Depictions of Women in American Literature 1860-2009

Have portrayals of women in literature changed over time? The assumption was that the portrayals of women have changed over time in one way or another. The analysis shows, quite contrary to the assumption, that there is no difference between the portrayals of women in the 19th century compared to the 21st century. All of the multiple correspondence analyses indicate that whether the novel was written before or after the social revolution has very little influence on how the lexemes were used. So I can only conclude that nothing has changed in this area, the hypothesis was wrong
