Design outcomes

Primary

Measure	Time frame
The main endpoint of the present study is the latency (reaction time) of the eye movement. This is measured as the time between the presentation of the target and the start of the eye movement.	—

Secondary

Measure	Time frame
The secondary study parameters are the saccade metrics like saccade trajectories and endpoint. Furthermore, it will be investigated whether the prismatic effect is more perceptual or more motor in nature, or a combination of both. The data for this will come from the neuropsychological neglect screening, in which changes in performance on screening tests with a strong perceptual component (e.g. Landmark task) will be compared to changes in performance on screening tests with a strong motor component (e.g. Star Cancelation). Additionally, differences in eye movements (reaction times, endpoints) between pre- and post prism adaptation will be investigated.	—
