“…Indeed, similar systematically controlled experimentation on great apes would clarify the extent to which these primates are also prone to human-like contagious yawning. The existence of a 'possible facilitative' effect of seeing another individual yawn has been alluded to in macaques (Hadidian 1980). However, with the exception of tense male-male situations (Darwin 1872(Darwin /1999Adams & Schoel 1982) in which yawning may be triggered as a 'canine contest', until now there has been no evidence for the experimental elicitation of yawning by visual conspecific stimuli in non-ape primates.…”

This study reports the first experimental exploration of possible contagious yawning in monkeys. Twenty-two stumptail macaques (Macaca arctoides) were presented with video clips of either yawns or control mouth movements by conspecifics. At a group level, monkeys yawned significantly more often during and just after the yawn tape than the control tape. Supplementary analysis revealed that the yawn tape also elicited significantly more self-directed scratching responses than the control tape, which suggests that yawning might have been caused by tension arising from viewing the yawn tape. Understanding to what extent the observed effect resembles contagious yawning as found in humans and chimpanzees requires more detailed experimentation.

“…We chose to focus on describing adults at the expense of other age classes, as research has suggested that some of the diagnostic features of Sulawesi macaques may be fully developed only in adults [Hadidian, 1980]. In addition, adults are larger and therefore have a larger surface area of diagnosable features.…”

“…All Sulawesi macaques studied are highly frugivorous, although leaves, flowers, invertebrates, and possibly small vertebrates are also eaten [Muskita, 1988;Zahrah, 1988;Hadi, 1989;Supriyadi, 1989;Supriatna, 1991;Kohlhaas, 1993]. Behaviorally, Sulawesi macaques share a number of highly developed and unusual facial expressions and patterns of affiliative embracing and reconciliation [Dixson, 1977;Hadidian, 1980;Thierry, 1984Thierry, , 1985aThierry, , 1986Baker & Estep, 1985;Herrenschmidt, 1985;Baker & Bynum, 1989;Petit & Thierry, 1994a, b]. Sexual patterns appear to be broadly similar in Sulawesi macaque taxa studied to date [Dixson, 1977;Thierry, 1986;Baker & Bynum, 1989;Thierry et al 1994].…”

“…In all the species of nonhuman primates for which data on sex differences in the frequency of yawning are reported, males yawn much more than females (Bertrand 1969;Deputte 1978; Goy and Resko 1972;Hadidian 1980;HA and DeVore 1965;Redican 1975;Rinaldi 1985;Wolfheim and Rowell 1972). This différence has been related to sexual dimorphism in canine size: The larger size of male canines may make the male yawn a more effective threat.…”
