Abstract
Abstract Morphological awareness, the ability to manipulate the smallest units of meaning, is critical for Chinese literacy. This is because Chinese characters typically reflect the morphemic, or morpho-syllabic units of language. Yet, the neurocognitive mechanisms underlying Chinese speakers’ morphological processing remain understudied. Proficient readers (N = 14) completed morphological and phonological judgment tasks in Chinese, in both auditory and visual modalities, during fMRI imaging. Key to our inquiry were patterns of activation in left temporal regions, especially the superior temporal gyrus, which is critical for phonological processing and reading success. The findings revealed that morphological tasks elicited robust activation in superior and middle temporal regions commonly associated with automated phonological and lexico-semantic analyses. In contrast, the rhyme judgment task elicited greater activation in left frontal lobe regions, reflecting the analytical complexity of sound-to-print mapping in Chinese. The findings suggest that left temporal regions are sensitive to salient morpho-syllabic characteristics of a given language.

There is considerable behavioral evidence that morphologically complex words such as ‘tax-able’ and ‘kiss-es’ are processed and represented combinatorially. In other words, they are decomposed into their constituents ‘tax’ and ‘-able’ during comprehension (reading or listening), and producing them might also involve on-the-spot combination of these constituents (especially for inflections). However, despite increasing amount of neurocognitive research, the neural mechanisms underlying these proc...

ABSTRACTThe developmental process of reading acquisition is frequently conceptualized as a self-organizing mental network consisting of lexico-semantic, phonological and orthographical components. The developmental nature of this network varies across languages and is known to impact second-language learners of typologically different languages. Yet, it remains largely unknown whether such cross-linguistic differences interact within young bilingual learners of two typologically different langua...

In the present study, we examined the role of morphological awareness in reading and spelling performance across three languages varying in orthographic consistency (English, French, and Greek), after controlling for the effects of phonological awareness and rapid automatized naming (RAN). One hundred fifty-nine English-speaking Canadian, 238 French-speaking Canadian, and 224 Greek children were assessed at the beginning of Grade 2 on measures of morphological awareness, phonological awareness, ...

Children from low-SES families are known to show delays in aspects of language development which underpin reading acquisition such as vocabulary and listening comprehension. Few studies have focused on the development of morphological skills in this group, and none in French. The present study investigated the involvement of morphological knowledge in the very early stages of reading acquisition (decoding), before reading comprehension can be reliably assessed. We assessed listening comprehensio...

Can bilingual exposure impact children's neural circuitry for learning to read? To answer this question, we investigated the brain bases of morphological awareness, one of the key spoken language abilities for learning to read in English and Chinese. Bilingual Chinese-English and monolingual English children (N = 22, ages 7–12) completed morphological tasks that best characterize each of their languages: compound morphology in Chinese (e.g. basket + ball = basketball) and derivational morphology...

Differences in how writing systems represent language raise important questions about the extent to which the role of linguistic skills such as phonological awareness (PA) and morphological awareness (MA) in reading is universal. In this meta-analysis, the authors examined the relationship between PA, MA, and reading (accuracy, fluency, and comprehension) in 2 languages (English and Chinese) representing different writing systems (alphabetic and logographic). A random-effects model analysis of d...

Recently, Eklund et al. (1) analyzed clustering methods in standard fMRI packages: AFNI (which we maintain), FSL, and SPM. They claim that ( i ) false-positive rates (FPRs) in traditional approaches are greatly inflated, questioning the validity of “countless published fMRI studies”; ( ii ) nonparametric methods produce valid, but slightly conservative, FPRs; ( iii ) a common flawed assumption is that the spatial autocorrelation function (ACF) of fMRI noise is Gaussian-shaped; and ( iv ) a 15-y-...

The correspondence in meaning extracted from written versus spoken input remains to be fully understood neurobiologically. Here, in a total of 38 subjects, the functional anatomy of cross-modal semantic similarity for concrete words was determined based on a dual criterion: First, a voxelwise univariate analysis had to show significant activation during a semantic task (property verification) performed with written and spoken concrete words compared to the perceptually matched control condition....

The spatiotemporal dynamics of morphological, orthographic, and semantic processing were investigated in a primed lexical decision task in French using magnetoencephalography MEG. The goal was to investigate orthographic and semantic contributions to morphological priming and compare these effects with pure orthographic and semantic priming. The time course of these effects was analyzed in anatomically defined ROIs that were selected according to previous MEG and fMRI findings. The results showe...

Morphological decomposition is an important part of complex word processing and the left inferior frontal gyrus (L-IFG) has been shown to be a key brain area involved in morphological processing in alphabetic languages. Chinese morphological processing requires a comprehensive consideration of phonological, orthographic and morphemic information. But it had been unclear whether the neural mechanisms underlying morphological processing in alphabetic languages would also be found for Chinese. To a...
