Document Summary
Lecture 11 - the universe of language - loss of language. Language is an extremely complex cognitive world, with several distinguishable components: The articulation and perception of identifiable different linguistic sounds. The abstract representation of different categories of linguistic sound-units, such as phonemes, syllables, and morphemes. The inter-dependence of adjacent linguistic units when they combine into words and idioms. The meaningful minimal units of language, mostly words, but also morphemes and idioms. The principles governing the combination of words into sentences. The study of the context-independent effect of linguistic forms on linguistic meanings. The rules of appropriate use of linguistic expressions in difference situations. One or more of the above components can be selectively impaired. This phenomenon is known as traumatic aphasia = loss of speech. There are strict correlations between the affected brain region and the language deficit that corresponds to that lesion. The issue of modularity is very relevant in these cases.
