ABSTRACT Four different value laws are developed and tested by using them to predict the scale value of composite stimuli from the scale values of their components. These four laws are an additive law, a square‐root law, a logarithmic and a negative exponential law. They are tried out on a set of food preferences by means of Pearson's method of false position. The negative exponential law of diminishing returns gave the best fit to the data but was not markedly better than any of the other laws.
