MouseTrace: a better mousetrap for catching decision processes.

This paper describes MouseTrace, a computer program designed to monitor the process by which people make decisions by presenting complex choice information to subjects in the form of an alternative-by-attribute matrix. MouseTrace is a Windows-based extension of another program called MouseLab; however, MouseTrace accommodates significantly more information and allows for multiple responses, as well as multiple decision stages. It is also easier to use for both subjects and experimenters and more sophisticated in terms of its features and the data it records. These data include what information was examined, when, and in what order. This information can be used to derive a variety of cognitive process measures, including those related to search depth, sequence, and content, which in turn can be used to provide unique insights into decision-making theory, individual differences, and a variety of decision variables.

Validating a new process tracing method for decision making.

In this paper, we describe two experiments in which we assessed the validity of phased narrowing, a new process tracing technique designed to help researchers better understand multiattribute evaluation processes. Specifically, in Experiment 1 we examined the distribution of choices across successive decision stages and the attitudes and perceptions of the decision maker. In Experiment 2, we examined a variety of process data generated via a computerized information monitoring program called Mouse-Trace. Comparisons, in all cases, are made between experimental conditions that do and do not require decision makers to narrow their choices across successive stages. Taken together, the data indicate that there is little evidence to doubt the validity of a less restrictive version of phased narrowing which allows subjects to choose their own number of options to include at each stage. These results are encouraging for researchers who plan to use the technique to study decision making in its natural context.

Organ donation terminology: are we communicating life or death?

The continued functioning of organ transplantation depends on obtaining the permission of the next of kin. This communication process between medical or transplant professionals and a donor family hinges heavily on the understanding of certain critical terms like brain dead, life support, and transplantation. Communication issues in obtaining organ donation consent were examined, with particular focus on what are literally life-and-death decisions. Using an experimental simulation methodology, data are offered in support of the claim that much miscommunication occurs in such situations. Directions for improving such communication by allaying latent fears and more carefully defining crucial terminology are offered.
