Mere-Exposure Effect: Attraction and Intimacy

In this student project, Amber defines the mere exposure effect and gives an example of how it works. As she makes her way to her apartment, she sees various advertisements for a type of beer.

When she reaches into her refrigerator for a beer she has to choose between Stone IPA and Bud Light. Which does she choose and why? What would happen if she had tasted and disliked the advertised beer and then saw multiple ads for it?
