We begin this paper by reviewing the core tenets and principles of the symbiotic approach of sociocultural change or the “Proactive-interactive- symbiotic approach to long-term cultural change”, that we had proposed several years ago, and by representing it in brief for the benefit of our readers. We also then review and go through various others concepts centered on, and pertaining to acculturation, enculturation, and transculturation, and compare them with the already preexisting concepts in the market. We also then go on to explain why conjunct studies of acculturation, transculturation, and deculturation processes of various types need to be carried out, and lay forth their real world utility as well. We do this by examining the different types of acculturation, transculturation, and deculturation processes and methods from the aforesaid perspective. We also provide various case studies drawn from different communities from different parts of the world around these concepts to beef up our case, and lend more credence to the tenets of our thesis. Last, but not the least, we explain why these concepts could form an essential and an intrinsic component of post-colonial studies, and form an intrinsic part of our globalization of science movement as well. This would naturally lend a more scientific flavor to cultural studies in general, and post-colonial studies in particular.
