摘 要: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。To investigate the behavioural performance of visual attention habituation in normal infants, 538 infants aged 0-3 years were exposed to a redundant visual stimulus repeated 6 times and a novel one at a 10-second intervals. A set of electronic control and simultaneous camcorder system was employed to record the infants' fixation time to each stimulus, and both of response decrement and response recovery were then calculated. The results showed that all infants 'fixation time decreased gradually with the increase of repeated stimuli, but recovered soon for the novel stimulus. Younger infants usually stared the stimulus with a longer time comparing to older infants, and both of response decrement and response recovery increased with infants' growing. It is concluded that the test of visual attention habituation is valuable for the assessment of cerebral function in infants.
