“…The result suggested that if getting to the target page in as few clicks as possible was the main aim of the online information design then it would be better to arrange the information in an expandable hierarchical structure. The findings that there was a difference in speed but not in accuracy between older and younger age groups was in line with findings from previous research (Ellis, Kogan & Rowan, 1999).…”

The present study investigates time and click error differences when older and younger computer users traversed expandable and non-expandable online hierarchical information structures to reach a target. The results show that older users were slower but did not make more errors than their younger counterparts, suggesting more cautious decision making. The study did not show superiority of either hierarchy in terms of traversal time but the expandable hierarchy resulted in fewer errors to get to the target. Although older users significantly rated their computer and Internet experience lower than younger participants, experience did not alter the significance of age and hierarchy differences.

“…However, the expandable hierarchy needed fewer clicks to reach the target, probably due to the increased amount of contextual information. The age-related difference in speed but not in accuracy was in line with previous findings 9 . The traversal time may be affected by cognitive processing time differences since there were no significant age-related differences in click errors.…”
