AbstractThis paper reports an investigation of the impaired writing of an acquired dysgraphic patient J.E.C. who made several case, substitution, omission, and addition errors when writing lower-case letters cursively, but whose upper-case writing was intact. The main finding was that damage to the lower-case letter production system results in errors that can be predicted from the spatial similarity of the lower-case form of the error to the lower-case form of the target. This was found with both within-case and cross-case letter substitutions. An additional observation was consistent cross-case errors occurred only with targets forming a single cluster of spatially similar lower-case letters (b, d, p, and q). It is concluded access to lower-case letters is constrained by spatial similarity of a target to other letters in allograph store, and this effect may explain letter errors made by dysgraphic patients.
