| 摘 要： | 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。

| Abstract: | By means of a divided visual field technique,this study has compared the RTs of graph pairs judgment in three kinds of visual field,and also discussed the lateralization characteristics of deaf and hearing individuals.The results show that:RTs in three kinds of visual field of deaf individuals are longer than those of hearing individuals,but marked differences between deaf and hearing individuals are not found;to deaf individuals,RT in bilateral visual field is the shortest one and RT in right visual field is the longest one,but marked difference among three kinds of visual field is not found;to hearing individuals,RT in right visual field is the shortest one,RT in left visual field is the longest one,it is also not found that marked differences among three kinds of visual field;RTs is three kinds of visual field of male are faster than those of female,but marked differences between male and female are not found. |
