Factorial Validation of the Ruff-Light Trail Learning Test (RULIT)

The factorial validity of the Ruff-Light Trail Learning Test (RULIT) was evaluated for its specificity as a test of visuospatial learning and memory. In a sample of 307 normal adults, principal components analyses (PCAs) were calculated on scores from the RULIT and selected neuropsychological tests. The PCAs revealed visuospatial learning and memory components, which included RULIT scores that were empirically distinct from verbal learning and memory components. These results provide support for the RULIT as a measure of visuospatial learning and memory.

Key Words: RULIT • visuospatial learning • visuospatial memory • principal components analysis • normal population
