Investigating the role of case markers in honorific agreement processing in Korean

This study explores the influence of case markers on the attraction effect in subject-verb honorific agreement in Korean. Using a self-paced reading experiment on PCIbex Farm, we manipulated case markers (possessive vs. nominative) and the presence of the honorific marker -si on verbs to assess their impact on the attraction effect, where syntactically illicit NPs are erroneously retrieved due to partial feature matching. While Avetisyan et al. (2020) reported that in Armenian, case information is used as a retrieval cue during subject-verb number agreement, our preliminary findings reveal no significant attraction effect related to case marker similarity, indicating that the case features (nominative case) do not crucially trigger the attraction effect in honorific agreement. The discrepancy with previous studies highlights the role of noun animacy and the specific construction of Korean sentence structure. Our results contribute to understanding the nuanced factors influencing honorific agreement processing in Korean and suggest that case marking, while integral to sentence structure, does not significantly affect the attraction effect in honorific agreement processing.

The spontaneous activities of the multiple demand network are related to individual differences in indirect replies comprehension

This study aims to investigate the brain networks engaged in the comprehension of indirect language, as well as the individual difference in this capacity. Specially, we aim to determine whether the difference is solely influenced by the difference in individuals’ default network (DN)/language network or whether it also relies on the networks associated with processing of complex cognitive tasks, particularly the multiple demand network (MDN). Conversational indirectness scale (CIS) scores in the interpretation dimension were used as a behavioral indicator of the indirect comprehension tendency. Reading time difference between indirect replies and direct replies collected through a self-paced reading experiment was deemed as a behavioral indicator of comprehension speed of indirect replies comprehension. The two behavioral indicators were combined with resting-state functional magnetic resonance imaging (rs-fMRI). The behaviour-rfMRI analysis showed that ALFF value of right SPL and the functional connectivity (FC) between the right SPL and right IPL/SMA/ITG/Precuneus/bilateral IFG were positively correlated with the interpretation dimension of CIS scores. In addition, the ALFF value of right fusiform gyrus, the FC between the right fusiform gyrus and right precuneus, and the FCs between right SPL and right IPL/Precuneus/IFG were negatively correlated with indirect replies comprehension speed. Overlapping of these regions with large-scale brain network revealed that the right SPL was mainly located in the MDN, and the right fusiform gyrus was mainly located in the language network. Additionally, the areas showing functional connectivity with these regions were primarily located in the MDN, with a smaller subset located in the DN. Our findings suggest that the ability of individuals to actively and rapidly acquire indirect meaning relies not only on the support of the DN and the language network, but also requires collective support from the MDN.

Agreement attraction in grammatical sentences and the role of the task

This study evaluates two broad classes of language processing accounts that make predictions for sentences like “The admirer of the singer(s) apparently thinks...”. Feature distortion accounts predict increased processing difficulty at the verb in sentences with a plural distractor noun (singers) while similarity-based interference accounts predict the opposite: increased difficulty in sentences with a singular distractor noun (singer). Neither of these effects was reliably observed in earlier research, and the Bayesian meta-analysis of 31 published studies reported here is almost perfectly inconclusive. An explanation may be that both effects occur simultaneously and therefore mask each other. To test this idea, we conducted three single-trial self-paced reading experiments (N1=4,296, N2=3,920, N3=3,559) which orthogonally manipulated agreement attraction and inhibitory interference. Surprisingly, all three experiments produced evidence for agreement attraction but none for inhibitory interference, which supports feature distortion but not similarity-based interference accounts. Experiment 4 (N4=3,535) tested the role of the expected task by preparing participants for a comprehension question (vs. acceptability judgment in Experiments 1–3). It showed neither agreement attraction nor inhibitory interference effects. Our findings demonstrate that agreement attraction effects can arise in grammatical sentences – contra earlier research – but also that these effects crucially depend on the task. This explains inconsistent results in prior research and supports feature distortion as the driving force behind attraction effects in grammatical sentences.

