What aspects of character development did modern 20th century novelist begin to explore?

the Literature of the 20th century refers to world literature produced during the 20th century (1901 to 2000).

In terms of the Euro-American tradition, the main periods are captured in the bipartite division, Modernist literature and Postmodern literature, flowering from roughly 1900 to 1940 and 1960 to 1990[1] respectively, divided, as a rule of thumb, by World War II. The somewhat malleable term of contemporary literature is usually applied with a post-1960 cut off point.
