Our aim was to show that jealousy may be observed in infants already during the first year of life. When infants perceive a threat to their exclusive relationships with caregivers, their reactions are associated with activation of negative emotion response systems, mediated by the HPA stress axis. Basic emotion regulation processes, as well as oxytocin and dopamine restore homeostasis by shutting down the stress response. We have further shown that infants may also be excluded by peers with whom they have not yet established exclusive relationships. We have proposed that infants experience negative emotionality and stress associated with the loss of social connections, but suppress these emotions due to their insecurity with the social situation. This results in a passive aversive reaction at the neural and behavioral level. Thus, infants have the necessary neural substrate and socio-cognitive abilities to conceptualize different social exclusion situations and react appropriately.
