Abstract. This article first situates media multitasking in the changing media ecology. Then, grounded in concepts of stress and flow, limited capacity, and threaded cognition, it develops a four-dimensional theory of media multitasking intensity. Based on the key aspects of media multitasking intensity, the subsequent section proposes two primary influences (executive functioning and self-regulation) and one primary outcome (general stress). An application example focuses on several media multitasking issues and the stress outcome for adolescents within their family environment. The final section suggests a few key methodological implications for studying the theory of media multitasking intensity (self-report, and both temporal and social contexts). The theory of media multitasking intensity generates insights about the functional (i.e., valuable) variation within experiences of media as they overlap with and interrupt experiences of the physical and mediated world.

媒体多任务强度理论

摘要。本文首先将媒体多任务定位在不断变化的媒体生态中。然后，基于压力和流动、有限容量和线程认知的概念，它发展了媒体多任务强度的四维理论。基于媒体多任务处理强度的关键方面，下一节提出了两个主要影响（执行功能和自我调节）和一个主要结果（一般压力）。一个应用示例侧重于几个媒体多任务处理问题以及青少年在家庭环境中的压力结果。最后一部分提出了研究媒体多任务强度理论（自我报告，以及时间和社会背景）的一些关键方法论意义。媒体多任务强度理论产生了关于功能（即，
