Abstract

The role of the right hemisphere in a task of haptic discrimination of line orientation was studied in 16 children aged 7.6 and 16 adults aged 25 yr. The exploratory movements were limited to hand and wrist, since it has been shown that distal movements are mediated by the contralateral hemisphere. A comparison of the performance of the two hands shows a clear superiority of the left hand and inferred right hemisphere in both children and adults. An special emphasis in the discussion is given to the role of the experimental procedure in enhancing the effect of the hemispheric functional asymmetries.

摘要

对16名7.6岁的儿童和16名25岁的成年人，研究了右半球在触觉辨别线条方向任务中的作用。探索性动作仅限于手部和腕部，因为已有研究表明，远端动作由对侧半球介导。对双手表现的比较显示，在儿童和成年人中，左手以及推断出的右半球都具有明显优势。讨论中特别强调了实验程序在增强半球功能不对称效应方面的作用。
