This paper describes the author's implementation of a parser aimed at reproducing, in a computationally explicit system, the constraints of a particular psycholinguistic model (Gorrell in press). In Gorrell's model, "unconscious" garden paths may be processed via the addition of structural relations to a monotone increasing set at the point of disambiguation, but there is no discussion as to how the parser decides which relations to add. We model this decision as a search for a node in the tree at which an explicitly defined parsing operation, tree-lowering may be applied. With reference to English and Japanese processing data, we show the importance of this search for empirical adequacy of the psycholinguistic model.
