Media multitasking is the concurrent use of multiple digital media streams. Media multitasking has been associated with depressive symptoms and social anxiety by a study involving 318 participants.[1] A 2018 review found that while the literature is sparse and inconclusive, people who do a heavy amount of media multitasking have worse performance in several cognitive domains.[2][3] One of the authors commented that while the data does not "unambiguously show that media multitasking causes a change in attention and memory," media multitasking is an inefficient practice that requires "task switching" costs including "limitations in auditory and visual processing".[4][5][6]
In many cases, media multitasking is made up of experiences that are not necessarily intended to be combined or coordinated. For example, a user may be browsing the Web, listening to music, playing video games, using e-mail, and/or talking on the phone while watching TV.[7] More intentionally coordinated forms of media multitasking are emerging in the form of "co-active media" and particularly "co-active TV".
