AI-generated face images of emotional expressions
Recently developed artificial intelligence (AI) tools are now capable of generating realistic face images that are indistinguishable from photographs. However, little is known regarding how these synthetic images portray emotional expressions. Here, with only simple prompting, we generated a set of images depicting seven facial expressions using ChatGPT. These images were intermixed with posed facial expression photographs drawn from a standardis…
Pseudoreplication in Primate Communication Research: 10 Years On
Pseudoreplication is the statistical error of collecting numerous datapoints from a single unit (such as an individual), which are not independent, and applying statistical methods that assume independence of data. Importantly, pseudoreplication increases the chances of Type 1 errors (i.e., false positives), bringing findings and conclusions based on pseudoreplicated analyses into question. Ten years ago, Waller et al. (2013) published a paper hi…
The face is central to primate multicomponent signals
A wealth of experimental and observational evidence suggests that faces have become increasingly important in the communication system of primates over evolutionary time and that both the static and moveable aspects of faces convey considerable information. Therefore, whenever there is a visual component to any multicomponent signal the face is potentially relevant. However, the role of the face is not always considered in primate multicomponent …
Morphological variants of silent bared‐teeth displays have different social interaction outcomes in crested macaques ( Macaca nigra )
OBJECTIVES: While it has been demonstrated that even subtle variation in human facial expressions can lead to significant changes in the meaning and function of expressions, relatively few studies have examined primate facial expressions using similarly objective and rigorous analysis. Construction of primate facial expression repertoires may, therefore, be oversimplified, with expressions often arbitrarily pooled and/or split into subjective pig…
