Kohlberg proposed that various cultural, social and educational factors may influence moral reasoning. As far as the authors know, participants in previous studies of moral reasoning have been, largely, educated persons, irrespective of their culture. Two studies on moral reasoning were conducted in a Mexican-United States border city. The first study found that even some unschooled, non-literate adults reason at a high stage (formal operations, Moral 3/4). Exposure to different cultural and organizational contexts, in addition to assumption of leadership roles, was associated with such reasoning. Likewise, the second study found that high school students who were identified as leaders, especially those with cross-cultural contact and those who were of high socio-economic status, reasoned at higher stages than those who were not. Overall, stage of reasoning increased with age.Cross-cultural studies have consistently demonstrated that higher reasoning stages among adolescents and adults positively correlate with the amount of formal education a person has (Harkness et al.stage development proceeds throughout childhood and adulthood (Dawson-Tunik et al., 2005). Although researchers have confirmed the invariance of the stage acquisition sequence among non-literate (non-educated) participants from other
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
