Predictions Under Sleep Restriction

We investigated the impact of sleep restriction on learning and inhibitory control in a predictable yet uncertain environment, focusing on built-up expectations. Using a Go/NoGo task with varying Go-stimuli probabilities, we compared Sleep-Restricted (SR) and Well-Rested (WR) participants. Both groups showed similar performance trends, but WR adapted better to changing probabilities. Surprisingly, we found no group differences in inhibitory control. A computational model revealed SR participants had diminished perception of environmental volatility, suggesting challenges in detecting task changes and updating beliefs.
