Several methodological factors associated with the concurrent activities (finger-tapping) paradigm were considered in a cross-sectional study investigating cerebral patterns of asymmetry in three groups of English-speaking non-Hispanic dextral males at three levels of second language (Spanish) acquisition and one control group of monolinguals. Results revealed the fluent bilinguals to be bilateral and significantly different from other groups for native language tasks in English. Moreover, a priori contrasts indicate that greater right- than left-hand disruption in concurrent tapping may be typical of monolinguals, but can be influenced by other factors. Monolingual reliability test-retest correlations were .77 and .47.
在一项横断面研究中，研究人员考量了与同步活动（手指敲击）范式相关的几个方法学因素。该研究调查了三组处于三种第二语言（西班牙语）习得水平的非西班牙裔英语母语右利手男性以及一组单语者的大脑不对称模式。结果显示，流利的双语者在执行英语母语任务时呈现双侧性，且与其他组存在显著差异。此外，先验对比表明，在同步敲击任务中，单语者右手比左手受到的干扰更大可能是其典型特征，但也可能受其他因素影响。单语者的重测信度相关性分别为0.77和0.47。
