q3 i? CI-HS students averaged a Word Attack quotient of 70 (2 SD below norms), made 62% phonologically plausible spelling errors versus 89% for controls, and repeated only 42% of phonemes correctly versus 96% for controls. → Geers Ann E.; Hayes Heather 2011

q3 · i? · associational · r2

Comparison of phonologically plausible spelling errors between CI-HS students and the 46-student hearing control group. Hearing controls made "more plausible errors than the CI-HS group (89%)" versus 62% for CI students, significant at p < .001. Word Attack averaged 70, Elision 6.9, and nonword repetition 42% phonemes correct versus 96% for controls.

"The NHC-HS students made proportionally more plausible errors than the CI-HS group (89%), and this difference was significant (Mann-Whitney U = 4230, z = 6.473, p < .001)"
