There is a persistent problem in developmental science, with nearly all of our research focused on urban, middle-class, English-speaking children and families residing in Europe and North America. This poses a challenge for representativeness of participants as well as the generalizability of findings. Despite the diversity of human social life and ecology, we know very little about the extent and range of human variation and how it impacts the developing child. In this talk, I underscore the strong motivation for examining development in diverse contexts. I describe common practices and methods in the sub-field of culture and development. Lastly, I provide a summary of commonalities and differences in development that we have found in our research. I emphasize the need for inter-disciplinary collaborations and partnerships.
