The term was introduced in 2015 by Curtis Marean as "extremely cooperative behavior with unrelated individuals, often for the benefit of others or society without expectation of payoff". [1] Although originating from an evolutionary anthropological perspective, hyperprosociality has been utilized in modern pedagogy and psychology .
Homo reciprocans, or reciprocating human, is the concept in some economic theories of humans as cooperative actors who are motivated by improving their environment through positive reciprocity (rewarding other individuals) or negative reciprocity (punishing other individuals), even in situations without foreseeable benefit for themselves.
As a social construct, reciprocity means that in response to friendly actions, people are generally nicer and more cooperative. This construct is reinforced in society by fostering an expectation of mutual exchange. While the norm is not an innate quality in human beings, it is learned and cemented through repeated social interaction.
Some examples of these human universals are abstract thought, planning, trade, cooperative labor, body decoration, and the control and use of fire. Along with these traits, humans possess much reliance on social learning. [12] [13] This cumulative cultural change or cultural "ratchet" separates human culture from social learning in animals.
Under this idea, selfishness would be expected to develop as a dominant behavior. Unlike cooperative models that link sharing to hunting, tolerated theft links sharing to arrival of any food package (either hunted or scavenged). Cooperative and reciprocal models, according to Jones, could not explain how food-sharing initially developed in ...
Edward O. Wilson called humans eusocial apes, arguing for similarities to ants, and observing that early hominins cooperated to rear their children while other members of the same group hunted and foraged. [46] Wilson and others argued that through cooperation and teamwork, ants and humans form superorganisms.
The sigmoidal shape of hemoglobin's oxygen-dissociation curve results from cooperative binding of oxygen to hemoglobin. An example of positive cooperativity is the binding of oxygen to hemoglobin. One oxygen molecule can bind to the ferrous iron of a heme molecule in each of the four chains of a hemoglobin molecule.
The concept of "reciprocal altruism", as introduced by Trivers, suggests that altruism, defined as an act of helping another individual while incurring some cost for this act, could have evolved since it might be beneficial to incur this cost if there is a chance of being in a reverse situation where the individual who was helped before may perform an altruistic act towards the individual who ...
