A study by the researchers at the Kessler Foundation that has implications on the connection between brain disease and cognitive fatigue. Dr. Wylie, who is associate director of Neuroscience Research and the Rocco Ortenzio Neuroimaging Center at Kessler Foundation wrote "We challenged participants with difficult tasks of working memory, and assessed which parts of the anterior cingulate cortex were associated with error processing," "We then investigated whether exactly the same areas of the anterior cingulate cortex were also associated with fatigue. They were, suggesting that cognitive fatigue may be the brain's way of signalling to itself that the effort required for the task no longer merits the rewards received." This showed that patients with multiple sclerosis, brain injury, stroke and Parkinson disease are more subjectable to Mental Fatigue.
The targets of mental fatigue can be just anyone who has an active life and a stressful job or even an active life in a modern urban environment.
On the other hand, another study states that there is an increasing amount of evidence that during mental fatigue, shifts in motivation drive performance rather than reductions in finite mental energy. So far, studies that investigated such an approach have mainly focused on cognitive indicators of task engagement that were measured during controlled tasks, offering limited to no alternative stimuli. So, it is possible that attention is diverted to stimuli that are unrelated to the task, or whether fatigued individuals still focused on the task but were unable to use their cognitive resources efficiently.
To manage the workforce and keep performance at a peak, big companies hire expensive human resources directors and teams to keep up with team performance and detect early signs of fatigue among other situations that might require any kind of intervention.
When we approach small and medium enterprises they not only don’t have the resources for a high-performance HR team but they also expect the best and upmost dedication from their teams. Unfortunately, this single-minded focus on the outcome and the service provided blinds managers to mental fatigue symptoms until sometimes it is to late. That is where fatigue management applications can make a huge difference. Not only by alerting managers of small teams but also in large companies as an advanced sensor that can trigger action from the team earlier and keep performance and motivation to a top level without the need to make changes on the motivational cost/reward trade-offs level while also mitigating long term effects of mental fatigue that can expand to absenteeism and in worst cases depression.
