Control and intermediate scrambling: An investigation of Kazakh relative clauses

This paper investigates apparent locality violations in Kazakh (Turkic) relative clauses. The empirical starting point of this study is the configuration where the genitive-marked relative clause subject establishes agreement with the noun phrase modified by the relative clause, constituting an ostensibly non-local Agree relation, a phenomenon that is common among Turkic, Mongolic, Tungusic and Finno-Ugric languages. Contra previous proposals arguing that the subject is situated inside a defective relative clause and it gets case from the D head of the modified noun phrase, this paper proposes a novel analysis of this phenomenon: the genitive phrase is base-generated in the possessor position and it controls a PRO subject in the relative clause. After establishing that the genitive “subjects” are relative clause-external, the paper turns to extraction out of the relative clause: RC constituents can undergo intermediate scrambling to the left of the genitive-marked phrase. This is unexpected under the assumption that relative clauses are strong islands for extraction. The paper suggests that this type of RC allows extraction because it is not an adjunct.

Continuous Theta-Burst Stimulation on the Left Posterior Inferior Frontal Gyrus Perturbs Complex Syntactic Processing Stability in Mandarin Chinese

Abstract The structure of human language is inherently hierarchical. The left posterior inferior frontal gyrus (LpIFG) is proposed to be a core region for constructing syntactic hierarchies. However, it remains unclear whether LpIFG plays a causal role in syntactic processing in Mandarin Chinese and whether its contribution depends on syntactic complexity, working memory, or both. We addressed these questions by applying inhibitory continuous theta-burst stimulation (cTBS) over LpIFG. Thirty-two participants processed sentences containing embedded relative clauses (i.e., complex syntactic processing), syntactically simpler coordinated sentences (i.e., simple syntactic processing), and non-hierarchical word lists (i.e., word list processing) after receiving real or sham cTBS. We found that cTBS significantly increased the coefficient of variation, a representative index of processing stability, in complex syntactic processing (esp., when subject relative clause was embedded) but not in the other two conditions. No significant changes in d′ and reaction time were detected in these conditions. The findings suggest that (a) inhibitory effect of cTBS on the LpIFG might be prominent in perturbing the complex syntactic processing stability but subtle in altering the processing quality; and (b) the causal role of the LpIFG seems to be specific for syntactic processing rather than working memory capacity, further evidencing their separability in LpIFG. Collectively, these results support the notion of the LpIFG as a core region for complex syntactic processing across languages.

An Investigation of Syntactic Impairment in Relative Clauses of a Non-Fluent Aphasic Patient

This paper reports on a study on the typical characterization of syntactic impairment in relative clauses found in a patient diagnosed with non-fluent aphasia or also known as Broca ‘s aphasia at National Stroke Association of Malaysia (NASAM), Petaling Jaya, Malaysia. The study adopts the theory of Chomsky’s (1981) Government and Binding Theory that consist of (D)eep Structure and (S)urface Structure as a framework for the description of syntactic impairment and adopts an influential hypothesis by Grodzinsky’s (1990) Trace Deletion Hypothesis (TDH) concerning agrammatism. The sentence structure used in this study is syntactically identical to the base order subject-verb-object (SVO) except for the movement of the object to the beginning of the sentence known as derived order that will result to the formation of object-subject-verb (OSV) in English, and thus enable examination of syntactic movement in agrammatic comprehension. This study involves one patient with non-fluent aphasia, native speaker of Tamil and speaker of English as second language from NASAM, performing a sentence - to-picture matching test. This study reveals the patient’s comprehension of subject relative clauses (SVO structure) are significantly above chance level, but object relative clauses (OSV structure) are at chance level. This study reveals that the score obtained by the patient is within the percentage and performance level (standard norm) proposed by Grodzinsky. These results also show that the non-fluent aphasic patient’s ability to comprehend the relative clauses that involve movement of a noun phrase is impaired.

Bilingual children’s online processing of relative clauses

Abstract Long-distance dependencies such as relative clauses (RCs) are known to be vulnerable in heritage grammars (e.g., Montrul, 2008). Previous studies in RC comprehension have shown that heritage language (HL) children show similar comprehension to monolingual children (Jia & Paradis, 2020), while differential performance has also been found (Kidd et al., 2015). The present study investigates 11–13-year-old monolingual and German-dominant HL children’s real-time parsing strategies in subject relative clause (SRC) and object relative clause (ORC) processing in Greek. We conducted a self-paced listening task in Greek in which we manipulated the type of RC (subject vs. object), and the RC internal word order (canonical vs. scrambled). Our analyses revealed no significant group differences between HL and monolingual children. Both groups of children processed SRCs faster than ORCs on the critical RC verb segment. We also examined if case-marked pre-verbal NPs would facilitate the processing of ORC structures. Although children processed pre-verbal faster than post-verbal NPs, ORC structures with pre-verbal NPs received the lowest scores in the grammaticality judgment task. We discuss these findings on the grounds of Relativized Minimality (Friedmann et al., 2009) and Fodor and Inoue’s (2000) Diagnosis and Repair Model.

