基于眼动的孤独症儿童看图说话能力研究

A Study on the Ability of Autistic Children to Read Pictures and Speak Based on Eye-movement

目的了解孤独症儿童看图说话能力的现状及其相关因素,为提高孤独症儿童看图说话能力提供参考建议。方法采用tobii二代眼镜式眼动仪对40名7~13岁孤独症儿童的看图说话能力进行实验。结果平均年龄10岁的孤独症儿童具有看图说话能力占60%,但语句不完整、词类少、概括不到位;无人物关系、单幅图的看图说话能力比有人物关系、多幅图的看图说话能力相对较好(P<0.05);注视点低的图片看图说话得分显著高于注视点高的得分(P<0.05);突出关键信息的热点区域注视点个数与看图说话得分无关。结论孤独症儿童看图说话能力较弱且具有特殊性,表达和理解均存在问题,需要有针对性地干预。
