The DSMAC (Dynamic Sequential MultiAttribute Choice) interface is a process-tracing methodology that permits a researcher to investigate subjects’ behaviors in an optional-stopping task. In such an environment, an individual decides after each piece of acquired information whether to make a choice between a pair of competing alternatives or to acquire additional information. DSMAC consists of two modules-an experimenter and a subject interface. The former allows the researcher to specify all of the relevant experimental parameters for a particular study, which is subsequently used as input by the latter. The bimodular nature of DSMAC significantly reduces the set-up time required for constructing novel stimuli for new experiments. DSMAC runs on a Macintosh computer. It is compatible with most Mactintosh models that use a system 7.0 (or higher) operating system. The source code was written in ThinkPascal 4.0.1.
