What characteristic is NOT likely to contribute to decreased alertness and increased worker fatigue?

High levels of stimulation are generally associated with increased alertness rather than decreased alertness and worker fatigue. When an individual is engaged in tasks that provide a lot of sensory information or challenges, this can promote a state of heightened awareness and focus. For instance, environments with dynamic and varied stimuli can keep a worker mentally engaged, reducing the risk of fatigue. In contrast, repetitive tasks, limited social interaction, and the requirement to stay in one position tend to create monotony and physical strain, which can lead to fatigue and decreased alertness. Therefore, high levels of stimulation stand out as the characteristic that is not likely to contribute to decreased alertness and increased worker fatigue.
