Many researchers pointed out that behavior-analytic principles can promote our society to be fair and just (Biglan, 2015; Levy et al., 2021; Skinner, 1953). The promotion of cultural awareness, competence, sensitivity, and humility and minimizing cultural biases and prejudice give us promising outcome to make world a better place. This notion has been supported by scholarly recommendations, recent concepts and principles, and a growing body of empirical research. This presentation includes the analysis of the acquisition of cultural biases and cultural humility. Cultural biases can be conceptualized through respondent conditioning (i.e., stimulus-stimulus pairing; Matusda et al., 2020) and operant conditioning (e.g., manipulation of motivating operations [MOs], stimulus control, consequence, and verbal behavior [e.g., rules]; Critchfield et al., 2018). Moreover, this presentation offers the summaries of how cultural humility and cultural sensitivity can be promoted in applied settings (workplace and fieldwork supervision). Although several scholars recommended many strategies for promoting cultural sensitivity and cultural competence in workplace and fieldwork supervision, empirical support is still needed to offer the most effective outcomes (Matsuda et al., 2020; Levy et al., 2021). Future studies may evaluate the long-term effectiveness of existing interventions.
