Linear and nonlinear processing of Hebrew templatic words: the role of metalinguistic awareness

Abstract While universal linguistic theories advocate linear processing of words across languages, psycholinguistic research of Semitic templatic words supports the nonlinear processing into the root and template, mainly due to semantic specifications related to the root and the morphological awareness needed in the tasks. The present study examined whether the root and template affect the word processing of Hebrew native speakers due to metalinguistic awareness regardless of semantics. We designed an auditory rhyme judgment task, a phonological awareness test that requires linear processing and reduces semantics. The task included Hebrew CVCVC templatic word pairs comprising varying root and template phonemes, transposed-phoneme roots emphasizing phonological cooccurrence restrictions, and identical phoneme roots accentuating lexical-syntactic information pronounced in the vocalic melody templates. Findings revealed low accuracy rates in rhyming pairs, particularly those with accentuated linguistic information, indicating distraction from linear processing. However, the accuracy distributions among participants and between and within the stimulus types showed that linear processing also occurred. These results suggest that both linear and nonlinear processing modes are accessible to native Hebrew speakers. The study aligns with models of the mental lexicon proposing dynamic language processing influenced by both linguistic and non-linguistic factors, highlighting the idiosyncratic nature of word processing strategies.

The role of sound-to-symbol literacy in phonological awareness: Evidence from Cantonese

Phonological awareness reflects linguistic knowledge related to the sound system of a language. Individual development of phonological awareness is known to progress from larger to smaller sized units and is promoted by the acquisition of literacy, especially in alphabet-based writing systems that are built around sound-to-symbol correspondences. The present study addressed the nature of phonological awareness in speakers of a logographically scripted language. It investigated phonological awareness in adult speakers of Cantonese hailing from Hong Kong who (compared to speakers of other logographically scripted languages) traditionally received little sound-based assistance from tools like Pinyin or Zhu-yin-Fu-Hao when they acquired orthography. The study adopted an individual difference approach, quantifying individually variable levels of experience with a sound-to-symbol writing system and their relationship to phonological awareness. Fifty-seven Hong-Kong speakers of Cantonese took part online, completing rhyme judgment and phoneme monitoring tasks, alongside an extensive background questionnaire. The main prediction that Cantonese speakers who had a relatively high level of experience with sound-to-symbol writing would show an advantage in phonological awareness at the subsyllabic level was largely borne out by the data. The findings of the present study suggest that phonological awareness is a complex set of dissociable skills, shaped by the linguistic and orthographic experience of individual speakers.

Effect of levels-of-processing on rates of forgetting.

The levels-of-processing (LOP) framework, proposing that deep processing yields superior retention, has provided an important paradigm for memory research and a practical means of improving learning. However, the available levels-of-processing literature focuses on immediate memory performance. It is assumed within the LOP framework that deep processing will lead to slower forgetting than will shallow processing. However, it is unclear whether, or how, the initial level of processing affects the forgetting slopes over longer retention intervals. The present three experiments were designed to explore whether items encoded at qualitatively different LOP are forgotten at different rates. In the first two experiments, depth of processing was manipulated within-participants at encoding under deep and shallow conditions (semantic vs. rhyme judgement in Experiment 1; semantic vs. consonant-vowel pattern decision in Experiment 2). Recognition accuracy (d prime) was measured between-participants immediately after learning and at 30-min, 2-h, and 24-h delays. The third experiment employed a between-participants design, contrasting the rates of forgetting following semantic and phonological (rhyme) processing at immediate, 30-min, 2-h, and 6-h delays. Results from the three experiments consistently demonstrated a large effect size of levels of processing on immediate performance and a medium-to-large level effect size on delayed recognition, but crucially no LOP × delay group interaction. Analysis of the retention curves revealed no significant differences between the slopes of forgetting for deep and shallow processing. These results suggest that the rates of forgetting are independent of the qualitatively distinct encoding operations manipulated by levels of processing.

Not Everybody Has an Inner Voice: Behavioral Consequences of Anendophasia

It is commonly assumed that inner speech—the experience of thought as occurring in a natural language—is a human universal. Recent evidence, however, suggests that the experience of inner speech in adults varies from near constant to nonexistent. We propose a name for a lack of the experience of inner speech—anendophasia—and report four studies examining some of its behavioral consequences. We found that adults who reported low levels of inner speech (N = 46) had lower performance on a verbal working memory task and more difficulty performing rhyme judgments compared with adults who reported high levels of inner speech (N = 47). Task-switching performance—previously linked to endogenous verbal cueing—and categorical effects on perceptual judgments were unrelated to differences in inner speech.

