title: Cognition and higher vestibular disorders: developing tools for assessing vection.
abstract: Visually induced vection is the illusory sensation of self-motion caused by visual stimuli (such as a dot cloud) that emulate what is seen when an agent moves through space. The sufficient stimulus parameters to generate vection are unknown, but elucidating this is of interest in the study of higher (cognitive) neurological disorders where the relationship between visual and vestibular processing is disturbed. Here, we selectively eliminate that radial motion angle from vection displays and show that vection is still present, although weaker than during normal optic flow, and that vection strength was strikingly variable across individuals.
