520 $a In contrast to our ability to learn many types of information, adults tend to attain a greater degree of mastery of languages learned in childhood than languages learned later in life. This dissertation examines whether differential patterns of neural organization for language may also be found for second languages learned in adulthood. The first two studies were designed to investigate the functional organization of the brain for language processing in native English speakers. In Chapter II, event-related brain potentials (ERPs) were recorded while participants read sentences, which were either well-formed or contained violations of regular or irregular inflectional morphology, syntactic phrase structure, or semantic-pragmatic constraints. Each type of violation was associated with a unique spatial-temporal pattern of brain activity, although some similarities were seen in the later stages of processing phrase structure and inflectional violations. Chapter III employed the experimental paradigm used in Chapter II in a functional magnetic resonance imaging (fMRI) experiment. The processing of phrase structure and semantic violations were associated with the activation of distinct brain regions, demonstrating the applicability of the paradigm to an fMRI setting and supporting the findings from Chapter II of functional neural dissociations in line with predictions from theoretical linguistics. Chapter IV investigated the effect of age of acquisition in determining the neural organization for language, by comparing the effects of native and post-pubertal acquisition of American Sign Language (ASL) on the neural regions involved in its processing. While fMRI demonstrated that native and late-learning hearing participants showed largely similar ASL-related patterns of brain activation, native learners showed additional and unique activation in a region of the right inferior parietal lobe. Together, these studies demonstrate functional specializations in language processing at the neural level which parallel certain predictions made by theoretical linguistics, and suggest that delayed language acquisition has important effects on the brain regions used for linguistic processing.
