“…Further, this result was consistent across frequency. Our finding of right occipital activation for Chinese characters may be compared with the fMRI results of Chee et al [2000], who found bilateral occipital activation in Chinese-English bilinguals, and with Tan et al [2000Tan et al [ , 2001, who found greater right than left activation in occipital cortex. (The bilateral pattern may reflect stronger English among Singapore bilinguals in Chee et al's [2000] study compared with Tan et al's [2000Tan et al's [ , 2001 sample of Chinese students studying in the United States.)…”

Abstract:Chinese bilinguals performed a delayed naming task, reading both Chinese characters and English words, while EEGs were recorded by a 128-channel system. Principle component analysis (PCA) of Event Related Potentials (ERP) from the onset of the stimulus suggested a temporal unfolding of graphic, phonological, and semantic processing that depended on both language and word frequency. At 150 msec, Chinese produced an earlier and higher amplitude shift (N150) than English. At 250 msec, frequency effects were significant for both Chinese and English, but at 450 msec, only the English frequency effect was reliable. Source localization analysis by Low Resolution Electromagnetic Tomography (LORETA) showed bilateral occipital (left BA 17, right BA 18) visual processing of Chinese characters with left occipital only (left BA 17) for English high-frequency words. Low-frequency English words showed activation bilaterally, but with a more diffused and extended temporal pattern. Right prefrontal area (BA 10) was found to be strongly activated in the mid latency (300 -400 msec) period of Chinese character naming, whereas English word naming showed more medial frontal (BA 8, and 10) activation. A post 450-msec visual verification was found to be general for both writing systems. Hum. Brain Mapping 18:167-175, 2003.

“…In fact, precisely, this distinction between semantic and syntactic processing has been suggested (for review of evidence for shared lexical storage system, see French and Jacquet, 2004). If semantic information in L1 and L2 is supported by the same cortical network, but syntactic information is not, this will clearly cause studies conducted at the word level (Klein, 2003;Chee et al, 1999bChee et al, , 2000Chee et al, , 2003 to show greater similarities between L1 and L2 than studies conducted at the sentence or discourse level (Dehaene et al, 1997;Perani et al, 1996Perani et al, , 1998Wartenburger et al, 2003).…”

“…Some researchers have provided evidence for shared cerebral representation of L1 and L2 (Chee et al, 1999b(Chee et al, , 2000(Chee et al, , 2003Illes et al, 1999), while others argue for distinct representations of L1 and L2 (Dehaene et al, 1997;Marian et al, 2003;Perani et al, 1996, 1998, Wartenburger et al, 2003. This discrepancy could arise from three main factors differing between studies: (1) differences in the linguistic dimension under investigation (i.e.…”

“…In fact, those studies that argue for common representation of L1 and L2 are frequently based on visually presented experimental materials (Chee et al, 1999b(Chee et al, , 2000(Chee et al, , 2003, while studies reporting differences have been conducted using auditory language stimuli (Dehaene et al, 1997;Perani et al, 1996Perani et al, , 1998. Much of the work in the visual domain has been done with Chinese -English bilinguals, capitalizing on the very different orthographic systems underlying Chinese and English.…”

Native and non-native reading of sentences: An fMRI experiment

2006

The processing of syntactic and semantic information in written sentences by native (L1) and non-native (L2) speakers was investigated in an fMRI experiment. This was done by means of a violation paradigm, in which participants read sentences containing either a syntactic, a semantic, or no violation. The results of this study were compared to those of a previous fMRI study, in which auditory sentence processing in L1 and L2 was investigated. The results indicate greater activation for L2 speakers as compared to L1 speakers when reading sentences in several language-and motor-related brain regions. The processing of syntactically incorrect sentences elicited no reliably greater activation in language areas in L2 speakers. In L1 speakers, on the other hand, syntactic processing, as compared to semantic processing, was associated with increased activation in left mid to posterior superior temporal gyrus. In response to the processing of semantically incorrect sentences, both L2 and L1 speakers demonstrated increased involvement of left inferior frontal gyrus. The results of this study were compared to a previously conducted fMRI study, which made use of identical sentence stimuli in the auditory modality. Results from the two studies are in general agreement with one another, although some differences in the response of brain areas very proximal to primary perceptual processing areas (i.e. primary auditory and visual cortex) were observed in conjunction with presentation in the different modalities. The combined results provide evidence that L1 and L2 speakers rely on the same cortical network to process language, although with a higher level of activation in some regions for L2 processing. D

“…We also observed significantly reduced activity in left angular gyrus, left middle frontal gyrus, and bilateral orbital frontal cortex, areas that have been suggested to be involved in visual semantics (Gerlach, 2007) but that are outside of what is considered the core visual category-selective perception network. Interestingly these areas have been strongly implicated in the semantics of language (Binder, Desai, Graves, & Conant, 2009;Price, 2012), and there is evidence for a commonality of neural representations of words and pictures (Bright, Moss, & Tyler, 2004;Chee et al, 2000;Gates & Yoon, 2005;Shinkareva, Malave, Mason, Mitchell, & Just, 2011).…”

Predictability of what or where reduces brain activity, but a bottleneck occurs when both are predictable

Detecting regularities in the sensory environment licenses predictions that enable adaptive behaviour. However, it is unclear whether predictions about object category, location, or both dimensions are mediated by overlapping systems, and relatedly, whether constructing predictions about both category and location is associated with processing bottlenecks. To examine this issue, in an fMRI study, we presented participants with image-series in which non-deterministic transition probabilities enabled predictions about either the location of the next image, its semantic category, both dimensions, or neither (the latter forming a "no-regularity" random baseline condition). Speaking to a common system, all three predictable conditions resulted in reduced BOLD activity in four clusters: left rostral anterior cingulate cortex; bilateral putamen, caudate and thalamus; right precentral gyrus, and left visual cortex. Pointing to a processing bottleneck, in some regions, a significant interaction between the two factors was found whereby category-predictable series were associated with lower activity -but only when location regularity was absent. Finally, category regularity decreased activation in areas of the ventral visual stream and semantic areas of lateral temporal cortex, and location regularity decreased activation in a dorsal fronto-parietal cluster, long implicated in the endogenous control of spatial attention. Our findings confirm and expand a role for dACC/dmPFC and striatum in monitoring or responding to uncertainty in the environment and point to a limited capacity bottleneck when multiple predictions are concurrently licensed.
