Abstract

The current literature reports that oral language development is not a realistic goal for autistic cochlear implant users (ACI). This is curious, due to the general success of cochlear implants and the fact that many autistic individuals develop strong spoken language skills. Therefore, this study aimed to examine clinician and caregiver insights into spoken language development in the ACI population with the aim of elucidating the factors that influence the poor outcomes reported in the literature. We predicted that cochlear implant function would not be the limiting factor in ACI language development, but that device use and sensory atypicalities might have significant impacts. Participants were two speech-language pathologists (SLPs), six audiologists (AuDs), and one dually certified SLP/AuD. Additionally, six mothers and their ACI children participated in the study. All participants, excepting one ACI parent, took a survey and then participated in a 30–60-minute interview about their experience either caring for or working with ACIs and their insights into their language development. We also collected language samples in ACI participants. Quantitative analysis included computing descriptive and inferential statistics, where appropriate, concerning language abilities, sensory processing, anxiety, and survey responses regarding factors associated with cochlear implant (CI) use. We also engaged in qualitative thematic analysis of caregiver and clinician interviews. Quantitative and qualitative results were then integrated to triangulate findings. In important ways, our results are inconsistent with current literature concerning ACIs. For instance, caregiver and clinician statements, as well as quantitative results suggested that it was very possible for ACIs to develop spoken language, when given the right conditions. Qualitative themes that shed light on the factors important to positive language-related outcomes in ACIs included: a) finding (and advocating for) access to care; b) sensory processing difficulties; c) differentiating between autism and hearing loss, and the spectra of both conditions. One specific and novel finding showed that sensory profiles—especially sensory seeking versus sensory averse—may have a significant impact on a child’s oral language development following cochlear implantation and should be considered when counseling families on possible outcomes. These findings provide new insight into and concrete future directions for supporting the ACI population.
