This chapter fills in the French situation and complements chapter 5’s questioning about the linguistic achievement of homesigners by asking whether homesigns are sufficient to help the child develop a mature cognition. Several studies on theory of mind in deaf children and adults suggest that language-communication (not just gestural communication) is a critical variable in proper cognitive development. Additionally, the age of ten appears to be a significant time — an earlier critical period than Wood’s studies found. These findings, while not constant, are relatively persistent, regardless of whether children eventually receive hearing aids or cochlear implants (where no difference between the two types of aids is noted).
