Cross-lingual dependency parsing for a language with a unique script

Abstract Syntactic parsing is one of the areas in Natural Language Processing. The development of large-scale multilingual language models has enabled cross-lingual parsing approaches, which allows us to develop parsers for languages that do not have treebanks available. However, these approaches rely on the assumption that languages share orthographic representations and lexical entries. In this article, we investigate methods for developing a dependency parser for Xibe, a low-resource language that is written in a unique script. We first investigate lexicalized monolingual dependency parsing experiments to examine the effectiveness of word, part-of-speech, and character embeddings as well as pre-trained language models. Results show that character embeddings can significantly improve performance, while pre-trained language models decrease performance since they do not recognize the Xibe script. We also train delexicalized monolingual models, which yield competitive results to the best lexicalized model. Since the monolingual models are trained on a very small training set, we also investigate lexicalized and delexicalized cross-lingual models. We use six closely related languages as source language, which cover a wide range of scripts. In this setting, the delexicalized models achieve higher performance than lexicalized models. A final experiment shows that we can increase performance of the cross-lingual model by combining source languages and selecting the most similar sentences to Xibe as training set. However, all cross-lingual parsing results are still considerably lower than the monolingual model. We attribute the low performance of cross-lingual methods to syntactic and annotation differences as well as to the impoverished input of Universal Dependency Part-of-Speech tags that the delexicalized model has access to.

Makkan Arabic in the digital age: A sociolinguistic analysis of the representation of fricative, stop, and sibilant variation in WhatsApp text messages

This study examines Makkan Arabic speakers’ orthographic representation of standard and colloquial variants in their WhatsApp text messages. In particular, we examine the role that speaker gender, speaker age, gender composition of conversations, and topic of discussions play in Hadari Makkans’ representation of standard and colloquial variants of the variables (th), (dh), and (Dh). Statistical analyses reveal that women favor colloquial variant stops [t] and [d], while men exhibit a preference for standard variants [θ] and [ð], particularly when conversing with other men. For (Dh), however, both women and men favor the standard variant [ðˤ]. Age also plays a role in the distribution of variants, with speakers favoring standard variants as they age. The use of fricatives [θ] and [ð] also increases when participants discuss formal topics, which suggests an implicit association between standard language and formality, despite the inherent informality of WhatsApp interactions. This study provides insights into how phonological variation is orthographically represented within a written genre designed to mimic spontaneous conversation and enriches the broader discourse on Arabic language variation and digital communication.

HRT in DMC? the orthographic representation of high rising terminals in WhatsApp

Contemporary research has shown that a combination of qualitative and quantitative methods is productive in exploring patterns of Digitally Mediated Communication (DMC). In this paper, I demonstrate the analytical potential of this approach by studying the typographic representation of a prosodic feature of spoken language – High Rising Terminals (HRTs, e.g., that beer pong place I went for my birthday?) – in a large corpus of WhatsApp messages (96,471 messages; 594,183 words) sent by 15 young British adults. Combining methods and approaches from variationist and interactional sociolinguistics, I show that the orthographic representation of HRTs patterns in pragmatically similar ways to the feature in speech in that it most frequently functions as a way of verifying the interlocutors’ comprehension of discourse-new information. The precise rate and pragmatic function of this feature, however, appears to be constrained by the textual modality of the platform. Concluding, I join others in arguing for the analytical potential of employing a multidimensional approach to studying variable patterns of DMC.

Cross-modal interactions in language production: evidence from word learning.

Literate adults are able to produce the same word in different language modalities-for instance, through speaking and writing. Yet how speaking and writing interact is not well understood. The present study takes a new perspective on the question of the co-activation of phonological and orthographic representations in speaking and writing by examining the acquisition of novel words. We tested how novel words get integrated into modality-specific lexicons by biasing novel word acquisition toward speaking or writing and assessing cross-modal transfer at the first stages of learning. Participants learned novel words paired with pictures of novel objects and practiced them overtly through speaking or typing. At test, typed training led to higher recall accuracy than spoken training whether words were recalled through typing or speaking. Performance in typing (RT and durations) benefited more from typed than spoken training. Crucially, performance in speaking did not benefit specifically from spoken training and was similar after spoken or typed training. Results are compatible with an asymmetric integration in the phonological and orthographic lexicons according to the modality of training, with representations created in the orthographic lexicon directly transferring to the phonological lexicon, while the opposite doesn't seem to occur. Cross-modal transfer dynamics are discussed according to the level of lexical activation.

