When bases compete: A voting model of lexical conservatism

Abstract: This article examines lexical conservatism (Steriade 1997), a phenomenon whereby the distribution of stem allomorphs in a morphological paradigm influences the way that paradigm accommodates derived members. Specifically, a phonological alternation applies in a derived member only if an existing form is present elsewhere in the paradigm that offers the needed phonological material. Thus illústrable undergoes stress shift because the existing word illústrative contains the illústr- stem allomorph. In contrast, * irrígable is judged worse than írrigable , since there is no existing form in * irríg- . In four experiments with speakers of English and Mexican Spanish, I demonstrate that this dependency between paradigm structure and application of phonological processes generalizes to entirely novel words in a probabilistic manner. Further, I find that a broad range of stem allomorphs in a paradigm play a role in determining the form of the novel word, rather than only those that could reduce the markedness of the novel form, contra previous studies. I propose a novel grammatical model where bases get to ‘vote’ on the shape of the novel form: all stem allomorphs in a lexical entry stand in a correspondence relation to the novel form and exert their influence via multiple faithfulness constraints, which compete with standard markedness constraints in a probabilistic phonological grammar.

K’abeena phonology

The article provides descriptive analysis of the phonology of K'abeena, a language belonging to the Afro-Asian phylum, spoken in central Ethiopia. In this article, I identify 25 consonant phonemes and 3 loan phonemes. The loan phonemes are included as they are used in the current language's orthography. The language has five vowels. Vowel length and Gemination of consonants are phonemic in the language. With the exception of /h/ and /f/, which never geminate in the language, the rest of the consonant phonemes appear together to geminate. This only happens in the medial position of the words. Consonant clusters are allowed in word medial position with a maximum of two consonants. The phonological process identified in this article involves processes like assimilation, palatalization and deletion. Kabeena does not appear to be a pitch-accent language, but further research is needed to establish confirmed statements.

Do children with developmental dyslexia have syntactic awareness problems once phonological processing and memory are controlled?

IntroductionSyntactic awareness is the ability to monitor and manipulate word order within sentences. It is unclear whether children with dyslexia have syntactic awareness problems, as there are mixed results in the literature. Dyslexia is typically classified with very poor word and nonword reading and phonological processing problems are often observed in this population. It is conceivable that a phonological deficit could strain memory when performing oral syntactic awareness tasks. Here we examine if syntactic awareness problems are observed in children with dyslexia once phonological processing and memory skills are controlled.MethodsReal and nonword reading efficiency tests determined reading level. Children with dyslexia (n = 25) were compared to typically developing children (n = 24) matched for age (M = 8;8) and nonverbal abilities. Syntactic awareness was measured with an oral word order correction task (e.g., Is baking Lisa and her son in his room sleeps). Tests of phonological awareness, phonological memory, and verbal working memory were also administered and served as controls.ResultsThe dyslexic group performed worse than typically developing readers on syntactic awareness and this group difference persisted once phonological memory and verbal working memory were controlled. However, after controlling for phonological awareness skills, there were no group differences on the syntactic awareness test.Discussion:The results suggest that phonological awareness problems in particular might be responsible for syntactic awareness difficulties in dyslexia and future studies should control for this. The results are discussed within theoretical frameworks on the nature of oral language deficits in dyslexia.

Exploring Performance Skills in the Occupation of Learning to Read

ABSTRACT Only one-third of U.S. fourth-grade public school students score at or above reading proficiency on national standardized tests. Current language-based reading instruction methods do not appear to meet many students’ needs. This study explores the role of visual perception in word recognition skills amongst typically developing first graders. It is hypothesized that visual perception is a crucial component of word recognition. This quantitative correlational study explored the relationship between visual perception and word recognition skills in first grade students participating in general education. The findings revealed that several statistically significant relationships exist between visual perceptual functions and skills recruited for word recognition. Phonological processing is strongly associated with spatial relations (r = .35) and sequential memory (r = .38). These correlations are significant at the 0.01 level (2-tailed). Form constancy (r = .28) p < .05 is significant at the 0.05 level (2-tailed). These relationships suggest that visual perceptual skills and phonological processing are concurrently developed in these participants and that these skills are likely recruited simultaneously when engaging in occupations, such as learning to read. This study highlights the role of visual perception in early reading development. Educators may consider consulting with school-based occupational therapists to explore the potential impact of visual perception when supporting students who struggle with reading.

