Issues to consider
How does performance change as a function of the numbers of channels in quiet and in noise? Is there an interaction between the two main factors in the experiment?
Although native English speakers can do quite well in perceiving sentences re-constructed with as few as 4 channels, non-native speakers require more channels to reach the same levels of performance. How might this finding be accounted for?
What implications does this experiment have regarding the optimal number of electrodes in multi-channel cochlear implants?
What implications for clinical practice might these findings have?
