#Note/Permanent #CognitiveScience/CognitiveFatigue [[Understanding Cognition - The Bedrock of Mental Processing|Cognition]] is a foundational mental process that enables us to understand and interact with the world, facilitating personal growth and social engagement. A key aspect of this process is what we refer to as cognitive resources, which represent our current capacity for cognitive processing. When these resources are depleted, we experience a state commonly known as cognitive fatigue (CF)[^1]. This state is characterized by reduced ability to concentrate, slower information processing, and a diminished capacity for action. It's often felt as mental exhaustion after an intense day of cognitive activity, such as work, distinct from physical tiredness or sleepiness. Generally CF is a short-term condition that can be relieved with rest and breaks. >[!What is cognitive fatigue?] >Mental or Cognitive Fatigue (CF) can be defined as the decrease in cognitive resources developing over time on sustained cognitive demands, independently of sleepiness, which leads to difficulties to suppress irrelevant information during selective attention, increased perseverations and time needed to plan, weakened cognitive control and decreased high-level information processing, or even declining physical performance. > Understanding cognitive fatigue is crucial for recognizing its onset, comprehending its effects, and implementing strategies to mitigate it. Effective management of cognitive fatigue is key to maintaining productivity and mental well-being.