The processing of Russian Idioms in Heritage Russian Speakers and L2 Russian Learners

The use of idioms differentiates native speakers (NSs) from second language (L2) learners, whereas the use of idioms by heritage speakers (HSs) might resemble both groups at the same time. This study examines the processing of idioms in heritage Russian speakers (N = 16) and L2 Russian learners (N = 16), comparing them to Russian native speakers as a control group (N = 23). Heritage speakers acquire Russian similarly to the first language acquisition in their family. This enables them to have a more natural approach to language than L2 learners. However, heritage speakers are also similar to L2 learners since their Russian language competence is still not native-like due to insufficient language input. To test whether idiom processing in HSs resembles that of L2 learners or rather in NSs, we conducted a self-paced reading experiment. The idioms were divided into three categories based on the cross-language influence factor: having full English equivalents, semi-equivalents, or no-equivalents. Our findings show no significant difference in idiom processing in HSs and L2 learners, whereas their processing significantly differed from that by NSs of Russian. Also, we found different processing for full and semi-equivalent idioms (in the HS and L2 groups). Full and no-equivalent idioms were also processed differently in all the three groups.

The representation of agreement features in memory is updated during sentence processing: Evidence from verb-reflexive interactions

The formation of linguistic dependencies is subject to memory interference. In this study, we ask whether memory representations are fixed, or whether they can be distorted and updated after their initial encoding. Models of Cue-Based Retrieval assume that memory representations are fixed. However, representational interference and rational inference models assume that memory contents can be edited. To examine this, we test how reflexive attraction is affected by preceding verbal agreement in Hebrew. Cue-Based Retrieval suggests that agreement on the verb can exaggerate the reflexive’s sensitivity to the distractor. In contrast, we propose that if memory representations can be edited, verbal agreement can alter the representation of the subject. This process would reduce vulnerability to distortions originating from the distractor. In two self-paced reading experiments and one forced-choice completion we find (i) decreased reflexive attraction when (grammatical or ungrammatical) agreement cues were available on the preceding verb; and (ii) a preference for reflexive forms matching the verb over forms matching the subject when the sentence included ungrammatical verbal agreement. These results suggest that comprehenders use featural information from the verb to recover properties of the subject. The findings are therefore consistent with a memory model where representations can be distorted and updated, as well as with rational inference about memory disruption.

Vulnerability in processing definiteness: The case of heritage Turkish.

Definiteness has been argued to be difficult for language learners to acquire because the correct usage of definiteness requires the integration of external interfaces that involve linguistic and non-linguistic information. Previous offline studies with heritage speakers have constantly reported difficulties in the use of pragmatically appropriate definite forms. The current study aims to investigate the processing of definiteness in Turkish heritage speakers via a self-paced reading experiment and to compare heritage speakers' reading times and end-of-sentence acceptance percentage to monolingually-raised Turkish speakers. The results of the experiment indicate significant differences between the heritage and monolingually-raised Turkish speakers only in the end-of-sentence acceptance percentage data but not in the reading time data. This difference between the two groups suggests that Turkish heritage speakers perform differently from the monolingually-raised Turkish speakers only in indefinite-specific sentences when they have to use their metalinguistic knowledge. These results show that heritage speakers experience vulnerability/difficulty when they have to integrate external interfaces in indefinite-specific sentences but not in definite-specific sentences.

Transitivity and non-uniform subjecthood in agreement attraction.

Research on human language converges on a view in which a grammatical "subject" is the most saliently encoded entity in mental representation. However, subjecthood is not a syntactically uniform phenomenon. Notably, many languages encode morphological distinctions between subjects of transitive verbs (i.e., verbs that require an object) and subjects of intransitive verbs. We ask how this typological pattern manifests in a language like English (which does not morphologically signal it) by examining the "distinctiveness" of transitive versus intransitive subjects in memory during online sentence processing. We conducted a self-paced reading experiment that tested for "attraction" effects (Dillon et al., Journal of Memory and Language, 69(2), 85-103, 2013; Wagers et al., Journal of Memory and Language, 61, 206-237, 2009) in the processing of subject-verb number agreement. We find that transitive subjects trigger attraction effects, but that these effects are mitigated for intransitive subject attractors (independently of the number of other noun phrases present in the intervening clause). We interpret this as indicating that transitive subjects are less distinctive and therefore less representationally salient than intransitive subjects: This is because a transitive subject must compete with another clause-mate core argument (i.e., a direct object), which draws on resources from the same pool of memory resources. On the other hand, an intransitive subject minimally only competes with a non-core argument (i.e., an oblique noun phrase); this consumes fewer memory resources, leaving the subject to enjoy greater spoils.

