Toddler's memory and media-Picture book reading and watching video content are associated with memory at 2years of age.

Abstract

Memory develops across the course of the first years of life and is influenced by daily experiences, such as exposure to media like books and television. Memory as tapped by Deferred imitation (DI) requires that toddlers form a representation of the target actions that they can later use to reproduce the actions and in addition to measuring memory for real live events, it can also be used to measure memory for events viewed through media. Toddlers are frequently exposed to multiple forms of digital media in addition to more traditional forms of picture book reading. In a within-subjects design, memory was assessed with a DI task in 2-year-olds (n=89) using the Frankfurt Imitation Test. Deferred imitation was assessed after live and video demonstrations. Parents completed a survey about children's media use. Picture book reading for less than 30min a day predicted lower memory scores for actions demonstrated live. Watching video content for more than 1h a day predicted lower memory scores for actions demonstrated on video. Results are interpreted in terms of individual differences in experiences of traditional and digital media and the development of symbolic understanding.
