Leslie Seltzer's research showed that girls had a de-stressing response (i.e. increase in oxytocin levels) to hearing their mother's voices, but they did not get a similar response when receiving their text messages.
Both men and women respond positively to non-sexual physical touching by women. Touching by men has no effect.
Michael Kraus, Cassy Huang, and Dacher Keltner's 2010 study on NBA players high-fiving showed that teams where players touched each other more (e.g. high fives, fist bumps, etc.) performed better.
