“…A right hemispheric specialization similar to adults was reported already in young children, e.g. for the processing of prosodic information (Homae et al, 2006;Wartenburger et al, 2007). An increase in language lateralization to the left hemisphere, however, was observed with increasing age (Holland et al, 2001;Szaflarski et al, 2006).…”

“…The right-hemispheric FO has been shown to be sensitive to suprasegmental, prosodic information in functional imaging studies in adults (Dehaene-Lambertz et al, 2006a;Friederici and Alter, 2004;Meyer et al, 2004). A right hemispheric involvement for prosodic processes was also reported for 4-year-old children (Wartenburger et al, 2007) and for infants (Homae et al, 2006), both by means of near-infrared spectroscopy (NIRS). Moreover, ERP data have demonstrated that in adults prosodic information influences syntactic parsing very fast, that is in a very early phase during speech comprehension (Eckstein and Friederici, 2006) and that the brain's sensitivity to prosodic features is present not only in adults (Pannekamp et al, 2005), but also in infants (Pannekamp et al, 2006).…”

Temporal dynamics of perisylvian activation during language processing in children and adults

2008

The perisylvian region of the human cortex is known to play a major role in language processing. Especially the superior temporal cortex (STC) and the inferior frontal cortex (IFC) have been investigated with respect to their particular involvement in language comprehension. In the present research, the timing of recruitment of these language-related brain areas in both hemispheres was examined as a function of age using functional imaging data of 6-year-old children and adults with a special focus on blood oxygenation level dependent (BOLD) response time courses. The results show that children's activation time courses differ from that of adults. First, children show an overall later peak of BOLD responses. Second, children's IFC responds much later than their STC, while in adults the difference between both regions is less pronounced. Within the STC, both groups show similar regionally U-shaped activation patterns with fastest peaks in voxels at the STC's mid-portion around Heschl's gyrus and longer latencies in anterior and posterior directions, suggesting a coarsely similar information flow in adults and children in the temporal region. Finally, children in contrast to adults, display a temporal primacy of right over left hemispheric activation. The observed overall latency differences between children and adults are in line with the assumption of ongoing maturation in perisylvian brain regions and the connections between them. A functional perspective on BOLD timing argues for a developmental change from higher processing costs in children compared to adults due to slower and less automatic language processes, in particular those located in the IFC. The observed hemispheric differences are discussed in the context of developmental models assuming a high reliance on right-hemisphere-based suprasegmental information processing during language comprehension in childhood.

“…The first is that, like many distributional learning mechanisms (though see Frank, Goldwater & Keller, 2013 Given the obvious prosodic, pragmatic and structural differences between declaratives and questions, this feature of the model might be regarded as somewhat implausible, particularly in view of recent evidence that even very young children can distinguish between declaratives and questions in the input (Seidl, Hollich & Jusczyk, 2003;Homae, Watanabe, Nakano, Asakawa & Taga, 2006;Soderstrom, Ko & Nevzorova, 2011, Geffen & Mintz, 2012Frota, Butler & Vigário, 2014). For example, Geffen and Mintz (2015) show that by 12 months children can distinguish between declaratives and polar interrogatives even in the absence of prosodic cues, and argue that although infants initially use phonological information to distinguish between sentence types, they have already begun to learn generalisations about the corresponding word-order patterns before the onset of multi-word speech.…”

“…Beyond this shortcoming fNIRS combines a number of features extremely attractive for language research. Being compatible with a natural environment and silent, the method's advantage has been proven in a number of previous studies in language research even in earliest infanthood (Fallgatter et al, 1998;Herrmann et al, 2006;Homae et al, 2006;Horovitz and Gore, 2004;Noguchi et al, 2002;Pena et al, 2003;Taga et al, 2003;Wartenburger et al, 2007, Watanabe et al, 1998. Here we challenge the methodology's potential to explore its versatility and reliability to differentiate activation in the three target areas discussed above (SFG/IPG/IFG).…”

The present study examined cortical oxygenation changes during lexical decision on words and pseudowords using functional NearInfrared Spectroscopy (fNIRS). Focal hyperoxygenation as an indicator of functional activation was compared over three target areas over the left hemisphere. A 52-channel Hitachi ETG-4000 was used covering the superior frontal gyrus (SFG), the left inferior parietal gyrus (IPG) and the left inferior frontal gyrus (IFG). To allow for anatomical inference a recently developed probabilistic mapping method was used to determine the most likely anatomic locations of the changes in cortical activation [Tsuzuki, D., Jurcak, V., Singh, A.K., Okamoto, M., Watanabe, E., Dan, I., 2007. Virtual spatial registration of stand-alone fNIRS data to MNI space. NeuroImage 43 (4), 1506-1518.Subjects made lexical decisions on 50 low and 50 high frequency words and 100 pseudowords. With respect to the lexicality effect, words elicited a larger focal hyperoxygenation in comparison to pseudowords in two regions identified as the SFG and left IPG. The SFG activation difference was interpreted to reflect decision-related mechanisms according to the Multiple Read-Out Model [Grainger, J., Jacobs, A.M., 1996. Orthographic processing in visual word recognition: A multiple read-out model. Psychological Review 103, 518-565]. The greater oxygenation response to words in the left IPG suggests that this region connects orthographic, phonological and semantic representations. A decrease of deoxygenated hemoglobin was observed to low frequency in comparison to high frequency words in a region identified as IFG. This region's sensitivity to word frequency suggests its involvement in grapheme-phoneme conversion, or its role during the selection of preactivated semantic candidates.
