Greek-Cypriot learners’ perception and production of L2 English vowels

Acquiring L2 segments is particularly challenging for L2 learners, especially when the L1 and L2 inventories involve different contrasts and acoustic cues. The present research investigated the perception and production of L2 English vowels by adult Greek-Cypriot learners and examined the effects of orthographic cues and consonantal context in their performance. Perceptual performance was assessed through a forced-choice identification task and production performance through a wordlist-reading and an elicitation task, both analyzed acoustically and through intelligibility ratings. The findings showed the influence of the L1 on both the perception and production of L2 segments, supporting the assumptions of current models of speech perception and production. Learners faced challenges in perceiving the members of L2 contrasts and mostly used their L1 articulatory routines in their productions of L2 vowels. Orthographic cues or consonantal context did not significantly affect learners’ productions or overall perception, although strong contextual effects were observed in individual target vowels. This study is the first to provide an in-depth comparison of CYG and English vowels as well as an examination of the acquisition of L2 English vowels by this population, which can guide EFL teachers and course developers in developing appropriate EFL curricula that incorporate pronunciation instruction.

Comparative analyses of the information content of letters, characters, and inter-word spaces across writing systems.

One difference among writing systems is how orthographic cues are used to demarcate words; although most alphabetic scripts use inter-word spaces, some Asian scripts do not explicitly mark word boundaries (e.g., Chinese). It is unclear whether these differences are arbitrary or whether they are designed to maximize reading efficiency. Here, we show that spaces inserted between words in non-demarcated scripts provide less information about word boundaries than spaces in demarcated scripts. Furthermore, despite the fact that less information is contained by inter-word spaces than characters/letters of the same size, the information content of inter-word spaces in demarcated scripts is closer to that of characters/letters compared to the information content of inter-word spaces that are inserted in non-demarcated scripts. These results suggest that the conventions used to demarcate word boundaries are sufficient to support efficient reading. Our findings provide new insights into the universals and variation across writing systems and shed light on the mental processes that support skilled reading.

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.

Individual differences in L2 listening proficiency revisited: Roles of form, meaning, and use aspects of phonological vocabulary knowledge

Abstract The present study revisits the differential roles of form, meaning, and use aspects of phonological vocabulary knowledge in L2 listening proficiency. A total of 126 Japanese English-as-a-foreign-language listeners completed the TOEIC Listening test, working memory and auditory processing tests, the Metacognitive Awareness Listening Questionnaire, and several tasks designed to tap into three broad aspects of phonological vocabulary knowledge: (1) the ability to access phonological forms without any orthographic cues (phonologization), (2) the ability to recognize words regardless of the talker (generalization), and (3) the ability to determine the semantic and collocational appropriateness of words in global contexts in a fast and stable manner (automatization). Whereas the perceptual, cognitive, and metacognitive variables made relatively small contributions to L2 listening proficiency (0.4%–21.3%), the vocabulary factors explained a large amount of the variance (77.6%) in the full regression model (R2 = .507). These large lexical effects uniquely derived from the three different aspects of phonological vocabulary knowledge—automatization (55.3%), phonologization (20.8%), and generalization (1.5%). The findings suggest that successful L2 listening skill acquisition draws on not only various levels of phonological form-meaning mapping (phonologization, generalization) but also the spontaneous and robust retrieval of such vocabulary knowledge in relation to surrounding words (automatization).

Orthographic influence in the distributional learning of non-native speech sounds

This study investigated the role of orthographic information in the acquisition of non-native speech sounds by monolingual English listeners. Two potentially important orthographic variables were explored: Orthographic compatibility (whether the orthographic information supports or contradicts the distributional information) and orthographic familiarity (whether the native and target languages share the same orthography). Ten groups of learners were trained on either a unimodal or bimodal distribution of two length continua. Out of the 10 groups, eight groups were also exposed to orthographic cues that varied in their compatibility with the distributional information (compatible vs. incompatible) and familiarity with the orthography of learners’ native language (Roman vs. Arabic). Following training, all participants performed an AX discrimination task to test their discrimination of the length contrast. The results revealed that, in general, the availability of either familiar or unfamiliar orthographic input which signaled the existence of a single length category significantly lowered learners’ discrimination of the length contrast regardless of the auditory distribution. Further, the exposure to orthographic input that supported a two-category length distinction enhanced the discrimination of the length contrast irrespective of the distribution. However, the most significant improvement occurred when both distributional information and familiar orthographic input were compatible. Overall, these findings indicate that orthographic input, regardless of its level of compatibility or familiarity, may influence the acquisition of non-native speech sounds.

