ABCD Study Investigators publish research about screen media activity
Dr. Martin Paulus, ABCD Study investigator at the Laureate Institute for Brain Research in Tulsa, Oklahoma, along with several other ABCD Study Investigators, published a scientific article about the impact of screen media activity (e.g., watching television or videos, playing video games, or using social media) on brain development. The data summarized in the article were collected from ABCD Study participants across all 21 sites. Among the article’s highlights are that (1) screen media activity is a common recreational activity in youth and (2) certain types of screen media activity may be associated with specific brain structural patterns.
In a recent segment of the television news program 60 Minutes, Anderson Cooper interviewed Dr. Gaya Dowling, Project Director for the ABCD Study, about the impact of screen time on adolescent brain development. Dr. Dowling noted, “It won’t be until we follow [the participants] over time that we will see if there are outcomes that are associated with the differences that we’re seeing in this single snapshot.” Read about this research in The New York Times.
