When acquiring language, children must not only learn the meanings of words, but also how to interpret them in context. For example, children must learn both the logical semantics of the scalar quantifier some and its pragmatically enriched meaning: ‘some but not all’. Some studies have shown that this “scalar implicature” that some implies ‘some but not all’ poses a challenge even to nine-year-olds, while others find success by age three. We asked whether reports of children’s early successes might be due to the computation of exclusion inferences (like contrast or mutual exclusivity) rather than an ability to compute scalar implicatures. We found that young children (N=214; ages 4;0-7;11) sometimes prefer to compute symmetrical exclusion inferences rather than asymmetric scalar inferences when interpreting quantifiers. This suggests that some apparent successes in computing scalar implicature can actually be explained by less sophisticated exclusion inferences.

AbstractDuring acquisition, children must learn both the meanings of words and how to interpret them in context. For example, children must learn the logical semantics of the scalar quantifier some and its pragmatically enriched meaning: ‘some but not all’. Some studies have shown that ‘scalar implicature’ – that some implies ‘some but not all’ – poses a challenge even to nine-year-olds, while others find success by age three. We asked whether reports of children's successes might be due to the computation of exclusion inferences (like contrast or mutual exclusivity) rather than scalar implicatures. We found that young children (N = 214; ages 4;0–7;11) sometimes compute symmetrical exclusion inferences rather than asymmetric scalar inferences. These data suggest that a stronger burden of evidence is required in studies of implicature; before concluding that children compute implicatures, researchers should first show that children exhibit sensitivity to asymmetric entailment in the task.

Pragmatic Inference

We review experimental evidence regarding the development of scalar implicature in children. Scalar implicatures are inferences that arise when utterances like “Mary ate some of the cakes” are interpreted as “Mary ate some but not all of the cakes.” The evidence suggests that, even though the mechanism for generating scalar implicatures in children is in many respects adult-like, children nevertheless face limitations in computing such conversational inferences from what the speaker said. We highlight the importance of the findings for the development of pragmatic inference, language acquisition, and communication in general. We also identify open questions and promising areas for future research.

When faced with a sentence like "Some of the toys are on the table," adults, but not preschoolers, compute a scalar implicature, taking the sentence to imply that not all the toys are on the table. This paper explores the hypothesis that children fail to compute scalar implicatures because they lack knowledge of the relevant scalar alternatives to words like "some." Four-year-olds were shown pictures in which three out of three objects fit a description (e.g., three animals reading), and were asked to evaluate statements that relied on context-independent alternatives (e.g., knowing that "all" is an alternative to "some" for the utterance "Some of the animals are reading") or contextual alternatives (e.g., knowing that the set of all three visible animals is an alternative to a set of two for the utterance "Only the cat and the dog are reading"). Children failed to reject the false statements containing context-independent scales even when the word "only" was used (e.g., "only some"), but correctly rejected equivalent statements containing contextual alternatives (e.g., "only the cat and dog"). These results support the hypothesis that children’s difficulties with scalar implicature are due to a failure to generate relevant alternatives for specific scales. Consequences for number word learning are also discussed.

Disjunction with two scalar items, such as some or all of the books, has been regarded as evidence for the grammatical theory of scalar implicatures (e.g., Chierchia et al., 2012). Hurford's Constraint (Hurford, 1974) provides that disjuncts are banned from having an entailing relation, and to make such a disjunction comply with Hurford's Constraint, the meaning of some must be locally strengthened. Interestingly, however, the order of disjoined scalar items is not free, as noted by Singh (2008). The order in which a weaker scalar item comes first followed by its stronger scalar mate is better than the other order. I present an analysis of this ordering restriction based on the novel observation that the restriction is not only found in disjunction but in contrastive environments in general. I propose that contrasting a linguistic expression requires a “contrast antecedent,” which must elicit a set of mutually exclusive alternatives that includes the meaning of the contrasted expression. It will be demonstrated how the mutual exclusivity requirement presents a principled explanation for the ordering asymmetry as well as Hurford's Constraint itself, which indicates that the root of the constraint is not in disjunction but in contrastiveness. One of the indispensable ingredients in the proposal is the grammatical/conventional generation of scalar implicatures, as the strengthened meaning must be the basis of alternatives. The paper also provides a speculative analysis of only, in which I suggest that the process of exhaustification in the grammatical theory of scalar implicatures should not be characterized as the implicit only, the semantic contributions of which are more different than commonly assumed.