Subject‐Object Asymmetries and the Development of Relative Clauses between Late Middle English and Early Modern English

AbstractThis paper presents the results of a corpus study on the Wycliffe Bible and the King James Bible, examining the distribution of the pronouns who(m)/which and the complementiser that in relative clauses with a personal referent. The data indicate that the decisive factor in both periods was the function of the gap (subject vs. non‐subject): wh‐pronouns are preferred in object relative clauses, while that is preferred in subject relative clauses. In addition, the paper argues that the subject/non‐subject distinction was decisive not only regarding the major wh/that distribution but also regarding the who(m)/which distinction. While in the case of the wh/that distinction, a syntactic difference (relative pronoun versus relative complementiser) underlies the attested asymmetry, the pronouns who(m) and which do not differ in their core syntactic properties. The data clearly indicate that both the wh‐strategy in general and the pronoun who(m) in particular started to spread from the lower functions of the Noun Phrase Accessibility Hierarchy, whereby the spread of who(m) was one step behind the general spread of the wh‐strategy. The findings thus suggest that asymmetries along the lines of the Noun Phrase Accessibility Hierarchy are not necessarily paired up with syntactic asymmetries.

Capturing individual differences in sentence processing: How reliable is the self-paced reading task?

Advances in research on language processing have originally come from group-level comparisons, but there is now a growing interest in individual differences. To investigate individual differences, tasks that have shown robust group-level differences are often used with the implicit assumption that they will also be reliable when used as an individual differences measure. Here, we examined whether one of the primary tasks used in psycholinguistic research on language processing, the self-paced reading task, can reliably measure individual differences in relative clause processing. We replicated the well-established effects of relative clauses at the group level, with object relative clauses being more difficult to process than subject relative clauses. However, when using difference scores, the reliability of the size of the relative clause effect was close to zero because the self-paced reading times for the different relative clause types were highly correlated within individuals. Nonetheless, we found that the self-paced reading task can be used to reliably capture individual differences in overall reading speed as well as key sentence regions when the two types of relative clause sentences are considered separately. Our results indicate that both the reliability and validity of different sentence regions need to be assessed to determine whether and when self-paced reading can be used to examine individual differences in language processing.

How semantics works in Chinese relative clause processing: insights from eye tracking.

Recent years have witnessed much research on semantic analysis and syntactic anatomy in ordinary language processing. However, it is still a matter of considerable debate about when and how the semantic integration of single word meanings works and interacts with syntax during on-line comprehension. This study, in an eye-tracking paradigm, took 38 native speakers of Mandarin Chinese as the participants and took Chinese relative clauses as stimuli to figure out the functions of semantics by investigating the conditioning semantic factors influencing and governing the word order variation of Chinese relative clauses during different processing stages. Accordingly, this study manipulated two syntactic variables, i.e., relative clause type and the position of the numeral-classifier sequence (NCL) in the relative clause, as well as a semantic variable, i.e., the abstractness of the head noun that the relative clause modified. Specifically, the study addressed two questions: (1) when semantics is activated and interacts with syntax and (2) how semantics affects syntax during the time course of Chinese relative clause processing. The results indicated that: (1) Semantics was activated and interacted with syntax during the early and late processing stages of Chinese relative clauses, which challenged the sequential order of syntactic and semantic processes, and supported the claims of the Concurrent Processing Model. (2) The syntactic order of the Chinese relative clause was affected by the semantic information of the head noun that the clause modified. Object-extraction relative clauses (ORCs) had a conjunction preference for the order "an object relative clause preceding the numeral-classifier sequence and the head noun." Instead, the subject-extraction relative clause (SRC) which modified a concrete noun (CN) had a co-occurrence preference for the order "numeral-classifier sequence preceding the subject relative clause and the head noun," while the subject-extraction relative clause which modified an abstract noun (AN) had a co-occurrence preference for the order "subject relative clause preceding the numeral-classifier sequence and the head noun." The findings of this study were evaluated in light of the perspectives of truth value semantics of the syntactic components, the semantic compatibility of numeral-classifier sequence and its modified noun as well as the discourse functions of outer modifier nominals and inner modifier nominals.

