Oddball experiment design in E-prime I want to set up an experiment in which there are 3 types of emotional stimuli (A, B, C). A and C would have a 1% recurrence probability, for rare and unexpected stimuli. Is there any sample of oddball paradigm for E-Prime?
Pstnet, the editor of Eprime, does not provide a sample for oddball paradigms. And sharing Eprime scripts is rare but you may find a script of interest here

This is part of an initiative described at http://www.birncommunity.org/resources/tools/fire-primer/multi-site-cognitive-paradigms-for-fmri-studies. File summaries are here http://www.nitrc.org/projects/fbirn (click on "see all files"). This auditory oddball file is far from being a sample though.
