In what will appear to be blatantly obvious to many grandparents and many of the babyboom generation, when children have TV sets in their bedroom they don't do so well at school tests.
Wouldn't you know it? the kids with bedroom TV sets have lower Standardized Test scores.
In a new study by researchers at the Stanford University School of Medicine and Johns Hopkins University, it appears that third-graders with televisions in their bedrooms performed significantly worse on standardized tests than their peers without, but conversely, those with access to a home computer achieved higher test scores.
These differences remained static regardless of the amount of time the students reported spending on homework.
Dr Thomas Robinson, the senior author of the study, is the director of the center for healthy weight at Lucile Packard children's hospital at Stanford, and associate professor of pediatrics at the school of Medicine.
In 2000 Robinson collaborated with lead author Dina Borzekowski, assistant professor in the Department of Population and Family Health Sciences at the Bloomberg School of Public Health at Johns Hopkins.
In their study they surveyed approximately 350 third-graders at six public elementary schools in northern California, and found that more than 70 percent of the students reported having a television in their bedroom.
These particular students scored between seven and nine points lower on standardized mathematics, reading and language arts tests than did their peers.
Students with access to home computers meanwhile scored between seven and nine points higher than those without.
The highest average scores achieved were by students with computer access and without a bedroom TV.
The students with a personal television and without computer access at home on average scored the lowest.