Measuring Inner Speech Objectively and Subjectively in Aphasia

ABSTRACT Background Many people with aphasia and people without brain injury talk to themselves in their heads, i.e., have “inner speech.” Inner speech may be more preserved compared with spoken speech for some people with aphasia and may serve a variety of functions (e.g., emotion regulation), which motivates us to provide a high-fidelity characterization of it. Researchers have used multiple methods to measure this internal phenomenon in the past, which we combine here for the first time in a single study. Aims We compare performance between individuals with and without aphasia on inner speech tasks that assess inner speech “in-the-moment” to general subjective impressions of inner speech to tease apart the relationship of aphasia severity to inner speech. Methods and Procedures Twenty people with mild-moderate aphasia and twenty neurotypical controls completed several inner speech tasks, including objective silent rhyme judgements (picture, written, and auditory), subjective reports of inner speech during naming, and subjective rating scales about inner speech experience more generally. Outcomes and Results In-the-moment inner speech during silent rhyming tasks was associated with aphasia severity only for picture and written rhyming but not auditory rhyming. In-the-moment inner speech reports during silent naming were not associated with aphasia severity, nor were the subjective ratings about general inner speech experience. Individuals with and without aphasia demonstrated a variety of subjective general inner speech experiences, demonstrating heterogeneity of this phenomenon more broadly. Conclusions Methods of measuring inner speech complement each other and speak to different facets of the inner speech phenomenon, and clinicians and researchers must carefully choose the method(s) that will provide the information about inner speech that they desire.

Hebrew-L2 speakers process auditory templatic words through their L1 processing mechanism with awareness of L2.

Bilingualism involves cross-linguistic influence (CLI) prompted by communicative function, which impacts the activation of the bilingual's L1/L2 language processing mechanisms. The current study examines the extent of CLI when semantic information is reduced. Semitic languages are known for their templatic words composed of intertwined sub-lexical root and template morphemes, entailing non-linear morphological processing. As the roots constitute the semantic core, comprehension was found to impact morphological processing among Hebrew-L2 readers. Herein, we assessed the processing mechanism activated among adult Hebrew-L2 bilinguals in an auditory rhyme judgment task that requires linear processing. The task was provided with Hebrew templatic word pairs comprising accentuated (meta)linguistic information irrespective of semantics: phonological co-occurrence restrictions (root), grammatical information of vocalic melodies (template), and contrastive stress. We hypothesized that CLI in Hebrew-L2 speakers would be reflected in low accuracy rates in rhyming pairs when linguistic information is accentuated, indicating distraction from the linear processing due to activation levels of the L2 processing mechanism caused by competing linguistic cues drawn on transferred linguistic information. We compared the performance of 58 adult Hebrew native speakers with 54 Hebrew-L2 speakers with Semitic and non-Semitic-L1. The findings demonstrate that Hebrew-L2 speakers performed the task using their L1 processing mechanism with varying activation levels of L2, showing awareness of the morphological processing due to the vocalic melody for non-Semitic-L1 and awareness of contrastive stress for Semitic-L1. The results confirm CLI also when semantics is reduced, elucidating how much CLI modulates the bilingual's language processing mechanism.

Does MOED Rhyme with FRUIT? An event-related potential study of cross-language rhyming.

The study aimed to characterize the event-related potentials signature elicited by visual rhyme judgements across two alphabetic orthographies that differ in depth (shallow: Dutch; deep: English) and by spelling-sound consistency in a deep L2-English orthography. Twenty-four Dutch-English bilinguals who varied on measures of L2-English proficiency, made rhyme judgments of semantically unrelated Dutch-English word pairs presented sequentially in the visual modality, while behavioral and electrophysiological responses were recorded. The spelling-sound consistency of target words was varied systematically. Nonrhyming targets elicited a larger N450 amplitude than rhyming targets, indicating sensitivity to mismatching phonology across languages. English target words with consistent spelling-sound mappings elicited less negative N250 amplitudes when preceded by rhyming Dutch primes. Overall, event-related potentials revealed robust responses to phonological mismatch, but subtle responses to spelling-sound inconsistency in L2-English. Results suggest that bilingual readers of a shallow L1 orthography who are immersed in an L1-speaking environment may not tune into the degree of spelling-sound consistency of a deep L2 orthography.

