摘要
采用眼动技术,比较正常儿童和学障儿童在不同眼跳任务中的眼跳差异,以对学障儿童尽早地进行鉴别。研究使用非文字材料,通过三个实验考察学障儿童和正常儿童的眼跳特征。在实验一中,通过反应性眼跳任务比较正常儿童和学障儿童的眼动指标。结果发现,学障儿童的反应性眼跳能力正常。实验二(反向眼跳任务)和实验三(记忆导向的眼跳任务)考察被试的自主控制眼跳的能力。结果表明,学障儿童的自主控制眼跳异常,发展迟滞。
This paper aims to compare the saccadic differences in different saccade tasks between normal children and children with learning disabilities（ LD） by adopting eye-movement technology,so as to identify the children with learning disabilities（ LD） early. The research was based on the non-text materials,three experiments were conducted to observe the saccades characteristics of normal children and those with learning disabilities. The first experiment was to make a comparison of the eye movement index of normal children and children with learning disabilities in reactive saccade task,which showed that the LD performed normally in reflexive saccades. Experiment II（ antisaccade task） and experiment III（ memory-guided saccade task） examined their ability of voluntary control of saccadic eye movements,the results indicated that the voluntary control of saccadic eye movements in learning disabilities were abnormal and delayed.
