AGE DIFFERENCES IN CUMULATIVE LEARNING OF MEANINGFUL AND MEANINGLESS MATERIAL

Age differences in cumulative learning were explored using a technique developed by Hebb. In the first experiment Finnish subjects recalled messages of English digits and in two subsequent experiments English subjects recalled messages of Finnish and of English digits. The finding from the first experiment was that young subjects exhibited cumulative learning while old subjects did not but it was concluded on the basis of the two further experiments that both age groups could show cumulative learning under the conditions used. An age difference in immediate memory for meaningful and meaningless material is noted and the possibility of increasing vulnerability with age to different forms of interference is discussed.
