- Reaction times - Abjustment task - Landmark task
The Oppel-Kundt illusion is used to distort the representation of space in healthy subjects and neglect patients.
Several different tasks are used:
The distotion of space in neglect patients is also investigated with respect to the third dimension.
To study the effects of perspective, we use another well-known visual illusion, the Ponzo illusion.
