Pablo comes from a low-income family, but he worked hard in school and earned a full
scholarship to Stanford University. Pablo is worried that his peers and professors will recognize
his background and treat him differently, so he wears new clothes and attempts to hide his accent
on the first day of classes. When Pablo goes home for the weekend, he leaves his new clothes
behind in his dorm and does not mask his accent. Which sociological concept best explains
Pablo's behavior and interactions with others?
