However, anybody who has struggled with symbols when travelling overseas will appreciate the cultural coding implicit in symbols. Symbols may also create meaning in a less direct, or less overt, manner. Consider the cultural coding of such symbols and their relationship to power.

Visual codes use signs and symbols to create a particular view of the world .
Signs generate meaning through a process of denotation and connotation . Denotation Denotation refers to the literal meaning of the sign - to what is objectively present and easily recognised or identified. It is a 'first order' meaning. Connotation Connotation is a term used to refer to meanings that lie beyond denotation. Connotative readings of signs move beyond the literal and are activated by conventions and codes.
