【摘要】：选取3~5岁自闭症谱系障碍儿童(Autism Spectrum Disorder,ASD)与正常儿童各18名,采集其观看目标刺激沿不同垂直幅度、水平速度正弦曲线运动视频的眼动数据,考察振幅、速度等目标运动特征对被试平滑追踪眼动的影响。结果发现:(1)ASD儿童平滑追踪目标刺激的视觉位置误差显著大于正常儿童,其追踪目标的眼动轨迹不如正常组儿童平滑均匀,平滑追踪眼动存在明显不足。(2)正常儿童追踪目标刺激大振幅运行的位置误差显著大于小振幅运行条件,但ASD儿童却与之相反。(3)与正常儿童一样,目标刺激运行速度越快,ASD儿童平滑追踪的位置误差越大。总之,ASD儿童存在平滑追踪能力的不足;相比追踪大振幅运动的目标,ASD儿童追踪小振幅运动目标的能力更差。
[Abstract]:18 Autism Spectrum Disorders (ASD) and 18 normal children were selected from children with autism spectrum disorders aged 3 to 5 years old. The eye movement data of the target stimulus moving along different vertical amplitudes and horizontal velocities were collected and the amplitudes were investigated. Effects of velocity and other target motion characteristics on smooth tracking eye movement. The results showed that the visual position error of ASD was significantly higher than that of normal children, and the eye movement track of ASD was not as smooth and even as that of normal children. The position error of tracking target stimulation in normal children was significantly larger than that in small amplitude operation, but ASD was the opposite of that in normal children, and was the same as that in normal children, but there was no significant difference between ASD and normal children, but in ASD children the position error was significantly higher than that in children with small amplitude. The higher the speed of target stimulation, the greater the position error of smooth tracking in ASD children. In short, ASD children have the deficiency of smooth tracking ability, and their ability to track small amplitude moving targets is worse than that of large amplitude motion targets.
