Abstract

With recent developments in technology, media multitasking is an ever-increasing phenomenon. Although most studies associate media multitasking with high impulsivity and poorer cognitive performance, findings in the literature have been mixed, with some studies suggesting the opposite. The aim of this study was to investigate the relationship between media multitasking and the capacity to exert inhibitory control, as well as the ability to multitask in a multisensory setting. Results showed that media multitasking was associated with high attentional impulsivity and lower initiatory self-control, but not with inhibitory self-control. Relatedly, heavy media multitaskers were slower and showed more omission errors on the go/no-go task, suggestive of inattention; however, they were better at inhibiting already initiated motoric responses in the stop signal task. Media multitasking was further associated with faster responses when a letter and a tone task were temporally separated, but not when they were presented closer in time. Taken together, the results suggest a more nuanced relationship between media multitasking, personality and cognitive ability than has previously been thought. This has important real life implications for media multitasking, showing both advantages and disadvantages.

媒体多任务处理、冲动和双重任务能力

随着技术的发展，媒体多任务处理是一种日益增长的现象。尽管大多数研究将媒体多任务处理与高冲动性和较差的认知表现联系在一起，但文献中的发现喜忧参半，一些研究表明情况恰恰相反。本研究的目的是调查媒体多任务处理与施加抑制性控制的能力以及在多感官环境中多任务处理的能力之间的关系。结果表明，媒体多任务处理与高注意力冲动和低启动自我控制有关，但与抑制性自我控制无关。与此相关的是，重度媒体多任务处理者在进行/不进行任务时速度较慢，表现出更多的遗漏错误，这表明他们注意力不集中；然而，他们在停止信号任务中更善于抑制已经启动的运动反应。当字母和音调任务在时间上分开时，媒体多任务处理与更快的反应进一步相关，但当它们在时间上更接近时则没有。总之，研究结果表明，媒体多任务处理、个性和认知能力之间的关系比以前想象的更为微妙。这对媒体多任务处理有着重要的现实意义，既有优点也有缺点。
