Abstract

Two groups of congenitally deaf and two groups of hearing right-handed subjects identified pairs of nonsense shapes and letters after simultaneous bilateral tactual exploration. In response to shapes, left and right hand pointing to multiple choice arrays were compared. Three response modes, writing and left and right and fingerspelling, were compared for letters. A tendency for right tactual field superiority for shapes was observed in all groups. Groups initially exposed to letters showed significant right field superiority across response modes for shapes. No left-right asymmetries were observed for letters. Differences due to deafness were not observed.

摘要

两组先天性失聪者和两组听力正常的右利手受试者在同时进行双侧触觉探索后，识别无意义形状和字母对。针对形状，比较左右手指向多项选择阵列的情况。针对字母，比较书写、左右手指拼写三种反应模式。在所有组中均观察到形状方面右触觉区域优势的趋势。最初接触字母的组在形状的所有反应模式中均表现出显著的右区域优势。对于字母未观察到左右不对称。未观察到因失聪导致的差异。
