The Ratcliff Diffusion Model: extensions and an application to an IAT experiment

| Abstract: |
Reaction time and accuracy data typically violate the assumptions needed for classical linear modeling. The diffusion process is a theoretical representation of the internal decision process, which allows to simultaneously analyze reaction time and accuracy data, without having to deal with violations of assumptions. We present some extensions of this technique, and focus on one extension that makes it possible to fit diffusion models to more than one data set (or experimental condition) simultaneously. We discuss applications of the model in the field of emotion psychology (the Implicit Association Test and trait anger). |
