Children's interpretation of negation and quantifier scope in L3 English

AbstractLanguages differ in the preferences for the interpretation of the scope relation between negation and a quantifier. This study investigates the understudied issue of how interpretive preferences associated with a quantifier scope in learners’ L1 and L2 affect their scope interpretations in L3 acquisition. Based on the current models of L3 acquisition, we tested which language, L1 or L2, exerts a stronger effect on the L3 acquisition of quantifier scope. To this end, the study involved two groups of multilingual children (11–13 years old) with different L1s (Chinese or Russian) but with the same L2 (Korean) and L3 (English). The participants completed truth-value judgment tasks designed to investigate their interpretation patterns for English sentences with negation and a quantifier (e.g., Tom did not cut all the trees). The results showed that both groups preferred the L3 interpretation similar to that preferred in their L2, but not in their L1, suggesting a potential L2 influence on L3 acquisition. The study evaluates L3 acquisition theories in light of these results.

Learnability in the acquisition of the English tough construction by L1-Korean adult and child L2 learners

In the English tough construction (TC), knowledge of tough movement is necessary for target performance (the object-interpretation only; e.g. Johni is easy to see ei). The acquisition of the English TC raises a learnability problem for first-language (L1) Korean learners of English as a second language (L2): (1) Korean has no tough movement; (2) no input dictates that the ‘subject interpretation’ is disallowed in the English TC; and (3) no classroom instruction covers the English TC. According to the Fundamental Difference Hypothesis, L2 children – but not L2 adults – can overcome this learnability problem. L1-Korean adult ( n = 49) and child ( n = 30) L2 learners’ (L2ers’) knowledge of the English TC was assessed via a truth-value judgment task manipulating (1) verb transitivity to make the infinitival object gap more vs. less salient and (2) context to avoid vs. strengthen bias toward the (erroneous) subject interpretation. Notably, some high-proficiency adult L2ers showed significantly above-chance performance, despite the error-inducing manipulations, suggesting that adult L2ers can overcome the learnability problem.

Scalar and ad-hoc pragmatic inferences in children: guess which one is easier.

Several studies investigated preschoolers' ability to compute scalar and ad-hoc implicatures, but only one compared children's performance with both kinds of implicature with the same task, a picture selection task. In Experiment 1 (N = 58, age: 4;2-6;0), we first show that the truth value judgment task, traditionally employed to investigate children's pragmatic ability, prompts a rate of pragmatic responses comparable to the picture selection task. In Experiment 2 (N = 141, age: 3;8-9;2) we used the picture selection task to compare scalar and ad-hoc implicatures and linked the ability to derive these implicatures to some cognitive and linguistic measures. We found that four- and five-year-olds children performed better on ad-hoc than on scalar implicatures. Furthermore, we found that morphosyntactic competence was associated with success in both kinds of implicatures, while performance on mental state reasoning was positively associated with success on scalar but not ad-hoc implicatures.

Information structure in language acquisition. Production and comprehension of (in)definite articles by German-speaking children.

The present study investigates the production and comprehension of indefinite and definite articles as markers of givenness by typically-developing German-speaking children, from the perspective of information structure theory. The study involves 93 typically-developing children aged four to seven years old with normal language-skills and 20 adults. The results of a story-narration task and a truth-value judgment task reveal that children have more problems with new than with given referents in production as well as comprehension suggesting a "given better than new"-pattern. These findings are explained in the context of perspective-taking capacities and cue weighting theory.

Are donkey sentences and bare conditionals family or friends?

AbstractThe present study investigates children’s first language acquisition of donkey sentences and bare conditionals in Mandarin Chinese, both of which are concerned with quantification. Kindergarteners, Grade 2 and Grade 4 were recruited for experimental groups, each group consisting of 18 subjects, and 18 adults comprised a control group against which to compare their interpretations. Each subject finished two Truth-Value Judgment tasks, which were sentences in isolation and sentences in context. The results of this research identified a developmental pattern regarding the acquisition of donkey sentences and bare conditionals in Mandarin Chinese. It was found that overall children under seven years of age had difficulty interpreting quantificational sentences. First, concerning the relatedness of the two constructions, all four groups showed a tendency to find donkey sentences easier to interpret than bare conditionals. With respect to contextual effects, by Grade 2, children could obtain adult-like interpretations of donkey sentences in a biasing context, but it was not until they were in Grade 4 that they could interpret both donkey sentences and bare conditionals in their supporting context with adult-like readings. As a result, the subjects’ interpretations were greatly affected by context, but the two constructions were affected in different ways.

