Bootstrapping in Psychology
When I embarked on using bootstrapping in my research I found this chapter/lecture notes by Cosma Shalizi very useful:


The Bootstrap, 36-402, Advanced Data Analysis, 3 February 2011
http://www.stat.cmu.edu/~cshalizi/402/lectures/08-bootstrap/lecture-08.pdf


I see now that he has also written a short introduction for American Scientist


Shalizi, C. (2010). The bootstrap. American Scientist, 98(3),
186-190. http://www.americanscientist.org/libraries/documents/201048159157846-2010-05Shalizi.pdf


We published this paper, which uses bootstrapping in the third analysis (and so may directly answer your question).

Aside from mere egotism on my part, the analysis code for the paper is available, so you can see mechanically how I did it for my analysis (in Python)
