• Assessing the link between reading/writing direction and perception of the corridor illusion

The corridor illusion induces a sense of depth and makes the brain perceived equally size objects as larger when placed in the background of a corridor and smaller in the foreground. Previous experiments[1] used corridor illusion to demonstrate that illusion strength depends on reading/writing habits. In my experiment, I will be investigating if the direction of visual scanning monitored with eye tracking will affect illusion strength. Secondly, I will investigate the corridor illusion in bilinguals. The research is essential in understanding the role of cultural factors like reading/writing habit in visual perception. More importantly, a study[2] concluded that visual illusions are a useful tool at exploring brain mechanism in DD. If the result of the project shows a clear link between corridor illusions and reading abilities, this could lead to further researches into corridor illusions in DD subjects, as there are no researches on DD susceptibility to corridor illusion.
