This extensive volume is the major report of results from studies of speech, language, and hearing conducted as part of the National Collaborative Perinatal Project. The research was performed over a ten-year period ending in 1974, and included 27,558 children drawn from the 55,908 pregnancies originally registered at the start of the collaborative study.