Testing children’s knowledge of generic null pronouns

In this paper, I discuss an experiment conducted with children acquiring Brazilian Portuguese (BP) as their native language. The experiment was designed to test if Brazilian children understand that the null subject in impersonal structures has the generic reading in BP instead of the referential one. The experiment consisted of a Truth-Value Judgement Task (TVJT). The results show that children as young as 4 years of age understand the null subject in impersonals as generic. Based on a study showing that a 2-year-old child acquiring Estonian already produces null impersonals (TORN-LEESIK; VIJA, 2012), it is possible that children acquiring BP correctly assign the generic reading to a null pronoun in impersonal constructions before the age of 4. I propose that this knowledge could be tested in children younger than 4 using the Intermodal Preferential-Looking (IPL) paradigm (GOLINKOFF et al.,1987; NAIGLES; TOVAR, 2012), a method more suitable than the TVJT to test children that are very young.----------------------------------------------------------------------------------TESTANDO O CONHECIMENTO DE CRIANÇAS SOBRE PRONOMES GENÉRICOS NULONeste artigo, discuto um experimento conduzido com crianças adquirindo o português brasileiro (PB) como língua materna. O objetivo do experimento era testar se crianças brasileiras entendem que o sujeito nulo em estruturas impessoais tem uma leitura genérica no PB, em vez de referencial. O experimento consistiu em uma Tarefa de Julgamento de Valor de Verdade (TJVV). Os resultados mostram que crianças com 4 anos de idade já interpretam o pronome nulo em impessoais como genérico. Baseado em um estudo que mostra que uma criança de dois anos adquirindo o estoniano já produz sujeitos nulos impessoais, é possível supor que crianças adquirindo o PB atribuam corretamente a leitura genérica ao pronome nulo de impessoais antes dos 4 anos. Proponho que esse conhecimento possa ser testado em crianças antes dessa idade usando o Paradigma do Olhar Preferencial, um método mais adequado do que a TJVV para testar crianças muito novas---Original em inglês.

A within-subjects comparison of the acquisition of quantity-related inferences

This study directly compares quantity inferences from scalar implicatures (‘Some of the ducks are black’) and uniqueness presuppositions in definites (‘the duck is black’) to exhaustivity inferences in English it-clefts (‘It’s the duck that’s black’) for which the theoretical literature disagrees on the source of inference – pragmatic (like scalar implicatures), or semantic (like presuppositions). We investigate whether within-subjects correlations in acquisition can inform us about the source of exhaustivity inferences. Assuming comprehension is achieved once the necessary basis for meaning is acquired, it-clefts should pattern with presupposition judgments if computing a presupposition is involved and should pattern with scalar implicature judgments if computing an implicature is involved. We conduct three experiments to test how closely it-cleft judgments pattern with other quantityrelated inferences, keeping materials maximally similar. The first two experiments test adult participants using a Truth Value Judgment Task and then a 3-point Rating Task; we find that adults’ response patterns to under-informative uses of these constructions differ both across individuals and across inference types, with the Rating Task giving more informative results. In the third experiment, we use the 3-point Rating Task with 4-, 5-, and 6- year olds to characterize response patterns across the three inference types for each individual subject. We find that the individual response patterns children exhibit are consistent with the theory that it-cleft exhaustivity shares an underlying cognitive source with the computation of presupposition inferences, but not with scalar implicature inferences.

