This study uses fMRI to investigate how brain regions like the supplementary motor area and anterior midcingulate cortex contribute to effort perception during pain and task performance.

The paper replicates a previous finding that cognitive effort is influenced by reward rate but shows that recent performance history better explains effort allocation, suggesting a reinterpretation of prior results.

This study uses meta-analysis to show that mPFC/dACC processes task demand and reward separately, with caudal regions integrating them to reflect cost-benefit trade-offs in effort investment.

This study uses tDCS to show that stimulating the Frontopolar Cortex reduces cognitive effort costs in a sequential decision task, supporting its role in motivating effortful behavior.

The paper examines context-dependent choice in real-world settings using restaurant rating data, finding that valuations and choices are influenced by the context of available options.

This study examines how acute stress affects the balance between model-based and model-free reinforcement learning in pathological gamblers and healthy controls, finding stress impacts this balance more in controls than gamblers.

This paper investigates how the opportunity cost of time modulates cognitive effort in various tasks, finding that higher time costs lead to faster responses and more errors, indicating reduced cognitive effort.

The paper uses fMRI to show that offline replay of trajectories and uncertainty sensitivity support planning during reward revaluation.
