The ACBA methodology uses GP as hypothesis generation and testing of human behavior. It generates programs by combining symbols encoding relevant task information and certain operators, given some behavior instance of interest. A program’s fitness is measured according to how consistent its output is in relation to the outcomes of the exhibited behavior. By using standard GP techniques, ACBA progressively generates candidates attaining higher and higher degrees of fitness. When GP finishes, the most fit programs are chosen as hypotheses of, i.e., possible solutions for, the underlying structure of the observed behavior.
The work in [bibcite key=sequeira2018cogsci] studies the influence of personality traits in negotiation by using ACBA. The goal is to study the behavior exhibited by individual during a multi-level, multi-issue, sequential bargaining task against an artificial agent. The study focuses on the influence of the personality traits of social-value orientation (SVO) and Machiavellianism (Mach). The results show that ACBA is able to identify differences in the outcomes of programs emerging from GP that are consistent with the influences that different SVO and Mach profiles have in human negotiation behavior, as informed by specialized literature in negotiation behavior.
