Abstract

The predictions of M. Oaksford and N. Chater's (1994) optimal data selection (ODS) model for the reduced array selection task (RAST) were tested in 4 experiments. Participants tested a hypothesis, if p then q, by selecting cards showing q or not q instances. In Experiment 1, where selections were made from different sized stacks of q and not q cards, as P(q) increased, not q card selections rose, and q card selections fell, as predicted. Experiment 2 controlled for the possibility that stack height influenced responses; these results were also consistent with ODS. Experiment 3, which controlled further for this possibility, replicated Experiment 1. Experiment 4 addressed a final issue concerning the medium P(q) condition by concentrating on initial card selections; the results were again consistent with ODS. Although generally consistent with the ODS model, these experiments also suggest some interesting revisions.
