Creation and traversal of links in a user adaptable menu was examined for syntagmatically and paradigmatically related targets. One group searched for paradigmatic related targets within the same intermediate category under different superordinate categories, while another searched for syntagmatic related targets belonging to different intermediate catgories under the same superordinate. Users with syntagmatic targets created and traversed more superordinate category links, while users with paradigmatic targets traversed more intermediate category links. As predicted, more horizontal links at the same hierarchical level were created and traversed than diagonal links joining different levels. Overall, users tended to create links forming hierarchical networks.
