On necessary conditions for verbal irony comprehension

The conditions for verbal irony comprehension implicitly or directly claimed as necessary by all of the recent philosophic, linguistic and psycholinguistic theories of verbal irony (Clark and Gerrig 1984; Kreuz and Glucksberg 1989; Kumon-Nakamura, Glucksberg and Brown 1995; Sperber and Wilson 1981, 1986) were experimentally tested. Allusion to a violation of expectations, predictions, desires, preferences, social norms, etc., was confirmed as a necessary condition, but pragmatic insincerity was not. Pragmatically sincere comments can be comprehended ironically. A revised set of conditions was proposed, involving intentional violation of Gricean conversational maxims and the portrayal of a contrast between expectations and reality. A cautionary note was made, however, regarding the viability of a single account of verbal irony comprehension.
