TY - JOUR AU - Beyens, Ine AB - BackgroundChildren are spending an increasing amount of time with mobile media, such as tablet computers and hand‐held video game players (Common Sense Media, ; Cristia & Seidl, ; Kabali et al., ). Many parents and educators are hopeful that these interactive forms of technology will benefit children (Christakis, ), although concern remains that the time devoted to these devices may displace opportunities for other forms of learning (Radesky, Schumacher, & Zuckerman, ).Thus far, scholars have not explored whether mobile device use is related to young children's effortful control (EC), a temperament‐based type of self‐regulation that is linked with a wide range of developmental outcomes. The current study explored the relation between the use of two forms of mobile media (tablets and hand‐held games) and EC among 3‐ to 5‐year‐olds. In addition, we aimed to identify individual differences in the relation between mobile media use and EC. Building on the findings from our prior work (Nathanson & Beyens, ), which uncovered a negative association between 3‐ to 5‐year‐olds’ tablet use and their sleep quality, we examined the role of sleep as a mediator and moderator of the relation between device use and EC.Tablets, hand‐held game players, and effortful controlTemperamental EC is TI - The role of sleep in the relation between young children's mobile media use and effortful control JO - British Journal of Developmental Psychology DO - 10.1111/bjdp.12196 DA - 2018-01-01 UR - https://www.deepdyve.com/lp/wiley/the-role-of-sleep-in-the-relation-between-young-children-s-mobile-tsQyQS3pNk SP - 1 EP - 21 VL - 36 IS - 1 DP - DeepDyve ER -
