With instruction and practice, however, the elderly can recover the required skills and perform as well as the younger person, expect in those few cases in which the memory loss has a physical cause (see Walsh, 1975). In addition, however, even when the old have stored material in memory effectively, they often have trouble retrieving it from memory (Hultsch, 1975).
