(CNN) - We've heard it all: from the correlation between TV viewing and childhood obesity to the idea that excessive TV viewing can negatively affect children's grades.
But according to a new study, watching TV might actually boost your child's self-esteem - that is, if he's a white male.
Parents of white girls and African-American children, however, might want to limit the amount of time their kids spend in front of the tube. The self-esteem of white girls, black girls and black boys decreases with TV consumption, says the study, published in Communication Research.
Over the course of one year, Kristen Harrison and Nicole Martins surveyed about 400 black and white Illinois students. All of the 7- to 12-year-olds are from lower-middle to upper-middle socioeconomic communities, said Harrison, a professor of communication studies at the University of Michigan. Black children surveyed, on average, spent an extra 10 hours watching TV each week.
With the definition of self-esteem being an overall feeling of self-worth, Harrison told CNN, kids were asked reverse-coded questions such as, "Are there a lot of things about yourself you would like to change?"
While the study focused solely on how the amount of time spent in front of the TV affects a child's self-esteem, the programs likely are what give white boys a confidence boost, said Amy Jordan, director of the Media and the Developing Child sector of the Annenberg Public Policy Center of the University of Pennsylvania.

San Diego, California (CNN) – For anyone who wants to make a serious play for the Latino vote - and not just go through the motions - here's what you need to know: Latinos are single-issue voters.
The issue is respect. Or, as we say, respeto. Nothing else matters. If you want the votes of Latinos, show some respect. Or we'll show you the door.
I know what you're thinking. What's so special about this constituency?
Three things: Size, geography and unpredictability. In 2008, about 10 million Latinos voted; the 2012 figure could be higher. Latinos are well represented in "battleground" states (i.e. Colorado, Florida, Nevada, New Mexico). And, in the case of the Mexicans and Mexican-Americans who make up about 66% of the U.S. Latino population, they're in play because they have shown a willingness to vote for moderate Republicans even though most are registered Democrats.
Polls show that Latinos are just like other voters in that they care about education, jobs, the economy and health care. But their antennae go up when they see politicians using the immigration issue to scare up votes - and, in the process, treating them like piñatas.
