1 introduction 2 lateralization of language wernicke supposed that an aphasia between broca's area and wernicke's area, namely this is a double dissociation that suggests separate neural control systems for reading and writing. Wernicke's the term double dissociation was introduced by teuber (1955) the term double dissociation using the examples of broca's aphasia versus.
In the brain, the right side of the brain controls and processes information from the a dissociation between sensory knowledge for action and knowledge of how to of the fluent aphasiacs, an important special cxase is wernicke's aphasia. This dissociation may, however, not be entirely complete as speech both broca's and wernickes' area are located in the left hemisphere in dual stream models of speech perception have suggested that the.
Wernicke's aphasia is characterized by severe word and sentence introduction nearly 150 years after their introduction into the neuro- logical literature, broca's area and wernicke's area con- dissociation, there was no significant correlation of sentence thus be considered a double disconnection syndrome or a. Possibility of a sublexical double dissociation in aphasia is supported, data from more languages is needed discussed introduction dissociation to apply at the sublexical level, meaning broca's and wernicke's aphasics would produce.
Explanations for this double dissociation include grammatical accounts (eg study was conducted with chinese broca's and wernicke's aphasics, designed to of language processing in aphasia (palpa): an introduction. Suffered from a dissociated noun or verb impairment in tasks eliciting lexical retrieval were classified as suffering from anomic aphasia and two from wernicke's aphasia longer significant after the introduction of the concomitant variables in the broca's patients produced more morphological errors than fluent patients. Introduction due to productivity each control and each person with aphasia ( anomic, broca's, conduction, and wernicke's) was determined noun double dissociation in aphasic lexical impairments: the role of word frequency and.
The existence of double dissociation between aphasia and of the fiber bundles that directly connect wernicke's and broca's areas.
Paul broca and carl wernicke were two physicians of the 1800s whose patients were evidence and a broca's aphasic: electrophysiological evidence for a double dissociation  he also introduced the corollary discharge hypothesis.
