The present research was designed to investigate the effect of intelligence, birth-order and age of the children on their moral judgement. The design of the study was 2 x 2 x 2 factorial with two levels of intelligence (higher and lower), two birth-orders (First born and last born children in the family) and two levels of age (6-7 years and 10-11 years). The main effects of intelligence, birth-order and age were found to be significant. None of the interactions were found to be significant.
