Two strong contenders for scalar implicature (SI) computation are the pragmatic and the grammatical theories. While the former sustains that context plays a major role, the latter suggests context is required but is lexically and monotonically constrained (Chierchia 2012). In particular, this paper discusses a processing account for SIs that is dependent on the satisfaction of the Strawsonian presupposition of existence, necessary for the realization of the asymmetric entailment pattern among relevant alternatives. This observation complies with the principles of the (...) grammatical view, for it predicts SIs in the presence of contextually empty domains, unlike the pragmatic account whose necessary access to contextual information will cause propositions with empty domains to always return a truth value false, hence blocking any inference. I present online experimental evidence of an acceptability judgment task and recorded response times of both existential and universal sentences containing entities of three kinds: existent (type-a), non-existent but conceivable (type-b), and non-existent and inconceivable (type-c). The data of 25 Colombian Spanish speaking participants were collected using PsychoPy, powered by Pavlovia. The results suggest SIs are computed in types a and b but relatively unsuccessful in type-c. I conclude that the relevant entailment pattern for implicature computation is the Strawson-entailment relation which, combined with the grammatical account, correctly predicts SIs with non-existent but conceivable entities but avoids inference with inconceivable terms.

Acceptable analyticities, i.e. contradictions or tautologies, constitute problematic evidence for the idea that language includes a deductive system. In recent discussion, two accounts have been presented in the literature to explain the available evidence. According to one of the accounts, grammatical analyticities are accessible to the system but a pragmatic strengthening repair mechanism can apply and prevent the structures from being actually interpreted as contradictions or tautologies. The proposed data, however, leaves it open whether other versions of the meaning modulation (...) operation are required. Novel evidence we present argues that a loosening version of the repair mechanism must be available. Our observation concerns acceptable lexical contradictions that cannot be rescued if only a strengthening version of the pragmatic strategy is available. (shrink)

The present paper presents experimental evidence confirming that contextually mismatching scalar implicatures can be generated even when quantifiers range over empty domains. In the literature, this possibility has been interpreted as providing further evidence for a grammatical approach to scalar implicatures. The main result presented here is that scalar sentences with empty domains are judged as more infelicitous when associated with a mismatching implicature than variants with the same empty domains but associated with a non-mismatching implicature. We interpret this result (...) as suggesting that the infelicity judgment associated with the first kind of sentence stems from the cumulative effect of the mismatching implicature and the contextual domain emptiness. Compared to previous literature on blind implicatures, our results indicate that the body of knowledge involved in relevance assignments is restricted to ignoring existential determination while still considering the properties attributed to nonexistent entities. They also show that, while not blocking implicature generation, contextual domain emptiness plays a role in speakers’ evaluation of scalar sentences, reflecting the unconscious nature of scalar implicature generation.
