The growing phenomenon of "media multitasking"—using several forms of media at the same time—multiplies that figure to 8.5 hours of media exposure daily. Media exposure begins early, increases until children begin school, then climbs to peak at almost 8 hours daily among 11 and 12-year-old children. Media exposure is positively related to risk-taking behaviors and is negatively related to personal adjustment and school performance.[44]
