视觉剥夺可能会导致其他感觉方式的表现增强。在触觉模态中是否是这种情况是有争议的，可能取决于具体的训练和经验。我们比较了正常人被蒙眼五天的盲文字符识别任务的正常受试者的表现。每组中的一些参与者（蒙眼和有视力）接受了强化盲文培训，以抵消经验的影响。无论触觉训练如何，蒙眼受试者在盲文辨别任务中的表现都优于有视力的受试者。对于左手食指，在正式的盲文课程中没有使用过，蒙眼对表现没有影响，而接受触觉训练的受试者表现优于未受刺激的受试者。这些结果表明，视觉剥夺加快盲文学习，并可能与行为相关的神经可塑性变化。神经报告13：571-574（C）2002 Lippincott威廉姆斯威尔金斯。
Visual deprivation may lead to enhanced performance in other sensory modalities. Whether this is the case in the tactile modality is controversial and may depend upon specific training and experience. We compared the performance of sighted subjects on a Braille character discrimination task to that of normal individuals blindfolded for a period of five days. Some participants in each group (blindfolded and sighted) received intensive Braille training to offset the effects of experience. Blindfolded subjects performed better than sighted subjects in the Braille discrimination task, irrespective of tactile training. For the left index finger, which had not been used in the formal Braille classes, blindfolding had no effect on performance while subjects who underwent tactile training outperformed non-stimulated participants. These results suggest that visual deprivation speeds up Braille learning and may be associated with behaviorally relevant neuroplastic changes.
