“…English as the first foreign language was also observed in bilingual Japanese participants (Yokoyama et al 2006). As the cerebellum plays an important role in articulation-related motor processes (Ackermann et al 1998;Silveri and Misciagna 2000), increased activity may reflect the larger demands on motor planning in a language at a low proficiency level.…”

“…In word generation, activity in left IFG decreased with increasing proficiency of L2 (Yetkin et al 1996). Increased activity in left IFG during L2 processing was also obtained for sentence comprehension (Yokoyama et al 2006), or processing of syntactic structure (Suh et al 2007). As the left IFG is involved in several language tasks including phonetic, syntactic and semantic processing (Indefrey and Levelt 2000), its specific importance for processing a less fluently spoken L2 has not been unequivocally determined yet.…”

Speaking in multiple languages: Neural correlates of language proficiency in multilingual word production

et al. 2010

The human brain has the fascinating ability to represent and to process several languages. Although the first and further languages activate partially different brain networks, the linguistic factors underlying these differences in language processing have to be further specified. We investigated the neural correlates of language proficiency in a homogeneous sample of multilingual native Ladin speakers from a mountain valley in South Tyrol, Italy, who speak Italian as second language at a high level, and English at an intermediate level. In a constrained word production task under functional magnetic resonance imaging (fMRI), participants had to name pictures of objects in Ladin, Italian and English in separate blocks. Overall, multilingual word production activated a common set of brain areas dedicated to known subcomponents of picture naming. In comparison to English, the fluently spoken languages Ladin and Italian were associated with enhanced right prefrontal activity. In addition, the MR signal in right prefrontal cortex correlated with naming accuracy as a measure of language proficiency. Our results demonstrate the significance of right prefrontal areas for language proficiency. Based on the role of these areas for cognitive control, our findings suggest that right prefrontal cortex supports language proficiency by effectively supervising word retrieval.

“…In lesion studies, it has been reported that nouns and verbs are distinctly processed in the human brain (e.g., Bates et al, 1991;Miceli et al, 1988;Shapiro & Caramazza, 2003). In contrast, in neuroimaging studies, while several studies reported that different brain activations exist between noun and verb processing Tyler et al, 2004;Yokoyama et al, 2006b), others find no difference between them Li et al, 2004). Based on the reported findings, several possibilities are proposed at this time.…”

“…While the temporal lobe plays a role in storing long term memory, the role of the left posterior part of superior/middle temporal gyri is still unclear. As evidence, most neuroimaging studies using comparisons between real word and pseudoword comprehension have reported that this region is more active for real word comprehension than for pseudoword comprehension (e.g., Pugh et al, 1996;Price et al, 1997;Friederici et al, 2000;Booth et al, 2002;Fiebach et al, 2002;Yokoyama et al, 2006b, and others). In contrast, Fiebach et al (2002) showed that the left inferior frontal region is modulated by word frequency while the left posterior part of the middle temporal gyrus is not.…”

“…Based on the reported findings, several possibilities are proposed at this time. One possibility is that a cross-linguistic difference influences such discrepancy as the reported neuroimaging studies used different languages as stimuli (Yokoyama et al, 2006b). Still, despite the discrepancy among languages, the reported brain activations were located in the left inferior frontal gyrus and posterior superior/middle temporal gyrus.…”
