This research explored ways gifted children with learning disabilities perceive and recall auditory and visual input and apply this information to reading, mathematics, and spelling. 24 learning-disabled/gifted children and a matched control group of normally achieving gifted students were tested for oral reading, word recognition and analysis, listening comprehension, and spelling. In mathematics, they were tested for numeration, mental and written computation, word problems, and numerical reasoning. To explore perception and memory skills, students were administered formal tests of visual and auditory memory as well as auditory discrimination of sounds. Their responses to reading and to mathematical computations were further considered for evidence of problems in visual discrimination, visual sequencing, and visual spatial areas. Analyses indicated that these learning-disabled/gifted students were significantly weaker than controls in their decoding skills, in spelling, and in most areas of mathematics. They were also significantly weaker in auditory discrimination and memory, and in visual discrimination, sequencing, and spatial abilities. Conclusions are that these underlying perceptual and memory deficits may be related to students' academic problems.
本研究探索了有学习障碍的天才儿童感知和回忆听觉及视觉输入,并将这些信息应用于阅读、数学和拼写的方式。对24名有学习障碍的天才儿童和一组与之匹配的成绩正常的天才学生对照组进行了朗读、单词识别与分析、听力理解和拼写测试。在数学方面,对他们进行了计数、心算和笔算、应用题及数字推理测试。为了探究感知和记忆技能,对学生进行了视觉和听觉记忆以及声音听觉辨别方面的正式测试。还进一步考量了他们在阅读和数学计算方面的反应,以寻找视觉辨别、视觉排序和视觉空间领域存在问题的证据。分析表明,这些有学习障碍的天才学生在解码技能、拼写以及大多数数学领域明显比对照组差。他们在听觉辨别和记忆、视觉辨别、排序及空间能力方面也明显较弱。结论是,这些潜在的感知和记忆缺陷可能与学生的学业问题有关。
