The Verbal Learning Test (VLT; Rey, 1958)
evaluates the declarative memory. Despite its extensive use, it has been
difficult to establish normative data because test administration has not
been uniform. The purpose of the present study was to gather normative
data for the VLT for a large number (N = 1855) of healthy
participants aged 24–81 years, using a procedure in which the words
to be learned were presented either verbally or visually. The results
showed that VLT performance decreased in an age-dependent manner from an
early age. The learning capacity of younger versus older adults
differed quantitatively rather than qualitatively. Females and higher
educated participants outperformed males and lower educated participants
over the entire age range tested. Presentation mode affected VLT
performance differently: auditory presentation resulted in a better recall
on Trial 1 (a short-term or working memory measure), whereas visual
presentation yielded a better performance on Trial 3, Trial 4, and Delta
(a learning measure). (JINS, 2005, 11,