Do All Eagles Fly High? The Generic Overgeneralization Effect: The Impact of Fillers in Truth Value Judgment Tasks

Abstract The generic overgeneralization effect is an attested tendency to accept false universal generalizations such as “all eagles fly” or “all snakes lay eggs” as true. In this paper, we discuss the generic overgeneralization effect demonstrated by Polish adult speakers. We asked 313 native speakers of Polish to evaluate universal quantified generalizations such as “all eagles fly” or “all snakes lay eggs” as true or false. The control group of 107 respondents provided data on the acceptance rates of the corresponding generic generalizations such as “eagles fly” or “snakes lay eggs”. By determining the impact of test fillers on the participants’ acceptance rates, the study aimed to identify the scope of the generic overgeneralization effect. We manipulated four conditions: the universal negative, positive, neutral, and generic control conditions. The results showed significant differences between the first two conditions, but neither the negative nor the positive condition differed from the neutral one. The overall acceptance rates of universal statements were 63% for the negative condition, 49% for the positive condition, 55% for the neutral condition, and 90% for the control group. Overall, the participants accepted universal quantified statements at high rates even when they were prompted to reject them. The results may be interpreted as another piece of evidence in support of the generic overgeneralization effect.

The syntax of Korean VP anaphora: an experimental investigation

The Korean VP anaphor (VPA) kuleha or kulay ‘do so’ has often been argued to involve ellipsis of an articulated VP structure, which is replaced with the surface form at PF (e.g., Cho in Lang Res 32:621–636, 1996; Ha in Korean J Linguist 35:471–487, 2010; Park in Linguist Res 32:693–718, 2015). In this paper, we present empirical data that does not support such a characterization, obtained from two experimental studies designed to diagnose the presence of “hidden” syntactic structure. In Experiment 1, building upon Kim and Han’s (in: Grosz, Patel-Grosz (eds) The impact of pronominal form on interpretation. Mouton de Gruyter, Berlin, pp 349–373, 2016) finding that quantificational binding of the Korean pronoun ku ‘he’ is subject to inter-speaker variation, we conducted a truth-value judgment task experiment to examine the (un)acceptability of sloppy identity interpretation in the VPA construction. If the VPA is indeed derived from the deletion of an articulated VP, and thus has an unpronounced internal structure to house ku, the distributions of the sloppy reading of ku and the quantificational binding of ku should be correlated across the sampled population; however, such a pattern was not found. In Experiment 2, we conducted a Likert scale rating experiment testing whether extraction out of the VPA site is possible. If the VPA is an instance of ellipsis, extraction from the VPA site should be possible since there would be a syntactic structure that hosts an extractable constituent. This prediction, however, was not confirmed. On the basis of these empirical findings, we argue that Korean VP anaphora are base-generated pro-forms (Bae and Kim in Stud Mod Gramm 70:49–71, 2012; Park in Stud Mod Gramm 72:41–66, 2013), and retrieve their semantic values from the context through interpretive rules (Hoji in Linguist Inq 29:127–152, 1998; Hoji, in: Barss (ed) Anaphora: a reference guide. Blackwell Publishing, Oxford, pp 172–236, 2003), as in the case of pronominal resolution.

A ‘no’ with a trace of ‘yes’: A mouse-tracking study of negative sentence processing

There is strong evidence that comprehenders can parse sentences in an incremental fashion. However, when the sentence contains a negation, the evidence is less clear. Previous work has shown that increasing the pragmatic felicity of a negative sentence reduces or eliminates any processing overhead relative to affirmative sentences. However, in previous work felicity has gone hand-in-hand with the predictability of critical material in a sentence. In three experiments reported here, we presented equally felicitous sentences with critical material of varying predictability (operationalised as the number of possible completions) to test whether this might be a critical factor determining the ease with which partial sentences containing a negation are interpreted. Participants completed a truth-value judgement task (Experiment 1) or a sentence completion task (Experiments 2 and 3) after viewing a visual environment that provided the context for a test sentence, which could differ in truth value (in Experiment 1 only), polarity (affirmative or negative), and number of possible completions (one, two, or three). In all three experiments, we recorded response times and accuracy, but also response dynamics via participants’ computer mouse trajectories, allowing us to test specific hypotheses about the time course of comprehension. Across all experiments, in conditions with one or two possible targets, we observed consistent detrimental effects of negative polarity, suggesting that the difficulty in processing negation cannot be reduced to effects relating to predictability or pragmatic felicity. We discuss this finding in relation to incremental and two-stage models of processing and outline a new account of the processing difficulty arising from negation in terms of a conflict between what is locally activated on the basis of individual words and phrases and the global meaning of a negative sentence.

