An evaluation of prelearning theory - which maintains that normative brain cell death prior to birth can be beneficially influenced by sensory imprinting - began in December 1986, providing progressive sonoral stimuli for a two-month fetus. These sequenced signals were adapted from the maternal blood pulse, as recorded by hydrophone in utero, thus conforming to the prenate's natural sonic environment; three hours of daily application lasted seven months, administered from a portable audiocassette player with transducers positioned on the abdomen. Following a July 1987 birth, developmental stages were assessed on the Clinical Linguistic and Auditory Milestone Scale (CLAMS) and other measurements, these preliminary data grounds for expanding the pilot study to additional gravidae. Project Prelearn's second phase neonates - including identical twins - performed comparably with the first advantaged infant; average receptive and expressive inventory scores at six months describe achievement in children one year older, ten months beyond the gifted level. Continued tracking utilizing control and comparative measures will test this initial determination. The study's background, rationale, protocols, and technical means are detailed, with outcomes statistically as well as visually presented; these results have inaugurated a controlled clinical trial employing a more rigorous methodology, external evaluations, and a substantially larger number of subjects.
