By = continuous, I mean a rating scale that is not discretized. For example, say= we have a recognition memory task in which subjects are presented with old= or new stimuli. The discretized version might have response options "defin= itely old", "maybe old", "maybe new" "definitely new", whereas the continuo= us version might require subjects to use a slider going from 0 to 1. By for= mally, I mean that the model was actually fitted to the continuous ratings = and not to the data after artificially discretizing them, for example into = quartiles. -- Samuel R.
