Subjective ordering, working memory, and aging.
Cognitive decline in aging was studied by presenting four tasks involving short-term memory to young and old adults: digit span forward, missing scan, randomization span, and randomization span visual. Results showed that performance declined significantly with age in the latter two tasks, which require subjective ordering of a sequence of responses, and not in the first two tasks, which involve reproduction of a presented sequence and searching and comparison processes.
