A study from Northern Arizona University explored this exact question. Researchers worked with 26 parent-infant pairs. They observed them playing with three different sets of toys: electronic toys, traditional toys like wooden puzzles, and board books.
The results were interesting. The researchers noted that play with electronic toys was associated with less talk from parents. Parents spoke fewer words, took fewer turns in the conversation, and responded less to their child. When playing with traditional toys and books, the opposite was true. These sessions were linked to more parent talk and more back-and-forth interaction.
It is important to note this was a small study. It shows a link, not a direct cause. But its findings, published in a major medical journal, offer a useful way to think about playtime.