Acquisition of aspect in L2: The computation of event completion by Japanese learners of English

AbstractPrevious studies on the acquisition of semantics in the aspectual domain have suggested that a difficult case for achieving a targetlike representation in a second language arises when learners need to preempt a first language (L1) option (Gabriele, 2009). This study investigates this issue by focusing on a learning scenario where predicate-level variability exists in the L1 input. We investigate whether Japanese learners of English can learn to invalidate event cancellation readings (Tsujimura, 2003) in English and how such knowledge develops with increasing English proficiency. We address these questions by examining how Japanese learners of English interpret accomplishment predicates that allow an event cancellation reading in Japanese but not in English. A truth-value judgment task was administered to 60 beginner, 96 intermediate, and 40 advanced Japanese learners of English as well as 20 L1 English and 20 L1 Japanese speakers. Our results showed that Japanese learners of English progressed toward a targetlike representation of aspectual entailment. We argue that such progress follows two parallel routes: a grammatical route rooted in the learners’ growing awareness of the English determiner and number morphology combined with a statistical route rooted in the learners’ inferences based on missing data.

Reverse transfer of L3 on the Interpretation of L2 Reflexives

English reflexives allow only for short-distance binding except for exempt anaphors, while Chinese and Korean reflexives can be both short- and long-distance bound. This study examines the cross-linguistic influence of L3 Korean on L2 English in the interpretation of reflexive bindings with Chinese and Korean participants. 30 Chinese-English (CE), 20 Korean-English (KE), and 23 Chinese-English-Korean (CEK) participants completed an English proficiency test and a Truth Value Judgment Task (TVJT). The results of proficiency test showed KE scored significantly higher than CE and CEK, while the latter two were comparable. Nevertheless, although the mean scores of TVJT revealed marginally significant variance, Post-hoc comparisons showed KE scored significantly higher than CE, but not than CEK. CEK displayed numerically higher score than CE, though not significantly. The findings mirrored the pattern in Ahn & Jang (2019) in that L3 seemed to play a more robust role in L2 acquisition. The variation in TVJT between CE and CEK was unlikely to be introduced by either L1or L2 proficiency. Aligning with the Foreign Language Effect Model, L2 may be changed to reflect patterns in L3 when a specific feature was not common for both languages.

Effects of the interface categories on the acquisition patterns of English reflexives among learners of English as a foreign language

Objectives: Binding properties are difficult for learners to fully acquire. This study explored English-as-a-foreign-language learners’ acquisition patterns of the three binding properties of English reflexives and the effectiveness of the Interface Hypothesis. Methodology: One hundred and twenty-two native speakers of Chinese, a language with different binding properties, participated in the study; they were categorized into low, intermediate and advanced groups according to an English proficiency test. They were read 32 stories of 2 to 5 sentences each and were required to provide a comment sentence instantiating the three binding properties; i.e. c-command, subject orientation and locality. Data and analysis: A mixed repeated measures ANOVA was conducted with group and individual results of the experimental task to ascertain whether there were significant differences across different binding properties and among the three proficiency groups. Findings: Results from a truth-value judgment task indicate that the within-groups difficulty order of the three distinct binding properties is that: (a) for the low-proficiency group, c-command was easier than locality and orientation; and (b) for the intermediate-proficiency and the high-proficiency groups, c-command was easier than locality which, in turn, was easier than orientation. Among the three proficiency-groups, four acquisition patterns were found, which standard Binding Theory and its extensions cannot adequately explain. Originality: This is the first study to provide a variable-dependent account. It is argued that success or failure in establishing interface relations in second language grammars is likely to depend on a number of variables, including the involvement of the syntax–lexicon interface, syntax–semantics interface and syntax–discourse interface. Implications: The research suggests that the acquisition of English reflexives is variable-dependent, but not domain-wide. Specifically, the relationship between the binder and anaphoric expression can be established between the anaphors and some of their potential antecedents in second language English grammars, but not others, lending support to the Interface Hypothesis.

