To use the system you need to take a test after training. This ensures that all users are coding in the same way, and so maintains the standardisation of the system.

Please notice that you can attempt the GibbonFACS Test several times if you don't pass initially. For each additional attempt, however, you may need to wait for several weeks to receive your scores, especially during busy periods. It is also important that the trainee takes enough time to revise the Manual before a second attempt.
After becoming GibbonFACS certified, the coder will be able to reliably code facial movements in videos and pictures of hylobatids. High quality close-ups of the face should ideally be recorded and pictures must be compared with the neutral face of each individual, accounting for individual variation. Depending on the purpose of coding, two or more cameras should be used in synchrony (e.g. one camera zoomed in on the face and other camera recording body and context behaviours).
The GibbonFACS can be applied to investigate communication and emotion in cats through the analyses of the individual facial behaviour.
GibbonFACS was developed thanks to the joint effort of:
The authors thank Robert Zingg and Zoo Zurich (Switzerland), Jennifer Spalton and Twycross Zoo (UK), Neil Spooner & Matt Ford and Howletts Wild Animal Park (UK), Corinne Di Trani and Mulhouse Zoo (France) for allowing us to collect footage of their animals. We also thank Gill Vale for support in collecting some of the video footage, Cátia Caeiro for reliability coding and Wiebke Hoffmann for general assistance.
