How is acute fatigue primarily characterized?

Acute fatigue is primarily characterized by the presence of errors in timing and neglect of secondary tasks. This form of fatigue manifests itself in a decreased ability to concentrate and maintain attention, often leading to mistakes in tasks that require timing or multitasking. When someone experiences acute fatigue, cognitive functions can be impaired, making it tough to manage multiple responsibilities effectively at once.

While feeling drained but still able to perform reflects a certain level of fatigue, it does not capture the specific impact that acute fatigue has on task execution and cognitive function. Heightened emotional sensitivity can also accompany fatigue but is not a defining feature of acute fatigue itself. Similarly, loss of long-term memory functions is more associated with chronic fatigue or other cognitive disorders rather than acute fatigue, which typically affects immediate task performance more than long-term memory retrieval.
