Motivational factors and structured input effects on the acquisition of English causative passive forms

This study investigated the possible effects of motivational factors on the positive effects generated by structured input on the acquisition of English causative passive forms. This investigation builds upon the work carried out within the structured input research framework with the intention to measure online effects utilising a self-paced reading test. The self-paced reading test is a reliable measurement of language processing. Fifty Chinese (L1) subjects participated in the current study. They were all learning English in a university in the United Kingdom. After receiving two motivation questionnaires three groups were formed: structured input low-motivated (n = 15); structured input high-motivated (n = 20); and a control group (n = 15). Pre-tests and post-tests (immediate and delayed) were administered before and after the instructional treatment period which lasted for 3 h over a two-day period. The main findings from this experimental study confirmed the positive effects of structured input in facilitating the correct processing of English causative passive forms (accuracy and response time). The structured input activities groups improved equally from pre-to post-tests and they both retained the positive instructional effects over a 3-week period. Motivation was not a factor influencing the positive results generated by structured input. The present study contributes to the current call in the field for more empirical research to investigate the role of instruction and individual differences and the use of online tests to measure in-depth language processing.

Number Attraction in EFL Learners’ Subject-Verb Agreement and the Effect of Distance

The present study aims to investigate Korean EFL learners’ sensitivity to subject-verb agreement violation and to examine effects of local number attraction, plural markedness, and distance on their agreement computation. Sixty-six Korean adult learners of English at mid- and high proficiencies participated in an experiment which combined self-paced reading and timed acceptability judgement. They were asked to read sentences region by region and rate their acceptability. All sentences contained a local noun that disagreed with the subject noun in number. They varied in terms of (i) grammaticality (i.e., agreement-violating vs. non-violating) and (ii) noun number (i.e., singular subject N/plural local N vs. plural subject N/singular local N). Half of the items had a short-distance condition and half had a long-distance condition. Analyses of participants’ responses showed that learners were generally sensitive to agreement violation when judging acceptability. In addition, proficient learners exhibited biased sensitivity to noun plurality, resulting in mismatch asymmetry in both acceptability judgment and self-paced reading, showing native-like response patterns. Distance between the subject and the verb resulted in reduced sensitivity to agreement violation. These findings suggest that learners can gradually become more sensitive to agreement violation and process subject-verb agreement in a nativelike pattern even when relevant morpho-syntactic features are not instantiated in their L1.

어순 교체에 따른 한국어 피동문 실시간 처리 연구 - 일본인 학습자를 대상으로 -

This study investigated whether L1 Japanese learners of Korean can acquire the word order alternations of the Korean passive. In self-paced reading, Korean native speakers (n = 30) showed greater sensitivity to structural cues than semantic ones, while Japanese L2 Korean speakers (n = 60) showed no difference in reading time, regardless of proficiency, as well as showing no sensitivity to structural or semantic cues. These results indicate that Japanese L2 Korean speakers have difficulty with the on-line processing of sentences despite the morphological congruency between L1 and L2.

From implicit to explicit

Abstract The presence of discourse relations can be marked explicitly with lexical items such as specialized and underspecified connectives or left implicit. It is now well established that the presence of specialized connective facilitates the processing of these relations. The question is to gauge how different degrees of explicitness affect the processing of discourse relations. This study investigates this question with respect to two relations, which are fundamental to our cognition and which are closely tied: causal relations and temporal relations. We carried out a self-paced reading experiment, in which we sought to compare the cost of inferring the presence of causal vs. temporal relations in the absence vs. presence of a connective indicating a given relation in French. For the explicit marking, two types of connectives were tested – one specialized for each relation (donc for causality and puis for temporality) and one underspecified (et in its temporal and causal readings). Overall, our results confirm the facilitator role of discourse connectives: we find that explicit discourse relations are processed faster than implicit ones. The specific (rather than underspecified) connective facilitates processing for temporal relations but not for causal relations; and temporal relations were read equally fast as causal relations.

Diving into a pool or volcano? Examining the influence of sentence context and task demands on sentence reading in younger and older adults.

Cognitive ageing is often associated with slower lexical processing, which might influence both language production and comprehension. Words are typically used in context, which can further influence word processing and potential age differences. However, it remains unclear how older adults are affected by context during reading. Older adults are reported to have in-tact semantic knowledge, which could potentially help them to process words predicted by semantic information in the preceding context. However, potential difficulties with semantic control might mean older adults have greater difficulty suppressing interfering information from mismatching contexts. In this study we examined the influence of contexts that either predicted a specific target word ("matched", e.g., "The man watched the lava erupt from the volcano") or predicted another word than the target ("mismatched", e.g., "The swimmer dived into the volcano") as compared to neutral contexts (e.g., "They went to see the volcano"). We also examined the potential role of task demands by asking participants to either just read the sentences for comprehension or to answer questions. Forty younger adults (18-35 years old) and forty older adults (65-80 years old) completed a self-paced reading task in which we measured reading times for the target words. Older adults showed slower reading times overall. Matched sentence contexts facilitated reading times in both age groups. Surprisingly, mismatched sentence contexts did not hinder reading times in either age group. Furthermore, reading times were not influenced by task demands. Together, this shows the importance of studying language in context. While interference from mismatching sentence contexts might have not been substantial enough to delay reading, reading was faster when processing expected words. This suggests older adults can indeed benefit from semantic knowledge to facilitate word processing during comprehension. This occurred even when no additional task was presented and people were purely reading for comprehension.

