title: Learning the value of money from stochastically varying prices.
abstract: In 3 experiments, the authors investigated learning of the value of money from product prices in an unfamiliar currency when the prices are proportional to quantity. In support of the second stage of a hypothesized 2-stage process of learning, Experiment 1, in which 32 undergraduates participated, shows that response times for inferences of quantity are longer when participants are presented with quantity-price pairs than when they are presented with price-quantity pairs. Experiments 2 and 3, in which 54 and 34 undergraduates participated, respectively, show that (a) stochastic price variation causes systematic errors in the learning of unit prices from quantity-price pairs as a result of judgmental regression effects and (b) in support of the 2-stage learning hypothesis, inferences of quantity are the inverse of the learned unit prices.
