Epistemic reasoning in pragmatic inferencing by non-native speakers: The case of scalar implicatures

Scalar implicatures involve inferring the use of a less informative term (e.g. some) to mean the negation of a more informative term (e.g. not all). A growing body of recent research on the derivation of scalar implicatures by adult second language (L2) learners shows that while they are successful in acquiring the knowledge of scalar implicatures, a property at the semantics–pragmatics interface, it remains controversial as to which mechanism, default or non-default, could account for L2 learners’ derivation of scalar implicatures. The present study used an online self-paced reading task to address this issue by examining the role of the speaker’s knowledge state in the interpretation of the existential quantifier some by Chinese-speaking learners of English in incremental sentence processing. Results showed that both L2 and native participants demonstrated comparable online sensitivity to the speaker’s knowledge state. Critically, when the scalar implicature was computed in situations where the speaker was more likely to know whether the statement with the stronger alternative was true, it gave rise to measurable reading latency, indicative of increased processing costs. We conclude by arguing that our findings are compatible with the context-driven models within the Gricean tradition.

A Pragmatic Analysis on Vague Language Used in Disaster News Articles on Thejakartapost.com

This paper presents the findings analysis of categories and functions on vague language used in disaster news articles on Thejakartapost.com based on the theory of Channell (1994). In the journalism context, especially in disaster news article, the information often contains vague language that has imprecise statement since it is harmful. Therefore, to avoid wrong statements, the reporters often use vague language in presenting information accurately. The study employed a qualitative descriptive method. All data were 24 news articles. There were 12 news articles of natural disasters and 12 news articles of human-caused disasters. The period was from April 2018 until March 2019. The findings of this study showed that there were three categories of vague language, namely vague additives to numbers that were realized by approximators and adjectives. The others were vagueness of choice of vague words that were realized by nouns, and vagueness by scalar implicatures that were realized by quantifiers, numbers, and exaggerations. In addition, they also have its functions of vague language. Firstly, giving the right amount of information, it is used since the reporters just shared the right number of information although the exact number was not available. Secondly, filling in lexical gaps of uncertainty, it is used since the reporters wanted to cover the imprecise information with another word, and generalized word that was difficult to identify. Last but not least, self-protection. It is used since the reporters wanted to protect and hedge their statements from imprecise information.Keywords: Vague Language, Categories, News Articles, Disasters, implicature

Early ERP Evidence for Children’s and Adult’s Sensitivity to Scalar Implicatures Triggered by Existential Quantifiers (Some)

How quickly do children and adults interpret scalar lexical items in speech processing? The current study examined interpretation of the scalar terms some vs. all in contexts where either the stronger (some = not all) or the weaker interpretation was permissible (some allows all). Children and adults showed increased negative deflections in brain activity following the word some in some-infelicitous versus some-felicitous contexts. This effect was found as early as 100 ms across central electrode sites (in children), and 300–500 ms across left frontal, fronto-central, and centro-parietal electrode sites (in children and adults). These results strongly suggest that young children (aged between 3 and 4 years) as well as adults quickly have access to the contextually appropriate interpretation of scalar terms.

The interpretations of scalar implicatures, presuppositions, and implicated presupposition by Thai children with autism

Using the negated universal quantifiernot every, the study investigates the interpretations of scalar implicatures, lexical presuppositions, and implicated presuppositions by Thai children with autism spectrum disorders (ASDs; n= 32), comparedto their typically-developing (TD) peers (n= 70) and adults (n= 40). The results provide further empirical evidence to the literature (Chevallier et al. 2010, Hochstein et al. 2017, Pijnacker et al. 2009) that not only do adolescents with ASD perform on par with TD adolescents,children with ASD are also age-appropriate in their performance on deriving scalar implicatures. Despite the children with ASD's ability to compute scalar implicature, they still tend to give more logical, literal responses, compared to their peers. Compared to adults, both children with ASD and TD children still have a higher tendency to rely on the logical meaning rather than pragmatically inferred meaning. They are also less likely than adults to derive scalar implicatures, but equally likely to derive lexical presuppositions. No additive effects of implicated presuppositions are found in any group of the participants.

Priming enrichment in children

Sentences can be enriched by considering what the speaker does not say but could have done. Children, however, struggle to derive one type of such enrichments, scalar implicatures. A popular explanation for this is that they do not know the appropriate alternatives to use to generate the implicature. Namely, children are unaware of the scalar relationship between some and all. We conducted a priming study with N = 72 children, aged 5;1 years, and an adult sample, N = 50, to test this hypothesis. Participants were exposed to prime trials of strong, alternative or weak sentences involving quantifier sentences or ad hoc expressions, and then saw an ambiguous target trial that they could choose to enrich. Consistent with previous studies, children were reluctant to derive implicatures. However, there were two novel findings. (1) Children responded with twice the rate of ad hoc implicature responses than adults, suggesting that the implicature was the developmentally prior interpretation for ad hoc expressions. (2) Children showed robust priming effects, suggesting that children are aware of the scalar relationship between some and all, even if they choose not to derive the implicature.

The Cost of the Epistemic Step: Investigating Scalar Implicatures in Full and Partial Information Contexts

We present the first ERP experiments that test the online processing of the scalar implicature some ⇝ not all in contexts where the speaker competence assumption is violated. Participants observe game scenarios with four open cards on the table and two closed cards outside of the table, while listening to statements made by a virtual player. In the full access context, the player makes a fully informed statement by referring only to the open cards, as cards on the table; in the partial access context, she makes a partially informed statement by referring to the whole set of cards, as cards in the game. If all of the open cards contain a given object X (Fullset condition), then some cards on the table contain Xs is inconsistent with the not all reading, whereas it is unknown whether some cards in the game contain X is consistent with this reading. If only a subset of the open cards contains X (Subset condition), then both utterances are known to be consistent with the not all implicature. Differential effects are observed depending on the quantifier reading adopted by the participant: For those participants who adopt the not all reading in the full access context, but not in the partial access context (weak pragmatic reading), a late posterior negativity effect is observed in the partial access context for the Fullset relative to the Subset condition. This effect is argued to reflect inference-driven context retrieval and monitoring processes related to epistemic reasoning involved in evaluating the competence assumption. By contrast, for participants who adopt the logical interpretation of some (some and possibly all), an N400 effect is observed in the partial access context, when comparing the Subset against the Fullset condition, which is argued to result from the competition between the two quantifying expressions some cards on the table and some cards in the game functioning in the experiment as scalar alternatives.

The Role of Alternatives in Language

In this review we provide a discussion of the concept of alternatives and its role in linguistic and psycholinguistic theorizing in the context of the contributions that have appeared in the Frontiers Research Topic The Role of Alternatives in Language. We are discussing the linguistic phenomena for which alternatives have been argued to play a paramount role: negation, counterfactual sentences, scalar implicatures and exhaustivity, focus, contrastive topics, and sentences with bare plurals and with definite plurals. We review in how far alternatives are relevant for these phenomena and how this relevance has been captured by theoretical linguistic accounts. Regarding processing, we discuss the mental activation of alternatives: its mandatory vs. optional nature, its time course. We also address the methodological issue of how experimental studies operationalize alternatives. Finally, we explore the phenomenon of individual variation, which increasingly attracts attention in linguistics. In sum, this review gives an inclusive and broad discussion of alternatives by bringing together different research strands whose findings and theoretical proposals can advance our knowledge of alternatives in inspiring cross-fertilization.
