SongeBob Bad for Learning?

In this article it talks about how watching the cartoon  " SpongeBob SquarePants" is bad for preschoolers because just nine minutes of watching the program can cause short - term attention and learning problems. A study was done and it turned out that children performed worse on tests than kids who didn't watch the show. In the study scientists examined a group of 60 4-year-old preschoolers. The scientist divided the children into 3 groups and gave them nine minute assignments. The first group would watch SpongeBob, the second group would watch Caillou, and the third group would not watch T.V at all, they were asked to draw pictures instead. After the nine minute assignment researchers gave the preschoolers some common tests of thinking skills , after examining the results, the scientists learned the group that watched SpongeBob scored worse on the test than the other kids did. I dont think that watching SpongeBob could affect a childs learning because it is just a cartoon and if SpongBob can do that, than im sure other cartoons could to. I know that kids way older than preschoolers that watch spogeBob and it doesnt affect them at all. I think SpongeBob is just a fun and cool cartoon that kids like to watch because it is ammusing. I kbow that kids that age will conyinue to watch SpongeBob because that study doesnt seem right because that means that is a lot of other cartoons that could have the same results as that study.
