Abstract: | Functional magnetic resonance imaging was used to investigate the role of phonology in visual word recognition (VWR). A group
of children between the ages of 7 and 13 participated in a lexical decision task in which lexical frequency and homophony
were manipulated. A significant homophone effect was observed for the high-frequency condition, indicating that phonology
does indeed play a significant role in VWR. The brain activation patterns also support this idea in that regions that have
been linked to phonological processing, the inferior frontal gyrus and the inferior parietal lobe, also revealed a homophone
effect. Additionally, the posterior superior temporal cortex showed a homophone effect; however, this activation is argued
to be related to lexical competition generated by the high-frequency homophone via the activation of multiple semantic representations. |
