早期ERP效应与视觉注意空间等级的脑调节机制

通过事件相关电位(ERP)记录研究注意的空间等级的脑内时程动态变化。视觉搜索任务的目标受不同大小提示范围的启动。提示范围增大时,识别目标的反应时延长,P1波幅增大而N1波幅减小,该效应在短间隔条件下尤为明显。P1增大反映了促进目标识别时,适当注意范围的空间等级变化需要额外的运算资源。而N1波幅减小则可能扩散了空间注意倾斜。研究结果提供了以下电生理学证据：注意空间等级的改变调节了早期视皮层的神经活动,并激活了视觉搜索中至少2个时间重叠的ERP成分。     

形状-宜人性的内隐联结及其对公平决策的影响

已有研究表明,形状感知与抽象概念之间具有隐喻联结并能够影响个体的判断与决策。当前研究在此基础上提出,不同形状与人格的宜人性存在关联且能够影响个体决策。实验1采用内隐联想范式的变式探讨不同形状与宜人性词汇之间的联系,结果未发现长方形和圆形与宜人性词汇存在内隐联结。实验2采用内隐联想测验探讨圆润面孔与棱角面孔与宜人性词汇之间的联系,结果发现圆润面孔与宜人词、棱角面孔与非宜人词之间存在内隐联结。实验3进一步考察形状与宜人性词汇的联结对公平决策的影响,结果发现圆润面孔更易知觉为宜人,个体更容易接受其作出的不公平分配,而棱角面孔更易知觉为非宜人,个体更容易拒绝其作出的不公平分配; 并且,宜人性感知在面孔形状与被试的接受率之间起中介作用。研究结果表明,圆润形状面孔与宜人词、棱角形状面孔与非宜人词存在隐喻联结,且这一联结能够进一步影响个体公平决策。     

虚拟路径整合的学习效应

路径整合指通过自身运动信息对自身位置进行更新的过程。本研究使用头盔式虚拟现实系统和分段式迷宫, 在两个实验中检验在同样布局的外出路径上重复地进行路径完成任务是否会改善被试的反应表现。实验1中的外出路径具有相对较简单的空间布局, 实验结果表明, 男性和女性被试均在反应时、位置误差、角度误差上表现出了学习效应, 即第二次在同样空间布局的外出路径上进行路径完成任务时的表现比第一次有了显著的改善。实验2中的外出路径具有更复杂多样化的空间布局, 而实验结果表明, 男性和女性被试均在反应时和比例位置误差上表现出了学习效应, 但是路径更复杂时要求更多次数的重复才可以提高路径整合成绩。这些研究结果为路径整合能力训练的可行性提供了初步的实证依据。     

Water,Plant, Light,and Mirror: On the Root Metaphors of the Heart-Mind in Wang Yangming’s Thought

Clarifying Wang Yangming’s thought through a study of his root metaphors of heart-mind is an important step toward explaining his further concepts of the human world. Along with the root metaphors of water and mirror, the metaphors of plant and light work together for Wang to form a coherent theoretical and practical system of xin (heart-mind). This method is also a good way to unravel the various theories of the “three teachings” that are intermingled in his thinking. By using this methodology Wang’s attempts to harmonize several ancient traditions of heart-mind that appear as possibly polarized to modern readers, are illuminated (though they did not appear contradictory to the Neo-Confucians).     

权力概念加工对视觉空间注意定向的影响：一个ERP证据

概念表征是认知心理学研究的一个重要领域。具身认知理论认为, 在概念加工过程中, 个体会以具身模拟的形式对概念所暗含的空间方位信息进行理解。本研究采用事件相关电位技术, 考察抽象权力概念加工时的激活特点。实验首先要求被试对出现在屏幕中央的词进行权力高/低判断, 接着在屏幕的上方或者下方呈现一个字母(“m”或“n”), 要求被试对目标物进行按键反应。结果发现, 当权力词隐喻的空间特性与目标物出现的位置一致时诱发了一个更大的N1波幅, 不一致时诱发了一个更大的P3波幅。该结果提示, 抽象权力概念加工时会产生自动激活空间上-下意向图示, 对权力词的加工影响了随后字母位置的判断, 并将空间注意指向了与意向图示相一致的位置, 从时间加工进程看, 起始于早期的知觉识别并一直持续到晚期的高级认知加工阶段, 权力概念加工具有内隐性。     

Improving left spatial neglect through music scale playing

The study assessed whether the auditory reference provided by a music scale could improve spatial exploration of a standard musical instrument keyboard in right‐brain‐damaged patients with left spatial neglect. As performing music scales involves the production of predictable successive pitches, the expectation of the subsequent note may facilitate patients to explore a larger extension of space in the left affected side, during the production of music scales from right to left. Eleven right‐brain‐damaged stroke patients with left spatial neglect, 12 patients without neglect, and 12 age‐matched healthy participants played descending scales on a music keyboard. In a counterbalanced design, the participants' exploratory performance was assessed while producing scales in three feedback conditions: With congruent sound, no‐sound, or random sound feedback provided by the keyboard. The number of keys played and the timing of key press were recorded. Spatial exploration by patients with left neglect was superior with congruent sound feedback, compared to both Silence and Random sound conditions. Both the congruent and incongruent sound conditions were associated with a greater deceleration in all groups. The frame provided by the music scale improves exploration of the left side of space, contralateral to the right hemisphere, damaged in patients with left neglect. Performing a scale with congruent sounds may trigger at some extent preserved auditory and spatial multisensory representations of successive sounds, thus influencing the time course of space scanning, and ultimately resulting in a more extensive spatial exploration. These findings offer new perspectives also for the rehabilitation of the disorder.     

