Age Differences in a Website Search Task: Older vs.Younger Adults' Navigation and Memory Outcomes

To add a paper, Login.

This study investigated age differences in performance and memory during a website search task. Older adults (53-82 years old) were compared to younger adults (1st year university students). Two navigation tools were used; a hierarchical list and a hierarchical map. Participants completed a 10-question information search. Data on speed, search accuracy and number of pages accessed and revisited was collected during the task. Measures of recall and recognition of the website material were taken immediately after the search task. The results showed that younger adults outperformed older adults on all measures except the recognition scores, which were comparable across the two groups. In addition, older adults revisited more pages than younger adults. The two navigation tools had different effects on the memory outcomes. Both older and younger adults who were given a hierarchical list rather than a hierarchical map had lower scores on recall and recognition of the website material. Also, older adults given the hierarchical list had more page transitions than those given the hierarchical map suggesting a different strategy was chosen to compensate for the lack of support from the navigation tool. A discussion on the implications for continuing education for older adults versus postsecondary education for younger adults is included.
