What is vection?

Vection refers to the phenomenon where an individual experiences an illusory sense of self-motion, even though they are not actually moving. This sensation typically arises when a person is in a stationary position but is surrounded by moving visual stimuli. For instance, if you are sitting in a stationary train and another train passes by at high speed, you might feel as though you are moving in the opposite direction, which is a classic example of vection.

Understanding vection is important in fields like psychology and virtual reality, as it highlights how visual cues can strongly influence our perception of motion and our spatial orientation. This concept is especially relevant in studies concerning how humans interpret dynamic information in their environment.

The other choices revolve around different perceptions and frameworks but do not encapsulate the essence of vection, which is specific to the illusory sense of self-motion.
