In Graphic Design Theory by Meredith Davis, the representation chapter tells you a lot about understanding signs and symbols and how they change in terms of context. When the context of a sign changes, the meaning of it can completely change, specifically talking about a "context of culture."
Something that really stuck out to me was talking about connotative function of a sign and how that changes depending on context. The example of a saluting solder and how it could connote "respect, authority, allegiance, blind obedience, or camradrarie." Furthermore, the uniform and the symbols that are on it then changes or emphasizes the meaning that you originally derived from them saluting. These contexts, or maybe even these preconceived notions, change how we process certain messages or situations.
Currently, I'm working on redesigning a communication model that incorporates failure and ideation. Something that I kept thinking of is the ideal of personal noise, such as preconcieved notions and expectations that affect how you process a message. This personal noise not only affects the sender but also the receiver and thus can completely distort the message. I feel like this concept of representation definitely resonates with the work and ideas I'm trying to convey in my communication model, which made reading about it much more enjoyable and easy to understand.
