采用事件相关电位(ERP)探索问题解决过程中顿悟的神经机制。以猜谜作业为实验程序,对“有顿悟”和“无顿悟”答案引发的脑电分别进行叠加和平均,并将二者相减（有顿悟-无顿悟）得到差异波。在250~500 ms “有顿悟”比“无顿悟”的ERP波形有一个更加负性的偏移,在差异波中,这个负成分的潜伏期约为380 ms（N380）。地形图和电流密度图显示,N380在额中央区活动最强。偶极子源定位分析结果显示,N380可能起源于扣带前回。因此,N380可能反映顿悟问题解决过程中思维定势的突破。 相似文献

大量的神经生理学实验久已证实由刺激引起的外周神经生理效应具有类似于心理物理效应的高度压缩现象。从外周神经纤维中观察到的神经脉冲频率或发生电位是描述这种压缩效应的常用方法。半个多世纪以来一部分研究人员观察到压缩效应遵守刺激强度的线性对数函数,而另一部分研究人员则观察到幂函数。这种传统实验分歧,通过笔者前时建立的刺激一效应方程,得到合理的说明和两者的统一 相似文献

Eysenck's Psychoticism, Extraversion and Neuroticism (PEN) Inventory was used to explore the role of personality variables in augmented personal space required by assaultive offenders. For both violent (n = 20) and nonviolent (n = 20) subjects personal space was greatest from a rear approach. Neither personality scores nor nature of offense alone predicted personal space needs; however personal space was significantly elevated in all directions for assaultive offenders with high scores on the psychoticism scale of the PEN Inventory. 相似文献

At its core, the evolution of democratic civil society is a process of transcending existing, historical social space, a process that desires to dissolve “political society” into “civil society” and with it to reformulate space as more democratic, participatory public space, and global spheres of interaction. In this article, the author examines the implications of globalization and the evolution of democratic civil society. Drawing on the work of French theorists de Certeau and Lefebvre, the author examines the nature of space as a social construct and the importance of understanding space as a practiced place in relation to the evolution of democratic civil society that makes transnational space a practiced place for global civil society. The author argues that as globalization spreads across nation-states, spatial forces produced by economic, cultural, and political discourses and practices give way to the potential for the evolution of democratic civil society. 相似文献

Interpersonal distance plays an important role in human social interaction. With the increasing usage of virtual reality in social interaction, people's interpersonal distance in virtual space attracts great attention. It remains unclear whether and to what extent human-required interpersonal distance is altered by crowded virtual scenes. In this study, we manipulated crowd density in virtual environments and used the classical stop-distance paradigm to measure required interpersonal distances at different crowd densities. We found that people's required interpersonal distance decreased with increased social crowdedness but not with physical crowdedness. Moreover, the decrease of two types of interpersonal distance was associated with the globally averaged crowd density rather than local crowd density. The reduction is not due to the imitation of other virtual humans in the crowd. Moreover, we developed a model to describe the quantitative relationships between the crowdedness of the environment and the required interpersonal distance. Our finding provides insights into designing user-friendly virtual humans in metaverse virtual worlds. 相似文献

The task‐irrelevant spatial location of a cue stimulus affects the processing of a subsequent target. This “Posner effect” has been explained by an exogenous attention shift to the spatial location of the cue, improving perceptual processing of the target. We studied whether the left/right location of task‐irrelevant and uninformative tones produces cueing effects on the processing of visual targets. Tones were presented randomly from left or right. In the first condition, the subsequent visual target, requiring response either with the left or right hand, was presented peripherally to left or right. In the second condition, the target was a centrally presented left/right‐pointing arrow, indicating the response hand. In the third condition, the tone and the central arrow were presented simultaneously. Data were recorded on compatible (the tone location and the response hand were the same) and incompatible trials. Reaction times were longer on incompatible than on compatible trials. The results of the second and third conditions are difficult to explain with the attention‐shift model emphasizing improved perceptual processing in the cued location, as the central target did not require any location‐based processing. Consequently, as an alternative explanation they suggest response priming in the hand corresponding to the spatial location of the tone. Simultaneous lateralized readiness potential (LRP) recordings were consistent with the behavioral data, the tone cues eliciting on incompatible trials a fast preparation for the incorrect response and on compatible trials preparation for the correct response. 相似文献

