Two different aspects of learning (spatial and nonspatial) and two different types of memory (reference and working) were simultaneously measured in populations of 3- (young), 11- (adult), and 25-month-old (aged) rats fed ad libitum either a standard (ST) or a hypocaloric (HY) diet. All groups, regardless of age or diet, showed ability in learning all four versions of the task. However, old ST rats were significantly slower and less efficient at learning than the young and adult ST rats. In contrast, senescent HY rats' cognitive abilities did not differ from those of their young and adult counterparts. The decline in reference and working memory in the aged ST rats was more pronounced in the spatial than the nonspatial version of the task. This study confirms and extends to more specific aspects of memory our earlier finding that age-related cognitive deterioration in rats was antagonized by life-long calorie restriction.
