Summary: Realistic, everyday rewards contain multiple components, such as taste and size. However, our reward valuations and the associated neural reward signals are single dimensional (vector to scalar transformation). Here, we present a protocol to

Recording from monkey orbitofrontal cortex, the authors used composite reward bundles and found individual neuron and population responses that were suitable for economic choice. The responses followed behavioral indifference curves and predicted beh

Rewarding choice options typically contain multiple components, but neural signals in single brain voxels are scalar and primarily vary up or down. In a previous study, we had designed reward bundles that contained the same two milkshakes with indepe

Classic neuro-economic studies suggest that people and animals alike assign values to individual attributes arriving at a total summed valuation and therefore overall appraisal of the offer (Kahnt et al., 2011; Lak et al., 2014). However, further wor

Rational choice, in all its definitions by various disciplines, allows agents to maximize utility. Formal axioms and simple choice designs are suitable for assessing rationality in monkeys. Their economic preferences are complete and transitive; the

Sensitivity to satiety constitutes a necessary requirement for claiming neuronal coding of subjective reward value. In the most natural and interpretable way, specific satiety arises from on-going consumption of individual rewards. Choices between di

Realistic, everyday rewards contain multiple components. An apple has taste and size. However, we choose in single dimensions, simply preferring some apples to others. How can such single-dimensional preference relationships refer to multi-component
