Bettina Cornwell is an expert in advertising and marketing. Her primary research interest is in difficult and high context communications where many things are left unsaid and meaning is derived from actors, symbols, logos, and the social milieu. This is found in indirect marketing, such as sponsorship, celebrity endorsement and brand placement. It is also central in international communication and in many public policy issues, such as how one communicates with children or how one encourages environmentally friendly behavior. She is also interested in memory for these types of communications and their immediate and long-term influence on behavior.
