Executive attention modulates the facilitating effect of electronic storybooks on information encoding in preschoolers

Abstract

Interactive features and multimedia elements in electronic storybooks might enhance knowledge acquisition in children due to the playful learning experience they provide. However, to date, there is no systematic research on the long-term efficacy of storybooks, and the individual cognitive factors that influence information processing when using these apps. Therefore, in Experiment 1, we focused on long-term improvements. Children (M = 5.55 years, SD = 0.51, N = 33) were divided into an Interactive App group (N = 16) and a Print Book group (N = 17), then they were exposed to a story. Their recall performance was measured immediately after the exposure and three weeks later. In Experiment 2, we focused on individual differences in cognitive factors (working memory and sustained attention). Children (M = 5.56 years, SD = 0.62, N = 32) were exposed to three stories with interactive, multimedia-only elements and an audio-only condition. Caregivers were asked to fill out the ADHD Rating Scale-IV regarding each child. According to our results, in Experiment 1, children in the Interactive App group performed better compared to the Print Book group and this improvement persisted over time. In Experiment 2, we replicated the results of Experiment 1, however, children with poorer sustained attentional abilities performed worse in multimedia and interactive conditions compared to the audio-only condition. Our results indicate that electronic storybooks can facilitate learning because they enhance encoding efficacy. However, the benefit is only evident in children with good attentional control abilities. Our results guide parents and educators on how to choose and design age-appropriate applications for learning.
