的纷争和冲突,但也缺乏中美、中欧之间相互深刻影响对方的社会进程、经济发展和生活方式变革等积极成果。造成这种矛盾现象的因素固然复杂,但俄罗斯东正教作为远远超出宗教领域的巨大存在,影响着后苏联社会进程的每个方面,却不能被中俄战略协作伙伴关系所考虑,这在客观上必然影响俄中关系,应该是这种战略实施后果不很理想的重要原因。本文探讨两个问题:俄罗斯东正教之于后苏联的超常重要性,以及,中国对俄国的认知绕开东正教因素和无神论政策是不可能的。

幻忆现象研究现状述评

幻忆(Déjà vu)是指任何对目前体验的一种不适宜的熟悉感, 并伴随着对过去体验的不确定感。年龄、梦、教育水平、旅行经历、生理状况和药物都会对幻忆产生造成影响。研究发现, 内侧颞叶和嗅内皮质与幻忆有着紧密的联系。目前主要通过知觉分离范式、情景再现范式、单成分元素交互作用范式、无辨别再认范式和催眠范式来研究幻忆现象。幻忆的研究仍然存在着若干问题, 这些问题需要进一步探讨。     

Association of catechol-O-methyltransferase (COMT) polymorphism and academic achievement in a Chinese cohort

Catechol-O-methyltransferase (COMT) is a methylation enzyme that catalyzes the degradation pathway and inactivation of dopamine. It is accepted widely as being involved in the modulation of dopaminergic physiology and prefrontal cortex (PFC) function. The COMT Val158Met polymorphism is associated with variation in COMT activity. COMT 158Met allele may be advantageous for PFC-related cognitive abilities; however, it is also associated with increased anxiety, depression, and emotional vulnerability in response to stress or educational adversity. We hypothesized that the COMT polymorphism might be associated with academic performance. In this study, 779 Taiwanese tenth-grade volunteers were recruited. Scores from the Basic Competency Test (BCT), an annual national competitive entrance examination, were used to evaluate academic performance. The results indicated that students bearing homozygous for the Met allele tended to perform more poorly in all BCT subtests as compared to the other groups. In particular, the former performed significantly more poorly in the science and social science subtests. These findings provide evidence that affective factors might overwhelm cognitive abilities in high-stake tests like the BCT.     

任务切换机制研究的理论争议与整合

任务切换是执行控制的一种重要功能。切换代价是量化执行控制持续时间的指标。并广泛应用于各个研究领域。但是切换代价在多大程度上体现了执行控制的作用,仍然还存在争论．当前主要存在任务设置重构、任务设置惯性和联结竞争三种理论。本文首先介绍了三种理论的基本观点和实验证据,以及对任务切换加工机制的分析;其次阐明了对三种理论进行整合的相关研究;最后分析了进一步研究的方向。     

Systematic behavior research for understanding consumer decision making

This study incorporates means—end chain (MEC) theory and dynamic programming for understanding the implications of consumer decision making. The conceptual framework of this study can help programmers design information systems for analyzing consumption behaviors. Such analyses will provide marketers with meaningful information for formulating marketing strategies. The main contributions of this article are as follows: (1) to enable researchers to obtain information for consumer cognitive hierarchies utilizing an information system, (2) to enhance the functions of traditional MEC methodology and provide an integrated method for analyzing consumption information, and (3) to construct an information system for analyzing consumer decision-making processes.