The importance of sublexical structure in the orthographic representation of monosyllabic words

ABSTRACT Participants judged whether a letter-string created a word when a single letter was added to the end indicated by a hyphen. Unique final fragments were easier to reconstruct when corresponding to the body of a word, having no onset (e.g. laugh from –augh) than when the second consonant of a two-letter onset was also included (e.g. blind from –lind). Conversely, unique initial fragments were easier to reconstruct when including the first consonant of a two-letter coda (e.g. drink from drin–) than when corresponding to an “antibody”, having no coda (e.g. claim from clai–). Such results cannot be explained by any account of orthographic processing based purely on the identity and position of the component letters while ignoring their function as an onset, coda, or vowel. Instead, the results are compatible with a model such as the proposed Subsyllabic Processing (SSP) account where subsyllabic structures are hierarchically represented.

Direct Retrieval of Orthographic Representations in Chinese Handwritten Production: Evidence from a Dynamic Causal Modeling Study.

This present study identified an optimal model representing the relationship between orthography and phonology in Chinese handwritten production using dynamic causal modeling, and further explored how this model was modulated by word frequency and syllable frequency. Each model contained five volumes of interest in the left hemisphere (angular gyrus [AG], inferior frontal gyrus [IFG], middle frontal gyrus [MFG], superior frontal gyrus [SFG], and supramarginal gyrus [SMG]), with the IFG as the driven input area. Results showed the superiority of a model in which both the MFG and the AG connected with the IFG, supporting the orthography autonomy hypothesis. Word frequency modulated the AG → SFG connection (information flow from the orthographic lexicon to the orthographic buffer), and syllable frequency affected the IFG → MFG connection (information transmission from the semantic system to the phonological lexicon). This study thus provides new insights into the connectivity architecture of neural substrates involved in writing.

Improving word reading skills of low‐skilled readers: An intervention combining a syllable‐based approach with digital game‐based features

AbstractBackgroundChildren with low reading skills are less frequently engaged in reading activities and therefore the likelihood of improving their reading skills decreases. Digital game‐based interventions have emerged as a promising tool for promoting reading development in children, particularly those with reading difficulties. As syllable‐based reading interventions are likely to increase word reading skills in low‐skilled readers, we developed a new reading intervention application that emphasizes syllable segmentation and integrates proven elements of digital game‐based learning. The intervention aimed to promote phonological recoding and consolidating orthographic representation of syllables.ObjectivesThe present study investigated the effects of the newly developed syllable‐based reading intervention application on general word recognition skills, phonological recoding processes, orthographic decoding processes and text‐level reading comprehension skills in German second graders.MethodsIn a quasi‐experimental design, children with low word recognition skills were randomly assigned to a treatment group (n = 66) or a wait‐list group (n = 66). General word recognition skills, phonological recoding processes, orthographic decoding processes and text‐level reading comprehension were measured with standardized German reading tests before and after the treatment group received the digital reading intervention for 20 sessions.ResultsResults indicated that the children in the treatment group showed significant improvement in general word recognition and in phonological recoding processes compared to equally low‐skilled untreated children in the wait‐list group. Orthographic decoding processes improved only in children with less severe impairments, whereas no significant improvements were found in text‐level reading comprehension.Take AwaysThe digital reading intervention is a promising approach for supporting word reading in low‐skilled reading second graders and can serve as an effective intervention tool for this target group.

Emotion effects survive non-standard orthographic representations

ABSTRACT Digital communication has generated forms of written speech that may deviate from standard ones, such as Greeklish (a Latin-alphabet-based script) vs. Greek. The question of interest is how different orthographic representations of the same referent (e.g. petaloyda, “butterfly”, in Greeklish vs. πϵταλούδα “butterfly” in Greek) may influence word processing, particularly visual word recognition and access to affective connotations. 120 Greek native speakers were tested on a lexical decision task, in which script (Greeklish vs. Greek) and valence (positive vs. negative vs. neutral) were manipulated within participants. Words were matched for word class, frequency, concreteness, length, number of syllables and orthographic neighbourhood. Emotional words differed from neutral ones in valence and arousal. Results yielded faster response times for words written in the standard script (Greek) than the non-standard script (Greeklish). Moreover, regardless of script, response times were negatively correlated with the words’ valence, with slowest responses for negative words and fastest for positive ones, suggesting that positive content accelerates lexical access, whereas negative content slows it down. To sum up, although script type was found to affect word recognition, activation of and access to emotional content seemed to resist non-standard characteristics of visual word processing.

