READING IN PERIPHERAL VISION

描述(改编自申请人的摘要)：这是一笔直接的赠款 低视力患者的阅读问题。具体来说，PI是 对那些黄斑损伤需要阅读的病例感兴趣 外周视网膜。在这样的条件下，阅读是困难的。建议 研究将调查关于这一困难原因的三种假设： 在外围国家，聚集/拥挤效应的破坏性更大。因此，瞄准 1寻求将这些影响降至最低。相位的外围表示为 不准确。目标2将试图通过最大限度地减少需求来提高阅读速度 以获取阶段信息。患者缺乏对周边阅读的练习。目标3 将考察广泛练习外围阅读的效果。 实验将在视力正常的受试者身上进行，也将在 有中枢暗点的受试者。

DESCRIPTION (Adapted From The Applicant's Abstract): This is a grant directed at the problem of reading in low vision patients. Specifically, the PI is interested in those cases where macular damage makes it necessary to read with peripheral retina. Reading is difficult under such conditions. Proposed research will investigate three hypotheses about the causes of that difficulty: Grouping/crowding effects are more damaging in the periphery. Consequently, Aim 1 seeks to minimize these effects. Peripheral representation of phase is inaccurate. Aim 2 will attempt to enhance reading speed by minimizing the need for phase information. Patients lack of practice with peripheral reading. Aim 3 will examine the effects of extensive practice with peripheral reading. Experiments will be carried out with normally-sighted subjects as well as with subjects having central scotomata.
