Final answer:
Jun is most likely to notice the exit sign when his attention is least distracted, which is when he is focused on the scenery and enjoying the view. This is because his mental load is lower and not preoccupied with more demanding tasks.
Step-by-step explanation:
The question is related to studying attention in psychology. Jun is most likely to notice the sign for the exit that he needs to take when he is least distracted. Among the given options:
- When he's listening to a captivating audiobook, his attention will likely be consumed by the story.
- When he's engaged in a deep conversation with his brother, his cognitive resources will be invested in the conversation.
- When he's focused on the scenery and enjoying the view, his visual attention is directed outside, but it's not as demanding as an engrossing audiobook or conversation, making this the scenario where he is least occupied with other tasks.
- When he's experiencing drowsiness and fatigue, his overall alertness and ability to pay attention are compromised.
Therefore, option c—when he's focused on the scenery and enjoying the view—is the scenario where he is most likely to notice the exit sign, as his mental load is lower compared to the other more cognitively engaging activities.
