“在场的”科学主体及其认知模式

传统上对科学的看法常常因为主体与客体绝对的二元对立而陷入困境,这个困境使得科学的真理观要么滑向客观主义的绝对主义,要么滑向主观主义的相对主义;这两种立场都没有恰当地反映出主体在科学实践中的恰当地位和作用。我们将以上述方式所看待的主体称为不在场的(non-present)     

私人复制著作权问题的立法规制透视——兼论我国《著作权法》之完善

私人复制著作权问题是随着复制技术进步而带来的.在数字和网络技术普及之前,国际上对私人复制问题的讨论主要围绕影印复制、家庭录制等问题展开.随着数字和网络技术的发展,则关注点集中于数字和网络环境下私人复制问题.在国际立法中,"三步检验法"成为规制和衡量包括私人复制在内的复制行为的重要立法成果.私人复制问题反映了复制权保护、限制与技术变革的互动关系.为因应复制技术变革,一些国家著作权立法逐渐完善了私人复制制度.我国著作权法修改在即,如何完善相应规定值得深入研究.     

怀旧与怀古:从心理到文化

无论是怀旧还是怀古,我们都不陌生。即使一个人对之没有深刻的体会,也可能从古今众多的文学作品尤其是诗歌中,领略过相关的情怀。不过,人们熟悉的现象,只能说明它具有普遍性,并不意味着我们真正理解它。依哲学的观点,只有通过深入的反思,才能揭示这些意识活动的深层意义。本文的努力,是把怀旧与怀古当作一种心理-文化的关联现象来理解。依次论述     

齐地对个体勇士的崇尚及其文学表现——以《左传》的战争叙事为例

《左传》塑造了众多尚力崇勇的齐国勇士,他们注重于对个人功名的争取,具有英雄气概和冒险精神。长于单打独斗而怯于众斗,成为齐文化的重要特色。《左传》的战争叙事,对此作了生动地展现。     

任务类型对上下视野优势的影响

视觉信息加工的单侧视野优势效应一直是认知心理学领域的研究热点。本研究采用变化检测范式探讨文字和几何信息在上下视野中的优势效应。结果发现：当加工文字材料时,颜色和位置检测任务均出现上部视野优势效应;加工几何图形时,则出现下部视野优势效应。上述结果表明,任务信息所需要的加工类型影响上下视野的优势效应,支持Previc提出的视野优势效应的生态假说。     

作为效应的ERP研究

晚正成分能够反映不同效价和不同唤醒度的情绪。作为后悔的一种现象,作为效应是否与晚正成分具有关联是研究关心的问题。采用运气轮博弈的范式,记录与分析被试在“做”与“不做”决策下的ERPs。研究发现,决策结果的正误显著影响了FRN、P300和LPC的波幅大小。作为类别对FRN、P300和LPC波幅的影响受到不同决策结果的影响,在决策正确的条件下,作为类别对FRN、P300和LPC波幅不产生影响,而在决策错误的条件下,作为类别对FRN、P300和LPC波幅产生了显著的影响。结果表明作为效应不仅影响了FRN、P300的波幅,同时也影响了LPC的波幅,将来研究应进一步探明晚正成分与后悔的密切关联。

Unconscious structural knowledge of form-meaning connections

We investigated the implicit learning of a linguistically relevant variable (animacy) in a natural language context (namely, the relation of forms of determiners to semantics). Trial by trial subjective measures indicated that exposure to a form–animacy regularity led to unconscious knowledge of that regularity. Under the same conditions, people did not learn about another form–meaning regularity when a linguistically arbitrary variable was used instead of animacy (size relative to a dog). Implicit learning is constrained to acquire unconscious knowledge about features with high prior probabilities of being relevant in that domain.     

Selective inactivation of adenosine A(2A) receptors in striatal neurons enhances working memory and reversal learning

The adenosine A(2A) receptor (A(2A)R) is highly enriched in the striatum where it is uniquely positioned to integrate dopaminergic, glutamatergic, and other signals to modulate cognition. Although previous studies support the hypothesis that A(2A)R inactivation can be pro-cognitive, analyses of A(2A)R's effects on cognitive functions have been restricted to a small subset of cognitive domains. Furthermore, the relative contribution of A(2A)Rs in distinct brain regions remains largely unknown. Here, we studied the regulation of multiple memory processes by brain region-specific populations of A(2A)Rs. Specifically, we evaluated the cognitive impacts of conditional A(2A)R deletion restricted to either the entire forebrain (i.e., cerebral cortex, hippocampus, and striatum, fb-A(2A)R KO) or to striatum alone (st-A(2A)R KO) in recognition memory, working memory, reference memory, and reversal learning. This comprehensive, comparative analysis showed for the first time that depletion of A(2A)R-dependent signaling in either the entire forebrain or striatum alone is associated with two specific phenotypes indicative of cognitive flexibility-enhanced working memory and enhanced reversal learning. These selective pro-cognitive phenotypes seemed largely attributed to inactivation of striatal A(2A)Rs as they were captured by A(2A)R deletion restricted to striatal neurons. Neither spatial reference memory acquisition nor spatial recognition memory were grossly affected, and no evidence for compensatory changes in striatal or cortical D(1), D(2), or A(1) receptor expression was found. This study provides the first direct demonstration that targeting striatal A(2A)Rs may be an effective, novel strategy to facilitate cognitive flexibility under normal and pathologic conditions.     

"Dwelling in the Past": The Role of Rumination in the Treatment of Posttraumatic Stress Disorder

Prolonged exposure, a cognitive behavioral therapy including both in vivo and imaginal exposure to the traumatic memory, is one of several empirically supported treatments for chronic posttraumatic stress disorder (PTSD). In this article, we provide a case illustration in which this well-validated treatment did not yield expected clinical gains for a client with PTSD and co-occurring major depression. After providing an overview of the literature, theory, and treatment protocol, we discuss the clinical cascade effect that underlying ruminative processes had on the treatment of this case. Specifically, we highlight how ruminative processes, focusing on trying to understand why the traumatic event happened and why the client was still suffering, resulted in profound emotional distress in session and in a lack of an "optimal dose" of exposure during treatment.
