A 2015 U.S. study which looked at the effects of different toys on children’s learning found that traditional toys, including books, were more effective in increasing the quantity and quality of language than modern electronic toys.
The small-scale study looked at 26 children aged 10 to 16 months, and found that along with traditional toys, such as wooden puzzles and shape-sorters, reading encouraged “a rich communicative interaction between parents and infants,” with parents talking more and using more vocabulary associated with themes in the book than when playing.
