Resumen
The Rey Auditory Verbal Learning Test (RAVLT) is a useful tool for clinical evaluation
of memory loss processes. This study aims to evaluate the e ffects of cognitive training and
sleep hygiene techniques on word memorization in a RAVLT test applied to 60-86 year old
subjects. The individuals in the study were randomly allocated to four treatments of
interest: control, cognitive training, sleep hygiene and a combination of cognitive training
with sleep hygiene. Data on the post-treatment number of recalled words and related
memorization indexes are analyzed by covariance analyses, taking the corresponding preintervention
measures as covariates values. The results suggest that cognitive training
combined with sleep hygiene may increase the average number of words recalled in the
spontaneous evocation phase of the test in relation to the control group. Covariance
analysis is seen to be generally more e cient than analysis of variance to compare the
treatment e ffects.
