Effectiveness of Computer-Based Auditory Training for Adult Cochlear Implant Users: A Randomized Crossover Study

Area of Science:

• Audiology
• Cognitive Science
• Rehabilitation

Background:

• Cochlear implantation improves hearing but challenges remain in noisy environments.
• Auditory training (AT) and cognitive training are potential interventions to enhance speech perception in noise.

Purpose of the Study:

• To evaluate the effectiveness of computer-based auditory training (AT) for speech perception in noise.
• To assess if computer-based visual training (VT) targeting cognitive skills yields similar outcomes.
• To determine if training leads to improvements in listening, cognition, and quality of life.

Main Methods:

• A randomized crossover study with 26 adult cochlear implant users.
• Participants underwent 6 weeks of AT followed by 6 weeks of VT, or vice versa.
• Outcome measures for listening, cognition, and quality of life were assessed repeatedly.

Main Results:

• Both AT and VT programs showed statistically significant improvements in verbal recognition, particularly for consonants in words, within the first two weeks.
• This on-task learning did not result in significant improvements in untrained outcome measures.
• No clear transfer of training gains to broader listening, cognitive, or quality of life measures was observed.

Conclusions:

• Experienced cochlear implant users may not benefit from significant transfer of learning from computer-based AT or VT to untrained tasks.
• Further research is needed to optimize training protocols for transfer of benefits in cochlear implant users.