Pre-verb reactivation of arguments in sentence processing

Major models of sentence comprehension assume that a verb triggers retrieval of preceding thematic arguments from memory to establish argument-verb dependencies. If so, longer argument-verb distance should lead to higher processing load at the verb (a locality effect),since the representation of the argument should suffer from decay and/or interference.However, verb-final languages have often failed to show the expected argument-verb locality effect. A possible account of the lack of the effect is that arguments and adjuncts before the verb reactivate each other, counteracting memory degradation. In a pair of self-paced reading experiments in Japanese, a verb-final language, we found evidence of such pre-verb reactivation.Specifically, there was a locality effect and a similarity-based interference effect at the head of the adverbial that follows the subject, both of which suggest the retrieval of the subject at that point. The results are difficult to accommodate with other accounts of the lack of locality effect, such as a confounding effect of expectation and the inherent locality-insensitivity of verb-final languages. It is further argued that the constructivist analysis of verbal argument structure, which has been developed in generative syntax, provides an explanation for why such pre-verb reactivation takes place. 

Does the processing advantage of formulaic language persist in its nonadjacent forms? Evidence from Chinese collocation processing in children

Recent studies have accumulated to suggest that children, akin to adults, exhibit a processing advantage for formulaic language (e.g. save energy) over novel language (e.g. sell energy), as well as sensitivity to phrase frequencies. The majority of these studies are based on formulaic sequences in their canonical form. In natural language use, however, many formulaic sequences, collocations in particular, can be modified with words intervening in between the individual constituents (e.g. save energy → save all forms of energy). For some collocations, their nonadjacent forms are equally, and even more frequently used than their adjacent form. Despite this, it remains almost unknown whether the processing advantage and sensitivity to phrase frequencies persist in nonadjacent collocations in children. Based on reading times in a self-paced reading experiment, the current study found that two age groups – third and sixth graders – exhibited a processing advantage for Chinese collocations and sensitivity to phrase frequencies, with two and even four Chinese characters inserted in the middle. The persistence of processing advantage and sensitivity was affected by insertion length as well as age. These results are in line with a usage-based theoretical approach to language learning, processing and use.

Discourse coherence modulates use of predictive processing during sentence comprehension

Context has been shown to be vitally important for comprehension. Lexical processing is facilitated when words are highly predictable given their local sentence context, suggesting that people pre-activate likely upcoming words to aid comprehension. However, this facilitation is affected by knowledge about the global context in which comprehension takes place: people predict less when in an environment where expectations are frequently violated. The current study investigated whether discourse coherence is an additional cue that comprehenders use to modulate lexical prediction. In a series of online, self-paced reading experiments, participants read target sentences preceded by short contextual preambles. Local facilitation effects were manipulated through the cloze probability of a critical word within the target sentence and discourse coherence was manipulated by varying the degree to which the target sentence was consistent with the information presented in the preamble. In the first two experiments, target sentences were read more slowly when they occurred in less coherent discourses, but no local facilitation effects were observed. In the third experiment, we strengthened the predictability manipulation by using semantically anomalous critical words. In this experiment, predictable words were processed more quickly and anomalous words more slowly when they occurred in highly coherent discourse. Our results suggest that comprehenders are sensitive to shifts in the topic of discourse and that they downregulate predictive processing when they encounter incoherence in the discourse. This is consistent with recent theoretical accounts suggesting that comprehenders flexibly engage in predictive processing, pre-activating semantic and lexical information less when their expectations are less likely to be reliable.

Non-gendered pronoun processing: an investigation of the gender non-specific third person singular pronoun ‘TA’ in Chinese

ABSTRACT This study investigated the processing of the Chinese nongendered third-person singular pronoun, “TA,” in a series of self-paced reading experiments. We begin by investigating the perceived appropriateness of TA using a novel implementation of the modified maze task. We then contrasted reading latencies for TA and male- and female-gender pronouns in reference to antecedents with varying stereotypical gender (e.g., occupation terms) and definitional gender (e.g., kinship terms). In our analysis, we assessed several means of operationalizing stereotypical gender information. Optimal model performance was achieved with a continuous measure that accounted for individual differences in gender perception, suggesting the involvement of a probabilistic component. Results for reading latencies and perceived appropriateness of TA support previous findings from discourse analysis that TA is not entirely gender-neutral but rather has nuanced contexts of use in modern Chinese written discourse.

Functional priority of syntax over semantics in Chinese ‘ba’ construction: evidence from eye-tracking during natural reading

Abstract Studies on sentence processing in inflectional languages support that syntactic structure building functionally precedes semantic processing. Conversely, most EEG studies of Chinese sentence processing do not support the priority of syntax. One possible explanation is that the Chinese language lacks morphological inflections. Another explanation may be that the presentation of separate sentence components on individual screens in EEG studies disrupts syntactic framework construction during sentence reading. The present study investigated this explanation using a self-paced reading experiment mimicking rapid serial visual presentation in EEG studies and an eye-tracking experiment reflecting natural reading. In both experiments, Chinese ‘ba’ sentences were presented to Chinese young adults in four conditions that differed across the dimensions of syntactic and semantic congruency. Evidence supporting the functional priority of syntax over semantics was limited to only the natural reading context, in which syntactic violations blocked the processing of semantics. Additionally, we observed a later stage of integrating plausible semantics with a failed syntax. Together, our findings extend the functional priority of syntax to the Chinese language and highlight the importance of adopting more ecologically valid methods when investigating sentence reading.

