This paper comments on the article by Plaut and Booth. Plaut and Booth's first simulation shows that there is essentially perfect discrimination between word and nonwords sharing the same orthographic structure when the simulation is carried out in the way we suggested. We take the view that Plaut and Booth's new simulation work settles little beyond the fact that their model can discriminate between words and nonwords with the same orthographic structure. The idea that stages of processing underlie mental computation has a long history and has proven to be a useful theoretical framework for perception, cognition, action, and cognitive neuroscience. We see nothing here that persuades us it should be abandoned.
