为了解正常婴幼儿视觉注意习惯化的行为表现,应用电子控制装置和同步摄像系统,观察、记录正常婴幼儿对6次重复视觉图像信号刺激和1次新鲜图像信号刺激的注视时间,并计算应答降低率和应答恢复值。结果:538例2个月～36个月正常婴幼儿对重复刺激的注视时间随刺激次数逐渐下降,对新鲜刺激表现出注视时间的恢复;婴幼儿对同一刺激的应答降低率随年龄而增高,应答恢复率也随年龄而增加。结果表明,视觉注意习惯化测验对了解婴幼儿的脑功能发育有较好的应用前景。
In order to understand the normal infants’ visual attention to the habitual behavior, the electronic control device and synchronous camera system were used to observe and record the gaze time of normal infants and young children on six repetitive visual image signals and one fresh image signal stimulus, and calculate the response Reduction rate and response recovery value. Results: 538 cases of 2 months to 36 months of normal infants with repeated stimulation of the fixation time decreased with the number of stimuli, showing fresh stimulation of fixation time recovery; infants and young children on the same stimulus response rate decreased with age, Response recovery rate also increases with age. The results show that visual attention to the habitual test to understand the development of brain function in infants and young children have a better prospect.
