In the present study, the strength of hollow-face illusion was measured using psychophysical method (computer controlled double-staircase). Stimuli were threedimensional stereo images of laser scanned female face, rendered varying facial texture (positive, negative or no texture), stimulus orientation (upright or inverted), and light direction (top- or bottom-lit). Three-factorial experimental design investigated how these factors affect the illusion. The results showed the significant main effects of all factors. Hollow-face illusion was stronger for the stimulus with positive texture than with the negative or no texture. Upright face showed stronger illusion than inverted. Light from bottom increased illusion as compared with the light from top. First order interactions showed that the effect of texture was significant only for the upright face, and that the effect of light direction reversed if the stimulus orientation was inverted. In addition, second order interaction showed that the light direction had no effect for inverted negative face. These interaction patterns were complex, but were explained simply in terms of the tendency that the more face like pattern causes the more hollow-face illusion.
