Nancy Jensen, right, watches as her children, Elizabeth, 6, left, and Joe, 2, center, play with a building set and other toys, Tuesday, Feb. 12, 2013 at their home in Seattle. Nancy was a participant in a new University of Washington study on the effects of television viewing on kids that will be published Monday, Feb. 18, 2013. As a result of what she learned, her children spend more time with hands-on toys and less time watching TV.