Six-year-olds’ comprehension of object-gapped relative clause sentences: Investigating the contribution of NP number mismatch

Comprehension of sentences with a center-embedded, object-gapped relative clause (ORC) is challenging for children as well as adults. Mismatching lexical and grammatical features of subject noun phrases (NPs) across the main clause and relative clause has been shown to facilitate comprehension. Adani et al. concluded that children’s comprehension improved under conditions of NP number mismatch (e.g., singular main clause subject and plural relative clause subject) as compared with NP number match (e.g., both singular subjects). However, their stimuli provided number information on verb phrases (VPs) as well as NPs creating a confound for conclusions about facilitative effects of NP number mismatch. In this study, we isolated the contribution of NP number mismatch. Notably, 32 6-year-olds with typical language participated in a center-embedded, ORC sentence comprehension task with 4 types of stimuli: (a) NP number mismatch without VP number information (NP mismatch only), (b) NP number match without VP number information (NP match only), (c) NP number mismatch with VP number mismatch (NP + VP mismatch), and (d) NP number match with VP number match (NP + VP match). Children selected one of four pictures in an array to a verbally presented relative clause sentence; 56 sentences were presented. The within-subjects comparison for NP mismatch only and NP match only was not significant. However, the within-subjects comparison for NP mismatch only and NP + VP mismatch was significant. Children were more successful in NP + VP mismatch sentence comprehension ([Formula: see text] = 0.70).

Relative Marker Omission in Thai: Evidence from Native Speakers’ Acceptability Judgments and Language Transfer

Relative clauses are a well-studied phenomenon in linguistics, giving rise to discoveries about human language. In this study, we consider thîi-less relative clauses in Thai, in which a relative marker may be omitted under certain circumstances. The objectives of the study are to identify native speakers’ conditions of thîi omission and to explore whether knowledge of the conditions is transferred to their relative marker omission in English. Two parallel acceptability judgment tasks in Thai and English were conducted: 437 students from various faculties at Kasetsart University judged the acceptability of thîi-less relative clauses while 233 non-English major students and 83 English major students at the same university judged the acceptability of English marker-less relative clauses. Results showed the most favorable condition for thîi omission is a subject relative clause that modifies a general head noun and contains a non-eventive predicate. Such a structure of a thîi-less relative clause resembles the basic construc­tion of nominal modification, i.e., a noun modified by a phrase. Results also showed the transfer of the thîi omission pattern into English, particularly among students with lower English proficiency. With L1 and L2 supporting data, the study demonstrated that syntax and semantics are determinants of relative marker omission in Thai.

The Acquisition of Relative Clauses in Autism: The Role of Executive Functions and Language

PurposeRelative clauses present a well-known processing asymmetry between object-extracted and subject-extracted dependencies across both typical and atypical populations. The present study aimed at exploring the comprehension of object and subject relative clauses as conceptualized by the Relativized Minimality framework in autistic children and in a group of age- and IQ-matched typically-developing children. The study also explored the way performance in relative clauses would be affected by the children’s language and executive function skills.MethodRelative clause comprehension was tested through a sentence-picture matching task and language was tested with a receptive vocabulary task. Executive functions were assessed through backward digit recall and a Flanker test.ResultsObject relative clauses were harder to parse for both groups than subject relatives, while number mismatch between the moved object Noun Phrase and the intervening subject Noun Phrase in object relatives boosted both groups’ performances. Typically-developing children’s performance in object relatives was predicted by both language and executive functions, while autistic children failed to use language and did not systematically draw on their executive functions in object relative clause comprehension.ConclusionThe findings suggest that relative clause processing in autism follows a normal developmental trajectory, and that difficulty with parsing object relative clauses stems from reduced language and executive functions rather than deficits in the children’s morphosyntactic skills.

Analysis of the Problems in the Use of English Restrictive Relative Clauses by Second Language Learners of Hazara Division

This research study investigates the difficulties faced by second language learners of Hazara division while comprehending English restrictive relative clauses and compares the comprehension sequences with the predictions of Subject-object hierarchy hypothesis and Noun phrase accessibility hierarchy. The study also examines the most challenging relative pronouns for second language learners of Hazara division. Data from one hundred and fifty undergraduate level students across various universities of Hazara division was analyzed. This study concludes that subject relative clauses are the easiest to comprehend, while genitive relative clauses are the most difficult, making the resultant hierarchy align with noun phrase accessibility hierarchy. On the other hand, deviation from Subject- object hierarchy can be observed, as subject-subject relative clauses are the easiest and subject-object relative clauses are the most difficult to comprehend. Additionally, the study identifies relative pronoun "whom" as the most challenging, and "when" as the easiest to comprehend.

