Recently, there been a number of studies indicating that mothers’ input shapes vocal development in infant marmosets beyond what is expected from simple maturation (Takahashi, Liao & Ghazanfar 2018). These results have yielded a preliminary primate model of how mother-infant interaction shapes “speech” development. Independent of this, our laboratory at Vanderbilt University Medical School has been studying how clinician-patient interaction wherein a child's immature speech vocalization is immediately followed by a more advanced clinician (or parent) model leads to improvements in speech production in these patients. This presentation will include a review of the recent mother-infant marmoset results and a description of results from children with speech disorders, Down syndrome, and autism parallel the primate findings (Yoder, Camarata & Woynaroski, 2016). In addition, potential next steps in discovery will be suggested and discussed.
