This paper shows monkeys adjust their reward-effort decisions based on subjective effort costs influenced by prior experience, using a subtractive model of effort disutility.

The paper applies random utility modelling to study decision-making in non-human primates, showing how neuronal activity in the orbitofrontal cortex reflects utility and choice preferences in multi-component bundles.

The paper demonstrates that neural signals in reward-related brain regions follow choice indifference curves, indicating integration of multiple reward components into scalar signals.

This study shows that reward-specific satiety reduces subjective reward value signals in orbitofrontal cortex during multi-component economic choices.

The paper investigates how humans and monkeys make choices between multi-component rewards, showing that preferences can be represented as single-dimensional trade-offs using indifference curves and validated by machine learning.
