“…Since younger mothers would have the most to lose in future reproductive potential investing too much in their current infant (Pianka and Parker 1975), it could be expected that they would be more rejecting and less protective than older mothers. However, results from several studies in both rhesus and Japanese macaques oppose this hypothesis, since it has been found that primiparous mothers were more protective and multiparous mothers more rejecting (Hiraiwa 1981, Hooley andSimpson 1981;Berman 1984;Schino et al 1995).…”

This research assessed mother-infant relationships in rhesus and Japanese macaques living in analogous captive social groups, and monitored changes in the levels of excreted estrogen metabolites during the peripartum period. Each mother-infant pair was focally observed 3 h per week during the first 12 weeks of life of newborns. Fecal samples were collected twice a week from each mother, starting 4 weeks before delivery and ending 4 weeks after delivery. Infant-directed behaviors appeared to be consistently less protective/controlling and more rejecting in rhesus macaques than in Japanese macaques. Estrogen metabolite levels during the perinatal period were, on average, 3-fold higher in Japanese macaques and showed a sharp increase during the last weeks of pregnancy only in the Japanese macaque group. Considering the ecological and behavioral similarities between Japanese and rhesus macaques, the divergence between the two species in the onset and maintenance of maternal behavior was unexpected. This was possibly linked to the difference in the overall body size and life history, and to the striking divergence in estrogen metabolite variation during the peripartum period. Group size, social relationships, and average age of individuals in the two captive groups were not clearly involved in the recorded differences in maternal behavior.Keywords Japanese macaque AE Rhesus macaque AE Maternal behavior AE Estrogen metabolites AE Enzyme immunoassays Primates (2003) 44: 91-98

“…Moreover, although mothers largely maintain their maternal style across different offspring 2 , 10 , 22 , they can also adjust it to the specific needs and developmental phase of the offspring 23 . Mothers, for instance, are usually more protective towards younger offspring 24 – 26 . In contrast, rejecting behaviour appears to peak between the first and the second year of offspring’s development, at least in macaques 18 , 25 , 27 , when mothers start resuming their mating activities 28 – 30 .…”

Comparative perspectives are crucial in the study of human development, yet longitudinal comparisons of humans and other primates are still relatively uncommon. Here, we combined theoretical frameworks from cross-cultural and comparative psychology, to study maternal style in 10 mother–infant pairs of German urban humans (Homo sapiens) and 10 mother–infant pairs of captive chimpanzees (Pan troglodytes), during the first year of infants’ development. We conducted focal observations of different behaviours (i.e. nursing, carrying, body contact, touching, grooming, restraining, approaching, leaving, rejection, aggression, mutual gaze, object stimulation), during natural interactions. Analyses revealed a more distal maternal style in WEIRD humans than in captive chimpanzees, with different behaviours being generally more common in one of the two species throughout development. For other behaviours (i.e. nursing), developmental trajectories differed between WEIRD humans and captive chimpanzees, although differences generally decreased through infants’ development. Overall, our study confirms functional approaches as a valid tool for comparative longitudinal studies.

“…However, mothers adjust their distribution of protective and rejective behaviors according to the offspring's developmental stage. For instance, primate mothers usually show more protectiveness toward younger offspring (e.g., Hernández-Lloreda & Colmenares, 2005;Negayama, 1981;Schino et al, 1993). Also, among macaques, rejection of offspring often peaks between 4-6 months (Maestripieri, 2002;Negayama, 1981) and 1-2 years of age (Kulik et al, 2016) -when mothers are more likely to resume their mating activities (Berman et al, 1993;Gomendio, 1991;Worlein et al, 1988)-and slowly decreases thereafter.…”

Female primates represent the most important social partner for their developing offspring. However, mothers may strongly differ in the way they relate to their offspring (e.g., in terms of two different dimensions: protectiveness and rejection). In this study, we aimed to assess how dominance style predicts (i) changes in maternal behavior through offspring development, and (ii) the link between maternal behavior and offspring behavior. We conducted behavioral observations on 34 free‐ranging immatures of two species of macaques with different dominance styles: less tolerant Japanese macaques (JM; Macaca fuscata) and more tolerant moor macaques (MM; Macaca maura). Our results showed that maternal behavior differed between JM and MM: maternal proximity and grooming decreased through offspring development more quickly in MM than in JM, whereas maternal rejection and aggression, which were generally more frequent in JM, decreased with offspring age similarly in both species. In contrast, maternal restraint of offspring decreased similarly with offspring age in both species. Furthermore, dominance style was differentially associated with the link between maternal and offspring behavior: in MM only, maternal grooming predicted an increase of the probability that offspring interacted with partners other than their mothers and engaged in solitary play, whereas maternal rejection predicted a decrease in the occurrence of solitary play. Overall, these results suggest interspecific variation in maternal behavior during offspring's first years of life, and point to the possibility that these differences may have an important role in shaping their behavioral development.
