PRODUCTION AND COMPREHENSION IN PROCESSABILITY THEORY

AbstractThe purpose of this study was to determine whether processability theory (PT; Pienemann, 1998, 2005) accounts for the emergence of grammatical forms and structures in comprehension. Sixty-one learners of English participated in oral interviews that elicited a variety of structures relevant to PT. Learners were divided into two groups: those who produced these structures productively in speech (high level) and those who did not (low level). These groups then read grammatical and ungrammatical sentences with PT structures in a self-paced reading task. Based on Pienemann (1998), PT predicts that the high-level group should perform similarly to native speakers. However, only the native speaker control group demonstrated sensitivity to ungrammaticalities. There was evidence that learners might have acquired lower-stage structures in an implicational order in comprehension, but it was quite mixed. These results have implications for PT and for models of the L2 linguistic system that include both production and comprehension.

The Interaction of Contextual and Syntactic Information in the Processing of Turkish Anaphors.

In contrast with languages where anaphors can be classified into pronouns and reflexives, Turkish has a tripartite system that consists of the anaphors o, kendi, and kendisi. The syntactic literature on these anaphors has proposed that whereas o behaves like a pronoun and kendi behaves like a reflexive, kendisi has a more flexible behavior and it can function as both a pronoun and a reflexive. Using acceptability judgments and a self-paced reading task, we examined how Turkish anaphors are processed in isolated sentences and within larger discourse contexts. We manipulated contextual information by creating passages where the context favored a local, long-distance or extra-sentential referent prior to the appearance of the anaphor. We measured the effect of the context on participants' reading times and their end-of-trial coreference assignments. Our results suggest that contextual information affects the interpretive possibilities associated with an anaphor, but that the influence of context depends on the degree to which the anaphor is syntactically constrained.

Investigating bilinguals’ sensitivity to English regular past morphology: A self-paced reading experiment with Brazilian learners

ABSTRACT It is known that adult learners of English as an additional language (EAL) have difficulty in producing inflectional morphemes such as the third person present singular -s and regular past -ed. One possible explanation is that bilinguals are not sensitive to inflectional morphemes, in comprehension tasks as evidenced by longer latencies at critical positions in reaction time experiments, when compared to native controls. Having the above in mind, the objective of this paper is to investigate if in fact Brazilian EAL bilinguals are sensitive to regular past morphology in a self-paced reading task. Sentences varied on the use or absence of inflectional morphemes. The statistical analysis showed that EAL speakers are not sensitive to past morphology. The results are discussed in light of Distributed Morphology and of previous studies on production and processing of inflectional morphemes in EAL.

Validity of new measures of implicit knowledge: Distinguishing implicit knowledge from automatized explicit knowledge

ABSTRACTAccumulating evidence suggests that time-pressured form-focused tasks like grammaticality judgment tests (GJTs) can measure second language (L2) implicit knowledge. The current paper, however, proposes that these tasks draw on automatized explicit knowledge. A battery of six grammar tests was designed to distinguish automatized explicit knowledge and implicit knowledge. While three time-pressured form-focused tasks (an auditory GJT, a visual GJT, and a fill in the blank test) were hypothesized to measure automatized explicit knowledge, three real-time comprehension tasks (a visual-world task, a word-monitoring task, and a self-paced reading task) were hypothesized to measure implicit knowledge. One hundred advanced L2 Japanese learners with first language Chinese residing in Japan took all six tests. Confirmatory factor analysis and multitrait-multimethod analysis provided an array of evidence supporting that these tests assessed two types of linguistic knowledge separately with little influence from the method effects. The results analyzed separately by length of residence in Japan (a proxy for the amount of naturalistic L2 exposure) showed that learners with longer residence in Japan can draw on implicit knowledge in the real-time comprehension tasks with more stability than those with shorter residence. These findings indicate the potential of finely tuned real-time comprehension tasks as measures of implicit knowledge.

Do non-native languages have an effect on word order processing in first language Turkish?

