This study explored possible associations of social maturity, executive
function (EF), self-efficacy, and communication variables among deaf university
students, both cochlear implant (CI) users and nonusers. Previous studies have
demonstrated differences between deaf and hearing children and young adults in
EF and EF-related social and cognitive functioning. EF differences also have
been demonstrated between hearing children and deaf children who use CIs.
Long-term influences of cochlear implantation in the social domain largely have
not been explored, but were examined in the present study in terms of social
maturity, as it might be related to EF and communication variables. Replicating
and extending recent findings, social maturity was found to be related to
somewhat different aspects of EF in CI users, deaf nonusers, and hearing
students, but unrelated to hearing status, CI use, or deaf students’ use
of sign language versus spoken language. Self-efficacy proved a predictor of
self-reported socially mature and immature behaviours for all groups.
Individuals’ beliefs about their parents’ views of such behaviours
was a potent predictor of behaviours for deaf CI users and those deaf students
who reported sign language as their best form of communication.
