Abstract
A reciprocal, closed-loop-controlled aiming task was used to determine the influence of visual illusion effects on the perception-action coupling. The visual illusions were induced by a size-contrast illusion (Ebbinghaus-Titchener- Illusion). Additionally, a Fitts' task with different indexes of difficulty (IDs 3, 4.5) was used to manipulate the movement difficulty. The task was to move a cursor with an extension-flexion movement over 30 s as accurately and fast as possible between two circles of the same size. However, these target circles were surrounded by smaller or bigger circles to induce the different visual illusions. The results indicate that the visual illusions (the perceived target seems smaller as it is) as well as an increase in the ID in the Fitts' task degrade performance on the response outcome measures. The findings provide empirical evidence that visual illusions degrade performance in a closed-loop-controlled, reciprocal aiming task.
