本实验采用半视野速示法通过对聋人与听力正常人在三种视野条件下图形异同判断中选择反应时的比较 ,探讨了聋人与听力正常人大脑左右半球功能不对称性的特点。实验结果发现 :聋人在三种视野条件下的选择反应时都快于听力正常人 ,但差异均未在到显著性水平 ;聋人以双侧视野的平均反应时为最快 ,右视野的平均反应时最慢 ,听力正常人以右视野的平均反应时为最快 ,左视野的平均反应时最慢 ,但两类被试三种视野间的差异不显著 ;男性被试三种视野的选择反应时均快于女生被试相应视野的反应时 ,但性别间差异并不显著。
In this experiment, half-homotopic hysteroscopy was used to compare the functional response between deaf and normal hearing people in judging the similarities and differences of the images under the three visual field conditions. The functional asymmetry of the left and right hemispheres of the deaf and normal hearing people was discussed. The experimental results showed that deaf people responded faster than normal people under three visual field conditions, but the difference was not significant at the same time. Deaf people had the fastest average visual acuity The average response time is the slowest, the average hearing normal people with the right field of view the fastest average response, the left field of view the slowest average response time, but the three types of subjects were not significantly different between the three fields; When choosing reaction, the reaction time was faster than the corresponding field of view of the female students, but the difference between the sexes was not significant.
