ABSTRACT fMRI was used to investigate brain organization for reading in Chinese. Subjects were shown two-character Chinese words. A control task was used to eliminate the non-linguistic visual and motor confounds. Results show that naming of Chinese logographs is characterized by left-lateralized neuronal networks for the processing of orthographic, phonological, and semantic attributes. The orchestration of the middle frontal cortex, superior temporal cortex, superior parietal cortex, basal temporal area and extrastriate cortices of the left hemisphere may manifest the particularity of the central representation of simple word naming in Chinese.

    ABSTRACT: The current study used functional MRI (fMRI) to obtain a comprehensive understanding of the neural network underlying visual word recognition in Hindi/Devanagari, an alphasyllabic - partly alphabetic and partly syllabic Indian writing system on which little research has hitherto been carried out.

    ABSTRACT: Although the functional brain network involved in reading for adults and children is now well documented, a critical lack of knowledge still exists about the structural development of these brain areas. To provide a better overview of the structural dynamics of the brain that sustain reading acquisition, we acquired anatomical MRI brain images from 55 children that were divided into two groups: one prior to the formal learning of reading (n = 33, 5-6 years old) and the second a few years after formal learning (n = 22, 9-10 years old). Reading performances were collected based on the "Alouette-R" test, a standardized test for reading text in French. Voxel-based morphometry analysis of gray matter showed that only the right insula volume was different between the two groups. Moreover, the reading group showed that the volumes of the left fusiform gyrus (corresponding to the well-known visual word form area, VWFA), the anterior part of the left inferior occipital gyrus and the left thalamus were significantly modulated by reading performance. This study reinforces the crucial role of the Visual Word Form Area in reading and correlation analyses performed between ROIs volumes suggesting that the VWFA is fully connected with the traditional left-hemispheric language brain network.

    ABSTRACT: A long-running debate in Chinese psycholinguistics has concerned the relative roles of semantics and phonology in reading Chinese characters. Some researchers argue that character reading requires activation of phonological representations, while others maintain the traditional view that Chinese readers generally access meanings directly without phonological mediation. This paper describes an experiment that addresses this debate from a novel direction: Chinese readers were asked to report what they know about simple characters with unfamiliar meanings and/or pronunciations. The "phonology-first" view predicts that it should be impossible to know the meaning of a character without knowing its pronunciation, while the "semantics-first" view predicts that it should be impossible to know the pronunciation of a character without knowing its meaning. Our experiment showed that both situations can exist, though with quantitative and qualitative differences: knowing the pronunciation without knowing the meaning is a somewhat more common occurrence, though it arises most often with characters that share a phonological component with other characters, while knowing the meaning without the pronunciation most often occurs when readers have an alternative (nonstandard) pronunciation for the character or when the character is used as a quasi-linguistic symbol. Moreover, a signal detection analysis found no difference in sensitivity to meaning vs. pronunciation. At the same time, however, readers were strongly biased in their
