Abstract
Semantic and phonological processing (SP and PP, respectively) are described within the dorsal and ventral stream model. Studies have related both types of processing to specific brain areas; however, neuroimaging findings suggest that no exclusive brain areas exist for SP and PP. Overt and covert task paradigms in fMRI have been proposed to examine language processing. However, cognitive processing differs in both paradigms, generating different patterns of neural activity. Covert paradigms do not change language lateralization and provide essential information for understanding language networks. Bilateral activation in frontal areas for SP and PP has been reported as a response to lower task performance in older adults. However, understanding the activation pattern for SP and PP in healthy adults and older adults is still challenging. Therefore, this study aims to determine phonological and semantic auditory processing using a receptive modality task in healthy adults and older people.
