What is it about?
We are investigating how the mental fatigue we experience in daily life influences our decision to put effort into tasks. Specifically, we look at how the fear of 'punishment' or negative consequences (avoidance instructions) can change how we manage our energy. Does the threat of a penalty push us to work harder even when we are exhausted, or does fatigue eventually take over?

Why is it important?
This research offers a practical framework for understanding how we can overcome the mental 'wall' we hit at the end of a long day. By showing how external motivation can counterbalance fatigue, these findings could help design better strategies for maintaining healthy habits or productivity.
Perspectives
Looking ahead, I am interested in taking this research further by incorporating brain-imaging techniques to better understand the neural mechanisms behind these effort-based decisions. Additionally, I want to explore how modern factors, such as social media consumption, contribute to daily cognitive fatigue and influence our choices. By linking neurobiological data with real-world digital habits, we can develop a more comprehensive view of how motivation and fatigue interact in the 21st century.
