q3 i? PIQ, younger age at implantation, smallest sign enhancement, longer digit spans and shorter sentence durations predicted higher CI-HS language; combined predictors explained 70% of variance. → Geers Ann E. 2011

Geers Ann E. 2011¶

Geers Ann E., Sedey Allison L. (2011). Language and Verbal Reasoning Skills in Adolescents with 10 or More Years of Cochlear Implant Experience. Ear and Hearing. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3157037/

Hierarchical regression (Table 5) on CI-HS measures: step 1 explained 34% (sign enhancement β = −.345, p <.001); digit span and sentence duration added 15%; early language PC added 20% (β = 0.665, p <.001); total 70% of variance predicted.

"In addition, students who received their CI at the youngest ages (or shortly after onset of profound deafness) and those whose vocabulary score was not improved with the addition of sign (i.e., smallest difference in PPVT scores at SC and OC administrations) demonstrated the highest language scores at CI-HS."

Discussion¶

Learner Variables¶

• Access — predictor: learners who differ on it differ in outcomes
