In this special issue we consider the development of social psychology in three developed-world countries/regions: Australia, Canada, and Europe and in three majority-world countries/regions: India, Taiwan, and Latin America. Each author examines how social psychology has uniquely evolved from an imported discipline just introduced to their country or region into a mature, autochthonous science regularly contributing to the world's research literature. Whether arising from a focal indigenization process or simply adapting and shaping the discipline to address the special issues arising within each country, insights are revealed about the special form and process the discipline has taken within geographically diverse countries.