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.

Exploring the effects of animacy and verb type on the processing asymmetry between SRC and ORC among Chinese EFL learners

This study investigates the production and comprehension of subject relative clause (SRC) and object relative clause (ORC) in English by Chinese EFL learners. Two experiments are reported. Using a sentence completion task to elicit the production of relative clauses (RCs), Experiment 1 examined the distributional patterns of SRC and ORC and showed that SRC was more frequently distributed than ORC. In addition, animacy and verb type had effects on the asymmetric distribution of SRC and ORC. Using a word-by-word moving-window self-paced reading paradigm, Experiment 2 further compared reading times (RTs) of SRC and ORC containing different animacy and verb type configurations. Reading difficulties in ORC were observed, and comprehension difficulties of certain configurations of animacy and verb type just mirrored their frequencies in the first experiment. Taken together, the processing asymmetry of SRC and ORC has been observed in both comprehension and production processes. Comprehension difficulties are believed to stem from the asymmetric distributions of sentence patterns involving different animacy and verb type configurations. These findings suggest that comprehension difficulties are correlated with the distributional patterns, which could provide strong support to the Production-Distribution-Comprehension account, the experience-based approach applicable in language acquisition.

Priming Center-Embedded Object and Extraposed Subject Relative Clauses in Persian Language Production: Searching for Persistence of Hierarchical Configuration.

Substantial evidence suggests that priming can co-occur at different syntactic and nonsyntactic levels. In this study, we further explore two loci of priming concerned with hierarchical configuration and thematic information using relative clause (RC) constructions. In a comprehension-to-production task, Persian speakers (42 adults and 42 children) described pictures after hearing extraposed subject or center-embedded object RCs containing the same or different verbs. We ask whether priming the object RC mitigates the computational cost of center-embedding and thus increases the subsequent production of this infrequent structure. We also measured persistence effects associated with the assignment of emphasis to thematic roles, examining whether a particular portrayal of an event is captured and reproduced (e.g., foregrounding the patient). Although this study could not establish any significant priming effects in the production of the center-embedded object RC, we observed that adults used this construction more in the same verbs condition. The overall results instead revealed strong evidence for thematic emphasis persistence, such that patient-emphasis object relatives further elicited functionally equivalent RC constructions. We discuss priming of hierarchical configuration as a candidate locus and explain the activation of functional information from the speaker's perspective.

Functional near-infrared spectroscopy shows that object relative clauses are more difficult to process than subject relative clauses in Turkish.

It was suggested that processing subject relative clauses (SRCs) is universally easier than processing object relative clauses (ORCs) based on the studies carried out in head-initial languages such as English and German. However, studies in head-final languages such as Chinese and Basque contradicted this claim. Turkish is also a head-final language. Existing relative clause processing literature in Turkish is based solely on behavioural metrics. Even though an ORC processing disadvantage was suggested for Turkish, the results were not conclusive. Therefore, we aimed to investigate the neural dynamics of relative clause processing in Turkish. We asked 14 native Turkish speakers to answer yes/no questions about 24 sentences each containing either a SRCor ORC while their prefrontal hemodynamic activity was recorded with functional near-infrared spectroscopy. Our findings revealed hemodynamic activity in the lateral portions of the left prefrontal cortex for both conditions. However, hemodynamic activity was more widespread in prefrontal regions in ORCcompared to SRC condition. Even though the behavioural metrics failed to produce a significant difference between the conditions, direct ORC > SRC contrast revealed significant activity in the left inferior frontal cortex, a region heavily involved in language processing, as well as in left and right dorsolateral prefrontal cortices, which are also known to be involved in language processing-related and conflict monitoring-related processes, respectively. Our findings indicate that processing ORCs is more difficult and requires further prefrontal resources than processing SRCs in Turkish, thus refuting the head-directionality-based explanations of relative clause processing asymmetries.

Features matter: the role of number and gender features during the online processing of subject- and object- relative clauses in Italian

ABSTRACT In this study, we investigated whether different morphosyntactic features, i.e. number and gender, play a role during the adult online comprehension of subject relative clauses (SRC) and object relative clauses (ORC), in Italian. This study was inspired by developmental studies showing that children struggle with ORC compared to SRC; yet, ORC comprehension improves if the head and the subject of the RC mismatch in relevant morphosyntactic features (e.g. number but not gender in Italian, based on the featural Relativized Minimality principle, fRM). We found that Italian adults read ORC more slowly than SRC verbs; moreover, ORC verbs were read faster in the head-subject number mismatch condition, while there was no facilitation in the head-subject gender mismatch condition, in line with developmental studies and fRM. We conclude that online parsing is feature-sensitive, that features are not all equally “relevant”, and that current models should be refined to account for these differences.