Effects of orthographic transparency on rhyme judgement.

This study investigated the influence of multiliteracy in opaque orthographies on phonological awareness. Using a visual rhyme judgement task in English, we assessed phonological processing in three multilingual and multiliterate populations who were distinguished by the transparency of the orthographies they can read in (N = 135; ages 18-40). The first group consisted of 45 multilinguals literate in English and a transparent Latin orthography like Malay; the second group consisted of 45 multilinguals literate in English and transparent orthographies like Malay and Arabic; and the third group consisted of 45 multilinguals literate in English, transparent orthographies, and Mandarin Chinese, an opaque orthography. Results showed that all groups had poorer performance in the two opaque conditions: rhyming pairs with different orthographic endings and non-rhyming pairs with similar orthographic endings, with the latter posing the greatest difficulty. Subjects whose languages consisted of half or more opaque orthographies performed significantly better than subjects who knew more transparent orthographies than opaque orthographies. The findings are consistent with past studies that used the visual rhyme judgement paradigm and suggest that literacy experience acquired over time relating to orthographic transparency may influence performance on phonological awareness tasks.

Musical training alters neural processing of tones and vowels in classic Chinese poems

Long-term rigorous musical training promotes various aspects of spoken language processing. However, it is unclear whether musical training provides an advantage in recognizing segmental and suprasegmental information of spoken language. We used vowel and tone violations in spoken unfamiliar seven-character quatrains and a rhyming judgment task to investigate the effects of musical training on tone and vowel processing by recording ERPs. Compared with non-musicians, musicians were more accurate and responded faster to incorrect than correct tones. Musicians showed larger P2 components in their ERPs than non-musicians during both tone and vowel processing, revealing increased focused attention on sounds. Both groups showed enhanced N400 and LPC for incorrect vowels (vs. correct vowels) but non-musicians showed an additional P2 effect for vowel violations. Moreover, both groups showed enhanced LPC for incorrect tones (vs. correct tones) but only non-musicians showed an additional N400 effect for tone violations. These results indicate that vowel/tone processing is less effortful for musicians (vs. non-musicians). Our study suggests that long-term musical training facilitates speech tone and vowel processing in a tonal language environment by increasing the attentional focus on speech and reducing demands for detecting incorrect vowels and integration costs for tone changes.

Case Report: Neural correlates of orthographic congruency effects in auditory rhyme judgment in two stroke survivors

ABSTRACT Background Auditory rhyme judgment has been widely used as an index of phonological processing in people with aphasia (PWA). However, healthy, literate adults experience orthographic interference during phonological tasks such as auditory rhyme judgment, a byproduct of skilled reading and crossmodal connections forged during reading acquisition. This orthographic interference is an indicator that orthographic representations are active during phonological processing. Therefore, the potential for orthographic interference in auditory rhyme judgments in PWA may indicate that performance on such tasks is supported by stored graphophonemic representations, rather than specifically indexing phonological processing. Method Using event related potentials (ERPs), we examined orthographic congruency effects in auditory rhyme judgment in two stroke survivors, one with moderate nonfluent aphasia and apraxia of speech, and one with mild nonfluent aphasia and apraxia of speech. The two stroke survivors and nine healthy comparison participants completed an auditory rhyme judgment task in four conditions (rhyming and non-rhyming, with congruent and incongruent orthography). Results ERP results showed the N400 rhyming and orthographic congruency effects for both stroke survivors and the comparison group even though words were not presented visually. Conclusion The results of this case report indicate that orthographic representations are active during auditory rhyme judgment in the two stroke survivors, similar to comparison participants. Thus, auditory rhyme judgment tasks may be supported by orthographic representations and therefore may not index solely phonological processing, but rather crossmodal graphophonemic representations.

