Normative data for a new memory test: the Shum Visual Learning Test.
This study reports normative data and test-retest reliabilities for a visuo-spatial memory test, the Shum Visual Learning Test (SVLT). Participants were 146 Caucasians (70 males and 76 females, age range between 17-83 years). The test was administered to 116 participants once and 30 participants twice (1 month apart). Age (but not gender and education) was found to affect SVLT test performance. The norms, therefore, were presented according to seven age groups (viz., 17-19, 20-29, 30-39, 40-49, 50-59, 60-69, 70+ years). Three indices (learning, retention after interference, and delayed retention) were derived for descriptive and clinical purposes. The test-retest reliabilities for all trials of the SVLT (except Trial 6) were found to be significant (rs ranged from .63 to .82). Normative data reported allow neuropsychologists to compare patient performances with those of appropriate controls and are important for fostering clinical application of this test.