Phonological processing in Chinese word repetition: Dementia effect and age effect

ABSTRACT This paper examined phonological processing as reflected in Mandarin word and non-word repetition. Issues related to dementia effects, age effects, and linguistic variables are discussed. Forty-five speakers of Mandarin Chinese in Taiwan took part in this study. Fourteen seniors with Alzheimer’s disease (AD), 14 healthy adults, and 17 healthy seniors individually completed a task of word repetition. Scores of accurate repetition were calculated, and error types as well as error frequency were analysed. Linguistic variables, including lexicality, frequency, non-word, and syllable length, were discussed. Major findings were indicative of a significant dementia effect, in which participants with AD were significantly impaired in repeating words with more syllables, specifically 5-syllable non-words of low frequency. Numerous significant age effects were noted. Theoretical implications and directions for future study are discussed.

Effects of Lexical Properties in L2 Chinese Compound Processing: A Multivariate Approach.

Previous studies on L2 (i.e., second language) Chinese compound processing have focused on the relative efficiency of two routes: holistic processing versus combinatorial processing. However, it is still unclear whether Chinese compounds are processed with multilevel representations among L2 learners due to the hierarchical structure of the characters. Therefore, taking a multivariate approach, the present study evaluated the relative influence and importance of different grain sizes of lexical information in an L2 Chinese two-character compound decision task. Results of supervised component generalized linear regression models with random forests analysis revealed that the orthographic, phonological and semantic information all contributed to L2 compound processing, but the L2 learners used more orthographic processing strategies and fewer phonological processing strategies compared to the native speakers. Specifically, the orthographic information was activated at the whole-word, the character and the radical levels in orthographic processing, and the phonological information at the whole-word, the syllable, and the phoneme levels all exerted contributions in phonological processing. Furthermore, the semantic information of the whole words and the constituents was accessed in semantic processing. These findings together suggest that the L2 learners are able to use cues at all levels simultaneously to process Chinese compound words, supporting a multi-route model with a hierarchical morphological structure in such processing.

Opacity in classic and derivational optimality theory: Tiberian Hebrew Spirantization and Polisho-Raising

Classic Optimality Theory treats phonological computation as a one-step parallel evaluation of output candidates. Such an approach does not handle well phonological opacity, in which the context of phonological processes is obscured on the surface. This article shows two examples of phonological opacity: Tiberian Hebrew Spirantization and Polish o-Raising. While these mappings are impossible to account for in classic OT, they are readily analyzed using the framework of Derivational OT.

Parafoveal Processing of Orthography, Phonology, and Semantics during Chinese Reading: Effects of Foveal Load.

The foveal load hypothesis assumes that the ease (or difficulty) of processing the currently fixated word in a sentence can influence processing of the upcoming word(s), such that parafoveal preview is reduced when foveal load is high. Recent investigations using pseudo-character previews reported an absence of foveal load effects in Chinese reading. Substantial Chinese studies to date provide some evidence to show that parafoveal words may be processed orthographically, phonologically, or semantically. However, it has not yet been established whether parafoveal processing is equivalent in terms of the type of parafoveal information extracted (orthographic, phonological, semantic) under different foveal load conditions. Accordingly, the present study investigated this issue with two experiments. Participants' eye movements were recorded as they read sentences in which foveal load was manipulated by placing a low- or high-frequency word N preceding a critical word. The preview validity of the upcoming word N + 1 was manipulated in Experiment 1, and word N + 2 in Experiment 2. The parafoveal preview was either identical to word N + 1(or word N + 2); orthographically related; phonologically related; semantically related; or an unrelated pseudo-character. The results showed robust main effects of frequency and preview type on both N + 1 and N + 2. Crucially, however, interactions between foveal load and preview type were absent, indicating that foveal load does not modulate the types of parafoveal information processed during Chinese reading.

Developing a Dyslexia Diagnostic Team: A Feasibility Project

Purpose: Dyslexia, a neurobiological phonological processing deficit, can be identified early; however, there is a substantial variation between and within states regarding who makes this diagnosis and when. Dyslexia evaluations are often challenging to obtain and very expensive for families who need to seek them outside of the school setting. The purpose of this study was to determine the feasibility of developing a free dyslexia diagnostic team within our university speech and hearing clinic. Method: We developed a team of academic and clinical faculty and students at the doctoral, master's, and undergraduate levels. We developed a 6-hr (1 day) testing battery and recruited families via social media. Children needed to be between the ages of 8 and 11 years and reported to have classroom difficulty related to word reading and/or spelling. Results: We were able to create a strong and successful team, testing battery, and recruitment plan. Master's students were interested in the opportunity and families drove between 246 and 453 miles to participate. We allocated enough time in our summer schedule for all parties. However, we have concerns about the sustainability of this program, especially during the academic year. Conclusions: Broadly, this dyslexia diagnostic team is a feasible endeavor. There was internal and external community interest. We identified small and solvable barriers related to debriefing and test interpretation. We also identified larger issues related to funding, faculty availability, and student support.

