Note that in the PsycINFO database, many (not all) articles (even those that do not have the full text attached) have a link to their cited references (their bibliographies), and they tell you how many times an article has been cited in the PsycINFO database.
This can be a great tool for other researchers since it's often helpful to note who the authors of an article are citing and who is citing the article you are looking at. Simply click on the link to Cited References to get to the list of references or the link to Times Cited in This Database to see who has cited that article. (See screen shot below.)
Obviously, there would not have been time for other articles to cite an article that had just been published. So to track who is citing a certain article, the original article will likely have to be at least a couple of years old.
