In the present study we investigated the effects of concurrent verbal (reading) and nonverbal (humming) cognitive tasks on right- and left-hand finger-tapping in relation to hemispheric asymmetry in right- and left-handed females and males. The aim of the study was to investigate effects of attending either to the cognitive or manual task, and effects of differences in arousal attributed to the various tasks. The results revealed decreased finger-tapping frequency in males, and especially in right-handers, during execution of both the reading and humming task. For the reading task, the interference was lateralized, with a greater decrease in tapping frequency in the right hand. No interference was observed in the female groups. Biased attention to the cognitive or manual task did not have any effect on finger-tapping. However, increased arousal was observed during execution of the humming task, thus indicating this to be a mediating factor in finger-tapping interference.
在本研究中，我们调查了同时进行的言语（阅读）和非言语（哼唱）认知任务对右利手和左利手女性及男性左右手指敲击的影响，这些影响与半球不对称有关。本研究的目的是调查专注于认知任务或手动任务的影响，以及归因于各种任务的唤醒差异的影响。结果显示，在执行阅读和哼唱任务期间，男性尤其是右利手的手指敲击频率降低。对于阅读任务，干扰是单侧化的，右手的敲击频率下降幅度更大。在女性组中未观察到干扰。对认知任务或手动任务的偏向性关注对手指敲击没有任何影响。然而，在哼唱任务执行期间观察到唤醒增加，因此表明这是手指敲击干扰的一个中介因素。