Stepping backwards in development: integrating developmental speech perception with lexical and phonological development – a commentary on Stoel-Gammon's ‘Relationships between lexical and phonological development in young children’*

Traditional Approaches

Within the subfields of linguistics, traditional approaches tend to examine different phenomena in isolation. As Stoel-Gammon (this issue) correctly states, there is little interaction between the subfields. However, for a more comprehensive understanding of language acquisition in general and, more specifically, lexical and phonological development, we must consider relations between multiple subfields. That is, by examining the interactions between these subfields, a greater understanding of lexical and phonological development can emerge. For instance, the interaction between phonology, syntax and semantics is demonstrated in recent work looking at how phonological patterns can provide a basis for inferring a word's lexical category (such as nouns and verbs) (Christiansen, Onnis & Hockema, 2009; Lany & Saffran, 2010).

Variable Performance

Upon hearing “Some of Michelangelo’s sculptures are in Rome,” adults can easily generate a scalar implicature and infer that the intended meaning of the utterance corresponds to “Some but not all Michelangelo’s sculptures are in Rome.” Comprehension experiments show that preschoolers struggle with this kind of inference until at least 5 years of age. Surprisingly, the few studies having investigated children’s production of scalar expressions like some and all suggest that production is adult-like already in their third year of life. Thus, children’s production of implicatures seems to develop at least 2 years before their comprehension of implicatures. In this paper, we present a novel account of scalar implicature generation in the framework of Bidirectional Optimality Theory: the Asymmetry Account. We show that the production–comprehension asymmetry is predicted to emerge because the comprehension of some requires the hearer to consider the speaker’s perspective, but the production of some does not require the speaker to consider the hearer’s perspective. Hence, children’s comprehension of scalar expressions, but not their production of scalar expressions, is predicted to be related to their theory of mind development. Not possessing fully developed theory of mind abilities yet, children thus have difficulty in comprehending scalar expressions such as some in an adult-like way. Our account also explains why variable performance is found in experimental studies testing children’s ability to generate scalar implicatures; moreover, it describes the differences between children’s and adults’ implicature generation in terms of their ability to recursively apply theory of mind; finally, it sheds new light on the question why the interpretation of numerals does not require implicature generation.

The Relationship

The lessons I have learned over the last many years seem always to come in pairs – a lesson about the findings that brings with it a lesson about life as a researcher...Lesson 1. Even as a doctoral student, I believed that the sorts of social interactions young children had with adults supported language acquisition. In 1971, when I completed my dissertation, that was a minority view, and one ridiculed by many. I was, unfortunately, deflected from a full-on commitment to research on the relationship between social environment and language development for many years by the general atmosphere of disdain for such claims. In the intervening years, of course, evidence to support the claim has accumulated, and now it is generally acknowledged that a large part of the variance among children in language skills can be explained by their language environments. This consensus might have been achieved earlier had I and others been braver about pursuing it.[Download the PDF and read more...]

Methodological Challenges

Long-format speech environment (LFSE) recordings are increasingly used to understand language acquisition among young children (Casillas & Cristia 2019). But in language revitalization, older children are sometimes the largest demographic acquiring a language. In Teotitlán del Valle, Mexico, older children have participated in Zapotec language revitalization workshops since 2017. To better understand how these children use language, and to probe whether the language workshops impact language use, I invited learners to collect LFSE recordings. This study addresses two main questions: (1) what methodological challenges emerge when children ages 6-12 collect LFSE data?; and (2) what do the data suggest about the effects of the Zapotec workshops? I argue that, while creating LFSE recordings with older children presents methodological challenges, the results are useful in highlighting the importance of not only teaching language skills, but of creating spaces where learners are comfortable using the Zapotec language.
