Which of the following is NOT a task contributor to decreased alertness?

The correct answer is that tasks requiring social interaction do not typically contribute to decreased alertness. In fact, engaging with others can often enhance alertness and focus. Social interaction stimulates cognitive processes and can help maintain interest and motivation, which are important for sustaining attention and energy levels.

In contrast, tasks with a high demand for focus can lead to mental fatigue, as they require continuous concentration. Repetitive tasks can become monotonous and may cause disengagement or drowsiness over time. Similarly, staying in one position for extended periods can result in physical discomfort or fatigue, further diminishing alertness. Therefore, among the options given, tasks requiring social interaction stand out as the one least likely to lead to decreased alertness.
