Subjects were asked to pick up the central disk on the left if the two central disks appeared identical in size, and to pick up the central disk on the right if they appeared different in size
The experimenters varied the relative sizes of the two target disks randomly so that in some trials physically different disks appeared perceptually identical in size, while in other trials physically identical disks appeared perceptually different in size
Summary
Edited by: Aleksandra Mroczko-Wasowicz, National Yang Ming University, Taiwan Reviewed by: Joshua Shepherd, Florida State University, USA. The effect of the illusion was significantly less pronounced with respect to action, as measured by maximum grip aperture (MGA) in prehension, than with respect to conscious perceptual estimation (PE), as measured by the distance between thumb and forefinger in a manual estimate of disk size.
