Semiotics.

Today in our seminar we spoke about semiotics, the study of signs and symbols. Semiotics consist of the Signifier, what it is you can see/hear, and the Signified, the thing you think of or about, the mental meaning that goes with the signifier. It's not always a specific sign or shape that will create these mental links, colour coding also triggers thoughts, where you see red and blue, you automatically think of red being hot and blue to be cold, just because that's the way your brain has learnt those things.
