[Face-research-list] question on validation

Dear List Members: I am wondering how to validate general facial expressions. I see a single method: - estimate the amplitude of action units *AND* get a FACS expert who validates the data (and does not mind emotions at all) Do you have any other idea? - Are you aware of any kind of database where people respond naturally to images or sounds and they also talk about their mixed feelings? - Is there any kind of image database on facial expressions with regard to a standard emotional database, like IAPS? - Is there any general measure, such as co-measured signals (like video, fMRI, PET, EEG and gaze estimation) together with the data that was used to evoke emotions in the study and can be used for validation? I am very much looking forward to your responses.
