A recent study by Erika Robles-Estrada, Perla S. del Carpio-Ovando, and Lucas G. Gago-Galvagno, has revealed that excessive use of screens can delay cognitive and motor development in Mexican infants. The study included 91 caregivers of children between 12 and 36 months of age.
The results show that infants spend between 3 and 4 hours a day in front of screens, mainly television. The greater the exposure, the less lexical density and a delay in motor and language development milestones will be observed. However, the study also found that the presence of an adult during screen use improves these indicators, suggesting that adult supervision can mitigate some negative effects.
This study highlights the need to moderate screen use in the first years of life and highlights the importance of active participation by adults during the time children spend in front of digital devices.