The Test for Creative Thinking—Drawing Production (TCT‐DP) is designed as an effective drawing‐based instrument for measuring creative potential. Many studies report adaptation efforts in other cultures pointing out good psychometric properties of the instrument nonetheless revealing also some trouble spots. The present study includes adaptation of TCT‐DP in Latvia and investigation of psychometric properties of the instrument such as measurement invariance between forms, sequence effect, gender differences, and factor structure of criteria employing methodology of structural equation modeling. Two samples were involved in the study—9th‐grade students (n = 300) and 15‐year‐old 9th‐grade students (n = 200). Results indicate that trained judges are able to achieve high reliability in evaluation of TCT‐DP total score and all criteria if some criteria are divided into subcategories. It was also found that TCT‐DP has measurement invariance between both forms but has small effect sizes regarding gender differences and method sequence. Observed differences of TCT‐DP total scores between the Latvian sample and relevant samples from Germany and Hong Kong could be considered as trivial. The study also revealed that, following original instructions, some test criteria had strong interdependence and therefore strategies in the evaluation process reducing interdependencies between criteria should be considered in future studies on the structure of TCT‐DP. 相似文献

Young separated refugees are exiled from familiar places and on seeking asylum encounter new, potentially alienating, places. Yet, there is limited research regarding the effects of location on the psychological experiences of young separated refugees. This study explores the relationships that young adults who arrived in the UK as separated refugees have with the spaces that they inhabit and the consequences of these. It draws on qualitative interviews with young men from Iraq and Afghanistan who are living in London. Four key themes emerged from the analysis. Participants felt frustrated in bureaucratic settings where processes of labelling and physical manipulation prevented their sense of subjectivity from being expressed. Certain community spaces offered a rich range of support. Micro‐spaces of belonging and embodied processes of exploration in the wider community were also reported to be psychologically beneficial. The themes suggest that considerations of young separated refugees' relations to place may provide alternative psychological understandings of their experiences, particularly in relation to concepts such as trauma. Policy implications related to immigration control and the benefits of community projects are highlighted. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

An increase in brain activity known as the “readiness potential” (RP) can be seen over central scalp locations in the seconds leading up to a volitionally timed movement. This activity precedes awareness of the ensuing movement by as much as two seconds and has been hypothesized to reflect preconscious planning and/or preparation of the movement. Using a novel experimental design, we teased apart the relative contribution of motor-related and non-motor-related processes to the RP. The results of our experiment reveal that robust RPs occured in the absence of movement and that motor-related processes did not significantly modulate the RP. This suggests that the RP measured here is unlikely to reflect preconscious motor planning or preparation of an ensuing movement, and instead may reflect decision-related or anticipatory processes that are non-motoric in nature. 相似文献

This paper describes the development and implementation of qualitative behavioural criteria in order to analyse the conduct of pedestrians and vehicles when they are required to interact with each other, with particular interest to street designs with elements of shared space. The new behavioural analysis technique is developed by identifying the fundamental principles that underpin existing traffic analyses, such as traffic conflicts techniques, and adapting those to a qualitative framework that describes the mindset and rationale of road users. The technique is then applied to a case study in London, using video data from periods before and after the redevelopment of the Exhibition Road site from a conventional dual carriageway to a modern design with some elements of shared space. With the main goals being to assess the pedestrians’ confidence and the vehicles’ tolerance/patience when forced to interact with each other, behavioural trends are related to instantaneous characteristics of the vehicle flow (vehicle approach speed and traffic density). The data produced are used to develop and validate qualitative behavioural relationships for pedestrian–vehicle interactions, as well as location-specific conclusions for the Exhibition Road site. 相似文献
