Abstract: Cross-linguistically, predicates with both initial-state and change-of-state components tend to encode them as presupposition and assertion, respectively. Bade et al. (2024) argue on the basis of a series of artificial word learning experiments that this cross-linguistic tendency reflects conceptual biases privileging changes-of-state over initial-states. In their experiments, they gauged how participants encoded the initial-state and change-of-state entailments of a nonce verb wug, and they interpret their results as suggesting that participants generally encoded the initial-state entailment as a presupposition and encoded the change-of-state entailment as the assertion. This finding, they argue, favors their conceptual-bias hypothesis over competing accounts. In this talk (joint work with Athulya Aravind), we further test the validity of Bade et al.’s paradigm via an additional experiment where we both try to replicate their original effect and, in parallel, ascertain whether their results generalize to a nonce initial-state/change-of-state predicate other than the one that they test. We not only fail to extend Bade et al.’s results to our new nonce word but also fail to replicate their original effect: our participants overwhelmingly treated Bade et al.’s wug and our new nonce word as non-presuppositional. A closer look at Bade et al.’s original studies suggests that non-presuppositional construals were common there, too, and we discuss several reasons why this could have been the case. All told, our outlook is pessimistic: adult artificial word-learning tasks do not, in fact, illuminate the mechanisms of presupposition triggering.
