I had to modify the original question, but think I was able to preserve its original intent. The focus of the yellow wallpaper in the story has several specific purposes. I think that the most pressing of them is that the woman's construction of what is happening in the yellow wallpaper as she studies it from her bed of confinement is the only freedom she is allowed. She is not allowed to maintain a journal, leave the bedroom, express what she is feeling, or do anything of the sort. In the end, all she can do is study the wallpaper. Through this analysis, she projects her own condition of being trapped and subjugated on the designs in the wallpaper. The importance is to reflect the theme of the role of women and social forms of subjugation that is a part of the experience of being a woman in society. In showing how the narrator is able to construct and transfer her own reality upon that of the wallpaper, it brings to light that women's voices will have to be heard. On some level, either society will create forums where this voice can be expressed properly and with a sense of productivity and construction or it will be expressed in a destructive manner. The story seems to be suggesting that society must make the choice as to how to approach the experience of women in the modern setting.
