Cross-cultural

A way to improve developmental psychology is a representation of cross-cultural studies. The psychology field in general assumes that "basic" human developments are represented in any population, specifically the Western-Educated-Industrialized-Rich and Democratic (W.E.I.R.D.) subjects that are relied on for a majority of their studies. Previous research generalizes the findings done with W.E.I.R.D. samples because many in the Psychological field assume certain aspects of development are exempted from or are not affected by life experiences. However, many of the assumptions have been proven incorrect or are not supported by empirical research. For example, according to Kohlberg, moral reasoning is dependent on cognitive abilities. While both analytical and holistic cognitive systems do have the potential to develop in any adult, the West is still on the extreme end of analytical thinking, and the non-West tend to use holistic processes. Furthermore, moral reasoning in the West only considers aspects that support autonomy and the individual, whereas non-Western adults emphasize moral behaviors supporting the community and maintaining an image of holiness or divinity. Not all aspects of human development are universal and we can learn a lot from observing different regions and subjects.
