Argues that selecting data according to expected information gain, as proposed by M. Oaksford and N. Chater (1994, 1996), leads to suboptimal performance in Bayesian hypothesis testing. Procedures are presented that are better justified normatively, their psychological implications are explored, and a number of novel predictions are derived under…

Argues that Klauer's proposal (1999) and proposal presented are equally well justified from a normative perspective and that, where the predictions of the two approaches diverge, the existing empirical evidence is consistent with the information gain approach. Recommends that more empirical research is required to decide between these two…

When a person performs several activities at the same time, there is often competition for the processing resources required to do those activities. Recently, the authors developed a method for analyzing the tradeoffs that can occur when two or more tasks compete for the same limited resource. (Editor/RK)

Accounting for verbal reports requires explication of the mechanisms by which the reports are generated and influenced by experimental factors. We discuss different cognitive processes underlying verbalization and present a model of how subjects, when asked to think aloud, verbalize information from their short-term memory. (Author/GDC)
