Understanding the meaning of an utterance depends not only on shared linguistic knowledge (the interpretation of what is said), but requires also access to what is implicated by that utterance, e.g., affective contents intended as positive/negative evaluations of the state of the world described by the utterance. Some linguistic forms can carry out affective contents. We focus on two of these forms, lexical reduplication (the immediate and intentional repetition of a word) and rhyme (the intentional and structured repetition of phonemes), and examine how these patterns are organized in memory as well as the interaction between short-term memory involved in on-line processing and long-term encyclopaedic memory (collaboration with M. Dominicy, SCoLa, ULB).