Aims and Objectives/Purpose/Research Questions: Existing studies on sentence processing in bi-/multilinguals are typically centred on the first language (L1) influence on second language sentence processing. However, there is almost no evidence of influence in the other direction. The aim of this study is to find out whether being mono-, bi-, tri- or plurilingual has an effect on reading times (RTs) in the native language. To this end, Turkish native speakers’ RTs are measured when processing Turkish canonical subject–object–verb sentences, subject–verb–object (SVO) sentences where constituents move to post-verbal positions and SVO– ki sentences where post-verbal constituents are base generated. Design/Methodology/Approach: A non-cumulative self-paced reading task is used in order to measure the RTs of a sentence. The area of interest contains (i) the critical verb, (ii) the verb of the complement clause and (iii) the argument or adjunct of the complement clause (32 sentences + 12 filler sentences). All elements are matched according to their frequency of occurrence and their syllable structure. Data and Analysis: Analyses of variance are performed on RTs of the area of interest. Findings/Conclusions: One of the main findings in this study is that all three sentence types are processed significantly slower by the monolingual group than by the bi- and multilingual groups. We infer that non-native languages have a positive effect on processing the word order in the L1, which might lead to a faster processing in the three sentence types. The findings are discussed in terms of working memory and the “gap-driven strategy”. Originality and Significance/Implications: The results are interpreted from psycholinguistic and syntactic points of view.

Processing Efficiency of L2 Collocations in Sentence Comprehension: From a Self-paced Reading Task for Japanese EFL Learners

Can L2 sentence processing strategies be native-like? Evidence from English speakers’ L2 processing of Chinese base-generated-topic sentences

This article reports on an empirical study examining English speakers’ L2 processing of Chinese base-generated-topic (BGT) sentences. Forty-four highly proficient English-speaking L2 learners of Chinese and 23 native Chinese speakers were involved in the study. Results of a self-paced reading task reveal that both native Chinese speakers’ and L2 Chinese learners’ processing of Chinese BGT sentences is syntactically induced in a top-down manner. English speakers are sensitive to and are able to make use of syntactic cues as well as semantic information in their processing of Chinese BGT sentences. The study provides disconfirming evidence against the Shallow Structure Hypothesis (Clahsen and Felser, 2006a,b), which predicts that unlike native speakers, L2 learners do not rely on structure-based processing strategies when solving ambiguities in L2 sentence processing.

Goals and strategies influence lexical prediction during sentence comprehension

Predictive processing is a critical component of language comprehension, but exactly how and why comprehenders generate lexical predictions remains to be determined. Here, we present two experiments suggesting that lexical prediction is influenced by top-down comprehension strategies, and that lexical predictions are not always generated automatically as a function of the preceding context. In Experiment 1 (N = 24), participants read predictable and unpredictable sentence-final words while EEG was recorded from the scalp. When comparing two different sets of task instructions, the neural effects of cloze probability were enhanced when predictive processing was emphasized. In Experiment 2 (N = 252), participants read predictable and unpredictable sentence continuations in a self-paced reading task, and the overall validity of predictive cues was manipulated across groups using a separate set of filler sentences. There was a linear relationship between the benefits of a constraining sentence context and the global validity of predictive cues. Critically, no reading time benefits were observed as prediction validity approached zero. These results provide important constraints for theories of anticipatory language processing, while calling into question prior assumptions about the automaticity of lexical prediction.

Abstract knowledge versus direct experience in processing of binomial expressions

We ask whether word order preferences for binomial expressions of the form A and B (e.g. bread and butter) are driven by abstract linguistic knowledge of ordering constraints referencing the semantic, phonological, and lexical properties of the constituent words, or by prior direct experience with the specific items in questions. Using forced-choice and self-paced reading tasks, we demonstrate that online processing of never-before-seen binomials is influenced by abstract knowledge of ordering constraints, which we estimate with a probabilistic model. In contrast, online processing of highly frequent binomials is primarily driven by direct experience, which we estimate from corpus frequency counts. We propose a trade-off wherein processing of novel expressions relies upon abstract knowledge, while reliance upon direct experience increases with increased exposure to an expression. Our findings support theories of language processing in which both compositional generation and direct, holistic reuse of multi-word expressions play crucial roles.

