This makes the process more complicated since each participant acts both as sender and receiver. For many forms of communication, feedback is of vital importance, for example, to assess the effect of the communication on the audience.
An example is the relation between sender and receiver: it influences the goal of communication and the roles played by the participants. Schramm's criticism of linear models of communication, which lack a feedback loop, has been very influential.

Relevance is studied in many different fields, including cognitive science, logic, and library and information science. Epistemology studies it in general, and different theories of knowledge have different implications for what is considered relevant.
