Thời gian sử dụng thiết bị điện tử tỉ lệ nghịch với khả năng xây dựng ngôn ngữ ở trẻ nhỏ

nghiên cứu cho thấy trung bình một đứa trẻ mới biết đi xem màn hình gần ba giờ mỗi ngày

Parents have been warned distracting children with devices and having more screen time can lead to them learning fewer words (học ít từ hơn), according to new research.

More than 200 Australian families were tracked for two-and-a-half years with toddlers fitted with a device to record 16 hours a day of audio in the family home.

When the team from the Telethon Kids Institute waded through the 7,000 hours of audio they found toddlers in the study were averaging three hours of screen time a day, and that lost learning quickly added up.

"For the three-year-olds in our study, we showed that for one minute of screen time they were hearing seven fewer adult words, they were speaking five fewer words themselves and they were engaging in one less conversation each day," senior research officer Mary Brushe said.

According to findings published today in the Journal of the American Medical Association Pediatrics, screen time could be robbing the average three-year-old of 1,100 adult words, 840 vocalisations and 194 conversations (đối thoại) a day.

"What we know from previous research is that the more words and conversations that children can have the better when it comes to their early language development (phát triển ngôn ngữ) — and so we want to see those numbers as high as possible," Dr Brushe said.

The average child hears between 5,000 and 35,000 words a day, meaning the significance of those lost words can vary. The researchers stopped short of linking the learning loss to the speech delay impacting a quarter of Australian students starting primary school (trưởng tiểu học).
