Behavioral and Neural Representations of Subjective Effort Cost
Sponsor: Hugo W. Moser Research Institute at Kennedy Krieger, Inc.
Summary
The goal of this proposal is to understand the common and distinct behavioral and neural representations of subjective effort valuation, and how these representations are influenced by fatigue and changes in motivation. It is hypothesized that the brain will use overlapping and distinct neural circuits to represent cognitive and physical effort value, and that fatigue and enhanced motivation will influence the subjective value of effort.

Interventions
Cognitive Fatigue
Participants will perform a cognitively demanding task (spatial attention task), repeatedly, to induce cognitive fatigue.
Physical Fatigue
Participants will perform a physically demanding task (grip force exertion task), repeatedly, to induce cognitive fatigue.
Rewarding Stimuli
Reward-associated stimuli will be used to study how reward-induced changes in motivational state influence effort choices.
