Intuition and Psychology
Here is an interesting article that just came out in the British Journal of Psychology. It's about various psychologists' conceptions of intuition and how research about intuition might be fruitful. The article also has an extensive bibliography. It's a good starting point for further studies into the psychology of intuition. (Note: You will need your asurite to access the article. If you don't have one, the article is the first in the Feb. 2008 issue of BJPsych.)
