Here the attributes are qualitatively different and can implicate either losses (e.g., costs to buy a bike) or gains (e.g., technical benefit of a bike). It has been suggested that these attributes values are integrated into a unified value currency to facilitate successful choice behavior (Montague & Berns, 2002; Heekeren et al., 2008). However, the exact neural mechanism of this value integration is still unknown. For decades, behavioral studies have assumed that the attributes’ value contribute independently to the overall subjective value. However, human behavior violates this assumption, implicating interactions between values. We investigated 24 healthy male subjects using functional magnetic resonance imaging (fMRI) with a task involving choices with multi-attribute options that consist of visual cues indicating physical pain (electrical pulse) and monetary reward. Different subjective-value models made similar predictions of choice-behavior, suggesting that behavioral data alone is insufficient to uncover the underlying integration mechanism. In contrast a direct model comparison on brain data decisively demonstrated that interactive value integration predicts neural activity significantly better than the independent mechanism. These results provide novel insights into the neurobiological underpinnings of human decision making involving the integration of different values.
