Ideology
In the 2012 people's choice awards, Katy Perry left with lots of awards as well as nominations. Her awards were:
-Favourite tour headliner
-Favourite music video for her song Last Friday Night
-Favourite song of the year with E.T
-Favourite female artist

Katy Perry is 27 years old and has achieved all of these awards and is a well recognised music artist and has also been voted favourite female artist of 2012, therefore she would have reached Maslow's esteem stage of the pyramid because of her achievements and she will be confident.

Ideology is related to peoples ideas, values and beliefs. For example if a young music artist was driving a really nice expensive car and people especially boys would idolise them and then feel like what they want is that car. They also would feel like they should be driving a car like that when they reach the same age as the artist, so ideology is a very influential thing. With Katy Perry being a recognised and very successful music artist at twenty seven makes people idolise her and think that they should have achieved something of a similar standard at the same age.
