First off, there isn't really any all-encompassing "Arab mindset/thought process". (i.e. they are all associative rather than linear thinkers) There are plenty of decent general cultural awareness products that you can pull up with a simple search, but if you're looking for what I read into your statement, it ain't gonna answer the question.
Patai's book is often touted as the thing to read; you'll find plenty of substantive criticism and descriptions of the weaknesses of that work right on this board.
Just my unlettered opinion, but I feel you'll have better luck if you focus your search a bit tighter.
