Here's the Abstract:

Abstract

In this paper we describe a computational model of visual word 
recognition and reading aloud, the Dual Route Cascaded (DRC) model, a 
computational realisation of the dual-route theory of reading. The 
two tasks most commonly used to study reading are lexical decision 
and reading aloud; the DRC model is the only computational model of 
reading which can perform both of these tasks. The model is evaluated 
by comparing its lexical decision latency data to lexical decision 
latency data from various published studies of human subjects, and by 
comparing its reading aloud latency data to reading aloud latency 
data from various published studies of reading aloud by human 
subjects. For both tasks, it is found that a wide variety of 
variables which affect human latencies affect the DRC model's 
latencies in exactly the same way. We note a number of such effects 
which the DRC model simulates but which other computational models of 
reading do not, whereas as far as we are aware there are no effects 
which any other current computational model of reading can simulate 
but which the DRC model cannot. We conclude that the DRC model is the 
most successful of existing computational models of reading.

M.C.
