Different parties turn to Nordicom and the Clearinghouse on Children, Youth and Media with questions on the influences of especially mediated violence. From time to time the Clearinghouse has highlighted the main conclusions that can be drawn from research regarding such issues. In this publication, Dr. Cecilia von Feilitzen, Scientific Co-ordinator at the Clearinghouse, has attempted to classify research findings into a more concise form than is perhaps common. There are different types of mediated violence and different types of influences. We hope that this publication will answer some of the questions so often asked by various groups in society.
