Variations in stimulus parameters (distance between the parallels and angle of the transversal) in the Poggendorff illusion were used to explore possible reasons for inconsistencies in the age trends in illusion magnitude found in earlier studies. The data show that the Poggendorff illusion is very sensitive to parametric manipulations and that the age trends are quite different for different configurations of the stimulus array. Systematic sex differences in illusion magnitude were also found.
