An important study in the memory literature is an old study by Eysenck (1974) in which he compared the recall of older participants under two levels of processing of the material (low and high). He demonstrated that when asked to perform a higher level of processing of a list of words, participants showed better recall at a later time. Another aspect of Eysenck’s study compared Younger and Older participants on their ability to recall material. One way to look at the Eysenck study mentioned is to compare four groups of participants. One group consisted of Younger participants who were presented the words to be recalled in a condition that elicited a Low level of processing. A second group consisted of Younger participants who were given a task requiring the Highest level of processing. The two other groups were Older participants who were given tasks requiring either Low or High levels of processing.
The data follow:
Younger/Low 8 7 4 6 7 6 5 7 9 7
Younger/Hi 21 19 17 15 22 17 22 21 18 21
Older/Low 9 8 7 8 10 4 6 5 7 7
Older/Hi 10 19 14 5 10 11 14 15 11 10
Conduct a one-way analysis of variance on these data and interpret the results.
