RESEARCH QUESTION
What are the primary factors influencing literacy
development in individuals with cochlear implants and/or
hearings aids?
![Page 3: Systematic review of the factors influencing literacy ...msjohnsonscienceclass.weebly.com/uploads/9/2/2/1/9221026/sample_ppt.pdfsystematic review of the factors influencing literacy](https://reader036.fdocuments.in/reader036/viewer/2022062603/5f155c7974fdd606d5419e82/html5/thumbnails/3.jpg)
BACKGROUND
• Deaf and Hard of Hearing (DHH)
• Cochlear Implant (CI)
• Hearing Aid (HA)
![Page 4: Systematic review of the factors influencing literacy ...msjohnsonscienceclass.weebly.com/uploads/9/2/2/1/9221026/sample_ppt.pdfsystematic review of the factors influencing literacy](https://reader036.fdocuments.in/reader036/viewer/2022062603/5f155c7974fdd606d5419e82/html5/thumbnails/4.jpg)
BACKGROUND
• DHH often fail to develop literacy
• Issue currently at field’s forefront
• Nittrourer et al. found early implantation important (2012)
• Castellanos et al. found preschool skills predictive (2014)

BACKGROUND
• Age of Initial Device Implementation
• User Compliancy
• Pre-school literacy intervention
![Page 6: Systematic review of the factors influencing literacy ...msjohnsonscienceclass.weebly.com/uploads/9/2/2/1/9221026/sample_ppt.pdfsystematic review of the factors influencing literacy](https://reader036.fdocuments.in/reader036/viewer/2022062603/5f155c7974fdd606d5419e82/html5/thumbnails/6.jpg)
REASONING
• Lack of comprehensive studies
• Accuracy lost to feasibility
• Individual factors examined
• Personal experiences as camp counselor
![Page 7: Systematic review of the factors influencing literacy ...msjohnsonscienceclass.weebly.com/uploads/9/2/2/1/9221026/sample_ppt.pdfsystematic review of the factors influencing literacy](https://reader036.fdocuments.in/reader036/viewer/2022062603/5f155c7974fdd606d5419e82/html5/thumbnails/7.jpg)
HYPOTHESIS
Age of initial device implementation, user compliancy, and pre-school
literacy education will have a greater influence on literacy development
in children with cochlear implants (CIs) and/or hearing aids (HAs) than
factors traditionally considered influential in literacy intervention.

CONCLUSIONS
• No factors more influential than others
• Hypothesis not supported
• Trends demonstrate importance of critical periods
• Communication mode’s influence
• Indicates further research needed

CONCLUSIONS
• User compliancy not examined
• Relation to length of use
• Recommend professionals emphasize these factors
