Article excerpts:
Television seemed to increase the differences that kids saw between the sexes, but mainly between boys and girls. It seemed to have no effect on how children perceived adult roles.
. . .
The biggest effect was on sports – the number of sports events dropped in half in Notel. There was little effect on religious, civic, or business activities. The group most affected was those over 55; their participation in public events dropped dramatically, probably for the obvious reasons.
. . .
Although most aggressive acts were committed by a very few kids, the overall level rose for all children, and for both boys and girls. The levels also rose in Unitel and Multitel, but by nowhere near as much. Kids who were not aggressive before TV increased as much as kids who were.
