The conclusion in any essay should sum up the argument that you have been making from the beginning. It should technically contain no new information. However, it serves a very useful purpose in summing up your argument and presenting your clear point of view. Many teachers, myself included, read through an essay briefly before marking. Typically, we read the introduction first, then the conclusion, before reading the rest. This is a useful tip that you will be using very soon in your research investigation!
Here are a few pointers on what to include in a conclusion in the representation question.
You need to address the ideologies of the producer to get the highest marks. This should be addressed from the start, but the conclusion is a good place to go all out with your ideas. Ideology refers to the messages, beliefs and values of a producer, but we must also assume that for whatever reason, the producer is attempting to manipulate the beliefs of the audience too. This can be for social/political reasons (Top Boy informs the audience of the poverty affecting black London teenagers), financial reasons (the Gucci advert presents a sexualised ideal for the audience to associate with their brand) to more sinister ones (the TV advert to Special K suggests the ideology that women who are thin, white and childish are most successful in life, promoting an ideology of patriarchal hegemony)
One term you will be using in (almost) every representation response is stereotype. But you must answer the question: why do producers use stereotypes? Richard Dyer suggests that it can be used as a shortcut. In the case of Top Boy and Work by Rhianna (two excellent contrasting examples) we see that by representing in these cases black people as pitied, exotic and aggressive, it clearly communicates to the audiences the personalities of these characters. However, as George Gerbner suggests, this may cultivate the ideology that black people only fit in to a few, simple categories, which in turn reinforces hegemonic ideological beliefs. This argument can be adjusted and applied to pretty every representation question, including women, men, age and national identity!
You must also discuss if and how representations are typical and/or challenging. If so, why has the producer chosen to challenge stereotypes? Is this to influence the dominant ideology surrounding certain groups for the benefit of everybody? Or is it simply a narrative device designed to make the text more exciting for audiences? And how do you personally feel about this?
