To describe the attitudes of subjects toward risk, Lopes proposed the two-factor model (SP/A): The work presented here uses this model as a framework. It suggests a series of modifications of the stimuli used for data collection and of the measurement of the basic attitude of the subjects toward risk with those stimuli. However, the central scope of the present work is in the formalization of the two-factor model. Also, it is developed and tested empirically through a linear additive model. The results obtained indicate that the modifications in the material used do not alter the response patterns, and that they are compatible with the proposed model.
