One solution is to give up entirely the use of such software in favor of a low-level programming language. Here we show how E-Prime can be connected to Mathematica so that the easiness and reliability of this software can be preserved while at the same time granting it the full computational power of a high-level programming language. As an example, we show how to generate noisy images with noise proportional to the rate of success of the participants with as few as 12 lines of codes in E-Prime. http://www.tqmp.org/Content/vol05-2/p059/p059.pdf Experiment programming