Form to meaning mapping and the impact of explicit morpheme combination in novel word processing

In the present study, we leveraged computational methods to explore the extent to which, relative to direct access to semantics from orthographic cues, the additional appreciation of morphological cues is advantageous while inducing the meaning of affixed pseudo-words. We re-analyzed data from a study on a lexical decision task for affixed pseudo-words. We considered a parsimonious model only including semantic variables (namely, semantic neighborhood density, entropy, magnitude, stem proximity) derived through a word-form-to-meaning approach (ngram-based). We then explored the extent to which the addition of equivalent semantic variables derived by combining semantic information from morphemes (combination-based) improved the fit of the statistical model explaining human data. Results suggest that semantic information can be extracted from arbitrary clusters of letters, yet a computational model of semantic access also including a combination-based strategy based on explicit morphological information better captures the cognitive mechanisms underlying human performance. This is particularly evident when participants recognize affixed pseudo-words as meaningful stimuli.

Sensitivity to word endings as probabilistic orthographic cues to lexical stress among English as second language learners.

Assigning stress to polysyllabic words is a crucial aspect of reading aloud in English. Previous research demonstrated that native English speakers are sensitive to word endings as probabilistic orthographic cues to stress assignment. However, little is known about if second language (L2) learners of English are sensitive to word endings as cues to lexical stress. The current study investigated whether native Chinese-speakers learning English as a second language (ESL) are sensitive to word endings as probabilistic orthographic cues to lexical stress. Our ESL learners demonstrated sensitivity to word endings as cues in a stress-assignment task and a naming task. With the increase in language proficiency, ESL learners responded more accurately in the stress-assignment task. Moreover, stress position and language proficiency moderated the strength of the sensitivity, with a trochaic bias and better proficiency leading to better sensitivity in the stress-assignment task. However, as language proficiency increased, participants' naming speed became faster in iambic but slower in trochaic patterns, reflecting the learners' fledgling knowledge about the specific stress patterns associated with varying orthographic cues, especially in a demanding naming task. Taken together, the evidence from our ESL learners fits in the proposed statistical learning mechanism, that is, L2 learners are able to implicitly extract statistical regularities from linguistic materials, the orthographic cues to lexical stress in our study. Stress position and language proficiency both play a role in developing this sensitivity.

Lateralized reading in the healthy brain: A behavioral and computational study on the nature of the visual field effect

Despite its widespread use to measure functional lateralization of language in healthy subjects, the neurocognitive bases of the visual field effect in lateralized reading are still debated. Crucially, the lack of knowledge on the nature of the visual field effect is accompanied by a lack of knowledge on the relative impact of psycholinguistic factors on its measurement, thus potentially casting doubts on its validity as a functional laterality measure. In this study, an eye-tracking-controlled tachistoscopic lateralized lexical decision task (Experiment 1) was administered to 60 right-handed and 60 left-handed volunteers and word length, orthographic neighborhood, word frequency, and imageability were manipulated. The magnitude of visual field effect was bigger in right-handed than in left-handed participants. Across the whole sample, a visual field-by-frequency interaction was observed, whereby a comparatively smaller effect of word frequency was detected in the left visual field/right hemisphere (LVF/RH) than in the right visual field/left hemisphere (RVF/LH). In a subsequent computational study (Experiment 2), efficient (LH) and inefficient (RH) activation of lexical orthographic nodes was modelled by means of the Naïve Discriminative Learning approach. Computational data simulated the effect of visual field and its interaction with frequency observed in the Experiment 1. Data suggest that the visual field effect can be biased by word frequency. Less distinctive connections between orthographic cues and lexical/semantic output units in the RH than in the LH can account for the emergence of the visual field effect and its interaction with word frequency.

Orthographic processing of proper Names: A proposal to investigate the orthographic cue for second language readers

A standard treatment of proper names in second language (L2) vocabulary analyses is to categorize them as known items. This treatment is often supported by the assumption that the form of the proper name (i.e., the initial capital letter) and the context will indicate to the L2 reader that the item is a proper name. The aim of this work-in-progress report is to propose a methodological approach for investigating the claim that form facilitates proper name recognition for L2 readers, in particular for those whose first language (L1) employs a different orthography and writing system than English. While previous research has looked at the orthographic processing of proper names for L1 users, a gap exists in the literature for L2 readers. The assumption that L2 readers are skilled at identifying proper names from the initial capital warrants investigation as there are implications for the processing load in both pedagogical and testing situations. A proposed method to investigate the initial capital letter as a cue for L2 English proper name recognition is a name decision task, a variation on a lexical decision task, using English proper names and common nouns that are familiar to Japanese participants. Reaction times and error percentages to proper names with case type as a factor (i.e., initial capital letter or all lowercase) will be submitted to a linear mixed effects analysis.

