Schlenker (2012) proposes that when framed within a modern Stalnakerian view of presupposition and common ground (Stalnaker, 1998, 2002), Maximize Presupposition! (Heim, 1991; Sauerland, 2008) can be viewed as a special case of the maxim of Quantity (Grice, 1975).
We provide data suggesting that in some cases, Maximize Presupposition! applies even when speakers are not expected to use a presupposition as vectors of new information. We argue that these data support the view that Maximize Presupposition! is an independent pragmatic principle, distinct from Quantity.
There are two main approaches to change of state verbs. One adopts an approach in terms of a total change (becomeP, for base predicate P), i.e., a change from not being in the extension of the base predicate to being in it. The other adopts an approach in terms of a relative change (becomemore P, for base predicate P), i.e., a change for a theme in which it increases in the extent to which it holds the property denoted by the base predicate. Different languages have been analyzed using one or the other approach. I argue that both proposals are actually appropriate for analyzing related but not (completely) overlapping phenomena in the domain of derived change of state verbs in the very same language. This proposal is based on the discussion of change of state verbs in Southern Aymara that are derived with the suffixes -pta and -ra. I show that verbs with -pta convey the meaning of total change and that verbs with -ra convey the meaning of relative change. I further discuss how expressions with -pta and -ra interact: expressions with -ra implicate that the theme does not change from not being in the extension of the base to being in it. I propose an account in terms of scalar implicatures in which -pta and -ra are lexical alternatives, thus extending the domain of linguistic phenomena for which the computation of scalar implicatures is relevant.
Previous research on scalar implicature has primarily relied on metalinguistic judgment tasks and found varying rates of such inferences depending on the nature of the task and contextual manipulations. This paper introduces a novel interactive paradigm involving both a production and a comprehension component, thereby fixing a precise conversational context.
The main research question is what is reliably communicated by some in this communicative setting, when the quantifier occurs in unembedded positions as well as embedded positions. Our new paradigm involves an action-based task from which participants’ interpretation of utterances can be inferred. It incorporates a game–theoretic design, including a precise model to predict participants’ behaviour in the experimental context.
Our study shows that embedded and unembedded implicatures are reliably communicated by some. We propose two cognitive principles which describe what can be left unsaid. In our experimental context, a production strategy based on these principles is more efficient (with equal communicative success and shorter utterances) than a strategy based on literal descriptions.
In recent years, experimental research has demontrated great variability in the rates of scalar inferences across different triggering expressions (Doran et al. 2009, 2012, van Tiel et al. 2016). These studies have been taken as evidence against the so-called uniformity assumption, which posits that scalar implicature is triggered by a single mechanism and that the behaviour of one scale should generalize to the whole family of scales. In the following, we present an experimental study that tests negative strengthening for a variety of strong scalar terms, following up on van Tiel et al. (2016). For example, we tested whether the statement John is not brilliant is strengthened to mean that John is not intelligent (see especially Horn 1989). We show that endorsement rates of the scalar implicature (e.g., John is intelligent but not brilliant) are anti-correlated with endorsements of negative strengthening. Further, we demonstrate that a modified version of the uniformity hypothesis taking into account negative strengthening is consistent with van Tiel et al.’s data. Therefore, variation across scales may be more systematic than suggested by the van Tiel et al. study.
