What type of stress can make crew members more likely to stare at objects?

Alcohol consumption can impair cognitive functions and motor skills, leading to issues with attention and focus. When crew members consume alcohol, it can result in slower reaction times and decreased awareness of their surroundings. This impairment may manifest as staring at objects, as the individual’s processing abilities are affected, making it challenging to shift attention or respond to stimuli.

Fatigue, while it can also affect attention, typically results in reduced alertness and a propensity for errors rather than a specific behavior of staring. Overexertion may cause a crew member to feel physically drained, leading to distraction or decreased focus, yet it's not directly linked to the act of staring. Hypoxia, a condition resulting from inadequate oxygen supply, can lead to confusion, dizziness, and other severe symptoms, but the specific behavior of staring is more closely associated with the cognitive impairments linked to alcohol consumption.
