DESCRIPTION (provided by applicant): The aim of this research is to investigate spatial learning and navigation within and across sensory modalities, between sighted, low vision and blind participant groups. The general hypothesis posits that spatial information learned from individual sensory modalities leads to the formation of a common spatial representation across modalities. Experiment I and II establish if some of the perceptual biases known for vision also manifest in tactile learning. This work represents the first effort to directly compare visual and tactile map learning and to investigate performance as a function of visual status. Experiment III uses a cross-modal learning paradigm to assess if functionally equivalent spatial representations are formed between learning with vision, touch, and spatial language. This is the first study of its kind to directly compare environmental learning with information matched environments across three sensory modalities. The final outcome of this research will significantly add to our understanding of spatial learning between the senses and speak to the extent of functional equivalence that exists across spatial representations. The results of these experiments will also benefit the development of navigation systems for the blind.

描述（由申请人提供）：这项研究的目的是研究在视觉，低视力和盲目参与者之间的感官方式内外的空间学习和导航。总体假设认为，从单个感觉方式中学到的空间信息导致形成跨模态的常见空间表示。实验I和II确定了一些因视力而闻名的感知偏见是否也表现在触觉学习中。这项工作代表了直接比较视觉和触觉图的学习并调查性能作为视觉状态的函数的第一个努力。实验III使用跨模式学习范式来评估在通过视觉，触摸和空间语言学习之间形成功能等效的空间表示。这是对直接将环境学习与三种感官方式匹配的环境进行比较的第一项研究。这项研究的最终结果将大大增加我们对感官之间空间学习的理解，并说明在空间表示之间存在的功能对等程度。这些实验的结果还将受益于盲人的导航系统的开发。
