We’ve just filed an amicus brief on behalf of Experimental Psychologists in the Fisher v. Univ. of Texas case. It discusses the phenomenon of stereotype threat.

Proper bluebook citation, courtesy UCLAW librarians, is:
Brief of Experimental Psychologists. et al. as Amici Curiae Supporting Respondents, Fisher v. University of Texas, (August 13, 2012) (No. 01-1015).
In a reference list the APA will use the bluebook style. Citing the brief within the text of an article the APA would use: Brief of Experimental Psychologists, (2012).
For other amicus briefs, SCOTUS Blog keeps a list, which should be updated soon.