Through the Lens of Struggle: An Inquiry into the Reading Difficulties of Secondary High School Learners

This research, adopting a Phenomenological approach, focuses on understanding the challenges students encounter in comprehending, decoding, and processing written information. Grounded in G. Reid Lyon's Phonological Processing Deficit Theory, introduced in the 1990s, the study aims to uncover the struggles of secondary high school learners facing reading difficulties. Data were gathered through In-Depth Interview and Focused-group Discussion among secondary teachers. Content thematic analysis was used to craft the main themes. Lived experiences on the struggles of secondary high school learners with reading difficulties were: reading difficulties in secondary learners, weak vocabulary and language skills, comprehension issues, learning disabilities, lacking reading motivations, difficulty with reading instruction, and technology distractions. Coping mechanisms were coined to the following themes: time management, active reading strategies, and multimodal learning resources. And finally, educational Insights that can be drawn to Mitigate reading difficulties of secondary learners: teaching approach and recognition of diverse learners, and effective encouragement through access to books and empowering tools. In the future, DepEd plans a comprehensive policy for reading difficulties, prioritizing tailored teacher training, diverse resources, and continuous support for an inclusive environment, while research informs policy and innovative education approaches.

Exploring Contrastive Learning Neural-Congruency on EEG Recording of Children with Dyslexia

Electroencephalogram (EEG) recordings of children are often used to study the underlying neural basis of causal factors of reading disorders and dyslexia. However, the inter-subject variability in EEG and the unconstrained nature of reading experiments used to elicit these factors made it challenging for traditional EEG analysis methods to extract neural components of these factors. In this work, we aim to explore the use of novel deep neural network architectures and contrastive learning methods to overcome the methodological limitations of traditional techniques and enhance the extraction process of neural components during reading tasks. Notably, we formulate a neural network architecture to extract EEG embedding using contrastive loss that maximizes the neural congruency in non-dyslexic children compared to children with dyslexia. We plan to evaluate our approach on three EEG datasets involving children with dyslexia performing Rapid Automatized Naming (RAN) and Phonological Processing (PA) tasks. The proposed contrastive learning framework will provide an enhanced tool to facilitate studying the neural underpinnings of naming speed and their association with reading performance and related difficulties.

Language impairment in sporadic and familial (type 8) amyotrophic lateral sclerosis: A comparative study.

Language is frequently affected in patients with sporadic amyotrophic lateral sclerosis (sALS), with reduced performance in naming, syntactic comprehension, grammatical expression, and orthographic processing. However, the language profile of patients with familial type 8 ALS (ALS8), linked to p.P56S VAPB mutation, remains unclear. We investigated language in patients with ALS8 by examining their auditory comprehension and verbal production. We included three groups of participants: (1) patients with sALS (n = 20), (2) patients with familial ALS8 (n = 22), and (3) healthy controls (n = 21). The groups were matched for age, sex, and education level. All participants underwent a comprehensive language battery, including the Boston Diagnostic Aphasia Examination, the reduced Token test, letter fluency, categorical fluency (animals), word definition from the Cambridge Semantic Memory Research Battery, and a narrative discourse analysis. Participants also were evaluated using Addenbrooke's Cognitive Exam-Revised Version, the Hospital Anxiety and Depression Scale, and the ALS Functional Rating Scale-Revised. Compared to controls, sALS and ALS8 patients had impaired performance on oral (syntactic and phonological processing) comprehension and inappropriate discourse cohesion. sALS and ALS8 did not differ in any language measure. There was no correlation between language scores and functional and psychiatric scales. ALS8 patients exhibit language deficits that are independent of motor features. These findings are consistent with the current evidence suggesting that ALS8 has prominent non-motor features.

Learning to Read in an Intermediate Depth Orthography: The Longitudinal Role of Grapheme Sounding on Different Types of Reading Fluency.

