  2. Aim • Use nonauditory training task to engage attention and improve memory of cochlear implant subjects. • Relevance • Auditory training significantly improves cochlear implant users’ speech and music perception. • However, it is unclear whether performance gains are due to improved auditory perception or to generally improved attention, memory, and/or cognitive processing.

  3. Method • Assessed speech and music perception and auditory and visual memory in 10 cochlear implant users before, during, and after training with nonauditory visual digit span (VDS) task.

  4. Results • VDS performance: • Significantly improved after VDS training. • Auditory outcome measures: • Most did not significantly improve. • However, small (but significant) improvements in vocal emotion recognition and melodic contour identification. • Posttraining gains much smaller with nonauditory VDS training than in previous auditory training studies with cochlear implant users.

  5. Conclusion • Results suggest that: • Posttraining gains in previous studies were not solely attributable to improved attention or memory. • More likely due to improved auditory perception. • Cochlear implant users may require targeted auditory training to improve speech and music perception.
