Describe and define the mere exposure effect

Describe and define the mere exposure effect.  Include information about how, when, and why, it does and doesn’t work. Generate two examples – one where you feel that you came to like a person, object, or entity due to mere exposure, and the second, an example of something you dislike so strongly that no amount of exposure will change your attitude, or perhaps even make it worse.  Again, be detailed and specific.
