Neurophysiology of verb accidence: researches on brain mapping

For many years, acquisition of verbal morphology has been an issue of much debate within linguistic theory, research on first and second language acquisition and neurophysiology of language. In the present review we will consider a set of researches of inflectional morphology in different languages within two main approaches. The proponents of the Dual Mechanism account claim that regularly inflected forms are computed by a rule-processing system, while morphologically irregular forms are processed in associative memory. The opposite Single Mechanism account claims that both regular and irregular forms are processed in associative memory.
