The effects of five procedures on the acquisition of conservation of length were studied. A Müller‐Lyer illusion was used to induce apparent changes in length in the test‐ and practice‐situations. Two procedures involved practice on addition‐subtraction, one a progressive increase in the strength of the Müller‐Lyer illusion, and one the anticipation of the outcome of displacements of the objects. A fifth procedure was a composite of the other four. The results showed some acquisitions in all groups, with highest frequency in the anticipation group, and lowest in the increase‐in‐illusion group.