Phonological processing skills, such as phonological awareness, are known predictors of reading acquisition in alphabetic languages with varying degrees of orthographic complexity. However, the role of multi-letter-sound knowledge, an important foundation for early reading development, in supporting reading fluency development remains to be determined. This study examined whether two core foundational skills, phonemic awareness and grapheme sounding, have a predictive role in reading fluency development in an intermediate-depth orthography. The participants were 62 children learning to read in European Portuguese, and they were longitudinally assessed on phonemic awareness, complex grapheme sounding, and reading fluency (decoding, word, and text) from Grade 2 to Grade 3. The results showed that grapheme sounding predicted reading fluency development controlled for nonverbal intelligence and vocabulary, short-term verbal memory, and phonemic awareness. Grapheme sounding plays a prominent role in predicting reading fluency outcomes, whereas phonemic awareness (both accuracy and time per correct item) did not contribute to any of the three types of reading fluency. The fact that grapheme-sounding predicted reading fluency is likely due to complex grapheme-phoneme correspondences being required to achieve proficient reading. These findings provide insights into the cognitive processes underlying reading development in intermediate-depth orthographies and have implications for early literacy instruction.

Functional connectivity is linked to working memory differences in children with reading learning disability

Reading learning disability (RLD) is characterized by a specific difficulty in learning to read that is not better explained by an intellectual disability, lack of instruction, psychosocial adversity, or a neurological disorder. According to the domain-general hypothesis, a working memory deficit is the primary problem. Working memory in this population has recently been linked to altered resting-state functional connectivity within the default mode network (DMN), salience network (SN), and frontoparietal network (FPN) compared to that in typically developing individuals. The main purpose of the present study was to compare the within-network functional connectivity of the DMN, SN, FPN, and reading network in two groups of children with RLD: a group with lower-than-average working memory (LWM) and a group with average working memory (AWM). All subjects underwent resting-state functional magnetic resonance imaging (fMRI), and data were analyzed from a network perspective using the network brain statistics framework. The results showed that the LWM group had significantly weaker connectivity in a network that involved brain regions in the DMN, SN, and FPN than the AWM group. Although there was no significant difference between groups in reading network in the present study, other studies have shown relationship of the connectivity of the angular gyrus, supramarginal gyrus, and inferior parietal lobe with the phonological process of reading. The results suggest that although there are significant differences in functional connectivity in the associated networks between children with LWM and AWM, the distinctive cognitive profile has no specific effect on the reading network.

How Hearing Loss and Cochlear Implantation Affect Verbal Working Memory: Evidence From Adolescents.

Verbal working memory is poorer for children with hearing loss than for peers with normal hearing (NH), even with cochlear implantation and early intervention. Poor verbal working memory can affect academic performance, especially in higher grades, making this deficit a significant problem. This study examined the stability of verbal working memory across middle childhood, tested working memory in adolescents with NH or cochlear implants (CIs), explored whether signal enhancement can improve verbal working memory, and tested two hypotheses proposed to explain the poor verbal working memory of children with hearing loss: (a) Diminished auditory experience directly affects executive functions, including working memory; (b) degraded auditory inputs inhibit children's abilities to recover the phonological structure needed for encoding verbal material into storage. Fourteen-year-olds served as subjects: 55 with NH; 52 with CIs. Immediate serial recall tasks were used to assess working memory. Stimuli consisted of nonverbal, spatial stimuli and four kinds of verbal, acoustic stimuli: nonrhyming and rhyming words, and nonrhyming words with two kinds of signal enhancement: audiovisual and indexical. Analyses examined (a) stability of verbal working memory across middle childhood, (b) differences in verbal and nonverbal working memory, (c) effects of signal enhancement on recall, (d) phonological processing abilities, and (e) source of the diminished verbal working memory in adolescents with cochlear implants. Verbal working memory remained stable across middle childhood. Adolescents across groups performed similarly for nonverbal stimuli, but those with CIs displayed poorer recall accuracy for verbal stimuli; signal enhancement did not improve recall. Poor phonological sensitivity largely accounted for the group effect. The central executive for working memory is not affected by hearing loss or cochlear implantation. Instead, the phonological deficit faced by adolescents with CIs denigrates the representation in storage and augmenting the signal does not help.

