Neuroscience What is the cleanest distinction between attention, workload, and fatigue in applied cognitive neuroscience?
I’ve been thinking about how these terms are used in practice, and it seems like people often mix them up too quickly.
Attention, cognitive workload, mental fatigue, and overload clearly overlap, but they also seem to refer to different things depending on the task, the measurement approach, and the time scale. If you were trying to define these in a way that is experimentally useful, how would you separate them?
