The article “Tots’ TV- Watching May Spur Attention Problems” (San Luis Obispo Tribune, April 4, 2004) describes a study that appeared in the journal Pediatrics. In this study, researchers looked at records of 2,500 children who were participating in a long- term health study. For each child, they determined if the child had attention disorders at age 7 and the number of hours of television the child watched at age 3. They hoped to use the resulting data to learn about how these variables might be related.
