Psychological Effects

Television violence increases negative behavior. "Most researchers now believe that the evidence is about as strong as the evidence that cigarette smoking causes lung cancer."

— Dr. Daniel R. Anderson

Television, popular in American homes since the 1950s, is the best-studied ICT. Evidence about its effects is mixed. The content of TV programs and the amount of time spent watching, rather than the medium itself, appear to be the primary sources of negative effects. However, many of the cognitive effects of ICTs, positive or negative, are not well understood. Here as elsewhere, further research is imperative.
