“…Common marmosets are known to cock their head in reaction to the appearance of new objects (e.g., flies, pieces of food), or other individuals (“head-cock staring”) like cage mates or human strangers (Menzel and Menzel 1980 ). It is more frequent when directed towards living beings (Cantalupo et al 2002 ) and it gradually decreases in frequency with age (Kaplan and Rogers 2006 ). The functional significance of head-cocking in primates remains unclear.…”

“…The rotation was exhibited either clockwise or counterclockwise, without a significant difference between the two. Previous reports of head-cocking in marmosets and other primates (Rogers et al 1993;Kaplan and Rogers 2006;Cantalupo et al 2002) described this movement as a fast saccadic counter rotation of the head back to the upright position. However, the head-cocking we recorded preceded gaze aversion and did not involve an intermediate return of the head to the upright position.…”

A prosocial function of head-gaze aversion and head-cocking in common marmosets

Gaze aversion is a behavior adopted by several mammalian and non-mammalian species in response to eye contact, and is usually interpreted as a reaction to a perceived threat. Unlike many other primate species, common marmosets (Callithrix jacchus) are thought to have a high tolerance for direct gaze, barely exhibiting gaze avoidance towards conspecifics and humans. Here we show that this does not hold for marmosets interacting with a familiar experimenter who suddenly establishes eye contact in a playful interaction (peekaboo). Video footage synchronously recorded from the perspective of the marmoset and the experimenter showed that the monkeys consistently alternated between eye contact and head-gaze aversion, and that these responses were often preceded by head-cocking. We hypothesize that this behavioral strategy helps marmosets to temporarily disengage from emotionally overwhelming social stimulation due to sight of another individual’s face, in order to prepare for a new round of affiliative face-to-face interactions.

Gaze aversion is a behavior adopted by several mammalian and non-mammalian species in response to eye contact and usually interpreted as reaction to perceived threat. Unlike many other primates, common marmosets (Callithrix jacchus) are thought to have high tolerance for direct gaze, barely exhibiting gaze avoidance towards conspecifics and humans. Here we show that this does not hold for marmosets interacting with a familiar experimenter who suddenly establishes eye contact in a playful interaction (peek-a-boo game). In video footage synchronously recorded from the two agents, we found that our monkeys consistently alternated between eye contact and head-gaze aversion. The striking similarity with the gaze aversion dynamics exhibited by human infants interacting with their caregivers suggests a shared behavioral strategy to disengage temporarily from overwhelming social stimulation, in order to prepare for a new round of rewarding, affiliative face-to-face interaction. The potential of our finding for a marmoset model of autism is discussed.

Young animals are known to direct alarm calls at a wider range of species than adults. Our field study examined age-related differences in the snake-directed antipredator behavior of infant, juvenile, and adult white-faced capuchin monkeys (Cebus capucinus) in terms of alarm calling, looking behavior, and aggressive behavior. In the first experiment, we exposed infant and juvenile white-faced capuchins to realistic-looking inflatable models of their two snake predators, the boa constrictior (Boa constrictor) and neotropical rattlesnake (Crotalus durissus) and a white airplane as a novel control. In the second experiment, infants, juveniles, and adults were presented photographic models of a coiled boa constrictor, rattlesnake, indigo snake (Drymarchon corais), a noncapuchin predator, and a white snake-like model. We found that antipredator behavior changed during the immature stage. Infants as young as 4 months old were able to recognize snakes and display antipredator behavior, but engaged in less snake-model discrimination than juveniles. All age classes exhibited a lower response to the white snake-like model, indicating that the absence of color and snake-scale patterns affected snake recognition. Infants also showed a higher level of vigilance after snake-model detection as exhibited by a higher proportion of time spent looking and head cocking at the models. Aggressive antipredator behavior was found in all age classes, but was more prevalent in juveniles and adults than infants. This study adds to the knowledge of development of antipredator behavior in primates by showing that, although alarm calling behavior and predator recognition appear at a very young age in capuchins, snake-species discrimination does not become apparent until the juvenile stage.
