In between attacks, people with migraine report experiencing both visual discomfort and visual illusions induced by stationary high contrast striped patterns. Since both visual illusion and discomfort have been assessed through largely qualitative self-report, it is unclear how their mechanisms might be related with each other. This thesis aimed to investigate whether subjective reports of visual discomfort in people with migraine are associated with the strength of a motion illusion outside attacks. To determine the stimulus for motion illusion strength to be quantified, Experiment 1 measured the physical motion speeds that cancelled the illusory motion effect of five variants of the Frase..
