Prior work has shown that adults vary widely in extent to which they adopt or of utterances, yet underlying reason for this variation is unknown. Drawing on theoretical models implicature derivation, we explore hypothesis cognit...

Different theoretical accounts have been proposed to explain how and when implicatures are derived. We will focus here on one particular aspect of this debate, namely, the question of the “cost” of implicature computation, which has ...
