Moral reasoning of Piagetian-matched retarded and nonretarded children and adolescents.
The moral reasoning of four IQ/etiology groups was investigated: 19 organically abnormal moderately retarded, 19 organically abnormal mildly retarded, 19 mildly retarded due to psychosocial disadvantage, and 19 nonretarded individuals. In each group 12 Ss were preoperational and seven concrete operational. Moral reasoning was assessed by an instrument using moral dilemmas based on Kohlberg's procedures. The Slosson Intelligence Test was used to determine the IQs and mental ages of each S. Piagetian stage was determined with the standard conservation of number tasks. The findings indicated no overall significant differences between the mildly retarded and the nonretarded Ss or between the mildly retarded and the moderately retarded Ss, but differences were found between the moderately retarded and the nonretarded Ss. A significant interaction was found between the two independent variables, IQ/etiology and cognitive level. The results were discussed as supporting Zigler's development position and as damaging to Kohlberg's position.
