I have one more suggestion: Consult a local statistician. Psychology, neuroscience (and a host of other professions that I have encountered) are full of bad statistical practice and reinvention of wheels. "Vincentizing" sounds suspiciously like such an example. A statistician could help you sort it out and either validate the methodology or point you to equivalent more standard versions (and R packages or functions that might implement them) or other better alternatives.
Psychology and neuroscience are in particular undergoing public soul searching regarding their research methodology and the irreproducibility of many of their published results. Don't add to the problem: get help from someone local with the necessary statistical expertise. Cheers, Bert Bert Gunter Genentech Nonclinical Biostatistics (650) 467-7374 "Data is not information.
