Experimental studies investigating logical reasoning performance show very high error rates of up to 80% and more. Previous research identified scalar inferences of the sentences of logical arguments as a major error source. We present new analytical tools to quantify the impact of scalar inferences on syllogistic reasoning. Our proposal builds on a new classification of Aristotelian syllogisms and a closely linked classification of reasoning behaviors/strategies.
We argue that the variation in error rates across syllogistic reasoning tasks is in part due to individual variation: reasoners follow different reasoning strategies and these strategies play out differently for syllogisms of different classes.
Analyses of scope reconstruction typically fall into two competing approaches: 'semantic reconstruction', which derives non-surface scope using semantic mechanisms, and 'syntactic reconstruction', which derives it by positing additional syntactic representations at the level of Logical Form. Grosu and Krifka (2007) proposed a semantic-reconstruction analysis for relative clauses like the gifted mathematician that Dan claims he is, in which the relative head NP can be interpreted in the scope of a lower intensional quantifier. Their analysis relies on type-shifting the relative head into a predicate of functions. We develop an alternative analysis for such relative clauses that replaces type-shifting with syntactic reconstruction. The competing analyses diverge in their predictions regarding scope possibilities in head-external relative clauses. We use Hebrew resumptive pronouns, which disambiguate a relative clause in favor of the head-external structure, to show that the prediction of syntactic reconstruction is correct. This result suggests that certain type-shifting operations are not made available by Universal Grammar.
In this paper I argue for a new constraint on questions, namely that a question denotation (a set of propositions) must map to a partition of a Stalnakerian Context-Set by point-wise exhaustification (point-wise application of the function Exh). The presupposition that Dayal attributes to an Answer operator follows from this constraint, if we assume a fairly standard definition of Exh (Krifka, 1995). But the constraint is more restrictive thereby deriving the sensitivity of higher order quantification to negative islands (Spector, 2008).
Moreover, when combined with recent proposals about the nature of Exh - designed primarily to account for the conjunctive interpretation of disjunction (e.g. Bar-Lev and Fox, 2017) - Dayal’s presupposition follows only in certain environments. This observation allows for an account of the "mention-some" interpretation of questions that makes specific distributional predictions.
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.
This paper compares the modal particle fei (Schlieben-Lange, 1979; Thoma, 2009) with the modal particle/sentence adverb aber (not to be confused with the conjunction aber, ‘but’). Intuitively, both items express some form of contrast and correction. We will show that both are special among discourse particles in the following sense: They make a contribution that is interpreted at a level distinct from the level where at-issue content (Potts, 2005) is interpreted, as is standard for modal particles (see Gutzmann, 2015 and the references therein). But more interestingly, they exclusively relate to propositions that have not entered the Common Ground via being the at-issue content of an assertion made by the addressee.
This paper experimentally investigates presupposition projection from the scope of the quantifiers every and at least one, as triggered by the factive verb be aware and the iterative adverb again.
The first issue we are concerned with is whether presuppositions project universally or existentially from quantified sentences. Different theoretical accounts endorse opposing views here (e.g., Heim, 1983; Geurts, 1999; Beaver, 2001; Schlenker, 2008, 2009; Fox, 2012), while recent experimental work (Chemla, 2009; Tiemann, 2014) suggests that the force of the projected presupposition varies by quantifier.
The second issue we look at is how the descriptively observed readings arise—in particular, as a direct result output from the projection mechanism, or via additional, independent mechanisms such as domain restriction (e.g., Geurts and van Tiel, 2016): if the domain of the quantifier is restricted, this can yield what looks like non-universal inferences in light of the overall, unrestricted domain, even if the projection mechanism itself yields a universal presupposition. Finally, we test whether the presupposed content also forms part of the entailed content, at least for certain triggers (Sudo, 2012; Klinedinst, 2016; Zehr and Schwarz, 2016).
Our results yield clearly different patterns for every and at least one, with every giving rise to universal presuppositions, which, to a very limited extent, can be weakened by domain restriction, and at least one overwhelmingly giving rise to non-universal presuppositions. Our results also indicate the availability of presupposition-less readings for both triggers in the task at hand, apparently more prevalent than domain restriction. Thereby, we present novel evidence that helps to pinpoint which of the theoretical options can be substantiated experimentally.
Tiwa (Tibeto-Burman; India) has two series of epistemic indefinites: one whose epistemic effects arise via an anti-singleton constraint similar to Spanish alg´un (Alonso-Ovalle and Men´endez-Benito, 2010), and another, wide-scope indefinite whose epistemic effects must be derived differently. I propose that for these latter indefinites, ignorance arises not through domain constraints, but as a result of their choice functional nature through competition with other indefinites. Tiwa’s wide scope indefinites then constitute a new kind of epistemic indefinite, showing that ignorance implicatures for indefinites can arise through different sorts of competition.
Depiction verbs such as paint license i(mage)- and p(ortrait)-readings; for instance, Ben painted a cow can convey that Ben produced an image of an unspecific cow or a portrait of a specific cow. This paper takes issue with a property-based intensional analysis of depiction verbs (Zimmermann, 2006b, 2016) and instead argues for an extensional account. Accordingly, the i-reading is rooted in the introduction of worldly representations by the explicit noun cow as such, whereas the p-reading is rooted in the interpolation of an implicit representation via coercion. This take on the ambiguity captures the following key traits. On i-readings, only representations are accessible to quantifiers and anaphors; moreover, intensional effects such as substitution failure disappear once ordinary objects and representations are adequately distinguished. P-readings, by contrast, involve representations that depend on the portrayed ordinary objects as particulars; correspondingly, only ordinary objects are accessible to quantifiers and anaphors. The proposal is spelled out in Asher’s (2011) Type Composition Logic.
This paper is an attempt to systematically investigate how contrastive focus interacts with various types of not-at-issue content (co-speech and post-speech gestures, lexical presuppositions, and appositives). I look, in particular, at when focus forces at-issue interpretations of typically not-at-issue content, when it does not, and when such at-issue interpretations are impossible even to satisfy focus-related requirements.
I conclude that the main factors affecting how a given type of content aligns along these dimensions are its prosodic (in)dependence and level of attachment in the syntax. The two factors also interact in a non-trivial way, in particular for gestures, which I use as a basis for an analysis of gestures that does not assume that their temporal alignment directly determines their semantics (contra Ebert and Ebert, 2014; Ebert, 2017; Schlenker, 2018), but instead relies on syntax/semantics and syntax/prosody interaction.
Reference of pronouns may be constrained via lexical presuppositions, including marked F-features, implicated presuppositions, and deictic center shifting in certain languages.
This paper explores the acquisition of personal reference terms in Thai, a language that has a highly complex personal reference system. The participants of the study were 67 typicallydeveloping children (TD) and 29 children with autism spectrum disorders (ASD), a population which has long been observed to have difficulties with pronouns. The children were asked to complete simple production and comprehension tasks on personal reference terms. Overall, ASD children performed on par in production but significantly poorer in comprehension than TD children. Given the freedom of choice in the production task, ASD children preferred using fixed referential terms for self-reference, whereas TD children opted for personal pronouns. In terms of comprehension, ASD children were shown to generally be able to detect the person features but they seemed to struggle the most with the pragmatic aspects of personal reference terms. Our results support previous literature that lexical presuppositions are acquired earlier than implicated presuppositions. We add to the literature that the types or the amount of implicated presuppositions matter in acquisition