Processing Chinese relative clauses: An investigation of second-language learners from different learning contexts

AbstractThe goal of this study is to examine the processing of Chinese relative clauses (RCs) through a self-paced reading task and to determine whether the learning environment plays a role in the second-language (L2) acquisition of RCs. We investigated two types of RCs (subject vs. object RCs) along with two positions in which a RC can occur (modifying a matrix subject noun phrase [NP] vs. a matrix object NP). Eighteen native speakers of Chinese and twenty-one L2 learners at an intermediate proficiency level participated in the study. Ten learners were students learning Chinese in the US (i. e., in a foreign-language context), whereas the other eleven learners were students studying Chinese in China (i. e., in a study-abroad context). The comprehension of sentences containing a RC and reading times (RTs) on the RC and the head noun (the segment immediately following the RC) were analyzed. The results show distinct patterns for the learners and the native speakers. The accuracy data reveals that the L2 learners in China performed better than the L2 learners in the US. Additionally, the L2 learners in China exhibited a processing speed advantage to the L2 learners in the US. The RT data highlighted important asymmetries in the L2 learners in the US and the native speakers, while the results were flat for the L2 learners in China. Specifically, L2 learners in the US took longer to read object RCs than subject RCs while the opposite pattern was obtained for the L1 speakers. Moreover, matrix-object-modifying RCs revealed shorter RTs than matrix-subject-modifying RCs for L2 learners in the US, whereas the opposite pattern was found for the L1 speakers. These findings are discussed in light of the Linear Distance Theory and the Structural Distance Theory (e. g., O’Grady 1997.Syntactic development. Chicago: University of Chicago Press). Overall, these results seem to provide support to the assumption that changes in syntactic processing happen as a result of exposure to the language environment (Cuetos et al. 1996. Parsing in different languages. In Manuel Carreias, Jose E. Garcia-Albea & Nuria Sebastien-Galles (eds.),Language processing in Spanish, 145–187. Mahwah, NJ: Erlbaum; Frenck–Mestre 2002. An on-line look at sentence processing in the second language. In Roberto Heredia & Jeanette Altarriba (eds.),Bilingual sentence processing, 217–236. Amsterdam: Elsevier Science Publishers.).

That noun phrase may be beneficial and this may not be: discourse cohesion in reading and writing

This paper examines the effects of attended and unattended demonstratives on text processing, comprehension, and writing quality in two studies. In the first study, participants (n = 45) read 64 mini-stories in a self-paced reading task and identified the main referent in the clauses. The sentences varied in the type of demonstratives (i.e., this, that, these, and those) contained in the sentences and whether the referent was followed by a demonstrative determiner and noun (i.e., an attended demonstrative) or a demonstrative pronoun (i.e., an unattended demonstrative). In the second study, 173 persuasive essays written by high school students were rated by expert judges on overall writing quality using a standardized rubric. Expert coders manually counted the number and types of demonstratives (attended and unattended demonstratives) in each essay. These counts were used to predict the human scores of essay quality. The findings demonstrate that the use of unattended demonstratives as anaphoric references is disadvantageous to both reading time and referent identification. However, these disadvantages become advantages in terms of essay quality likely because linguistic complexity is a strong indicator of high proficiency writing. From a text processing and comprehension viewpoint, the findings indicate, then, that anaphoric reference is not always beneficial and does not always create a more cohesive text. In contrast, from a writing context, the use of unattended demonstratives leads to a more linguistically complex text, which generally equates to a higher quality text.

Gender matters: From L1 grammar to L2 semantics

The study investigates the effects of grammatical gender on bilingual processing. Native speakers of Russian (a gendered language) learning English and monolingual English controls performed a self-paced reading task in English (a non-gendered language). As predicted, bilingual speakers showed delayed latencies to gendered pronouns (he or she) that were incongruent with the noun's grammatical gender in Russian, indicating that first language (L1) grammatical gender assignment can be interpreted as biological gender in nonnative (L2) processing. The L1 gender bias was only found in sentences containing animate, but not inanimate, nouns. These results speak against the syntactic mechanism being solely responsible for gender biases, but rather support a semantic transfer account due to coactivation of linguistic and conceptual features as proposed in the sex and gender hypothesis (SAGH, Vigliocco, Vinson, Paganelli & Dworzynski, 2005). Overall, the study provides clear evidence for the L1 grammatical gender bias in bilingual processing, albeit constrained by animacy.

Testing the Role of Expectation in L2 Processing of English RCs

Two major explanations for the difficulty of processing object RCs (e.g., The professor that the student criticized went on vacation in Texas.) make two different predictions about where the difficulty first appears. The memory-based account predicts difficulty at the relative clause verb (i.e., criticized), while the expectation-based account predicts difficulty at the onset of the noun phrase within the object RC (i.e., the of the student). To examine why L2 learners had the relative difficulty of processing object RCs, the current study thus examines the two predictions with a sentence continuation and a self-paced reading task in experiments conducted with Korean L2 learners of English. The results show that the learners experienced difficulty processing object RCs at the relative clause verb, but not at the onset of the noun phrase. This finding suggests that English L2 learners’ memory limitations, but not their expectations, explain the difficulty they experience in processing English object RCs

Silent Reading Fluency and Comprehension in Bilingual Children.

