I'm currently analysing a parametric fmri study. In the first instance, I
try to analyse the neural responses correlated to the attractiveness of
three different stimuli.
Prior to the scanning I obtained modulatory parameters (with 3 stages) of
three different questionaires. Thus, each questionnaire gave me a different
(interval-scaled) ranking of stimuli, later used in the fmri study. This
ranking represents the attractivness of the stimuli.
So my second question is: Which questionaire best detects the attractivness?
Does anybody have a suggestion how to answer this second question?
Thanks for any suggestions!