心理治疗中隐喻的使用、疗效检验及作用机制

隐喻是用一种具体、熟悉的概念去表达和理解一种抽象、不熟悉的概念的语言形式和认知方式,因其在心理治疗中可以有效传递治疗信息而被治疗师们广泛使用。早期的隐喻理论阐述了隐喻具有高创造性和增强长时记忆的认知加工优势,虽然不同心理治疗流派在治疗过程中对使用来访者还是治疗师产生的隐喻各有侧重,但它们都认为隐喻可以通过高创造性的内容、形成更优的长时记忆以及带来高度的认知卷入来帮助咨访双方有效加工、传递和保存治疗信息。精神分析流派强调治疗性隐喻在无意识水平上的意义交换产生的顿悟过程,认知行为疗法既强调隐喻可以促进认知图式的重构,也强调其组块性和形象性产生的记忆功能,接纳与承诺疗法认为隐喻传递信息时具有非评判、非分析、直觉经验的方式有利于促进个体发生改变,后现代疗法中强调让来访者重新叙述自己的人生故事或者发展出一种形象性或象征性表达,让来访者产生更具有功能的观点和看法。因此治疗性隐喻具备了跨越不同心理治疗理论取向的广泛认同基础。在实证研究上,大多数研究聚焦于探索在某种治疗方法中加入隐喻是否会有更佳的治疗效果,其中使用CBT作为框架的研究最为集中,有些研究发现隐喻干预在缓解心理症状方面优于常规干预,也有研究发现隐喻干预和非隐喻干预都可以有效缓解被试的心理痛苦,因此虽然没有获得十分一致的结论,但这些研究总体上证明了在心理治疗中使用隐喻是有效的。随着研究的深入,对治疗性隐喻起效的心理神经机制进行探索的实证研究也有效观测到了隐喻理论中提出的认知加工优势,包括隐喻的高创造性可以诱发顿悟（并伴随杏仁核、海马、梭状回等特异性神经网络的显著激活）、带来更佳的治疗效果,隐喻内容更容易被记住、有助于治疗持续发挥作用,以及隐喻可以增加来访者的认知卷入程度进而带来更大程度的认知改变。综上,无论从理论构建还是实证证据上,治疗性隐喻都是一种具有独特认知加工优势的认知工具和治疗信息传递途径。未来研究可以从更加科学的设置对照组、增加隐喻特异性的效果衡量指标以及探索其他可能的心理机制三个方面来进一步观察在治疗性隐喻的独特优势。最后,对在心理治疗实践中更好的使用隐喻以及研发嵌入隐喻的低成本高效益的社会心理健康服务方案提供了建议。     

Decay of Stimulus Spatial Code in Horizontal and Vertical Simon Tasks

Evidence on the processes underlying the horizontal and vertical Simon effect is still controversial. The present study uses experimental manipulations to selectively delay the stages of response execution, response selection, and stimulus identification in three experiments. A reduction is observed for both horizontal and vertical Simon effects when response execution is delayed by a go-signal presented 400–600 ms post-stimulus onset or when a spatial precue is presented 200–400 ms before the stimulus. When the overlap between stimulus spatial code formation and response selection is prevented by decreasing stimulus discriminability, the horizontal Simon effect decays, but the vertical Simon effect does not change. Activation theories, which propose a decay of the automatically activated response ipsilateral to the stimulus, mainly apply to the horizontal Simon effect. In contrast, translation theories, which propose that the effect occurs when stimulus features are translated into a response code, are more suitable to account for the vertical Simon effect.     

The development of spatial category representations from 4 to 7 years

Representation of spatial categories was assessed in 4‐ to 7‐year‐olds. Across nine spatial categories (In, On, Under, In Front, Behind, Above, Below, Left, and Right), children were asked to pick the odd‐one‐out from four images, three of which displayed the same spatial relationship between two objects, and one which showed a different spatial relationship. Results support our proposed model of spatial category representation. Children progressed through three levels of understanding: from rigid (level 1), to abstract (level 2) to broad (including non‐prototypical category exemplars) (level 3) understanding of spatial category membership. This developmental pattern was common to all spatial categories, and the ages at which children reached each level varied across categories, in line with the order in which category representations emerge in infancy.     

两维特征图形的客体和空间工作记忆存储研究

研究采用单探测变化检测范式,考察了两维特征图形在视觉客体和视觉空间工作记忆中的存储机制,并对其容量进行测定。40名被试(平均年龄20.56±1.73岁)随机分为两个等组,分别完成实验一和实验二。实验一的刺激图形由颜色和形状两基本特征组成,实验二的刺激为由不同颜色和开口朝向组成的兰道环。两个实验结果均显示:(1)特征交换变化条件下的记忆成绩与单特征变化条件下最差的记忆成绩差异不显著;(2)空间工作记忆任务的成绩显著优于客体工作记忆任务;(3)被试在视觉工作记忆中能存储2~3个客体和3~4个空间位置。这表明,由两种不同维度特征组成的图形在视觉客体和视觉空间工作记忆中均以整合方式进行存储,空间工作记忆的容量大于客体工作记忆。
