Abstract: The Musical-Perception Assessment of Cognitive Development (M-PACD) developed by Rider (1981) was applied to twenty mentally retarded students. Tasks on the M-PACD employed Piagetian concepts and were develop- mentally ranked from least to most difficult. The developmental order of the present study was compared to the developmental order of a previous study that used nonhandicapped students. A Spearman Rank-Order Correlation identified a significant relationship between the developmental order manifested by men- tally retarded and nonhandicapped students. A Pearson Product-Moment Correla- tion Test identified no significant relationship between the number of tasks passed by each student and his or her intelligence quotient. The Pearson Test however, identified a significant correlation between the number of tasks mastered by each student and his or her mental age and chronological age. Results indicate that the M-PACD is a valid developmental ordering instrument of musical perception tasks, and could be used as a tool for assessing cognitive development.
