Does anyone know how to perform DDM analysis on a multiple choice experiment? We conducted a four choice random dot-motion experiment, and wonder if anyone knows how to do this analysis. I know DDM is for two forced choices but according to this paper : Article Multialternative drift-diffusion model predicts the relation...
More choices can also be applied to this model.
Any suggestions would be appreciated.
Hi Eivinid
If you want model your experiments just mathematically, use this paper (Ratcliff & Childers (2015)) and some of its references that you can find yourself. you can generalize the equations in this paper with a little effort to equations for more than 2 choices. But if you want to visualize the process, I have some ideas I can share with you.
