 The identification of the sources also allows us to propose a processing model in Default Semantics in which three types of contribution to utterance interpretation are distinguished: (i) processing of the sentence (called combination of word meaning and sentence structure, WS); (ii) conscious pragmatic inference (CPI) from three of the sources distinguished above: SD, SC, and WK; and (iii) two kinds of default, automatic meanings: cognitive defaults (CD) triggered by the source IS, and social, cultural and world-knowledge defaults (SCWD).
