MODELLING THE READING OF ISOLATED WORDS
Abstract: I will talk about further joint work carried out within the
split-fovea approach to visual word recognition. In this research we have
used connectionist architectures to simulate the processing going on in the
two halves of the brain, based on the fact that the peripheral anatomy of
the visual pathways shows that a fixated word has its two parts initially
contralaterally projected to the two cerebral hemispheres. I will talk about
the principles of such modelling, and in particular the representation of
letter position in words, and then present simulations of novel data from
normal reading experiments. In particular, I will show that some of the
hemispheric differences in semantic processing may be emergent effects due
to the information structure of words in the English lexicon.