Bilingual phonological awareness as a function of language proficiency

Aims and objectives: The present study examined whether phonological awareness reflects a stable construct or whether it varies by the different languages of bilingual speakers. In particular, the study tests to what extent language proficiency determines phonological awareness above and beyond language structural characteristics. Methodology: Bilingual adult speakers were tested as they afford within-participant comparisons to address this issue. Specifically, 29 Hebrew (L1)-English (L2) bilinguals were compared to 33 English (L1)-Hebrew (L2) bilinguals on a timed auditory rhyme judgment task including 270 word-pairs (90 English pairs, 90 Hebrew pairs, and 90 pseudo-Hebrew pairs). Data and analysis: Reaction times and dʹ on the rhyme judgment task were compared between the two bilingual groups to examine the role of language proficiency in predicting phonological awareness performance. Furthermore, rhyme judgments on Hebrew pairs were correlated with those on English pairs to provide within-participant index of phonological awareness stability. Findings: Rhyme judgment performance on the same set of words was affected by the strength of linguistic representations, as determined by language proficiency profile. English-Hebrew bilinguals performed better on English pairs, whereas Hebrew-English bilinguals performed better on Hebrew pairs. Moreover, within-group comparisons revealed that performance in the more proficient language was not correlated with performance in the less proficient language. Originality: By testing two groups of bilinguals who differ in their language dominance profile using the same set of materials (including both L1 and L2 pairs), the results reveal differences in phonological awareness abilities as a function of language proficiency that cannot be reduced to structural differences between the examined languages. Significance: The findings underscore the dynamic nature of phonological awareness abilities and carry implications for clinical diagnosis of bilingual populations, in that rhyme judgment performance in one language should not be taken to index expected abilities in the other language of bilingual speakers.

Distinct neural correlates of poor decoding and poor comprehension in children with reading disability.

Reading disability (RD) can manifest itself as a word decoding problem or a reading comprehension problem. In the current study, we identified 3 subtypes of RD: poor decoders (PD), poor comprehenders (PC), and poor-in-both (PB). We found that PD had greater deficits in meta-linguistic skills such as phonological awareness, orthographic skills, and morphological skills than PC, whereas PC had greater deficits in listening comprehension than PD. In the brain, we also found different patterns of deficits during an auditory rhyming judgment task using functional magnetic resonance imaging. PD showed less activation than PC and age controls in the left dorsal inferior frontal gyrus (IFG) and pre-supplementary motor area (SMA), brain activation of which was correlated with phonological awareness and working memory. In contrast, PC showed less activation in the left fusiform gyrus than PD and age controls, which was correlated with reading comprehension fluency and morphological skill. Last, PB showed both PD's and PC's deficits, as well as additional deficits in the bilateral lingual gyri. Our findings contribute to revealing different neural signatures of poor decoding and poor comprehension, which are distinct disorders but co-occur very often. These findings implicate possibility and necessity of precise diagnosis and individualized intervention.

A Diffusion Tensor Imaging Study on the White Matter Structures Related to the Phonology in Cantonese-Mandarin Bilinguals.

Cantonese and Mandarin are logographic languages, and the phonology is the main difference between the two languages. It is unclear whether the long-term experience of Cantonese–Mandarin bilingualism will shape different brain white matter structures related to phonological processing. A total of 30 Cantonese–Mandarin bilinguals and 30 Mandarin monolinguals completed diffusion-weighted imaging scan and phonological processing tasks. The tractography and tract-based spatial statistics were used to investigate the structural differences in the bilateral superior longitudinal fasciculus (SLF), inferior longitudinal fasciculus (ILF), and inferior fronto–occipital fasciculus (IFOF) between Cantonese–Mandarin bilinguals and Mandarin monolinguals. The post-hoc correlation analysis was conducted to investigate the relationship between the different structures with phonological processing skills. Compared to the Mandarin monolinguals, the Cantonese–Mandarin bilinguals had higher fractional anisotropy (FA) along the left ILFs higher mean diffusivity (MD) along the right IFOF and the temporoparietal segment of SLF (tSLF), higher axial diffusivity (AD) in the right IFOF and left ILF, and lower number of streamlines in the bilateral tSLF. The mean AD of the different voxels in the right IFOF and the mean FA of the different voxels in the left ILF were positively correlated with the inverse efficiency score (IES) of the Cantonese auditory and Mandarin visual rhyming judgment tasks, respectively, within the bilingual group. The correlation between FA and IES was different among the groups. The long-term experience of Cantonese–Mandarin bilinguals shapes the different brain white matter structures in tSLF, IFOF, and ILF. Compared to the monolinguals, the bilinguals’ white matter showed higher diffusivity, especially in the axonal direction. These changes were related to bilinguals’ phonological processing.