This paper focuses on reading fluency by bilingual primary school students, and the relation of text fluency to their reading comprehension. Group differences were examined in a cross-sectional design across the age range when fluency is posed to shift from word-level to text-level. One hundred five bilingual children from primary grades 3, 4, and 5 were assessed for English word reading and decoding fluency, phonological awareness, rapid symbol naming, and oral language proficiency with standardized measures. These skills were correlated with their silent reading fluency on a self-paced story reading task. Text fluency was quantified using non-linear analytic methods: recurrence quantification and fractal analyses. Findings indicate that more fluent text reading appeared by grade 4, similar to monolingual findings, and that different aspects of fluency characterized passage reading performance at different grade levels. Text fluency and oral language proficiency emerged as significant predictors of reading comprehension.

Encouraging prediction during production facilitates subsequent comprehension: Evidence from interleaved object naming in sentence context and sentence reading.

Many studies have shown that a supportive context facilitates language comprehension. A currently influential view is that language production may support prediction in language comprehension. Experimental evidence for this, however, is relatively sparse. Here we explored whether encouraging prediction in a language production task encourages the use of predictive contexts in an interleaved comprehension task. In Experiment 1a, participants listened to the first part of a sentence and provided the final word by naming aloud a picture. The picture name was predictable or not predictable from the sentence context. Pictures were named faster when they could be predicted than when this was not the case. In Experiment 1b the same sentences, augmented by a final spill-over region, were presented in a self-paced reading task. No difference in reading times for predictive versus non-predictive sentences was found. In Experiment 2, reading and naming trials were intermixed. In the naming task, the advantage for predictable picture names was replicated. More importantly, now reading times for the spill-over region were considerable faster for predictive than for non-predictive sentences. We conjecture that these findings fit best with the notion that prediction in the service of language production encourages the use of predictive contexts in comprehension. Further research is required to identify the exact mechanisms by which production exerts its influence on comprehension.

Training and Timing Local Scalar Enrichments under Global Pragmatic Pressures

Elementary sentences containing the quantificational determiner some seem to be ambiguous between a ‘weak’ existential meaning ∃ and a ‘strengthened’ some but not all meaning ∃+. The strengthened meaning is commonly assumed to be the output of a general enrichment mechanism, call it G (for ‘global’), that applies to the weak meaning of the sentence: G(∃) = ∃+. The application of G has been shown to come with a processing cost (e.g., Bott and Noveck 2004). We used a self-paced reading task together with offline comprehension questions to investigate the interpretation of sentences containing some when embedded inside a disjunction, a position that G cannot access. Our findings suggest (i) that the strengthened meaning ∃+ is available in embedded positions, suggesting that a mechanism of local strengthening L must be available: L(∃) = ∃+, (ii) that local enrichment can be facilitated by global pragmatic pressures (Chierchia et al. 2008, Mayr and Romoli 2014), (iii) that subjects can be quickly trained to systematically prefer one of G or L to the other, (iv) that application of L, like the application of G, comes with a processing cost. We highlight consequences of our findings for debates about the characterization of enrichment mechanisms, focussing on the relation between G and L. ∗We thank Amir Anvari, Danny Fox, Lyn Frazier, Ted Gibson, Roni Katzir, Jacopo Romoli, Benjamin Spector, Ida Toivonen, Shravan Vasishth, Ken Wexler, and audiences at MIT, XPrag 2013, AMLaP 2014, and TOM 6 at McGill University.

THE FINE-TUNING OF LINGUISTIC EXPECTATIONS OVER THE COURSE OF L2 LEARNING

This study investigates the degree to which native-English-speaking learners of Spanish can generate expectations for information likely to occur in upcoming portions of an unfolding linguistic signal. We examine Spanish clitic left dislocation, a long-distance dependency between a topicalized object and an agreeing clitic, whose felicity depends on the discourse. Using a self-paced reading task, we tested the predictions of the shallow structure hypothesis (Clahsen & Felser, 2006a, 2006b) and the reduced ability to generate expectations hypothesis (Grüter, Rohde, & Schafer, 2014). Learners successfully demonstrated sensitivity to the violation of expectations set up by the syntactic and discourse context. In addition, the behavior of the second language (L2) learners was dependent on proficiency: the higher their proficiency, the more their behavior mirrored native-speaker processing. These results support a view of SLA in which knowledge of L2 discourse-grammatical relationships is acquired slowly over the course of L2 learning.

