Stop multitasking and just read: meta‐analyses of multitasking's effects on reading performance and reading time

Abstract

BackgroundMultitasking while reading is a commonplace activity. Many studies have been conducted examining the effect of multitasking on reading comprehension and times. The purpose of this meta‐analysis is to consolidate the empirical findings on reading comprehension and times in order to understand the overall effect of multitasking on reading. Characteristics of the reading situation, comprehension assessment and the secondary task were examined to determine if they varied the effect of multitasking.MethodsA systematic search of studies on multitasking and reading was conducted. Only studies that used random assignment and had participants reading independently were included. This screening yielded 22 independent studies (20 reports) that met inclusion criteria, with 20 studies on reading comprehension and 9 studies on reading times. Most of the studies involved adults reading expository texts.ResultsBased on robust variance estimation analyses, multitasking had a negative effect on reading comprehension (g = −0.28, p = .002). The effect was similar after outliers were removed (g = −0.26, p = .001). Based on moderator analyses, this negative effect may only occur when time was limited because the reading pace was controlled by the experimenter (g = −0.54, p < .001) as there was not a reliable effect when reading was self‐paced (g = −0.14, p = .10). Multitasking during reading lead to longer reading times (g = 0.52, p < .001).ConclusionsMultitasking during reading is detrimental to reading comprehension when time is limited. When readers control their own pace of reading, multitasking lengthens the time for the reading task. Therefore, multitasking while reading is less efficient than focusing attention on the primary task of reading.HighlightsWhat is already known about this topic Multitasking during reading is commonplace. Human cognitive resources are limited. Many studies exist on reading while multitasking. What this paper adds Overall effect for multitasking on reading comprehension is negative. Multitasking when reading time is limited is detrimental to comprehension. Multitasking has a greater negative effect when reading from paper than screens. Self‐paced reading times are longer when multitasking. Implications for theory, policy or practice Multitasking while reading is an inefficient practice. Students should be encouraged to focus on reading a text.
