The glucose preference of four squirrel monkeys was determined by presenting 5-, 10-, 20-, 30-, and 40-percent solutions according to the paired comparison method. Scaling of the data for the amounts of each solution consumed yielded a preference function which increased monotonically with the concentration of the solutions.
