The purpose of this study was to investigate the relationship of reflection-impulsivity, verbal comprehension, and achievement motivation to level of moral development. Reflection-impulsivity is a cognitive style; verbal comprehension a measurement of intelligence. A random sample of 40 boys and 40 girls was selected from the senior classes of two Catholic high schools and a battery of tests was administered to the sample. Results of the analysis showed that the total error measure of reflection-impulsivity and verbal comprehension correlated significantly with the level of moral development. However, only the error measure of reflection-impulsivity was found to be a predictor variable of level of moral development. (Author/ND)
