fMRI tasks [under construction]

Below a diverse set of Presentation and E-Prime task scripts is provided under the GNU General Public License. Most of the Presentation tasks work with a so-called 'playlist' text file that specifies the task events (actions) and their parameters. The advantage of this approach is that event and stimulus order can be easily adapted or randomized and custom events can easily be added.

Food image viewing

Standardized food and non-food images can be obtained from the F4H Image Collection or other online resources like the FoodPics or FRIDa database. Note that images from the latter databases may not be optimized for use in fMRI tasks. It is highly recommended to obtain appropriate ratings from the different image categories, in particular liking and to pre-test images in your study population(s) (liking, familiarity, other parameters of interest).
