An empirical test of the central concept and treatment efficacy of the Doman-Delacato rationale was implemented by investigating the influence of a program based on the theory of neurological organization on the reading development of retarded readers. The study employed a traditional control group and a nonspecific program, thought to simulate the placebo effect. The results failed to confirm the validity of the rationale— suggesting that verifiable, empirical evidence from carefully controlled studies is needed if the rationale is to be taken seriously by the scientific community.
