For example, it has been suggested that language deficits in expressive aphasia may be caused by excessive competition between lexical units, thus preventing any word from becoming sufficiently activated. [9] Arguments for this hypothesis consider that mental dysfunction can be explained by slight perturbation of the network model's processing.
This two-staged model is the most widely supported theory of speech production in psycholinguistics, [2] although it has been challenged. [3] For example, there is some evidence to indicate that the grammatical gender of a noun is retrieved from the word's phonological form (the lexeme) rather than from the lemma. [ 4 ]
Psycholinguistics or psychology of language is the study of the interrelation between linguistic factors and psychological aspects. [1] The discipline is mainly concerned with the mechanisms by which language is processed and represented in the mind and brain; that is, the psychological and neurobiological factors that enable humans to acquire, use, comprehend, and produce language.
Neurolinguistics is closely related to the field of psycholinguistics, which seeks to elucidate the cognitive mechanisms of language by employing the traditional techniques of experimental psychology. Today, psycholinguistic and neurolinguistic theories often inform one another, and there is much collaboration between the two fields. [13] [15]
The cohort model in psycholinguistics and neurolinguistics is a model of lexical retrieval first proposed by William Marslen-Wilson and Alan Welsh in the late 1970s. [1] It attempts to describe how visual or auditory input (i.e., hearing or reading a word) is mapped onto a word in a hearer's lexicon . [ 2 ]
The Competition Model is a psycholinguistic theory of language acquisition and sentence processing, developed by Elizabeth Bates and Brian MacWhinney (1982). [1] The claim in MacWhinney, Bates, and Kliegl (1984) [2] is that "the forms of natural languages are created, governed, constrained, acquired, and used in the service of communicative functions."
The methods of neuro-linguistic programming are the specific techniques used to perform and teach neuro-linguistic programming, [1] [2] which teaches that people are only able to directly perceive a small part of the world using their conscious awareness, and that this view of the world is filtered by experience, beliefs, values, assumptions, and biological sensory systems.
Freud was skeptical of Wernicke's findings, citing a paucity of clinical observation as his reason. Although he conceded the fact that language is linked to neurological processes, Freud repudiated a model of localization of brain function, according to which specific regions of the brain are responsible for certain cognitive functions.
