 ### Presenting a feedback to the participant 
 
-In Project Implicit, for eductional purpopses, at the end of many of our studies, participants see the common interpertation of their IAT result.  In experiments in other settings (e.g., in the lab), I usually don't do that. When we present feedback in Project Implicit's website, we provide much context to the participant, to make sure they don't think that the feedback is more than an educational tool. The IAT (like all the other "implicit measures") is not accurate enough to provide a reliable estimate of attitudes for each participant. Therefore, I strongly recommend not to present feedback to your participants.

 If really must present feedback, then you can use [this example](https://github.com/baranan/minno-tasks/tree/master/docs/studies/datapipe.iat.examples/show.iat.feedback), which shows how to do that. The relevant code appears in the file [lastpage.showresults.jst](https://github.com/baranan/minno-tasks/blob/master/docs/studies/datapipe.iat.examples/show.iat.feedback/lastpage.showresults.jst).
