Abstract: Information Display Board (IDB) is a process tracing technique, which shows an m×n information matrix to subjects and monitors their information acquisition behavior. Researchers employ this technique to study subjects’ information searching and acquiring process in problem solving and decision-making. Mouselab is the generally adopted software of IDB and applied in many researches. Since consumers are problem solvers with bounded rationality, IDB is fitted for the studies of consumer behavior. Using IDB, the patterns of information acquisition and some influence factors were studied in consumer decision-making studies.

Key words: consumer decision, information acquisition, process tracing, IDB, Mouselab
