PSYB65H3 Lecture Notes - Lecture 10: Receptive Aphasia, Expressive Aphasia, Temporal Lobe
Document Summary
Brain organization in terms of laterality: right and left hemisphere, language. Language in greater depth: how language is organized in left hemisphere. Right handed individuals: language on left hemisphere. Left handed and ambidextrous individuals: language is bilaterally represented. Experimental data from language in the past was mostly obtained from people with: strokes, automobile accidents, gunshot wounds, etc. Today, pet scans / fmri / etc make it easier to study language in the brain. Aphasias: dysphasia is more appropriate term, but no one uses it, literally meaning: no language. Mostly mild only some degree of language loss. The bigger the stroke the bigger the lesion the more severe the symptoms will be. Receptive aphasia: receiving information about language, getting language in understanding language, decoding language. Integrative aphasia: problems in the comprehension of language, problems in the formation of language. Expressive aphasia: getting language out expression of language.
