The method of reproduction and Mueller-Lyer changes.
In a three-variable study of Mueller-Lyer decrement, each of eight independent groups of 10 subjects responded 30 times to one of the two Mueller-Lyer components by the Method of Reproduction. The mean of the initial Out response was significantly greater absolutely than that of the In response. All three interactions were significant. The In figure demonstrated illusion decrement across the 30 trials, but the Out figure demonstrated illusion increment.
