Task related paralexias in number reading

Abstract

We present a patient, GR, producing verbal paralexias in reading Arabic numerals. The error rate of his paralexias depended on the kind of task, number reading was embedded in. Thus, he made significantly more errors in reading division problems he had to solve afterwards than in reading the same division problems with the solution already given. Despite paralexic reading of the problem, GR's oral production of the solution was mostly correct. This pattern can be added to those found by Girelli & Delazer (1999) and Delazer & Bartha (2001). It will be discussed in the light of current models of number processing.
