Moral and cognitive development of moderately retarded, mildly retarded, and nonretarded individuals.

The relationships of moral maturity, cognitive reasoning, MA, and CA were investigated with three IQ groups. The subjects were 20 moderately retarded, 20 mildly retarded, and 20 nonretarded individuals matched for MA. The findings indicated that moderately retarded individuals are at lower levels of cognitive reasoning and moral maturity than MA-matched mildly retarded and nonretarded individuals. The findings also indicated a stronger relationship between moral maturity and cognitive reasoning than between MA and moral maturity or MA and cognitive reasoning. The findings were discussed in terms of the positions of Kohlberg and Gilligan (1971) and Taylor and Achenback (1975).
