* Title: What can Visual Word Recognition Tell us about Visual Object Recognition?
* Abstract: The SERIOL model addresses the problem of how the brain encodes the
sequence of letters in a written word. It provides a neurobiologically
plausible account of how the initial retinotopic representation of a string
is progressively converted into an abstract, location-invariant encoding
of letter order, and  has led to new accounts of visual half-field
asymmetries in lexical decision, which have been experimentally confirmed.
In the model, location-invariance is achieved by mapping space into
time. That is, the retinotopic encoding is converted into a temporal encoding.
Relative timing of firing of letter pairs is then used to activate bigram
representations. If indeed the brain uses such mechanisms in visual word
recognition, they would have to be derived from the mechanisms normally used
in visual object recognition. I will discuss how this approach could be
extended to object recognition in general, and touch upon some data from
the literature that are consistent with this proposal.
