ABSTRACT
This paper examines order effects and frequency learning in belief updating. We present an experiment that tests for the existence of order effects for actual decisions during frequency learning and for belief evaluations after frequency learning in a realistic tactical decision making task. The experiment revealed that (a) subjects showed order effects for actual decisions during frequency learning—an effect not reported previously and (b) subjects still showed order effects for belief evaluations even after having correctly learned most of the frequency information. We also present a simulation for the frequency learning behavior and some preliminary results of a simulation for the order effect, and suggest networks for potential combinations of the order effect and frequency learning.
