Summary of the Statistical Contrast Between d′ Scores Obtained by CI Listeners and IO Model for Each Electrode Separation.
| Electrode separation | Difference estimate | t ratio | p |
|---|---|---|---|
| 0 | 0.220 | 0.932 | .992 |
| 1 | 0.619 | 2.627 | .290 |
| 3 | 1.147 | 4.870 | .007 |
| 5 | 1.645 | 6.984 | <.001 |
| 8 | 1.574 | 6.683 | <.001 |
Note. Statistical contrasts were performed on the lsmeans estimates from the mixed-effects linear model for each data type and electrode separation (df = 13.83). IO = ideal observer; CI = cochlear implant.
