Exploration of Cooperation during an Asymmetric IteratedPrisoner's Dilemma Game. Master of Science (Behavior Analysis), August 2020, 61 pp., 12 figures, 2 appendices, references, 58 titles.Researchers investigated how the contingent delivery of a cultural consequence on target culturants in an asymmetric iterated prisoner's dilemma game (IPDG) affected players' choices.The asymmetric IPDG creates an analogue to income disparities created by wage gaps and other cultural practices that create wealth inequalities between different members of the population and allows researchers to explore how these inequalities affect cooperation between players. Six undergraduate students divided into three dyads participated in an ABABCDCD reversal design.An asymmetric IPDG was arranged in Condition A and C such that one player received a greater number of points regardless of the second participants' selections -analogue to contingencies that produce income inequalities from wage gaps. In Condition B and D, a metacontingency was arranged such that delivery of a cultural consequence (CC; bonus points equally distributed among the dyad) was contingent on the oscillating production of target aggregate products (AP) across two consecutive cycles. When participants' coordinated responding and contacted the target AP→ CC relation, the wage gap was reduced. However, individual contingencies are in direct competition for the "wealthier" player, reducing the probability of cooperative responding.Results showed the CC selected certain oscillations between target APs resulting in a decrease of a point disparity between the players while also establishing equal points between the players during certain conditions.

A Análise do Comportamento tem demonstrado interesse em questões sociais com o propósito de intervir em problemas como o racismo. Propõe-se, neste ensaio, uma reflexão teórica sobre os efeitos do racismo na construção do self de pessoas negras, com o foco em microagressões, em especial a piada racista. Para tanto, apresentamos como as microagressões raciais podem ser compreendidas a partir da noção de quadros relacionais, e seu impacto no aprendizado de relações simbólicas. Em seguida, partimos dessas elaborações teóricas para discutir as funções das piadas racistas e suas consequências para a construção do selfde pessoas negras. Concluímos que as piadas racistas, como parte das relações aprendidas, interferem na formação do self se referindo a pessoas negras como algo inferior e digno de menosprezo em vários aspectos.