A subject relative clause preference in a split-ergative language: ERP evidence from Georgian

A fascinating descriptive property of human language processing whose explanation is still debated is that subject-gap relative clauses are easier to process than object-gap relative clauses, across a broad range of languages with different properties. However, recent work suggests that this generalization does not hold in Basque, an ergative language, and has motivated an alternative generalization in which the preference is for gaps in morphologically unmarked positions—subjects in nominative-accusative languages, and objects and intransitive subjects in ergative-absolutive languages. Here we examined whether this generalization extends to another ergative-absolutive language, Georgian. ERP and self-paced reading results show a large anterior negativity and slower reading times when a relative clause is disambiguated to an object relative vs a subject relative. These data thus suggest that in at least some ergative-absolutive languages, the classic descriptive generalization—that object relative clauses are more costly than subject relative clauses—still holds.

Focus on form in task-based language teaching: The case of Turkish

This study aims to reveal how task-based and form-focused language teaching materials affect success in teaching Turkish as a foreign language. The study was performed on the assumption that form-focused and task-based language teaching materials, particularly for teaching agglutinative languages, can be designed and can increase student’s success; it investigated to what extent form-focused and task-based materials contribute to the improvement of the use of the target structure. Accordingly, a pretest–posttest design experiment was performed with 54 participants whose mother tongues are different, 27 of whom were placed in the experimental group and 27 in the control group. The material on teaching the (-(y)An) subject relative clause, developed in line with expert opinions encompassing form-focused input enrichment and consciousness-raising tasks, was used with the experimental group, and its contribution to learner success was measured statistically. In the control group, explication regarding the form was done in the form of presentations and no consciousness-raising activities were carried out; the group adhered to the activities in the coursebook. The pretest and posttest results of the participants in the experimental and control groups were evaluated using the SPSS 24 independent samples t-test. It was observed that after the posttest, the experimental group was more successful than the control group was. The findings show that form-focused and task-based practices are more effective in teaching Turkish, an agglutinative language.

Embedded NP error in German object relative clause comprehension: A case for a universal developmental pathway.

We report the results of an eye-tracking study investigating German children's comprehension of subject relative clauses (SRC) and object relative clauses (ORC) with morphologically unambiguous head and embedded noun phrases (NPs). The experimental paradigm was adopted from Adani and Fritzsche. Children's eye movements were tracked on the visual display while they were listening to an SRC or an ORC. Subsequently, they had to choose the most appropriate visual character on the screen to go with a particular relative clause type in a character selection paradigm. All the head NP and the embedded NPs were of masculine gender. Thus, the relative clause syntax was disambiguated by the ending on the relative pronoun and, subsequently, on the determiner in the embedded NP. We computed fixation probabilities towards the syntactic competitor and the embedded NP character in addition to the proportions of looks towards the target character on the screen. Thematic reversal error remained the dominant error type on children's response accuracy data. The subject advantage was also confirmed on the eye-tracking data, though it was overridden in the post-relative clause time window. However, there was a significant increase in fixation probabilities towards the embedded NP character in the ORC, but not in the SRC condition. While children were less efficient to use the morphological information on the relative pronoun to generate an expectation of a non-canonical ORC structure, they obviously used embedded NP morphology later in the sentence to update their ongoing structural analysis.

The Influence of Case and Word Order in Child and Adult Processing of Relative Clauses in Greek

Previous cross-linguistic studies have shown that object relative clauses (ORCs) are typically harder to parse than subject relative clauses (SRCs). The cause of difficulty, however, is still under debate, both in the adult and in the developmental literature. The present study investigates the on-line processing of SRCs and ORCs in Greek-speaking 11- to 12-year-old children and adults, and provides evidence on relative clause processing in Greek—a free word order language. We conducted a self-paced listening task in which we manipulated the type of relative clause (SRC vs. ORC), the RC internal word order (canonical vs. scrambled), and the type of relativizer (relative pronoun vs. complementizer). The results showed that SRCs were overall processed faster than ORCs, providing evidence that children follow similar processing strategies to adults. In addition, accusative case marking facilitated the processing of non-canonical structures in adults but less so in children. Children showed heavy reliance on word order, as they processed nominative and accusative pre-verbal NPs in exactly the same way, while they were strongly garden-pathed in ORCs with post-verbal nominative NPs. We argue that these results are compatible with the Competition Model.
