Pausal Behavior of End-Users in Online Searching.
Peer reviewed Peer reviewed
Huang, Mu-hsuan – Information Processing & Management, 2003
Uses an information processing approach to analyze the pausal behavior of end-users and identifies reasons for pausing, location of pauses, hesitation rate and pausal behavior changes over time. Confirms that searchers pause less frequently and for shorter periods as they progressed through searches over time. (Author/AEF)
