Environmental influences on lexical processing

Access to the lexicon seems to be rather different through the left hemisphere (LH) than through the right hemisphere (RH) of the brain. In this talk I will discuss a unifying principle that accounts for hemispheric asymmetries in orthographic, phonological, and semantic processing. Like most unifying principles it is probably a gross oversimplification, but unlike most unifying principles, it has been tested in implemented models of language processing. I report connectionist models of lexical processing that indicate the interaction between the language environment and the two hemispheres of the brain.
