The Muller-Lyer figures (wings-in, H type and wings-out) with the texture density gradient patterns (fine, plain and rough texture in the proximity of the shaft) were constructed by many parallel lines (2, 4 and 8 lines) to the shaft of the Muller-Lyer figure. The apparent shaft lengths of these modified Muller-Lyer figures were estimated by fifteen university students. The illusion magnitudes were not influenced by the texture density gradient patterns. These data consisted with the previous researches. These results were interpreted as inconsistent with an account of Muller-Lyer illusion in term of the perspective theory, since the predictions of the constancy scaling, the systematic changes in the illusion magnitudes to be associated with the systematic changes in the depth cues, were not confirmed.
