This paper presents an experiment with human subjects concerning the vague spatial relation ‘near ’ in environmental space. After the topic is introduced and relevant previous work surveyed, the experiment is described. Three approaches to experimental analysis are presented and discussed: nearness neighbourhoods as regions with broad boundaries, fuzzy nearness and distance measures, and four-valued logic. Issues discussed in further detail are the truth gap – truth glut hypotheses regarding the psychology of vague predi-cates, and formal properties of the three-valued nearness relation. Conclusions are drawn and directions for future work suggested. 1
