Acute fatigue may be evidenced by a learner's apparent?

Acute fatigue in learners can manifest in various ways, often reflecting a decline in their cognitive functioning and ability to manage multiple tasks effectively. When a learner shows a neglect of secondary tasks, it indicates that their mental resources are stretched thin, causing them to prioritize only essential activities or to become less capable of managing tasks that require additional cognitive effort or attention.

This behavior illustrates that the learner is struggling with fatigue, which hampers their ability to maintain focus on non-essential tasks. As fatigue sets in, the learner may become overwhelmed and unable to juggle various responsibilities, leading to an observable decline in performance regarding tasks that aren't immediately critical. In essence, this neglect signals that their cognitive load is too high and they are unable to handle the demands effectively, which is a direct consequence of acute fatigue.
