This study was done to record the difference in habituation patterns of optically evoked blink reflexes in mentally retarded and normal adults. Sets of photic stimuli with fixed interstimulus duration were utilized in normal volunteers and mentally retarded adults. The interstimulus duration decreased with each sequential set. The blink responses were recorded on fibreoptic recording paper. These electrophysiological methods show objectively that the blink responses to light which habituate in normal adults fail to do so in those who are mentally retarded.
本研究旨在记录智障成年人与正常成年人在光诱发眨眼反射习惯化模式上的差异。在正常志愿者和智障成年人中使用了具有固定刺激间隔时间的一系列光刺激。刺激间隔时间随着每组序列的增加而减少。眨眼反应记录在光纤记录纸上。这些电生理方法客观地表明,正常成年人中对光产生习惯化的眨眼反应在智障成年人中并未出现。
