The New York Times published an obituary, "Leonard Eron, 87, Is Dead; Researcher on TV’s Tie to Violent Conduct" by Jeremy Pearce on May 12, 2007.
Here is an excerpt:
Leonard D. Eron, a psychologist whose pioneering studies of youth violence led him to conclude that television had a significant role in prompting destructive behavior in later life, died on May 3 at his home in Lindenhurst, Ill., near Chicago He was 87.
The cause was congestive heart failure, his family said.
In 1960, Dr. Eron (pronounced EE-rahn) began a long-term study of aggression in more than 800 children living in upstate New York. With two other clinical psychologists, Monroe M. Lefkowitz and Leopold O. Walder, and additional researchers, he interviewed 8-year-old children and their parents, evaluating behavior and opening a database to follow the children into adulthood. That work, which continues, became known as the Columbia County Longitudinal Study.
Rather than relying on asking the children about their own habits, Dr. Eron and his colleagues questioned their peers and asked them about threats, pushing and other violent tendencies. They also interviewed parents about the television programs most often watched by their children, and rated the programs for their level of violence.
The Columbia County subjects were studied again in 1970, 1980 and 2000 (the most recent results followed 61 percent of the original participants), and the researchers found a correlation between the viewing of violent television shows in youth and the expression of violence in adulthood, in terms of criminal records and other measurements.
“Television has great teaching potential,” Dr. Eron told The New York Times in 1993. “It’s just been teaching the wrong things.”
Dr. Eron and his collaborators also identified violent parents as another important factor in the development of overly aggressive children, and found that a long-term association between early exposure to violence, whichever the source, and aggression in later life held true for both sexes.
The study’s findings have been widely cited, and though some critics pointed out that he had limited data on some of the long-term outcomes, Dr. Eron became a recognized voice on the subject. He was president of the International Society for Research on Aggression from 1989 to 1991, testified before Congress on youth violence in 1992 and was co-editor of an influential 1986 research report, “Television and the Aggressive Child: A Cross-National Comparison.”
L. Rowell Huesmann, a professor of communication studies and psychology at the University of Michigan, said Dr. Eron had became interested in ways to mitigate violence and the harmful effects of television. In the 1980s and ’90s, he helped prepare school programs in Chicago, neighboring Oak Park and other cities to counsel children about how to deal with violent images. He also advised teachers and parents about the usefulness of encouraging positive behavior in students without placing undue emphasis on punishment for unwanted behavior.
