Scientific American Editor-in-Chief Mariette DiChristina and Dr. Robert Epstein lead a volunteer exercise called "soul gazing" as part of the March 10th, 2010 event "How to Fall in Love and Stay That Way." The talk focused on the psychological, physiological, chemical and social effects of love, including the latest science on fostering emotional intimacy.
And a further and slightly better produced video of trying the exercise with new and established couples.
And for the original articles that kick started this line of enquiry and action here is the abstract from the article (Aron, A., Melinat, E., Aron, E., Vallone, R. and Bator, R. (1997) The Experimental Generation of Interpersonal Closeness: A Procedure and Some Preliminary Findings. Personality and Social Psychology Bulletin, Vol. 23 No. 4, April 1997 363-377): A practical methodology is presented for creating closeness in an experimental context. Whether or not an individual is in a relationship, particular pairings of individuals in the relationship, and circumstances of relationship development become manipulated variables. Over a 45-min period subject pairs carry out self-disclosure and relationship-building tasks that gradually escalate in intensity. Study I found greater postinteraction closeness with these tasks versus comparable small-talk tasks. Studies 2 and 3 found no significant closeness effects, in spite of adequate power, for (a) whether pairs were matched for nondisagreement on important attitudes, (b) whether pairs were led to expect mutual liking, or ( c) whether getting close was made an explicit goal. These studies also illustrated applications for addressing theoretical issues, yielding provocative tentative findings refuting to attachment styk and introversion/ extra version. And here is the whole article on experimenting with love.