The efficacy of grapheme-phoneme correspondence instruction in reducing the effect of orthographic forms on second language phonology

AbstractThe orthographic forms (spellings) of second language (L2) words and sounds affect the pronunciation and awareness of L2 sounds, even after lengthy naturalistic exposure. This study investigated whether instruction could reduce the effects of English orthographic forms on Italian native speakers’ pronunciation and awareness of L2 English sounds. Italians perceive, produce, and judge the same sound as a short sound if it is spelled with one letter and as a long sound if it is spelled with a digraph, due to L1 Italian grapheme-phoneme correspondence (GPC) rules whereby double consonant letters represent long consonants. Totally, 100 Italian learners of English were allocated to two conditions (finaln= 88). The participants in the explicit GPC (EGPC) condition discovered English GPC rules relating to sound length through reflection, explicit teaching, and practice; the participants in the passive exposure condition practiced the same words as the EGPC participants, but with no mention of GPCs. Pre- and postintervention production (delayed word repetition) and phonological awareness (rhyme judgment) tasks revealed no positive effects of the instruction. GPC instruction appears to be ineffective in reducing orthographic effects on L2 phonology. Orthographic effects may be impervious to change, whether by naturalistic exposure or by instruction.

Infants' Implicit Rhyme Perception in Child Songs and Its Relationship With Vocabulary.

Rhyme perception is an important predictor for future literacy. Assessing rhyme abilities, however, commonly requires children to make explicit rhyme judgements on single words. Here we explored whether infants already implicitly process rhymes in natural rhyming contexts (child songs) and whether this response correlates with later vocabulary size. In a passive listening ERP study, 10.5 month-old Dutch infants were exposed to rhyming and non-rhyming child songs. Two types of rhyme effects were analysed: (1) ERPs elicited by the first rhyme occurring in each song (rhyme sensitivity) and (2) ERPs elicited by rhymes repeating after the first rhyme in each song (rhyme repetition). Only for the latter a tentative negativity for rhymes from 0 to 200 ms after the onset of the rhyme word was found. This rhyme repetition effect correlated with productive vocabulary at 18 months-old, but not with any other vocabulary measure (perception at 10.5 or 18 months-old). While awaiting future replication, the study indicates precursors of phonological awareness already during infancy and with ecologically valid linguistic stimuli.

The role of phonological and semantic representations in verbal short-term memory and delayed retention.

It has been suggested that phonological representations play a central role in verbal short-term memory, but when semantic knowledge has been investigated, it has also been shown to influence verbal short-term memory. Explaining this interaction between verbal short-term memory and the linguistic system has produced different theoretical positions: whether semantic knowledge is used to redintegrate phonological traces or if there is direct activation of both phonological and semantic knowledge upon encountering a word. The present study employed a new paradigm to systematically examine phonological and semantic representations in verbal short-term memory as well as long-term impacts. Across two experiments, a list of words was presented sequentially, followed by a probe word. Participants were to judge whether the probe word rhymed or was synonymous with any items on the list. Delayed memory was also tested. In Experiment 1, we found that immediate performance was better for synonym than rhyme judgements, and this continued to be the case after a brief delay. In Experiment 2, under a fast-encoding, running-span paradigm, we found similar activation of phonological and semantic knowledge. Nevertheless, accuracy was again higher for items probed with the semantic than rhyme cue in the long term. Results showed that indeed there are short-term semantic effects, in addition to phonological effects. Further, semantic processing can occur in a highly automatic and rapid manner, with strong influence on long-term memory. These findings provide a new perspective on viewing verbal short-term memory as operating more dynamically within the context of a complex linguistic system.

Neurocognitive mechanisms explaining the role of math attitudes in predicting children's improvement in multiplication skill.