Online revision process in clause-boundary garden-path sentences.

A long-standing question in sentence processing research concerns the online parsing process in clause-boundary garden-path sentences, such as After Mary dressed John bathed. In this sentence, "John" must be parsed as the matrix subject DP but can be locally analysed as the object of the embedded verb. There is considerable evidence that the parser misanalyses these garden-path sentences. However, the controversy lies in whether the parser revises them during the online parsing process. The present study investigated this revision process through two self-paced reading experiments utilising grammatical constraints on reflexives and subject or object relative clauses embedded within the locally ambiguous DP. The results provided evidence of revision when a subject relative clause was embedded but not when an object relative clause was embedded. These findings suggest that the parser assigns grammatical structures that correspond to input strings during the revision of clause-boundary ambiguities but that object relative clauses affect the online revision process.

Garden-path sentences and the diversity of their (mis)representations.

Previous studies have reliably shown that the initial misanalysis of garden-path sentences lingers even after the whole sentence is processed. However, other aspects of the resulting representation of these sentences are far from being clear. Some authors argue that comprehenders form a full analysis of the sentence which is faithful to the input and that the fact that the misanalysis lingers is due to an inhibition failure. Recently, it has been shown that comprehenders might not manage to create a coherent representation at all, at least in the case of more demanding garden-path structures. The aim of the current paper is to examine resulting representations of garden-path sentences in more detail. To do this, four self-paced reading experiments in Czech were conducted, which differed in the presentation mode (word-by-word and sentence-at-once) and comprehension question format (yes-no questions and open-ended questions). The experiments replicated effects typical for the lingering initial misanalysis, but provided mixed evidence for other aspects of resulting representations. In most cases, participants managed to build a coherent representation that was faithful to the input. However, both the quantitative and qualitative analysis of the results showed that comprehenders sometimes maintained multiple local interpretations at once or even failed to build a coherent representation of a garden-path sentence. Thus, we argue that resulting representations of garden-path sentences are in fact not uniform, but rather diverse, and they vary both in their faithfulness to the presented input and in their internal coherence.

Illusions of plausibility in adjuncts and co-ordination

ABSTRACT Illusions of grammaticality, where ungrammatical sentences are misperceived as grammatical (e.g. The key to the cabinets were rusty), have been widely studied during language comprehension. Such grammatical illusions have been influential in debate surrounding so-called representational and retrieval-based accounts of linguistic dependency resolution. Whether analogous illusions of plausibility occur at the level of semantic interpretation has only recently begun to be examined, and thus far, these illusions have been restricted to a narrow range of linguistic phenomena. In two eye-tracking during reading experiments (n = 48 in each) and two self-paced reading experiments (n = 192 in each) we examined the possibility of semantic illusions during the processing of adjuncts and co-ordination. Across experiments, our results suggest illusions of plausibility during dependency resolution, though interference effects were clearer in adjuncts than co-ordination. We argue that our findings are more compatible with retrieval-based rather than representational accounts of linguistic dependency resolution.

Metaphor processing: Referring and predicating

The general consensus emerging from decades of empirical investigation of metaphor processing is that, when appropriately contextualised, metaphorically used language is no more demanding of processing effort than literally used language. However, there is a small number of studies which contradict this position, notably Noveck, Bianco, and Castry (2001): they maintain that relevance-based pragmatic theory predicts increased cognitive costs incurred in deriving the extra effects that metaphors typically yield, and they provide experimental results that support this prediction. In our study, we first surveyed and assessed the tasks and stimulus materials of many experiments on metaphor processing from the 1970's to the present day. The most telling result was an apparent disparity between the processing of metaphorical language used predicatively versus referentially. We then ran two self-paced reading experiments to test our hypothesis that when used as a predicate, metaphorical language is no more costly than literal language, but when used referentially, it does incur extra costs, even given a preceding biasing context. In the first experiment, all metaphorical referring expressions were in subject position so occurred early in the sentence; in the second experiment, we controlled for any effect of sentence position by placing metaphorical referring expressions in object position, thus later in the sentence, similar to the predicate metaphors. In both cases, metaphorical referring incurred significantly greater costs relative to literal equivalents than did metaphorical predication, with no effect of sentence position. We end with a brief analysis of why the referential use of metaphor is special and effort-demanding.

