“…This result might be related to capuchin monkeys' life history, characterized by an extended period of infant dependency in comparison to other haplorrhines except for apes (Fragaszy et al, 2004). In this period, the infant is still dependent from the mother for nursing and carrying (Fragaszy et al, 1991;Verderane, 2005) and spend around 60% of the time in proximity with her (in less than 10m - Verderane & Izar, 2019). Further longitudinal studies assessing later life stages of infant capuchins might help to elucidate whether FF varies with age as seen in other NHP or is particularly important to this primate.…”

“…Weaning ages in Sapajus spp. occur at 15.5 months for nursing and at 12.7 months for carrying (Verderane & Izar, 2019). Indeed, all female infants from our sample were still nursed and carried by their mother at the end of the 12th months.…”

“…During the first three developmental points, infants are completely dependent on their mothers for nurse and locomotion, but the first contact breaks usually occur during this period (Verderane, 2005). As early as the sixth month, capuchin infants already spend a great amount of time apart from their mothers and tend to be responsible for maintaining contact between the dyad (Verderane, 2005;Verderane & Izar, 2019). At the 12th month, infants are still transported and nursed, but they spend more time apart from their mothers than in contact (Byrne & Suomi, 1995;MacKinnon, 2013;Verderane & Izar, 2019).…”

“…Due the importance of facial displays for communication (e.g., Carosi & Visalberghi, 2002;De Marco & Visalberghi, 2007), capuchins monkeys can be good models for investigating patterns and function of mother-infant FF early in life. Besides, as humans and pongids, capuchins have an extensive and intimate maternal care, both in captivity (Fragaszy, Baer, & Adams-Curtis, 1991) and in semi free ranging groups (Verderane, 2005), as well as in wild populations (Verderane & Izar, 2014, 2019. The infancy is prolonged until the second year of life and in the first year, the physical contact and proximity between mother and infants decrease gradually, as well as nursing and transportation (Verderane & Izar, 2019).…”

If FF regulate the physical contact between mothers and female infants of capuchin monkeys, we first expected that frequency of FF would (a) increase with infants' age (due to a decrease in physical contact); and/ or (b) in the absence of physical contact between the dyad throughout the first year of life.…”

Face-to-face interactions (FF) are an universal system of human parenting behavior (Keller, 2007) and one of the channels of early affective communication between mothers and their babies (Fogel, Messinger, Dickson, & Hsu, 1999; Tronick, 1989). From birth to childhood, mother and infant engage in FF through mutual gaze that are often preceded and accompanied by exaggerated particular patterns of crying, and facial expressions, kiss, and play (Fogel et al., 1999), that attract each other's attention and enhance the mutual engagement (Seidl de Moura et al., 2004). According to Beebe et al. (2018), FF communication is a dyadic system in which both partners contribute to exchange through a bidirectional co-regulation. There is evidence that these interactions influence the infant physiological

Animal personality is defined as consistent individual differences across time and situations, but little is known about how or when those differences are established during development. Likewise, several studies described the personality structure of adult capuchin monkeys, without assessing the ontogeny of these personality traits. We analyzed the behavioral repertoire of 12 wild infants (9 males, 3 females) yellowbreasted capuchin monkeys (Sapajus xanthosternos), in Una Biological Reserve (Bahia, Brazil). Each infant was observed and filmed weekly from birth until 36 months, through daily focal sampling. We analyzed the behavior of each individual in 10 developmental points. By means of component reduction (principal component analysis), we obtained four behavioral traits: Sociability, Anxiety, Openness, and Activity. We investigated whether there were developmental effects on those traits by fitting regression models for the effect of time on behavioral traits, controlling for monkey identity, sex, and cohort. Sociability (decreasing) and Anxiety (increasing) changed significantly along development. By means of repeatability analysis, we did not find intra-individual consistency across time in those traits, so we cannot discriminate stable personality traits in early ontogeny. Our results show that the personality structure of capuchin monkeys is not established during early development, in agreement with the literature on human personality.

Sociability is a fundamental trait that social animals need to survive and reproduce in societies. Sociability predicts how an individual can consistently interact with its conspecifics across time and situations. By studying capuchin monkeys (Sapajus libidinosus), a neotropical primate with complex social behavior and high cognitive capacity, our research aims to analyze the development of the social axis of personality of immature individuals, from birth to the third year of life. We studied wild monkeys belonging to a group with infants, juveniles, and adults of both sexes that inhabits northeastern Brazil. We analyzed the behavior of 12 immature capuchins (6 males and 6 females) in 94 h of videos recorded weekly from birth until 36 months, through daily focal sampling. We verified whether there was intraindividual consistency throughout development by fitting regression models for the effect of age on initiating affiliative social behaviors, controlling for monkey identity and sex. Our results indicate that the individuals of this study exhibit high variation in the initiation of behaviors at the beginning of infancy; there was low repeatability and high intra‐individual variation during the first 3 years of life of these individuals, indicating that the social personality is not consolidated in this period. Immature females were more sociable than immature males. Therefore, differences in sociability in early life of bearded capuchin monkeys are best explained by sex rather than personality. We suggest that the high initial behavioral variation in the social axis of personality allows for plasticity influenced by the environment throughout development. The high sociability of females in infancy may be related to female philopatry and their high sociability in adulthood.
