摘　　要： 由于视觉经验的缺乏,盲人的空间认知存在一定的缺陷,尤其表现在对现实环境的空间布局认识存在困难。研究欲探究触觉地图技术辅助盲人建构表征的成效,并在此基础上探究盲人定向行走的效果。本研究是一个现场实验,采用能力配对的方式将被试随机分为三组,每组13人,两组接受触觉地图和言语描述干预,一组不接受任何处理,随后三组接受空间任务测试,测试不仅考察被试对环境空间布局的认识,而且还测量被试在现实环境的行走效率。结果发现,触觉地图组的被试不仅能够对环境形成较为精确的空间表征,而且还能借助表征在测验场地有效的行走,但触觉地图不能提升被试的行走速度,此外仍然有部分先天盲人不能借助触觉地图提升定向行走能力。 For lack of visual experience,visually-impaired persons show deficits in spatial cognition,especially in their cognition of the spatial layout of the real environment. The present study aims to explore the effectiveness of the spatial representation constructed with the aid of tactile maps,as well as the orientation and mobility of visually-impaired persons. The authors conducted a field test,where they randomly divided the partici pants into three groups,including the group with the task of feeling tactile maps,the group with the task of verbal description,and the control group. The results show the following： The group with the task of feeling tactile maps could show accurate spatial representation,and could,with its help,effectively walk in the experimental field,but the tactile maps could not speed up the pace of their walking,and a certain number of congenitally blind persons could not improve their ability in orientation and mobility with the aid of the tactile maps.
