Table 3. Results of Experiment 2.
Model selection in the domain of gains and losses in Experiment 2. ADD indicates the basic structure of the equation is additive whereas MULTI indicates the basic structure of the equation is multiplicative. The number following ADD or MULTI indicates the number of free parameters in the model. Model names suffixed “R” indicates the scaling parameter is applied only to the delay or odds against variables rather than the entire denominator (see Table 1 for details).
