Fay's Semiotics Theory Lesson

Anti-Realism - Realism and Anti-Realism are two sides of a philosophical debate behind the whole basis of accepted scientific truth.
For example: Realism advert - Dyson | Anti-Realism advert - the guardian - the three little pigs

Surrealism - The Rihanna Reb'l Fleur advert's main purpose is to promote and sell the perfume. The other reasons may be that the perfume can change your personality and make you feel more confident. Another reason could be that using the perfume will make you feel good.                        

Semiotics - The study of signs and symbols as elements of communicative behaviour; the analysis of systems of communication such as  as language, gestures, colours or clothing. Used to contrast possible meaning form a text. Is a way to looking at hidden/overt messages that advertisers may use.

The sign - is made up of signified (the concept it represents) and signifier ( the form which the sign takes). When the two meet, it creates the sign.
For example: Signifier: the word or symbol open |  Signified: That the shop is open for business. When we see that a shop has an open sign, our mind processes this and we walk in knowing that the shop is open.
For example: Signifier: the word or symbol stop | Signified: That we should stop whatever we are doing. When we get told to stop, it represents to stop/pause our actions.
