Even the most conscientious parents—who would never dream of leaving their preschoolers in front of a television for hours on end—nevertheless will use the TV in short bursts to keep kids busy. Sometimes you just need those 15 or 30 minutes to make an important phone call, prepare dinner, or just get a little "me" time. And really, how much damage could a half hour or under do to a small child?
As it turns out, quite possibly, plenty. A recent study by psychologists at the University of Virginia in Charlottesville found that even watching just a few minutes of a typical, fast-paced children's cartoon can negatively affect the viewer's mental acuity.1 There has been plenty of research associating young children's television watching with impaired cognitive function over the long term, but not much about what happens after shorter viewing periods.
The 60 four-year-old participants were randomly divided into three groups. The first group watched nine minutes of a "very popular fantastical cartoon about an animated sponge that lives under the sea" (hmmmmm, wonder who that could be?). The second group watched a more educational PBS show about a boy in preschool for nine minutes. The third group didn't watch at all; instead, they spent nine minutes coloring with markers and crayons.
After the nine-minute period, the children were given four tests. They were designed to measure executive function, which comprises working memory, attention, problem solving skills, and the ability to delay gratification. Executive function is widely considered a marker for potential success at school…although, it would seem, not necessarily on Wall Street. >

Not surprisingly, the kids who watched SpongeBob and his pals scored substantially lower than the children in the other two groups. What was more than a little surprising to the researchers was the fact that the children's executive function skills were so diminished after such a short period of watching the cartoon. And let's not forget that there are many parents out there who have no problem whatsoever allowing their young children to watch just these types of shows for hours on end every day.
Satu kajian baru-baru ini oleh pakar psikologi di Universiti Virginia di Charlottesville mendapati bahawa walaupun menonton hanya beberapa minit kartun yang biasa, kanak-kanak pantas ini boleh memberi kesan negatif acuity.1 mental penonton Terdapat banyak penyelidikan mengaitkan televisyen kanak-kanak muda menonton dengan fungsi kognitif terjejas dalam jangka masa panjang, tetapi tidak banyak tentang apa yang berlaku selepas tempoh viewing pendek.
ReplyDelete60 peserta empat tahun secara rawak dibahagikan kepada tiga kumpulan. Kumpulan pertama menonton sembilan minit daripada "kartun fantastis sangat popular tentang span animasi yang tinggal di bawah laut" (hmmmmm, tertanya-tanya yang yang boleh?). Kumpulan kedua menonton PBS menunjukkan lebih pendidikan tentang seorang budak lelaki di prasekolah selama sembilan minit. Kumpulan ketiga tidak menonton di semua; sebaliknya, mereka menghabiskan masa sembilan minit mewarna dengan penanda dan krayon.
Selepas tempoh sembilan minit, kanak-kanak telah diberikan empat ujian. Mereka direka untuk mengukur fungsi eksekutif, yang terdiri daripada ingatan kerja, perhatian, kemahiran menyelesaikan masalah, dan keupayaan untuk menangguhkan kepuasan. Fungsi eksekutif secara meluas dianggap sebagai penanda bagi potensi kejayaan di sekolah ... walaupun, ia akan kelihatan, tidak semestinya di Wall Street.
Tidak menghairankan, anak-anak yang menonton SpongeBob dan sahabat beliau menjaringkan jauh lebih rendah daripada kanak-kanak dalam kedua-dua kumpulan lain. Apa yang lebih sedikit mengejutkan para penyelidik telah hakikat bahawa kemahiran fungsi eksekutif kanak-kanak telah berkurangan begitu selepas apa-apa tempoh yang singkat menonton kartun itu. Dan mari kita tidak lupa bahawa terdapat ramai ibu bapa di luar sana yang tidak mempunyai masalah apa-apa membenarkan anak-anak muda mereka untuk menonton hanya jenis menunjukkan berjam-jam pada akhir setiap hari.
