The traditional model of child psychology in relation to parents is called, "Classical Attachment" in which the child has a strong attachment to one figure (the mother). In alloparenting communities, attachment theory suggest that the same sort of bond is shared between the child and multiple community members.[32] This has potential advantages for the child and the parents. The child has a diversified network of caregivers which can provide intimate emotional support.[33] The parent's cost of child rearing goes down as well as the emotional cost and cost of tangible resources. According to The US National Library of Medicine, alloparenting has proven to activate portions of the brain that are correlated with decreasing stress levels.[34] Different societies take care of their young differently. It often boils down to economic activities. For example, take two locations, location A and location B. Location A is a large city where life is hectic. Children are usually raised here according to classical attachment. On the other hand, location B is in the countryside where people get to see each other more often. Location B is essentially an alloparenting community. In which location parents would incur less cost for child rearing, location A or location B?

Some processes in the body are regulated by positive feedback. Positive feedback is when a response to an event increases the likelihood of the event to continue. An example of positive feedback is milk production in nursing mothers. As the baby drinks her mother's milk, the hormone prolactin, a chemical signal, is released. The more the baby suckles, the more prolactin is released, which causes more milk to be produced. Other examples of positive feedback include contractions during childbirth. When constrictions in the uterus push a baby into the birth canal, additional contractions occur. John is a doctor at the children's hospital. He had two different cases to investigate, case A and case B. In case case A, a baby continued to suckle mother's milk. But in case B, a baby stopped suckling mother's milk. He had to determine the different effects these two cases were causing. In case A would less or more milk be produced than in case B?