Enhancing student's math achievement is a significant educational challenge. Numerous studies have shown that math attitudes can predict improvement in math performance, but no study has yet revealed the underlying neurocognitive mechanisms explaining this effect. To answer this question, 50 children underwent functional magnetic resonance imaging (fMRI) when they were 11 (time 1; T1) and 13 (time 2; T2) years old. Children solved a rhyming judgment and a single-digit multiplication task inside the scanner at T1. The rhyming task was used to independently define a verbal region of interest in the left inferior frontal gyrus (IFG). We focused on this region because of previous evidence showing math attitudes-related effects in the left IFG for children with low math skill (Demir-Lira et al., 2019). Children completed standardized testing of math attitudes at T1 and of multiplication skill both at T1 and T2. We performed a cluster-wise regression analysis to investigate the interaction between math attitudes and improvement in multiplication skill over time while controlling for the main effects of these variables, intelligence, and accuracy on the task. This analysis revealed a significant interaction in the left IFG, which was due to improvers with positive math attitudes showing enhanced activation. Our result suggests that IFG activation, possibly reflecting effort invested in retrieving multiplication facts, is one of the possible neurocognitive mechanism by which children with positive math attitudes improve in multiplication skill. Our finding suggests that teachers and parents can help children do better in math by promoting positive math attitudes.

Disrupted Subcortical-Cortical Connections in a Phonological but Not Semantic Task in Chinese Children With Dyslexia.

Reading disability has been considered as a disconnection syndrome. Recently, an increasing number of studies have emphasized the role of subcortical regions in reading. However, the majority of research on reading disability has focused on the connections amongst brain regions within the classic cortical reading network. Here, we used graph theoretical analysis to investigate whether subcortical regions serve as hubs (regions highly connected with other brain regions) during reading both in Chinese children with reading disability (N = 15, age ranging from 11.03 to 13.08 years) and in age-matched typically developing children (N = 16, age ranging from 11.17 to 12.75 years) using a visual rhyming judgment task and a visual meaning judgment task. We found that the bilateral thalami were the unique hubs for typically developing children across both tasks. Additionally, subcortical regions (right putamen, left pallidum) were also unique hubs for typically developing children but only in the rhyming task. Among these subcortical hub regions, the left pallidum showed reduced connectivity with inferior frontal regions in the rhyming judgment but not semantic task in reading disabled compared with typically developing children. These results suggest that subcortical-cortical disconnection, which may be particularly relevant to the phonological and phonology-related learning process, may be associated with Chinese reading disability.

Assessing the reliability of an online behavioural laterality battery: A pre-registered study

ABSTRACT Studies of cerebral lateralization often involve participants completing a series of perceptual tasks under laboratory conditions. This has constrained the number of participants recruited in such studies. Online testing can allow for much larger sample sizes but limits the amount of experimental control that is feasible. Here we considered whether online testing could give valid and reliable results on four tasks: a rhyme decision visual half-field task, a dichotic listening task, a chimeric faces task, and a finger tapping task. We recruited 392 participants, oversampling left-handers, who completed the battery twice. Three of the tasks showed evidence of both validity and reliability, insofar as they showed hemispheric advantages in the expected direction and test-retest reliability of at least r = .75. The reliability of the rhyme decision task was less satisfactory (r = .62). We also confirmed a prediction that extreme left-handers were more likely to depart from typical lateralization. Lateralization across the two language tasks (dichotic listening and rhyme judgement) was weakly correlated, but unrelated to lateralization on the chimeric faces task. We conclude that three of the tasks, dichotic listening, chimeric faces and finger tapping, show considerable promise for online evaluation of cerebral lateralization.

Effects of Orthographic Forms on Second Language Speech Production and Phonological Awareness, With Consideration of Speaker‐Level Predictors

AbstractOrthographic forms (spellings) can affect pronunciation in a second language (L2); however, it is not known whether the same orthographic form can affect both L2 pronunciation and metalinguistic awareness. To test this, we asked 260 speakers of English—first‐language (L1) English speakers, L1 Italian and L2 English sequential bilinguals, and L1 Italian learners of L2 English—to perform word repetition tasks and rhyme judgment tasks for word pairs containing the same consonant or vowel spelled with a letter or a digraph. L1 Italian speakers established a long–short contrast and used consonant and vowel length contrastively in their L2 English, both in production and in an awareness task. This provides evidence for a direct link between the effects of the same orthographic phenomenon on speech production and on metalinguistic awareness. Results were strengthened by combining experimental and qualitative data in the study of orthographic effects. Finally, the results show that proficiency predicts orthographic effects, and that orthographic effect predictors vary in naturalistic and instructed contexts.
