Effort Expenditure for Reward Task
Test Variations
The Effort Expenditure for Reward Task as described in Treadway et al (2009) measuring motivation and anhedonia.
The the Cognitive Effort Expenditure for Rewards Task (cEEfRT) is a measure of reward motivation for cognitive work (Gamundi & Wardle, 2018).
