- Mental lexicon: is it real? where is it located?
- neurobiology of words:
- a word has a phonological form and meaning
- all words are stored in a mental lexicon/dictionary
- what are the neural substrates implicated in word processing and the lexicon as shown through brain
damage (category specific)
- we look at different aphasias etc to locate category-specific deficits
- Boston naming test: show people an object; they should be able to name it and say what it's used for
- Geschwind thinks that the lexicon is close to Wernicke`s area
- lesions to fusiforméoccipital gyrus causes deficit in naming living things
- temporal = naming objects and inanimate objects
- frontal = verb naming
- you have to look at the type of error as well as if there is an error or not
- how do we explain category-specific deficits?
- there are two groups of theories: one that is modular, and one that is
- neural-structure principles: the domain-specific account.
- come up with groups: tools, animals, fruits and vegetables. (why do we come up with these
distinctions? they're actually based on functionally distinct neural circuts. these things had to be
identified quicker for reproduction or survival)
- modular theories can not explain some thi
