This article shows how the construction of transnational migrant communities across international borders poses a challenge to the assumed "natural" isomorphism of space, nations, and cultures that typically exists in theories of cultural and cross-cultural psychology. One of the principal aims of this article is to add to the critical impulse that initially defined the vision of cultural psychology by analyzing how transnational diaspora communities have become new sites for the rethinking of core concepts such as culture, self, nation and (...) identity. By drawing on Gupta and Ferguson's work, I present three important ways through which cultural theorizing can be reconfigured in the present transnational context. 2012 APA, all rights reserved).
