Computational linguists that seriously consider both the linguistic and the experimental evidence also come to the conclusion that there is no principled distinction between the structure and realization of morphemes within (phonological) words and the structure and realization of combinations of words and phrases. This textbook provides a comprehensive introduction to the emerging fields of neurolinguistics and linguistic aphasiology. Neurolinguistics, the study of the neurological mechanisms underlying the storage and processing of language. One hundred and forty healthy subjects aged 20 to 65 years (69 men) participated in the experiments. In addition to providing plausible models of normal linguistic functions, these models have provided accounts for linguistic deficits. It has provided sufficient accounts of high-level behaviors using distributed networks of simple processing units. The main features of connectionist networks are multiple, simple processing units computing in parallel. Another perspective on neurolinguistic modeling should also be considered: the similarities between the grammatical deficits of fluent and nonfluent aphasics. In addition, there are specific research questions that are amenable to ERP testing, such as the locus of language representation in aphasics who have recovered some linguistic ability (for example Papanicolaou, DiScenna, Gillespie, & Aram, 1990; Papanicolaou, Moore, Deutsch, Levin, & Eisenberg, 1988), but we will not cover them here. Introduction Linguistics Cupid Lucid. The neurolinguistic approach stresses the role of language in aphasia and analyzes it according to principles of theoretical linguistics. While providing demonstrations of higher-level cognitive capacities, connectionist models have also been used to model aspects of primary motor and sensory systems. Psycholinguistics or psychology of language is the study of the psychological and neurobiological factors that enable humans to acquire, use, and understand language. For Pinker, it was a syntactic fact that an irregular past-tense form like taught was a single computational unit, represented as a nonbranching tree structure, as compared with a regular form like walked, which would consist of a separate stem and past-tense morpheme in hierarchical syntactic structure. Finally, targeting discourse, especially discourse gist through cognitive training, has helped strengthen higher order cognitive functions thereby building brain health fitness. Outstanding questions about the right hemispere's role might prove pertinent also to the practical issues of aphasia remediation (see Code, 1987). For example, although the activation levels are often taken to represent the average firing rate of a small group of real neurons, it may be that the temporal characteristics of neuronal spike trains encode information, which would make a single real activation value insufficient to model real neurons’ representations. Linguistic morphology, then, should be a key element in the neurobiology of language enterprise. The brain is divided into … The wide differences between these characteristics are important because it simply makes it easier to see how the evolution of language and communication changes among the different individuals in society. The networks of the classical language area, and other networks of the brain, may differ in degree only in how amenable they are to the language function. For neurolinguistic theory, left-to-right transfer might engender some skepticism about the uniqueness of human language circuitry and its allegedly modular organization. As Zurif points out (personal communication, 1981), this view would be strengthened if the detailed profiles of grammatical deficits prove to look different when patients with multi-modal agrammatism are compared with those whose agrammatism is restricted to a single modality. Regarding the opposing view of Baayen et al. Nesaab September 13, 2019. Neurolinguistic work of the next decades should uncover how the brain accesses representations of morphemes, combines these representations into hierarchical syntactic structures, and realizes these structures in form and meaning. These would interact, since a damaged representation could give an illegal input to a process, while a damaged process could give rise to an impoverished or illegal representation as output.
