本研究的目的是检验这一假设，即年龄的收购是一个显着的贡献者，在并发的口头手动任务条件下的偏侧效应，但有一个更大的样本（n = 102）比通常在这样的研究。在回顾了相关文献，并研究了几个严重的分析和方法的问题，已提出，涉及三组科目（母语人士，早期和晚期非母语人士）的实验结果。显着差异的偏侧效应之间的本地和晚期非本地组，从而产生的证据表明，在后期获得的第二语言的语音生产过程中增加右半球激活。
The object of the present study was to test the hypothesis that age of acquisition is a significant contributor to laterality effects under a concurrent verbal-manual task condition, but with a substantially larger sample (n = 102) than has been usual in such research. After reviewing the relevant literature and examining several serious analytical and methodological issues that have been raised, the results of an experiment involving three groups of subjects (native speakers, early and late non-native speakers) are presented. Significant differences in laterality effects were uncovered between the native and late non-native groups, thus producing evidence suggestive of increased right hemisphere activation during speech production in a late-acquired second language.
