Too little time?: time constraints and time pressure in information search

People often experience time pressure when searching, yet the impact of time pressure on search behaviors and outcomes has not been studied extensively by the information science and information retrieval communities. In addition, experimental interactive information retrieval studies often include researcher-imposed time limits that may influence participants' search behavior and outcome measures in ways that are not well understood. This research proposes a systematic investigation of imposed time constraints on frequently used interaction measures and participants' perceptions of the search process and outcome.
