Which type of tasks are likely to contribute to decreased alertness and increased worker fatigue?

Tasks with repetitive characteristics are likely to contribute to decreased alertness and increased worker fatigue. When individuals engage in repetitive tasks, their mind and body can become accustomed to the routine, leading to a decline in engagement and cognitive stimulation. This monotony can result in reduced attentiveness, as the brain may enter a state of reduced alertness, making it more challenging to stay focused and vigilant.

In contrast, complex and varied tasks can keep workers mentally engaged and stimulated, helping to maintain their alertness. Tasks requiring minimal focus may not demand enough cognitive effort to induce fatigue, while tasks involving team collaboration typically foster interaction and stimulation, which can enhance alertness and reduce feelings of fatigue. Hence, the repetitive nature of certain tasks is the primary reason they are associated with increased fatigue and decreased alertness.
