Here's a thread dedicated to all the psychologists, psychiatrists, pediatrics, and other "specialists" who focused on videogame violence and its effects on teens, children, behavior and real-life violence.

Here is a first list :
- [URL=http://www.psychology.iastate.edu/~caa/]Dr. Craig Anderson[/URL], Professor in the Department of Psychology in the University of Iowa. Probably the most active and the best known.
- [URL=http://www.psychology.iastate.edu/~dgentile/]Douglas Gentile[/URL], who runs the Media Research lab at the University of Iowa, and who is also member of the National Institute on Media and the Family. Has already worked with Anderson.
- [URL=http://www-personal.umich.edu/~bbushman/]Brad Bushman[/URL], from the University of Michigan. Has already worked with Anderson.
- [URL=http://www.lrc.edu/psy/dillk/]Karen Dill[/URL], from the Lenoir Rhyne College. She's also member of the Committee on Violence in Video Games and Interactive Media of the American Psychological Association. Her mentor is Anderson.
- [URL=http://www.expertclick.com/ProfilePage/default.cfm?GroupID=745&SearchCriteria=Sexual%20Harassment&Serial=19-382]Elizabeth Carll[/URL], stress and trauma expert. Has co-authored an APA resolution with Dill and Bushman.
- [URL=http://psychology.missouri.edu/person.php?frompage=faculty&user=bartholowb]Bruce Bartholow[/URL], from the Department of Psychological Sciences at the Missouri University. He's specialized in brain imaging, and he's already worked with Anderson.

The main organizations related to this topic (people cited above are sometimes members of them) are :
- The [URL=http://www.apa.org/]American Psychological Association[/URL] (APA)
- The [URL=http://www.aap.org/]American Academy of Pediatrics[/URL] (AAP)
- The [URL=http://www.ama-assn.org/]American Medical Association[/URL] (AMA)
- The [URL=http://www.aacap.org/]American Academy of Child and Adolescent Psychiatry[/URL] (AACAP)
- The [URL=http://www.aafp.org/]American Academy of Family Physicians[/URL] (AAFP)
- The [URL=http://www.psych.org/]American Psychiatric Association[/URL]

The most famous "scientific" declarations they made about media violence are :
- The [URL=http://www.aap.org/advocacy/releases/jstmtevc.htm]joint statement on Entertainment Violence[/URL] written in 2000, co-authored by the APA, the AAP, the AMA, the AACAP, the AAFP and the American Psychiatric Association
- The [URL=http://www.apa.org/releases/resolutiononvideoviolence.pdf]Resolution on Violence in Video Games and Interactive Media[/URL], co-authored in 2005 by Dill, Carll and Bushman.
- The dissertation [URL=http://www.psychology.iastate.edu/faculty/caa/abstracts/2000-2004/00AD.pdf]Video Games and Aggressive Thoughts, Feelings, and Behavior in the Laboratory and in Life[/URL], written in 2000 by Anderson and Dill.

Note that I only included "specialists" who work on the effects of videogame violence. This thread is dedicated to them only. Plus, the people cited above often work together and have the same opinions, so that's why I regrouped them in a single thread, and that's also why I don't include people such as Dave Grossman (who already has his own thread anyway) or Kimberly Thompson (who doesn't work on videogame effects, but on the level of violence in games themselves).
