Peter MacNeilage and Barbara Davis have promoted a longstanding companion

program for grounding developmentally-then phylogenetically-speech motor

control within the Frame/Content Theory (FCT, MacNeilage, 1998). Like many

other researchers who discussed and supported FCT with data from their own

field and ambient language, we are deeply indebted to this impetus for French

baby studies and potential for links with primatology (Abry & Schwartz, J. L.,

2004, Abry et al., 2004).
