项目摘要

The purpose of this research is to reveal structure of representation of environment on assumption of that human cognitive map is corresponding with components of image of city as Lynch proposed. We investigated effects of pre-presented information on cognitive map by psychophysical methods. We also investigated structure of cognitive map which is acquired by exploration of virtual environment that simulates real urban environment by psychophysical experiments and by measurement of magnetoencephalography.1.We investigated effects of path and node information that is aurally presented before wayfinding in virtual environment on time of wayfinding. When structure of environment is complex and there is no landmark, exocentric path/node information is more effective than egocentric path/node information. It is suggested that exocentric information is more effective for acquisition of cognitive map.2.We investigated effects of path and landmark information that is presented as a map before wayfinding in virtual environment on time of wayfinding. We found that when there was false information about path or landmark on the map, time of wayfinding became longer. Specially, when there was false information about landmark, the effect spread more than neighborhood of the landmark. It is suggested that mismatch of landmark between environment and map disturb acquisition of cognitive map.3.We investigated effects of landmark information and district information on acquisition of cognitive map by psychophysical and cognitive-neuroscientific methods. It was revealed that depending of lack of landmark or district information, structure of cognitive map and neural substrate are significantly different.4.We are going to propose method to solve "lost-child problem" in city environment and media environment through revealing neural network for acquisition of cognitive map.

本研究的目的是在人类认知地图与林奇提出的城市形象组成部分相对应的假设下，揭示环境表征的结构。我们通过心理物理学方法研究了预先呈现的信息对认知图的影响。我们还研究了认知地图的结构，该认知地图是通过心理物理实验和脑磁图测量来探索模拟真实城市环境的虚拟环境而获得的。1.我们研究了虚拟环境中寻路前听觉呈现的路径和节点信息对寻路时间的影响。当环境结构复杂且没有路标时，外心路径/节点信息比自心路径/节点信息更有效。表明外心信息对于认知地图的获取更为有效。2.我们研究了在虚拟环境中寻路之前呈现为地图的路径和地标信息对寻路时间的影响。我们发现，当地图上存在有关路径或地标的错误信息时，寻路时间会变长。特别是，当存在有关地标的虚假信息时，影响的传播范围比地标的邻域更大。这表明环境与地图之间的地标不匹配会干扰认知地图的获取。3.我们通过心理物理学和认知神经科学的方法研究了地标信息和区域信息对认知地图获取的影响。结果表明，由于地标或地区信息的缺乏，认知图的结构和神经基质显着不同。4.我们将提出通过揭示用于获取认知图的神经网络来解决城市环境和媒体环境中的“走失儿童问题”的方法。
