Abstract:  Used a standardized version of the Rosenzweig Picture-Frustration Study to investigate, in natural circumstances, how TV programs with aggressive content affected the development of socialization in 194 adolescents (aged 12-16 yrs). Frequent viewers of crime and adventure programs were significantly more aggressive than Ss who rarely watched such programs, regardless of their living situation. Aggressivity among 51 Ss, studied 1 yr before when they were aged 13 yrs, increased. Frequency of TV viewing also had a damaging effect on sleep and consequently on mental and emotional development.
