线索类型对阈下注视线索效应的影响

实验结合连续闪烁抑制范式和线索化范式, 通过操纵直视面孔和斜视面孔的呈现方式, 考察了动静线索类型对注视线索效应的影响。结果表明：两种线索在阈上条件都能产生注视线索效应, 且动态线索诱发的效应更大; 无意识条件下有且仅有动态注视线索能诱发注视线索效应。这说明眼睛运动是产生阈下注视线索效应的必要条件; 眼睛运动会增强阈上注视线索效应, 静态注视线索效应依赖于意识。研究结果支持了社会知觉与心理理论交互模型。     

视觉表象生成系统及其影响因素

视觉表象是在记忆基础上产生的类似知觉的信息表征, 也是人们在日常生活中不可或缺的心理活动之一。本综述介绍了该领域中比较有影响力的表象计算理论模型, 并进一步归纳了视觉表象生成系统的成分及其对应的神经基础。分析结果强调了初级视觉皮层作为“视觉缓冲器”是生成表象的主要机能结构, 以“视觉缓冲器”为基础的表象生成系统的机能受多重因素影响。本综述有助于对视觉表象生成系统形成全面的认识, 促进视觉表象实质的进一步研究。     

前瞻记忆意图后效中执行错误的机制

前瞻记忆意图后效是指已完成或取消的意图失活失败对当前认知任务造成的干扰。近期研究采用前瞻记忆任务范式探究意图后效的影响因素及认知机制。自发提取-抑制失败和预备性监控两种认知机制的分歧在于提取旧意图是否依赖注意资源的参与。脑成像研究也证实意图提取存在两条神经通路：自发提取通路和预备性监控提取通路。未来研究应探索兼容有意遗忘失败、旧意图再提取、抑制失败三者的研究范式以及降低执行错误的有效措施。     

Age-related changes in multi-finger interactions in adults during maximum voluntary finger force production tasks

This study aimed to continue our characterization of finger strength and multi-finger interactions across the lifespan to include those in their 60s and older. Building on our previous study of children, we examined young and elderly adults during isometric finger flexion and extension tasks. Sixteen young and 16 elderly, gender-matched participants produced maximum force using either a single finger or all four fingers in flexion and extension. The maximum voluntary finger force (MVF), the percentage contributions of individual finger forces to the sum of individual finger forces during four-finger MVF task (force sharing), and the non-task finger forces during a task finger MVF task (force enslaving), were computed as dependent variables. Force enslaving during finger extension was greater than during flexion in both young and elderly groups. The flexion-extension difference was greater in the elderly than the young adult group. The greater independency in flexion may result from more frequent use of finger flexion in everyday manipulation tasks. The non-task fingers closer to a task finger produced greater enslaving force than non-task fingers farther from the task finger. The force sharing pattern was not different between age groups. Our findings suggest that finger strength decreases over the aging process, finger independency for flexion increases throughout development, and force sharing pattern remains constant across the lifespan.     

对《大乘起信论》修行方式的初步思考

通过考察认为《大乘起信论》“性觉”修行观体现了中国佛教最根本的修证方式和教化方式,是中国佛教修证和教化的出发点与不可违背的根本前提。中国大乘佛教这种“自性自度”的修证和教化方式,深刻影响并促成了中国传统文化中儒释道三大教化系统对待互补格局的形成和发展。     

周围神经嵌压症诊治过程中的临床思维

运用自然辩证法培养良好的临床思维,指导周围神经嵌压症的诊治过程,有助于获得最佳诊治效果。诊断过程中需全面了解理论知识,学会科学观察,兼顾整体与局部的关系,通过合理分析与综合,可以做出确切诊断。治疗过程中需对有关医师的技术进行评价,采用控制论及系统论方法指导治疗,才能恢复周围神经的结构与功能。     

AQAL模型及其心理学方法论意义

AQAL是美国著名心理学家肯.威尔伯(Ken Wilber)提出的整合研究模型。主张心理学应当拓展研究视野,涵盖主观性、客观性、主体间性、客体间性。认为该模型对解决目前心理学的分裂问题,促进各心理学分支的和谐共生,具有重要的方法论意义。分别讨论了AQAL模型的内涵、提出过程与评价及其心理学方法论意义。     

Fairness and bargaining power in threshold public goods experiments

Experiments on three two‐person threshold public good provision games, namely, the simultaneous, sequential, and dictator games, are conducted to explore the motives behind giving. Players who move simultaneously are endowed with equal bargaining power, and players who move first are endowed with more bargaining power than players who move subsequently. Dictators are indubitably endowed with complete bargaining power. Since the differences between the bargaining powers of two players increase from the simultaneous to the sequential to the dictator game, comparisons among games allow us to trace whether the contribution behavior is motivated by fairness or is simply due to the strategic concern. The experimental evidence shows that the strategic concern explains the overall contribution behavior better than the motive of fairness. However, in the final round 26% of the dictators share the threshold evenly with their opponents, suggesting that some subjects do play fairly. Copyright © 2007 John Wiley & Sons, Ltd.     

C-CAT: A computer software used to analyze and select Chinese characters and character components for psychological research

The Character-Component Analysis Toolkit (C-CAT) software was designed to assist researchers in constructing experimental materials using traditional Chinese characters. The software package contains two sets of character stocks: one suitable for research using literate adults as subjects and one suitable for research using schoolchildren as subjects. The software can identify linguistic properties, such as the number of strokes contained, the character-component pronunciation regularity, and the arrangement of character components within a character. Moreover, it can compute a character’s linguistic frequency, neighborhood size, and phonetic validity with respect to a user-selected character stock. It can also search the selected character stock for similar characters or for character components with user-specified linguistic properties.     

动态范式中基于客体的返回抑制 ——是客体抑制还是空间抑制的动态更新？

对动态范式中基于客体的返回抑制进行了考察。实验1在双侧客体改变和不改变条件下考察了返回抑制效应,结果表明,在双侧客体改变条件下返回抑制仍然存在。实验2采用单侧客体变化技术对动态范式中基于客体的返回抑制进行了测量,结果发现,在有效线索化条件下,单侧客体改变和不改变条件下对靶子的反应时没有显著差异（p > 0.90）。这些结果表明动态范式中基于客体的返回抑制的机制是空间抑制的动态更新,而不是客体表征受到抑制
