ABSTRACT
We constructed a virtual psychology laboratory (called VPL) on a computer. VPL simulates the process of pair subjects collaboratively solving Wason’s 2-4-6 task, which has been traditionally used in the field of the psychology of discovery science. Participants were required to study collaborative problem solving while repeating experiments and hypothesis revisions using VPL. We conducted three experimental sessions using VPL. As a result, we confirmed, across the sessions, the improvement in various types of participant’ performance, such as the organizational construction of experimental design, the degree of correctness of hypotheses the participants formed, and the generality of findings they discovered.
