Brügger et al. (Science Advances, 7, eabc8790, 2021) recently introduced the use of remote thermography to investigate how monkeys process socially significant vocalizations. This is a welcome addition to the arsenal of comparative psychologists. Interpretative issues abound, but the ability to non-invasively measure physiological responses that do not immediately result in overt behavior opens interesting lines of investigation.