Transitioning from paper to touch interface: Phoneme-grapheme recognition testing and gamification in primary school classrooms

Phonological processing of written characters has been recognized as a crucial element in acquiring literacy in any language, both native and foreign. This study aimed to assess Japanese primary school students' phoneme-grapheme recognition skills using both paper-based and touch-interface tests. Differences between the two test formats and the relationship between phoneme-grapheme recognition skills and interaction with gamified digital tests were investigated. Participants were sixth-grade students from two public schools. The results of comparison tests indicated that the touch-interface test had lower success rates compared to the paper-based test for most items, suggesting a difference in performance patterns. A consistent relationship between tested phoneme-grapheme knowledge and successful gamified interaction was found. Findings highlight the potential of touch-interface assessments for assessing phoneme-grapheme recognition skills in primary school classrooms and suggest incorporating more digital tasks to enhance student adaptation.

Phonological awareness mediates the relationship between DCDC2 and reading performance with home environment

Proficient reading requires critical phonological processing skill that interacts with both genetic and environmental factors. However, the precise nature of the relationships between phonological processing and genetic and environmental factors are poorly understood. We analyzed data from the Genes, Reading and Dyslexia (GRaD) Study on 1419 children ages 8–15 years from African-American and Hispanic-American family backgrounds living in North America. The analyses showed that phonological awareness mediated the relationship between DCDC2-READ1 and reading outcomes when parental education and socioeconomic status was low. The association between READ1 and reading performance is complex, whereby mediation by phonological awareness was significantly moderated by both parental education and socioeconomic status. These results show the importance of home environment and phonological skills when determining associations between READ1 and reading outcomes. This will be an important consideration in the development of genetic screening for risk of reading disability.

Is the Suppliance of L2 Inflectional Morphology Subject to Covert Contrasts? An Analysis of the Production of L2 English Third Person Singular Agreement by L1 Bengali Speakers

The cause(s) of missing inflectional morphology in obligatory contexts by adult speakers of second language (L2) English is subject to ongoing discussion. Whatever the specific theory, however, the apparent asymmetrical production of the morpheme ‘-s’ in the marking of number on plural nouns versus that on third person singular agreement has to be accounted for. This study adopts the theoretical approach put forward by the Prosodic Transfer Hypothesis, whereby the prosodic representation of inflectional morphology in the first language (L1) can, to some extent, account for differences in the suppliance of inflectional morphology in L2 English within and across L1s. It is in this context that the production of third person singular agreement, and, for contrastive purposes, number on plural nouns, by L1 Bengali speakers of L2 English, is considered in relation to available prosodic representation in the L1, as well as against phonological processes attested in L1 acquisition. More specifically, covert contrasts. An inspection of spectrograms from instances of the omission of inflection by L1 Bengali speakers of L2 English at Beginner to Intermediate proficiency levels does not, however, indicate that learners are covertly supplying agreement on the third person singular (or plural number on nouns). This finding does not necessarily rule out the occurrence of covert contrasts in L2 production of inflectional morphology; alternative techniques may detect a systematic difference between bare verbs and non-audible (to the listener) inflection.

A Non-Linear Analysis of Foreign English Words in Standard Arabic

This study aimed to analyze the foreign English loanwords in Standard Arabic within the framework of a non-linear phonology (autosegmental phonology). The analysis of the data focused on selected phonological processes such as: consonantal substitutions including voicing, devoicing, velarization, fortition. Moreover, it covers the phonological process of assimilation, comprising palatalization, labialization, nasalization, and vowel harmony. Furthermore, vowel lengthening and shortening phonological processes were identified in the collected data. The sample of the study is collected from six sources: Said (1976), Zughoul and Hussein (1993), Al-Saqqa (2001), Mukkaram (2006), Salem (2015), and Abu Guba (2016). Finally, the study showed that autosegmental theory provides an adequate analysis in explaining certain phonological processes when dealing with English loanwords.

Comorbid Word Reading and Mathematics Computation Difficulty at Start of First Grade.

The purpose of this analysis was to describe cognitive processes associated with comorbid difficulty between word reading (WR) and mathematics computation (MC) at the start of first grade among children selected for WR and MC delays. A sample of 234 children (mean age 6.50 years, SD = 0.31) was assessed on WR, MC, core cognitive processes (phonological processing, rapid automatized naming, verbal counting [VC]), and domain-general cognitive processes (working memory, oral language, nonverbal reasoning, attentive behavior). Structural equation modeling was used to predict a latent Comorbidity factor, which modeled shared variance between WR and MC, and to identify processes associated with that Comorbidity factor. Results identified each of the core cognitive processes, especially VC, and each of the domain-general cognitive processes, especially working memory, as explaining shared variance between WR and MC. Implications for understanding comorbid difficulty at the start of first grade and designing coordinated first-grade interventions are discussed.
