The research behind it
Start with the finding, then check the study type, source and limits. We select research by topic; a programme’s overall effect does not establish the effect of each activity.A meta-analysis of 42 studies. More screen use was linked to weaker language skills, while co-viewing with an adult and better-quality programmes were linked to stronger skills.
Following about 2,400 children, more screen time at 2 and 3 years was linked to poorer developmental screening results a year or more later.
9-month-old infants learned Mandarin speech sounds from live sessions with a person, but not from the same material shown on video or audio.
