One study you might find interesting (it even comes with a video!) is:
 
"Insights: Museums Visitors Attitudes Expectations -- A Focus Group
Experiment"  (Los Angeles, CA : The J. Paul Getty Trust, The Getty
Center for Education in the Arts, 1991).
 
The best part is that it is free.  I ordered mine from:
 
The Getty Center for Education in the Arts
1875 Century Park East, Suite 2300
Los Angeles, CA  90067
 
It covers some very important issues and the interviews with visitors I found
very informative.
 
I hope this helps.
 
With every good wish,
