MaqFacs
We have collaborated with researchers here in the US and in the UK to develop a Facial Action Coding System for rhesus macaques, aka MaqFACS. This system is based on the well-known human FACS (Ekman & Friesen, 1978), and modeled closely after the recent development of the chimpanzee FACS (ChimpFACS, Vick et al., 2007). The three main steps were to first establish the presence and general location of each of the mimetic facial muscles in the rhesus macaque (Burrows et al., 2009). Second, verify the movement changes associated with activation of these muscles using intramuscular stimulations (Waller et al., 2008). And finally to verify the presence of these movements in naturally occurring rhesus monkey behavior and assign these movements the appropriate action unit code (Parr et al., in prep). A manual has been created which you can preview or register to download below. This provides a means for others to learn this system, providing an objective and standardized tool for assessing facial movement that is biologically comparable to humans and chimpanzees.

The Final MaqFACS test is now available. Please email Dr. Parr.
Please use academic discretion with this manual and accompanying materials. The FACS, ChimpFACS and MaqFACS are standardized systems. Individuals are required to pass a test for certification in order to use these systems. Your cooperation is appreciated. Enjoy.
