客体投影方式对空间问题解决和再认的影响

通过设置四种实验条件,旨在阐明空间问题解决和再认的水平是如何受到客体不同投影方式的影响。除进一步支持了正投影问题的解决是以一个具有三维结构特性的心理表征为基础而并非是对二维正投影信息进行了充分识别的观点外,研究结果还表明：（１）这个具有客体三维结构特性的心理表征是建构于对正投影问题解决而非轴测投影图的再认过程中;（２）正投影问题解决的复杂性显著地高于轴测投影图问题解决而且一个建构于正投影问题解决中     

顶叶在特征捆绑中的作用--对一例典型双侧顶叶损伤病人的研究

本实验以一例典型双侧顶叶损伤患者为研究对象,以数字和几何形状为材料,采用形状和颜色特征识别任务,主要考察了顶叶及空间信息是否影响视觉特征捆绑。结果显示,患者在特征捆绑任务上操作成绩较差,错觉性结合错误远远多于特征错误,且正确反应及错觉性结合受刺激间的距离及呈现方式的影响,表现出距离和位置效应。这些结果表明,顶叶在视觉特征捆绑中起重要作用,这种影响作用很可能与空间注意有关。本研究进一步为特征整合理论提供了神经心理学的证据。     

室内照度和时间对警觉性和视空绩效的影响

本研究考察了白天室内照度和测验时间对个体视空工作记忆和视空能力及主观情绪和警觉性的影响。采用2(高/低照度水平)×2(上午/下午)混合设计,结果发现：被试在高照度水平下的柯西块任务的正确率更高,警觉反应更快,且尤其体现在下午时段;而不同照度水平对点记忆任务、视空能力测验和主观情绪无显著影响。结果表明白天室内照度能够影响个体的视空工作记忆和警觉性,主要表现在高照度照明环境的积极作用上,而对个体的视空能力及情绪变化影响微弱。     

内源性空间注意对声音诱发闪光错觉的影响

采用经典的声音诱发闪光错觉范式,通过操纵集中和分散的空间注意的方式,考察内源性空间注意和刺激出现视野位置的交互作用对多感觉整合中听觉主导效应的影响。结果发现：(1)当空间注意处于分散状态时,下视野的裂变错觉量显著大于上视野,而集中条件下则没有差异。(2)闪光出现的位置是否随机不会影响裂变错觉。研究说明了声音诱发闪光错觉中的裂变错觉只会受到内源性空间注意和视野位置交互作用的影响。     

Spatial attention based on 2D location and relative depth order modulates visual working memory in a 3D environment

The attentional effect on visual working memory (VWM) has been a heated research topic in the past two decades. Studies show that VWM performance for an attended memory item can be improved by cueing its two-dimensional (2D) spatial location during retention. However, few studies have investigated the effect of attentional selection on VWM in a three-dimensional setting, and it remains unknown whether depth information can produce beneficial attentional effects on 2D visual representations similar to 2D spatial information. Here we conducted four experiments, displaying memory items at various stereoscopic depth planes, and examined the retro-cue effects of four types of cues – a cue would either indicate the 2D or depth location of a memory item, and either in the form of physical (directly pointing to a location) or symbolic (numerically mapping onto a location) cues. We found that retro-cue benefits were only observed for cues directly pointing to a 2D location, whereas a null effect was observed for cues directly pointing to a depth location. However, there was a retro-cue effect when cueing the relative depth order, though the effect was weaker than that for cueing the 2D location. The selective effect on VWM based on 2D spatial attention is different from depth-based attention, and the divergence suggests that an object representation is primarily bound with its 2D spatial location, weakly bound with its depth order but not with its metric depth location. This indicates that attentional selection based on memory for depth, particularly metric depth, is ineffective.     

