Note: Values in italics denote abnormal performance represented by scores falling beyond two standard deviations below control performance where normative data available; for Digit Span, abnormal scores are two standard deviations below age-appropriate means (Ivnik et al., 1992). VOSP = Visual Object and Space Perception Battery (Warrington & James, 1991); PALPA = Psycholinguistic Assessments of Language Processing in Aphasia (Kay, Lesser, & Coltheart, 1992a); MCA = middle cerebral artery; PCA = posterior cerebral artery; RT = reaction time; NT = not tested; NA = not available.
