项目摘要

The purpose of this study is to investigate the visual information processing strategies of inherently profound hearing-impaired children who have a higher reading ability than other hearing-impaired children by measuring their eye movements in reading visual materials. Next, their cognitive production, as like comprehension on visual materials was compared to that production with the same age of normal hearing. Takei Scientific Instrument (Free View Type Talk Eye □) were used to measure eye-movements which included processing time, number of fixation, fixation time, regression movements, cognitive span and the rate of comprehension in visual materials.In 2004 research, word problem was utilized as research material to measure reference strategy. The results indicated that hearing-impaired children with higher reading ability used more reference visual material, more frequent fixation and regression, and shorter referring time and span than normal hearing children..In 2005 research, co … More ding strategy of two visually imagery information were utilized. The result indicated that hearing-impaired children frequently used a visual coding processing strategy with higher number of fixations, a shorter fixation time, and they also utilize semantic categorize in coding as like that of children with normal hearing.In 2006, the research examined the relationship between the degree of fixation location and the development of story situation of hearing ability in reading comprehension of hearing-impaired children. As a result, children with hearing impairment had more fixations in development and conclusion and this tendency increase in higher grade. Moreover, children with hearing impaired children who have the same reading ability were long fixation time in specific scene in story.These findings revealed that hearing-impaired children with higher reading ability have same developmental tendency but they have some different using and strategies to processing visual imagery information.

本研究的目的是通过测量阅读视觉材料时的眼动，探讨阅读能力高于其他听障儿童的先天性深度听障儿童的视觉信息加工策略。其次，他们的认知生产，如对视觉材料的理解，比较与正常听力相同年龄的生产。本研究采用Takei Scientific Instrument（Free View Type Talk Eye □）测量被试的眼动，包括加工时间、注视次数、注视时间、回退运动、认知广度和视觉材料的理解率。结果表明，与听力正常儿童相比，阅读能力较强的听障儿童使用更多的参考视觉材料，注视和回视的频率较高，参考时间和参考广度较短。在2005年的研究中， ...更多信息采用两种视觉图像信息的匹配策略。结果表明，听力障碍儿童与听力正常儿童一样，经常使用注视次数较多、注视时间较短的视觉编码加工策略，并利用语义分类进行编码。本研究探讨了在阅读理解过程中，注视位置与听觉能力故事情境发展的关系。残疾儿童结果表明，听障儿童在发展和结论上有更多的注视，且这种倾向随着年级的升高而增加。另外，具有相同阅读能力的听障儿童对故事中特定场景的注视时间较长，这说明具有较高阅读能力的听障儿童在加工视觉表象信息时具有相同的发展趋势，但在加工视觉表象信息时存在一定的差异。少
