aim
to investigate developmental moral reasoning throughout adolescence and early adulthood. A secondary aim was to assess the extent to which these changed hold true in a range of cultural contexts
backround
sample/participants
75 boys from Chicago were followed for 12 years at 3-year intervals
at the start the boys were ages 10-16 and they (58) were followed to ages 22-28
boys in great britain, canada, taiwan, mexico and turkey were also studied
method
longitudinal research using self-report
procedure
results
Based on their responses to moral dilemmas moral development was divided into three broad levels of morality each of which contains two stages. Each stage is a distinct moral philosophy. There were differences in pace but not sequence of development across nationally, social class and religion
conclusions
There is a universal sequence of stages to moral development. Children in the same stage of moral development tend to reason in the same way