Processing Coordinate Subject-Verb Agreement in L1 and L2 Greek.

The present study examines the processing of subject-verb (SV) number agreement with coordinate subjects in pre-verbal and post-verbal positions in Greek. Greek is a language with morphological number marked on nominal and verbal elements. Coordinate SV agreement, however, is special in Greek as it is sensitive to the coordinate subject's position: when pre-verbal, the verb is marked for plural while when post-verbal the verb can be in the singular. We conducted two experiments, an acceptability judgment task with adult monolinguals as a pre-study (Experiment 1) and a self-paced reading task as the main study (Experiment 2) in order to obtain acceptance as well as processing data. Forty adult monolingual speakers of Greek participated in Experiment 1 and a hundred and forty one in Experiment 2. Seventy one children participated in Experiment 2: 30 Albanian-Greek sequential bilingual children and 41 Greek monolingual children aged 10–12 years. The adult data in Experiment 1 establish the difference in acceptability between singular VPs in SV and VS constructions reaffirming our hypothesis. Meanwhile, the adult data in Experiment 2 show that plural verbs accelerate processing regardless of subject position. The child online data show that sequential bilingual children have longer reading times (RTs) compared to the age-matched monolingual control group. However, both child groups follow a similar processing pattern in both pre-verbal and post-verbal constructions showing longer RTs immediately after a singular verb when the subject was pre-verbal indicating a grammaticality effect. In the post-verbal coordinate subject sentences, both child groups showed longer RTs on the first subject following the plural verb due to the temporary number mismatch between the verb and the first subject. This effect was resolved in monolingual children but was still present at the end of the sentence for bilingual children indicating difficulties to reanalyze and integrate information. Taken together, these findings demonstrate that (a) 10–12 year-old sequential bilingual children are sensitive to number agreement in SV coordinate constructions parsing sentences in the same way as monolingual children even though their vocabulary abilities are lower than that of age-matched monolingual peers and (b) bilinguals are slower in processing overall.

VALIDATING GRAMMATICALITY JUDGMENT TESTS

Several previous factor-analytic studies on the construct validity of grammaticality judgment tests (GJTs) concluded that untimed GJTs measure explicit knowledge (EK) and timed GJTs measure implicit knowledge (IK) (Bowles, 2011; R. Ellis, 2005; R. Ellis & Loewen, 2007). It has also been shown that, irrespective of the time condition chosen, GJTs’ grammatical sentences tap into IK, whereas their ungrammatical ones invoke EK (Gutiérrez, 2013). The current study examined these conclusions by employing two more fine-grained measures of IK: that is, a self-paced reading task and a word-monitoring task. The results of a confirmatory factor analysis revealed that manipulating GJTs’ time conditions and/or the grammaticality of the sentences does not render them distinct measures of EK and IK. The current work shows that GJTs are too coarse to be measures of IK, and that the different types of GJTs measure different levels of EK.

Cross-linguistic differences affect late Chinese-English learners on-line processing of English tense and aspect

Aims: The present study aimed to explore how varied cross-linguistic differences affect late Chinese-English learners’ on-line processing of tense and aspect in English. Methodology: We used the self-paced reading task (Experiment 1) and the eye-tracking technique (Experiment 2) to test the above question. Data and analysis: Reading times in Experiment 1 and first-fixation duration, and gaze time in Experiment 2 in four interested positions were analysed in R by ANOVAs and t-tests. Findings: Both high- and low-proficiency participants showed their sensitivity to the violation of progressive, which is nearly congruent between English and Chinese. Only high-proficiency participants were sensitive to the violation of past tense, which is similar but not congruent between Chinese and English. With regard to present third person singular, which is incongruent between Chinese and English, high-proficiency participants also showed their sensitivity to its violation; however, this sensitivity is only detected by the eye-tracking method (Experiment 2). These results suggested that cross-linguistic differences affect late second language learners’ on-line processing of English tense and aspect. Originality: To the best of our knowledge, this study is the first one exploring varied cross-linguistic differences’ influence on late Chinese-English learners’ on-line processing of tense and aspect in English. Significance: Our results provide new evidence to support the Performance Deficit Account.
