12、 moral discriminations about harmful actions committed against themselves or others has been the focus of recent research into the moral development of children.Until recently,(5)child psychologists supported pioneer developmentalist Jean.Piaget in his hypothesis that because of their immaturity,chi

14、t stage of moral development,which is char-acterized by moral absolutism(rules made by authorities must be obeyed)and imminent justice(if rules are broken,(15)punishment will be meted out)。Until young children mature,their moral judgments are based entirely on the effect rather than the cause of a t
15、ransgression.However,in recent research,Keasey found that six-year-old children not only distinguish between accidental and intentional harm,but(20)also judge intentional harm as naughtier,regardless of the amount of damage produced.Both of these findings seem to indicate that children,at an earlier
16、 age than Piaget claimed,advance into the second stage of moral develop-ment,moral autonomy,in which they accept social rules(25)but view them as more arbitrary than do children in the first stage.Keaseys research raises two key questions for develop-mental psychologists about children under age sev
