Understanding chimpanzee facial expression: insights into the evolution of communication
Open accessAbstract
To understand the evolution of emotional communication, comparative research on facial expression similarities between humans and related species is essential. Chimpanzees display a complex, flexible facial expression repertoire with many physical and functional similarities to humans. This paper reviews what is known about these facial expression repertoires, discusses the importance of social organization in understanding the meaning of different expressions, and introduces a new coding system, the ChimpFACS, and describes how it can be used to determine homologies between human and chimpanzee facial expressions. Finally, it reviews previous studies on the categorization of facial expressions by chimpanzees using computerized tasks, and discusses the importance of configural processing for this skill in both humans and chimpanzees. Future directions for understanding the evolution of emotional communication will include studies on the social function of facial expressions in ongoing social interactions, the development of facial expression communication and more studies that examine the perception of these important social signals.

In the citing paper
“Humans' closest relatives in the animal kingdom, namely chimpanzees, have strikingly similar underlying mimetic musculature in their faces (Parr and Waller, 2006).”
From Connecting minds and sharing emotions through mimicry: A neurocognitive model of emotional contagion (2017) · cites this paper as Parr and Waller, 2006
The check wasn’t confident either way, so it gives no verdict — never disputed.
In the citing paper
“Aversive responses, including feelings of fear or anxiety, are modulated by hardwired neural circuits that share common neuroarchitectures among mammals (Le Doux, 2012;Parr and Waller, 2006).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
