http://pss.sagepub.com/content/early/2010/03/19/0956797610366090.abstract - I can't seem to locate this article on HCC Library site
The journal Psychological Science is available in the database Academic Search Complete from 1990 to present with a 1 year embargo on full text. So, you didn't do anything wrong - the most recent year's worth of articles are only indexed (no full text available).
But there's some good news - there is an "In Press" copy of the article available for download at CiteSeerX
If you need a copy of the article as it appeared in the actual journal, we will be happy to try and obtain a copy for you by interlibrary loan - a service available to HCC faculty. Please feel free to let us know if this is the case and we will process your request.
