VISUAL GUIDANCE AND IMAGERY IN TACTUAL PERCEPTION AND BRAILLE

这项研究计划将评估视觉体验对 视力正常、晚期失明和先天性失明的人的触觉感知。 视觉意象和视觉空间参考框架被认为是 对视力正常的人和盲人的触觉很重要。 研究 触觉感知的能力，在晚期失明，一个高度熟练的人口， 也可能揭示触觉的潜力。 人们常 假设缺乏视觉体验可能解释了较低的性能 在某些空间任务中的表现。 有远见的人，早， 晚盲将在一些任务中进行比较，包括触觉 图片、有形地图、触觉错觉和盲文识别。 的 触觉地图的研究是一项新的重大举措。 一个新系列的 研究将调查神经系统疾病患者的触觉感知 损伤，尤其是顶叶损伤。 视觉和盲人的触觉感知研究将集中在 改善触觉性能的方法。 实验将 强调研究最佳触摸位置，视觉引导， 偏侧效应和注意力因素。 建议进行一项关于 照明水平对触觉注意的影响。 其他实验 将研究记忆和保持对触觉空间的影响， 认知，因为视觉模态可能在回忆中提供优势。 的 研究对低血压患者的康复至关重要。 视觉和光感。 触觉地图的研究是 这对改善盲人的行动能力很重要。

The research program will assess the influence of visual experience on tactile perception in sighted, late blind, and congenitally blind people. Visual imagery and visual spatial frames of reference are thought to be important for tactual perception in sighted and blind people. The study of tactile perception in the late blind, a highly skilled population, also may reveal the potential of the sense of touch. It has often been assumed that the lack of visual experience may explain lower performance of the congenitally blind in some spatial tasks. The sighted, early, and late blind will be compared in a number of tasks, including tactile pictures, tangible maps, tactile illusions, and braille recognition. The study of tactile maps represents a major, new initiative. A new line of research will investigate haptic perception in subjects with neurological impairment, especially parietal lesions. Research on tactile perception in the sighted and blind will focus on methods for the improvement of tactile performance. Experiments will stress the investigation of optimal touching positions, visual guidance, laterality effects, and attentional factors. A study is proposed on the effect of illumination level on tactile attention. Other experiments will examine the influence of memory and retention on tactile spatial cognition, since the visual modality may offer advantages in recall. The research is of importance for the rehabilitation of people with low vision and those with light perception. The study of tactile maps is important for the improvement of mobility in the blind.
