Abstract: In this work the short-term memory of 102 subjects 50-90 years of agewas studied, in 85 ones of whom physical health-conditions were thoroughly.examined. A contol group of 22 people of 22-25 years old also took thememory-tests. The results were as follows: 1) The efficiency of memory decreases with the increase of age in thefree recall of pictures, the reproduction of logical stories, and the digit-span. 2) In the reproduction of logical stories, the memory of the central ideaof stories degenerates slower than that of the pieces of stories. Thedegeneration in performance of digit-foreward is slower than that in all othermemory functions save the memory of central idea of stories. These suggestthe characteristic of memory degeneration of aging. 3) The pathological or aging changes in nervous system and cardio-vascular system are related to the deterioration in memory.
