Cooperation in children, siblings and not biologically related, exposed to reciprocal contingencies. Cooperación en niños, hermanos y no relacionados biológicamente, expuestos a contingencias recíprocas.

Abstract

The objective of this investigation was to establish if exist differences in the degree of cooperation, between children biologically related and not related exposed to reciprocal contingencies. The total of subjects selected for this investigation was of seven pairs of children brothers and seven pairs of children nonrelated biologically, with ages between the ten and fourteen years, of a school of the city of Bogota. For the analysis of data between groups was used the statistical test, test of student of comparison of mead for independent samples, the data indicated that there are not differences statistically significant between brothers and not related biologically; as for the condition of cooperation as for the condition of noncooperation. Otherwise, when doing a comparison intragroups by means of a simple ANOVA, significant differences between the conditions, cooperation noncooperation were obtained, as for the brothers as for not related: F (3,52) =16,292, P< 0.05, for the condition for maximizing the gains; F (3,52) = 25.564, P<0.05, for the condition for diminishing the losses. These results suggest that variables important in a situation of choice between cooperating and not cooperating are the reciprocal contingencies, than the variables of genetic relation.