道德概念垂直空间隐喻的心理现实性及双向映射

研究以大学生为被试,通过三个实验考察道德概念垂直空间隐喻的心理现实性及双向映射。实验1采用面孔图片和道德词汇的匹配记忆任务发现,道德词出现在上方时,被试对词语和面孔的匹配再认率更高;不道德词出现在下方时,被试对词语和面孔的匹配再认正确率更高。结果证实了道德概念的垂直空间隐喻的心理现实性。实验2通过道德评价任务发现,被试倾向于把空间上方出现的面孔评价为更加道德,把在空间下方的面孔评价为更加不道德,证实了空间信息对道德评价的影响。实验3采用带有空间位置信息的词语记忆任务。结果表明,在位置判断任务中,被试更多地将道德词判断为在上方出现过,更多地将不道德词判断为在下方出现过。结果显示词语的道德色彩影响了空间信息判断。研究结论:传统道德概念垂直空间隐喻存在心理现实性;道德概念和空间概念之间存在双向映射。     

特征和位置信息在价值驱动注意捕获中的作用

本研究采用训练−测试范式考察颜色和位置信息在价值驱动注意捕获中的作用。实验1考察是否存在基于具体位置的价值驱动的注意捕获效应。在训练阶段, 被试对8个位置中两个位置出现的红色目标反应伴随着高奖励反馈, 而对另外两个位置出现的红色目标反应伴随着低奖励反馈, 其它4个位置为中性位置, 没有目标出现。在测试阶段, 一半试次中红色刺激作为分心物出现。结果发现, 只有当分心刺激出现在高奖励位置和两个高奖励位置之间的中性位置时才能够捕获注意; 实验2考察颜色和位置信息在价值驱动注意捕获中的交互作用。在训练阶段, 将颜色特征和位置信息联合起来进行学习。在测试阶段, 和高、低奖励相联结的颜色刺激各在1/3试次中作为分心物出现。结果发现, 只有当高奖励颜色出现在高奖励位置或出现在高奖励位置之间的中性位置时才能够捕获注意。研究结果表明：(1)位置联结的价值驱动的注意捕获效应能够泛化到特定邻近位置上; (2)个体在训练阶段将颜色和位置的联合特征与奖励建立联结, 训练阶段建立的联结不能泛化到部分特征上。价值驱动注意捕获效应的泛化具有选择性。     

The role of visual spatial attention in adult developmental dyslexia

The present study investigated the nature of visual spatial attention deficits in adults with developmental dyslexia, using a partial report task with five-letter, digit, and symbol strings. Participants responded by a manual key press to one of nine alternatives, which included other characters in the string, allowing an assessment of position errors as well as intrusion errors. The results showed that the dyslexic adults performed significantly worse than age-matched controls with letter and digit strings but not with symbol strings. Both groups produced W-shaped serial position functions with letter and digit strings. The dyslexics' deficits with letter string stimuli were limited to position errors, specifically at the string-interior positions 2 and 4. These errors correlated with letter transposition reading errors (e.g., reading slat as “salt”), but not with the Rapid Automatized Naming (RAN) task. Overall, these results suggest that the dyslexic adults have a visual spatial attention deficit; however, the deficit does not reflect a reduced span in visual–spatial attention, but a deficit in processing a string of letters in parallel, probably due to difficulty in the coding of letter position.     

《易经》的宇宙观与阴阳五行家思想之渊源

若从思想自身的发展来看,阴阳五行家与《易经》有着重要的渊源关系。《易经》的阴阳变化观念和带有浓厚的原始思维特性的宇宙观,是阴阳五行家思想的理论基石,阴阳五行家的宇宙发生图式和序列便滥觞于此。《易经》的以“因果联想”为重要特征的认知方式对阴阳五行家认识和把握世界的基本方式产生了重要的影响。《易经》的时空观念也与阴阳五行家以阴阳五行配四时、四方,以阴阳五行说明宇宙之大化、社会之变迁、人事之行止的思想紧密联系在一起。     

Geographical profiling incorporating neighbourhood-level factors using spatial interaction modelling

The aim of this study was to examine the applicability of methods that use spatial interaction modelling to predict the most probable area for an offender's residence. Tokyo, which is the capital of Japan and is divided into 1507 square-kilometre zones, was selected as the study area. We analysed 4316 criminal trips to commit residential burglaries by 1089 offenders who lived in Tokyo. The following neighbourhood-level factors, and a distance-decay effect between zones, were incorporated into the proposed model: the size of the residential population aged 15–59 years in origin zones, the numbers of households living in detached houses, newcomers, the number of police facilities in destination zones, and the spatial structures of the criminal trips. Search areas calculated by the proposed model were smaller than previous models, suggesting that neighbourhood-level factors are important for predicting the location of an offender's residence.
