The document discusses various models and frameworks for understanding communication and advertising, including:
1) Communication feedback models that describe the steps in the communication process from sender to receiver.
2) Models for understanding consumer response to advertising, including the elaboration likelihood model and cognitive response model.
3) Integrated marketing communications (IMC) models which aim to coordinate marketing components to influence brand information and build profitable relationships.
The key point is that understanding how consumers process information and how advertising fits into the communication process helps to set objectives and evaluate advertising results more effectively.
