Your smartphone knows which side of the brain you're using

Some people use the left, some the right, but which side of the brain do you primarily use for language? It may seem like a trivial question, but for one thing, if you ever have to undergo any type of brain surgery, the answer can help avoid damage to speech areas.

While lab tests can provide the answer, an app that involves a few minutes of concentration works just as well, according to a study in the journal Frontiers in Psychology.

Furthermore, a version of the app for patients with schizophrenia trains them to improve their focus so that when … Read more

How we test: TVs

Did you know CNET reviews TVs by comparing them directly in a side-by-side lineup, after each has undergone a thorough calibration? Did you know that the main instrument we use to calibrate and measure those televisions costs about $28,000? Did you know that last year we reviewed and rated 54 individual TVs and revamped our ratings system to incorporate value?

Yes, I'm biased, but I consider CNET's TV reviews the best in the business. We've come up with a set of tools and procedures designed to arrive at unbiased results by utilizing industry-accepted video-quality evaluation tools, … Read more

CNET's tech tests for cars

CNET and car reviews may appear to be an unlikely combination, but new cars have become technology platforms, using electronics to inform and entertain drivers, avoid collisions, and even save fuel.

Since we began reviewing cars in 2004, automakers have increasingly included navigation, Bluetooth phone systems, and advanced technologies for playing digital music files in dashboards. In fact, the latest trend is to give cars complete data connections, letting drivers use online search to find destinations or listen to streamed music from an Internet-based service.

Given our technology focus, CNET reviews cars differently than traditional publications such as Car and … Read more
