A previous study [1] demonstrated that when subject and experimental variables are controlled, similar levels of left hemisphere language lateralization are obtained in bilinguals and monolinguals. The present study used the same group of bilinguals (adult, late acquirers of their second language) in an auditory lateralization task. A similar degree of left hemisphere asymmetry was again obtained for the bilinguals' two languages and for the monolinguals. Furthermore, the individual performances of the bilinguals--within the present task and across visual and auditory tasks--paralleled those of monolinguals. Thus, converging evidence is provided for equal levels of left hemisphere language dominance in bilinguals and monolinguals.
先前的一项研究[1]表明，当控制主体和实验变量时，双语者和单语者的左半球语言侧化水平相似。本研究在一项听觉侧化任务中使用了同一组双语者（成年，第二语言的晚期习得者）。双语者的两种语言和单语者再次获得了相似程度的左半球不对称性。此外，双语者在当前任务中以及跨视觉和听觉任务的个体表现与单语者相当。因此，为双语者和单语者左半球语言优势水平相等提供了趋同的证据。
