LIN 201 Lecture Notes - Brain Damage, Morpheme, Corpus Callosum
Document Summary
Claim: content & func. words are represented diff. in brain. Damage to diff. parts of brain change lang. in diff. ways. Func. words never switched (is throat my sore) Lexicon = sound+meaning for all content words & content morph. Things we say are built of sm. units arranged in hierarchy. Mind = abstract things that happen inside brain (software) Brain is split in 2 hemis. connected by corpus callosum. Funcs. are lateralized to one hemi. or the other. Contralaterality: l hemi. controls r side of body (& vice versa) Aphasia = brain damage resulting in ling. deficit. When l hemi. removed, lang. impairment or loss. Hearing one thing in one ear and a diff. thing in the other ear. Word heard in r ear is heard better. Non-ling. sound (haha, cough) heard in l ear is heard better. Broca"s aphasia: impaired syntax, mostly content words, pauses. Wernicke"s aphasia: nothing makes sense, but said fluently.