A commentary on four papers in the second language vocabulary learning strand for the JALT Vocabulary SIG

In this commentary, the following four papers have been reviewed and discussed: Vocabulary Learning Outside of the Classroom: Institutional Use of a Spaced Repetition Vocabulary Learning App (Mueller & Hays, 2022), Developing a Discipline-Specific Corpus and High-Frequency Word List for Science and Engineering Students in the Graduate School (Uehara et al., 2022), Rasch-based Instrument Validations for an Augmented Reality Vocabulary Acquisition Experiment (Dabrowski, 2022), and Orthographic Processing of Proper Names: A Proposal to Investigate the Orthographic Cue for Second Language Readers (Klassen, 2022).

Doubling up: The Influence of Native and Foreign Language Cues in Foreign Language Double Consonant Spelling

In this study, we investigated which spelling cues are used in word-medial consonant spelling by learners of English as a Foreign Language (EFL). Previous research has shown that native speakers of English rely on different cues to decide whether a single (“diner”) or double consonant (“dinner”) needs to be used in word-medial consonant spelling. These cues include phonology, orthography, morphology and lexical frequency. We investigated whether these cues play a similar role in Dutch spellers who are EFL learners, next to similarity of the English target to Dutch. We analyzed dictation task data that was part of an unsupervised digital learning environment for EFL learning. The error analyses revealed that novice EFL spellers mainly used phonological and cross-linguistic cues in consonant doubling. In contrast, more proficient spellers relied less on phonological cues, and relied on morphological cues instead. The EFL spellers did not rely on orthographic cues. Furthermore, spelling difficulty was influenced by the frequency of a word and its similarity with the native-language equivalent, in terms of cognate status (non-cognate/cognate) and consonant doubling. Together, our findings indicate that a higher number of converging cues facilitates spelling for EFL spellers and that their reliance on cues changes as spelling proficiency increases.

Korean-english Bilingual Children's Stress Cue Sensitivity and its Relationship with Reading in English.

Lexical stress plays a critical role in multisyllabic word reading in English. However, assignment of English lexical stress, which is neither fixed nor marked in writing, can pose significant challenges for English learners and has not been well-understood. The present study aims to fill the research gap by studying sensitivity to lexical stress cues and its contribution to their word reading performance among young English-language learners whose first language is Korean. The fundamental differences in prosodic systems between Korean and English provide theoretical significance of studying how bilingual children having no lexical stress in their first language process English lexical stress. This study focuses on two major cues to English lexical stress: morphological and orthographic cues. Findings revealed that the participants are sensitive to the two stress cues, with better performance with orthographic cues to stress assignment. However, no statistically significant correlations were found among variables on stress cue sensitivity with those on reading.

Orthography does not hinder non-native production learning in children

Children are known to be fast learners due to their neural plasticity. Learning a non-native language (L2) requires the mastering of new production patterns. In classroom settings, learners are not only exposed to the acoustic input, but also to the unfamiliar grapheme–phoneme correspondences of the L2 orthography. We tested how 9–10-year-old children, with Finnish as a native language (L1), respond to a two-day listen-and-repeat training paradigm, where they simultaneously hear acoustic stimuli and see orthographic cues. In the procedure, non-words containing the L2 vowel /ʉ/ were presented simultaneously with an orthographic cue showing <u>, guiding pronunciation towards the L1 vowel /u/ according to Finnish grapheme–phoneme correspondences. Earlier studies showed that Finnish adults rely on the orthographic cue over the acoustic one, leading them to produce /u/ instead of /ʉ/ when presented with the incongruent L1–L2 grapheme–phoneme correspondence (<u> – L1: /u/, L2: /ʉ/). Also, an earlier result from age-matched children receiving only acoustic input showed relatively fast pronunciation changes towards the target vowel. Our present results indicate clear and fast production learning of the non-native sound, and the misleading orthographic cue did not draw attention away from the target acoustic form. With orthographic cues, the participants learned to produce novel sounds faster than without them.

Resting-State Functional Connectivity following Phonological Component Analysis: The Combined Action of Phonology and Visual Orthographic Cues.

Anomia is the most frequent and pervasive symptom for people with aphasia (PWA). Phonological component analysis (PCA) is a therapy incorporating phonological cues to treat anomia. Investigations of neural correlates supporting improvements following PCA remain scarce. Resting-state functional connectivity (rsFC) as a marker of therapy-induced neuroplasticity has been reported by our team. The present study explores the efficacy of PCA in French and associated therapy-induced neuroplasticity using whole-brain rsFC analysis. Ten PWA participated in a pre-/post-PCA fMRI study with cognitive linguistic assessments. PCA was delivered in French following the standard procedure. PCA led to significant improvement with trained and untrained items. PCA also led to changes in rsFC between distributed ROIs in the semantic network, visual network, and sub-cortical areas. Changes in rsFC can be interpreted within the frame of the visual and phonological nature of PCA. Behavioral and rsFC data changes associated with PCA in French highlight its efficacy and point to the importance of phonological and orthographic cues to consolidate the word-retrieval strategy, contributing to generalization to untrained words.