Locality Bias Effect and Interpretation of Thai Reflexive Anaphors

Abstract The two forms of Thai reflexive anaphors, tuaɁeeŋ ‘self’ and tua+pronoun+Ɂeeŋ ‘pronoun-self’, have been claimed to exhibit different referential patterns. While tuaɁeeŋ only co-refers with a local antecedent np within the same clause, tua+pronoun+Ɂeeŋ can refer to both local and distant antecedent np s. In this study, a self-paced reading experiment was used to examine whether and how Locality Bias guided the comprehenders’ online interpretation of tuaɁeeŋ and tua+pronoun+Ɂeeŋ. Our results showed that the reading time was significantly faster when a reflexive anaphor referred to a local np than when it did to a a distant np, regardless of the forms. This suggests that a local antecedent was preferred for both types of reflexives manifesting locality bias effect. Post hoc tests revealed that tua+pronoun+Ɂeeŋ appeared to be more sensitive to the locality bias than tuaɁeeŋ. This may result from the presence of the personal feature in tua+pronoun+Ɂeeŋ, which could restrict reference to local antecedents.

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.

Does a walk-through video help the parser down the garden-path? A visually enhanced self-paced reading study in Dutch.

The human language processing mechanism assigns a structure to the incoming materials as they unfold. There is evidence that the parser prefers some attachment types over others; however, theories of sentence processing are still in dispute over the stage at which each source of information contributes to the parsing system. The present study aims to identify the nature of initial parsing decisions during sentence processing through manipulating attachment type and verbs' argument structure. To this end, we designed a self-paced reading task using globally ambiguous constructions in Dutch. The structures included double locative prepositional phrases (PPs) where the first PP could attach both to the verb (high attachment) and the noun preceding it (low attachment). To disambiguate the structures, we presented a visual context in the form of short animation clips prior to each reading task. Furthermore, we manipulated the argument structure of the sentences using 2- and 3-argument verbs. The results showed that parsing decisions were influenced by contextual cues depending on the argument structure of the verb. That is, the visual context overcame the preference for high attachment only in the case of 2-argument verbs, while this preference persisted in structures including 3-argument verbs as represented by longer reading times for the low attachment interpretations. These findings can be taken as evidence that our language processing system actively integrates information from linguistic and non-linguistic sources from the initial stages of analysis to build up meaning. We discuss our findings in light of serial and parallel models of sentence processing.

Prediction at the intersection of sentence context and word form: Evidence from eye-movements and self-paced reading

A key issue in language processing is how we recognize and understand words in sentences. Research on sentence reading indicates that the time we need to read a word depends on how (un)expected it is. Research on single word recognition shows that each word also has its own recognition dynamics based on the relation between its orthographic form and its meaning. It is not clear, however, how these sentence-level and word-level dynamics interact. In the present study, we examine the joint impact of these sources of information during sentence reading. We analyze existing eye-tracking and self-paced reading data (Frank et al., 2013, Behavior Research Methods, 45[4], 1182–1190) to investigate the interplay of sentence-level prediction (operationalized as Surprisal) and word Orthography-Semantics Consistency in activating word meaning in sentence processing. Results indicate that both Surprisal and Orthography-Semantics Consistency exert an influence on several reading measures. The shape of the observed interaction differs, but the results give compelling indication for a general trade-off between expectations based on sentence context and cues to meaning from word orthography.

Individual differences modulate sensitivity to implicit causality bias in both native and nonnative processing

AbstractThe question of whether L2 learners can use discourse cues online during pronoun resolution remains debated in the field. We examine one factor that has been argued to impact pronoun resolution in native speakers, implicit causality (IC) bias, a property related to certain verbs in which one of verb’s arguments are considered to be the cause of an action. We investigate whether individual differences modulate sensitivity to IC bias in both native English speakers and Chinese-speaking learners of English, examining whether variability is similarly explained in the two populations. Results from a sentence completion task and a self-paced reading (SPR) task show similar sensitivity to IC bias in both groups; reading times on the SPR task were also modulated by working memory and vocabulary knowledge. The findings suggest that L2 learners are successful in using discourse-level cues during processing and that variability is qualitatively similar in both learners and natives.

