    This study investigated the exposure to and use of screen devices in preschool children (3-5-years-old) and whether mobile media use related to executive functions, physical activity, and sleep. A total of 32 mothers from Southern Alberta completed online questionnaires that measured their child’s media exposure, mobile media use, executive function behaviors (e.g. attention, emotional control), physical activity, and sleep habits. Preschooler’s executive functioning was assessed with A Development Neuropsychological Assessment – Second Edition (NEPSY-II). Results indicated that children are meeting screen time recommendations set by the Canadian Pediatric Society (2017), spending an average of 34 minutes a day on any screen device. Television and mobile devices were the most commonly used. Children who used mobile media daily had significantly better ratings of emotional control compared to children who did not use mobile media daily. Sleep did not significantly moderate the relationship between mobile media use and executive functioning or physical activity outcomes. Interpretations of these findings, along with implications, limitations, and future directions are provided.
