I think you can look at it from a psychological perspective by reading some
introductory textbook on attitude and identity and follow the references
from there. One book I have (and relevant to your student's topic is) "The
Psychology of Attitude Change and Social Influence" by Philip G. Zimbardo
and Michael R. Leippe, and it has some sections that deal with how our
attitudes (and eventually identities) are formed and how they shift by being
expose to media (of any form -- can be a textbook, a TV, etc.).
"Here is a test to find whether your mission on earth is finished.: If
you're alive, it isn't."