영어 초점사 only의 중의성에 대한 한국인 영어 학습자의 이해 선호도에 관한 연구

This study examines Korean EFL learners’ interpretations of ambiguous focuses in sentences with preverbal only (e.g., Max only carries the stones). Ambiguous sentences containing preverbal only are known to evoke three possible meanings depending on which of the following its scope is assigned to: a noun phrase (NP) as a direct object, a verb (V) or a verb phrase (VP). To investigate which default meaning is preferred in the comprehension of preverbal only, forty four Korean EFL learners and ten native English speakers participated in the study using a sentence completion task which differed from a picture-based Truth-value Judgment Task used in previous studies. Participants were asked to read a background story followed by a sentence with preverbal only and then fill in the blank in a following sentence with NP, V or VP contrast information depending on their preferred interpretation. As a result, Korean EFL learners as well as native English speakers were found to prefer the NP-focused interpretation as the default meaning. These results are discussed in relation to methodological issues and sentence processing principles.

When OR is assigned a conjunctive inference in child language

ABSTRACTIt has been proposed that children differ from adults in that children license a conjunctive inference to disjunctive sentences that lack any licensing expression. The proposal is that children infer “A and B” from sentences of the form “A or B.” Although children’s conjunctive interpretations of disjunction have been reported in some studies, they have not been observed in other studies. This study investigates one possible source of the different findings, which is the presence or absence of objects that are contextually introduced, beyond those mentioned in the test sentences. Using a Truth Value Judgment Task, we conducted three experiments with preschool Mandarin-speaking children and a control group of adults. Test sentences in Experiment 1 included disjunction and a deontic modal verb, and the contexts only included objects that were mentioned in the test sentences. In Experiment 2, the deontic modal verb was omitted from the test sentences. Experiment 3 presented the same sentences as Experiment 2, but the contexts included additional objects beyond those mentioned in the test sentences. Both children and adults assigned a conjunctive inference to the test sentences in Experiment 1. In Experiment 2, with no deontic verbs and no contextually introduced objects, a subset of children computed conjunctive inferences, whereas none of the adults did. In Experiment 3, neither group made a conjunctive inference. The findings reveal that entities in nonlinguistic contexts influence children’s understanding of logical expressions. Moreover, preschool children already have linguistic knowledge that modal verbs license conjunctive inferences for sentences with disjunction.

Relations between verb factivity and first-order and second-order false belief understanding: Evidence from Mandarin-speaking typically developing children and children with autism spectrum disorders

ABSTRACT Previous studies have shown that factivity is closely related to first-order false belief (FB). However, whether the role of factivity in first-order FB extends to second-order FB remains unclear. Investigations of verb factivity and second-order FB would contribute to our knowledge of the role of language in theory of mind (ToM) development. This study examined relations between verb factivity and first-order and second-order FB reasoning in 156 four- to seven-year-old typically developing (TD) Mandarin-speaking children, and in 17 children with autism spectrum disorders (ASD) and 17 TD matched controls. Children’s understanding of a factive zhīdào ‘know’, a non-factive juédé ‘think’ and a counter-factive jiǎzhuāng ‘pretend’ was assessed by a truth value judgement task. For TD children, zhīdào ‘know’ (factive) significantly predicted their first-order and second-order FB performances, and jiǎzhuāng ‘pretend’ (counter-factive) significantly predicted their first-order FB performance. For autistic children, they performed significantly poorer than their TD counterparts on complementation, verb factivity, first-order and second-order FB, and their first-order FB performance was significantly related to jiǎzhuāng ‘pretend’ (counter-factive). The findings suggest that verb factivity relates to both first-order and second-order FB, and verbs differing in factuality and mental state status contribute differently to ToM development.

The Role of L3 in the Interpretation of Articles with Definite Plurals in L2 English

Recent developments in the acquisition of third languages (L3A) have only placed an emphasis on the influence of L1 or L2 on L3A (forward transfer). However, this study investigated the role of L1 or L3 in L2A (backward transfer), by focusing on cross-linguistic variations in generic interpretation on plural NPs. We examined how multilingual (L2 and L3) learners interpret nominals in generic contexts. Two experiments (an acceptability judgement task and a truth value judgement task) are conducted to investigate the influence of L1 and L3 on L2A (English) by third language (L3) learners. We looked at whether these learners exhibit backward transfer in the acquisition of generic NPs in English. The results of the two experiments suggest that the influence of L3 is more significant in L2A of English than that of L1. Therefore, in terms of backward transfer, the results are more supportive of the Foreign Language Effect which implies that cognitive similarities play an important role in L2A for L3 learners. In conclusion, for those multilinguals, it is important to factor the L3 (high foreignness) influence when acquiring L2 (high foreignness) because L3 transfer is more important than L1 (non-foreign) transfer.

