Succeeding in such environments requires a listener to first segregate sound sources and then selectively attend to the source of interest. This study examines how individual auditory spatial cues (interaural time differences and interaural level differences) support spatial selective attention, the cortical processes that underlie this ability, and how these processes are modulated by task demands. Participants with normal hearing and participants who use bilateral cochlear implants will perform listening tasks while brain and physiological responses are recorded (electroencephalography, functional near-infrared spectroscopy, pupillometry, and, for normal-hearing participants only, functional magnetic resonance imaging). The findings will provide new insights into the mechanisms of spatial selective attention and help guide clinical solutions for cochlear implant users, individuals with hearing impairment more generally, and older normal-hearing adults who have difficulty understanding speech in noisy environments.",[28,29,30],"Bilateral Cochlear Implants","Hearing Loss, Bilateral","Healthy",[32,33,34,35,36,37,38,39,40,41],"spatial hearing","auditory selective attention","interaural level difference","interaural time difference","cochlear implant","EEG","fNIRS","fMRI","pupillometry","speech in noise","RECRUITING","2026-08-10",{"date":45,"type":46},"2026-08-14","ACTUAL",{"date":48,"type":46},"2025-10-22",{"date":50,"type":22},"2030-07",{"name":52,"class":53},"University of South Florida","OTHER",1,{"id":56,"slug":57,"hasResults":11,"nctId":58,"briefTitle":59,"officialTitle":59,"acronym":60,"eligibilityCriteria":61,"healthyVolunteers":11,"sex":17,"minAge":62,"maxAge":63,"enrollmentInfo":64,"targetDuration":4,"studyType":66,"phases":4,"briefSummary":67,"conditions":68,"keywords":4,"overallStatus":70,"whyStopped":4,"lastUpdateSubmitDate":71,"lastUpdatePostDateStruct":72,"startDateStruct":74,"completionDateStruct":76,"leadSponsor":78,"locationsCount":4},"100649773","investigating-the-neural-oscillatory-features-for-limited-access-to-oral-language-in-deaf-children-with-early-bilateral-cochlear-implantation-100649773","NCT07739433","Investigating the Neural Oscillatory Features for Limited Access to Oral Language in Deaf Children With Early Bilateral Cochlear Implantation","ICO","Inclusion Criteria:\n\n* Between 4 and 17 years old at time of inclusion\n* Age of first implantation less than or equal to 30 months\n* Bilateral CIs\n* Received CIs simultaneously or sequentially (the interval between two implantations does not exceed 18 months)\n* Congenital severe-to-profound hearing loss (PTA ≥90 dB HL)\n\nExclusion Criteria:\n\n* Children with severe associated disabilities who are assessed as unable to complete the tasks\n* Patients who, in the medical opinion of the Investigator, are unlikely to comply with the study protocol","4 Years","17 Years",{"count":65,"type":22},150,"OBSERVATIONAL","Children with severe-to-profound congenital hearing loss often experience significant language development challenges.
