These materials concern research conducted and supervised by the Hardys. Research projects include The Collaborative Perinatal Study and ancillary research studies, including studies of hearing and communication disorders in children with rubella; studies of the effects of delayed auditory feedback on infants’ vocalization; hearing loss and language acquisition in very young children; and audiometric testing.
Johns Hopkins University, in collaboration with the National Institute of Neurological Diseases and Stroke, NINDB, participated, along with thirteen other medical institutions, in a national study of 60,000 pregnancies and resultant children up through eight years of age. The study’s purpose was to investigate the relationships of factors in pregnancy to morbidity and mortality of children. Between 1958 and 1964, the Hearing and Speech Center and Department of Otolaryngology at Johns Hopkins participated in research on neurological and sensory disorders of infancy and childhood. The Hopkins Collaborative Perinatal Study population was utilized for this research that included the study of the development of hearing in infancy and early childhood. This project included neonatal auditory screening and the development of a field screening hearing and language test for a 36-month check-point of the national study. The research resulted in an illustrative motion picture concerned with the development and measurement of hearing in infancy.
In the final years of the study, between 1963 and 1964, the Baltimore area was subject to an outbreak of rubella that affected many of the study participants. Children with congenital rubella were included in a follow-up study of communication disorders in children with rubella.
Sub-series materials include correspondence, data, forms, grant applications, notes, and papers describing research at Johns Hopkins including papers by Janet Hardy, Miriam and William Hardy, and Harriet Haskins.
Materials are arranged in several sub-sub-series, in alphabetical order by research study name or descriptive titles.
Sub-series 3.6 “Conferences, Symposia, and Workshops hosted or Co-hosted by The Johns Hopkins University” contains a program for a conference hosted at Hopkins in 1970 on the Collaborative Perinatal Project.
[Sub-sub-series 6.1.04] Delayed Language Development: Auditory Input Factors, A Study of the Auditory Input Recepter, Effector, and Control Factors Relative to Preschool-Age Children with Delayed Language and Speech. — 1961-1964; undated
Topics of key interest to the Hardys included among the files are audiometry -- EDR audiometry, SKR audiometry, and PGSR audiometry, and Dyslexia and other reading disorders affected or caused by hearing impairment, specifically as regarded the connection between learning disabilities and hearing disabilities. Research on the effects of congenital rubella was a research subject of particular importance to Miriam P. Hardy, who completed research on the subject alongside Dr. Janet Hardy. Many files pertain to screening, development, and evaluation, including screening methods of infants and children as well as language development, aphasia, and other language disorders.
Materials include bibliographies; newspaper and journal articles, monographs, papers, reports, reprints, and theses; charts and handouts used in teaching and publications; correspondence; medical evaluation forms, including screening examination forms; topical literature including informational pamphlets, booklets, and advertisements; and hand-written notes and notebooks. Files contain brief runs of two periodicals, Verbatim and Science.
Records are arranged in alphabetical order by subject.
