This paper uses examples of conversational understandings, misunderstandings and non-understandings to explore the role of prototypes and schemata in conversational understanding. An investigation of the procedures by which we make sense of lexical items in utterances by fitting prototypes into schemata is followed by an examination of how schemata are instantiated across conversational sequences by means of topics. In interaction, conflicts over meaning illuminate the decisive role of social and cultural factors in understanding. Overall, understanding is seen to be critically (...) dependent on principles of categorisation and contrast, which form the basis of both cognitive and sociocultural means of organisation. (shrink)

This paper describes a semantics for modal terms such as can and may that is intended to model the mental representation of their meaning. The basic assumption of the theory is that the evaluation of a modal assertion involves an attempted mental construction of a specified alternative to a given situation rather than the separate evaluation of each member of a set of possible alternatives as would be required by a “possible worlds” semantics. The theory leads to the conclusion that, (...) contrary to what is often assumed, modal auxiliary verbs are unambiguous. (shrink)
