Eye movements latencies toward peripherally presented stimuli were measured in 10-year-old dyslexic and control children. Dyslexic subjects, previously found to be oversensitive to stimulation of the magnocellular channel, showed reduced latencies as compared to normally reading controls. An attention shifting task was also used which showed no group differences in latencies of eye movements. The data are discussed in terms of the hypothesis of magnocellular system alteration and attention dysfunction in dyslexia. Additionally, sex differences in eye movement latencies were found and are discussed.
对10岁的诵读困难儿童和对照儿童测量了其对周边呈现刺激的眼动潜伏期。先前发现诵读困难受试者对大细胞通道刺激过度敏感，与正常阅读的对照组相比，其潜伏期缩短。还使用了一项注意力转移任务，结果显示两组在眼动潜伏期方面没有差异。根据诵读困难中存在大细胞系统改变和注意力功能障碍的假设对数据进行了讨论。此外，还发现并讨论了眼动潜伏期的性别差异。
