Relevance theory is a proposal by Dan Sperber and Deirdre Wilson that seeks to explain the second method of communication one that takes into account implicit inference s. It argues that the hearer reader audience will search for meaning in any given communication situation and having found meaning that fits their expectation of relevance, will stop processing. Relevance theory contrasted with the Conduit Metaphor There are two ways to conceive of how thoughts are communicated from one person to another. The first way is through the use of strict coding and decoding, such as is used with Morse code . In this approach the speaker author encodes their thoughts and transmits them to their audience. The audience receives the encoded message and decodes it to arrive at the meaning the speaker author intended. This can be visualized as follows br Speaker s thought intention encoded transmitted decoded Intention thought understood. br This is usually referred to as the Code Model or the Conduit ... in inferential communication that each other have the notion of relevance in their minds.
