PS267 Lecture Notes - Lecture 16: Brain Damage, Phoneme, Iconic Memory
Document Summary
Lecture 16 language part 2: the anatomy of language, brain damage and language deficits, the fundamentals of language in the brain, language comprehension, neural models of language comprehension, neural models of speech production, evolution of language. Language comprehension: perceptual analyses of the linguistic input: With spoken words, acoustic input translated into a phonological code. With written words, visual input is translated into an orthographic code. Lexical representations are accessed, selected, and grammatical specifications are considered. A schematic representation of spoken and written language comprehension: bottom-up (perception to concept, top-down processing does influence word recognition talk about later, spoken input: understanding speech. Neural substrates of spoken-word processing: speech first processed in heschl"s gyri, which contain the primary auditory cortex. Activated by speech and non-speech sounds: areas around heschl"s gyri extend into the superior temporal sulcus = auditory association cortex. Both hems do process phonological info (language comprehension) Phoneme processing is localized in the left mid-stg.
