Alvarado's racial stereotypes theory (1987)

 Alvarado's Theory of racial stereotypes was coined in 1987. It has four key themes in racal representation:

Exotic: Ethnic groups other then white(especially the females) can be seen as exotic and sexy. The group most often stereotyped as this is Latino Americans. Females who are Latino are normally portrayed as sex symbols and very promiscuous people. They are shown as this by being in risqué costumes and normally being involved in controversial behaviour.

Dangerous: Ethnic groups can also be displayed as dangerous through their behaviour. This is a very prevalent theme through Rap music which makes it a very widely 'accepted' stereotype that black males are a very violent ethnic group.

Humorous: Much like the others any 'character' signed as this will give their entire nationality the funny part. There aren't any examples of this that I can think of from Music videos as this character trope is more applied to actual films and TV shows.  

Pitied: A perfect example of pitied is all the adverts for children's charities. They depicted all the starving children who are all of a differing ethnic backgrounds from white. Again this can't really be applied to music videos but a good example from TV is the ethnic minorities that live in 'Ghettos'.
