Subjective value toward an object is ordinarily formed on the basis of a composite of relevant informations concerning with the object. Three mathematical models were described about the functional relationship between the overall value and the values of individual informations: additive, negative exponential, and positive exponential. All the empirical data presented (preferences towards electric washer, sewing machine, dishwasher, and evaluation of intelligence and of capability of housewives) were accounted for in either of the three functions. Of the respective functional forms, mathematical models were presented about the underlying psychological processes and implications of this analysis in marketing research were also discussed.