Scalar implicatures in adult L2 learners: A self-paced reading study

Using self-paced reading, the present study compared native English and adult L1-Korean–L2-English speakers’ processing behaviors during online comprehension of underinformative scalar sentences and non-scalar sentences like Some/All elephants have trunks and ears. Results indicate that native speakers showed online sensitivity (i.e. slower reading) to underinformative scalar sentences relative to non-scalar sentences, but second language (L2) speakers did not. These results are interpreted in support of the Relevance Theory claim that scalar implicature generation is modulated by contextual and individual factors, in particular by the language condition, that is, whether sentences are presented in L1-English versus L2-English.

Conscious rereading is confirmatory: Evidence from bidirectional self-paced reading

Rereading during sentence processing can be confirmatory, in which case it serves to increase readers' certainty in their current interpretation, or it can be revisionary, in which case it serves to correct a misinterpretation (Christianson, Luke, Hussey, & Wochna, 2017). The distinction is particularly relevant in garden-path sentences, which have been argued to trigger revisionary rereading (Frazier & Rayner, 1982). In two web-based experiments that compare garden-path sentences with other linguistic constructions, we investigate deliberate rereading in the recently-proposed bidirectional self-paced reading (BSPR) paradigm (Paape & Vasishth, 2022). Our results show evidence for selective rereading only in very difficult garden-path sentences. Additionally, our results suggest that conscious, selective rereading is confirmatory: Readers find garden-path sentences less rather than more acceptable after selective rereading, suggesting that they reread either to confirm their initial analysis or to confirm the perceived ungrammaticality of the sentence. We discuss the role of conscious awareness in dealing with different types of linguistic inconsistency.

Processing pro-drop features in heritage Turkish.

Previous studies have reported that null subject is not completely lost in heritage speakers, but there is an increase in the production and acceptance of overt subjects. Turkish is a pro-drop language and as a typical feature of pro-drop languages, it requires obligatory verb agreement marking for sentences with null subjects. However, Turkish subject-verb agreement marking is an example of optional agreement in which the 3rd person plural subject has optionality and can be used with singular verb forms under certain conditions. The current study investigates the reading times (RTs) of plural-marked and unmarked verbs in sentences with overt and null subjects during real time sentence processing in comparison to non-heritage speakers of Turkish via a self-paced reading experiment. Significant differences were observed between the heritage and non-heritage speakers of Turkish indicating both quantitative and qualitative real-time processing differences between the two groups. These differences suggest that Turkish heritage speakers need more time to integrate the information in real time processing.

The sandwich effect in L3 acquisition: A look at the Catalan and Spanish grammars of highly advanced speakers of L3 English

Aims and objectives: This study examines the extent to which the acquisition of a highly advanced third language (L3) will affect previously (early) acquired languages. We directly test the main tenets of the differential stability hypothesis. Design/method/approach: We test 72 Catalan–Spanish bilinguals divided across four groups using two dimensions: (a) order of acquisition and (b) proficiency/exposure in L3 English. We administered two self-paced reading tasks (one in Catalan and the other in Spanish) to explore their processing of negative concord items. Data analysis: Using generalized linear mixed-effects models, we analysed the effect English had on the processing of negative concord items in Catalan and Spanish in three different conditions of interest. Findings/conclusions: The results partially confirm the tenets of the differential stability hypothesis (DSH). We show that first language (L1) and second language (L2) are differentially affected by the acquisition of an L3. We further show that there are different degrees of vulnerability for different syntactic contexts in an L2. We propose a novel effect in the study of L3 regressive effects that can complement the tenets of the DSH: the sandwich effect in L3 acquisition. Originality: The study provides the first empirical investigation of the tenets of the DSH. Significance/implications: This study offers a new effect in L3 acquisition and we put forward how we can test it and propose new directions to explore regressive transfer effects.

Variation in the processing of grammatical norm violations

Abstract So far, processing studies on grammatical norm violations (GNVs) in Dutch (i.e. als ‘as’ in comparatives) have mainly focused on general differences between GNVs and their grammatical and ungrammatical counterparts. The present study is the first to also systematically investigate between-participant and between-construction variation in the processing of GNVs, using a self-paced reading task. Age and educational level were investigated as potential sources of between-participant variation, and between-construction variation was assessed by including three GNVs that vary in the amount of prescriptive attention they receive in society. Results indeed showed that the processing of GNVs was influenced by the age and educational level of participants. Moreover, different results were obtained for different norm violations. Based on these results, we conclude that it is very important to take into account differences between participants and constructions when studying the processing of GNVs.

