This report describes the development of a new procedure for assessing neurodevelopmental delay in young children. The Primitive Reflex and Postural Adjustment Assessment procedure is designed to measure degrees of occurrence of remnants of primitive reflexes and immature postural adjustment. Preliminary findings show that the Primitive Reflex and Postural Adjustment Assessment procedure can successfully identify degrees of neurodevelopmental delay in young children, and that the procedure differentiates normal children from mentally retarded and emotionally disturbed children. Additional work is needed to assess the validity and reliability of this procedure.
