Does Lack Of Touch Cause Aggression?

Anthropolical studies have shown that cultures with less touching tend to be more aggressive than cultures with close touching:

And while this study doesn't prove that lack of touch increases aggression, Field said, monkey studies suggest one possible way this link might work. Monkeys who have been deprived of touch have shown a drop in the level of serotonin, she wrote. Their levels of cortisol increase, which makes them more agitated and aggressive. At the same time, massage therapy has been shown to lower the level of cortisol and increase the level of serotonin - hence, a relationship between increased touch and decreased aggression.
