Russ1642: Females not known to each other, hugging only female partners in a clinical setting. Also, all of the volunteers were asked to wear blindfolds to prevent them from seeing the person they would be hugging. The experiment consisted of asking 48 female volunteers to hug a female researcher. Due to the blindfolds, the type of hug was in the control of the researcher and consisted of either a criss-cross hug or a neck-waist hug. Afterward, each of the volunteers was asked to rate their level of pleasure regarding the hug.Nothing new. I've seen quite a few documentaries on this experiment.
