Yesterday, we had an aggressive attack on computer games from the Danish National Television News [DR: Tv-avisen]. The claim was that in fact computer gaming created killers like the German mass murderer who killed 17 people including himself. This was due to overdose of dopamine while playing. Dopamine is a chemical substance, which the body under ceartain circumstances may release in the brain. The dopamine accompanies a feeling of tension and joy.

Huizinga's definition of play is "a voluntary activity or occupation executed within certain fixed limits of time and place, according to rules freely accepted but absolutely binding, having its aim in itself and accompanied by a feeling of tension, joy, and the consciousness that it is different from ordinary life."

Well, neuro science have proved what we already knew. We get a feeling of tension and joy while playing, but that does not make us lunatic killers.

Maybe, we should find other causal reasons for what he did! There was indeed a social reason for, why the German killer did his crime. He had been expelled from High School six months ago, and did not dare to tell his parents. This of course is not visible to a neuro scientist.
