Prelinguistic Vocal Development in Infants with Typical Hearing and Infants with Severe-to-Profound Hearing Loss
Peer reviewed Peer reviewed
Direct linkDirect link
Iyer, Suneeti Nathani; Oller, D. Kimbrough – Volta Review, 2008
Delays in the onset of canonical babbling with hearing loss are extensively documented. Relatively little is known about other aspects of prelinguistic vocal development and hearing loss. Eight infants with typical hearing and eight with severe-to-profound hearing loss were matched with regard to a significant vocal development milestone, the…

Iyer, Suneeti Nathani; Oller, D. Kimbrough – Clinical Linguistics & Phonetics, 2008
Little research has been conducted on the development of suprasegmental characteristics of vocalizations in typically developing infants (TDI) and the role of audition in the development of these characteristics. The purpose of the present study was to examine the longitudinal development of fundamental frequency (F[subscript 0]) in eight TDI and…

The Role of Audition in Infant Babbling.
Peer reviewed Peer reviewed
Oller, D. Kimbrough; Eilers, Rebecca E. – Child Development, 1988
A comparison of vocal development in deaf and hearing infants indicates that well-formed syllable production is established in the first 10 months of life by hearing infants but not by deaf infants, suggesting that audition plays an important role in vocal development. (PCB)

Babbling of Prelinguistic Mentally Retarded Children.
Peer reviewed Peer reviewed
Oller, D. Kimbrough; Seibert, Jeffrey M. – American Journal of Mental Retardation, 1988
Comparison of canonical (well-formed syllabic) babbling in 36 prelinguistic retarded children (17 to 62 months of age) with nonretarded children indicated a low correlation between babbling and developmental age suggesting substantial independence between cognitive development and babbling among retarded children.

Late Onset Canonical Babbling: A Possible Early Marker of Abnormal Development.
Oller, D. Kimbrough; Eilers, Rebecca E.; Neal, A. Rebecca; Cobo-Lewis, Alan B. – American Journal on Mental Retardation, 1998
Onset of canonical babbling was investigated for 1,536 high-risk infants at about 10-months corrected age. Although delays were infrequent, they were often associated with genetic, neurological, anatomical, and/or physiological abnormalities. Over half the cases of late canonical babbling, at the time of discovery, were not associated with prior…
