When administered to 34 infants with handicaps, Bayley Scale mental age scores were an average of 2.1 months higher than Estimated Developmental Ages (EDA's) calculated from the Uzgiris and Hunt Scales. The EDA's were significantly and positively related to Bayley mental age, and sensorimotor play emerged as the best single correlate. (Author/JDD)
