I upvoted this because I'm interested in the same question, I like the methodology. I'm inclined to upvote almost any nontrollish newbie post to encourage participation but that's not the reason here.

But I really suggest spell-checking. A typo in the title is an indicator of low quality esp. here on LW and sets a vote achor even LWs can't seem to ignore. Note that you can still fix typos by clicking on the edit button below your post (the pencil).

Could you give a reference for love psychology?
