We describe preliminary data from two studies aimed at investigating the psychometric properties and validity of newly developed measures of morphological knowledge and skills in Russian, namely, the Word Structure subtest, and the Test of Morphological Awareness, in two samples of young Russian-speaking children. Overall, both instruments demonstrated good psychometric properties when analyzed using both classical test theory and a Rasch-modeling IRT approach, and were positively associated with the criterion measures i.

Language acquisition is the process by which humans acquire the capacity to perceive and comprehend language in other words, gain the ability to be aware of language and to understand it , as well as to produce and use words and sentences to communicate. Language acquisition involves structures, rules and representation. The capacity to use language successfully requires one to acquire a range of tools including phonology , morphology , syntax , semantics , and an extensive vocabulary.

History of Neuroscience View all 9 Articles. For British neurologists, one case was considered to represent significant evidence regarding the organization of language in the brain in the second half of the 19th century. The interpretation of its significance was based on repeated standard clinical assessment of behavioral deficits, the use of a psychological model of processing, and lesion localization to inform understanding of clinic-pathological correlation. The aphasic deficits experienced by a single case were observed and recorded by London neurologist Henry Charlton Bastian — over a period of 18 years and used as a demonstration of clinico-pathological reasoning regarding language function. When this patient died, the autopsy findings were added to the extensive record of his language deficits. This single case was a significant source of discussion and reflection in the medical community throughout the second half of the 19th century.

Two modern English language neurological and neuropsychological reference books were searched to identify 17 such terms in contemporary usage: amnesia, akinesia, ataxia, aphasia, agraphia, anosmia, apraxia, athetosis, ageusia, achromatopsia, agnosia, alexia, amusia, anomia, anarthria, anosognosia, and acalculia. These were traced to their initial association with acquired neurocognitive impairment in German, English, and French language medical publications from the late 18th, 19th, and early 20th centuries through Some of these terms e. The remainder constitute novel semantically plausible e. This is a preview of subscription content, access via your institution. Rent this article via DeepDyve.

Speech Pathology and Audiology (SPA)

Classic models of language organization posited that separate motor and sensory language foci existed in the inferior frontal gyrus Broca's area and superior temporal gyrus Wernicke's area , respectively, and that connections between these sites arcuate fasciculus allowed for auditory-motor interaction. These theories have predominated for more than a century, but advances in neuroimaging and stimulation mapping have provided a more detailed description of the functional neuroanatomy of language. New insights have shaped modern network-based models of speech processing composed of parallel and interconnected streams involving both cortical and subcortical areas. Phonological processing occurs along a dorsal pathway, from the posterosuperior temporal to the inferior frontal cortices. On the other hand, semantic information is carried in a ventral pathway that runs from the temporal pole to the basal occipitotemporal cortex, with anterior connections.

Communication in humans activates almost every part of the brain. Of course, the use of language predominates, but other cognitive functions such as attention, memory, emotion, and executive processes are also involved. Broca and Wernicke and Lichtheim and many others , during the 19th century, when brain research was mainly observational and autopsy driven, offered fundamental knowledge about the brain and language, so the Wernicke-Geschwind model appeared and aphasiology during the 20th century was based on it.

Studies of language disorders have shaped our understanding of brain—language relationships over the last two centuries. This article provides a review of this research and how our thinking has changed over the years regarding how the brain processes language. One hundred years later, the emergence of new brain imaging tools allowed for the visualization of brain injuries in vivo that ushered in a new era of brain-behavior research and greatly expanded our understanding of the neural processes of language. Toward the end of the 20th century, sophisticated neuroimaging approaches allowed for the visualization of both structural and functional brain activity associated with language processing in both healthy individuals and in those with language disturbance. More recently, language is thought to be mediated by a much broader expanse of neural networks that covers a large number of cortical and subcortical regions and their interconnecting fiber pathways.
