What factors increase the likelihood of experiencing visual illusions or spatial disorientation?

The choice indicating that all of the factors increase the likelihood of experiencing visual illusions or spatial disorientation is supported by how each element contributes to the challenges faced during nighttime operations or in low-light conditions.

Degraded visual acuity affects the clarity of the visual information being processed, making it more difficult for the individual to accurately interpret their surroundings. When vision is compromised, it is easier to misjudge distances, depth, or the position of objects, leading to potential illusions.

Fatigue significantly impacts cognitive and perceptual functions. When an individual is tired, their reaction times are slower, and their ability to focus diminishes. This reduced capacity for attention and processing can lead to confusion and misinterpretation of visual cues in the environment.

High task loading refers to situations where there is a high demand for mental resources, often due to multitasking or managing complex operations. Under such conditions, cognitive overload can occur, impairing an individual's judgment and leading to mistakes regarding spatial awareness.

Reduced Field of View (FOV) and inexperience are also important factors, as they limit the visual information available to the user and can contribute to misjudgments. However, the inclusion of both degraded visual acuity, fatigue, and high task loading combines to create a comprehensive understanding
