Note: Values in italics denote abnormal performance represented by scores falling beyond two standard deviations below performance of a group of between 100 and 24 (depending on the test) control participants comparable in terms of age and education; for Digit Span, abnormal scores are two standard deviations below age-appropriate means (Ivnik et al., 1992); for the Raven's, abnormal performance is that below the 50th percentile for older controls in norms. NT = not tested; MMSE = Mini-Mental State Examination; VOSP = Visual Object and Space Perception battery (Warrington & James, 1991); PALPA = Psycholinguistic Assessment of Language Processing in Aphasia (Kay et al., 1992b).
