Visual Spatial Learning Test: Normative data and further validation.

The Visual Spatial Learning Test (VSLT) is a nonverbal memory test that requires minimal language and motor abilities. Normative data are presented for VSLT measures of learning, delayed memory, and intrusion errors for 455 individuals ages 56-97 years. Our normative sample is an open community sample that was not screened for memory impairment using psychometric procedures. Validity of these normative data was then assessed by application to a group of patients with dementia. Sequential application of cutoff scores for intrusion errors, learning, and delayed memory correctly identified 87.9% of demented and 78.9% of normal subjects
