Abstract

The relationship between unilateral visual neglect and production of narrative discourse in bye patients with right hemisphere damage (RHD) was examined longitudinally. Initially, all subjects demonstrated a left unilateral neglect on the Behavioural Inattention Test (Wilson et al. 1987a). During subsequent testing at 6-8 months and 12-16 months post-onset, subjects with a persistent unilateral neglect produced less concise discourse with reductions in the percentage of meaningful content units as compared to a group of control subjects. Subjects with a transient unilateral neglect produced informational content that was comparable to the normal subjects. Results support the notion that the presence and persistence of a unilateral visual neglect might assist in delineating more homogeneous groups of RHD subjects.