THE IMPACT OF ORTHOGRAPHY ON LEXICAL ACCESS

AbstractPrevious research has shown that orthographic marking may have a function beyond identifying orthographic word forms. In two visual priming experiments with native speakers and advanced learners of German (Czech natives) we tested the hypothesis that orthography can convey word-class cues comparable to morphological marking. We examined the effect of initial letter capitalization of nouns (a specific property of German orthography) on the processing of five homonymous and grammatically ambiguous forms. Both populations showed the same pattern of results: deverbal nouns (conversions) patterned together with countable nouns while in a previous study (with eliminated orthographic word-class cues) they patterned together with infinitives. Together, findings suggest that orthographic cues can trigger word-class-specific lexical retrieval/access. They also suggest a lexical entry structure in which conversion nouns, infinitives, and inflected verbal forms share a category-neutral parent node and that specified subnodes are accessed only when specifying cues are available and/or necessary for processing.

The role of orthographic cues to stress in Italian visual word recognition

In this study, stress diacritics were used to investigate the processing of stress information in lexical decision. We ran two experiments in Italian, a language in which stress position is not predictable by rule and only final stress—that is, the less common pattern—is orthographically marked with a diacritic. In Experiment 1, a lexical decision task, two factors were manipulated: the stress pattern of words—antepenultimate (nondominant) and penultimate (dominant)—and the presence/absence of the diacritics, signalling the stress position. Participants were faster to categorise stimuli as words when they bear dominant than nondominant stress. However, the advantage disappeared when the diacritic was used. In Experiment 2, a same-different verification task was used in which participants had to decide if a referent word and a target were same (carota-CAROTA, /ka’rɔta/; tavolo-TAVOLO, /’tavolo/) or different. We compared two conditions requiring a “different” response, in which referent and target with dominant and nondominant stress were congruent (caròta-CAROTA; tàvolo-TAVOLO) or incongruent (càrota-CAROTA; tavòlo-TAVOLO) with the word’s stress. For words with dominant stress, “different” responses were faster in the incongruent condition than the congruent condition. This congruency effect was not observed for words with nondominant stress pattern. Overall, the data suggest that stress information is based on lexical phonology, and the stress dominance effect has a lexical base in word recognition.

Sensitivity to meaningful regularities acquired through experience

English spelling provides multiple cues to word meaning, and these cues are readily exploited by skilled readers. In two crowdsourcing studies, we tested skilled readers’ sensitivity to a large number of morphological as well as nonmorphological orthographic cues by asking them to classify nonwords as adjectives or nouns. We observed a substantial variability across individuals and orthographic cues. In this paper, we discuss some sources of this variation. Specifically, we found consistent correlations between readers’ sensitivity to cues and their performance on language tasks (reading, spelling, and author recognition tests) suggesting that reading experience is critical for assimilating spelling-to-meaning regularity from written language. Further, we identified characteristics that may be important for the learning and exploitation of orthographic cues that are related to the nature of their function and use in context.

Dynamic relationships between phonological memory and reading: A five year longitudinal study from age 4 to 9.

We reconcile competing theories of the role of phonological memory in reading development, by uncovering their dynamic relationship during the first 5years of school. Phonological memory, reading and phoneme awareness were assessed in 780 phonics-educated children at age 4, 5, 6 and 9. Confirmatory factor analyses demonstrated that phonological memory loaded onto two factors: verbal short-term memory (verbal STM; phonological tasks that loaded primarily on serial order memory) and nonword repetition. Using longitudinal structural equation models, we found that verbal STM directly predicted early word-level reading from age 4 to 6, reflecting the importance of serial-order memory for letter-by-letter decoding. In contrast, reading had no reciprocal influence on the development of verbal STM. The relationship between nonword repetition and reading was bidirectional across the 5years of study: nonword repetition and reading predicted each other both directly and indirectly (via phoneme awareness). Indirect effects from nonword repetition (and verbal STM) to reading support the view that phonological memory stimulates phonemically detailed representations through repeated encoding of complex verbal stimuli. Similarly, the indirect influence of reading on nonword repetition suggests that improved reading ability promotes the phoneme-level specificity of phonological representations. Finally, the direct influence from reading to nonword repetition suggests that better readers use orthographic cues to help them remember and repeat new words accurately.
