In a New York Times article, studies claim that children who are exposed to more screens at a younger age have fewer conversations with their parents/guardians. They measured this study based on 3 various ways of language: words spoken by an adult, child vocalizations, and turns in the conversation. It was explained that "When the children were 18 months old, each additional minute of screen time was associated with 1.3 fewer child vocalizations, for example, and when they were 2 years old, an additional minute was associated with 0.4 fewer turns in conversation.". They concluded that "at almost all ages, increased screen time squelched conversation."
