- Learning and reciprocity in coal tits playing the Prisoner’s Dilemma game Luis M Bautista Beatriz Martín Psicología Auto toma y daca reciprocidad Periparus ater juegos de forrajeo Foraging tests of the Iterated Prisoner’s Dilemma (IPD) show animals defect, contrary to evolutionary models that predict cooperative animals will prevail and spread in populations. This contradiction could be due to IPD rules that could be too challenging to understand for most animals. We explored this hypothesis relaxing the payoff matrix of the IPD (T>R>P>S=0) to a weak payoff-matrix (T=R>P=S>0) and tested it with coal tits, which did not play one another; rather, each one played against a computer programmed to deliver food pellets according to the ‘Tit for Tat’ strategy. Despite the IPD was programmed with a weak payoff matrix, coal tits preferences to defect increased a 10% when playing the Game condition as compared to a previous Control condition. In the Control condition they foraged at random (48±11%) between two pellet dispensers that delivered food rewards at the same rate, while in the Game condition they increased the preference towards the defection option (58±10%). A sequential (trial by trial) analysis showed that these small birds defected regularly and cooperated at random. While the small preference (10%) for defection observed in a weak version of the IPD suggests IPD standard experiments may be exceedingly stringent for research on animal reciprocity, the absence of cooperation even in a weak IPD demands further research with our reciprocity experimental design and with other species to shed light on the underlying learning processes. 2018 artículo científico 0185-4534 https://www.redalyc.org/articulo.oa?id=59367993005 https://www.redalyc.org/journal/593/59367993005/ https://www.redalyc.org/journal/593/59367993005/html/ https://www.redalyc.org/journal/593/59367993005/59367993005.epub https://www.redalyc.org/journal/593/59367993005/movil https://doi.org/10.5514/rmac.v44.i2.6883 en http://www.redalyc.org/revista.oa?id=593 Revista Mexicana de Análisis de la Conducta application/pdf Sociedad Mexicana de Análisis de la Conducta Revista Mexicana de Análisis de la Conducta (México) Num.2 Vol.44