Early cognitive predictors of spelling and reading in German-speaking children

Theoretical backgroundWhile reading and spelling skills often are interconnected in models of literacy development, recent research suggests that the two skills can dissociate and that reading and spelling are associated with at least partly different cognitive predictors. However, previous research on dissociations between reading and spelling skills focused on children who have already mastered the first phases of literacy development. These findings suggest that dissociations are due to distinct deficits in orthographic processing (i.e., unprecise orthographic representations vs. inefficient serial processing). It is therefore unclear whether dissociations already become apparent during the initial stages, or rather emerge later in development. This study aims to enhance the understanding of the predictors of early spelling and reading skills, investigating potential variations, by considering various cognitive factors beyond well-established ones.MethodsData were collected at two time points: cognitive predictors and early reading and spelling skills were assessed at the end of kindergarten (T1) before formal literacy instruction started, and reading and spelling skills were again assessed in Grade 1 (T2). The data analysis included 353 first-grade participants. Linear regression analyses assessed predictive patterns, while logistic regression analyses explained children's likelihood of belonging to different proficiency groups (at-risk or typical skills).ResultsResults revealed phonological processing, letter knowledge, and intelligence, as significant predictors for Spelling in grade 1 (T2), even after adding the autoregressor (Spelling in kindergarten at T1) and the respective other literacy skill (Reading T2). For Reading in grade 1 (T2), phonological processing, and rapid automatized naming (RAN) surfaced as significant predictors after adding the autoregressor (Reading T1). However, only RAN surfaced as a significant predictor for Reading T2 after adding the respective other literacy skill (Spelling T2). In line with these findings, logistic regression analyses revealed that phonological processing predicted group allocation for Spelling T2 and RAN predicted group allocation for Reading T2.ConclusionsOverall, the study underscores the importance of phonological processing and letter knowledge as early predictors of spelling and reading skills in Grade 1. Moreover, intelligence is identified as a predictor for early spelling, while rapid automatized naming (RAN) emerges as a predictor for early reading.

The orthographic representation of a word’s morphological structure: beneficial and detrimental effect for spellers

In this paper we present a review of the literature on the role of a word’s morphological structure in written language processing, with an emphasis on spelling. First, we describe that many orthographies have opted for a representation of a word’s morphological structure. Second, we discuss experiments that have demonstrated the importance of a word’s morphological structure in reading, both in isolated word recognition experiments (so-called blind morphological decomposition) and in reading for meaning. Third, we discuss experimental findings that the written representation of a word’s morphological structure can have beneficial effects in spelling, already in young children with a good morphological awareness. However, several experiments have also shown that, in some circumstances, the speller’s task of representing morphology in written words creates considerable challenges and causes spelling errors rather than providing assistance. Closer inspection of this dissociation between beneficial and harmful effects reveals that two factors play a crucial role in determining the error risk: (a) the distinction between stems and affixes (i.e., morphological accessibility based on semantic transparency) and (b) the frequency with which a morpheme type in a language (stem, affix) must be retrieved in writing texts (accessibility based on type and token frequency). The review offers a theoretical framework against which the other papers in this special issue can be situated.

Ortho-semantic learning of novel words: an event-related potential study of grade 3 children

IntroductionAs children become independent readers, they regularly encounter new words whose meanings they must infer from context, and whose spellings must be learned for future recognition. The self-teaching hypothesis proposes orthographic learning skills are critical in the transition to fluent reading, while the lexical quality hypothesis further emphasizes the importance of semantics. Event-related potential (ERP) studies of reading development have focused on effects related to the N170 component—print tuning (letters vs. symbols) and lexical tuning (real words vs. consonant strings)—as well as the N400 reflecting semantic processing, but have not investigated the relationship of these components to word learning during independent reading.MethodsIn this study, children in grade 3 independently read short stories that introduced novel words, then completed a lexical decision task from which ERPs were derived.ResultsLike real words, newly-learned novel words evoked a lexical tuning effect, indicating rapid establishment of orthographic representations. Both real and novel words elicited significantly smaller N400s than pseudowords, suggesting that semantic representations of the novel words were established. Further, N170 print tuning predicted accuracy on identifying the spellings of the novel words, while the N400 effect for novel words was associated with reading comprehension.DiscussionExposure to novel words during self-directed reading rapidly establishes neural markers of orthographic and semantic processing. Furthermore, the ability to rapidly filter letter strings from symbols is predictive of orthographic learning, while rapid establishment of semantic representations of novel words is associated with stronger reading comprehension.

Orthographic Learning in French-Speaking Deaf and Hard of Hearing Children.