Interactions between lexical and syntactic L1-L2 overlap: Effects of gender congruency on L2 sentence processing in L1 Spanish-L2 German speakers

AbstractBringing together lines of research from sentence processing and lexical access, this empirical study investigates the interplay between lexical (grammatical gender) and syntactic (word order) cross-linguistic overlap in L2 German. Eighty-six L1 Spanish-L2 German and thirty-six monolingual German adults completed a German self-paced reading task with noun phrases (NPs) manipulated by L1-L2 gender congruency (congruent, incongruent, neuter) and L1-L2 adjective-noun word order (pre- vs. postnominal adjectives). The study examines the effects of gender congruency, the type of L1-L2 gender mapping (i.e., presence vs. absence of each class in L1 and L2), and L2 proficiency level. Results show that the detection of ungrammatical word order in L2 German interacts with gender congruency, in that L2 speakers are only sensitive to word order violations for sentences with gender-congruent nouns. The detection of ungrammaticality for sentences containing gender-incongruent nouns only emerges at higher L2 proficiency levels. These findings underscore the role of cross-linguistic lexical overlap in syntactic processing.

WORD ORDER PROCESSING IN GERMAN AS A FOREIGN LANGUAGE

In an experiment on processing effort in sentence comprehension, preference hypotheses on word order and relative clause position were tested in German as a second or foreign language. The experiment involved 62 Slovenian students of German studies in Maribor as participants. The linguistic material consisted of 16 utterances, each with a main clause and a relative clause and each of them a subject-initial or object-initial. The relative clause could occur either after the first or second noun phrase. The procedure used was the self-paced reading paradigm. After each test unit, the participants were asked a comprehension question, either about the subject of the main clause or about the subject of the relative clause. The experiment confirmed the hypotheses that response accuracy to a comprehension question was higher when a clause was subject-initial and when the relative clause occurred after the first noun phrase of the main clause. The experiment did not confirm the assumed interaction between word order and position of the relative clause.

Effects of working memory capacity and distance-based complexity on agreement processing: a crosslinguistic competition account

Abstract This study examined the extent to which working memory (WM) capacity and distance-based complexity influenced how second language (L2) learners used morphosyntactic information incrementally during online processing of L2 English long-distance subject-verb number agreement dependencies. The moving-window self-paced reading experiment involved 40 agreement-lacking first language (L1) Thai learners of English and 40 native English speakers. Distance-based complexity was manipulated based on whether the agreement controller and the agreeing verb were intervened by a short-distance subject-extracted relative clause or a long-distance object-extracted relative clause in line with the Dependency Locality Theory. The findings indicated that both native speakers and L2 learners experienced less processing difficulty in short-distance conditions, showing heightened sensitivity to agreement violations. Their sensitivity was, however, modulated as a function of distance-based complexity and WM capacity. The L2 learners’ lack of sensitivity in the long-distance conditions was associated with their limited pool of cognitive resources. Consistent with the L1–L2 structural competition account, these findings suggest in relation to morphology learning in SLA that L2 learners may labor under parallel activation during crosslinguistic competition, whereby cognitive resources are insufficient to resolve long-distance agreement dependencies, thus resulting in reduced sensitivity to L2 morphosyntactic violations.

핵심명사의 통사적 위치가 한국인 학습자의 중국어 주격/목적격 관계절 처리에 미치는 영향

This study examines the acquisition situation of Chinese relative clause phrases by Korean learners through a self-paced reading task. This study aims to analyze three parts. First, The cognitive processing characteristics of Korean learners of different Chinese level groups when they process and comprehend Chinese subjective and objective relative clauses. Second, the effect of the syntactic position of head nouns on the cognitive processing of Chinese subjective and objective relative clauses. Third, the universal applicability of the representative second language relative clause acquisition theory hypothesis. In this study, two-way ANOVA was performed by dividing the within-subject of the experiment into different relative clause syntax types and between-subjects into a high-level group and a low-level group. The results showed that there were some differences between the high-level group and the lower-level group in the processing of Chinese subjective-objective relative clause sentences. These differences appeared in the reaction times of the experiments. The reaction time for each experimental sentence in the low-level group was much longer than that in the high-level group. In addition, the low-level group exhibited cognitive information processing characteristics that were affected by canonical word order, which is “NVN”, and exhibited the “garden path effect” when processing relative clauses. However, the high-level group showed a pattern of processing sentences relying on the “filler-gap dependencies”clue. Therefore it was found that as the learner’s second language level improved, the dependence on syntactic information increased when gradually acquiring procedural knowledge and understanding sentences. In addition, through the analysis of related data, it was found that the low-level group was less affected by the syntactic positional factors of the head noun, and there was no preference between the Chinese subjective relative clause and the objective relative clause. However, the high-level group showed the processing advantage of SRC (subjective relative clause) located in the subject position of the main clause. The results support the “frequency hypothesis”, “word order typicality hypothesis”, “structural distance hypothesis”, and the “integrated competition model,” consistent with the existing second language acquistion theories.