(Reversed) Mismatch Asymmetry in English Subject-Verb Agreement

This paper investigates, in English, the widely reported mismatch asymmetry, or plural attraction in the production of subject-verb agreement and the relatively less observed reversed mismatch asymmetry, or singular attraction in comprehension. Through a self-paced reading experiment, a read-aloud production task and a pen-and-paper questionnaire, we examined whether singular attraction is a genuine effect in comprehension or it could be due to the experimental materials in the few studies that reported it. The results support the view that singular attraction in comprehension is genuine, at least for structures that include three nouns in the subject, and plural attraction extends to sentences with complex subjects that include three nouns when the task is not too demanding. The (reversed) mismatch asymmetry in subject-verb agreement is attributed to the differential mechanisms involved in sentence comprehension and production.

Sensitivity to syntactic dependency formation in child second language processing: a study of numeral quantifiers in Korean

AbstractThis study investigates whether child second language (L2) learners can use syntactic information during the processing of sentences involving unbounded dependencies and how their processing patterns compare to those of child monolinguals and adult L2 learners. Through a self-paced reading experiment involving the numeral quantifier (NQ) construction in Korean, we tested participants’ sensitivity to agreement violations between a noun phrase (NP) and an NQ in local and nonlocal conditions. The results showed that a subset of child L2 learners who demonstrated target-like knowledge of NP-NQ agreement in an offline task spent a longer processing time in the NP-NQ mismatch than in the NP-NQ match condition, in both local and nonlocal contexts. These child L2 learners’ processing patterns were comparable to those observed in child monolinguals and adult L2 learners. These findings suggest that child and adult L2 learners rely on the same system of syntactic representations and processing mechanisms that guide first language processing.

Locus and timing of gender resolution: Probes, goals and predictions

Two lines of theoretical research have dominated the question of the locus of gender resolution in the context of Slavic conjunct agreement. Goal Resolution accounts comprise of the assumption made by mainstream research that resolved value (masculine plural) on ConjP goal is readily available to be copied onto probe (Bošković 2009; Franks and Willer-Gold 2014; Marušič et al. 2015; Murphy and Puškar 2018). The Probe Resolution account instead argues that gender resolution takes place on probe once gender values have been copied from the two conjuncts, as proposed by Citko (2018). The current study aims to experimentally test the validity of these two theoretical accounts of gender resolution. In this objective, we first discuss the results of an elicited production study on conjunct agreement in South Slavic (Willer-Gold et al. 2018), which found production times for nine gender combinations to strongly correlate with uniformity of agreement exponents. This finding indicates that simultaneous activation of multiple conjunct agreement strategies is resolved by competition at the level of morphological exponents on probe, offering support for the Probe Resolution account. We then report a novel study comprised of three self-paced reading experiments in Croatian (n: 99) designed to validate the resolved masculine gender on ConjP goal with (in)congruent gender conjuncts. Results of this study suggest <masc> is an early predictor of the gender on the upcoming verbal target but its violation is detected late in the presence of an alternative agreement strategy in the experimental paradigm, and as expected when this alternative is eliminated from the experimental paradigm favouring Goal Resolution theories. Conflicting data from comprehension (self-paced reading) and production (elicited production) studies supporting Goal and Probe approaches are finally considered in the context of the production-comprehension asymmetry often observed in gender attraction studies.

Code-switching costs from Chinese-English relative clauses processing.

The source of costs is a primary concern in code-switching, yet a consensus has not yet been reached. This study investigates whether code-switching during syntactic processing in Chinese-English dual languages results in a cost. We use Chinese and English relative clauses in either object (Experiment 1) or subject (Experiment 2, which has a more complex structure) positions to test the costs in syntactic processing. Forty-seven Chinese-English bilinguals and 17 English-Chinese bilinguals participated in acceptability judgment tests and self-paced reading experiments. The statistical findings indicate that syntactic processing is a source of the costs incurred in code-switching, as evidenced by the code-switching costs observed in the head movement during relative clause comprehension. The outcomes are consistent with the implications of the 4-Morpheme Model and the Matrix Language Framework. Additionally, the experiment shows that the processing of relative clauses depends on the underlying structures, which is consistent with the Dependency Locality Theory.