Children are assumed to acquire orthographic representations during autonomous reading by decoding new written words. The present study investigates how deaf and hard of hearing (DHH) children build new orthographic representations compared to typically hearing (TH) children. Twenty-nine DHH children, from 7.8 to 13.5 years old, with moderate-to-profound hearing loss, matched for reading level and chronological age to TH controls, were exposed to 10 pseudowords (novel words) in written stories. Then, they performed a spelling task and an orthographic recognition task on these new words. In the spelling task, we found no difference in accuracy, but a difference in errors emerged between the two groups: Phonologically plausible errors were less common in DHH children than in TH children. In the recognition task, DHH children were better than TH children at recognizing target pseudowords. Phonological strategies seemed to be used less by DHH than by TH children who very often chose phonological distractors. Both groups created sufficiently detailed orthographic representations to complete the tasks, which support the self-teaching hypothesis. DHH children used phonological information in both tasks but could use more orthographic cues than TH children to build up orthographic representations. Using the combination of a spelling task and a recognition task, as well as analyzing the nature of errors, in this study, provides a methodological implication for further understanding of underlying cognitive processes.

Phonological syllables allow children with developmental dyslexia to access words.

Learning to read is a middle-distance race for children worldwide. Most of them succeed in this acquisition with "normal" difficulties that ensue from the progressive (re)structuring of the phonological and orthographic systems. Evidence accumulated on reading difficulties in children with developmental dyslexia (DYS children, henceforth) shows a pervasive phonological deficit. However, the phonological deficit may not be due to degraded phonological representations but rather due to impaired access to them. This study focused on how and to what extent phonological syllables, which are essential reading units in French, were accessible to DYS children to segment and access words. We tested the assumption that DYS children did not strictly have pervasive degraded phonological representations but also have impaired access to phonological and orthographic representations. We administered a visually adapted word-spotting paradigm, engaging both sublexical processing and lexical access, with French native-speaking DYS children (N = 25; Mage in months = 121.6, SD = 3.0) compared with chronological age-matched peers (N = 25; Mage in months = 121.8, SD = 2.7; CA peers henceforth) and reading level-matched peers (N = 25; Mage in months = 94.0, SD = 4.6; RL peers henceforth). Although DYS children were slower and less accurate than CA and RL peers, we found that they used phonological syllables to access and segment words. However, they exhibit neither the classical inhibitory syllable frequency effect nor the lexical frequency effect, which is generally observed in typically developing children. Surprisingly, DYS children did not show strictly degraded phonological representations because they demonstrated phonological syllable-based segmentation abilities, particularly with high-frequency syllables. Their difficulties are rather interpreted in terms of impaired access to orthographic and phonological representations, which could be a direct effect of difficulties in generalizing and consolidating low-frequency syllables. We discuss these results regarding reading acquisition and the specificities of the French linguistic system.

When more is more: effect of context and stimulus set size on orthographic learning

ABSTRACT Orthographic learning was measured over two experiments after adults trained words written with unfamiliar symbols. Participants were randomly assigned to read a set of either 24 or 86 target words, both in context and in isolation. Training took place over six trials, followed by delayed reading and spelling post-tests. Reading in context consistently bolstered reading accuracy during and after training. In contrast, the highest spelling scores were noted following reading in isolation. The number of words to be learned (stimulus set size) moderated the effects of isolation training. Self-teaching a large set of diverse words in isolation increased reading accuracy, closing the gap with context. Overall, training in context helped establish orthographic representations that were good enough to support reading accuracy, especially when training with a small set of words. Whereas, reading in isolation refined orthographic representations to be precise enough to support later spelling accuracy.

NSP-SCD: A corpus construction protocol for child-directed print in understudied languages

Child-directed print corpora enable systematic psycholinguistic investigations, but this research infrastructure is not available in many understudied languages. Moreover, researchers of understudied languages are dependent on manual tagging because precise automatized parsers are not yet available. One plausible way forward is to limit the intensive work to a small-sized corpus. However, with little systematic enquiry about approaches to corpus construction, it is unclear how robust a small corpus can be made. The current study examines the potential of a non-sequential sampling protocol for small corpus development (NSP-SCD) through a cross-corpora and within-corpus analysis. A corpus comprising 17,584 words was developed by applying the protocol to a larger corpus of 150,595 words from children’s books for 3-to-10-year-olds. While the larger corpus will by definition have more instances of unique words and unique orthographic units, still, the selectively sampled small corpus approximated the larger corpus for lexical and orthographic diversity and was equivalent for orthographic representation and word length. Psycholinguistic complexity increased by book level and varied by parts of speech. Finally, in a robustness check of lexical diversity, the non-sequentially sampled small corpus was more efficient compared to a same-sized corpus constructed by simply using all sentences from a few books (402 books vs. seven books). If a small corpus must be used then non-sequential sampling from books stratified by book level makes the corpus statistics better approximate what is found in larger corpora. Overall, the protocol shows promise as a tool to advance the science of child language acquisition in understudied languages.

