Agnosia
Dear All, Does anyone know who introduced the term 'agnosia' to refer either to (a) aphasia-like conditions in which there was some disturbance of object recognition or (b) conditions like Munk's Seelenblindheit? I'd always thought that meaning (a) came from Freud's 1891 'Aphasie' where he defines the 'agnostic aphasias' as a third kind of aphasia in addition to the 'language' aphasias described by Broca and Wernicke, as one often involving vision. However, Marrianne Jackson uses 'visual agnosia' in translating the title of Lissauer's 1890 paper. That, however, may be only a modern convenience, so to speak, because the word in Lissauer's title is Seelenblindheit. As I don't have the original German I don't know if he uses 'agnosia' in his text.
