How does Richard Littlebear's story illustrate the perspective that cultural anthropology can bring to the study of people and their ways of life?

I’m having a hard time what’s a mock study is:

In the article by Sarrett on explanatory models for autism in Kerala, India, how does this case study demonstrate the point that Janelle Taylor argued in her article about the book, The Spirit Catches You and You Fall Down? In your answer, first discuss what Taylor means by a "reified" and "essentialist" idea of culture, which she criticizes.  Then use the Sarrett case study about autism to show how Indian culture does not neatly contrast to Western medical culture.
