An intersubjective developmental perspective on interactions between deaf and hearing mothers and their deaf infants.

Most research into interactions between mothers and their infants with hearing impairments focuses on mothers' and infants' behaviors separately, speculating about the interplay among these behaviors and their effects on child development. In the present article, an intersubjective developmental theory focusing on the development of the "interworld" between deaf and hearing mothers and their deaf infants is used to integrate and interpret the seemingly incoherent research on early mother-deaf child interaction. Inspired by Stern's work (e.g., Stern, 1985), the intersubjective developmental theory distinguishes four stages in the development of intersubjectivity: emerging (birth-2 months), physical (2-8 months), existential (8-13 months), and symbolic (13 months and older), each characterized by a different type of mother-infant interaction. The integration of research findings on early mother-deaf child interaction into these four developmental stages offers new perspectives that can advance research and resolve certain early-intervention issues.