Developing Chinese lexical representations in Korean learner’s mind

Aims and objectives/purpose/research questions: The present research explores whether Korean learners of Chinese at different proficiency levels employ distinct processing strategies when processing Chinese words with identical or different orthographic representations. Design/methodology/approach: In this research, two experimental studies were carried out to examine how Korean learners with different Chinese language proficiency process orthography, pronunciation, and meanings of Chinese written words. Data and analysis: Reaction times and error rates were analyzed for each study. Revised hierarchical model (RHM) and Ontogenesis Model (OM) are the major models used to analyze and discuss the results. Findings/conclusions: The findings of the phonological task reveal that intermediate-level participants utilize first language mediators to access second language (L2) words, whereas high-level participants can directly activate L2 phonological representations without first language interference. Conversely, in the semantic task, participants from both proficiency levels seem to adopt the word association model regardless of orthographic representations. Originality: The originality of the present study lies in its examination of the processing strategies employed by Korean learners of Chinese at different proficiency levels, specifically when processing Chinese words with identical or different orthographic representations. Significance/implications: These findings suggest that L2 proficiency does not guarantee the elimination of native language influence on L2 lexical processing and various factors can affect L2 lexical processing. To improve L2 lexical learning, it is recommended to start language learning early, increase vocabulary size, and enhance exposure to L2 words.

Modelling orthographic similarity effects in recognition memory reveals support for open bigram representations of letter coding

A variety of letter string representations has been proposed in the reading literature to account for empirically established orthographic similarity effects from masked priming studies. However, these similarity effects have not been explored in episodic memory paradigms and very few memory models have employed orthographic representation of words. In the current work, through two recognition memory experiments employing word and pseudoword stimuli respectively, we empirically established a set of key orthographic similarity effects for the first time in recognition memory – namely the substitution effect, transposition effect and reverse effect in recognition memory of words and pseudowords, and a start-letter importance in recognition memory of words. Subsequently, we compared orthographic representations from the reading literature including slot coding, closed-bigram, open-bigram and the overlap model. Each of these representations was situated in a global matching model and fitted to recognition performance via Luce’s choice rule in a hierarchical Bayesian framework. Model selection results showed support for the open-bigram representation in both experiments.

An eye movement study on the mechanisms of reading fluency development

Little is known about how word recognition processes, such as decoding, change when reading fluency improves during the school year. Such knowledge may have practical importance by determining which aspects of reading are most malleable at a certain age and reading level. The development of word-recognition subprocesses of third- and fourth-grade Finnish students (n = 81) with variable reading fluency was explored from longitudinal (6-month) text reading eye-tracking data. Generic development of the word recognition system was assessed from longitudinal changes in first fixation, average refixation durations and the number of first-pass fixations. The development of orthographic word representations and decoding was studied by examining the longitudinal changes in word frequency and word length effects, respectively. According to the results, the gain in reading fluency was mainly associated with decreases in first fixation and refixation durations. These decreases, in turn, inhibited the reduction in the number of fixations. However, students who could overcome this inhibitory effect, that is, by reading both with shorter fixation durations and with fewer fixations, developed most in reading fluency. The results seem to indicate that reading fluency development is driven by increased efficiency in representing letter strings in working memory. Over time, this development may lead to fewer fixations made into a word and, thus, more letters processed during each fixation.

Inter- and Intra- Hemispheric Interactions in Reading Ambiguous Words

The present study investigated how the brain processes words with multiple meanings. Specifically, we examined the inter- and intra-hemispheric connectivity of unambiguous words compared to two types of ambiguous words: homophonic homographs, which have multiple meanings mapped to a single phonological representation and orthography, and heterophonic homographs, which have multiple meanings mapped to different phonological representations but the same orthography. Using a semantic relatedness judgment task and effective connectivity analysis via Dynamic Causal Modeling (DCM) on previously published fMRI data (Bitan et al., 2017), we found that the two hemispheres compete in orthographic processing during the reading of unambiguous words. For heterophonic homographs, we observed increased connectivity within the left hemisphere, highlighting the importance of top-down re-activation of orthographic representations by phonological ones for considering alternative meanings. For homophonic homographs, we found a flow of information from the left to the right hemisphere and from the right to the left, indicating that the brain retrieves different meanings using different pathways. These findings provide novel insights into the complex mechanisms involved in language processing and shed light on the different communication patterns within and between hemispheres during the processing of ambiguous and unambiguous words.
