Is it possible to say that certain lexical items encode both conceptual and procedural information? Verbs of cognitive attitude like the verb assume lexicalize the interplay of epistemic and evidential qualifications of states of affairs. For this reason, they play a crucial role in communication: they help the hearer recover the speaker’s attitudes towards the proposition expressed and the correct explicature of an utterance (Ifantidou 2001). They furthermore guide the hearer in assigning an “existential status” to the information that is communicated, so that he can steadily store it in his representation database and use it as a premise in reasoning. Since the assignment of an epistemic and evidential status to the information retrieved through whatever means, including communication, is a fundamental cognitive operation, it could be hypothesized that verbs of cognitive attitude not only encode conceptual information, but procedural information as well.
