Despite the recent proliferation of research on media multitasking, a comprehensive meta-analytic review of its effects has not been available. Based on a review of 49 media multitasking studies, this meta-analysis showed that multitasking has negative effects on cognitive outcomes, whereas it has positive effects on attitudinal (or persuasion-related) outcomes. Moderator analyses suggested that the negative effects of multitasking on cognitive outcomes varied by (a) user control, (b) task relevance, and (c) task contiguity. Specifically, multitasking had greater effects (a) when media users had less control over the media, (b) for tasks that were unrelated, and (c) for tasks that were physically distant. Implications for future multitasking research are further discussed.

媒体多任务对认知和态度结果的影响：一项荟萃分析

尽管最近有关媒体多任务处理的研究激增，但尚未对其效果进行全面的荟萃分析。基于对49项媒体多任务研究的回顾，该荟萃分析表明，多任务对认知结果具有负面影响，而对态度（或与说服相关的）结果具有正面影响。主持人的分析表明，多任务处理对认知结果的负面影响因（a）用户控制，（b）任务相关性和（c）任务连续性而异。具体而言，多任务处理具有更大的影响（a）当媒体用户对媒体的控制较少时；（b）对于不相关的任务；以及（c）对于物理上遥远的任务。进一步讨论了对未来多任务研究的意义。
