Here we report results of a lab-in-the-field experiment with people of different ages in a social dilemma. We find that the average amount of cooperativeness is independent of age except for the elderly, who cooperate more, and a behavioural transition from reciprocal, but more volatile behaviour to more persistent actions towards the end of adolescence. Although all ages react to the cooperation received in the previous round, young teenagers mostly respond to what they see in their neighbourhood regardless of their previous actions. Decisions then become more predictable through midlife, when the act of cooperating or not is more likely to be repeated. Our results show that mechanisms such as reciprocity, which is based on reacting to previous actions, may promote cooperation in general, but its influence can be hindered by the fluctuating behaviour in the case of children. info:eu-repo/grantAgreement/ES/MINECO/PRODIEVO info:eu-repo/grantAgreement/ES/MINECO/FIS2011-25167 info:eu-repo/grantAgreement/ES/MINECO/FIS2009-09689 info:eu-repo/grantAgreement/EC/FP7/317532/EU/Foundational Research on MULTIlevel comPLEX networks and systems/MULTIPLEX info:eu-repo/grantAgreement/ES/DGA/FENOL-GROUP info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 11.47 2014 MULTIDISCIPLINARY SCIENCES 3 / 57 = 0.053 2014 Q1 T1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0002-9769-8796 Gracia-Lázaro, Carlos Universidad de Zaragoza Perelló, Josep (orcid)0000-0002-0895-1893 Moreno, Yamir Universidad de Zaragoza Sánchez, Ángel 2004 405 Universidad de Zaragoza Dpto.
