This study reports Auditory Verbal Learning Test (AVLT) data for 153 adults in age groups spanning seven decades, with approximately equal numbers of males and females and matched for intelligence, education, and occupation. Overall performance deteriorated with increased age, females performing better than males. Older subjects recalled fewer words, were more susceptible to information overload during input, showed diminished retrieval efficiency, and had a decline in memory for the source of items. In contrast, rate of learning, forgetting over 20-min, monitoring of recall, and interference effects remained stable across the age range.
