Semiotics
Semiotics, or semiology, is the study of signs, symbols, and signification. It is the study of how meaning is created to the audience, as signs allow us to deconstruct meaning within the media. For example, an extract from a film or TV programme can be analysed to see what is denoted and connoted within the extract. The relationship between the signifier and the signified is referred to as signification. The signifier is any material thing that signifies e.g. words on a page or an image. The signified is the concept that a signifier refers to. There are three different types of signs, they are: Iconic signs – Icons are signs where meaning is based on similarity of appearance, Indexical signs –Indexical signs have a cause-and-effect relationship between the sign and the meaning of the sign. And finally, Symbolic signs – These signs have an arbitrary or conventional link. The word tree, only comes to stand in for the notion of tree because of the conventions of our language.
A combination of signs creates a code that can be understood usually through cultural or social context. Some theorists argue that even our perception of the everyday world around us involves codes. Fredric Jameson declares that ‘all perceptual systems are already languages in their own right.’
Ferdinand de Saussure believed that all the ways humans communicate, through colour, clothing, flags, etc could be analysed as if it were a language. Saussure also believed that things have no link to the names they are given. The connection between the name and the object it is assigned to is learned.
Another theorist: Roland Barthes developed a method so we can analyse and discuss the literal and potential meanings of an image. To indicate the literal meaning of an object/image means to denote it. Connotation, on the other hand indicates potential or suggested meanings. For example red hair could connote evil or the devil.