Linking Hypothesis and Number of Response Options Modulate Inferred Scalar Implicature Rate.

The past 15 years have seen increasing experimental investigations of core pragmatic questions in the ever more active and lively field of experimental pragmatics. Within experimental pragmatics, many of the core questions have relied on the operationalization of the theoretical notion of “implicature rate.” Implicature rate based results have informed the work on acquisition, online processing, and scalar diversity, inter alia. Implicature rate has typically been quantified as the proportion of “pragmatic” judgments in two-alternative forced choice truth value judgment tasks. Despite its theoretical importance, this linking hypothesis from implicature rate to behavioral responses has never been extensively tested. Here we show that two factors dramatically affect the “implicature rate” inferred from truth value judgment tasks: (a) the number of responses provided to participants; and (b) the linking hypothesis about what constitutes a “pragmatic” judgment. We argue that it is time for the field of experimental pragmatics to engage more seriously with its foundational assumptions about how theoretical notions map onto behaviorally measurable quantities, and present a sketch of an alternative linking hypothesis that derives behavior in truth value judgment tasks from probabilistic utterance expectations.

Co-speech gesture projection: Evidence from inferential judgments

The nature of the semantic contribution of co-speech gestures has been the subject of recent theoretical and experimental investigation. Such gestures have been reported to give rise to cosuppositional inferences that can project out of certain linguistic environments, much in the way that presuppositions of verbal expressions do (Schlenker 2018a; b). For example, a sentence like “John will not [use the stairs]_UP”, produced with a finger pointed upwards while pronouncing the verb phrase, is argued to give rise to the inference that if John were to use the stairs, he would go up the stairs. Tieu et al. (2017) investigated the projection properties of directional inferences associated with the gestures UP and DOWN, using a Truth Value Judgment Task and a Picture Selection Task, and reported the presence of existential projection of the gestural inferences out of quantified environments. We investigated the same gestural inferences using a method that more closely tracks the introspective judgments reported in the literature on gesture projection. Participants were presented with an Inferential Judgment Task, in which they had to rate the strength of inferences arising from UP and DOWN in six different linguistic environments. Using this task, we observed projection of the conditional inference from the scope of negation and universal projection of the inference from the scope of “none” and “exactly one”, as well as suggestive evidence that the inference can be locally accommodated in the scope of negation and “none.” These main findings would be difficult to explain if gestures were posited to make at-issue contributions; the finding of local accommodation is also not straightforwardly explained on the view that co-speech gestures contribute supplement-like meanings (Ebert & Ebert 2014). On the other hand, both main findings are compatible with the view that co-speech gestures trigger cosuppositions.

The acquisition of object movement in Dutch: L1 transfer and near-native grammars at the syntax–discourse interface

This article investigates near-native grammars at the syntax–discourse interface by examining the second language (L2) acquisition of two different domains of object movement in Dutch, which exhibit syntax–discourse or syntax–semantics level properties. English and German near-native speakers of Dutch, where German but not English allows the same mapping strategies as Dutch in the phenomena under investigation, are tested on two felicity judgment tasks and a truth value judgment task. The results from the English participants show sensitivity to discourse information on the acceptability of non-canonical word orders, but only when the relevant discourse cues are sufficiently salient in the input. The acquisition of semantic effects on object movement was native-like for a large subset of the participants. The German group performed on target in all experiments. The results are partially in line with previous studies reporting L2 convergence at the syntax–discourse interface, but suggest that input effects should also be taken into account. Furthermore, the differences between the first language (L1) English and the L1 German group suggests that non-target performance at the syntax–discourse interface is not caused by general bilingual difficulties in integrating discourse information into syntax. The article elaborates on factors that contribute to (in)complete acquisition at the syntax–discourse interface.
