Influence of Piaget

• Kohlberg built on theories of Swiss-born Piaget, who believed children develop intellectually in stages from birth through adulthood, with a shift in moral thinking near age 11.
  
  By focusing on morality rather than cognitive development, Kohlberg forged new paths in his field.
  
  

Heinz Dilemma

• Kohlberg tested children's moral thinking by posing the Heinz Dilemma---should a man who could not afford a druggist's medicine steal a cancer drug to save his dying wife? Analyzing the children's responses, Kohlberg developed his six stages of moral development.
  
  His 1958 doctoral dissertation study, surveying 72 boys of various ages from Chicago, expanded in scope in later tests to substantiate his initial theory.
